[SOLVED] Unable to use external monitor (HDMI) on my HP G7 with AMD

blueleaf · 2021-03-06 14:49:15

Hi all,

Few days ago I’ve switched to a new laptop and installed Arch (with Cinnamon as a DE), laptop is AMD based (Ryzen 3500u and Vega 8 iGPU). The problem is that I can’t connect an external monitor to HDMI, it doesn’t work. The laptop's screen starts flickering regularly and that’s it. The external monitor doesn’t react at all (it's recognized though). I’m at odds on what to do, read a lot of topics but can’t seem to find a solution as most are related to hybrid laptops which mine is not. It's AMD CPU and GPU (integrated), without dedicated graphics.

BTW, the problem is not with a port as I've tried the monitor on Windows and it works perfectly well.

I've tried switching kernels but that didn't help either.

Here's some more info:

This is the xrandr output when the external screen is connected and showing nothing and my laptop's screen is flickering at regular intervals. The laptop becomes barely usable when connected to HDMI because of this flickering and cursor changing positions. However, the miracle happened yesterday and I was able to use the external monitor for about 10 mins. (until I restarted the system).

Full journacltl -b | grep -v audit (run as root) and xorg log please .

Is xf86-video-amdgpu installed ?

Hi, thank you for your response.

Here's the journal log:
https://pastebin.com/M09SzDLV

And the xorg log:
https://pastebin.com/jJfRntR1

xf86-video-amdgpu is installed and running.

Herer's a short video of what happens when I connect the external monitor. As you can see, it's properly recognized by the system but that's about it.

The xorg log is weird and way to short, you also have kvm disabled in firmware which usually is a bad idea on amd processors.

Those things can wait however as the core dumps indicate there's a bigger problem : a race condition .

The first line shows when systemd thinks your system is ready to do graphical stuff .
Last line of that block shows when your videocard starts initialising .
Basically applications want to use the full capabilities fo the videocard before it has finished starting up and this causes many problems.

Configure your system to use https://wiki.archlinux.org/index.php/Ke … _KMS_start .

Thanks for your help!

I've enabled virtualization in BIOS and then ran

LC_ALL=C lscpu | grep Virtualization

which outputs "AMD-V". Does this mean it's OK now?

Regarding the xorg log, I'd actually looked in the wrong folder, so here's the full log (up until this moment): https://paste.ofcode.org/33bPjN7uuDvvR9dXZUTEKvJ

As per your link, I've also added "amdgpu" to the kernel MODULES line, saved mkinitcpio.conf and updated it through terminal. This actually changed few things: the weird-looking login screen disappeared and I'm no longer requested to enter the password to log in to the system. Another thing is that it solved the problem with screen brightness and the system now remembers the parameters used before shutting down. By the way, I got the following warnings while updating modules:

 
==> WARNING: Possibly missing firmware for module: wd719x
==> WARNING: Possibly missing firmware for module: aic94xx
==> WARNING: Possibly missing firmware for module: xhci_pci

Could this be related to my problem? I've no idea what these are but will look into it.

Anyway, the problem with HDMI persists. I was actually able to use the external monitor (for the second time now!) but it only lasted until I put my laptop to sleep. Upon wakening up, the same old blinking began. I then tried to re-insert the cable several times but it didn't work.

The xorg log recorded the following AMDGPU error:

drmmode_do_crtc_dpms cannot get last vblank counter

.

This error actually seems to be related to external monitor problems. Performed a quick search but so far haven't found any solution. Will keep searching...

lscpu shows what the cpu can do, but not what is actually in use.
Try (as root)

# dmesg | grep iommu

The missing firmware only matters if you have specific hardware.
wd719xx & aic94xx are (expensive) hardware raid controllers that are uncommon even in enterprise server hardware.
The xhci_pci kernel module requires special firmware if you have certain renesas usb devices.

I'm guessing BOE is your HDMI screen ?

What HDMI version do the monitor and cable support ?
Can you try with a different hdmi cable ?

I suppose BOE is my BENQ GW2283 monitor which supports HDMI v.1.4 (confirmed: tried once again to connect it unsuccessfully and the same error showed up right away). The cable I have is v 1.4 as well. I have a replacement cable (the same one) which I've tried but the result is the same. BTW, I use this monitor with the same cable with my old intel Fujitsu laptop on a daily basis (for work, also runs Arch) without any issues whatsoever. It's also a bit strange that sometimes the monitor actually works with this new laptop. I'm at odds on what to do now...

I managed to find a workaround, it's not perfect but it works. It didn't work this way earlier (it might have something to do with the module thing pointed out by Lone_Wolf).

When I connect the cable and the screen starts flashing/flickering, the solution is to suspend the system and wake it up. As simple as that. I get some ugly artifacts upon waking it, however, they disappear soon enough and the external monitor starts working. That's a lot better than nothing, I can live with that I guess. I have to turn on the wifi everytime I wake up the laptop though (only when connected to HDMI)...

Here's the video of how does it look like: https://youtu.be/tr5GNNIhm8Y

Unfortunately, this is a shitty workaround... It's unreliable at best. I had to repeat the suspend-wake cycle for 5 or 6 times until the external monitor started working. Sometimes it works right away, sometimes not. Not sure why is it so. Any further help would be highly appreciated.

So monitor and cable are not the cause.

Remove xf86-video-amdgpu, then restart Xorg(or reboot) so X has to use the modesetting driver.

The result of that should help to narrow down where the error originates.

Hi, sorry for the delay in response!

Thanks for your help. I'm happy to say that the problem was solved after installing recent kernel updates (or was it another update that fixed it? Not entirely sure).
