Description Tom Hunt 2012-01-27 05:32:43 UTC
Version: X.Org X Server 1.11.3.902 (1.11.4 RC 2)
Latest Git version of xf86-video-ati and 2 X Radeon HD3450 and 4 X Monitors.

It was required to run the lastest git version of xf86-video-ati to stop X from segfaulting on any opengl applications in my configuration.

After 24 hours of use X creeps up from 400MB Ram to 3GB of Ram every time and requires a restart to clear.

My friend is running an identical setup as me with same versions of code but only 3 monitors and all in a row. He does not have the memory Leak at all (Or at least it is not obvious)

I am not a valgrind expert but if someone could tell me how to generate a useful report then I am willing to try also any other information you might think to be useful.

Xorg.conf as follows:

Comment 1 Tom Hunt 2012-02-07 06:55:30 UTC
After some more research:

This happens with the Closed AND Open source ATI driver.
It happens on ARCH and Gentoo and also with 1.11.4 version of X Server.
Comment 2 Jeremy Huddleston Sequoia 2012-03-30 20:10:54 UTC
Can you please provide more information.  Can you use valgrind to find the source of the leak?
Comment 3 Jeremy Huddleston Sequoia 2012-06-12 03:51:55 UTC
No response.  Closing.
