Title: No display on HDMI out
Post by: phirephoto on October 18, 2018, 12:17:37 AM
So not sure if this is the right category, but I have HP laptop, AMD GPU, AMD CPU, HP 17-ak001ds . I've connected my TV to the HDMI out on the laptop, but can't get LL to recognize it.
Linux Lite 4.0 (GNU/Linux 4.15.0-36-generic x86_64)

Any suggestions on what to try?

Thanks :)

Connect the TV and Laptop together. Make sure the TV has the right HDMI source. Reboot the Laptop. Open up settings and find >Display. There should be two displays listed. Select the TV display. You may have to adjust the resolution to suit you.

Yep, TV is selected to the right input, rebooted with HDMI connected, Display shows only the laptop. :(

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.

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

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.

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?

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.

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.

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.

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.

Still nothing displayed :(

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 :(

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

Looks like a common occurrence..
May want to a different kernel.. Perhaps 4.13?? See last link...

Lite Tweaks > Kernel Installer, you may have to choose at boot - from Grub choose advanced options select 4.13 continue boot... Test... If no difference can try others, to go back to 4.15 -- from Grub choose advanced options select 4.15


Lots of 18.04 and HDMI

I did a fresh install. It was a pretty new install, so this was easier. But back to no HDMI with nomodeset :(

Same no output with different kernels??


Have you checked "Update Drivers" to see if any additional drivers available - or trying "not use"..??..


Some additional thoughts...

If addition drivers are available - I think there is an option to not use or not use proprietary or some phrasing - I'm not on my LL box..

What has been the results of different kernels (not drivers)?
- Some work better than others depending on the hardware...

I would try 4.10 and may be even 4.4 (LL3.x ran with this kernel) which is what I run on my mini.

If you've looked through https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1761751 (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1761751) they're are folks that say 4.13 and older have worked.. Or with Kernel options similar as amdgpu.cik_support=1 radeon.cik_support=0 amdgpu.dc=0

Also may want to look here: https://linuxconfig.org/how-to-install-the-latest-amd-radeon-drivers-on-ubuntu-18-04-bionic-beaver-linux
You'll want to ensure there is an Ubuntu 18.04 version..


What version of AMD Radeon are you running may aide with others chiming in...

Ok, so .. I have LinuxLite on two laptops. I think the HP is hopeless for this, LOL.. Other laptop is a Acer Aspire Timeline. https://en.wikipedia.org/wiki/Acer_Aspire_Timeline  Yeah, I know, old laptop, but it's lightweight and basically brand new, was sitting in a box for a while LOL. So, it runs fine, no need for nomodeset on it. I get HDMI out, but not getting any audio on the HDMI out. Went to audio out, and tried all the output settings, dolby 5.1, 7.1, etc. No go. Should that work? Outputting HDMI to my TV? I do get video, just no sound. Yes, I get sound via the pc speakers when I select PC audio out...

My old  AMD Toshi laptop running on kernel 4.13 with Ubuntu 16.04 actually runs perfectly with HDMI. Watch Netflix, MLB network etc. No issues once Firefox is configured for it. Might be the ticket for you. It does show both interfaces correctly i/e onboard/TV in the settings as well, and it dual boots UEFI with Windows 10 so I'm not likely to change it anytime soon. I am skeptical though, that Ubuntu 18.04 with the newest kernel wouldn't work as well. Users tend to jump ship pretty quickly sometimes, perhaps during upgrades not noting changes to video and/or sound card drivers, etc. Drivers can be reverted after upgrades done properly. Part of the problem is there is no upgrade path between LL 3.x and LL 4.x even though there is between Ubuntu 16.04 and 18.04.
*By the way the TV remote control should still control the volume.

And it randomly started working.... That's odd.

To clarify - the Acer, sound. Still nothing on the HP, but I think I'll give up on that one. :(

It is possible that the HDMI port has been damaged and is defective. When connected to a display via HDMI, does the display detect something attached to it via that particular HDMI source.

Just a hint to help others. I had a problem with the HDMI cable ver.1.4 and replaced it with version 2.1, as the bandwidth of  old cable was not enough. Then Had to adjust the resolution on TV down from 1920 to 1028 to match video card. My 55 in TV is working with the PC now with a 9200 ATI video card on HDMI 2.1 version cable.
