Description of problem: When a process use a lot of cpu time (compiling, using yum, ...) the system is very slow. The move of the cursor in X is very slow and the computer is unusable. This problem did not exist with FC-6. Version-Release number of selected component (if applicable): 2.6.21-1.3228.fc7 but it was the same with older F7 kernels How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: System slow as the task repartition is not good. Expected results: System usable. Additional info:
In fact, disabling desktop effects make this problem disapeared. So i reassign this bug to compiz.
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 file (/etc/X11/xorg.conf) and X server log file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file attachments using the bugzilla file attachment link below. Could you please also try to run without any /etc/X11/xorg.conf whatsoever and let X11 autodetect your display and video card? Attach to this bug /var/log/Xorg.0.log from this attempt as well, please. We will review this issue again once you've had a chance to attach this information. Thanks in advance.
It's a long time since this bug is open. This problem does not exist anymore in F8 and i don't have anymore a F-7 computer.
Thanks for letting us know and sorry for the delay. Working on clearing the que, so it should not happen any more.
