Opera is a full-featured web suite by Opera Software ASA, a Norwegian IT company.
Why should I use Opera?
- It's fast and lightweight.
- It's standards-compliant.
- It's very customizable.
- Out-of-the-box provides web browsing with mouse gestures and ad-blocking, mail client, BitTorrent client and IRC client all in one! And then some more too...
- It's got a professional touch: no software bloat, no memory leaks, no freezes, no crashes.
Why should I NOT use Opera?
- It is not free. It's proprietary software.
- If you use GNOME or some window manager based on GTK+, it is needed to load additional libraries because Opera it's a Qt application.
- Some webpages don't display correctly because they are not following the web standards (Opera sticks to standards).
To install the latest stable Opera:
# pacman -S opera
Note: this will install Qt4 shared build.
Note 2: on x86_64, it will install Qt3.
Opera is also available statically linked against the Qt libraries, removing them as dependencies.
It is available for i686 as "opera-static" in the AUR.
Microsoft Fonts and Opera
If you have at the time of Opera package installation the package ttf-ms-fonts Opera will then use those fonts which may look unattractive. To make Opera use by default Gnome fonts or whatever is default on your system remove the ttf-ms-fonts package and then install Opera.
Also note that all fonts are configurable at Tools -> Preferences -> Advanced -> Fonts
- To remove the tray icon, launch Opera with the -notrayicon option.
- To make the menus look nice, do
# pacman -S polymer
then run qtconfig (it will be located in /opt/qt/bin) and set the polymer theme for Qt applications.
- To disable "ugly" non anti-aliased fonts, type opera:config in the Opera address bar, then search for "core X fonts" and disable them.
- To improve the (flash) plugin performance in opera, just issue this command before starting opera or add it to your /etc/profile:
# export OPERAPLUGINWRAPPER_PRIORITY=0
Java on Arch64
Install your favorite java environment:
# pacman -S jre
# pacman -S openjdk
Add to the bottom of your /etc/profile:
# For jre package: export LD_LIBRARY_PATH=/opt/java/jre/lib/amd64/server/
#For openjdk package: export LD_LIBRARY_PATH=/usr/lib/jvm/java-1.6.0-openjdk/jre/lib/amd64/server/
- If you get the following error:
/usr/lib/opera/9.27-20080331.6/opera: error while loading shared libraries: libqt-mt.so.3: cannot open shared object file: No such file or directory
Create a symlink (as root):
# ln -s /opt/qt/lib/libqt-mt.so.3 /usr/lib/libqt-mt.so.3
That should fix the problem.
- If you sometimes have rendering problems, like duplicated pixel rows, turn of "smooth scrolling" (Tools -> Preferences -> Advanced -> Browsing -> Smooth scrolling)
Not sure what this caused by. But here is another solution. Be sure to remove opera before you proceed.
- Add the this to the bottom of /etc/pacman.conf: (NB! Remember to choose the correct architecture. (If allready present, please skip this step.))
[archlinuxfr] Server = http://repo.archlinux.fr/i686
[archlinuxfr] Server = http://repo.archlinux.fr/x86_64
- Install Opera using the latest snapshot:
# sudo pacman -S opera-snapshot
Vital that you have done the above, installed polymer and executed qtconfig. (Note that qtconfig can set your font to 6 when run multiple times.)
It should now function properly. If not, please use the talk section of this article.
