Ubuntu – Dell Inspiron 3593 shows display unclaimed for Intel Device 8a56 (rev 07)

delldriversgraphicsintel graphics

I installed Ubuntu 18.04.3 LTS on a Dell Inspiron 3593 (with Intel graphics card), but when I run lshw it shows the display is unclaimed. Unfortunately Dell discontinued their graphics update tool, because apparently Linux Kernel should already have all the drivers necessary. But as you can see apparently, that's not the case with me.

In Gnome, when I go to Settings, Details, Graphics, it says: llvmpipe (LLVM 8.0, 256 bits).

Here are some outputs:

Best Answer

This grahphics adapter is not supported by the 5.0 Linux kernel.

Install the 5.3 kernel by

sudo apt install linux-generic-hwe-18.04-edge

It should properly detect and support this adapter.
