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.

I've got one progam that I need for work that I cannot get to run on Linux. I've tried WINE on both Ubuntu and Zorin (and winlator for android). I have the installer exe file and try to launch with WINE but then nothing happens. Is that a program problem, WINE limitation, or something else? Is there a different program I should try to launch it?

I got one!

What constrains access to an rpc socket in the file system? Is it just the permissions of the socket or is there more to the whole process?

E: I originally wrote port instead of socket because it was early lol.

Howdy. I have a "homeserver" that I'd like to actually start using. What's currently keeping me from it are... Permissions.
I have TrueNas Scale running on top of Proxmox, and I can't for the life of me not access NFS Shares from other VMs (specifically a Debian VM that I use as Docker Host) that I host in Proxmox. Plox hlp.

I want to upgrade (Mint 21.3 => 22). Last upgrade took hours and the result was so bad I had to reinstall Mint from scratch. Do you guys use the upgrade tool, or do you have good advice on how to approach this?

I have a server that has multiple services running under multiple users that each store data. I want to be able to bundle all this data up and send it to another server for backups.

At a high level, how do I manage permissions for this? Currently I run the backup as root, then chown it to a special backups user which can log in through ssh. But this all feels clunky to me.

There are many ways to do this, but the next up from users is using groups!

For each file or data directory, create a group that owns it. This group should have the service's user as member. Then create a user for running the backups, and add it to all these groups.

The benefit of this is you don't have to use root, and you have an association of directory to group that you can always change. You can for example grant a user access to a data directory by just adding it to its group.

Might want to take a look at a dedicated backup tool like Borg. It will keep all the proper permissions and file attributes in the backup.

Is it that much better to have a Desktoo Environment, on my desktop computer? I'm still halving it with Windows trying to get my games to run on arch lol

[–] potentiallynotfelix@lemdro.id 3 points 2 months ago (3 children)

Can you elaborate on the issue you are having? Having a desktop environment is usually necessary to run games.

[–] Sanctus@lemmy.world 2 points 2 months ago (1 children)

I tried running i3, using the arch wiki for the nvidia package. It suggested just the 'nvidia' package for a 2080 TI. Launched steam with proton (forget the newest version at the time it was like last month). Nothing would happen when launching any game. Probably doing a lot wrong or something, sorry if this isn't enough info. I did no logging.

First off, I'd recommend you use the nvidia-dkms package, because that can make upgrading kernels easier. Second, let me explain the hierarchy of GUIs on Linux. At the base level, you have the display server. In your case, you are using the X11 display server. The display server is at a very low level, and only handles the rendering of content. The three prominent display servers are X11 and Wayland. The second tier is the window manager. It's pretty much essential, and it lets you move around windows, stack them, etc. You're using i3. The third tier is desktop environment. The desktop environment is completely optional, and it controls things like taskbars, start menus, and system trays. DEs are not needed for computer use, but they can make things like customization easier.

In your case, I don't believe your issue is with your window manager or display server, I believe it is with Steam or Proton. What game are you trying to play? Some games aren't able to be compatible with Proton, unfortunately.

Edit: A few corrections that I just thought of. First off, the display server doesn't "just" handle rendering things. It handles input, and communicates to Linux, which will tell the hardware what to render. Second, I didn't explicitly mention this, but I thought that I should, a desktop environment still relies on a window manager for handling windows, it just adds functionality. Also note I wrote this reply partially in response to another commend, so sorry if I yapped a bit too much.
