No GRUB and further issues after Ubuntu 18.04 install on Dell XPS 15 9560

  • 772

I have just done a clean install (wiping the disk to remove windows) of Ubuntu 18.04 on my Dell XPS 15 9560, after updating ubiquity to avoid a bug as described here. Unfortunately after the installer finished it freezed after me accepting the reboot (could be the cause for the GRUB problem?), so I had to restart it by holding the power button.

After reboot, GRUB does not show up as usual but instead Ubuntu boots directly, which is very odd.

Then, after the login screen, I just see the cursor on a plain background. Now this is probably an issues with the Nvidia drivers, which I would like to solve either

  • by adding nouveau.modeset=0 to boot parameters - can not do because GRUB does not show up
  • or by installing Nvidia drivers similar to here - can not do because the machine is not connected to Internet after installation.

Additionally, errors like soft lockup - CPU stuck or task ... blocked for more than 120 seconds keep popping up: soft lockup - CPU stuck task ... blocked for more than 120 seconds

Can anybody suggest a way how I could finally achieve a working Ubuntu installation?

    I was not able to solve the issue directly but I achieved a well running Ubuntu installation using a respun ISO, see JackHack96's GitHub. Useful tips for getting it to run well can be found in tomwwright's gist.

  2. Hold Shift for 3 seconds after turning the system on. The GRUB should appear. Then press E and type nomodeset before quiet splash and press Ctrl+X.
