Leap 16 Small Font Login Screen

English Install/Boot/Login
1

Hi folks,

I successfully installed Leap 16 on my Dell Laptop and I love it.
The only problem i couldn’t figure out is the login screen setting. Everything is too very small.
I played unsuccessfully with all the option under Login Screen (SDDM) … like Apply Plasma Settings etc …
My current global scale display settings is at 212.5% global settings.
Fonts “force font DPI” = 200

Any idea how to get a normal font sized login screen?

The same here with this HiDPI monitor – 140 dpi –

I’ve tried various solutions and, have given up – but, I haven’t tried any of the alternative offered by the KDE Plasma “System Settings”.

  • I’m living with the tiny bottom left font size on the “Breeze for openSUSE” SDDM login screen for the moment.
    Maybe I’ll raise a Bug Report at sometime in the future …
 > cat /etc/sddm.conf.d/10-HiDPI.conf
[X11]
EnableHiDPI=true

[Wayland]
EnableHiDPI=true
 > 
 > grep -i 'HiDPI' /usr/lib/sddm/sddm.conf.d/*

MinimumVT=7

BTW, the Leap 16 ‘sddm.conf’ man page, doesn’t mention the section name [XDisplay] …

  • Oh dear – I can feel “Yet Another Bug Report” in these old bones … :smiling_imp:

Try adding

export QT_SCALE_FACTOR=1.5
export QT_FONT_DPI=140
export QT_AUTO_SCREEN_SCALE_FACTOR=0

to /usr/etc/X11/xdm/Xsetup

@deano_ferrari:

That will increase the font size of everything – not only the small print on the SDDM login screen …

I suspect that, the better way is to change the “Breeze for openSUSE” SDDM login screen …

I tried the “Breeze”, “Elarun”, “Maldives” and “maya” SDDM login screens –

  • Only “maya” had an acceptably sized Session type selector …
  • Apart from “Breeze”, they all have only US keyboard input and, virtual on-screen keyboards – no fun trying them out …

AFAICS, one way forward will be to raise a KDE Bug Report requesting that, the “Breeze” [which is a KDE theme anyway] SDDM login screen be changed with respect to the bottom left session selector text.

Another way forward:

  • I hit the “Apply Plasma Settings…” on the KDE Plasma System Settings “Colors & Themes” → “Login Screen (SDDM)” page.
    This dropped a file named ‘kde_settings.conf’ into “/etc/sddm.conf.d/” with the following content:
[Autologin]
Relogin=false
Session=default.desktop
User=

[General]
HaltCommand=
Numlock=on
RebootCommand=

[Theme]
Current=breeze-openSUSE
CursorTheme=Oxygen_White
Font=DejaVu Sans,12,-1,5,400,0,0,0,0,0,0,0,0,0,0,1

[Users]
MaximumUid=60000
MinimumUid=1000

The bottom left session selector text of the SDDM Login Screen is now a little bit larger and definitely more readable than what was previously there.

Yes, you can do that, but best to copy and modify the theme you are using, eg breeze6 → breeze6-hdpi
