[Bug 1822044] [NEW] Laptop freezes after installation is finished when pressing "Restart Now"

[Pierre Equoy]

Public bug reported:

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
