I running Redhat 8 with kernel 2.4.18-19, and installed a nvidia driver by source. The card is a RIVA TNT2 M64.
Now X starts up just fine, and I assume that the hardware accel and openGL are working as the "gears" demo runs very nicely but when I try to run other openGL apps the screen goes completely blank. It almost sounds like it has switched to a different screen mode - the click and hiss of static?
At this stage the screen res <ctl><alt><+> or <-> does not help, nor does switching apps or windows. There is simply nothing left to do but reset the machine.
