Important: the information in the description field of this bugid is incorrect (!). I thought that enabling the "ForceEnablePipeA" option resolved the issue, but I always performed the tests right after X started. It now seems that after keeping the lid closed for a while or "closing/opening" the lid a couple of times, X will eventually hang anyway.
Bryce, this might have impact on freedesktop-bugs #15885 (!!). Sorry!
Scenarios tested, all resulting in X hanging eventually.
a) "ForceEnablePipeA" = true + autologin is enabled
b) "ForceEnablePipeA" = true + autologin is disabled
c) "ForceEnablePipeA" = false + autologin is enabled
d) "ForceEnablePipeA" = false + autologin is disabled
e) a) + Control-Alt-Backspace
f) b) + Control-Alt-Backspace
g) c) + Control-Alt-Backspace
h) d) + Control-Alt-Backspace
Again, I'm terribly sorry for the confusion I might have caused.
