Intel driver breaks 1680x1050 on TMDS-1 output

[Anthony Liguori]

Binary package hint: xserver-xorg-video-intel

When using 1680x1050 and outputting to an external monitor via DVI, the driver outputs in 1680x1053 causing portions of the screen to be scaled and fuzzy. This problem has been discussed and fixed in the upstream tree. More information is available at http://lists.freedesktop.org/archives/xorg/2007-July/026528.html

I have confirmed that this bug is present in the latest gutsy package (2:2.1.0-1ubuntu1). I have also confirmed that this is fixed upstream (I'm using 15f71edba37738f8ba279fa07452fda10cc65298).

I'm using a T61 laptop and have an Samsung 206bw monitor.

Logfiles have been generated with "Xorg -verbose 9 -logverbose 9". There are no real differences between the "good" and the "bad" one.

Several problem have been reported in driver 2.1.0 due to this commit, and they have been fixed since then. So your bug is very probably fixed in current git HEAD.

Did you try master? Should be fixed already.

Gutsy has 2.1.1, so this bug should be fixed. If not, please reopen.
