Hello,
I have a Red Hat Linux release 9 (Shrike) machine with XFree86 4.3.0 installed. There are two partitions in my machine, root partiton is 1GB and it is 100% full, another partition size is 17G it is 4% full. df -h shows this....

[root@pluto root]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/hda1 1012M 992M 0 100% /
/dev/hda3 17G 571M 16G 4% /buildsys

If I leave the system IDLE for more than 5 or 6 hours the X Window performance becomes very slow, when I move the mouse pointer and if I try to click on some icons it responds very slowly. This happens whenever I leave the system IDLE for a long time(I wont shutdown this machine most of the time). If I keep using the machine there is no problem.

Is it because of my root partition(it is 100% full)? My swap partition size is 50M.

I am trying to find out the exact reason for this slow response. Now I am trying to run XFree86 with high priority using the "nice" command. I hope it can solve the problem.

Any other idea guys?

Thanks
Seran

probably if it's trying to write /tmp files.

I don't think it's a good idea to have 100% full partitions.

Still my root partition is 100% full. If I continue using my system there is no slow response from the X server. If I leave it IDLE for some time then only this delay in response happens.

Because you need to free up some space on /

A *nix system cannot fully function correctly when there is zero space left. Free out some tmp files in /tmp and possibly clean out some logs in /var/log

Remove any other necessary files you might not need in /home and other locations.

And this would or should give you a good reason to create separate partitions for /, /usr, /home, /var and /tmp at the minimal.... so if /tmp gets filled with temp files, it doesn't affect your whole system..
