bbswitch cannot switch OFF nvidia card after update to kernel 3.10.0-229.1.2.el7.x86_6

[jeannotalpin]

Since last update of CentOS 7 (1503) and therefore kernel change to 3.10.0-229.1.2.el7.x86_64, bumblebee and bbswitch are not able to turn off nvidia card. Discrete card works fine but bug leads to high battery consumption. Everything was working fine on previous release. Method described here: http://elrepo.org/tiki/bumblebee used to install bumblebee.

Do you still have this issue?

[jeannotalpin]

Problem is still present with kernel 3.10.0-327.4.4.el7.x86_64: [ 639.290565] bbswitch: disabling discrete graphics [ 639.290577] ACPI Warning: SB.PCI0.PEG.VID._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires Package

This branch https://github.com/smunaut/bbswitch/tree/hack-t440s seems to fix the problem though.

[ArchangeGabriel]

OK, then it’s a duplicate of https://github.com/Bumblebee-Project/bbswitch/issues/112.
