Okay can you try the same process using this commandCode: [Select]sudo udevadm monitor --debug
sudo udevadm monitor --debug
Well, this laptop has been a PITA. This was really the second *nix o/s I could get installed. Tried a dozen others, all crashed at some point during install or boot. Was able to get this installed, but wouldn't boot (to a display). I have the error written somewhere, but googling it said to add nomodeset. I'll see if I can find the error, maybe you have a different idea, but without nomodeset, I get a black screen on boot, nothing else..
unplug the hdmi cable from the laptop, leave it plugged in to the tv.Open your terminal and type -Code: [Select]sudo udevadm monitorenter your password when asked.Plug the HDMI cable in to your laptop hdmi port, then unplug it from the laptop hdmi port.Post the resulting terminal message in your reply.If your laptop has more than one HDMI port repeat this in each port.
sudo udevadm monitor
I am not positive."Adding the nomodeset parameter instructs the kernel to not load video drivers and use BIOS modes instead until X is loaded."https://ubuntuforums.org/showthread.php?t=1613132Based on this, it seems once the desktop is loaded it would not be in use. From the other replies it shows how the commands discussed can affect a range of hardware after boot.
Have you tried another HDMI cable to rule that out ?
Okay, in Menu>Settings DisplayHave you checked the "mirror" setting ?
It sounds like you are asking how to output the tv/stream it, to the laptop, so the laptop screen shows the tv ?You may need a TV capture card for this.Another way is you can install Kodi from Menu>System>Lite Software to watch tv and not need your laptop to be attached to the tv.
