From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

home-manager to install gui applications on non nix-os distros (kbin.social)

I'm trying to use home-manager to install software on tumbleweed so that if I ever move to a new machine, I'd be able to install all of my software again by just running home-manager switch. For my terminal applications like zellij, zoxide, eza etc they installed and work fine.

My problem is gui applications that I've tried to install. I tried to install alacritty and awesome as I already have configs for them and wanted to move them over to being managed by nix. For alacritty, I ran into a "failed to find suitable GL configuration" error where I found this link to a github issue but beyond this, not sure how to really fix this: https://github.com/NixOS/nixpkgs/issues/230660

For both packages, I saw that alacritty was installed in nix-profile/share/application and awesome was installed in nix-profile/bin. To make awesome appear in sddm, im assuming I would need to make a custom entry in /usr/share/xsessions with exec pointing to its nix-profile location but I'm not entirely sure how to get alacritty running correctly.

I'd appreciate any help on this. Thanks in advance

Edit:
Tried out making a custom entry in usr/share/xsession and pointed it at awesome in the nix-profile/share directory but no luck getting that to be picked up by sddm

Cheers. I think I can get that working for pulling up alacritty or wezterm with awesome or leftwm with keybinds ( just changing what's being executed when using keybinds).

Is there a way to get this running through the applications symlink? I know I could symlink the location from nix-profile to applications using
ln -s /home/$USER/.nix-profile/share/applications/* /home/$USER/.local/share/applications/
But, is there a way to run nixGL from the symlink without running the command through the terminal first?

Credit: Chris Titus Tech for his intro to the nix package manager. That's where I found the symlink command https://christitus.com/nix-package-manager/

Edit:
I use rofi as my app launcher where I could use drun to execute alacritty or wezterm using nixGL but would really appreciate if I could just select the app from the rofi menu to execute directly without specifying the extra config param each time

https://github.com/nix-community/home-manager/issues/3968 - this to monitor and poke, there are also a link for a sample wrapper that might or night not help you.
