Opera

Opera is a full-featured web suite by Opera Software ASA, a Norwegian IT company. It is closed-source software, but I prefer to say it is "free as parking".

[edit] Why should I use Opera?

  • It's fast and lightweight.
  • It's standards-compliant.
  • It's very much 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.

[edit] Why should I NOT use Opera?

  • It is not Free. It's proprietary software.
  • It's a Qt application, which means it requires loading additional libraries if you're not running KDE.
  • Some webpages don't display correctly because they are not following the web standards (Opera sticks to standards).

[edit] How do I install Opera?

To install the latest stable Opera: 

# pacman -S opera

If you don't want Opera 9.5 to use Qt3, but Qt4 instead, you can install opera-devel-qt4 from AUR.

[edit] 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 kind look bad. 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

[edit] Optional tweaks

  • 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

[edit] Troubleshooting

  • 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)
