[https://wiki.lxde.org/en/PCManFM PCManFM] is a free file manager application and the standard file manager of [[LXDE]].
  
'''PCManFM''' is "an extremly fast, lightweight, yet feature-rich file manager with tabbed browsing". Source: [http://pcmanfm.sourceforge.net/ PCManFM on sourceforge]. PCManFM is the default file manager of the [[LXDE]] (Lightweight X11 Desktop Environment).
+
== Installation ==
  
==Installation==
+
[[Install]] the {{Pkg|pcmanfm}} package, or {{Pkg|pcmanfm-gtk3}} for the GTK3 version, or {{AUR|pcmanfm-git}} for the development version. {{Pkg|gvfs}} is recommended for trash support, mounting with [[udisks]] and remote filesystems.
Run the following command to install:
 
# pacman -S pcmanfm
 
  
You will also require gamin (a replacement for fam, which required a daemon) to pick up events such as files and directories changes. This is required by PCManFM to start:
+
[[Qt]] variants are available through {{Pkg|pcmanfm-qt}} and {{AUR|pcmanfm-qt-git}}.
  
# pacman -S gamin
+
== Desktop management ==
 +
The command to allow PCManFM to set wallpapers and enable the use of desktop icons is:
  
Then launch PCManFM with:
+
  pcmanfm --desktop
  $ pcmanfm
 
  
==Volume handling==
+
The native desktop menu of the window manager will be replaced with that provided by PCManFM. However, it can easily be restored from the PCManFM menu itself by selecting {{ic|Desktop preferences}} and then enabling the {{ic|Right click shows WM menu}} option in the {{ic|Desktop}} tab.
PCManFM is able to mount and unmount devices, both manually and automatically. This feature is offered as an alternative to CLI tools such as [[pmount]]. There are various 'up-to-date' versions of PCManFM (see below), and different volume handling strategies can be chosen.
 
  
===PCManFM2 and udisks===
+
=== Desktop preferences ===
The last official release of PCManFM is able to handle volumes with udisks. Just follow the instuctions below:
+
If using the native desktop menu provided by a window manager, enter the following command to set or amend desktop preferences at any time:
# Start the DBUS daemon, manually or editing your rc.conf file.
 
# In your .xinitrc file, which starts your Window Manager, edit the 'exec' line like the following:
 
{{File|name=.xinitrc|content=exec ck-launch-session dbus-launch --sh-syntax --exit-with-session <WM>}}
 
  
===PCManFM2 and gvfs===
+
$ pcmanfm --desktop-pref
If you prefer to use the Gnome Virtual FileSystem, PCManFM2 allows you to do so. The procedure is the same as before, but you obviously have to install additional packages:
 
* [[gvfs]] (and dependencies);
 
* (optional) gvfs-smb, gvfs-obexftp, gvfs-afc, etc. in order to support additional features.
 
  
==Troubleshooting==
+
It is worthwhile to consider adding this command to a keybind and/or the native desktop menu for easy access.
===No icons?===
 
If you are using a window manager over a desktop environment and notice you have no icons for folders and files, install an icon theme:
 
# pacman -S tango-icon-theme
 
  
Then edit {{Filename|~/.gtkrc-2.0}} '''or''' {{Filename|/etc/gtk-2.0/gtkrc}} and add the following line:
+
=== Creating new icons ===
gtk-icon-theme-name = "Tango"
+
User content such as text files, documents, images and so forth can be dragged and dropped directly onto the desktop. To create shortcuts for applications it will be necessary to copy their {{ic|.desktop}} files to the {{ic|~/Desktop}} directory itself. Do not drag and drop the files there as they will be moved completely. The syntax of the command to do so is:  
  
===Mounting as normal user with GVFS and PCManFM2===
+
cp /usr/share/applications/<name of application>.desktop ~/Desktop
It may be necessary to follow several steps in order for GVFS in PCManFM2 to allow normal users to mount drives. This includes having the [http://wiki.archlinux.org/index.php/Dbus D-Bus] daemon running, and adding the following to your .xinitrc (before any instance of pcmanfm is started):
 
  
{{File|name=~/.xinitrc|content=
+
For example - where installed - to create a desktop shortcut for {{pkg|lxterminal}}, the following command would be used:
if which dbus-launch >/dev/null && test -z "$DBUS_SESSION_BUS_ADDRESS"; then
 
      eval "$(dbus-launch --sh-syntax --exit-with-session)"
 
fi
 
}}
 
  
 +
cp /usr/share/applications/lxterminal.desktop ~/Desktop
  
Then edit the file {{Filename|/usr/share/polkit-1/actions/org.freedesktop.devicekit.disks.policy}} Or if that file is empty edit this file {{Filename|/usr/share/polkit-1/actions/org.freedesktop.udisks.policy}}
+
For those who used the [[XDG user directories]] program to create their {{ic|$HOME}} directories no further configuration will be required.
and replace all instances of
 
  
<allow_any>no</allow_any>

== Daemon mode ==
  
with

To run PCManFM in the background (to for example automatically mount removable media), use:
 
<allow_any>yes</allow_any>
 
(Credits to karabaja4 -- http://forum.lxde.org/viewtopic.php?t=1422&f=22)
 
  
===NTFS Read/Write Support===

  pcmanfm -d
Install ntfs-3g:
 
  # pacman -S ntfs-3g
 
  
===gnome-open opens "Find" dialog instead of the directory===

Should automount fail, see [[udisks]].
Remove or rename the file {{Filename|/usr/share/applications/pcmanfm-find.desktop}}. If you're running pcmanfm-mod from AUR, remove or rename the file {{Filename|/usr/share/applications/pcmanfm-mod-find.desktop}}.
 
  
==Available Versions==
+
== Autostarting ==
There are several versions of PCManFM currently available:
+
How PCManFM may be autostarted as a [[daemon]] process or to manage the desktop for a standalone [[window manager]] will depend on the window manager itself. For example, to enable management of the desktop for [[Openbox]], the following command would be added to the {{ic|~/.config/openbox/autostart}} file:
  
===PCManFM2===
+
pcmanfm --desktop &
This is the package in Arch's extra repository as "pcmanfm". The current git test version of it is available in the AUR as [http://aur.archlinux.org/packages.php?ID=33601 pcmanfm-git]. The original author of PCManFM (Hon Jen Yee aka PCMan) is in the process of rewriting the program, which is currently in testing.  This rewrite is sometimes referred to as "pcmanfm2", although its current version number is 0.9.7 RC1. This version uses GVFS for mounting and volume management.  More information is available on the [http://forum.lxde.org/viewforum.php?f=22 LXDE Forum].
 
  
===PCManFM 0.5.2===
+
Review the relevant wiki article and/or official home page for a particular installed or intended window manager. Should a window manager not provide an autostart file, PCManFM may be alternatively autostarted by editing one or both of the following files:
The legacy PCManFM (version 0.5.2, which is currently "pcmanfm-gtk220" in the AUR repository) is frozen and is no longer being maintained by the original author.  This version uses HAL for mounting. More information is available on the [http://pcmanfm.sourceforge.net/intro.html project page].
 
  
===PCManFM-Mod===
+
* [[xinitrc]]: When using the [[SLiM]] [[display manager]] or [[Startx]] command
PCManFM-Mod adds user-definable commands, other features, and bugfixes to the legacy version of the PCManFM file manager v0.5.2. This version builds and installs as "pcmanfm-mod" and will run independently of other versions of PCManFM you have installed on your system. This legacy version is still desired by some due to more stability than the newer 0.9.x rewrite in progress, less Gnome dependencies, and the use of HAL rather than gnome-vfs.  PCManFM-Mod is available in the [http://aur.archlinux.org/packages.php?ID=34819 AUR as pcmanfm-mod] and as [http://aur.archlinux.org/packages.php?ID=39547 pcmanfm-mod-prov] (latter provides pcmanfm).  More information is available at [http://igurublog.wordpress.com/downloads/mod-pcmanfm/ IgnorantGuru's Blog].

 +
 
 +
== Additional features and functionality ==
 +
Less experienced users should be aware that a file manager alone - especially when installed in a standalone [[Window manager]] such as [[Openbox]] - will not provide the features and functionality users of full desktop environments such as [[Xfce]] and [[KDE]] will be accustomed to. Review the [[file manager functionality]] article for further information.
 +
 
 +
== Tips and tricks ==
 +
 
 +
=== Get thumbnails for other file types ===
 +
 
 +
{{Merge|File manager functionality#Thumbnail Previews|This section is not specific to PCManFM.}}
 +
 
 +
PCManFM supports image thumbnails out of the box. However, in order to view thumbnails of other file types, PCManFM uses the information provided in the files located at {{ic|/usr/share/thumbnailers}}. The packages which provide a thumbnailer usually add the corresponding ''.thumbnail'' file at {{ic|/usr/share/thumbnailers}}. For example, in order to get thumbnails for OpenDocument files, you may install {{Pkg|libgsf}} from the official repositories. For video files' thumbnails, the package {{Pkg|ffmpegthumbnailer}} is required. For PDF files, you may install {{Pkg|evince}} from the official repositories, which provides {{ic|evince-thumbnailer}} and the corresponding file at {{ic|/usr/share/thumbnailers}}. However, if you prefer not to install {{ic|evince}}, you can also replicate the functionality of {{ic|evince-thumbnailer}} using {{Pkg|imagemagick}}'s {{ic|convert}} command. This is accomplished by creating a new file with the ''.thumbnailer'' extension (e.g.: {{ic|imagemagick-pdf.thumbnailer}}) at {{ic|/usr/share/thumbnailers}} with the following content:
 +
 
 +
  [Thumbnailer Entry]
 +
  TryExec=convert
 +
  Exec=convert %i[0] -thumbnail %s %o
 +
  MimeType=application/pdf;application/x-pdf;image/pdf;
 +
 
 +
{{Note|The ''[0]'' next to the input file is specified so that {{ic|convert}} only generates a thumbnail of the first page. This is a {{ic|convert}}-specific syntax and has nothing to do with the syntax of the thumbnailers' files.}}
 +
 
 +
Following this example, you can specify custom thumbnailers by creating your own ''.thumbnail'' files. Keep in mind that {{ic|%i}} refers to the input file (the file which will have its thumbnail made), {{ic|%o}} to the output file (the thumbnail image) and {{ic|%s}} to the size of the thumbnail. These parameters will be automatically substituted with the corresponding data and passed to the thumbnailer program by PCManFM.
 +
 
 +
{{Tip|If you only get thumbnails of certain files and not of all the files of the same type try increasing the maximum file size of the files that get a thumbnail at ''Edit > Preferences > Display''.}}
 +
 
 +
=== Set the terminal emulator ===
 +
 
 +
You can configure what terminal emulator PCManFM should use for ''Tools > Open Current Folder in Terminal'' under ''Edit > Preferences > Advanced'' e.g. {{ic|bash -c 'pantheon-terminal --working-directory "$PWD"'}}.
 +
 
 +
=== Integrate an archiver ===
 +
 
 +
You can choose the integrated archiver under ''Edit > Preferences > Advanced''. PCManFM supports {{Pkg|file-roller}}, {{Pkg|xarchiver}} (or {{Pkg|xarchiver-gtk2}}), {{Pkg|engrampa}}, {{Pkg|ark}} and {{Aur|squeeze-git}}.
 +
 
 +
=== Templates are accessible under ''Create New...'' ===
 +
 
 +
PCManFM adds the files in {{ic|~/Templates}} as ''Create New...'' context menu items on startup.
 +
 
 +
== Troubleshooting ==
 +
 
 +
=== Open With dialog window empty ===
 +
 
 +
If you do not see any applications to choose from in the open with dialog, then you can try removing {{Pkg|gnome-menus}} and instead install {{Pkg|lxmenu-data}}. Furthermore, export the following variables:
 +
 
 +
export XDG_MENU_PREFIX=lxde-
 +
  export XDG_CURRENT_DESKTOP=LXDE
 +
 
 +
=== No "Applications" ===
 +
 
 +
You can try this method: Delete all files in the {{ic|$HOME/.cache/menus}} directory, and run PCManFM again.
 +
 
 +
PCManFM requires the environment variable ''XDG_MENU_PREFIX'' to be set. The value of the variable should match the beginning of a file present in the {{ic|/etc/xdg/menus/}} directory. E.g. you can set the value in your {{ic|.xinitrc}} file with the line:
 +
export XDG_MENU_PREFIX="lxde-"
 +

 +
 
 +
=== No icons ===
 +
 
 +
If you are using a [[window manager]] instead of a [[desktop environment]] and you have no icons for folders and files, specify a GTK+ icon theme.
 +
 
 +
If you have e.g. {{Pkg|oxygen-icons}} installed, edit {{ic|~/.gtkrc-2.0}} '''or''' {{ic|/etc/gtk-2.0/gtkrc}} and add the following line:
 +
gtk-icon-theme-name = "oxygen"
 +
{{Note|All instances of PCManFM have to be restarted for changes to apply!}}
 +
 
 +
Else, use an different one (''gnome'', ''hicolor'', and ''locolor'' do not work). To list all installed icon themes:
 +
  $ ls ~/.icons/ /usr/share/icons/
 +
 
 +
If none of them is suitable, install one. To list all installable icon packages:
 +
$ pacman -Ss icon-theme
 +
{{Tip|For an alternative GUI solution, install {{Pkg|lxappearance}} and apply an icon theme from there.}}
 +
 
 +
=== No "Previous/Next Folder" functionality with mouse buttons ===
 +
 
 +
A method to fix this is with [[Xbindkeys]].
 +
 
 +
Install {{Pkg|xbindkeys}}, {{AUR|xvkbd}} and edit {{ic|~/.xbindkeysrc}} to contain the following:
 +
{{bc|<nowiki>
 +

"/usr/bin/xvkbd -text '\[Alt_L]\[Left]'"
 +
b:8
 +
"/usr/bin/xvkbd -text '\[Alt_L]\[Right]'"
 +
b:9
 +
</nowiki>}}
 +
Actual button codes can be obtained with package {{Pkg|xorg-xev}}.
 +
 
 +
Add:

to your {{ic|~/.xinitrc}} to execute xbindkeys on log-in.
 +
 
 +
=== --desktop parameter not working or crashing X-server ===
 +
 
 +
Make sure you have ownership and write permissions on {{ic|~/.config/pcmanfm}}.
 +
 
 +
Setting the wallpaper either by using the {{ic|--desktop-pref}} parameter or editing {{ic|~/.config/pcmanfm/default/pcmanfm.config}} solves the problem.
 +
 
 +
=== Terminal emulator advanced configuration not saved ===
 +
 
 +
Make sure you have rights on libfm configuration file:
 +
 
 +
$ chmod -R 755 ~/.config/libfm
 +
$ chmod 644 ~/.config/libfm/libfm.conf
 +
 
 +
=== Make PCManFM remember your preferred Sort Files settings ===
 +
 
 +
You can use ''View > Sort Files'' to change the order in which PCManFM lists the files, but PCManFM won't remember that the next time you start it. To make it remember, go to ''Edit > Preferences'' and close. That will write your current sort_type and sort_by values into {{ic|~/.config/pcmanfm/LXDE/pcmanfm.conf}}.

Revision as of 07:48, 13 January 2018

PCManFM is a free file manager application and the standard file manager of LXDE.

Installation

Install the pcmanfm package, or pcmanfm-gtk3 for the GTK3 version, or pcmanfm-gitAUR for the development version. gvfs is recommended for trash support, mounting with udisks and remote filesystems.

Qt variants are available through pcmanfm-qt and pcmanfm-qt-gitAUR.

Desktop management

The command to allow PCManFM to set wallpapers and enable the use of desktop icons is:

pcmanfm --desktop

The native desktop menu of the window manager will be replaced with that provided by PCManFM. However, it can easily be restored from the PCManFM menu itself by selecting Desktop preferences and then enabling the Right click shows WM menu option in the Desktop tab.

Desktop preferences

If using the native desktop menu provided by a window manager, enter the following command to set or amend desktop preferences at any time:

$ pcmanfm --desktop-pref

It is worthwhile to consider adding this command to a keybind and/or the native desktop menu for easy access.

Creating new icons

User content such as text files, documents, images and so forth can be dragged and dropped directly onto the desktop. To create shortcuts for applications it will be necessary to copy their .desktop files to the ~/Desktop directory itself. Do not drag and drop the files there as they will be moved completely. The syntax of the command to do so is:

cp /usr/share/applications/<name of application>.desktop ~/Desktop

For example - where installed - to create a desktop shortcut for lxterminal, the following command would be used:

cp /usr/share/applications/lxterminal.desktop ~/Desktop

For those who used the XDG user directories program to create their $HOME directories no further configuration will be required.

Daemon mode

To run PCManFM in the background (to for example automatically mount removable media), use:

pcmanfm -d

Should automount fail, see udisks.

Autostarting

How PCManFM may be autostarted as a daemon process or to manage the desktop for a standalone window manager will depend on the window manager itself. For example, to enable management of the desktop for Openbox, the following command would be added to the ~/.config/openbox/autostart file:

pcmanfm --desktop &

Review the relevant wiki article and/or official home page for a particular installed or intended window manager. Should a window manager not provide an autostart file, PCManFM may be alternatively autostarted by editing one or both of the following files:

Additional features and functionality

Less experienced users should be aware that a file manager alone - especially when installed in a standalone Window manager such as Openbox - will not provide the features and functionality users of full desktop environments such as Xfce and KDE will be accustomed to. Review the file manager functionality article for further information.

Tips and tricks

Get thumbnails for other file types

Merge-arrows-2.pngThis article or section is a candidate for merging with File manager functionality#Thumbnail Previews.Merge-arrows-2.png

Notes: This section is not specific to PCManFM. (Discuss in Talk:PCManFM#)

PCManFM supports image thumbnails out of the box. However, in order to view thumbnails of other file types, PCManFM uses the information provided in the files located at /usr/share/thumbnailers. The packages which provide a thumbnailer usually add the corresponding .thumbnail file at /usr/share/thumbnailers. For example, in order to get thumbnails for OpenDocument files, you may install libgsf from the official repositories. For video files' thumbnails, the package ffmpegthumbnailer is required. For PDF files, you may install evince from the official repositories, which provides evince-thumbnailer and the corresponding file at /usr/share/thumbnailers. However, if you prefer not to install evince, you can also replicate the functionality of evince-thumbnailer using imagemagick's convert command. This is accomplished by creating a new file with the .thumbnailer extension (e.g.: imagemagick-pdf.thumbnailer) at /usr/share/thumbnailers with the following content:

  [Thumbnailer Entry]
  TryExec=convert
  Exec=convert %i[0] -thumbnail %s %o
  MimeType=application/pdf;application/x-pdf;image/pdf;
Note: The [0] next to the input file is specified so that convert only generates a thumbnail of the first page. This is a convert-specific syntax and has nothing to do with the syntax of the thumbnailers' files.

Following this example, you can specify custom thumbnailers by creating your own .thumbnail files. Keep in mind that %i refers to the input file (the file which will have its thumbnail made), %o to the output file (the thumbnail image) and %s to the size of the thumbnail. These parameters will be automatically substituted with the corresponding data and passed to the thumbnailer program by PCManFM.

Tip: If you only get thumbnails of certain files and not of all the files of the same type try increasing the maximum file size of the files that get a thumbnail at Edit > Preferences > Display.

Set the terminal emulator

You can configure what terminal emulator PCManFM should use for Tools > Open Current Folder in Terminal under Edit > Preferences > Advanced e.g. bash -c 'pantheon-terminal --working-directory "$PWD"'.

Integrate an archiver

You can choose the integrated archiver under Edit > Preferences > Advanced. PCManFM supports file-roller, xarchiver (or xarchiver-gtk2), engrampa, ark and squeeze-gitAUR.

Templates are accessible under Create New...

PCManFM adds the files in ~/Templates as Create New... context menu items on startup.

Troubleshooting

Open With dialog window empty

If you do not see any applications to choose from in the open with dialog, then you can try removing gnome-menus and instead install lxmenu-data. Furthermore, export the following variables:

export XDG_MENU_PREFIX=lxde-
export XDG_CURRENT_DESKTOP=LXDE

No "Applications"

You can try this method: Delete all files in the $HOME/.cache/menus directory, and run PCManFM again.

PCManFM requires the environment variable XDG_MENU_PREFIX to be set. The value of the variable should match the beginning of a file present in the /etc/xdg/menus/ directory. E.g. you can set the value in your .xinitrc file with the line:

export XDG_MENU_PREFIX="lxde-"

See these threads for more informations: [1], and especially this post from the Linux Mint forums: [2]

No icons

If you are using a window manager instead of a desktop environment and you have no icons for folders and files, specify a GTK+ icon theme.

If you have e.g. oxygen-icons installed, edit ~/.gtkrc-2.0 or /etc/gtk-2.0/gtkrc and add the following line:

gtk-icon-theme-name = "oxygen"
Note: All instances of PCManFM have to be restarted for changes to apply!

Else, use an different one (gnome, hicolor, and locolor do not work). To list all installed icon themes:

$ ls ~/.icons/ /usr/share/icons/

If none of them is suitable, install one. To list all installable icon packages:

$ pacman -Ss icon-theme
Tip: For an alternative GUI solution, install lxappearance and apply an icon theme from there.

No "Previous/Next Folder" functionality with mouse buttons

A method to fix this is with Xbindkeys.

Install xbindkeys, xvkbdAUR and edit ~/.xbindkeysrc to contain the following:

# Sample .xbindkeysrc for a G9x mouse.
"/usr/bin/xvkbd -text '\[Alt_L]\[Left]'"
 b:8
"/usr/bin/xvkbd -text '\[Alt_L]\[Right]'"
 b:9

Actual button codes can be obtained with package xorg-xev.

Add:

xbindkeys &

to your ~/.xinitrc to execute xbindkeys on log-in.

--desktop parameter not working or crashing X-server

Make sure you have ownership and write permissions on ~/.config/pcmanfm.

Setting the wallpaper either by using the --desktop-pref parameter or editing ~/.config/pcmanfm/default/pcmanfm.config solves the problem.

Terminal emulator advanced configuration not saved

Make sure you have rights on libfm configuration file:

$ chmod -R 755 ~/.config/libfm
$ chmod 644 ~/.config/libfm/libfm.conf

Make PCManFM remember your preferred Sort Files settings

You can use View > Sort Files to change the order in which PCManFM lists the files, but PCManFM won't remember that the next time you start it. To make it remember, go to Edit > Preferences and close. That will write your current sort_type and sort_by values into ~/.config/pcmanfm/LXDE/pcmanfm.conf.

"Not authorized" error when attempting to mount drive

Make this polkit rule in /etc/polkit-1/rules.d/00-mount-internal.rules:

polkit.addRule(function(action, subject) {
   if ((action.id == "org.freedesktop.udisks2.filesystem-mount-system" &&
      subject.local && subject.active && subject.isInGroup("storage")))
      {
         return polkit.Result.YES;
      }
});

And add your user to storage group:

# usermod -aG storage username

Operation not supported

See the General troubleshooting article on Session permissions.
