[Ubuntu-x-swat] [Bug 1870637] Re: 20.04beta: Cannot set 3840x2160
Thanks. Certainly sounds like a software bug if 'modeset' is being used while the nvidia driver is installed. ** Summary changed: - 20.04beta: Cannot set 3840x2160 + Nvidia driver installed but Xorg uses modeset on the Nvidia card. ** Changed in: nvidia-graphics-drivers-435 (Ubuntu) Status: Incomplete => New ** Changed in: xorg-server (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1870637 Title: Nvidia+modeset: Can't set 4K@60Hz: HDMI max TMDS frequency 30KHz To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-435/+bug/1870637/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

> 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. 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 -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1870637 Title: Nvidia driver installed but Xorg uses modeset on the Nvidia card.

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. ** Changed in: nvidia-graphics-drivers-435 (Ubuntu) Status: New => Incomplete ** Changed in: xorg-server (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1870637 Title: 20.04beta: Cannot set 3840x2160 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-435/+bug/1870637/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 1870637] Re: 20.04beta: Cannot set 3840x2160
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?

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. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1870637 Title: 20.04beta: Cannot set 3840x2160 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1870637/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

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 -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1870637 Title: 20.04beta: Cannot set 3840x2160 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1870637/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 1870637] Re: 20.04beta: Cannot set 3840x2160
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?): [18.036] (--) modeset(0): HDMI max TMDS frequency 30KHz [18.036] (II) modeset(0): Not using default mode "3840x2160" (bad mode clock/interlace/doublescan) [18.036] (II) modeset(0): Not using default mode "2560x1440" (bad mode clock/interlace/doublescan) 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. ** Changed in: xorg-server (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1870637 Title: 20.04beta: Cannot set 3840x2160 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1870637/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
