I got a new laptop a few days ago, a Dell Inspiron 15 3000. In my country, you can't get the developer edition (with Ubuntu preinstalled), so I settled for the one with Windows 10. I swiftly installed Ubuntu, which worked fantastically, except that I couldn't change the brightness, or the color profile, or turn Night Light on.

After some searching I discovered that my graphics card (integrated) was not being used, and the CPU was rendering graphics. I then tried changing the GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" line in /etc/default/grub to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.alpha_support=1". This fixed the problem of llvmpipe being the graphics, and switched it to Intel® Iris(R) Plus Graphics (Ice Lake 8x8 GT2).

After this, I could change the brightness, but I still couldn't change the color profile or activate Night Light. There was also a thin white line that would irregularly flash at the top of my screen (couldn't be screenshotted).

My only idea is that it might be something to do with the newness of my graphics (10th gen)? I have almost no experience with firmware, so help would be greatly appreciated.

If it helps, here's the output of xrandr:

  • Older thread, not sure if it still applies. Start at last post & work forward. ubuntuforums.org/showthread.php?t=2195650 – oldfred Dec 26 '19 at 23:36
  • Hmm. That seems to be just to do with brightness, I have fixed the brightness issue, now it's color profile that still don't work. Also, I thought Ubuntu didn't use xorg.conf anymore? – arctic_hen7 Dec 27 '19 at 0:32

Okay. I had a think about Intel's 10th Gen systems, and realised they were released in 2019. Ubuntu 18.04 and earlier just don't support them. Ubuntu 19.10 supports them perfectly. If anybody else has this problem, upgrade to 19.10, it fixes everything. I did a clean reinstall because I hadn't done anything on the system yet, so I'm not sure if an upgrade from within 18.04 will work. Thank you to all those who assisted me!
