Recent OS update caused very tiny login print, icons, for splash screen and desktop

Rocky Linux Tech Help
1

I recently under went a software update and after the installation the login screen came back with very tiny icons and print. My desktop was basically the same. Very small icons and small print. I believe the update was from Rocky Linux 9.4 to 9.5.
Existing config
Rocky Linux 9.5(Blue Onyx)
GNOME Version 40.4.0
Video Card is NVidia RTX 4000 SFF

It is totaly possible that this could be a video driver issue. I have not tried to install an NVidia driver. How can I get help with installing the appropriate video driver? What do I need to do to get a larger login splash with large icons and print? Any help would be greatly apprecaited.

I think you’re talking about the GUI login, as opposed to a console login.

It might be looking at

Gnome Settings : Displays

and see what resolution is says

The same screen also offers scaling.

Greetings,

After further research, I found information on how to install the NVIDIA video driver for my
RTX 4000 SFF ada
I followed the Rocky Linux instructions for installing video drivers and was able to successfully install the driver. Under my Display Settings=>About=>Graphics I see the following
"NVIDIA Corporation AD104GL [RTX 4000 SFF ada Generation]
I feel like I now have the correct video driver so I feel like I’m making progress.

Under my display settings I raised the “Scale” to 200%. I still have questions
My font size and icons on the login splash screen are still tiny and need some help with how to increase the sizes?

I could use some help with steps on how to update the video driver as video files frequently get updated?

@jhi I merged your two threads, please don’t start new ones when it’s relating to the same problem thx.

Thanks for responding.
How do I get into the “Gnome Settings : Displays”?
On my desktop I was able to change the display to 200% which is much easier to read.
Just need to figure out the GUI login scrren?

Thanks

I found this related to Fedora:
Configure gdm login screen

If you search with this term " configure gnome login screen dpi" you will see several hits, mostly ubuntu but the answers are similar to above. There does not seem to be a GUI way of configuring in Gnome.

Thanks to all. jbk23, the link very much describes what I’m seeing too with my Gnome GUI. I’m not sure where the same Fedora files might be located in Rocky Linux. Maybe this could be passed along to developers and looked into for a future Gnome GUI fix.

Appreciate the help.

Lightdm is the window manager that comes with Mate installs which I use and is available through EPEL. The lightdm WM does have an option to manage the login screen in it’s settings menu. It worked for me on a high resolution laptop screen. It may be possible to install on your system and use instead of gdm. I don’t know how to do that though.

The process for installing and enabling lightdm on Rocky 8 is as follows:

dnf install lightdm
systemctl disable gdm
systemctl enable lightdm
systemctl isolate graphical.target

It’s probably the same on Rocky 9 but you might want to verify that first.

10

Followed the process for installing lightdm. I now have a directory titled
/etc/lightdm
This directory contains the following files
keys.conf lightdm_conf.bkup lightdm-gtk-greeter.conf users.conf
lightdm.conf lightdm.conf.d lightdm-gtk-greeter_conf.bkup

As you can see I’ve made backup copies of lightdm.conf and lightdm-gtk-greeter.conf. From a website it described modifying lightdm.conf under “[Greeter]” but on my install “[Greeter]” is in the lightdm-gtk-greeter.conf and looks like this

[greeter]
background=/usr/share/backgrounds/default.png
#user-background=
#theme-name=
#icon-theme-name=
#font-name=
#xft-antialias=
#xft-dpi=
#xft-hintstyle=
#xft-rgba=
#indicators=
#clock-format=
#keyboard=
#reader=
#position=
#screensaver-timeout=

Because I would like a larger GUI login I tried modify the file lightdm-gtk-greeter.conf to uncomment the “#position” which I set like this
position=center
size=large

I saved and did a systemctl restart lightdm and did not get the desired font size nor the GUI login in the center of the screen.

Question : which file is the correct file to modify and what would the correct modification to the code look like? As always any help is greatly appreciated. Thank you

In mine I have have these two lines

[Greeter]
background=/usr/share/backgrounds/cosmos/helix-nebula.jpg
enable-hidpi=auto

You can ignore the background line. Font sizes don’t work. It probably requires the full path to font file of the correct type.

I went with the following

enable-hidpi=auto

Not really seeing any change in the size of the login text box with this. I did a diff on the file with the backup and it shows that change. Any other suggestions. My goal is to get the gui text box larger.

Thanks

Is the lightdm-webkit2-greeter available to use? Which repository might have it? I’ve tried searching using dnf with no results.
