The best I can suggest is look into the NVidia Optimus driver. https://wiki.archlinux.org/index.php/NVIDIA_Optimus

The port is possibly disabled via driver.

The way the nvidia/intel GPU are laid out in laptop has some funky architecture, with one GPU controlling the HDMI ports and the other controlling the LVDS output of the flat panel. This architecture has been a headache for the VFIO/gpu passthrough crowd.

  • how can I install this drivers ? – Abe Sep 29 at 16:35
  • I don't know anything about Deepin Linux. You indicated that it works with Elementary OS and Ubuntu. This suggests a driver issue and might want to start your search there. What does Deepin do differently from Ubuntu or Elementary. – MadVocoder42 Sep 29 at 17:13
  • I've already use Ubuntu and ElementaryOS, both OS hdmi works find (ElementaryOS got some issues, but it was easy to solve). Deepin is Debian based, so it should work fine as long as it works on Debian. – Abe Sep 29 at 17:29
  • Its Debian based, but not Debian. Just like Kubuntu is Ubuntu, but its not Ubuntu. There are similarities but not necessarily the same. Find out what drivers you have and whether or not they are active. You need to determine what drivers are installed, what version they are and whether or not they are running. – MadVocoder42 Sep 29 at 19:20

Can you paste the output of xrandr --verbose

If the HDMI output shows up like you can add the display manually:

xrandr --newmode $(cvt 1920 1080 60.00 | grep Mode | sed -e 's/.*"/1920x1080my/')
xrandr --addmode HDMI-1 1920x1080my
xrandr --output HDMI-1 --mode 1920x1080my
| improve this answer | |
  • I have virtually the same issue. I have performed the steps as instructed, as the make sense. The only problem is that now it still says the port is disconnected. (The mode was properly applied): HDMI-1 disconnected 1600x900+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1920x1080my 59.96 1600x900my 59.95* There is a monitor connected to this port, that is working through this port on my Windows dual boot. – Uncle Snail Sep 26 at 5:17
  • try this sudo ubuntu-drivers devices sudo ubuntu-drivers autoinstall .... also sudo prime-select nvidia | intel – oat Sep 26 at 8:59
  • I've tried to add manually and still not working, by listing with --verbose flag, output prints only eDP-1 config. I had remove Deepin OS from my pc but i'll install again. – Abe Sep 28 at 16:56
  • @oat i just added xrandr verbose – Abe Sep 29 at 1:01
  • @oat when i try to run xrandr --addmode HDMI-1 1920x1080my i got this error xrandr: cannot find output "HDMI-1" – Abe Sep 29 at 1:03
