Hello!

Today, after an update of Ubuntu 14.04 I had the error message reported in this bug: "bbswitch: No discrete VGA device found".
Yesterday when I installed the latest updates availble I noticed that it was installing nvidia-331-updates*, nvidia-libopencl-*, nvidia-prime and nvidia settings.

Ok, the problem is that I don't have a NVIDIA card, but an AMD... I'm not using the proprietary blob.
To "solve" the problem, just purged the nvidia packages, rebooted and now the system is working again!

To others with the same problem: 
If you were unable to login because you card was not recognized and you dont have a NVIDIA card like me do the following steps.
1 - Use ctrl + alt + 1 to jump to a terminal window (mine was still working).
2 - Login with your accout
3 - Type the command: sudo apt-get purge nvidia* and accept
4 - Reboot the system.

I hope this will help somebody!
Bye!

Title:
  bbswitch: fails to find ACPI handle for discrete card

Status in bbswitch package in Ubuntu:
  Invalid

Bug description:
  Hi,

  I have a GeForce 9600 GT discrete card providing a third monitor on my
  14.04 Trusty system. The first two monitors are connected to the
  onboard Intel i7-3770 HD graphics.

  This is a contiunation of launchpad bug #1310023, where Alberto Milone

  You can find full debug logs in ticket #1310023, but briefly,

  bbswitch-dkms package version 0.7-2ubuntu1

  dmesg:

  $ lspci | grep VGA
  00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor Graphics Controller (rev 09)
  01:00.0 VGA compatible controller: NVIDIA Corporation G94 [GeForce 9600 GT] (rev a1)

  
  fyi as per the previous ticket I upgraded ubuntu-drivers-common to version 1:0.2.91.6 from trusty-proposed, but as in comment 23 there the same "cannot find ACPI handle" was present in dmesg before upgrading that package.

  
  The machine is dual boot with Windows 7, on the Windows side of things the three monitor setup works fine.

  
  ?

  thanks,
  Hamish
