** Description changed:
Ubuntu Karmic Koala 9.10 (64 bits), fully upgraded.
With double (multi ?) screen, there is screen resolution problems.
Configuration -> I configured Ubuntu to disable the screen on my laptop
(1280x800), to use an external sreen (1280x1024).
Grub2 : Laptop screen isn't disabled, external screen isn't enabled.
Usplash : Laptop screen isn't disabled, Resolution seems ok for both
screens.
Xsplash+GDM :
- Rresolution is 1024x768 on both screens.
- On laptop screen that should disabled, image is stetched to fit with the
screen resolution (1280x800).
- On external screen (1280x1024), image is stetched to 1280x800
resolution, and there is black strips on top and bottom.
- - After GDM, during Gnome loading, laptop screen is finally disabled, but
the image on external screen still 1020x768, on top-left corner and there still
black strips on right and bottom.
- - When Gnome is laucnhed, it's all ok.
+
+ Gnome loading : during first part of Gnome loading, resolution problem
+ remains, but after a few seconds laptop screen is disabled and external
+ screen is finally in 1280x1024 resolution.
+
+ Gnome : it's all ok.
