    NVIDIA driver does not load? on new session

    Hi all,

    When I start a new session (from menu -> switch user), I get a black screen and moving mouse cursor on one of my 2 monitors, secondary monitor gets no signal.

    I suspect the NVIDIA driver does not load. Problem does not occur on X-org driver, but the NVIDIA performs (much) better.

    I tried a fresh install, but the problem persists.

    Any help much appreciated!

    In the logs I find:

    Xorg.1.log:

    To be clear, the NVIDIA driver IS being loaded/works properly on an initial boot/log in with the user account that installed the OS, but once there, doesn't seem to work when you switch to another user? Is that correct?

        As a test, assuming you haven't tried it, logout and reboot and log in using the 'other' user you created. Does the Desktop load as expected, or is the same issue being presented as in your initial post?

          I tried that, the other user loads after boot.

          If I try a second session from that other user, same problem.

          It seems adding a second session causes the problem, regardless of the user (or admin status thereof)..

            Okay. So let's find out what Groups you and the 'other' user belong to. This will take a logout/reboot to obtain the data.

            Reboot and log in as yourself. Once the Desktop loads, open a konsole and type: groups

            Note the results (write them down).

            Now switch users. Yeah, you won't get a Desktop (issue presents). Switch to a TTY then run the command: groups

            Note the results (write them down).

            Reboot, but this time log in as the 'other' user. When the Desktop loads, open a konsole and type: groups

            Note the results (write them down).

            Report back.

              Thanks for your help: Here's my report:

              After boot, I logged in as user: baze (the admin accound that installed Kubuntu)

              Opening konsole:
              Code:
              $ whoami
baze
$ groups
baze adm cdrom sudo dip plugdev lpadmin sambashare
              Then, pressing ctrl alt F2, I opened a new tty, logged in as secondary user: enkidu (the non admin account)

              In tty:
              Code:
              $ groups
enkidu
              I rebooted, logged (succesfully) into Plasma as user: enkidu, opened konsole:
              Code:
              $ groups
enkidu

                So you aren't using Logout (from the Desktop) and then Log in with the 'other' user. I think there is a difference between what you are doing and what I just said. That said though, I tested logging out/logging in (with a test user account) on my 18.04 install, and doing so has the Desktop loading properly (but I don't have NVIDIA), and konsole groups command for the test user shows what you are getting; just the username.

                Does this other user of yours not need Admin privileges? If, while logged in as your normal user and you edit the 'other' user and 'Enable administrative privileges for this user', and try again, does the Desktop load?

                  Thanks again for trying to help me out. Here's what I tried:

                  If I switch users by logging out and in, I have no problems. (same as you tested, didn't think of trying this before..)

                  The session hangs when I do not log out, but add a second session (Power/Session -> Switch user).
                  Then, when I add a new session, screens turn of and on, thereafter only one screen shows the (movable) mouse cursor on a black background, so even before I can try to log into that session as a user.

                  It is no blocking issue, as I can log out from (and suspend/quit) the first session, as you mentioned, and start a new one as the other user. If there would be a straight-forward fix so I can run 2 sessions simultaneously (as works using the X-org driver instead of NVIDIA), it would be even better, but don't waste your time on it ..

                    That said, and with the information we've gained, I think that a solution will be offered by those who use NVIDIA. So, as they say, 'stay tuned'.

                      what version of the driver are you using , and is it the one from the Ubuntu repo , the graphics drivers PPA or Nvidias website ?
