Bug Description
I've Ubuntu 20 EOAN installed on a Toshiba Satellite laptop. I have connected an external monitor screen connected to the laptop through the HDMI laptop's output. The external monitor only works when I go into the BIOS and select HDMI. However the laptop monitor does not work simultaneously.
The internal monitor only works when I go into the BIOS and select System Monitor. However the HDMI monitor does not work simultaneously.
This is the output of the xrandr command when the HDMI is enabled in the BIOS:
wasadmin@
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1280 x 1024, current 1280 x 1024, maximum 1280 x 1024
default connected primary 1280x1024+0+0 0mm x 0mm
1280x1024 77.00*
wasadmin@
This is the output of the xrandr command when the system monitor is enabled in the BIOS:
wasadmin@
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1366 x 768, current 1366 x 768, maximum 1366 x 768
default connected 1366x768+0+0 0mm x 0mm
1366x768 76.00*
I cannot see any HDMI in the output even when the HDMI BIOS is enabled in the BIOS. Can you help?
