Installed on Linux Mint. Some minor UI problems here and there. But that's nothing compared to how bad autocomplete is. At least for PHP development it's unusable at all. Because of that even had no intention to check further. But for those who wonder - yes, it works on Linux.
Did you find or compose any kind of build instructions?
There are build instruction for Linux in README. https://github.com/atom/atom \nPlus I had to fix libudev problem with this https://github.com/atom/atom/issues/1814#issuecomment-423253... Other than that it had no problems to build or launch.
