Dark screen on reboot following GRUB menu

[MarkGNY]

I stumbled on an issue:
I noticed during a normal use of Zorin, it began to misbehave, for example, starting an app and nothing happening. I rebooted and it would just hang with a black screen.
Searched for similar issues and only found some references to bad drivers.
It turned out that my system partition was 100% full. I extended it and this cleared the issue.
I'm puzzled why the OS had not warned me, but just stopped functioning.

Yes, there is unfortunately no warning in such a case. You can look if your logs filled the drive and limit the space for log files:

How to limit the size of syslog to save storage space

Now I just had an issue with LibreWolf spewing errors like no tomorrow and filling up my syslog file to a whooping file size of over 200GB. [image] As shown in the picture you can find your syslog file under /var/log. Here's how can get started on limiting the file size of the syslog. Open your terminal and run this command so we can edit rsyslog which is a file that deals with how syslog is handled. This doesn't limit the file of syslog but the size of the rotating files. sudo gedit /etc/lo…

As an alternative solution you can set
"sudo journalctl --vacuum-size=200M"

To check the disk usage enter in terminal:
"journalctl --disk-usage"
"sudo du -h /var/log"

or you can use the app "disks" which is installed to show how your disk space is used.

Sometimes log errors fill the complete disk.

If you want you can use tools for system cleaning up like stacer, ubuntu cleaner or bleachbit.

When you have a small disk with little storage space, it is recommended to prefer native Zorin (deb/apt) packages. Flatpaks and snaps run in a sandbox and bring with their whole dependencies and inflate the system.
