I clicked fullscreen and the screen went black and I could not get out, I had to force exit, now I cannot play minecraft because whenever I click play on the new launcher I get the mojang symbol then my entire screen turns black.

This is very weird if any of you can find a way to fix it, or know what the problem is, please tell me, by the way this is the launcher in the development console mode from when I click start to when I have to use command Q.

Try updating the drivers for your graphics card.

I forgot to mention f11 does not work the exit fullscreen

I also have all the software updates

Duplicate of MC-6665

how is this a duplicate? The other one i on windows and is about the game crashing?
Wait ill re check sorry if I am wrong 😛

I just really want to be able to get back onto minecraft and ride some horses🙂

Sorry. Very unprecise description.

Try:

• Quit Minecraft

• Locate Minecraft folder http://hopper.minecraft.net/help/finding-minecraft-data-folder/

• Open the file options.txt with a text editor,

• Change the line fullscreen:true to fullscreen:false

• Save the file

• Start Minecraft

At least you can play that way in windowed mode.

ok thank you
I will update you on the situation if I have more troubles with this
