How come? I mean, I never really tried to read a lot about it but I always though you would not need to unninstall your driver since all the new drivers comes with mode setting by default.

That is, for example, from Arch Linux wiki:
Late KMS start
Intel, Nouveau, ATI and AMDGPU drivers already enable KMS automatically for all chipsets, so you need not install it manually.

(In reply to tromzy from comment #55)
Removing the xf86-video-intel driver and using Kernel Modesetting instead
seems to have fixed the problem for me...

Ok, thanks you for your reply. Can you explain, what to do to use Kernel
Modesetting instead ?
Is it load by default, if I have remove xf86-video-intel ?
