Starting a snapshot doesn't start Gnome

Issues & Assistance GNOME
1

Because of the recent issues I had with Gnome not starting, I want to make sure the snapshots are working correctly. When I tried starting a snapshot I got saw a few errors from Tor I think and that was it. Gnome didn't start.

I was able to CTRL+ALT+F2 to go into another text only login prompt to log in.

Are the snapshots supposed to boot into the Gnome GUI?

Snapshots boot to a previous state of your system. By default your system is pre-configured to generate a new snapshot when certain events happen, for example updating your system or installing a new package.

The snapshots are taken regardless of the state your system is in at the time. In your case, it sounds like you have restored the version of Gnome that was broken for you (it was only thirteen hours ago you reported the issue fixed by an update: My Gnome+Wayland+Nvidia Destop will not start after update - #22 by josephmendoza). Any time you have a broken system, just be mindful you probably have some broken snapshots too.

If you would like to test the snapshotting feature, try installing or removing some packages and then roll back. Restoring a broken system after you have already fixed it is…not that useful. :smirk:

I think my snapshot should have been good actually. It didn't fail the same way it did when the Gnome bug occurred. I'm wondering if snapshots work for starting Gnome.

Anyway, as long as I get the system back to a state were I can use the terminal or SSH into then it should be fine.

Yes, booting into snapshots works just fine with Gnome.

You don’t need to make any special effort to get back to your working system if you booted a snapshot without restoring it–just reboot, and you’ll be right back where you started before booting the snapshot.
