Troubleshooting

The launcher

You see	What to do
Download failed! Please check your internet connection and retry.	Check your internet connection and press Retry Download.
Nothing happens when you open Minecraft	Run `mc-installer` in a terminal and look at what it prints. Include that if you open an issue.
The launcher asks you to sign in every time	Open an issue with your Linux version (`lsb_release -a`).
Clicking in the launcher does nothing, or menus close by themselves	Try the Tab and Enter keys to get through, and open an issue saying which graphics card you have.

You see	What to do
The game window is see-through or black	Update the snap (`sudo snap refresh mc-installer`); versions before 14.3 had this problem on some NVIDIA PCs.
On a laptop with two graphics cards, the game is slow	Right-click Minecraft in the app grid and choose Launch using Discrete Graphics Card.
Couldn't load Narrator library in the logs	Harmless: only the narrator (text-to-speech) is affected.
The game closes straight after starting	Look at the last lines of `logs/latest.log` (see Files and Backups). With mods, it usually names the mod at fault.

You see	What to do
Incompatible version or Outdated client/server	Play the server's Minecraft version: see Playing on a Server.
Connection Lost mentioning registry entries, or a mod	The server needs a mod you don't have: see Mods, Joining a server that has mods.
Can't connect to server	Check the address, and that the server is running. At home, both computers must be on the same network.

See the table at the end of Mods.
