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.

14.04: Nvidia Prime is unable to switch to the Nvidia card

Bug description:
SRU Request
On some systems bbswitch requires the "skip_optimus_dsm=1" option in
order to load properly. So far we have dealt with this problem with
system specific quirks based on DMI information. This some times gives
us false positives or doesn't cover all systems (it's hard to quirk
all systems). We should simply try with and without that option and
use whatever works best for the system. This should cover all cases
with no need for additional quirks.
[Impact]
* Loading bbswitch with the wrong option causes the module to fail from
loading which, in turn, prevents hybrid graphics from working properly.
[Test Case]
* Install the nvidia binary driver, reboot, and check that the NVIDIA GPU is
enabled (attach your /var/log/gpu-manager.log)
- Expected: the NVIDIA GPU is enabled.
- Bad behavior: the system switches back to the intel driver and the
NVIDIA GPU is not used.
[Regression Potential]
* Low. Systems that currently work will keep working as usual, the ones that
currently fail should finally work.
[Other Info]
* N/A

I did a fresh install of 14.04 the day it was released. I use a XPS 15z
laptop form Dell with hybrid graphics (Intel HD 3000 (probably) and Nvidia
Geforce GT 525M). Booting doesn't work out of the box, but by setting
GRUB_CMDLINE_LINUX_DEFAULT="acpi_backlight=vendor dell_laptop.backlight=0
quiet splash"
in /etc/default/grub it works. acpi=off when installing, removed that from
the grub file when installed.
I expected that the Prime feature introduced in kernel 3.12 (kernel
3.13.x here) would let me switch between the Intel and Nvidia cards as
i like, instead of using Bumblebee, which doesn't work properly with
everything. I've installed and tried both the nvidia-331 and
nvidia-304 drivers. Exactly the same result from both.
Attempting to switch to the Nvidia card in nvidia-settings (tried on almost
all of the drivers available, including 331.38) resulted in an error message,
in a new window, with no text.
prime-switch in terminal gives this output: Segmentation fault (core dumped)
Sudoing the process gives no output at all. No graphical performance boost
either, still the Intel card...
sudo prime-select nvidia gives this output:
Error: alternatives are not set up properly
Error: nvidia mode can't be enabled
I've also tried Bumblebee (not PPA) a few times, but it's also unable
to switch.
I'm able to use the Intel card temporary, but I would really like to
be able to use the full power of my computer...
