The following error message is coming up.....
RADEON(0): GPU accel disabled or not working, using shadowfb for KMS
Graphics card is a Radeon 5870, works OK on FGLRX
I have a custom compiled kernel (3.2.9 also 2.6.39.1 has the same error) but the supplied Debian kernel does the same thing.
I have chased through all the docs including the radeon Build howto and as far as I can see it should be working. Help on the next step most apreciated.
I start to a console then run startx, kernel correctly sets console to 1920x1200, the following is part of the output of dmesg
