Bug Description

When i do get it to work, on reboot it'll be back to fullhd.
this happens on nvidia 440, 435 and 390.

On X.Org X server it does work.

Graphics card: nVidia GT1030
Amp: Onkyo TX-NR646

On 19.10 there are no problems.
A couple of weeks ago i tested a daily build and there were no troubles also, so this is new.

My favourite setting: 3840x2160 200% 60hz.

I can see two issues:

1. The 4K monitor is not plugged into the Nvidia card. Is that right?

2. The Radeon GPU it is plugged into is refusing some modes (because they're out of range?):

So make sure the monitor is plugged into the correct HDMI port. And if it still doesn't work then please try a different HDMI cable. You will need an HDMI 2.0 cable to achieve those modes.

Hi,

On the videocard a premium hdmi2.0 is plugged in which connects to my hdmi2.0 Onkyo TX-NR646 amp, which acts as a switch for my windows pc and my ubuntu pc's.

The Onkyo hdmi2.0 out is connected to my Philips 49inch 4K TV.
I will try to connect ubuntu 20.04 to my tv directly and report back here this evening.
This however is no solution for me since i have 1 4K screen and two pc's and want my amp to act as the switch for both pc's

So although everything is working fine in windows and ubuntu 19.10;

i swapped my onkyo receiver for a newer Denon hdmi 2.0 receiver - the AVR-X1400H; same issue.
i connected to pc directly to the screen; same issue
i switched to a different brand of premium hdmi 2.0 cable; same issue.

i've also installed the ubuntu budgie flavor beta; same issue.

I think it's pretty safe to say, this not a local hardware issue at this point.

Weird. The XorgLog shows that HDMI is talking to the wrong driver so I assumed that meant it is plugged into the wrong GPU...

Does your computer not have multiple HDMI ports? If not then it looks like there's a problem with how the Nvidia driver is installed here.

- or -

The modeset driver might be refusing high bandwidth modes prematurely?

Can you please attach a photo showing where your HDMI cable is plugged into the computer?

As far as I can tell, if it's plugged into the motherboard then this would not be a bug. It looks like that model of motherboard does not support 4K at 60Hz, but is limited to 24Hz or 30Hz.

Yes it does have multiple hdmi ports, i currently use a ryzen 2200g cpu and yes the problem is only there with the nvidia drivers (all three of 'm).

Nouveau works fine.

When i set the nvidia driver and than go into screen settings and try to configure 4K @60hz @200% and hit apply i only get 1080p, it never switches to 4K.
Below 30hz @100% it does switch to 4K, but after reboot it will be back to 1080p

Thanks.

Certainly sounds like a software bug if 'modeset' is being used while the nvidia driver is installed.

summary: - 20.04beta: Cannot set 3840x2160
+ Nvidia driver installed but Xorg uses modeset on the Nvidia card.

Unless the nvidia kernel driver is in drm modesetting mode, and I can't see where that was turned on?...

Since you seem to have working DRM support on the card you wish to use, please try selecting "Ubuntu on Wayland" on the login screen.

How did you install the NVIDIA driver? While I can see the kernel modules being loaded, I don't see the NVIDIA libraries in the X log.

The first time i was able to install third party propietary software through the ubuntu installation process. (So nvidia was enabled after the ubuntu installation process if i remeber correctly.

Today I installed the nvidia driver through Updatemanagement console, because
currently the ubuntu installer crashes if i set it to install propietary software, this appearently already has been reported.

I have made a second thread (to get new report files to you, since i swapped my 2200G with a ryzen 5 2600. https://bugs.launchpad.net/ubuntu/+bug/1871422 ) - i will now try to login with wayland

Daniel van Vugt (vanvugt) wrote :

I forgot to mention; if the Nvidia driver is in a mode that will support Wayland we still hide the Wayland option. To unhide it you need to comment out the last line of:

  /usr/lib/udev/rules.d/61-gdm.rules

Although that will reintroduce bug 1705369 so you might need to also use one of the other workarounds mentioned in that bug.

I've been at it for just about one year now.
I can only hope you guys now have the information it takes to solve this.

I'm done swapping components, wracked a B450 motherboard and or Ryzen 2200g in the process.

I was thinking about that ryzen 7 3700X anyways, so not that big of a disaster.
But i hate the thought of maybe having to switch from 19.04 to 18.04 instead of 20.04.

Good luck, Paul

I just downloaded a daily build (12-04-2020)
And am very happy to report 4K 60 is working flawless on this version on the nvidia driver.

Yes I think this is some kind of failure to install the Nvidia driver correctly, such that the Xorg config was missing. It should work perfectly if installed from the official Ubuntu .deb files or via the GUI.

Unless the problem happens reliably I think this bug should expire.
