Last Tuesday I noticed that some electron apps generated crackling audio, so I made adjustments to the sound settings and did a rebuild with those settings. I only logged on one other time after that, at which point, I decided it was time to do a nixos-rebuild switch --upgrade
like I do on occasions. No, I don’t have the habit of backing up configurations, but I will once I resolve this.
Anyway, we had an abrupt situation in which we had to rehome a dog and we were busy with that until last night, when things finally calmed down and I was able to use my computer again.
I’ve now found that everything is much, much slower on NixOS than it was last week. The single most obvious symptom right now is the Application Launcher. I click on it and it takes up to 4 seconds to show up. I also noticed that the entire “Help” category of it is empty, along with “Favorites”.
Another noteworthy thing is that chrome based browsers are affected. Firefox seems unaffected. FF is my default, so it’s fine, but the Chrome detail may help diagnose.
Created a new user and logged on as that. No better.
I’ve since tried reverting my audio settings, along with all sorts of other reversions. Nothing seems to work.
The one thing I can do is load up the last generation from last Tuesday. Everything feels great in that generation. But I’m stuck and can’t add packages or anything. As soon as I rebuild, it churns to a halt again.
I’m suspecting the hardware configuration was changed during the --upgrade, but I’m too new to know for sure.
Here’s the current configuration.nix
And here’s a log from a fresh boot.
I’m really tempted to just back up configs and files and reinstall, but I’m a bit sick of solving everything in Linux with that. I’d like to learn to fix this stuff.
Any help is appreciated. Thanks.
