[Bug 355629] Re: [iGM45] boots to low resolution sometimes

[Geir Ove Myhr]

Thank you for this information. Now that we have confirmed that this happens randomly independent of the package version, we'd like to confirm that disabling the TV-out really takes care of this (I would be very surprised if it doesn't). This test may be a bit tedious, but should remove any doubt about my suspicions.
1. Log out and in again several times. Each time you log out the X-server is restarted and the "bad" case may happen (i.e. you get lower resolution than expected). Count how many times you have to log in and out before the bad case has happened three times. (If you install fvwm and switch default desktop session to that temporarily, the login/logout will be much faster than with KDE/Gnome).
2. Add the TV-out quirk to your xorg.conf as described at https://wiki.ubuntu.com/X/Quirks .
3. Log in and out the same number of times. Verify that the bad case never happens.

There is one more test you can do if you want to that may tell us how similar this is to bug 273306. When you have the resolution you want, run xrandr several times. Does it show "TV connected" instead of TV disconnected every now and then? If you find this hard to spot manually, you can write this on the command line:
for a in `seq -w 1 200`; do echo $a; xrandr >xrandr-$a.out; done
This will generate 200 files with xrandr output with filenames xrandr-XXX.out. To see if any of them are different, run
md5sum xrandr-*.out | sort | less
This will list the md5sum of all the files, which will be the same for most of them, but you can then check out the different ones.

As a side note, I noticed from the log that you have set a few options
in you xorg.conf. For documentation, could you attach that file to this
bug as well? Also, both your xrandr --verbose outputs are for the bad
case, it would be nice to have one for the good case as well (it will
probably have TV disconnected but without the 0mm x 0mm part seen in the
uploaded files).
