Screen won't turn on after auto logout

Hi guys, I installed Fedora a few days ago. It's been working great, except for one problem: when I leave my computer by itself long enough for it to auto log out, the screen turns into the same grey color as the background for the boot animation, but there are a few lines going across it (it didn't display correctly). The only way I have been able to recover from it is by doing a hard shut down.

Welcome to ask.fedora! I'm not sure just what you mean by auto-logout, because I've never heard of Linux having that feature. I'm not sure, but you may be referring to the fact that by default the screensaver locks the screen when it blanks it. If so, you should be able to disable that in the screensaver settings. If not, there are ways to regain control if you're locked out that badly, as long as the system isn't completely hung.

I looked at power and background settings thinking there might be a display setting that would keep power on after lockdown, causing heat build up in the display. No joy. I would investigate mechanical heat sources; fan operation, BIOS settings, etc.

Sorry, by auto log out I meant entering sleep mode. I have been able to avoid the problem by having the screen lock instead of entering sleep mode, but it still happens when I enter sleep mode.

A shot in the dark, try disabling plymuouth (the boot splash):

  • At the GRUB, the boot loader, screen press e to edit the menu entry

  • Look for the line that starts with linux, remove rhgb quiet and add plymouth.enable=0

  • Press Ctrl+x to boot
