Along with the possiblility of "bad" video drivers, you might also want to consider a "hardware" problem. I recently experienced similar behaviour when I put KDE on a bare-bones DEC Alpha machine with 64 Megs of memory. (This is equivalent to 16 or 32 Megs in a i386 machine.) In my case, it appeared that the system was doing a LOT of disk-swapping to the swap file, but I never could see the swap partition being accessed. Someone mentioned that it might be due to some excessive memory page swapping. The symptoms disappeared when I upgraded the memory to 256 Megs. In your case, 128 Megs of memory should be sufficient (I have a i386 machine here running KDE with that amount), BUT if something is wrong with your current memory stick and the machine is NOT "seeing" all 128 Megs, then you could be pushing it a bit. One thing I noticed on my DEC Alpha, is that GNOME would run OK, but KDE wouldn't. This lead me to initially believe it was a KDE software problem, but it wasn't! The "problem" was that KDE required more memory to work than GNOME. You might try firing up GNOME (if you have it installed) and see if it happens there. This might help you narrow down the "problem" a bit. Cheers, -Don Spoon-
