Summary: [945GM] [UXA] Running Out of Memory with UXA
Product: Mesa
Version: unspecified
Platform: x86-64 (AMD64)
URL: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-
video-intel/+bug/376092
OS/Version: Linux (All)
Status: NEW
Severity: major
Priority: medium
Component: Drivers/DRI/i915
AssignedTo: [email protected]
ReportedBy: [email protected]
When I run compiz, the cached memory grows continuously until the system
becomes unusable. I suspect this to be a memory leak.
I've found that this is related to UXA, KMS used or not, and happens with all
the driver versions I have tested:
-- The official Jaunty 2.6.1
-- The 2.7.0 from ubuntu-x-swat (launchpad)
-- The 2.7.99 from xorg-edgers (launchpad)
OpenGL version string: 1.4 Mesa 7.5-rc1 (happens with default Jaunty too)
X.Org X Server 1.6.0
This doesn't happen when using EXA or without compiz.
To reproduce:
Do some window open/close/resize/…
I use this bash line:
while true; do firefox & sleep 3; pkill firefox; done
You could see the cached memory grow quickly and about one minute after I'm out
of memory (on 1GB).
The attachments and details of how I investigated are on the original bug
report given as URL:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/376092
Summary:
This is neither related to architecture (both i386, amd64) nor (actual) kernel
version (Jaunty official / 2.6.30-rc).
The external monitor doesn't play any role here.
It seems that the leak go with the resolution, bigger screen, quicker run out.
I hope to be complete…
