I bought a Dell XPS 13 9310 with the 11th generation i7 processor, Intel(R) Iris Xe Graphics, and preinstalled Ubuntu 20.04 (Kernel 5.6.0.1022-oem). After installing the suggested updates, I restarted the laptop and it has been restarted with flickering/tearing (horizontal lines) on the boot-up process and I cannot see and do anything. Then it goes into GNU GRUB options. I restored the system into the original configuration and have updated firmware to the last version (Ver. 1.1.1) and after installing the updates, I have still the issue. I have tried Ubuntu 18.04 and after installing updates the issue came back!!! See the flickering display photo

  • Does this answer your question? Graphical glitches using Ubuntu 18.04 on Dell XPS 13 2019 laptop – vanadium Nov 12 '20 at 10:22

    I have applied all the proposed solutions that I found on the net including:
    1. Modifying gedit~/.config/monitors.xml with lower refresh rate and even screen size.
    2. Adding 20-intel.conf into /etc/X11/xorg.conf.d, defining Intel Graphics device.
    3. Choosing "Ubuntu on Wayland" method.
    4. Applying sudo apt remove xserver-xorg-video-intel.

    Unfortunately, none of them worked!

  • I do not see the trick in the post of which I marked this as duplicate. There is a significant chance that that will resolve the issue. – vanadium Nov 12 '20 at 17:30
  • Thanks @vanadium, for your comment. Although I had tested this solution, I tried it again by 1) Updating the grub by using sudo vi /etc/default/grub, 2) replacing the line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash” with the following line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.enable_psr=0” 2) save the file and executing sudo update-grub, and finally 3) reboot.

    Unfortunately, the issue still exists. I will return the product to DELL or install MS Windows. I hope MS Windows works.

  • I retracted my duplicate flag: you indeed tested this correctly. MS Windows for sure will work. Since you purchased the laptop with Ubuntu, you will have support. I once returned a newly purchased Dell and they replaced the motherboard. So a specific issue with this machine is always possible. – vanadium Nov 13 '20 at 09:03

I'm fairly certain this issue is to do with the intel microcode - see https://bbs.archlinux.org/viewtopic.php?id=260710
