hwdb.bin does not exist, please run udevadm hwdb --update

[rushmorem]

I'm running NixOS on the unstable channel. Hadn't updated my system in a couple of weeks or so. Yesterday I ran nixos-rebuild switch --upgrade. Upon restarting the machine GUI applications can't run, since X11 is failing to start.

The system partition is encrypted. Right before I get prompted for the passphrase I'm getting an error message saying hwdb.bin does not exist, please run udevadm hwdb --update. Once I enter my passphrase, the system proceeds to boot fine. I can login into xterm and all command line applications are running fine. Can't run any GUI apps though.

I tried running the said command by putting it in my configuration.nix file as boot.postBootCommands ie boot.postBootCommands = "udevadm hwdb --update"; to no avail.

In /var/log/x-0.log and /var/log/X.0.log I'm seeing the following error message... (EE) systemd-logind: failed to get session: PID 2804 does not belong to any known session.

I can confirm this hwdb.bin does not [...] message. Your X11 problems are probably due to #4923

[rushmorem]

That's what I thought as well but @vcunat's X11 server is still running fine according to that issue.

The message is unrelated to X11 problems - I corrected the title

@iElectric thanks.

Ignore the hwdb message, it's always been there, just not verbose.

X11 problem is related to #5266

• hwdb: I read on some Arch forum that the hwdb message should be ignored and will disappear in some following systemd release.
• systemd-logind: systemd-logind problem? #4923

I believe the real problem is that our ati_unfree doesn't work ATM (#5266). If you find the problem looks different, probably open a fresh issue.

Fixed, nice :-)
