Description Mansoor Ahmed 2017-06-11 22:43:54 UTC 
Installing Nvidia driver and then switching to Intel graphic card causes the system to freeze and the fan rotate at full speed. The only way I manged to avoid this problem is by adding the follwing kernel paramters: 

acpi_osi=! acpi_osi="Windows 2009"


Details: 

Whenever Nvidia driver is installed, as long as the user doesn't switch to Intel graphic card from nvidia-prime, things work fine. When the user switches to Intel graphic card from nvidia-prime and logout, the system crashes and every time this happens the user had to force shutdown the machine. When rebooting, the same thing happens, the system freezes and the user had to force shutdown the machine again. 

This is a link to Nvidia devtalk forum where multiple users reported the same problem:

Specifically Nvidia driver 375 version 375.66 and lower versions.

Please contact Nvidia for support for their nvidia driver --
as it is not open source, and not part of the upstream linux kernel.

Indeed, when their driver is loaded, the kernel is tainted
and no part of it can be supported by anybody besides Nvidia.

Consider the open source nouveau driver, as an alternative.

Contacting Nvidia did little help. It just resolved my problem, but still the bug is there. www.devtalk.nvidia.com was the only solution I got. When Nivida was contacted officially they utterly refused to resolve the problem and referred me to devtalk, their forum. It's absolutely ridiculous.

> It's absolutely ridiculous.

I think the word you are searching for us "unsupported".
