What are the ways to stabilize processes in linux?

Question

linux

That's how many years I've been working on the line, so it's constantly hanging processes. You watch a video on YouTube or in Excel, and nothing changes on the screen except for the arrow. Even when you switch to terminal mode, you just have a black screen, you don’t even have a cursor to htop open and close hung processes. You no longer know what to do with it, except to simply turn off the computer and turn it on again. After all, I may not have saved documents, but I just took and turned off the computer. Tell me how to work with such processes.

Answer 1

You say something strange. Do you have iron in general? memtest?
sysrq alive? Most likely alive, since you can switch to tty. See what the kernel says https://en.wikipedia.org/wiki/Magic_SysRq_key

Answer 2

I had a similar experience when my RAM was running low. At the same time, the axis sharply tried to write to the swap, which, together with the rest of the load, could cause the laptop to hang. But with the screen everything was fine.
Here, a jamb with firewood sleep modes of the video card is also possible, for example.

Answer 3

upgrade to the latest kernel,
switch to another distribution,
it may be video firewood.
no_telepat_mode

Answer 4

Do you have something with hardware or OS. I'm afraid you're trying to solve the problem from the wrong side.
For many years now, I have not observed such behavior on any of the operating systems used (and have not heard of such a thing, too, for a sufficient amount of time).
Try to check the disk and memory, most likely the problem is somewhere there. (well, reinstalling the system on a stable LTS distribution would not hurt)

Answer 5

Personally, this happens to me extremely rarely, taking into account the work of highly resource-demanding programs.
Maybe something is wrong with the system itself? Proc / firewood, etc.
Set up load monitoring and look at the logs - maybe the system writes itself.
Usually I switch to another terminal and calmly cut off the process.
