Description of problem: ati modesettings cause negative performance impact to system. Even sound notifications in KDE are faltered. Text scroll is ugly slow. Version-Release number of selected component (if applicable): kernel-2.6.27.4-79.fc10 Additional info: If pass nomodeset to kernel - sound is much better, text scroll is much faster Is any additional info needed?
I can second this. I have an hp pavilion dv8000 laptop w/ ati xpress 200m. With nomodeset text scrolling and performance is amazing. With kernel modesetting it is slow as molasses.
same problem here. With modesetting, the system is really slow (even music in rhythmbox jumps...and I've an athlon X2 @ 3ghz...) glxgears reports 500 fps with nomodeset, better situation.... but is not fast... (amsn really slow, high cpu usage in moving windows) glxgears reports: 1500 fps in f9 glxgears reported 2800/3000 fps I noticed NO performance increase (and it's REALLY strange) using this settings: Option "AGPMode" "8" Option "RenderAccel" "on" Option "XAANoOffscreenPixmaps" Option "ColorTiling" "on" in xorg.conf... usually agpmode 8 gave me a great speed boost.... but I tried both with and without these setting...NO CHANGE... it looks like are ignored.. I updated some system pieces with no results: xorg-x11-drv-ati-6.9.0-51 xorg-x11-server-1.5.3-5 No speed boost.. just a more stable environment.
Noticed the same issue, but didn't think to report it since I'm having multiple issues with the ATI Xpress 200M, the latest being a lockup which is reported in 472634 - which appears to have been introduced by xorg.x11-drv-ati-6.9.0-54.
Looks like all my issues can be traced by to using radeon.modeset. I'm now using the "nomodeset" parameter and all appear to be circumvented.

Additional info. I use radeonhd driver for ATI X1250 (AMD 690G), because it's slow but stable. With modesetting on + default radeon driver I have kernel level crash within 1-2 minutes, with nomodesetting + default radeon driver after 30 mins. I have no crash with modesetting + radeonhd, but it's really slow. Changing between windows takes 1 sec at least.
This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle. Changing version to '10'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
I'm having this problem too. ATI RS480 + ATI X700 (R420), Ferrari 4000 laptop (x86_64) (More details can be provided..) Using kernel modesetting slows the system down considerably. It also causes resuming from a suspend cycle to fail, and enabling "desktop effects" causes a hard hang, but those are different problems.
Can you test with fedora 12 livecd and report if it works with it.
This message is a reminder that Fedora 10 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 10. 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 '10'. 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 10'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 10 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: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
