When I upgrade to the kernel-PAE-2.6.29-0.124.rc5.fc11.i686 and kernel-PAE-2.6.29-0.131.rc5.git2.fc11.i686 the display performance became sluggish. I assume this is cause by this kernel mode setting: * Mon Feb 16 2009 Kristian Høgsberg <krh@redhat.com> - Flip the switch on intel KMS. This is on a Thinkpad X60.
I have verified that disabling mode setting via nomodeset kernel option makes this problem go away.
Same here. Running with nomodeset, top shows ~320 MB allocated virtual memory - running with modesetting enabled, this increases to ~2000 MB. I'm seeing this on a Toshiba Netbook with Intel 945GM Chipset.
The issue seems to be chipset-specific - on a 2nd machine with a G35 chipset kms works smooth and without issues. Working: 00:02.0 VGA compatible controller: Intel Corporation 82G35 Express Integrated Graphics Controller (rev 03) Broken: 00:02.1 VGA compatible controller: Intel Corporation Mobile 945GME/GMS/GME, 943/940ML Express Integrated Graphics Controller (rev 03)
Thanks for the bug report. We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue. Please attach your X server config files (/etc/X11/xorg.conf, if available) and X server log files (/var/log/Xorg.*.log) from running both with and without nomodeset setting on to the bug report as individual uncompressed file attachments using the bugzilla file attachment link below. We will review this issue again once you've had a chance to attach this information. Thanks in advance.

I see this (Thinkpad X60s / 945GME), and yes, I do run a PAE kernel. Xorg.0.log attached.

Nope. The working one is running x86_64, broken is running a 32-bit PAE-Kernel.

I attached the Xorg.0.log with and kernel mode setting on and off. 00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03) I am currently running kernel 2.6.29-0.137.rc5.git4.fc11.i686.PAE It looks like Xorg memory usage goes way up as soon as I open several firefox windows.
There is no xorg.conf for this machine it is being completely autogenerated.
This seems to be fixed in the latest rawhide. xorg-x11-drv-intel-2.6.0-10.fc11.i586.
