Newest mutter patch prevents it from starting

[JouHouFin]

I'll try to provide as much information as I can, but as this is the first issue I've ever submitted, try to bear with me.

I ran sudo dnf --refresh upgrade today and it installed the newest mutter patch from @updates (I have had the gnome-with-patches enabled for a long time). After restarting the machine, only the mouse cursor shows up, the rest of the screen stays black. The issue goes away when I disable the gnome-with-patches repo and downgrade mutter and gnome-shell via cli.

Steps to reproduce:

$ sudo dnf copr enable pp3345/gnome-with-patches
$ sudo dnf upgrade
$ reboot

Steps to remedy the issue:

$ sudo dnf copr disable pp3345/gnome-with-patches
$ sudo dnf downgrade gnome-shell mutter
$ reboot

I'll try to clarify my first post, which probably wasn't very clear. Just tested this with my desktop computer, which also has Fedora 30 and gnome-with-patches enabled and the same problem occurred.

Mutter and gnome-shell package states when everything is working (copr gnome-with-patches disabled at this point):

Installed Packages
Name         : mutter
Version      : 3.32.2
Release      : 4.fc30
Architecture : x86_64
Size         : 15 M
Source       : mutter-3.32.2-4.fc30.src.rpm
Repository   : @System
From repo    : updates

Size         : 8.4 M
Source       : gnome-shell-3.32.2-2.fc30.src.rpm
Repository   : @System
From repo    : updates

Now, I run these commands:

$ sudo dnf copr enable pp3345/gnome-with-patches
$ sudo dnf upgrade

After that, mutter and gnome-shell packages are as follows:

Installed Packages
Name         : mutter
Version      : 3.32.2
Release      : 4.fc30
Architecture : x86_64

Repository   : @System
From repo    : copr:copr.fedorainfracloud.org:pp3345:gnome-with-patches

And after reboot, all I see is mouse cursor on black.

Dear JouHouFin, In my desire of making GNOME faster, I followed the commands of the Copr repository. Unfortunately things didn't turn out as expected. I reproduced your problem and the worst thing is that I don't know how to remedy the issue as you say. Because Ctrl+Alt+F2, or any 'Fx' displays texts but doesn't allow me to log in with my account writing the username and password.

I would like figure out how can even execute the rollback commands since for the moment I haven't come up with a console where I can type the commands.

Any ideas? Thanks beforehand, Best regards,

[JouHouFin]

@dbgithub, So any one of Ctrl+Alt+F3-F6 doesn't bring up the login console?

[dbgithub]

Indeed. When I press any of those, I see some logs printing out such as: acpi PNP 0501:00 still not present, but the latter doesn't seem to be the problem, is just an example of the output I see. When I go back to Ctrl+Alt+F1, all I see is the Fedora logo at the bottom (centered) and the mouse pointer. I am feeling a bit panic right now Thanks once again,

No worries! Thanks a lot for your report, you did great :-)

Of course this had to happen while I was on vacation -- just returned home, I am very sorry for the delay.

I've just pushed an updated build to Copr that fixes this issue. You may now safely enable the Copy repository again.

@dbgithub Press Ctrl+Alt+F3 as @JouHouFin said, then wait a moment. Sooner or later you should see a login prompt where you can log onto the command line by using your user name and password. Then run dnf update --refresh and reboot. Everything should be working again.

Sorry again for the inconveniences. I'll close this issue now as I believe it's fixed. Don't hesitate to reopen or ask if you still encounter any problems.
