Hello!
I had an OOM today (thanks websites, which consume 1.5 G for three text fields), and GDM session crashed. But it also crashed so badly, that there’s no user showed up in gdm, here’s journalctl.
I logged in via lightdm. But I like gdm. Any idea how I can somehow force Nix GC erase everythning about gdm and set up it back?
(I’m quite new to NixOS, but am already a big fan of it)
If anything in the nix store is actually wrong, you can find it with nix-store --verify --check-contents. If that doesn’t report anything, you have no need to try to force nix to do anything. Any problem you have is related to your state outside the nix store.
No errors there. This means, I can be 100% sure that gdm is in the same state as if it was on a new machine?
You can be 100% sure gdm’s nix store paths are, yes. gdm presumably also has state somewhere though, probably under /var, which may be quite borked.
