- The browser handles common Internet-related tasks such as displaying websites, sending and receiving e-mail messages, managing contacts, IRC online chatting, downloading files via BitTorrent, and reading web feeds. Opera is offered free of charge for personal computers and mobile phones, but for other devices it must be paid for. Wikipedia:Opera (web browser)
Opera has been moved to the AUR due to licensing issues.
To install the latest stable Opera with yaourt:
$ yaourt -S opera
Opera is also available statically linked against the Qt libraries. This is preferable if the associated Qt packages are not wanted.
Download the Template:Package AUR package for i686 (Obsolete: not updated to Opera 10 as of Sep 2009) in the AUR.
Opera can use Mozilla-based plugins; see Browser Plugins for details. The plugin path can be specified at Tools > Preferences > Advanced > Content > Plug-in Options..., but the defaults should work fine for most users.
In recent versions of Opera there is a somewhat obscure option Template:Codeline which will apply KDE style settings instead of plain QT. However, you should test yourself your KDE selected theme is not causing instabilities i.e., sudden browser crashes.
If dialogs don't work for you, make sure
File Selector -> Dialog Toolkit = 0
in Template:Codeline advanced options.
- To remove the tray icon, launch Opera with the Template:Codeline option.
$ opera -notrayicon
- Make sure mail extension is not used.
$ opera -nomail
- To make the menus look integrated with Qt, install your preferred Qt4 theme and apply it by using Template:Codeline (Template:Filename, installed as a dependency for the non-static Opera package).
- To improve flash performance in Opera, issue this command before starting opera, or add it to Template:Filename (alternatively, Template:Filename to make the change system-wide):
Microsoft fonts and Opera
If Template:Package Official has been installed before running Opera for the first time, Opera will use those fonts by default, regardless of what's specified by local GTK options, GNOME or KDE font management, etc.
To make Opera use options set by your font manager:
1. Before proceding, close every Opera instance.
2. Uninstall ttf-ms-fonts.
4. Finally, run Opera again. You can reinstall ttf-ms-fonts after doing this.
Java on Arch64
1. Install a Java environment:
# pacman -S openjdk
For the open source version, or:
# pacman -S jre
For Sun's proprietary version.
# openjdk export LD_LIBRARY_PATH=/usr/lib/jvm/java-6-openjdk/jre/lib/amd64/server/ # jre export LD_LIBRARY_PATH=/opt/java/jre/lib/amd64/server/
Alternatively, create a symlink to Template:Filename:
# openjdk cd /usr/lib/jvm/java-6-openjdk/jre/lib/amd64 ln -s server/libjvm.so . # jre cd /opt/java/jre/lib/amd64 ln -s server/libjvm.so .
3. Edit the path to Java in Opera: Menu -> Tools -> Preferences -> Advanced -> Content -> Java Options.
#openjdk /usr/lib/jvm/java-6-openjdk/jre/lib/amd64/ #jre /opt/java/jre/lib/amd64/
Fonts seem too big
Forcing Opera to use an specific DPI setting (not needed since Opera 10) might be a solution.
In the address bar and search for "dpi". After setting the desired DPI in the "Force DPI" field, store altered settings by clicking on "Save".
Slow scrolling on nVidia cards
Try running the following command:
$ nvidia-settings -a InitialPixmapPlacement=2
On some computers, http://helion.pl works extremely slow without this hack, making it a perfect site for testing.
Left and right scroll go through history
To make the horizontal scroll on your mouse do horizontal scrolling in opera, go to Settings→Preferences→Advanced→Shortcuts→Mouse set-up.
Select Edit and search for "Forward" and "Back", edit the action for "button5", "button6", "button7" and "button8" to "scroll left" or "scroll right".
Enjoy horizontal scrolling in Opera.
