I upgraded from ubuntu 17.04 to 17.10 (32 bit) and I wanted to set resolution to 1600×900.
after lot of researching I did this (https://ubuntuforums.org/showthread.php?t=2374840)
Ubuntu login screen
( It's saying —-In Ubuntu 17.10, restart your system. At the login screen, under the password field, you’ll see a gear icon. Just click on it and you’ll see two options here.
The default Ubuntu means it will be using Wayland while Ubuntu on Xorg obviously means it will use Xorg. You can select Ubuntu on Xorg to use Xorg here.—-)
And after that I did this How to set a custom resolution?
I rebooted pc and on login screen I clicked on gear and chose ubuntu on xorg
and I am having blank screen now.
I rebooted and selected option Ubuntu, then it starts fine. but ubuntu on xorg is not opening nor the resolution is fixed.
Thanks For Help.
