I am work on cent 5.0 and using ssh to work on the computer remotly. I use the command export DISPLAY=:0.0 to set the server to use the video card on the computer I am doing research on to use its own video card for the stream computing and not the one on my terminal computer.
It worked well for a while then it stopped seeing the CAL device. When I logged onto the computer its self I found that it was using :0 for the DISPLAY and not :0.0 that my brook programs are looking for.
Does any one know why the computer is setting the video card to :0? And how to get it to go to :0.0 so I can continue to work remotely.
