Screen Resolution not correctly detected

lshw-output

After a manual xrandr --output LVDS1 --mode 1440x900 and reboot the resolution was kept after login screen.
Will check again for the next reboots.

Having a similar problem though I've been slow to report it. Oddly my resolution is not being correctly detected in the OTHER direction as the original poster. My Thinkpad T42 has a 1024x768 display and after updating at roughly the same time, my log in screen and Gnome desktop after logging in were both set to 1360x786... BEYOND the maximum of my Thinkpad's internal display (no external display connected or HAS been connected)

I was able to set the desktop back to 1024x768, but the log in screen is still missing the entire right 337 pixels which hides the shutdown and restart, etc... options off the physical edge of the display.

A screen shot of my gnome desktop is attached, I do not know how to get a screen grab of the log in screen.

Here is my xrandr output. X incorrectly detects my LVDS display maximum as 1360x768.

$ xrandr
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 4096 x 4096
VGA-0 disconnected (normal left inverted right x axis y axis)
DVI-0 disconnected (normal left inverted right x axis y axis)
LVDS connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
   1024x768 60.0*+ 60.0
   1360x768 59.8
   800x600 60.3 59.9
   848x480 59.7
   720x480 59.7
   640x480 59.9 59.4
S-video disconnected (normal left inverted right x axis y axis)

Sorry about the status changes, my mistake, it was meant for another bug, but I goofed...

I'm having the same problem than MrMacman2u. It's really disturbing at the beginning, I'd been wondering a long while where my indicators had disappeared before I found out the problem.
Now, it's fixed in my session but not in gdm, the login box is not centered and some buttons are too much on the right to be reached.

This can be related to bug 640807, but the twist here is that the resolution was correct the first time, on the 9-23 which was after the g-s-d change in question there.

Can you please try to boot from the 10.10 RC Desktop CD and see if the correct resolution is chosen? Then attach dmesg and xrandr --verbose output and Xorg.0.log.

Friday I have been on a presentation - there was another guy with a Win 7 machine and we both had to use a beamer.

What should I say:
1. Attempt: Gnome crashed completely - had to restart gdm
2. Attempt: Needed to call xrandr manually. During normal work it is called too often and when needed....
And after running xrandr, resolution was not correctly recognized. Screen was vertically stretched - had to accept because no time to frickle around.

The Win 7 machine had no problems.
That was embarrassing and is not putting good lights onto Ubuntu. :-(

BTW: This was 10.04.1 and not Maverick in the case described above. Anyway I do not consider Maverick working much better as Lucid is at least correctly determining my main screen resolution...

I had the same problem when upgrading to 10.10 and I have ubuntu 64 bits here, not i386

hope I can find a way to solve it, don't want to get back to ubuntu 10.04

Washington, unless you have the same hardware, please file your own bug report. Please subscribe me to it.

Problem seems to be solved with release (I am the original reporter of the bug).

Good to hear. It seems indeed it was a duplicate of bug 640807 then, marking as such.
