Minecraft Forums

I have tried uninstalling minecraft and deleting .minecraft, disabling my firewall, updating my graphics driver, restarting my computer and installing minecraft in a different location. None of these have fixed the issue that when I either run a pre-existing world or create a new one, the game always crashes.

Here's the crash report:

Alright I think that's everything, some help would be greatly appreciated.

Check the info on this page https://minecraftirc.net/support-articles/known-incompatible-software/

Has nothing useful on it but thanks anyway

Your issue is caused by something on that list, or software similar to those. Its a known issue, with a known cause.

Alright, well I've done everything for the programs on that list I do have and no dice so I'll have to look for "similar" apps

(Edit: Still have found nothing)

(bump)

I'm yet to find a solution, I'm seriously looking at formatting if nothing works

Run the program, choose "I accept", then "Do a scan and save a log file". After a while a text file will open. Copy everything, put the log on http://paste.ubuntu.com and give us the link.

I'm going to close this thread as I ended up formatting and now it's fine although I don't recommend anyone else doing that for minecraft.
