hi, thanks for posting the methods.
I tried the way of changing /etc/gdm/custom.conf and did not succeed.
If I understand correctly, by running remotely, you mean you can execute brook+/cal through remote ssh to the machine.
Right now, it seems that I should always use X windows to get my GPGPU applications to run even I do not need display at all. I know CUDA supports remote ssh without X windows.
Any other ways? Thanks
BTW: I use 4870 and CentOS 5 x86-64
