ROSA Linux Bugzilla – Bug 5528
Bumblebee disables the discrete graphics card in BIOS
Last modified: 2015-07-07 23:18:17 MSD
Description of problem:
The bumblebee package disables the discrete graphics card in BIOS after second reboot, so you can't find it in the output of lspci. The discrete card works fine only for one boot after installation of bumblebee. The card can be fixed by manual reset of BIOS settings. But it will be disabled again on the next boot.

Setting TurnCardOffAtExit to false in /etc/bumblebee/bumblebee.conf fixed the issue.

The XFdrake should be fixed properly to prevent the card power off.
Fixed in the latest version of drakx-kbd-mouse-x11.
