Title:
  Laptop freezes after installation is finished when pressing "Restart
  Now"

Status in ubiquity package in Ubuntu:
  Confirmed

Bug description:
  As stated in lp:1822026, the Dell Precision 7530 I'm using is using
  nouveau graphics drivers by default when starting a live session, and
  this driver is prone to errors.

  One of the most annoying for a new user is the following:

  1. Boot into 19.04 live session
  2. Launch "Install Ubuntu 19.04" and go through the installation steps
  3. Once the install is done, the "Installation Complete" dialog is shown with two options: [Continue Testing][Restart Now]
  4. Press [Restart Now]

  Expected behaviour:

  4. The device restarts and boots into freshly installed Ubuntu 19.04.

  Actual behaviour:

  4. The device freezes and even the keyboard combination SysRq+REISUB
  doesn't do anything. User has to force shutdown the device by pressing
  Power button for a few seconds, remember to remove the USB drive, then
  manually start the device.

  All the hardware-related information is available in the sosreport
  attachment in lp:1822026:
