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.
