Xorg log

Description of problem:
After I upgraded (with yum upgrade) from F11 (all updates) to F12, X started being very choppy, especially with window movements, etc.  It's not clear to me whether this is an Xorg base, Xorg drivers or some other issue.

Version-Release number of selected component (if applicable):


How reproducible:
Start X. Open some windows (e.g. Firefox), move them around, minimize/maximize, move mouse pointer between windows, etc.

Additional info:

From /var/log/rpmpkgs* I note that prior to F12 upgrade, I was using xorg-x11-drv-radeonhd-1.2.5-2.10.20090714git.fc11.i586 which is a bit older.

After the upgrade, the fonts used by (at least) Firefox changed -- they looked better (anti-aliasing?).  This may be relevant.

Typical CPU usage when completely idle is usually between 20-30%. If I move my mouse pointer quickly between two open firefox browser windows, this reliably drives up the Xorg CPU consumption to over 90%. Automatic window refocusing (without clicking) is enabled.

The system is almost unusable with this CPU consumption.

Update: I also tried  xorg-x11-drv-radeonhd-1.2.5-3.14.20090918git.fc12, no difference.

I set radeon.modeset=0 when booting, the usability was restored.  Steady state Xorg CPU is 6-7% and I can get it (only) up to 38% but no higher by fast-moving mouse pointer between windows.

This worked for me too, which is good, because in addition to the desktop being messed up six ways from Sunday, the textures in openarena were. . .interesting.  All is totally fine on the radeon driver with radeon.modeset=0.

This message is a reminder that Fedora 12 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 12.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '12'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 12's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 12 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:

radeonhd is no longer provided in later Fedoras, having been substituted.
