I am trying to run Ubuntu 18.04 on a laptop with an AMD A12 processor and Radeon R7 graphics. I am having nothing but problems and am very discouraged with Ubuntu though I used 12.04 for years without such problems.

I have two problems which are terrible and i'll post them separately The problems occur only on gnome and ubuntu on xorg and not on wayland However, i am told that it's best not to run gnome on wayland.

This problem is that the computer sometimes doesn't wake up from a shutdown Well, i think it does wake up because the optical drive spins and the hard drive ticks away, but i cannot login because the lock screen is a hash of colors or a distorted background without a place to login. I cannot even ctrl- alt-f1 to get to a prompt. Everything is frozen

I'm wondering if xorg is configured correctly I am running the oilaf video driver which works well under wayland so i don't know if there is a problem with xorg and that driver.

There seems to be an issue with the nouveau driver Edit the grub file by editing it with sudo access.

sudo vim /etc/default/grub

Add nouveau.modeset=0 to the line that says GRUB_CMDLINE_LINUX="" so that it finally looks like this GRUB_CMDLINE_LINUX="nouveau.modeset=0"

Then run

sudo update-grub

Reboot after successfully updating grub .
