Ubuntu: Ubuntu 17.10 keeps locking up and freezing. Mouse and Keyboard input doesn't work as image on screen is frozen. Help!


I got an ultrabook 2 weeks ago and cleared out Windows 10 and installed Ubuntu 17.10. UI and system are great, but it keeps freezing on me, and I was forced to hold the power button to shut it down. I have tried the following fixes:


  1. sudo nano /etc/default/grub
  2. There is a line in that: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" (like this), replace with: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_idle.max_cstate=1"
  3. Save it (CTRL+O)
  4. sudo update-grub
  5. sudo reboot

I got this fix from another StackOverflow user: Ubuntu 15.10 and 16.04 keep freezing randomly

However it only worked for the first few days and after, it started the freezing craze all over again.

Then, I tried upgrading the kernel to the latest stable kernel:


But the problem still persists. It locks up every so often and I am forced to shut it down. I have a Dell Xps 13 9360, and the day I got it, I removed Windows and installed Ubuntu 17.10.

Is there certain fix for this?


I've had a similar issue to this where random freezing would occur with my mouse, this was after and upgrade from 16.04.

A lot of probing and research later, I found out it was linked to a problem with my display manager (gdm3) not being able to start Wayland. Using lightDM has fixed this issue for me.

Hope this helps

sudo dpkg-reconfigure lightdm


I've disabled Wayland because that's the only way I could PRIME Synch. work on my laptop with a designated card.

I experience random freezes as well. So probably because of wayland not loading, but don't know how to fix it. I doN't want to load it either...


It is likely drivers. In my case, I went to Dell.com, downloaded the BIN file that was the driver package for Linux and then ran it. They have specific ones for some other distros but the generic Linux one worked for me. So far no lockups.
