[Bug 1822026] Re: Live USB freezes or cannot complete install when nouveau driver is loaded

[Pierre Equoy]

This is the dmesg I get when booting with 19.04 beta and the default
parameters (i.e. nouveau activated) on this device.

** Description changed:

  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 
+ $ 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)
