Sparky Linux Blurry Log In Lightdm Issue [Solved]

[Alexzee]

This log in issue is related to my triple booted Asus Tuf Gaming rig.
Sparky Linux, Debian 12 and Slackware 15 are all installed to their own HDD's.

Upon booting into each distro the Log In screen's are all blurry and the lines make it difficult to see.
Once I log in to each distro the DE's and functionality are good.

I was thinking since the resolution issue 'has been solved' with the monitor and the 165 hertz set it could be an issue with lightdm?
After looking in the /etc/lightdm/lightdm.config file there are so many strings I'm not sure which one to adjust?

LightDM - Debian Wiki

wiki.debian.org

Looking at a portion of the lightdm gtk-greater config gave me ideas in the hope of changing the log in window size or not?
Any thoughts and ideas gentlemen?

I was messing around with the /etc/lightdm/lightdm.conf file last month to change the resolution for the login screen. So the only line I'm familiar with is under the seat section of the lightdm.conf file:

display-setup-script=xrandr -s 1368x768

The above line is after I changed it I believe by uncommenting (or removing the hashtag) and adding everything after the "=".

I also installed lightdm gtk greeter and I'm able to change the settings for the login screen from a GUI.

sudo apt-get install lightdm-gtk-greeter

If you go to accessories in the start menu the GUI program should be there.

Alex, if you go into /etc/lightdm/lightdm.conf and give us (in code tags) the part under

[Seat:*]

I can take a look and compare with my Sparky.

After editing the /etc/lightdm/lightdm.conf in nano uncommenting the string and adding this:

display-setup-script=xrandr -s 1368x768

the the desktop now boots to a black screen complaining about the lightdm manager.

Wow. Are you able to get back into your system?

It works fine on all my machines when using that line. I had gotten that information from an XFCE forum moderator:

[SOLVED] Setting Display Resolution For Login Screen / Desktop / Xfce Forums

Also there was some additional information needed regarding the GUI stuff I mentioned earlier. See the link below.

[SOLVED] Lightdm Login Window Color Change / Desktop / Xfce Forums

I hope you are able to get back into your system.

Now I could fix this by holding down CTRL + Alt + Del and once Sparky starts to boot from Grub just drop into a tty and edit the lightdm.conf file. Undoing the edit I did previously.
I'm somewhat disenchanted with Sparky as there are things I like and some things I don't like.
As I'm sure you can understand we all have are preferences when it comes to our Linux boxes.

I've decided to give Linux mint 22.1 Mate edition a spin.
The download went well and the integrity and authenticity checked out.

Thanks for the education @blizzardfromoz

I posted a reply earlier but I'm waiting for a moderator to approve it because it has links in it. Anyway I'm glad that it was not a system breaking error. Also its probably a good idea going forward to make a back up your system when messing with the login settings. I think I came close to something similar where I could have been shut out of my system.

Thanks-
I just finished the backup a few minutes ago.

Alex, for my own part, I would do as follows:

If you have a Grub Menu, boot to it, have Sparky entry highlighted, and press 'c' for command (likely listed at bottom).

There, type in

videoinfo

and either note down or take a phone pic of the resulting output.

Mine follows

The entry preceded with the asterisk is the one it is currently running on (mine for this laptop).

This list of resolutions is likely smaller than those you will find in eg Settings - Display, but each of them should work.

I would go with that, for starters.
