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. In case you have installed the gnome-menus package, you can set the value in your
.xinitrc file with the line :
If you have e.g.
/etc/gtk-2.0/gtkrc and add the following line:
gtk-icon-theme-name = "oxygen"
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

~/.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.

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
