Linux performance suddenly very slow


Hi,

I'm not sure when this started, and I have no idea what could have triggered it. I first noticed some graphical glitches in the XFCE window decorations, though these may not be related. Then I noticed that I was unable to run any games or play movies in full-screen at tolerable speeds. I decided to run glxgears, and I'm getting a framerate of around 500! I've checked, and I definitely have 3D acceleration on and functional. But for some reason, performance is now terrible. At first I thought it could be a hardware problem, but when I booted into Windows everything ran perfectly, even 3D accelerated games. Does anyone have any idea what could be causing the sudden slowdowns and graphical glitches? Are there any methods I could use to locate what exactly is causing the problem?

Thanks.

Did you get a new version of xorg? Graphics drivers? The kernel? Anything?

you have to look at tasks in a monitor and try to figure out what is hogging cpu cycles
if the desktop saves session there can be a saved runaway process that keeps getting restarted or
sometimes some bad network settings can cause constant cpu confusion
the possibilities are endless
also check error logs and see if there is an error repeating endlessly

I fixed the window decorations; it was an unrelated problem. It turns out that the problem must have been with X.Org, because the problem disappeared when I switched back to XFree86. There must have been something wrong with this specific version of Xorg, as I've used it before without problems. Oh well, that's what I get for running Debian unstable.
