Screen becomes black after closing and opening laptop lid.
xorg configuration do not matter and driver version too.
Started around 2.6.* and still reproduced in 18.104.22.1682.
It is Dell latitude laptop.
Kernel configuration and xorg.log here:
Kernel version: all (2.6.30 2.6.29 and others)
xorg.conf tried to change dri of/on, EXA, UXA ... - nothing matters.
p.s. with vesa driver everything works fine.
looks like a dup.
