" Oh no ! Something has gone wrong. " after messing around with gtk-3.0 files

General Help

Hello !

I've been interrested into customisation of zorin since a few months , fully expecting things to break ( i am not the sharpest tool in the shed ) i decided to give it a try today and i did indeed break things .

I found on this forum a bunch of code that was supposed to make the windows slightly transparent , to paste in a gtk.css file under ~/.config/gtk-3.0 as you can find below :

.background {
color: #fff;
background-color: rgba( 10, 10, 10, 0.6);
}
window.csd {
background: rgba( 10, 10, 10, 0.5);
window.dconf-editor {
background: rgba( 10, 10, 10, 0.94);
}
.content-view {
color: #fff;
background-color: rgba( 10, 10, 10, 0.4);
}

Once done , i saved , logged out and logged in again only to be greeted with a " Oh no something has gone wrong " screen with instructions to try logging out and back again , which failed .

Here is what i have tried :

  • navigating to the file via a terminal to delete it .
  • installing updates to see if it would have regenerated the directory as it was before .
  • reinstalling zorin-os-desktop , zorin-os-pro , zorin-os-light , zorin-os-default-settings
  • reconfigurate GDM3 to its default values

Sadly , my live USB key failed on me as it was already a fairly old one , therefore i wasnt abble to attempt a live boot to see if i could fix anything .

Do you guys have any idea ?
Thanks a lot

Welcome to the Forum!

So, the File is deleted, yes? Did You checked that? And have You rebooted after deleting it?

What you changed should not have had that result - and your fixes would have fixed it if it somehow had...

So it is far more likely that something else is the culprit.

What applications have you installed? Have you added any Gnome Extensions?

Thanks , the file was indeed deleted i checked twice , first after deletion , the second after somehow managing to remake a bootable key with the terminal , therefore making a live instance to check .
I have rebooted as well after deletion , still the same result , the only change happened after reconfigurating GDM3 , the " Oh no " screen went from dark theme to light theme

I installed and removed a lot , i would be unable to tell you what is left and what is gone within all those files , it has to be noted however that all those modifications happened months earlier .
When it comes to Gnome extensions , i wanted to give a try to blur my shell last august , i wasnt abble to understand any of it and i ended up removing the extension itself as well as the extension manager

Before this happened: Came there any System-Updates?

No , the updates happened after , packages only .

During my first installation back in april i encountered an issue due to mounted disks UUIDs within Fstab ( everytime i was booting , i was given the recovery mode ) , the only fix that worked was navigating to fstab , deleting it and rebuilding it using -echo "UUID=yada yada yada / ext4 blablabla " 0 1 " > /etc/fstab- .
I've spent so much time writing that command that its the very first linux command i knew off by heart .
My question is , similarly to that fstab issue , is there a way to delete and rebuild anything gtk related within the files ?
