Recommended CLI Commands to Execute for Error Log?

[OzarkJoe]

I'm running Linux Lite 6.0 rc. Everything has been going fine until I played around too much. I made some changes in the display UI and my laptop froze. Upon reboot it sent me to the infamous login loop. I used Ctrl+Alt+F2 and was able to successfully login - username and password worked. Account/credentials are good. I'm now at the CLI.

As mentioned above this seems to be set off by me playing with the graphics settings.

Here’s the question... What commands do I need to run that will help diagnose the problem?

Thank you.

Joe

Update...

I booted from the Linux Lite 6.0 USB Stick install source. Once I was at the trial version desktop went to my system snapshots and I'm installing my first clean setup from there.

Once the snapshot is complete I'll report back my results.

I'm also gathering all the CLI tutorials I can find. I may not know the answers, but I'll know where to find them.

Thanks.

Nope, that didn't fix my login problem. My laptop returned to the same username/password page as before. It should automatically login. The boot loops continue.

I'm not that far in to do a complete new/fresh install.

If you reverted a snapshot or backup?? was that prior to setting auto login?
When you log on is this a normal login or a tty session (Ctrl+Alt+F2) ... To exit or return to GUI try -  Ctrl+Alt+F7 ..
- Should you attempt to undo or fix via the tty...
Might be worth a try log in and set up auto login again??

Trying to understand the issue a bit more.

I made some changes in the display UI

What tweaks were done just before the machine froze.

Upon reboot it sent me to the infamous login loop

A description of what happens might help.

went to my system snapshots and I'm installing my first clean setup from there'

Is this using Timeshift aka System Restore Utility or DejaDup aka Backups or something else

Just a suggestion, but  after logging in to the tty via ctrl+alt+f2 maybe try the command

Code:

startx

Followed by return and post the result with any error messages

A) I changed the desktop display settings. Display > Scale: 1x (changed to 2x) > clicked apply. System froze and the only option was to do a hard reboot (press power button until the laptop power goes off).

B) After the above mentioned forced reboot, I did a search of the Linux Lite forum for issues where the auto-login is ignored and boots to the user account and password login... (selecting my username and entering my password followed by clicking enter) sends the user back to the same page. This is where I discovered the Ctrl+Alt+F2 feature.

C) I used the pre-installed Timeshift/Snapshot creation application (labeled: System Restore Utility) and applied the first RSYNC restore point I created immediately after the 6.0 install. The restore point was before any changes were made.

D) No need to proceed further with running startx. I did a fresh re-install of 6.0 and I'm back to an error free load. But, just in case... I'm saving a Timeshift/Snapshot of my fresh install.

Thank you for letting us know.

I'd guess the display scaling change just affected the logged in user's personal desktop and so would probably have been saved in the user's home directory in the normally hidden sub-directories.

Home directories are excluded for backing up under Timeshift default settings.  This could explain why the restore left you in the same place.

Home directories (including hidden) are included for backup by by dejadup (aka Backups) with default settings - though it's not particularly easy to revert a change like this from a backup set.

Ideally there would be a 'Automatically revert changes in 15 seconds' type of confirmation after applying the change to reduce the chances of getting stuck.

I was expecting the auto-change/auto-revert action to occur. But it just froze.

Thanks for the information. I'm learning something every day. I'm trying to keep this 63 year old brain active. It's a chore considering what I did to it in the 1980s. [emoji2960]

I've received a few beginner and command line books I'm looking forward to digging into.
