I see.

Here is what I would do:

#1. Have an ssh connection ready. Right after doing your `modprobe
nouveau`, run `dmesg` from the ssh connection and copy/paste.

#2. All logs are stored in /var/log/syslog. Then they are archived in
gz form. So you should be able to do something like `zgrep nouveau
/var/log/syslog*.gz`. It may be more difficult to search through this,
so I would suggest #1 first if you can.

The changes in `/var/log/syslog` after `modprobe nouveau` (are the same
as in `dmesg`):
