Recently we installed 3.3 on a 280-GTX. I have tried porting a graphics program (which had been originally developed under 3.2) over to this new machine, and recompiled it on the 3.3 machine. This program's purpose is to display a GIF-format image in a NeWS window on the graphics console. However, for unknown reasons, this program blanks out the graphics screen entirely and won't respond to any console input. Trying to telnet in from elsewhere, one is unable to kill either the graphics process itself or the graphics console daemon (even as root -- I tried everything). To regain control over the machine again you actually have to do a hardware reset! A look at SYSLOG suggests that it has something to do with the graphics FIFO getting filled up. However, this never happened under 3.2 (and in fact the 3.3 machine I ported to had four times as much memory). Is there any simple reason this might happen? Would it be specific to the graphics calls that I make in the program? I haven't been able to really delve deeply into the 3.3 graphics docs, but so far in my reading haven't come across anything that helps me on this. Any suggestions? If so please send me e-mail (cliff@research.nec.com -- also replying to this address at phoenix will work). Thanks! --Cliff Clifford B.
