Ubuntu, GeForce GTX 1660Ti, problem with connection to external monitor through DP, HDMI

Graphics / Linux Linux
1

Hello,

I have an HP OMEN Ryzen 7 4800 with a GeForce GTX 1660Ti running a dual boot with Windows 10 and Linux - Ubuntu 20.04.2 LTS with 5.14.0-1020-oem kernel.

I started the following thread some time ago:

My problem was solved back then, but one day out of the blue, without doing anything that could change the “working” configuration (to my knowledge), upon booting my system up my laptop’s screen looked like static TV black and white noise.

After searching the issue online I found that kernel 5.13 was responsible for this bug.

After switching to kernel 5.11 or 5.14 the main screen was working again.

The problem is that I could not make my external monitor work anymore.

It worked with kernel 5.13(only the external monitor)until I switched my nvidia prime options to “Power saving mode (Intel)” trying to solve the problem.

I could not make anything work so far, even though I tried to follow each step of the solution of my previous thread.

Kernel: 5.14.0-1020-oem

I would appreciate any help.

Thanks in advance.

Please try reinstalling the kernel headers
sudo apt install linux-headers-$(uname -r)

sudo apt install linux-headers-$(uname -r) returns:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
linux-headers-5.14.0-1020-oem is already the newest version (5.14.0-1020.22).
linux-headers-5.14.0-1020-oem set to manually installed.
The following package was automatically installed and is no longer required:
  python3-crcmod
Use 'sudo apt autoremove' to remove it.
0 upgraded, 0 newly installed, 0 to remove and 16 not upgraded.

The command for re-installing would be: sudo apt reinstall …
But yeah, you already have the headers installed.
So you would need to dkms install the driver (not sure up to which kernel the 460 driver has support for) for your current kernel. It is installed for 5.13.0-27 - but that one is buggy, so try it for the 5.14 one.
And why not go with the current production release?
sudo apt install nvidia-driver-470

@Mart Actually the 460 driver for 5.13.0-27 was working just fine. The bug was with the laptop’s main screen which was using the AMD card. The external monitor was using NVIDIA connected through the DP.

But I tried to install the 470 driver with sudo apt install nvidia-driver-470 but something is wrong here too:

Fix that first hand, otherwise apt won’t do anything.
You could try: sudo apt --fix-broken install

7

I tried sudo apt --fix-broken install and then again sudo apt install nvidia-driver-470 but it did not work once again.

8

Without terminal output, it’s just a guessing game for those willing to help you. So please provide helpful info.

You are right I thought it was the exact same output like before that’s why I didn’t provided the terminal output.
It is slightly different though. Here it is:

You have to correct your broken package manager situation first!

Done!(The nvidia 470 drivers part.External monitor still don’t work)

For anybody with similar issues, I installed aptitude with sudo apt-get install aptitude and then installed the drivers with it sudo aptitude install nvidia-driver-470

I don’t know if it helps but the output of modinfo nvidia is:

The output of nvidia-smi is still:

Hope it helps, thanks in advance,

Please create a new bug report.

Here it is:
nvidia-bug-report.log.gz (140.4 KB)

nvidiafb is loading, but it should be blacklisted.

Please look for nvidia blacklist files:

grep -r nvidia /etc/modprobe.d /lib/modprobe.d

if you do find a file with the entry: blacklist nvidia, that entry should be removed.
if you do NOT find a file with the entry blacklist nvidiafb, you should create one (ie /etc/modprobe.de/blacklist-nvidiafb.conf) with exactly that content.

If any of this applies, then run sudo update-initramfs -u and reboot.

Hey @Mart Everything seems to be working properly now!

Thank you very much for your help and your time!
