I am attempting to run GPU computation software on Ubuntu Server 12.04 without X since this box is going to be a dedicated computation machine. However the last requirement "Without X" is proving to be very problematic.
I have a ATI Radeon HD 5770 hooked up right now. Installed the x64 drivers from AMD's website by having it generate the correct debian packages. Ran
sudo aticonfig --initial --adapter=all and rebooted. However it doesn't seem like its working
adam@adamcrunch:~$ DISPLAY=:0 fglrxinfo Error: unable to open display (null) adam@adamcrunch:~$ sudo aticonfig --list-adapter * 0. 01:00.0 ATI Radeon HD 5700 Series * - Default adapter
My software is also having issues as it just won't use the GPU for computation and tries to use the CPU.
I know during my initial install with Xubuntu that the card works and I can do GPU computation on it. However is it possible to do it on a headless server without X?
I can provide more information if needed
