    Arrow black sreen when screen is locked

    Hi,

    When I am using suse everything is right. But when I don't use my computer for 6 minutes, the system is locked. (until this everything is ok)

    When I move the mouse or press any key, I can only see a black screen and the mouse pointer.

    The only thing I can do is CTRL-ALT-F1, login as root and run:

    Code:
    shutdown -r now
    Is there any solution for this ?

    Thanks

    I have the same issue since a few weeks. I guess you are also using KDE as your desktop environment, aren't you?
    I didn't found a proper solution so far, but I am using CTRL-ALT-F6 and afterwards CTRL-ALT-F7. Than the login screen is visible again. No need to restart the PC/Laptop. But a proper fix or solution would be nice.

    Hi!

    Had the same with a notebook and some desktops with NVIDIA graphics (all TW with KDE desktop):

    https://forums.opensuse.org/showthre...up-from-screen

    For the desktops the problem resolved after recent updates, for the notebook I had to un-install in YaST:


    Code:
    xf86-video-nouveau
    (take care! after next update it will be back if you don't blacklist it!)
    Kind regards

    I uninstall

    Code:
    xf86-video-nouveau
    from my computer,

    If this doesn't work I'll try CTRL+ALT+F6 and then CTRL+ALT+F7 and see what happens

    I think that maybe is something to do with Nvidia graphic cards, because I have one.

    Let's see what happens

    Regards

    Uninstalling
    Code:
    xf86-video-nouveau
    doesn't work for me.

    I am on an Optimus Laptop and using Nvidia (proprietary drivers) only for gaming. For normal usage I am using the modset driver for Intel. Installing
    Code:
    xf86-video-intel
    doesn't work either.
    It's not a big deal but if it could be solved I would be happy
