Why does desktop Linux (openSUSE) freeze (hang)?

Question

linux

Good day.
openSUSE LEAP 42.3 x86_64
2gb RAM
At random (relatively) times, the system completely freezes: the screen freezes, the keyboard and mouse stop working. The only way out is to restart the PC. Such freezes can be either 3 minutes after starting the computer, or 2 hours later. It happens that with a heavy load there are no such freezes, but it happens that they appear even with a minimum load.
What could be the matter and how to fix it?
It is difficult to connect them with something, but I can clarify (not the fact that this is precisely because of this) that several times I observed a freeze when I first opened a site in Google Chrome, and a certain number of seconds of visiting passed on this site. But there was also a freeze when the desktop with widgets was simply displayed. I also observed several times freezing while scrolling with the mouse wheel on the site.

Answer 1

Look at the system logs, dmesg.
it happened to me when the ssd disk died due to timeouts, although the check showed that everything was ok with it ...

Answer 2

I had this, I sat on Debian for several years because of this. he showed himself just fine - there were no freezes at all.
Solution:
I got up dead on my laptop with Intel guts on 16.04, and searched for a problem for a long time until I found this: ... “If it hangs tightly on distra higher than 14.04.3, then 99% that this is due to Intel graphics. I had regular freezes after 20 - 40 - 90 min. It was decided so sudo gedit /etc/default/grub bring the line GRUB_MDLINE_LINUX_DEFAULT to the following form (if nothing was added) GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_idle.max_cstate=1" Save, close. sudo update-grub And reboot. The problem should disappear if Intel HD is to blame. "... IT HELPED ME. I specifically drove for a week without reloading the video in the chrome browser.
