Title:
Black Screen After A Few Minutes
Status in linux package in Ubuntu:
Confirmed
Bug description:
I first encountered the issue on Kubuntu 18.04 when I removed my 2nd monitor,
the screen went black after 5-30 seconds. I tried:
- disconnecting the 1st instead of the 2nd monitor
- using Ubuntu 18.04 (not Kubuntu)
- using Wayland
- installing the latest mainline linux kernel 4.19rc4
The only things that worked so far are:
- Having both Monitors connected
- nomodeset or recovery mode
- using Ubuntu Gnome 16.04
- loggin via tty/terminal
When the PC was turned off for a while, I have to wait for a few minutes or
start lots of applications for the black screen to occur. If the PC was
restarted several times due to this bug, a blank screen may occur as soon as I
see the login screen.
The issue also occurs during installation when autodetecting the keyboard
type or after selecting the installation type (Minimal Installation or Normal
Installation etc.)
My Hardware:
- ASRock H87 Pro4
- Intel i5-4570
- AMD Radeon R9 390
- 1st Monitor connected via DisplayPort to HDMI adapter cable (or DVI-D)
- 2nd Monitor connected via DVI-D cable
