on bug 112288
from Peter D.
All three ports work. If my computer boots to a blank screen, plugging in a second monitor "resets" the video and both screens display the desktop as clones. There are two monitors; a slow one with a maximum vertical refresh rate of 75 Hz, and a fast one with a maximum vertical refresh rate of 144 Hz. The fast monitor has DP, HDMI and VGA ports. The slow monitor has VGA and DVI ports. The motherboard has DP, HDMI, and VGA ports. Currently there are cables that can reach ... MoBo DP fast monitor Mobo HDMI (passive adapter) DVI slow monitor Mobo VGA slow monitor This can be rearranged if need be. The reset trick has happened with; the slow monitor plugged into the VGA port and being revived when the fast monitor was plugged into the DP, and with the fast monitor plugged into the DP and being revived when the slow monitor was plugged into the HDMI port. Currently using a mainline kernel downloaded from Ubuntu. psd@EE:~$ uname -a Linux EE 5.4.0-050400rc7-generic #201911102031 SMP Mon Nov 11 01:34:23 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux psd@EE:~$
