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.

Is there any way to un-freeze my device when it freezes, without shutting down and losing my work? (lemmy.blahaj.zone)

I'm using an XPS 13 9350 with 16GB of RAM and the Intel Graphics 540. I am using Fedora KDE spin. When I am using computer, either randomly or when I start a program, my computer will slow down and quickly fully freeze. In this state, the only thing I can do is shut it down. Is there any way to make it so that a program is killed, or something else that doesn't fully stop my system?

Once fully frozen, it's not really able to be saved.

Is it a full freeze? Press CAPS-LOCK or NUM-LOCK to see if the hardware is still responding.

If it is, it might just be a DE freeze. Try to SSH into into your frozen device, from another PC or phone.

Or press CTRL-ALT-F7 to see if you can switch to a terminal and login.

Once in, use ps -ef, or top to see and kill what might be causing a freeze.

Turn on auto-save in LibreOffice(you usually only lose a sentence or 3 words with this on).

Investigate IDEs with auto-backup or an autosaved change-history.

To diagnose whether you have bad RAM, boot from a LiveUSB distro and use it for a day or week.

If no freezes, reinstall a fresh OS.

If it still freezes, get new RAM, or replace whole PC/laptop.

I super appreciate the comment, as I've had the same issue and didn't know how to deal with it without a full reboot. If there an equivalent command in Linux for what control Alt delete does in Windows?

People are mentioning 'OOM Killer' which may have similar features, I have not tried it out.
