Comment 14 for bug 355629

Thank you for the information. You say your monitor is on the laptop (they are connected through something called LVDS). You never had an external monitor connected when you had the problems? Your first log says there is an external monitor connected to the TV-out port, and this is what is causing the lower resolution (it tries to mach the resolution with what it thinks is on the TV-port). It is not an uncommon problem that the driver thinks there is something on the TV-port when there isn't.

First of all, it seems like this behaviour is not related to the package version of the intel driver, but is something that comes and goes randomly. It would be nice if you could confirm this by logging out and in several times. The resolution should be fine every now and then and wrong every now and then.

Secondly, when you have checked that this comes and goes, take a look at https://wiki.ubuntu.com/X/Quirks under "Ignore TV Output Quirk" (the behaviour is nowadays a lower resolution instead of what is shown in the picture). Try to disable TV-out and verify that the bad case never happens again. (I have a very similar bug, except that it is the VGA that pretends to be there every now and the, bug 273306).

Finally, what is your exact laptop model? Does it have a TV-out connection at all?
