I've the NVIDIA driver on two machines, one a TNT2 M64 the other a GeForce 256.
On the TNT M64 machine, when switching virtual screens using Ctl-Alt-F8 (e.g., running two X servers) the screen goes blank as usual, but then stays that way permanently! The whole machine is locked, keyboard and all. The only solution seems to be a power cycle. This has also happened when running some of the GL screen savers in xscreensaver. Using the "nv" driver from XFree86 I have never had this problem. Normally when switch virtual screens the current screen goes blank, the monitor momentarily looses the signal, then the new screen comes to life! This seems to normal behaviour. On the GeForce machine I only run a single X server and have not seen this problem, although exiting from the evas_test program from the evas-demo package crashed the X server. Cheers, Graham
