Don't ask me what is missing and what X could do here automatically. We have a workaround to just switch the displays after suspend (not sure whether it's on by default) but it's a config variable. > > https://bugzilla.redhat.com/show_bug.cgi?id=201472 No idea, nothing with backlight, X problem? > > https://bugzilla.redhat.com/show_bug.cgi?id=423931 It's a Dell..., is the dcdbas driver involved?

I have a bug where a lot HP people reported a freeze when using the LID. They should be lucky that only backlight is dark :). Oh wait, _DOS=1 works, _DOS=0 fails -> probably the same issue. This one is nasty and very critical (a lot HPs freeze), but I did not have time to look at anything. > > http://bugzilla.kernel.org/show_bug.cgi?id=9827 Defintely worth a test with IGD enhancements. I just had a quick look on each, do not give much on above statements. If there is any outcome on 9642 (_DOS=1 works, _DOS=0 fails on HPs and LID), pls let me know. Thomas
