Hello,
I installed 6.0 on my Dell XPS 9550. When I login, I can do a few things, then my screen goes black, and eventually I see the login screen. Then my screen goes black again. I can’t do CTRL+ALT+F2/F3,etc. I rebooted and set nouveau on the grub boot screen, but it does the same thing. I have a nvidia gtx960m 2gb ddr5. I also notice when I am logged in, after chromium is running for a while, it crashes.
This reply I left in another post might help…
If you had filled out the template asking you to record some information we would know what desktop you are using which probably is a major factor for this type of problem. Assuming Plasma6 desktop this is most likely a problem with sddm or some authentication software or even more likely the interaction between both of those. Another possibility is whether one is using X11 or Wayland. Simple troubleshooting would be if your are using one of those try the other one and see what happens.
What might help people track down the cause of this problem is to get the journal log. For example if this happened on the current boot:
journalclt -b
That is the log of the current boot (or 0). For the previous boot:
journalctl -b -1
You can go further back in time with -2, -3, and so forth, you can list previous boots with journalctl --list-boots. And ofc there is journalctl --help where you can find ways to narrow the information listed among other things.
This problem should have had a bug report and I don’t see one. Did I miss it?
I do recall that a number of users have successfully used the workaround posted by @schappellshow.
I am running kde plasma.
It hasn’t happened in a bit, but will post again if it does.
I ran that enable-linger from the other post.
It’s happening again. It keeps logging me out. So I did CTL ALT F7, but my screen is black, and there’s a cursor blinking.
I get this error when I was logged in on the desktop, if it helps: app-nvidiax2dsettingsx2dload@autostart.service.
That obviously has something to do with nvidia. But the 960 is a much older card. So (realistically) the nouveau drivers should be the ones you use.
Did you try removing any nvidia drivers you have installed, leaving only the nouveau?
Also, I’ve got 3 chromium browsers installed (brave, vivaldi, ungoogled) and all of them have a “crashing problem”. Near as I can tell, that is a Plasma/QT issue. No idea if that affects Rome or Cooker yet since I haven’t tested for that
