I’m very new to Linux world, please forgive me. I fighted this for two days, no sleep and offer my solution for your judgment. Any comments are welcome.
All problems started 48 hours ago. Like many others I just did update (possible 460) or kernel or ubuntu… something got updated. After restart, black screen. I tried recovery mode, figure out that it is nvidia driver problem. Manage to load system running a comand line in recovery mode: sudo prime-select intel.
Loaded system and try everything, purge all nvidia, install different drives nothing helped. Black screen…
I gave up and installed Ubuntu 20.04 from scratch + 3rd party option selected. MY big surprise it did not work, loaded with black screen!!
One main thing that was constantly slowing me down and annoying is GRUB 2.04. It is slow, click takes seconds, most of time doubles keyboard keys clicks, have no idea when one click comes, hard to run recovery mode.
I install Ubuntu 20.04 again from scratch. This time normal with no updates and no 3rd party. Loaded nicely. Did update via Ubuntu + run this: sudo apt-get install ubuntu-restricted-extras - to get all the extras. Restart. All good.
This is possible solution now: I really hated GRUB. So after reading and testing a lot I added (remove #) this two option:
and removed “quite” to get:
This forced GRUB to stay in TEXT only mode and not load graphics! I propose that this was messing up the Nvidia loading drivers properly.
Next switched DVI cable to HDMI, I do not know why…
Next, went to ubuntu software update and selected 460 (proprietary, tested).
Reboot, what a surprise - loaded with no issues!!!
Please let me know if anyone having problems can change grub settings and check that it helps you too…
To change grub:
sudo gedit /etc/default/grub
(make changes as above suggested)
RUN: sudo update-grub
P.S. Discover timeshift by the way, I guess this is the way to go forward with updates? Any other suggestions how to avoid system changes? Do I stop updates? Kernel update?
