Motherboard: Biostar x370gtn – bios latest
Gpu: Gigabyte 2060 super
Monitor: Asus mb16ac (usb-c) & some aoc (hdmi), both plugged in.
Os: Xubuntu 19.10 / Win10
Temporary solution:
When I unplug and replug the usb-c monitor from the gpu everything starts working.
Issues:
1)Most times on boot up, my motherboard reaches the final post code (99), and hangs.
2)Some other times grub does load, but lands me on a completely blank screen, even pinging the desktop doesn’t work.
Notes:
- In the first issue, I know the computer hangs on post, because if I press delete and unplug the monitor, I land in BIOS.
- In the second issue, when I unplug the monitor my ps/2 kb(numpad led) and usb mouse turn off and back on.
- When only one monitor is plugged in (only the hdmi or only the type-c) everything runs fine so far (I need to do more testing on this).
- This is a dual boot system, windows boots up without a hiccup.
