Hello, I installed Fedora 34 on my Acer Swift 1 SF114-32, today I tried to plug an external monitor into the built-in HDMI port: suddently both the laptop and external monitor screens went black, as they received a totally black signal from VGA. The only way to recover from this status is to hard reset the laptop with the standard power on button; however if I plug the monitor before booting the system everything works perfectly.
I’m running latest kernel version 5.11.19 but even with 5.9.0 this problem persists, I also tried with both Wayland and X.org Sessions of Gnome and this didn’t make any difference.
These are last lines of system log before the hard reset:
