Comment 2 for bug 775089

Hi Chris

Thanks for your response

I may not have explained the problem clearly.

*first a little background: *
From what I understand, ubuntu automatically detects your monitors
resolution/resolutions and populates a list of choices.
when you go into applications/monitors, you are then able to select one of
those items from the list.
My monitor is an acer with an aspect ration of 4:3. but what is happening in
my case is that ubuntu is listing resolutions for both 4:3 displays as well
as 16:9.
and even though I have a 4:3 display, it is defaulting to a 16:9

so my install menu, grub menu, login screen, boot up screen and actual
system defaults to this 16:9 aspect ration.

unfortunately 16:9 is incompatible with my monitor, and so my monitor
displays a large error message across the middle of the screen that doesn't
go away.
This blocks out a large portion of the display.
the log in screen sits in the middle of the display also, and because it is
being covered with an error message, I am unable to log in.

If I select the correct resolution using applications/monitors, the error
message goes away and I can then use ubuntu.

*But here is the paper cut*- the grub menu, login screen, splash screen and
exit screen remain at the original 16:9 aspect ratio resolution.

when I choose my preferred resolution, it should carry that choice through
to those four screens as well

In the past I had to fix this manually by going into X11/xorg.conf and
editing that file manually. Unfortunately this solution has not worked since
9:10, or there about.

for more information, here are other people discussing this problem :

thanks once again
