The login screen was fine on first boot with Nouveau but when I installed nvidia-381 from the graphics-drivers ppa and rebooted my login resolution is extremely high making the font and ui really small. I can still login just fine but it's an eyesore and I'd like to get it fixed.

In my searching for an answer I found a solution of setting my resolution through system settings and copying the monitors.xml file from my ~/.config folder to /var/lib/gdm3/.config but obviously that didn't work.

  • Ubuntu Gnome 17.04

  • Nvidia 381.09 w/ nomodeset (It won't display the login screen otherwise.) I've also tried 378.13 and it didn't work either.

  • Screen res 1360x768

  • I upgraded from 16.10 to 17.04 but in my case the login screen has lower resolution and everything is larger than normal. All results I found about this are outdated, would also want to know how to easily fix the resolution of gdm3. – Sir_FZ May 6 '17 at 12:21

I figured this one out! I have an Asus Q534UX with a 4k display. I noticed that my screen resolution was set to 4k, but I had my scaling set to 2 which makes the desktop usable while still in high resolution.

Once choice is to set the scren resolution to something other than 4k, but that isn't ideal especially when it's not your displays native resolution.

The answer is to do as you've said, copy the monitor.xml file to /var/lib/gdm3/.config and then edit it so you can change the resolution to something more reasonable in the login screen. I changed mine to 2560x1440 but that may be still a bit high. It is MUCH better.

You're only in the login screen for a bit, then when the desktop comes up the resolution and scaling goes to normal.

Save your edits and reboot to see the changes.

  • Set it to 1280x720 and 800x600 but it still doesn't work. It doesn't scale the UI just the resolution. Pastebin – Ubuntuthrow May 13 '17 at 8:18
