Re: No display on HDMI out - bitsnpcs - 10-18-2018
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."

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.
Re: No display on HDMI out - bitsnpcs - 10-18-2018
unplug the hdmi cable from the laptop, leave it plugged in to the tv.
Open your terminal and type -
Code:
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.

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..

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

Okay can you try the same process using this command

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.

That gave invalid option --debug.. looks like I had to do
sudo udevadm --debug monitor ?
Still nothing displayed
Re: No display on HDMI out - phirephoto - 10-19-2018
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
Re: No display on HDMI out - bitsnpcs - 10-19-2018
Have you tried removing nomodeset and removing the hdmi cable from the hdmi port, booting the computer, to the desktop then putting the hdmi cable in to the port ?
So the graphics driver loads fully first.

Yeah, without nomodeset I wouldn't get a desktop.. Now with nomodeset, I get actually the black screen with the feather background - nothing past that. No HDMI cable in
