Hello, I am using F10 with KDE 4.1, using nvidia-173xx driver (the older nvidia driver, I think). My graphic card is GE Force FX 5500 AGP (rather old). I use some 3D effect in KDE. I use both the DVI and VGA output from the card with Twinview option. The problem is : 1. rather frequently the desktop would lock up for few seconds. Sometime when this happens, I can move around my mouse pointer but not do anything else. The mouse pointer becomes a block of glitchy display that moves around. On other instances, it would just lock up and not accepting any input. 2. Once in a while the whole screen would blink with a blank screen, then comes back to normal. When these things happen, I don't usually do anything fancy (i.e. not switching / moving Windows with 3D effect or anything like that), just simply typing on terminal or document. When (1) happen, the OS itself is still running. I can workaround the lock up by switching to TTY (CTRL-ALT-F2), then switch back to X again. That almost always clears the lock up, although sometime it takes a second or two before CTRL-ALT-F2 gave me TTY. So, my question is, is there a known problem with either the Nvidia driver, or KDE, or the combination of both ? Or, am I simply having a bad graphic card ? Any suggestions to find out ? Thanks.
