I'm using Ubuntu 21.10. Recently, I the USB-C monitor (the HDMI is still working), it use to work with 5.13.0-35-generic but after another upgrade it doesn't work anymore.

Can anyone help?

More Information when I try to upgrade

How do I force them to Install?

  • Hello. I do not see anything that needs help. Sometimes a different kernel is needed for a certain config or piece of hardware. If that kernel works use it. – David Mar 26 '22 at 13:50
  • So I need to stay with a lower version of Linux Kernel? I don't understand the solution... – Yoram Mar 26 '22 at 18:58

    Does this answer your question? ["The following packages have been kept back:" Why and how do I solve it?](https://askubuntu.com/questions/601/the-following-packages-have-been-kept-back-why-and-how-do-i-solve-it) – Martin Thornton Apr 01 '22 at 14:32
  • Having the same issue on Ubuntu 22.04 LTS, with the 510 nvidia drivers. My HDMI monitor comes to life, while my USB-C monitor does not. The same monitor was connected 5 mins ago to Ubuntu 20.04 LTS, so i rule out monitor issues. – sastorsl May 09 '22 at 10:23

I have the same issue on my new HP Pavillion Gaming 15(Nvidia 3050 TI). I'm trying to solve it as well, but it looks that you need to guess which kernel is compatible with your graphic card.

"Easy" solution is to go to "Software Updates" on Ubuntu, go to settings on bottom left, press additional drivers and check the first option on top and press apply. In my case it's Nvidia 510 and then reboot.

Next problem you're gonna face is if your laptop goes to suspend mode it doesn't work normally unless you unplug external monitor and connect it back again.(At least in my case)

So in the end it was because the packages were held back

sudo apt install libnvidia-cfg1-510

installed all of the packages held back and sorted it!
