Minecraft Forums

I had no problems until I fiddled with my Nvidia X server so that I could get a second monitor to work. After I worked on that, minecraft worked once then wouldn't work again.

I am running Ubuntu 12.04 on a Dell XPS 15z Laptop.

Heres the Crash Report:

I found another guy on this forum who had the same issue, but he fixed it by updating to 13.04 (Which I don't want to do)

Any help will be much appricated.

shamelessly bumping this...

What was wrong was that the driver for my graphics card was not working properly.
I used Sudo apt-get autoremove (Driver)
then after the driver was gone, I used sudo apt-get install (driver)
in my computer it was the nvidia-common and the nvidia-prime drivers.
