Opera

Installing Opera on test machines is easy. From a shell, run these commands as root:

wget ftp://ftp.opera.com/pub/opera/linux/910/final/en/i386/static/opera-9.10-20061214.1-static-qt.i386-en.rpm
rpm -vi opera-9.10-20061214.1-static-qt.i386-en.rpm

This installs version 9.10. To learn about the most recent builds of Opera, check the Opera desktop blog and select the statically linked rpm packages for Unix/intel-linux.

Opera is more than a web browser, it's also an RSS and Atom feed reader, bittorrent client, email client, and IRC client.

Opera offers keyboard shortcuts that may come handy:

• q/a navigates up/down in links
• w/s navigates up/down in headings
• 9/0 zooms page out/in

To execute Opera inside X-Windows (Sugar), you need to:

• As root, go to a shell and set an environment variable:

export DISPLAY=127.0.0.1:0.0

• Execute the opera with the user olpc:

su olpc -c "opera &"

Known problems

• Running certain scripts inside Opera causes the machine to freeze. To avoid this, you can turn off JavaScript in the (quick) preferences (keybinding F12). Here is a minimal test case that exposes the problem:

<script type="text/javascript">
 var d = new Date()
 d.getMilliseconds()
 document.write(d)
</script>

• Fullscreen isn't quite fullscreen, there's a gray bar at the bottom
• Widgets are not yet usable
• Opera is not integrated into the Sugar UI
• Due to the high pixel density, one "px" should probably be mapped to two pixels. Opera currently does not do this. It helps to set opera:config#UserPrefs|ForceDPI to 200 and restart Opera.
