Title:
[i945] [Xubuntu] wrong screen resolution after upgrade to Jaunty
Status in “xserver-xorg-video-intel” package in Ubuntu:
Fix Released
Bug description:
Binary package hint: xorg
After upgrade to Jaunty, Xubuntu starts with a wrong resolution on a
laptop with external monitor.
hardware: HP Compaq nc2400, with i945 graphics card + Dell 1680x1050
screen, connected via docking station (so the laptop lid is closed all
the time)
software: Xubuntu 9.04, i386; vanilla (untouched) xorg.conf
behaviour with intrepid: gdm uses 1024x768, but after login the screen
switches to 1680x1050
behaviour with jaunty: screen stays in 1024x768 even after login
other observations:
- Settings->Display shows only one screen (Screen 1), but Settings->Desktop
sometimes shows settings for both VGA and LVDS screens.
- I can choose the 1680x1050 resolution in Settings->Display and it works
without problems.
- In Settings->Desktop, I have selected a different background pictures for
VGA and LVDS. Then I see that after login the desktop starts with a background
of the LVDS screen, not the VGA background. This is even more obvious if I add
"xrandr --output VGA --auto" to gdm/Default - then I get the correct resolution
(1680x1050), but I get the LVDS desktop drawn over the VGA one, i.e. there is
the correct VGA 1680x1050 background picture, but over it there is drawn the
smaller LVDS background picture (placed in the top-left corner of the screen).
Looks xorg or xrand draws both screen on top of each other? .. could be a
xrandr bug?
- I could not report this as a xrand bug using 'ubuntu-bug -p xrandr', as
this results in a message that the package does not exist - which is wrong, as
I can ran 'xrandr' command.
- Using the internal screen only (taking the laptop out of the docking
station) works fine, using the correct resolution (1280x800).
- Probably not important, but under intrepid I had problem with the intel
driver, with the system crash with a message about underrun on pipeB .. about
once a day, with no reason I could see. I haven't yet seen it on Jaunty, but I
have had it only a couple of hours..
- I installed grandr and in the Layout screen, both VGA and LVDS are in the
middle box and neither can be moved anywhere. Also the "clone / extend" choice
is grayed out - but that is probably correct, as the laptop lid is closed?
