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. This does not affect cards using proprietary drivers or not using DRI2. Intel will always be affected since DRI2 is used with and without KMS, ATI uses DRI1 without KMS.
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 with compiz enabled (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 windows around)
- Flash movies
- etc.
Please verify that glxinfo | grep "GLX version" says "1.2", not "1.4".
Reverting back to lucid packages
sudo apt-get install ppa-purge sudo ppa-purge ppa:ubuntu-x-swat/x-updates

Apparently nvidia driver bypasses xserver glx, so not good testcase (works ok though) |

Updating to the xserver in x-updates on this machine fixes the problem where clutter based apps (such as gnome-games) fail to start when using Software Rasterizer (bug: 561734) |

Using the following from the bug shows that gem objects are increasing, but not X memory: pid=`pidof X` ; for t in `seq 1 10`; do eog /usr/share/backgrounds ; echo `grep "object bytes" /sys/kernel/debug/dri/0/gem_objects` `ps ocomm,vsz,rss $pid |grep X`; done |
