Thread: Black Lock Screen with 2 sessions

    Question Black Lock Screen with 2 sessions

    Hi,
    I Just switched to OpenSuse from Kubuntu and I'm having a couple of problems of instability with the system. I would appreciate it if you could help me with the more important one:

    I have 2 user accounts on the computer. I start a new session and log in with the 2nd user just fine. When I return to the first session, the Unlock Screen is black and only the mouse pointer is visible. It can be moved but there's nothing to interact with. The inaccessible session still runs fine as far as I can tell from "top", and the other tty shells also run fine. I have to restart the computer to log back in.

    I'm using:
    Leap 42.1 64-bit
    Plasma 5.5.5
    QT 5.5.1
    Kernel 4.1.31.30-default
    GeForce GTX 650 running 3 monitors
    OpenGL 4.2.0
    NVIDIA 304.131
    Breeze theme

    Any Ideas?

    Thanks
    A.B.

    You must have some extra repos enabled, I just did a LEAP update and your packages, subsystems and kernel are more recent than mine.

    Pls post your repo list, the following displays (without the full URI for brevity)
    Code:
    zypper lr

    Yes I do, I added a few repos to get the software I usually use installed. First time Opensuse user here, I hope I did't mess things up. Here's the output of zypper you requested:

    Also, have you a good reason to use the rather outdated NVIDIA 304.131 driver? It does support your card, but the default choice should be something like the 367.44 nowadays...
    Maybe you have too many "NVIDIA" repositories enabled? (see #4, #12 and #18 in your repo list)
    Main: Leap 15 Gnome on i7 4720HQ + Geforce GTX960M
    Test: Leap 42.3 (& others) on Core2Duo + GM965

    Post your repo list again, but this time, please do include the URL's, they will tell a much clearer story.

    You brought my attention to the duplicate repos. I followed a few different guides to set things up and it seems that I made a small mess.

    Any how, I removed all duplicate repos and actually removes the KDE Extra repos and downgraded (I think) to the base leap. The problem with user session switching still persists.

    Included is CURRENT the repo list with URL as erquested by @Fraser_Bell

    You may need to "upgrade" rather than "update" to change to new collections of packages
    Code:
    zypper dup
    instead of the usual
    Code:
    zypper up

    I did that, that's how I downgraded after removing the duplicate and extra repos you pointed out to me.

    I just checked and the software version numbers in my original question are still the same.

    Do I need to reinstall at this point?

    Thanks.

    Not yet...
    Please check that the NVIDIA repo you are actually pointing to is:
    http://http.download.nvidia.com/opensuse/leap/42.1/

    From your repo list you appear to point to http://download.nvidia.com/opensuse which might serve packages for a different version of openSUSE.
    You should have installed package nvidia-gfxG02-kmp-default-304.131_k4.1.12_1-41.1.x86_64.rpm
    If not so, you have a wrong version of NVIDIA driver.

    Anyway I would suggest to uninstall all nvidia packages with -304.131 version and install:
    x11-video-nvidiaG04-367.44-26.1.x86_64.rpm
    nvidia-glG04-367.44-26.1.x86_64.rpm
    nvidia-gfxG04-kmp-default-367.44_k4.1.12_1-26.1.x86_64.rpm
    nvidia-computeG04-367.44-26.1.x86_64.rpm

    unless you have a good reason to keep the 304.131 version of course...
    Main: Leap 15 Gnome on i7 4720HQ + Geforce GTX960M
    Test: Leap 42.3 (& others) on Core2Duo + GM965
