Hello!
I bought myself a USB hub to be able to transform my laptop into a workstation by plugging in a keyboard, a mouse, speakers and a second screen, which does not connect via HDMI but via VGA. The station itself plugs into the computer via USB C. My computer doesn’t have a VGA port so I can’t try to plug it in directly.
The keyboard, mouse and speakers work perfectly, but the screen is not recognized. I tried to restart the computer with the screen plugged in, without success. Something happens when I plug it in (if it’s on standby, the screen lights up and displays “no video input” before going back to standby), so the station is apparently working, thus I imagined that it was a driver problem.
However, when I typed lspci -k | grep -EA3 'VGA'
in the terminal, and it says:
00:02.0 VGA compatible controller: Intel Corporation CometLake-U GT2 [UHD Graphics] (rev 02)
Subsystem: CLEVO/KAPOK Computer CometLake-U GT2 [UHD Graphics]
Kernel driver in use: i915
Kernel modules: i915
If I understand correctly, there is in fact a working driver for VGA. Is the problem in the VGA to USB C conversion? What to do in this case ?
Thanks a lot for your help !
