Hi Guys,

Totally new to linux and decided to start with fedora. I have a Dell XPS 13 and older Samsung TV, which I use as a primary display when working from my desk. I currently have the laptop dual booting but hoping to get rid of the windows partition soon as the hd is only 128GB. The TV still works perfect with windows at a resolution of 1920 x 1080. I'm using a USB C hub to HDMI out to the TV.

When I boot up in fedora and go into my display settings when I select 1920 x 1080 resolution the output to the TV shuts off completely, however it does work with some other resolutions which are not ideal. The computer is also recognising the TV as only 7" which could be part of the issue?

I'm working on my tech literacy but confused as to what to do next (look for a different display driver?) I've read about some similar issues on this form but couldn't find a solution I could follow.



further info:

"xandr -q" in terminal returned the following:

Screen 0: minimum 320 x 200, current 2752 x 1080, maximum 8192 x 8192 XWAYLAND0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 290mm x 170mm 1920x1080 59.88+ XWAYLAND3 connected 832x624+1920+0 (normal left inverted right x axis y axis) 160mm x 90mm 832x624 74.49+

"lspci | grep 'VGA\|3D'" in terminal returned the following:

00:02.0 VGA compatible controller: Intel Corporation HD Graphics 520 (rev 07)

What's model of your USB-C - HDMI adapter?

It seems that Dell doesn't officially support it for Linux users. Check dmesg output for errors after plugging in the adapter and TV.

also, see if xorg works instead of wayland, could be an issue with wayland.

Thanks ozeszty there are errors coming up with dmesg but they are the same when I run it with the adapter unplugged. Should I post the full return here?

steveebey73742 after searching online it looks like I should be able to select xorg at login but I can't seem to find that option.

tried using the below to switch to xorg:

gdbus call --system --dest org.freedesktop.Accounts --object-path /org/freedesktop/Accounts/User"$(id -u)" --method org.freedesktop.Accounts.User.SetXSession "gnome-xorg"

not sure if it worked but the monitor issue is the same.

Apologies for my tech illiteracy!
