I'm not quite sure what QtMir is doing to trigger this. I've tried hacks to Mir directly to try and emulate what it might be doing, but my hacks result in nested servers starting and running perfectly still.

Also, you shouldn't need a depth buffer for a desktop either. Throwing away that whole MirGLConfig, or at least loosening the restrictions should solve the problem. ** Also affects: qtmir (Ubuntu) Importance: Undecided Status: New ** Changed in: qtmir (Ubuntu) Importance: Undecided = Critical ** Changed in: qtmir (Ubuntu) Status: New = Triaged -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1408910 Title: Ubuntu Desktop Next fails to start; just black screen and mouse pointer (unity8.log: std::exception::what: Failed to create shared EGL context) To manage notifications about this bug go to: https://bugs.launchpad.net/mir/+bug/1408910/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Tested with mir-demos on the affected machine. Nesting works just fine
with the mir-demos.
This bug then is just Unity8/QtMir choosing EGL config modifications
that i945 systems can't support. Looking at the QtMir code, I would
hazard a guess that the request for 8 bit stencilling is unreasonable:
class MirGLConfig : public mir::graphics::GLConfig
{
public:
int depth_buffer_bits() const override { return 24; }
int stencil_buffer_bits() const override { return 8; }
};
