It's not a driver bug. We provide the mechanism for you to pass in

Title:
Ubuntu 10.04 LTS is unable to handle analog monitors (resolution
cannot be set)
Status in “xserver-xorg-video-intel” package in Ubuntu:
Invalid
Bug description:
After a couple of years with 8.x on an AMD 64 machine with an Nvidia
285 graphics board, I know switched to 10.04 LTS on an Intel ICH10
machine (quadcore) with onboard Intel Q45 graphics (Fujitsu Esprimo
P5731).
Ubuntu 10.04 LTS is unable to work with my high quality analog monitor
(Samsung Syncmaster 950 p plus). As it is an anlog monitor capable of
going up to 1600 x 1200 at 85 Hz (fh max is 110 kHz) it is connected
to the PC using BNC connectors / coaxial cables - the standard for
high quality analog monitor connection.
BNC connections by design cannot transport DDC information, so EDID is
not available. But instead of either asking the user to manually enter
either the monitor make & model or alternatively it's
resolution/frequency specs, Ubuntu forces the user into extremely ugly
1024 x 768 at 60 Hz. Besides the low resolution, 60 Hz are literally
painful.
After some googling I found some advice in an Ubuntu user forum,
querying a standard VESA modeline at 1600 x 1200 at 85 Hz (cvt 1600
1200 85) and adding this as a new mode (xrandr --newmode [output of
cvt] ; xrandr --admode VGA1 1600x1200_85.00). After that I can select
the correct resolution with System / Preferences.
But annoyingly this has to be repeated after every (!) reboot, because
some nasty automatic function thinks that this resolution is beyond
the capabilities of my monitor (which is not true) and dismisses the
correct setting, reverting to 1024 x 768 60 Hz and giving an error
message after login ("correct settings cannot be determined" - ?).
This is highly annoying! If there is an automatic function, there
_always_ (always, always, always!) has to be a manual override. Do not
try to be overly user-friendly. There is nothing wrong with an
additional, optional, manual settings dialog.
In the meantime until the GUI is fixed, is there a way to persistently
convince the X server (or wherever the dismissal of the configuration
takes place) that the resolution is correct?
