Binary package hint: xorg
Unfortunately, I can't really provide much more information...
After I've been logged in for a while (usually at least a day), the display may suddenly go mostly black with a few random horizontal lines (looks kind of like if the output frequency is completely wrong). If I'm using a connected display, rather than the laptop screen, it loses all signal and asks me to check the cable.
The only fix I've found is to reboot. I am able to switch to virtual terminal 1 (Ctrl+Alt+F1). The display there is also corrupted, although some text will show up (generally in the lower right corner, but it does not display everything; the most recent lines are not included there, but it will scroll). I log in as myself and sudo reboot. Obviously, everything is back to normal when the OS finished booting.
