Notes

The best solution/workaround I found is to create an executable script (eg: start_firefox) with the following lines (1, 2):

#!/bin/sh
export LD_PRELOAD="/usr/lib/libGL.so.1"
/home/alexb/apps/firefox/firefox
chmod +x start_firefox
./start_firefox

Another solution is to disable the hardware acceleration in Flash (probably a bad solution):

1. Right click on the embedded Flash window inside Firefox (flash video)
2. Settings…
3. go to the first tab
4. un-check “Enable hardware acceleration”

Now you should be able to go full screen…

Here is the version of the software I was using.

• Flash v10,0,15,3
• Firefox 3.0.5 and 3.5.2
• NVIDIA video driver 180.22
• Kernel 2.6.27.7-smp

…DOOM 1, a 15 year old game converted to flash, is jerky on a fairly recent computer.

It’s still worth a try, play now.
