Opera is a web browser and internet suite developed by Opera Software
- "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." [1]

Installation
Opera has been moved to the AUR due to licensing issues.
To install the latest stable Opera with yaourt:
$ yaourt -S opera
Static build
Opera is also available statically linked against the Qt libraries. This is preferable if the associated Qt packages are not wanted.
Download the opera-static package for i686 (Obsolete: not updated to Opera 10 as of Sep 2009) in the AUR.
KDE integration
In recent versions of Opera there is a somewhat obscure option -systemstyle 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 opera:config advanced options.
Optional tweaks
- To remove the tray icon, launch Opera with the -notrayicon 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 qtconfig (/usr/bin/qtconfig, installed as a dependency for the non-static Opera package).
- To make Opera use KDE icons, download a native skin such as fixed window skin
- To improve flash performance in Opera, issue this command before starting opera, or add it to ~/.bash_profile (alternatively, /etc/profile to make the change system-wide):
export OPERAPLUGINWRAPPER_PRIORITY=0
Microsoft fonts and Opera
If ttf-ms-fonts 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.
3. rm -rf ~/.opera
4. Finally, run Opera again. You can reinstall ttf-ms-fonts after doing this.
Troubleshooting
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.
2. Add to ~/.bash_profile, or /etc/profile to make this setting affect all logins:
# 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 libjvm.so:
# 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.
Simply type:
opera:config
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.
