[Bug 355629] Re: [iGM45] Regression on version 2.6.3-0ubuntu5

[Geir Ove Myhr]

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?
