Red Hat Bugzilla – Bug 486368
ATI radeon very slow - almost unusable
Last modified: 2009-03-08 06:33:19 EDT
Description of problem: F11 / rawhide on my system is so slow that it is almost unusable and I must consider giving up trying to test it. To me that is a serious regression in a serious component and I have set severity/priority to indicate that. I dont' know where the slowness comes from, but it is visible that for example redrawing after switching windows is slow, so I assume it is related to the X driver. I have seen other reports which might be similar to this one, but I haven't found anything conclusive, so I create this issue to track my issue and my uploads without confusing by mixing them with what other see and report. Version-Release number of selected component (if applicable): kernel-PAE-2.6.29-0.124.rc5.fc11.i686 no KMS as mentioned on bug 486327 xorg-x11-drv-ati-6.10.0-3.fc11.i586 no xorg.conf 01:00.0 VGA compatible controller: ATI Technologies Inc RV516 [Radeon X1300/X1550 Series] .xsession-errors has a lot of other noise, but the only X related is: Xlib: extension "XFree86-Misc" missing on display ":0.0".

Similar to bug 486049 . Keeping both because of different hardware (RV516 vs R420).
My notebook with a Mobility Radeon 9200 M9+ (R280) certainly feels a lot more sluggish under F11 than it did under F8 or F9 with 2D and no desktop effects (glxgears gets around 1200 fps), this is using kernel-2.6.29-0.137.rc5.git4.fc11.i586 and xorg-x11-drv-ati-6.10.0-3.fc11.i586, with no xorg.conf. Should I report a separate bug for this?
I think you could wait for 6.11.0 and check again. It feels a lot faster on RV350.
I see no improvement with the 6.11.0 driver.
This seems to be indeed a widespread regression. Just to recapitulate from: https://www.redhat.com/archives/fedora-devel-list/2009-February/msg02329.html related bugs might be: bug 485651 bug 469577 bug 485275 bug 486049 maybe also in some way bug 242386 There are lot of affected users, adding as F11Blocker.
(In reply to comment #7) > This seems to be indeed a widespread regression. Just to recapitulate from: > > https://www.redhat.com/archives/fedora-devel-list/2009-February/msg02329.html I tried dropping the patches from the SRPM as suggested, but saw no significant performance increase on my Mobility Radeon 9200. Hmm. There are an awful lot of things like Xorg:2269 freeing invalid memtype ea102000-ea112000 in the syslog after quitting X.
It works fine for me now, both with and without KMS, thanks! xorg-x11-drv-ati-6.11.0-3.fc11.i586 kernel-PAE-2.6.29-0.203.rc7.fc11.i686 Closing
Hmm... the 2D side of X is still sluggish on my M9+ system. At the login screen, for instance, the background doesn't fade in smoothly at all (~1 fps). This is with kernel-2.6.29-0.207.rc7.fc11.i586, xorg-x11-drv-ati-6.11.0-5.fc11.i586 and mesa-dri-drivers-7.3-10.fc11.i586.
