Testing major GEM memory leak

Recently in Lucid, a major memory leak was introduced into the X.org server which causes the computer to get slower and slower over time. This is reported as bug 565981.

One possible solution is to roll back the GLX 1.4 enablement patches, and the patch which caused the memory leak to appear.

Installing the test packages

Please do the following to upgrade to the proposed X server with the fix:

•   sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
    sudo apt-get update
    sudo apt-get dist-upgrade

After that, reboot and log in.

Testing

Please work with your system normally for a few hours (at which point the current lucid X.org server should feel really sluggish), as well as check functionaly and performance of:

• Video playback (fullscreen and windowed)
• Games (extremetuxracer, sauerbraten, etc.)
• compiz (quickly change desktops and move windos around)
• Flash movies
• etc.

Please verify that glxinfo | grep "GLX version" says "1.2", not "1.4".
