I have recently installed Kubuntu 22.04 (kernel version 5.19.0-40 generic) in Dual Boot with Windows on my HP envy-13.
My problem is that Kubuntu works only when my second monitor is plugged into laptop through a USB-C to VGA adapter. When the second monitor is not plugged in kubuntu won't boot and when I unplug it during a working session my laptop totally freezes and I have to turn it off manually.
On the other hand Windows boots perfectly on my laptop.
Do you have any idea of the source of this?
Thanks in advance,
