As it says, your driver tells me to contact you. This is a Dell XPS210, radeonhd does not handle the on-board (secondary, disabled) device. lspci (relevant parts): 01:00.0 VGA compatible controller: ATI Technologies Inc RV516 [Radeon X1300/X1550 Series] 01:00.1 Display controller: ATI Technologies Inc RV516 [Radeon X1300 Pro] (Secondary) lspci -v (relevant parts): 01:00.0 VGA compatible controller: ATI Technologies Inc RV516 [Radeon X1300/X1550 Series] (prog-if 00 [VGA]) Subsystem: Dell Unknown device 0d02 Flags: bus master, fast devsel, latency 0, IRQ 16 Memory at c0000000 (64-bit, prefetchable) [size=256M] Memory at dfde0000 (64-bit, non-prefetchable) [size=64K] I/O ports at dc00 [size=256] Expansion ROM at dfe00000 [disabled] [size=128K] Capabilities: [50] Power Management version 2 Capabilities: [58] Express Endpoint IRQ 0 Capabilities: [80] Message Signalled Interrupts: Mask- 64bit+ Queue=0/0 Enable- 01:00.1 Display controller: ATI Technologies Inc RV516 [Radeon X1300 Pro] (Secondary) Subsystem: Dell Unknown device 0d03 Flags: bus master, fast devsel, latency 0 Memory at dfdf0000 (64-bit, non-prefetchable) [size=64K] Capabilities: [50] Power Management version 2 Capabilities: [58] Express Endpoint IRQ 0 Attached is the Xorg.0.log when failing, the xorg.conf used, the conntest output for primary and secondary card, just tell me what you need and I'll fix it. It is a bit troublesome that radeonhd shuts down with an error even though it is only the secondary (non-used) card that is unidentified. Yours, Linus Walleij
