I’m trying to fix the Nouveau driver bug. When I wake up my computer from sleep, the screen remain black, no image. So I added the
nouveau.modeset=0 in the grub file and after a reboot, the screen resolution is on 800×600. And there is no other options available in the config menu.
I also tried to install the last nVidia driver from the PPA but the computer become extremly laggy after a reboot. I have a nVidia 980M with Ubuntu 18.04.
How can I fix the nouveau bug while the usual fix creates other bugs?
