I have an Optimus laptop (Dell Xps) which I used for over 2 years now, and never installed the Nvidia driver before. Recently I installed the Nvidia proprietary driver and after the last kernel update I tried prime-select for the first time. The system was using the intel driver, so I typed „sudo prime-select nvidia“ and then logged out and in again. The first thing noticed was a red tint, so something was different indeed. I was able to confirm that the Nvidia driver was loaded.
So my next step was to load the intel driver again, I typed „sudo prime-select intel“ and tried to re log again. But this time, after logging out, the login manager did not came back again, I just got a black screen. I restarted my system again, but since then allways right at the moment when the login manager should show, I get a black screen.
Closing and opening the lid again does not help, the screen stay black with a static horizontal cursor/inticator showing in the upper left corner.
I also cannot switch to a console, loading an older kernel or starting in recovery mode has the same result.
i can boot from a read-only snapshot created right AFTER zypp though.
I is there a way to at least completely switch back to the read only snapshot?
I mean, to roll back to the snapshot, but not being restricted to read only?
Thank, i can boot my system again now and it works normally. But i will do not touch prime-select for a while and just use the system in the intel mode. Maybe when the new nvidia driver and a new kernel is out i will try it again…
Btw: it is pretty great that the system creates a new snapshot before and after every zypper dup
