I just did a fresh install of Ubuntu 15.04, and followed the instructions for installing the Ubuntu SDK located here: https://developer.ubuntu.com/en/start/ubuntu-sdk/installing-the-sdk/
On launching the SDK (or QT Creator), I receive the following error:
Welcome Mode Error:
Failed to create OpenGL context for format QSurfaceFormat(version 2.0,options QFlags(), depthBufferSize 24, redBufferSize -1, greenBufferSize -1, blueBufferSize -1, alphaBufferSize -1, stencilBufferSize 8, samples -1, swapBehavior 2, swapInterval 1, profile 0).
In case it was related to me having an NVidia card, I tried switching over to the proprietary NVidia drivers, but am still receiving the error.
I found a post where somebody suggested that a fix for this in QT Creator is to go into the 'help > about plugins' menu in the application and disable the welcome screen, however both QT creator and the Ubuntu SDK hang before I can get to the option through the GUI.
Since I can't get that fix to work, and the official documentation just assumes everything works, I'm somewhat at a loss. If anybody could suggest anything to check, or any packages I need to install that weren't in the documentation, I'd greatly appreciate it.
