My new laptop came with Intel Core i5-1035G4 processor. I have installed Ubuntu 18.04.3. It has only one resolution in the display menu and the brightness controls are missing. This is most probably due to the graphics drivers but I can't seem to find graphics drivers for Ubuntu.

Does anyone know how I can update the graphics drivers?

Edit:

lspci -k | grep -EA3 'VGA|3D|Display'

00:02.0 VGA compatible controller: Intel Corporation Device 8a5a (rev 07)
    Subsystem: Hewlett-Packard Company Device 86c9
    Kernel modules: i915

uname -a

Linux linux 5.0.0-23-generic #24~18.04.1-Ubuntu SMP Mon Jul 29 16:12:28 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

  • There are no installable drivers for Intel adapters. You could ask about brightness control. Some laptops need some tweaking. – Pilot6 Jan 13 '20 at 12:20
  • @Pilot6 How about display-resolution? Is there anyway to add more? I have a FHD screen but the resolution is 1024x768 (4:3). – zindarod Jan 13 '20 at 12:24
  • Please edit your question and add output of lspci -k | grep -EA3 'VGA|3D|Display' terminal command. – Pilot6 Jan 13 '20 at 12:26
  • And also output of uname -a – Pilot6 Jan 13 '20 at 12:27
  • @Pilot6 Added info as requested. – zindarod Jan 13 '20 at 12:38

It looks like this adapter is not supported by the 5.0.0-23 Linux kernel.

First update your system by

sudo apt update && sudo apt upgrade

reboot and test.

If this doesn't help, try the 5.3 kernel that can be installed by

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

reboot to apply.

  • Thank you so much. The new kernel fixed the brightness controls and replaced the 1024x768 (4:3) with 1920x1080 (16:9). I added my desired resolution manually with xrandr. But the output of lspci -k | grep -EA3 'VGA|3D|Display' is still the same. clinfo returns number of platforms 0. – zindarod Jan 13 '20 at 15:08
  • The output is not the same, now you have the correct driver in use. – Pilot6 Jan 13 '20 at 15:33
  • This is the output. – zindarod Jan 13 '20 at 15:37
  • So that's what I wrote. See the difference? – Pilot6 Jan 13 '20 at 15:47
  • The kernel driver line. – zindarod Jan 13 '20 at 15:49
