Classification: openSUSE Product: openSUSE 11.2 Version: Final Platform: i686 OS/Version: openSUSE 11.2 Status: NEW Severity: Major Priority: P5 - None Component: X.Org AssignedTo: bnc-team-xorg-bugs@forge.provo.novell.com ReportedBy: laurent@nodrahc.com QAContact: xorg-maintainer-bugs@forge.provo.novell.com Found By: --- Blocker: --- Created an attachment (id=339846) --> (http://bugzilla.novell.com/attachment.cgi?id=339846) Xorg.0.log User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1.6) Gecko/20091201 SUSE/3.5.6-1.1.1 Firefox/3.5.6 Using kdm and KDE with OpenSuse 11.2 upgraded from 11.1, upgraded from 11.0 etc... When two users are logged in KDE via the switch user method, the desktop that is in the background will eventually eat up all the cycles of one CPU. It doesn't happen right away but after a few minutes delay. I think it is related to when the screen saver on the non-visible desktop would have started. Or it could be when the power saving mode is "entered" on the non-visible desktop, I am not sure. In any case it's a big problem for a laptop. Visiting the stuck desktop with CTRL-ALT-F8 and back with F7 cures the problem momentarily but it comes back again after a delay. The screensaver on all accounts is "blank", so the problem is not with openGL or similar. Here is a few lines from top: top - 10:19:32 up 1:24, 5 users, load average: 1.16, 1.25, 1.21 Tasks: 169 total, 2 running, 166 sleeping, 1 stopped, 0 zombie Cpu(s): 8.1%us, 44.7%sy, 0.0%ni, 47.2%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 3060628k total, 1580744k used, 1479884k free, 61624k buffers Swap: 4072468k total, 0k used, 4072468k free, 1010784k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 6726 root 20 0 192m 51m 5232 R 98 1.7 30:53.89 Xorg 1471 root 20 0 387m 58m 7940 S 2 2.0 3:26.13 Xorg Reproducible: Always Steps to Reproduce: 1.

You're using the radeon driver for Radeon X1400. Does this issue als occur when using radeonhd driver (which is our default)?

I tried the ati driver and it does the same thing. The radeonhd driver does not work with my card (X1400) -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The ati driver loads the radeon driver, so that's no new information. X1400 is supported by radeonhd driver. If there are issues with that support, that would be worth being reported.

OK, I managed to get a newer radeonhd working (this one: http://download.opensuse.org/repositories/X11:/Drivers:/Video/openSUSE_11.2/...) I have the same issue with radeonhd, plus a few more. I will file a separate bug report for those other issues. I tried the vesa driver as well, same problem. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I think it's best to keep the bug open as far as it's not confirmed to be fixed. This might help to reduce the number of new duplicates (searching for a closed bug is usually not done by default). Please correct the whiteboard content I am adding if inadequate.
