When trying to launch Minecraft, you may notice that the key-input is not working properly, leading to a character that cannot move but only interact with blocks around him.
This issue is related to ibus, which is used as a character input client for Chinese, Japanese and Korean among others.
In order to solve that, you need to kill ibus during the time Minecraft is launched.
I think you already downloaded the game client minecraft.jar from dedicated website. Then save it in a folder called $FOLDER. Here $FOLDER=$HOME/bin/java.
Then use this script to launch minecraft.
#!/bin/bash
#Minecraft launcher
#This is here to solve issues with key input in linux systems
#Kill the ibus daemon
killall ibus-daemon
#Launch minecraft
java -Xmx1024M -Xms512M -cp $HOME/bin/java/minecraft.jar net.minecraft.LauncherFrame &
MINECRAFT_PID=$!
sleep 1
#Then wait for minecraft to finish before relaunching ibus.
ibus-daemon -d
wait $MINECRAFT_PID
You can still use character input as normal in other windows or terminals.
What is also possible is to create an application launcher on a panel launching this script, and then you can directly launch minecraft without going through a terminal.
