** Description changed: Binary package hint: gdm I have a screen connected via DVI passthrough on my T61 docking station. xorg is able to both detect the monitor and detect the resolution. This bug occurs booting both with the lid open and with the lid closed. - When running GDM to log in or switch users, however, it refuses to - display on the external monitor, and displays ONLY on the laptop screen. - The display is totally wrong, though -- the laptop screen is 1440x900. - The external monitor is 1920x1200. As if to compromise, the desktop - displays at 1600x1200. Since this doesn't fit on the laptop screen, it - is cropped. Incidentally, the screen does not pan when moving the mouse, - so I can't access any options on the bottom part of the GDM screen. + When running GDM to log in or switch users, it refuses to display on the + external monitor, and displays ONLY on the laptop screen.

To test this out, I created a new user. - Of course, GDM was only displayed on the laptop for both a regular login after starting the computer AND after already logging in and attempting to switch to a not-logged-in user. + GDM was only displayed on the laptop screen for these cases: + 1) logging in for the first time + 2) switching from a logged-in user to a non-logged-in user + Switching between logged in users uses the screensaver apparently, which is not affected. - After logging in for the first time under a new user account, it also - displays on the laptop and at the funny resolution. + After logging in for the first time under a new user account, the screen + is also only displayed on the laptop (and at the same odd resolution). For some odd reason, entering the Screen Resolutions preferences and changing the resolution from 1600x1200 to 1920x1200 changes back to the external monitor; what's more, changing BACK to 1600x1200 still displays - on the external display (and correctly so). + on the external display (and rightly so -- 1600x1200 is a supported + resolution of the monitor). So in summary -- GDM does not display on an external monitor, and passes these settings to the first login of a new user. The new user can easily switch to the external monitor, but it remains impossible to log in without opening the laptop lid to see the screen.
