Comment # 14 on bug 1112638 from Andrea Celli

In comment-5 you wrote:
" I suggest to uninstall xf86-video-nouveau package (nouveau X driver) and
restart X (or reboot). If this doesn't help, also uninstall package
Mesa-dri-nouveau (again restart X or reboot)."

Then i always tried first removing just xf86-video-nouveaMesa-dri-nouveau and
then removing also.

I never user init or startx. I always reboot the system

Now i removed /tmp/.X0-lock AND /tmp/.X11-unix AND /tmp/.ICE-unix.
But, when i restarted system Xserver hangs up again and three files has been
created again.

I too suppose that where is something wrong in any config file. But system
worked fine for a lot of time, years if you consider that i just updated from
an Leap version to the following.
In last months i didn't changed nothing in configurations, except upgrades.
Problem arrived just after last kernel update. Then i suppose that this
operation changed something in some config file.
