Dell XPS Broken After Linux Kernel Update

So … what happened?

I updated my XPS to the latest version of Ubuntu (22.04 LTS) which came with a lovely new kernel (woohoo!). The only problem … that kernel hosed my ability to boot the laptop (which is not so good). Kernel versions before 5.13.19 don’t seem to be affected at this point.

Reports

There are a few threads that describe the problem. If you have a big geek hat (or lots of time to waste) … it’s interesting reading:

What can I do?

Short of this actually being fixed by the kernel devs, the blogs suggest adding a line to your boot config. If you’ve never done this before, I’ll walk you through (it’s fairly easy):

  • Open a terminal (Ctrl+Alt+T on Ubuntu)
  • Run the following command to edit your grub config: sudo nano -KSw /etc/default/grub
  • Look for a line starting with “GRUB_CMDLINE_LINUX_DEFAULT”
    • Yours will most likely look like: GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash”
  • The only thing you need to do is add a space and the following after “splash” and before the ending double quote: i915.fastboot=0
    • The end result should be:
  • Once that’s done, hit CTRL+x to save.
  • Then you need to update your grub boot settings, so run: sudo update-grub
  • Finally, reboot and hope it all works!
