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.

    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.
