glxgears produces the following output:

Using GLX_SGIX_pbuffer

GL_RENDERER   = AMD Radeon HD 6990

GL_VERSION    = 4.1.10750 Compatibility Profile Context

GL_VENDOR     = ATI Technologies Inc.

Xserver is running

Well, looks like its now down to some sort of permissioning issue. After one of the latest reinstalls, I am able to get clinfo to detect the cards, but only when run as root.

if you connect remotely via SSH you must first export DISPLAY=:0 of COMPUTE=:0 and you must have permision to access running Xserver session.

Originally posted by: mjhorn I've tried the driver install both through ubuntu repositories (apt-get install fglrx) as well as downloading the ati installer and running it as you have described. 

 

I agree at OpenCL seems installed correctly since it detects the CPU. However, if it were a Catalyst driver issue, wouldn't commands like fglrxinfo, or aticonfig --lsa not see the card correctly? Both do report the card, and I am able to use the card to display video if I actually attach a monitor. 

 

Thanks to both of you for your help so far.

 

I suggest to have a look at the installation guide of the fglrx driver on this link, it may resolve all your problem...
