stable@2016-06-11 to unstable@2016-07-20

Accidentally updated from stable channel to unstable: 0546a4a -> 125ffff

new problems i managed to solve

Xorg does not accept connections from system users

not sure how long it didn't work but xhost fixes it.

services.xserver.displayManager.sessionCommands = ''
  ${pkgs.xorg.xhost}/bin/xhost +local:
'';

msmtp stopped working

trying to start up msmtp results in:

Just to finish sending my mail I installed old msmtp into user env:

find /nix/store -name msmtpd -type f
nix-env -i /nix/store/pzfam2i2kpfdncz8yzyn5bkxq7fmin8z-msmtp-1.6.4/bin/msmtp

GPG agent stopped working

Seems like in gpg 2.1 write-env-file became obsolete:

gpg-agent[14303]: WARNING: "--write-env-file" is an obsolete option - it has no effect`

Touchpad enabled on X220 but in retard mode

I use the trackpoint instead, before it was disabled by default.

Devpi stopped building

Tests are activated by default for python packages. For some reason my devpi package contains failing tests, too lazy to investigate.

broken stuff i will fix by waiting for a new release

  • Xorg takes 10 seconds to boot - I do not boot too often, will have this solved via enterprise-waiting. UPDATE: i think this is related to vboxnet0 to time out after 1min 30sec
  • Screen flickers when root user logs in - Redshift is now a systemd user service which results in redshift starting up at connect. Will not do anything.
  • systemd --user fails - see https://github.com/NixOS/nixpkgs/issues/15653
  • cannot print anymore on Samsung SCX-3200 Printer - overwriting cups and cups_filters results in mass rebuild for my unstable revision

solved with update

Some things actually get solved with the new rev:

  • chromium does not use up all 4 CPUs when showing videos
  • nixos module security.acme provides preliminarySelfsigned for automated ssl certificate creation
