Hi there, i'm trying the radeonhd driver (today git version) on my system but my card seems to be not recognized. My card is a Radeon X1650 XT (PCI-E) and works fine with the avivo driver. As suggested in the xorg logs i'll try to provide you with the information needed. In the attachments you will find the xorg log with the radeonhd driver, the one with the avivo driver (maybe could be useful) and the output of the conntest tool (also with the VBIOS dump). Some other information of my system: Kernel: Linux 2.6.22.4 SMP PREEMPT x86_64 GNU/Linux Distribution: Debian/sid up to date Xorg: 7.3 Card: 01:00.0 VGA compatible controller: ATI Technologies Inc Radeon X1650 XT (Primary) (PCIE) (prog-if 00 [VGA]) Subsystem: ASUSTeK Computer Inc.
