In the system you have, it doesn't appear to be switchable - some outputs are only controlled by Intel, some outputs are only controlled by nvidia. If you want to see anything on the panel, you need to enable Intel. As the igfx is also the one used by the BIOS, it is declared the primary GPU and so will always be active.

[Oláh Balázs (balazs-freedom)]

It has worked until the latest update. It was switchable. Worked like a charm.

When I selected Intel, my laptop was super cool, and could run from battery for 7-8-9 hours.
When I selected Nvidia, it was hotter, but I could play windows games through wine with high FPS.

Now after latest kernel update I get an error if I try to switch using nvidia-settings. And laptop heats. Can only run 2 hours from battery.

"nvidia-settings -q screens -q gpus -q framelocks -q vcs -q gvis -q fans

1 X Screen on Inspiron:0

    [0] Not NVIDIA (Unknown)
"

[Oláh Balázs (balazs-freedom)]

Kernel updated came again. System started with a crash: "Unable to insall nvidia-331".

nvidia-331 331.38-0ubuntu4: nvidia-331 kernel module failed to build.

https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-331/+bug/1268257

In nvidia-settings it showed correctly that my nvidia card is turned on and I was able to switch back to Intel. Will try Nvidia after next update.

[Chris Wilson (ickle)]

Right, you don't want nouveau installed in this case, which it currently is.

Status changed to 'Confirmed' because the bug affects multiple users.

Oláh Balázs, as per http://www.dell.com/support/home/us/en/04/product-support/product/inspiron-15r-n5110/drivers/advanced an update to your computer's buggy and outdated BIOS is available (A11). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?

If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report.

Once the BIOS is updated, if the problem is still reproducible, and the information above is provided, then please mark this report Status New. Otherwise, please mark this as Invalid.

Thank you for your understanding.
