Damn. So removed nomodeset from grub.

Boots up - at the spinning wheel, the display is shown on the TV.
But I get a crap ton of AMD-Vi: Completion-Wait loop timed out
do_IEQ: 1.36 no irq handler for vector
and
systemd-journald[363] Failed to rotate (or failed to write entry)....

Booted back, put back in nomodeset, and now back to booting to just black screen :(

Okay can you try the same process using this command

Code: [Select]
sudo udevadm monitor --debug

That gave invalid option --debug.. looks like I had to do
sudo udevadm --debug monitor  ?

Still nothing displayed :(

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..

This desktop had similar problems, I had help on this forum and Ubuntu forums, the members here solved it.
Here are the links to the threads so you can compared it to what you had to do to see if there is any info that may help.
Once done I have not had any problems since.
Eventually the Linux Kernel hardware headers will have support for the card, and then I will get a less blurry desktop etc.

unplug the hdmi cable from the laptop, leave it plugged in to the tv.

Open your terminal and type -

Code: [Select]
sudo udevadm monitor
enter 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.

Only one HDMI port.. Plugged it in for 20 seconds, unplugged it. No messages displayed.

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=1613132

Based 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.

Nope. Tested cable with another device and used a different cable that worked (on a nintendo switch), no go.

Not sure if it makes a difference - I boot with nomodeset as a kernel param - that's not affecting it is it?

Have you tried another HDMI cable to rule that out ?

God I'l laugh if it's that simple.. Pretty sure this one worked last I used it, but let me see if I can find another one or swap some things around and try.

Okay, in Menu>Settings Display
Have you checked the "mirror" setting ?

There's no options. http://www.espphotography.com/display.jpg   

The Default drop down has no choices in it.

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.

Sorry, no - other way around. Want PC to show on television, ie as an external monitor.
