[nvidia] After updating to 18.04 only Wayland works. Cannot get Xorg to work on Gnome

[jim ruxton]

I recently updated to Ubuntu 18.04. After updating I can only log into Gnome if I select Gnome or Ubuntu with Wayland at my login screen. Nothing I can do will allow me tuse Xorg. I tried reinstalling Xorg and reinstalling my video driver (nvidia-390) . If I select Ubuntu with Xorg at login I get a purple screen and frozen mouse. If I set etting |WaylandEnable=false| in |/etc/gdm/custom.conf| I cannot get to the login screen. The system freezes.

It sounds like you might have two different bugs, if the purple screen is bug 1766137.

Please:

1. Run this command to attach more information: apport-collect 1771661

2. Run 'lspci -k' and attach its output here.

3. Copy /proc/cmdline and attach it here.

Thanks. It looks like you have a hybrid system with both Nvidia/Intel GPUs.

In case the freezes are caused by something crashing, please also:

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

2. Check for older crashes send from your system by looking at https://errors.ubuntu.com/user/ID where ID is the contents of /var/lib/whoopsie/whoopsie-id. If you find any links to crashes that you think are relevant then please share them here.

3. Attach output from 'journalctl -b' from right after a failure has occurred.

If I run this with a file "_usr_bin_gnome-shell.1000.crash" a crash
report is generated which I sent. I didn't get an ID however.

I only see the crash from above which was sent.

A file is attached with the results of 'journalctl -b' . To generate
this I set login to login using Xorg. After logging in the machine
crashed with a frozen mouse and a purple screen. I did a reset using
SysReq R E I S U B . When getting to login screen I reset login to use
Wayland. I logged in and ran 'journalctl -b' in a terminal .
