Using intel video drivers with kms and i915 on arch linux I haven't been able to start Xorg in a different tty than from the calling one logged as root. By example:
Logged as root on tty1
X vt7 :0
Freezes the PC and within the Xorg.0.log I see
intel(0): failed to set mode: Permission denied [13]
In the other hand
Logged as root on tty1
X vt1 :0
Everything works as usual
I know is not really a serious problem since I still can use Xorg but I'm really intrigued about this behavior for two main reasons
- permissions for all tty1 ... tty49 are cwr-w----- root tty
- even if a I'm logged in both tty1 and tty2 with root and try to start X server on tty2 from tty1 it doesn't work as if it only had permission for the calling tty
Does anyone have and idea on what's going on?
