I downgraded mesa packages and the linux package but now I got only a scrambled image when starting up X.
Using "nomodeset" as boot parameter fixes the scrambled image and also the black screen while booting.
Edit: Sorry, I forgot to mention that I have the x86_64 version of the kernel.
Update: Just upgraded to linux-4.2.5-1, same same... Problem persists.
To solve the problem I had to reinstall (downgraded) : linux packages 4.2.3-1 , xorg-server-1.17.2-4 and xorg-server-common-1.17.2-4
update
i have upgraded xorg (latest package) and, with old kernel (4.2.3-1) ,the system is ok.
The problem is only in the kernel
Seems to be some radeon KMS regression.
Laptop specs: IBM T60p, i686, ATI RV530/M56 GL [Mobility FireGL V5200]
Does a kernel bug exist for this?
sudo vbetool dpms on
Hope this helps.
