upstream actually suggested earlier to disable nouveau modeset by
default, so that it would have to be explicitly enabled if needed.. and
it usually isn't, since it's more or less just getting in the way when
trying to get the system installed with the NVIDIA driver

Title:
  Live USB freezes or cannot complete install when nouveau driver is
  loaded

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  When I boot the Disco 19.04 beta live USB, I can see a lot of errors
  related to nouveau in dmesg.

  Because of this, `lspci` freezes, so reporting an issue is impossible
  either with ubuntu-bug or sosreport (in both cases, the log gathering
  stops when trying to get the output from lspci).

  In addition, when nouveau is enabled:

  - the touchpad becomes unresponsive or behaves in a very weird way (slowing 
down, jumping), forcing me to use an external mouse or the little pointer in 
the middle of the keyboard.
  - the device cannot be powered off or restarted. It freezes and nothing can 
be done (I tried SysRq+REISUB to no avail)

  To avoid this issue, I need to launch the live USB with the following
  command line:

  $ cat /proc/cmdline
  BOOT_IMAGE=/casper/vmlinuz file=/cdrom/preseed/ubuntu.seed boot=casper quiet 
splash modprobe.blacklist=nouveau ---

  (that is, add `modprobe.blacklist=nouveau` to the command line in
  Grub)

  In the BIOS, I activated both GPUs (Intel and nvidia), which is the
  default settings.
