Crash when unlocking screen if using Nouveau driver

[Islam]

Randomly but frequently when trying to unlock screen, it either becomes very slow (like when typing the password, characters are reflected very slowly) or it totally freeze and crash.
Also switching TTY's doesn't work and have to hard reset.

This was happening for me before while using Nvidia's driver but it has been working fine, now when I switched to the Nouveau driver, it constantly happens.

Another update, also it happens with Nviida driver but when PRIME profile is set to on-demand.
But performance mode is fine.

Thank you for taking the time to report this bug and helping to make Ubuntu better. It sounds like some part of the system has crashed. To help us find the cause of the crash please follow these steps:

1. Look in /var/crash for crash files and if found run:
    ubuntu-bug YOURFILE.crash
Then tell us the ID of the newly-created bug.

2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine. Do you find any links to recent problems on that page? If so then please send the links to us.

3. If step 2 also failed then apply the workaround from bug 994921, reboot, reproduce the crash, and retry step 1.

Please take care to avoid attaching .crash files to bugs as we are unable to process them as file attachments. It would also be a security risk for yourself.

gdm3 is not involved in screen locking so this is likely to be a crash in either Xorg or gnome-shell.

Please follow the instructions in comment #3.
