This bug was fixed in the package ubuntu-drivers-common - 1:0.2.91.6
---------------
ubuntu-drivers-common (1:0.2.91.6) trusty-proposed; urgency=medium
* UbuntuDrivers/detect.py, debian/tests/system, tests/ubuntu_drivers.py:
- Do not autoinstall the broadcom driver. The open driver should be a
better solution now (LP: #1306928), as the binary driver prevents
a number of systems from using the wireless card.
- Autoinstall linux-firmware-nonfree. This will help now that we no
longer autoinstall Broadcom's binary driver.
- Fix the relevant tests now that linux-firmware-nonfree has replaced
bcmwl.
* gpu-manager.c, tests/gpu-manager.py:
- Ignore CRT displays when using PRIME. This works around systems whose
BIOS provides a ghost output (LP: #1296020).
- Check that we don't remove xorg.confs on 1st boot (as per the
previous SRU).
- Try harder when loading bbswitch (LP: #1310023). If loading bbswitch
fails try with or without the "skip_optimus_dsm=1" option. Also, make
sure that we trim dmi resources or matching will give us false
positives.
- Switch to intel/SNA for optimus systems (LP: #1326257).
- Make sure to unload nvidia-uvm or nvidia won't be
unloaded.
- Make sure to walk properly the /dev/dri dir. This
prevents the program from stopping when, for example
/dev/dri/card1 is available while /dev/dri/card0 is
not.

Bug description:
SRU Request
Systems with Optimus (Intel+NVIDIA GPUs) can have problems with the
backlight (private bug #1290694) and when detecting and switching to
different resolutions (private bug #1285062). Using the intel driver
(with SNA) works better than the current solution (the modesetting
driver).
[Impact]
* Backlight control and resolution changes fail on some Optimus systems.
[Test Case]
* Select performance mode from the nvidia-settings panel and try to adjust
the backlight or to cycle through the available resolutions
- Expected: the backlight can be adjusted, and changing the resolution
works.
- Bad behavior: the backlight can't be adjusted and changing the
resolution can some times result in a black screen.
[Regression Potential]
* Low, as the intel driver is more feature complete than modesetting.
[Other Info]
* N/A
--
Running the proprietary nvidia drivers in an Optimus config works
(Intel+NVIDIA) can discover two issues:
1. Cannot adjust brightness in the guest session (private bug #1290694)
[Test Case]
* Switch to guest session and adjust brightness from settings or hotkey or
command line
- Expected: Can adjust the brightness
- Bad behavior: Cannot adjust brightness
2. Black screen while changing the resolution (private bug #1285062)
but switching to the guest session results in a black screen.
[Test Case]
* Go to display setting, set rotation to counterclockwise/clockwise/180
degrees and click apply
- Expected results: Can switch display rotation successfully
- Actual results: Black screen when switching display rotation
