 Posted: Fri Jun 20, 2008 6:12 pm Post subject: X monopolizes cpu after unlocking screen [SOLVED] |
 |
|
I know I've seen this before, but mostly associated with new drivers (e.g., nvidia), and I wanted to see if many have the same experience regardless of video hardware and driver. I have a Gigabyte GA-G33M-DS2R mb with integrated Intel GMA 3100 video, and after some period of inactivity I often return to find X has basically taken over the cpu, and effectively hung the display. At the console, I can unlock the screen, but that's as far as I get. The machine is not hung per se, as karamba scripts continue to execute and update the screen, and I can ssh in remotely (hence the top display below), but console access is pretty much gone. Kernel version is 2.6.24-gentoo-r8. I have no real screensaver active, just screen-locking enabled. Does anyone have any ideas what causes this? | Code: | Cpu(s): 55.2%us, 0.5%sy, 0.0%ni, 44.3%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st

(EE) Failed to load module "wfb" (module does not exist, 0)
(EE) intel(0): [dri] DRIScreenInit failed. Disabling DRI.
(EE) AIGLX: Screen 0 is not DRI capable |
Any ideas?

It's likely superkaramba:

I had the same issue when running more than one theme - only running one solved it for me but not everyone. Tons of comments on that bug. |

Thanks for the link, zBrain. The commentary and contentious back-and-forth are interesting to read, but it's still unclear where the bug resides: kde, SK, xorg-x11, etc. Will try running no more than one SK theme, as you suggest, and post back. Thanks again! |

Forgot to post back  , but that was it: more than one theme and it's going to hang. Thanks zBrain for your help.

Ah yes, superkaramba; nice looks, lots of bugs, resource hog. Yep, I remember it well.
Blessed be!
