I have a small issue when starting up my machine into Ubuntu. Everything goes smoothly, the login screen appears at the correct resolution. Then it switches to an incorrect resolution, after I login the resolution resolves it self correctly again.

I've followed various threads dealing with nvidia driver issues (I originally started with black screen after getting a new graphics card). With this latest issue I've been through the Xorg.0.log and identified two points that reflect the changes in resolution.

The first part seems to configure the correct resolution

I'm not sure where the configuration is that triggers the nvidia-auto-select, or even if this can be adjusted. Can anyone point me in the right direction?

Have you got a xorg.conf at all? Maybe there are some incorrect settings in there that might cause it to try and set a resolution it doesn't actually support.

I just ran into this issue too. Some desktop environment configs will override xorg.conf settings and show up as "nvidia-auto-select" in the log. In my case KDE had the resolution set in ~/.local/share/kscreen/*

You can confirm that its stored in a local config by creating and logging in with a new user. After that just set the screen resolution to some obscure width/height and grep for those numbers under ~/ to find where the config is hiding
