External display is no longer detected

Hi,

Yesterday my laptop (XPS) stopped detecting my display (DisplayPort) and I don't know why. I've spent a lot of time trying to figure it out but I'm kinda desperate right now. It was working fine.

xrandr:

Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767
eDP1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 290mm x 160mm
   1920x1080     60.03*+  48.03
DP1 disconnected (normal left inverted right x axis y axis)
DP2 disconnected (normal left inverted right x axis y axis)
VIRTUAL1 disconnected (normal left inverted right x axis y axis)

lspci | grep VGA

00:02.0 VGA compatible controller: Intel Corporation UHD Graphics 620 (Whiskey Lake) (rev 02)

cat .local/share/xorg/Xorg.0.log: https://pastebin.com/PxCCNmye
dmesg: https://pastebin.com/xtcaWugZ

I would appreciate any help.

Thanks!

Re: External display is no longer detected

What do Fn+F7/F8 do? Looks like an output toggle?
(There's nothing like a link training error or similar in the dmesg)
