That's strange. Have you tried the open source radeon driver? The 128MB PCI Express x16 ATI Radeon X800 SE works OK here with radeon driver for dual head and 1920x1080 on both. I did a writeup here: http://www.penlug.org/twiki/bin/view/Main/LinuxHardwareInfoATIRadeonX800 I would have thought the X800 XL 256 would be better than the X800 SE. Cheers, Peter.
