New Latutude 5520 - display and HDMI issue

[kobusventer]

Hi Guys
I have received a new laptop from the Company i work for, and installed Mint 20.3 on it, with kernel 5.4.0-94.
However, I had problems from scratch, using the HDMI port, as it does not seem to initialize. I then upgraded the kernel to 5.4.0-96, which is currently active, however, the second display still does not initialize.

I might be wrong, but it seems to me that the issue is not with the HDMI port, but rater with the display driver?
I also ran the following

I have received a new laptop from the Company i work for, and installed Mint 20.3 on it, with kernel 5.4.0-94.

The inxi data you posted indicates there is no graphics driver installed. The 5.4 kernel is too old to have the drivers for your 11th-gen Intel CPU.

Graphics: Device-1: Intel driver: N/A
Display: x11 server: X.Org 1.20.13 driver: fbdev
unloaded: modesetting,radeon,vesa resolution: 1366x768~76Hz
OpenGL: renderer: llvmpipe (LLVM 12.0.0 256 bits) v: 4.5 Mesa 21.0.3

However, I had problems from scratch, using the HDMI port, as it does not seem to initialize. I then upgraded the kernel to 5.4.0-96, which is currently active, however, the second display still does not initialize.

You need to upgrade to the 5.13 kernel which is available in Update Manager.

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.

I also updated the code:

Code: Select all

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to

Code: Select all

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash drm_kms_helper.edid_firmware=HDMI-A-1:edid/1920x1080.bin"

Please remove the kernel parameter you added as that will mess up the ability of the graphics to work properly once you get the correct graphics driver installed.
