Problem has occurred-message forcing to logout the session

so, I had already previously problems (Dynamic taskbar returning back to static after some time) which I though that ... come on, it doesn't matter. Maybe it is because I'm using some gnome extensions.

but now Im really, really frustrated!
To check, if really the extensions are the problem, I deactivated all custom extensions so that it looks like this:

All custom extensions have been deactivated until now:

And guess what? Again, after a few days may pc "crashed". So the PC was locked, I waked up and typed in my password and this, I hate this message meanwhile so much, appeared:

So, again my whole session was lost. And, idk if this helps, everytime it changes to this gnome basic theme/desktop layout, because after logging in back the desktop is always empty and only if I use the super button it shows the desktop layout:

Changed Desktop Layout:

The only thing I'm changing is back to windows-looking desktop-layout and this option which Im deactivating- thats. it!

Button which Im deactivating:

anyone else who has this problems? it's so annoying. of course, the packages are always up to date.

Hmm ... are secure Boot and Fast Boot in BIOS disabled? If not, disable them.

Then try the following Command:

sudo apt reinstall zorin-os-desktop zorin-appearance zorin-appearance-layouts-support zorin-appearance-layouts-shell-core

Another Thing: does Your System run in Wayland or X11? You can check that with the Command echo $XDG_SESSION_TYPE

What Graphics Card do You use? If Nvidia: What Driver Version?

Fast boot not sure, but secure boot is activated- I thought, if it is possible to install it with secure boot, then it shouldn't be a problem?

echo $XDG_SESSION_TYPE
x11

I'm confused, because I thought Zorin uses wayland :confused:

GPU:
AMD ATI Radeon 540/540X/550/550X / RX 540
AMD ATI 11:00.0 Raphael

I'll try the command maybe after the holidays, don't want to brick something during the holidays :grin:

By default, it should use Wayland, yes. Did You switched maybe? But You can switch anyway to Wayland if You want to try this. Go to the Login Screen and click there on Your Profile so that the Password Field appears. When it is appeared, You should see in the bottom right Corner a Gear Icon. Click on it and choose the Option ''Zorin Desktop'' and then log in.

Can be but don't have to. You could try it with disabled Secure Boot. You can enable it again if You wish.

I don't know that I consciously changed it.

Unforunately there literally only the password field :frowning:

Thanks you very much for your effort! I'll keep this in mind and if this behaviour will keep annoying me I'll deactivate secure boot :slight_smile:

So, it doesn't look like this?

yes, there is only the password fielt without a gear near to the fielt or anywhere else on the lockscreen :confused:

First, I tried to upgrade from 17 to 18 which was I mistake because it "bricked" the OS that much that I couldn't login no longer- I got everytime after the logging in exactly this "a problem has occured"-message.

So I installed Zorin 18 Core "from scratch".

And You used the ''Erase disk'' Option for the Installation, yes?

Okay, let's check the Following. Got to the File /etc/gdm3/custom.conf and check if it looks like this:

just the basic "write it over the old data"- but not the "deep disk wiping"- because I have a SSD and it was already encrypted with LUKS.

cat /etc/gdm3/custom.conf 
# GDM configuration storage
#
# See /usr/share/gdm/gdm.schemas for a list of available options.

[daemon]
# Uncomment the line below to force the login screen to use Xorg
WaylandEnable=false

# Enabling automatic login
#  AutomaticLoginEnable = true
#  AutomaticLogin = user1

# Enabling timed login
#  TimedLoginEnable = true
#  TimedLogin = user1
#  TimedLoginDelay = 10

[security]

[xdmcp]

[chooser]

[debug]
# Uncomment the line below to turn on debugging
# More verbose logs
# Additionally lets the X server dump core if it crashes
#Enable=true

Could You install Gparted with the Command sudo apt install gparted and make a Screenshot of Your Partitions please? And is the encrypted SSD the one with Zorin on it?

And here is the Reason why You don't have the Choice. Wayland is disabled.

is it something I can enable on the fly? or is it risky to change it manually?

Enter in terminal

sudo nano /etc/gdm3/custom.conf

Change the line
WaylandEnable=false
into
# WaylandEnable=false

Press ctrl+o, then enter, then ctrl+x

sudo systemctl restart gdm3

of corse it was a user problem :grin:
Now I remember: After installing Zorin 18 I realized, that custom keyboard shortcuts didn't work with flameshot and I found a solution, where someone wrote that you can switch back to X11 and everything works fine.

Thats the reason why I switched back- and maybe the reason for this problems and maybe some other problems like this Dynamic taskbar returning back to static after some time too :man_facepalming:

Now I found another solution to solve the screenshot problem Flameshot Print Button not working on Zorin 18 - Solution and will stay on wayland. maybe this solves this problem, I'll have an eye on that :slight_smile:

Thank you all very much for your help!
