Unhappy CPU usage 100%


Hello everybody,it's my first post because i like to solve problems myself,but now i'am really lost.When i try to move any open window cpu usage raises to 100%,i have celeron 1100Mhz,256ram and 32MB video,i really dont think that gnome is such a monster(Red Hat 9.0),i dont know there is the problem,i remember i had the same problem in Alt Linux,but it had a wonderful utility where you could set CPU priority to low,and then everything began to fly !!!,i miss that in Red Hat,please suggest what to do.

There's something wrong for sure...Please open a terminal and tun 'top' in it. It shows most processor and memory hungry processes. Then try to move any window. Please write which process uses so much power.

If you ever compiled a kernel youself try it with vanilla sources.I had a problem like that with patched sources and top wouldn't even show that CPU was at 100%.

Vanilla Sources...hmm,something interesting,i'll try that later,but now it could be good to solve this problem without compiling the kernel.

Just a shot in the dark:disable acpi or just check with top as Mara pointed out.Other than that please state your video wrangler and the drivers you use.

As Mara and crashmeister asked, what is the output of top. It will tell what apps or apps are using CPU cycles.

Check with the /etc/X11/XF86Config file if it uses the nvidia driver or the vesa driver.X should use about 0.5% of the Cpu while sitting around;not 45%.You can also try the nvidia driver from their website.

yes,the driver is nvidia ("nv"),what about the new ones,so i have them,but there comes another story,they require kernel-headers-2.4.20-20.9 for i686,i dont know why they are so rare because i cant find them,the most interesting thing that those floating windows became from fresh instalation,i really havent damaged my system,and is a native Red Hat 9.0 "nv" driver so bad ? p.s. even my mouse uses half processor resources when i am spining around with it.

well i have installed newest nvidia drivers without instaling kernel headers,kernel source was enough for them,the situation got better,but just better,kernel source which i have is i386 and the kernel is i686,maybe this is a problem too.The output of top now :

I doubt that the difference between the kernel source is a problem.You are still way too high with the CPU for X.Check the XFree.log in /var/log/ There might be some error messages that help.

now i really wish that /var/log/xfree.log had some error messages,but it hasn't,nobody tells me where is the problem,even logs look fine ,must be it's time to gather all information
,and try to compile a new kernel...

It should either be a problem with xfree or the kernel.Depending on which is less annoying with your distro I'd try another xfree version or a different kernel.
After all I consider myself as master of the known universe but I get it wrong once in a while,too
