Hi, I’m setting up CUDA 5.0 on an Ubuntu 12.04 headless server… Initially, GPU 0 was crashing almost instantly, which was probably caused by conflicts with the EFI frame buffer device… Adding:
video=vesa:off video=efifb:off vga=normal
to the linux commandline seems to solve the problem. However, I still see these message in dmesg:

Is this warning about the system not being configured to drive a VGA console something I should worry about?
I don’t see it appearing on our older servers running the same configuration.
