Kubuntu 20.04 Login Screen scaling

pk flag

I have recently had to reinstall Kubuntu 20.04. I am using HDMI to a HDTV and I have set the scaling to 112.5%. This works great, but the login screen is super small. I have checked around online, and I see several references to adding in settings to the sddm.conf, but I am not finding that in Kubuntu 20.04 in /etc/. I had corrected this in the past, but sadly I did not bookmark my reference, and my google skills seem off from that time.

Additionally, I have 'lines' that show up when I open a terminal, and seem to shift when I move the cursor. These line are a thin horizontal view of the screen below. I believe that this is also related to settings in sddm.

I have tried a few nvidia drivers, but no change.

If you can point an ol fool in the correct direction, it would be much appreciated.

Best regards and stay safe

Wanted to follow up with a solution that worked for me, with hopes it will help others.

For the login screen scaling, the sddm.conf was not found, but a post I had read pointed me to -> sudo nano /etc/sddm.conf.d/kde_settings.conf

At the bottom of the config file, I placed in:

[X11]
ServerArguments=-nolisten tcp -dpi 96

  <-- your number may need to be different.   

For reference, this is the full config of that file - yours may be different, and I only added the [X11] and the line below that.

[Autologin]
Relogin=false
Session=
User=

[General]
HaltCommand=
RebootCommand=

[Theme]
Current=Nordic

[Users]
MaximumUid=60000
MinimumUid=1000

[X11]
ServerArguments=-nolisten tcp -dpi 96

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
