It's best to play through the official Linux Client to avoid browser-related problems or to bypass limitations that the Java Plugin might have.
There are many Linux distributions, so what works on one distribution may not work on another, or even on another version of the same distribution.
Troubleshooting Linux Issues
Because of how Linux can be set up, on almost any hardware, with many distributions, which may not include drivers or auto updates, a wide variety of issues can occur.
Many Client errors are caused by package incompatibility, so if you're having issues, you should ensure that you have the latest (stable, non-beta) version of your distribution. We'd also recommend sticking with Ubuntu, as the client may not download / run properly on other variants.
Using other Linux packages
Other players have tweaked and packaged out Ubuntu Linux package into a form which installs on almost any Linux distribution:

- https://snapcraft.io/runescape
- https://aur.archlinux.org/packages/runescape-launcher
For those upgraded onto a Jagex Account, it is worth noting that Linux isn't officially supported with the Jagex Launcher. If you wish to continue playing on a Linux machine, you can check out the community projects listed on the Downloading the Jagex Launcher on Linux article for further information.
Please be aware all 3rd party modified clients are used at your own risk. We always recommend using the official game clients offered by Jagex.
