Hi! Thanks a lot for the reply and sorry for the delay... I probably should activate email notifications + xmas happened. However, the issue is still there and my eyes would really appreciate having an external monitor connected to my Dell.
Your hardware is too new to be using the 5.4 kernel. It does not have the necessary graphics drivers (as you have noticed).
System:
Kernel:
5.4.0-109-generic x86_64 bits: 64 compiler: gcc v: 9.4.0
Desktop: Cinnamon 5.0.7 wm: muffin 5.0.2 dm: LightDM 1.30.0
Distro: Linux Mint 20.2 Uma base: Ubuntu 20.04 focal
Instructions for upgrading to the 5.13 kernel:
- Open Update Manager.
- Select View > Linux Kernels and click Continue.
- Make sure 5.13 is selected on the left panel and then click the top-most option on the right panel. An "Install" button will appear.
- Install the kernel and then reboot for it to become active.
That should install the proper drivers. Let us know if that clears the issue with the external monitor.
I want to caution you that your Mint installation is rather full so you will need to make sure you are diligent about "housekeeping" with regards to unnecessary software.
Code: Select all
Partition:
ID-1: / size: 27.38 GiB used: 19.42 GiB (70.9%) fs: ext4
dev: /dev/nvme0n1p5
ID-2: /home size: 351.93 GiB used: 293.49 GiB (83.4%) fs: ext4
dev: /dev/nvme0n1p6
ID-3: swap-1 size: 8.57 GiB used: 0 KiB (0.0%) fs: swap
dev: /dev/nvme0n1p7
Once you have two 5.13 kernels installed (one for use and one for a back-up in case you need to revert to it), you can remove all installed 5.4 kernels. Until you remove all of them, you will continue to get update notifications for them. Considering they do not have the necessary graphics drivers for your system, I suggest just installing a second (older) 5.13 kernel and removing all the 5.4 versions.
You can remove 5.4 kernels individually using a process similar to what I listed for installing the 5.13 kernel. Just select 5.4 on the left panel and then click a kernel with "Installed" in the middle column to have the "Remove" button appear.
