Ubuntu 18.04 install (also seen on 16) is unable to detect integrated Intel graphics card (Intel Iris Plus). Using a Dell XPS 13 2-in-1 7390 the machine is unable to detect attached monitors, change resolutions, or adjust brightness.

There is a dual boot Windows 10 partition, which can access the integrated graphics card without issue and connects to attached monitors on boot. However, after deleting the W10 partition the behaviour is unchanged.

I have tried purging nux-tools to remove a leftover file that interfered with gnome as detailed in this bug.

Further, this fix for intel integrated graphics cards also produced no results.

  • Please [edit] your question and add output of lspci -k | grep -EA3 'VGA|3D|Display' terminal command. – Pilot6 Nov 22 '19 at 16:48

I suggest to upgrade the kernel to an officially supported HWE kernel.

You can do it by running

sudo apt install linux-generic-hwe-18.04

Reboot to apply.

I have the same problem with the same graphics card in a Dell Inspiron 5593, I solved the problem of the brightness updating the kernel to the latest version.

You can easily update the Kernel with ukuu, it's totally safe, if you have problems with a newest Kernel, you just boot with an old Kernel and change the Kernel version again with ukuu.

If you find a solution to the llvmpipe problem, please write about it, I'm still looking for something.
