Hello,
I am very new to linux so forgive me if my question sounds naive. So basically if something works for Ubuntu, will that work for say Fedora ?
I found a solution for one of my WiFi drivers for Ubuntu but I am running OpenSuSe, will it work ?
And what are premises that if something works on one distro it will work on all others. What is usually the case ?
Thanks

It depends. Some solutions are distro specific. Some are quite generic and can be applied ti most distros. It depends on a wide range of factors. Your wifi driver example might require some slight changes duecto different package managers, directory structures or names of some crucial config files. It depends. To get the best response, it is always good to ask specific questions.

In general Linux commands work the same, but distro's do have their own implementation of commands and/or the way a set of commands might be implemented.

SuSe for example is notorious when it comes to using yast(2) and doing the same from the command line (do not mix them, you'll end up with a non or partial working SuSe). One of the reasons I dislike this particular distro (I'm a CLI person and hardly use GUI's).

Another difference might be the package management that is used:
- deb -> Debian/Ubuntu (using apt / dpkg),
- rpm -> RedHat (using apt, yum),
- tgz -> Slackware (using slackpkg / swaret),
- etc, etc

The general concept might still work for a particular problem, but the way to get there might differ on other distro's.

EDIT: I'm too slow....

You could try posting your wifi problem as a new thread or going to

One thing about Linux is that there's always someone who's been there before you and knows the answer!
