Dealing with that Powershell error

https://stackoverflow.com/questions/42950853/docker-the-computer-windows10-on-se-could-not-be-resolved/45099242#45099242

Unable to execute Start: Unable to create: The running command stopped because the preference variable "ErrorActionPreference" or common parameter is set to Stop:

Now restart docker and after restart completion execute following commands in dos admin mode to setup the network card manually

netsh interface ipv4 set address name="vEthernet (DockerNAT)" static 10.0.75.1 255.255.255.0

You have to run this command everytime whenever you are doing system restart and docker completes start process (due to any reason). TIP : create a batch file of this command and save somewhere handy.

Note: The ps hack would get undone by any docker update. so be aware...

Hack

Open C:\Program Files\Docker\Docker\resources\mobylinux.ps1 with any editor in admin mode. Find following code (around line 164)

$networkAdapter | Remove-NetIPAddress -Confirm:$false -ea SilentlyContinue

$networkAdapter | Set-NetIPInterface -Dhcp Disabled -ea SilentlyContinue

$networkAdapter | New-NetIPAddress -AddressFamily IPv4 -IPAddress $switchAddress -PrefixLength ($SwitchSubnetMaskSize) -ea Stop | Out-Null

Add a return after line 165 in a new line like below and save the file.

$networkAdapter | Remove-NetIPAddress -Confirm:$false -ea SilentlyContinue

$networkAdapter | Set-NetIPInterface -Dhcp Disabled -ea SilentlyContinue

return

$networkAdapter | New-NetIPAddress -AddressFamily IPv4 -IPAddress $switchAddress -PrefixLength ($SwitchSubnetMaskSize) -ea Stop | Out-Null

Now restart docker and after restart completion execute following commands in dos admin mode to setup the network card manually

netsh interface ipv4 set address name="vEthernet (DockerNAT)" static 10.0.75.1 255.255.255.0

You have to run this command everytime whenever you are doing system restart and docker completes start process (due to any reason). TIP : create a batch file of this command and save somewhere handy.

Powershell

ssh-keygen

vcgencmd get_camera

Linux

Alacritty

Fix config errors

[WARN] see log at /tmp/Alacritty-2994.log ($ALACRITTY_LOG): Unused config key: colors.footer_bar

alacritty migrate

Then comment out obsolete properties until errors stop showing from ~/.config/alacritty/alacritty.toml. Repeat for dynamic_padding and window.opacity.

Garuda

If Add/Remove Software doesn't show up as a menu option

pacman -Syu pamac-aur

Sway

cheatsheet:

https://wiki.garudalinux.org/en/sway-cheatsheet

Enabling numlock on boot

https://wiki.archlinux.org/title/Sway#Initially_enable_CapsLock/NumLock

edit .config/sway/config.d/input

append input type:keyboard xkb_numlock enabled

Setting up monitors

Use wdisplays ("Displays") to arrange monitors.

Then swaymst -t get_outputs to get current config.

Then edit ~/.config/sway/config.d/output.

my config:

output DP-1 mode 2560x1440@154Hz position 1440 0
output HDMI-A-1 resolution 1440x900 position 0 540

Running X apps as root

Make sure the output of pgrep -af polkit indicates that you have a polkit daemon & agent running:

883 /usr/lib/polkit-1/polkitd --no-debug
2122 /usr/lib/polkit-gnome/polkit-gnome-authentication-agent-1

Then try:

xhost si:localuser:root

Without this, you'll see errors like:

Authorization required, but no authorization protocol specified

qt.qpa.xcb: could not connect to display :0
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb.

fish: Job 1, 'sudo garuda-boot-options' terminated by signal SIGABRT (Abort)

If that doesn't do the trick, e.g, pacmac-manager is silently not able to install from AUR, then create ~/.config/environment.d/.conf with contents:

DISPLAY=:0
WAYLAND_DISPLAY=wayland-0

and reboot. See keybase/client#19614 for details.

Docker (and specifically containerd) can also cause polkit issues. Try disabling docker, docker.socket, and containerd. See https://bbs.archlinux.org/viewtopic.php?id=284158&p=2 for details.
