Running #nixos #nixos25dot05 with #gnome or #kde_plasma desktop on #lenovo #thinkpad #x230 seems to require
services.xserver.displayManager.gdm.wayland = false;
This was what #chatgpt told me, and the fix it worked.
I used #flakes for the first time by following this nice video https://youtu.be/ACybVzRvDhs
#aircove #expressvpn #router #wifi #printing #brother #mfcl3770cdw on #nixos
0) Activate WiFi printing on printer (disables previous wired LAN connection, cannot have both)
1) enter new #ipaddress of the printer by adapting the #configurationdotnix (IP address shown on printer settings screen & web browser dashboard expressvpnrouter.com)
2) drag & drop printer into the so-called "group" "No VPN"
3) enjoy printing
Had set aside the whole afternoon 4 this but now can do the washing up instead.

Tried running #linux #tails operating system off a #bootable #usb .
#distro seems to work nicely. It entirely disappears on shutdown due to
being in RAM only. But then the OS needs all settings and configuration
set afresh on next restart.
What about if I run a #nixOS #container #vm #virtalmachine #virtualize
inside Tails then I could maybe use my #configurationdotnix after each
reboot to save manually reconfiguring after each reboot. What is the
best way of doing this? Tips welcome. Thanks!
@whydoesnothingwork Thanks 🙏 Really good clear useful video of how modules are needed / used in #nixos with the #configurationdotnix to set ( #port #ipaddress etc. ) parameters using #execstart and #systemd for an application / #package #clouddns providing a #service .
@wentasah My solution after same and / or similar problems:
use the following in my #configurationdotnix #nixconfiguration
configuration.nix
file:
services.printing.enable = true;
services.printing.drivers = [pkgs.brlaser];
with additionally the lines in the image below:
Complete configuration.nix is listed here

feedback welcome !!
After about 4 months running #nixos I had to fix the #printing problems. After many hours fiddling & trying various fixes, the only way I got my #Brother #LAN local #network #printer to work was to use the following in my #configurationdotnix #nixconfiguration
configuration.nix
file:
services.printing.enable = true;
services.printing.drivers = [pkgs.brlaser];
with additionally the lines in the image below:

link says configuration.nix is preserved on roll back.
