Randomly on my laptop screen this appears and debian just freezes. Sometimes these vertical lines don’t appear and system freezes anyway. Its just random. How do i identify if this is hardware or software issue? and then how to identify exact piece of hardware or software causing this problem.

    RAM or Video card issue. Are you SURE the entire machine actually locks up, or just the display? Try ssh’ing into the machine when this happens to see if it’s actually staying alive, though the display stops working.

    Idk how useful this is but that looks like when i had bad RAM, or like when RAM becomes unseated. You could try reseating your RAM, YMMV.

          Hmmm. I have also installed linux mint xfce from scratch. So far so good. It stuck only one time since this install. And its been 5 days or so i guess.

    I have a similar issue specific to my Intel graphics, debian 12, and kde. It’s fixed in the newer kernel in debian Trixie. In my case I was able to set up a keybind to ctrl-alt-backspace which kills the graphics server. I have to catch it quick or it’ll lock up completely, but it’s something to try. I’m on 15 days uptime now I’ve probably had to do that about 5 times.

        Np. Trying to find the exact page but I just checked the last logs in journalctl after each crash to determine that’s what it was. If you search Wayland + kwin + Intel GPU crash you get lots of hits. It can be fixed but now that I know it’s very specific to my setup and already fixed in future versions I’m not so worried.
