Gnome System Monitor causes Xorg to consume 100% CPU

Posted by: Quail in Debian, Gnome, Howto, Xorg

With Gnome System Monitor 2.22 under Debian testing (Lenny) I had the problem when I clicked on the Resources tab the CPU usage would got to 100% on my laptop and desktop.

Well I have been able to fix the problem on my laptop which has and Intel video card by adding Option “AccelMethod” “EXA” to the Device section in my xorg.conf file.

Example:

Section "Device"
        Identifier      "Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller"
        Driver          "intel"
        BusID           "PCI:0:2:0"
        Option           "AccelMethod"  "EXA"
EndSection

When I have worked out how to fix the problem on my desktop using a Nvidia video card I will post the solution.

Thanks goes out to MistaED for pointing out to me that this a problem with the way Cairo rendering is done.

Turns out nvidia’s 2D accel went downhill due to init_mm() being taken out in the latest kernels which nvidia’s 2D accel must’ve depended on for memory management, I think kernel 2.6.24 was when this part was taken out

Oh the joys of accelerated X (or lack thereof)
