Hmm, I've got a system that's done something like that, too. For about the last two years. It would apparently crash while playing a video file, every now and then, and almost nothing could reset the system. I couldn't trigger the fault on demand, it just happened sometimes. I did try SSHing in from another PC, but got no response. Later I discovered the monitor was faulty. It didn't like being cold, and would freeze with a similar looking messed up screen, until it warmed up. And only had something like the title bar, and a tiny bit more below it, showing actual video content. Or, on a plain terminal, you'd just manage to see the logon and password prompt. Though sometimes the whole screen was stuffed. You'd think the PC wasn't responding to commands, but the screen wasn't showing what was going on. Now, I can't remember if I tried SSHing before trying to reboot the PC. CTRL+ALT+DEL often results in lengthy system hangs, any time that I try it. So it could have quite easily been running fine, behind the scenes, then wedged itself when I tried to force it to reboot. And I could have only tried SSHing in at that point. My favoured response to apparent desktop crashes has become to hit CTRL+ALT+BACKSPACE to reset the X server (the preference has to be enabled for this, it's usually disabled). It's better at instant results. Another point to consider with crashing systems, is to check the CPU cooling is okay. The fan spins, the heatsink isn't full of fluff, and is firmly seated on the CPU. Or bad RAM. I had a PC with bad RAM that I only found out by running memcheck86. It just happened to be that for many years when the system booted up it must have put something completely unimportant into that part of the RAM. At some later date, and an update, the system would frequently crash. But going back to an older version, and it would run. -- uname -rsvp Linux 3.10.0-1160.119.1.el7.x86_64 #1 SMP Tue Jun 4 14:43:51 UTC 2024 x86_64 (yes, this is the output from uname for this PC when I posted) Boilerplate: All unexpected mail to my mailbox is automatically deleted.
