Hallo!

First of all I need to run

 

export DISPLAY=[my IP]:0


or all samples will end with a segfault!

With DISPLAY set I got it working for CPU devices, but I also have a HD4850 and I get a

 

ERROR: clCreateContextFromType(-1)


when trying to create a context.

-1 probably is CL_DEVICE_NOT_FOUND.

Additionally fglrxinfo only works with DISPLAY=:0

 

$ fglrxinfo

Error: unable to open display (null)

$ export DISPLAY=:0
$ fglrxinfo
display: :0.0  screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: ATI Radeon HD 4800 Series
OpenGL version string: 3.2.9239



The fglrx driver is setup properly.

 

$ glxgears
46713 frames in 5.0 seconds


Any suggestions?
