So with the lack of newer X server support in fglrx, I decided to take the plunge and try out the open source drivers. However, I ran into a minor problem. When I enable KMS and start X, I get a blank black screen. Any ideas?
Thanks in advance.
I'm running Debian testing, have a Radeon HD4670 (ChipID = 0x9490).
X.org - X Server 1.7.5
Kernel - 2.6.32-trunk-686
Libdrm - 2.4.18
Radeon - 6.12.4
I can confirm KMS does work, if I stop X and goto a terminal, I can rmmod radeon, modprobe radeon modeset=1 and clearly see a KMS terminal. dmesg | grep drm shows [drm] radeon: Initializing kernel modesetting. However, when I then try to restart X, either by /etc/init.d/kdm start or startx, the screen goes blank and the machine becomes unresponsive. Booting with modesetting enables causes a similar problem - after grub I get no video output.
