problem when installing Ubuntu I was asked for the resolutions to be made available. Probably because the resolutions at my old CRT monitor can not be read via DDC could. Therefore I have given all the resolutions that the monitor is controlled according to the manual. As a result of my login screen and the desktop was presented in 1280x1024. For a 17-inch CRT monitor, this is not the best choice, especially if the computer by people with inferior eyes can be used.
I also wanted to remove the higher resolutions do not complete the configuration, because the switch that with the shortcuts Ctrl Alt - Alt + Ctrl or would have been impossible.
solution
The resolution of the Gnome desktop could be on the Gnome menu or set user-specific. For the resolution of the Sign-On but I could not find a Konfiguartion tool. The only remedy, the resort of resolutions in the X11 configuration file sudo nano / etc/X11/xorg.conf .

With these changes represented the login screen in 800x600 because this is the first-mentioned resolution. The virtual screen has the full resolution of all things (in my case 1280x1024). If necessary. must also take on the DDC module, as in the article are 60 Hz refresh rate abgegschaltet described too little.
