GNOME Bugzilla – Bug 308560
gdm does not honour rotate from Xorg.conf

This bug has been opened here: https://bugzilla.ubuntu.com/12049 "When using the (lcd) screen in portrait mode ( instead of landscape ) thus more pix vertical then horizontal, hardcoded in /etc/X11/xorg.conf: Section "Device" Identifier "NVIDIA Corporation NV34 [GeForce FX 5200]" Driver "nvidia" BusID "PCI:1:0:0" Option "RandRRotation" Option "RenderAccel" EndSection GDM ignores this, this makes that login typing is from top to bottom instead of left to right. Once logged in X session is rotated correctly. Only trouble after that is xscreensaver bug nr 11697: xscreensaver got started with wrong (landscape) parameters."
I would accept a patch to fix this.
The Option "RandRRotation" just means that you have the ability to rotate. You are probably doing something when you start up your session to cause the session to be rotated. Perhaps in your init scripts (.profile or something). If you want the Xserver to come up rotated by default then you need to set up your Xorg configuration differently. The option is driver specific, so you'll have to look it up for your driver. This is not a GDM bug.
