[SOLVED] SDDM Greeter with absurdly huge fonts with Plasma 6 / Wayland

gen2arch · 2024-03-16 12:01:27

Hi

after updating to Plasma 6 and using a wayland session I get an ugly sddm greeter with extremly big fonts.

Never happended before.

Ho can I revert that to normal?

Thanks

Please don't paraphrase, https://bbs.archlinux.org/viewtopic.php?id=57855
Most likely a https://wiki.archlinux.org/title/HiDPI issue?

(If you configured the fonts yourself, 8-12 is "normal"; if you configured 20+pt fonts to deal w/ your HiDPI output, that is the problem. If you don't have a HiDPI output you might want to override some of hte autodetects)

Do you run SDDM on wayland, too?

All fonts look great throughout the wayland session; only sddm before logging in is affected.

Is there a way to explicitely set the font size on the sddm greeter?

Thanks

What happens if you simply disable the hidpi setting?
Fonts toobig™, toosmall™ or goldilocks?

I deleted /etc/sddm.conf.d/hidpi.conf: no change, visual elements on greeter too big, like in very low resolution.

I then edited /etc/sddm.conf.d/10-wayland.conf to:

[General]
DisplayServer=wayland
GreeterEnvironment=QT_WAYLAND_SHELL_INTEGRATION=layer-shell,XKB_DEFAULT_LAYOUT=de

that is, I deleted in the "[wayland]" section in it:

[Wayland]
CompositorCommand=kwin_wayland --drm --no-lockscreen --no-global-shortcuts --locale1

Problem disappeared!

But I dug further: upon boot with the offending line in /etc/sddm.conf.d/10-wayland.conf deleted I get in journalctl:

If I understand this correctly:
1. if the "[wayland]" section in /etc/sddm.conf.d/10-wayland.conf is missing: the wayland session for SDDM fails and
2. SDDM runs under X
3. Running under X resolution and size of the visual elements are correct!

So far so good, but here is the really weird thing that really solved the problem:

upon reading this I went to System Settings > Colors & Themes > Login Screen (SDDM):

none was activated! (Breeze, Elarun etc), although I set "Breeze" in "global Theme".

As soon as I set "Breeze" manually also in Login Screen (SDDM) of "Settings", asking for my passwd to do the change, upon reboot I was presented with the "Breeze" Greeter in perfectly correct res and look!

And journalctl -b --grep sddm looks like this:

And: it was the "Breeze" Greeter in fact and not the (old?) one I got before.

Before I didn't get the "purple pill" like, psychedelic tree image but a completely different abstract blue greeter.

So to sum up: after upgrading to Plasma 6 the old blue greeter lingered on, was shown in wrong resolution; manually setting "Breeze" in SDDM Settings solved the problem.

If I understand this correctly:

Yes, it tries weston first, but you don't have that installed.

Mar 17 11:27:26 linux sddm-helper-start-wayland[1210]: Starting Wayland process "kwin_wayland --drm --no-lockscreen --no-global-shortcuts --locale1" "sddm"

returned automatically?
There's somehow no greeter theme in the journal segment in #3 what's consistent w/ your findings.

Did you try to return the HiDPI settings, too?

Yes! I reverted everything back to prior conf: in /etc/sddm.conf.d I now have three files:

1. 10-wayland.conf

[General]
DisplayServer=wayland
GreeterEnvironment=QT_WAYLAND_SHELL_INTEGRATION=layer-shell,XKB_DEFAULT_LAYOUT=en
[Wayland]
CompositorCommand=kwin_wayland --drm --no-lockscreen --no-global-shortcuts --locale1

2. hidpi.conf

[Wayland]
EnableHiDPI=true

[X11]
EnableHiDPI=true

3. an automatically created kde_settings.conf that reflected my manual choice of the Breeze Greeter

[Autologin]
Relogin=false
Session=
User=

[General]
HaltCommand=/usr/bin/systemctl poweroff
RebootCommand=/usr/bin/systemctl reboot

[Theme]
Current=breeze

[Users]
MaximumUid=60513
MinimumUid=1000

Also, an up to now empty file /etc/sddm.conf has been created.

All this being said: I still find everything on the Breeze Greeter to big! :-) although it looks normal now and I guess lots of people like it like that.
Is there a way to configure the look of the Greeter?

Thanks again
