    Default Np graphical login, SDDM eats 40% CPU

    After upgrading to 42.3, and taking the steps to uninstall the propriatory Nvidia driver and install the community one, as advised. But I getoond no graphical login, and sddm takes 35-40% cpu permanently, accessing the disk continuously. Graphics card is GForce 7025. What is going wrong here?

    (I posted initially from phone, and that gave some typo's. Don't know how to edit the post, so I'll rephrase it for better readability

    I upgraded the machine of my father-in-law from 42.2 to 42.3, and took the steps to uninstall the propriatory Nvidia driver and install the community one, as advised on

    I uninstalled and installed the driver after upgrading, before reboot. It is not a laptop or notebook.

    After a few unsuccessful measures (deleting nouveau, deleting nvidia-based drivers and installing nouveau) I decided to install 42.3 from scratch.
    Works now as expected.

    Same problem here. Upgraded to OpenSUSE 42.3 and SDDM eats 20-30% of CPU. Intel x5650 (xeon 6/12), 32GB memory, Graphics is MGA G200. No Nvidia card or drivers. Eliminated Graphics Login and CPU usage went to less than 5%. I'll run w/o graphic login - but this bug should be fixed!

    If you think this is a bug, then posting here will not help. Report the bug against 42.3's sddm at bugzilla.opensuse.org

    Were you upgrading from 42.2? That is a very old video card. Likely to be impacting here.

    Right, in particular it doesn't have (hardware-accelerated) OpenGL support AFAIK, so the software OpenGL renderer will be used.

    Better use a different login manager, e.g. kdm, lightdm or xdm.
    You can set that by changing the DISPLAYMANAGER="xxx" line in /etc/sysconfig/displaymanager (of course you need to install the one you want to use as well)
