bug

In our Ubuntu 10.04 LTS Lucid Lynx Release Candidate post, we were telling you about a major X.Org Memory Leak bug. Well, apparently the bug has been fixed and an update was released.

The bug has not been confirmed as fixed by everybody testing so it will be interesting to see if there are still computers affected by this bug.

Besides the X.Org Memory Leak bug (marked as critical), 2 other bugs were fixed with this update: #565903 (medium) and #550218 (high).


Unfortunately, fixing these bugs also means going back to GLX version 1.2 (instead of 1.4).


What exactly did the bug do? It was causing the computer to get slower and slower over some hours, and finally becoming totally sluggish. That's because closing an application didn't free up the memory.

The bug didn't affect cards using proprietary drivers or not using DRI2 because it is specific to the glx module that the open drivers use. Intel will always be affected since DRI2 is used with and without KMS, ATI uses DRI1 without KMS.


Are you using Ubuntu 10.04 LTS Lucid Lynx? How is everything working for you?
