I recently installed Ubuntu 22.04 onto my new PC. Everything works well except when I suspend the system and try to turn it back on, my monitor is just black, and the keyboard/mouse doesn't work, so the only way to get back in is to restart my PC. I've looked online and tried this, as well as changing Wayland to X11, neither of which worked and nothing else I have found seems to work. My PC runs Intel I5-12500 and doesn't have a GPU, so it uses Intel's integrated graphics. Kernel version: Linux 5.15.0-41-generic x86_64.

I'm new to Linux, so any help would be appreciated! Thanks

  • Thanks for the quick response. I have an Auros motherboard. Will this still work? If so, do you know how I can disable it, I couldn't seem to find anything on it in the BIOS. I'm also running a virtual machine within Linux, so will this stop working if I disable IOMMU? – NZ_0 Jul 26 '22 at 02:29
