How to Make SDDM Behave More Like KDM?
by enorbet from LinuxQuestions.org on (#5BV37)
My case may be a limited niche but I've been doing it 20+ years so I don';t really want to change my ways if it is at all possible.
I boot to Runlevel 3. There, I login as root, do whatever deeper level work I desire. and then call on a DisplayManager/LoginChooser to get into X. With KDM there was a menuitem for "Console Login" that returned me to the exact original root login and a simple "killall kdm" dumped me fully out of X which is essential for most deep level work even like installing updates or an nvidia driver.
Now, with SDDM, at least launched as root, nothing, not even init 3 as some recommended, will kill all of X. I have to reboot. Additionally, and this may be related, logging in initially as root apparently defeats the ability to use default sddm.conf setting "MinimumVt=7" so I have to Alt-F7 or, better for my normal usage, edit to "MinimumVt=1".
All I want to do is to be able to login runlevel 3 as root and easily return there if and when needed. Can sddm be configured to accommodate my ways. Incidentally, I'm pretty sure the auto-switch to F7 is not being defeated by the graphics driver since it works with other systems, even LiveSlak, although LiveSlak boots to runlevel 4. If that's all there is to my obstacle I could probably give up logging in at CLI if that meant I could get there easily and without rebooting.
