From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

It doesn't matter much what Linux you use. Rather what is your desktop environment? (KDE Plasma, Gnome, sway etc.)
On KDE for example there is a shortcut to restart the compositor, which might fix your issue.
But in general you might have luck "restarting" it by switching the tty. You do that by pressing CTRL + ALT + some function key between F1 and F8 (the standard gui tty number depends on the distro). Try to switch to a non gui tty and then back.
For example, on my distro I would do:
but on yours it might be F7 or some other.
+1 to ctrl-alt-fsomething (start at f1 and go up to move through the different virtual terminals). once in a while there are graphics problems which this will fix.
If you're using GNOME Shell on X you can reload the shell (and all of its extensions) with alt-f2 and then in the "Run a command" dialog that appears type
rand hit enter. Unfortunately this doesn't work in GNOME on Wayland.I agree with Ctrl+Alt+F1/F2 but would add
init 3 init 5
but I learned for my case its better to reboot if my GPU is acting up the instability would eventually come back
the init command probably only works in Debian nowadays givin it's a thing from the sysvinit era
Thanks Zorin OS uses GNOME with Wayland
While these can help on other issues, these will do nothing if the driver has an unrecoverable issue.
And the driver is stuffed if the hardware decides to have an unrecoverable issue.
(I'm looking at you, Intel GuC. You dumb little bastard.)
If the kernel runs into a oops it can recover and you won't notice anything except a nasty looking error in dmesg. If it runs into a panic you need to hard reboot the system as it can't continue to run.
