The Ubuntu Forums have grown tremendously over the years. While we regret that we are discontinuing our Other OS Talk category, this gives us an opportunity to help other Linux distributions grow by directing traffic to the websites of these distributions.
Here is a list of the official websites for the operating systems that used to have individual forums here. We hope you are able to find further assistance from there.
And finally, if you haven't yet found what you are looking for, we suggest you look for information on the DistroWatch website
or you might try the multi-distribution LinuxQuestions forum
