I originallt posted this in the newbie forum, but since I didn't get any answers I'll try posting it here to. This was my original post.

I hope anyone can help me with this annoying problem. When I turned on my computer this morning and started KDE the window decorations were gone. That is, no buttons, no borders and so on. Just the content that is in the window is visible. So i tried rebootng the computer with an old kernel, and that helped. Things were back to normal. So my question is. Is there anything to do other than to recompile the kernel?

Could it maybe be the driver for the graphic card? It's an Nvidia 2 Go.

That was what I had experienced at that point.

Since i didn't get any replys, I just wiped the drive and re-installed Redhat. Now the same thing has happend again. Everything ran lika a charm. I updated my system with the Redhat network agent. However, after a fev re-boots, the same thing has happend again. The window decorations are gone. No buttons, no borders and so on. The system is also unable to log out the user. When logging out the screen just turns black and flickers every 2 seconds

first try looking into some logfiles (usually found in /var/log/) and try to search for what actually happens, when you try to log out a user. this may lead you to the reason of the problem....

if this is XFree-related problem, the result should be found in XFree86.x.log (where x is a number, usually 0 -> XFree86.0.log). And also see some other logs just in case...

first log in, then log out - now you said your screen starts flickering. try to switch to another console with, say, CTRL+ALT+F2. If you get it going, now read the logfile (problem should be visible at the end of the log?) with a command something like this:

cat /var/log/XFree86.0.log | less

and when you're done, hit q button. if you can't get the console open (screen flickers and won't do a thing), reboot and then read the logfile(s)...

this is, at least, a start

For some strange reason, my computer decided to start function normally again. Until the same thing happen again, I guess there's not much to do.

However, thanks for the suggestions. At least now, I know a little bit more on where to start looking if something similar happens again.

heh..well, that's weird..but hopefully your computer won't start doing the odd stuff again
