Bug Description

GPU: Nvidia GeForce GT440

When I try to run the demo mir server basic or the mir server shell, my desktop freezes, I can't switch tty (not even through ssh) and I get the message:

"gbm: failed to open any driver (search paths <the paths of my drivers /usr/lib/...>)"

This message comes from mesa (libgbm).
I have confirmed that the paths are correct and contain the nouveau_dri.so.

The nouveau drivers are installed in my system and they are loaded when I get the freeze (if I run lsmod I see the nouveau modules in the list).

I've just tested a:
 NVIDIA Corporation GT218GL [Quadro FX 380 LP] (rev a2)
on trusty (fully updated) and Mir works with nouveau better than ever :)

A few questions then:
  1. Are any packages on the system non-standard (built by you)?
  2. Do you accidentally still have any traces of a proprietary NVIDIA driver installed?
  3. Does X/Compiz work well on this system? (i.e. Unity blurs work).

Maybe try reinstalling all the official Ubuntu mesa packages? And when possible, reinstall the whole system fresh from a trusty daily image? Because all signs so far indicate it's most likely a problem with your installation.

When I have time I will try another Nvidia system.

Tested a second NVIDIA card: GeForce 210 and Mir still works perfectly.

Of course, the error message you're seeing still sounds like it's your system (Mesa packages) somehow broken.

Interestingly, someone else just logged what looks like the same bug but with Intel graphics now: bug 1292675

As bug 1292675 contains more attachments and debugging information I'm going to make that the master bug. This one becomes a duplicate.
