Hi, I am install archlinux on my laptop, and I can't get my graphical card to work (Xorg doesn't start). My card is an ati hd 6750 I've installed xf86-video-ati, xorg-xserver and xorg-xinit. But when I try to run startx, xorg doesn't start, and I get a fatal error: no screens found. Here is the full Xorg log: http://renevier.net/tmp/Xorg.0.log.txt I tried to use catalyst as described on the wiki, but when trying to run aticonfig, I get the following error: no supported adapters detected lspci -v gives me: 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Whistler [Radeon HD 6630M/6650M/6750M/7670M/7690M] (rev ff) (prog-if ff) !!! Unknown header type 7f Kernel driver in use: radeon Kernel modules: radeon, fglrx I also need to mention that when I boot from the install cd, then mount my archlinux system and chroot into it, lspci -v gives me: 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Whistler [Radeon HD 6630M/6650M/6750M/7670M/7690M] (prog-if 00 [VGA controller]) Subsystem: Samsung Electronics Co Ltd Radeon HD 6750M Flags: bus master, fast devsel, latency 0, IRQ 51 Memory at a0000000 (64-bit, prefetchable) [size=256M] Memory at c0700000 (64-bit, non-prefetchable) [size=128K] I/O ports at 3000 [size=256] Expansion ROM at c0720000 [disabled] [size=128K] Capabilities: [50] Power Management version 3 Capabilities: [58] Express Legacy Endpoint, MSI 00 Capabilities: [a0] MSI: Enable+ Count=1/1 Maskable- 64bit+ Capabilities: [100] Vendor Specific Information: ID=0001 Rev=1 Len=010 <?> Capabilities: [150] Advanced Error Reporting Kernel driver in use: radeon So this brings me to my first subquestion: why does lspci work fine when booting from the install/repair CD, but displays "Unknown header type" when booting from my installed system? And my main question is of course: what could I do to get my card working, and X starting? thanks a lot.
