OK, I think I know what the problem is. Sorry, I probably could have picked this up from your original post a couple of months ago, I just didn’t spot the clue:
OpenGL vendor string: VMware, Inc.
I didn’t realise you were running this within a virtual machine. As discussed in this post, I don’t expect this to work - MRView is designed to run on and have direct access to modern rendering hardware, but virtual machines will by necessity introduce an abstraction layer. But it seems it might be possible with a recent version of VMware, and a recent version of Linux (the mesa libraries in particular). So you’d need to update your VMware installation to the latest version, just to make sure, and update your Linux install also: I note you’re running mesa 11.0.7, and if you look through the post I mentioned earlier, I think you need at least version 11.1 for this to work. I’ve no idea how difficult it might be to update just the mesa part on your Linux distribution, but there’s bound to be lots of information about this online if you search for it…
