Description of problem: i have found an exact description of the problem here: http://ubuntuforums.org/showthread.php?t=1664467 this user describes the same problems i have. He is using ubuntu, im using fedora 14 i quote his description here "sometimes, X just freezes on me. It's not a total freeze because I can move the mouse pointer around, but the desktop is unresponsive. However, I can VT-switch and work from a shell without any problems. Upon examining the running processes in top, nothing seems out of place. No single process is hogging CPU or memory, system load is good, everything looks fine. I've checked all of the system logs, Xorg's log, and the .xsession-errors log. Nothing wrong that I can tell. Whenever I VT-switch back to X, I can still move the mouse pointer around, but still the desktop doesn't respond. I've found that I can restart X (sudo /etc/init.d/gdm restart), but this of course means I lose all my windows in X. X restarts just fine, but the system seems a little unstable to me. For instance, pulse audio doesn't always seem to work. A reboot clears everything up, however. Now for the trigger. I can't figure out what causes the freeze! At first I thought it was Flash locking up on me, but I don't think that's the case anymore. Then I noticed it seems to happen more when I use Google Chrome than Firefox. Finally, I've tried disabling Compiz for over a week and the bug has not showed up. As soon as I re-enable Compiz and spend five minutes with Chrome, then I have this X freeze. It seems to me that it usually happens when I'm in the middle of scrolling a page in Chrome. But it seems to happen at other times, as well. I can't seem to reliably reproduce the bug." the same behaviour happens to me, but if i do multiple vt switching sometimes the keyboard does not work anymore so i have to kill X the first time i vt-switch... Im using a t60 laptop by lenovo with X1300 video card. Version-Release number of selected component (if applicable): How reproducible: have a laptop with a X1300 video card, enable compiz... wait Steps to Reproduce: 1. 2. 3. Actual results: i have to kill Xorg Expected results: Xorg is stable using compiz Additional info:
for additional info, i have already pointed out (in a previous ticket which i have closed because part of my diagnosis was erroneus) that the radeon module, when it's loaded, sees the video card with 128 MB of VRAM, with sounds odd to me: ... [ 1.564084] [drm] Initialized drm 1.1.0 20060810 [ 1.608537] [drm] radeon defaulting to kernel modesetting. [ 1.608541] [drm] radeon kernel modesetting enabled.

Maybe the "compiz issue" is related to having a wrong VRAM in the readeon module... I own a desktop which is very close to my laptop (it uses RV530 instead of RV515) and the issue doesnt exist... in that case the video card has 256 MB of video ram and during the radeon module modprobe the amount of detected memory is VRAM=BAR=256M...
This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.
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 add drm.debug=0x04 to the kernel command line, restart computer, and attach * your X server config file (/etc/X11/xorg.conf, if available), * X server log file (/var/log/Xorg.*.log) * output of the dmesg command AFTER the lockup (but before reboot), and * system log (/var/log/messages) to the bug report as individual uncompressed file attachments using the bugzilla file attachment link above. We will review this issue again once you've had a chance to attach this information. Thanks in advance.
Reassigned to mesa as this is clearly a video driver issue.
does putting radeon.msi=0 on the command line help?
This message is a notice that Fedora 14 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 14. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At this time, all open bugs with a Fedora 'version' of '14' have been closed as WONTFIX. (Please note: Our normal process is to give advanced warning of this occurring, but we forgot to do that. A thousand apologies.) Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, feel free to reopen this bug and simply change the 'version' to a later Fedora version. Bug Reporter: Thank you for reporting this issue and we are sorry that we were unable to fix it before Fedora 14 reached 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, you are encouraged to click on "Clone This Bug" (top right of this page) and open it against that version of Fedora. 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
