I have a dell notebook, on which so far managed to install gentoo.
here is my lspci:
Code:
00:00.0 Host bridge: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor DRAM Controller (rev 06)

00:14.0 USB controller: Intel Corporation 8 Series/C220 Series Chipset Family USB xHCI (rev 04)
00:16.0 Communication controller: Intel Corporation 8 Series/C220 Series Chipset Family MEI Controller #1 (rev 04)
00:19.0 Ethernet controller: Intel Corporation Ethernet Connection I217-LM (rev 04)

00:1b.0 Audio device: Intel Corporation 8 Series/C220 Series Chipset High Definition Audio Controller (rev 04)
00:1c.0 PCI bridge: Intel Corporation 8 Series/C220 Series Chipset Family PCI Express Root Port #1 (rev d4)
00:1c.2 PCI bridge: Intel Corporation 8 Series/C220 Series Chipset Family PCI Express Root Port #3 (rev d4)
00:1c.4 PCI bridge: Intel Corporation 8 Series/C220 Series Chipset Family PCI Express Root Port #5 (rev d4)
00:1c.5 PCI bridge: Intel Corporation 8 Series/C220 Series Chipset Family PCI Express Root Port #6 (rev d4)

00:1c.7 PCI bridge: Intel Corporation 8 Series/C220 Series Chipset Family PCI Express Root Port #8 (rev d4)
00:1d.0 USB controller: Intel Corporation 8 Series/C220 Series Chipset Family USB EHCI #1 (rev 04)
00:1f.0 ISA bridge: Intel Corporation QM87 Express LPC Controller (rev 04)
00:1f.2 SATA controller: Intel Corporation 8 Series/C220 Series Chipset Family 6-port SATA Controller 1 [AHCI mode] (rev 04)

01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Mars XTX [Radeon HD 8790M]
03:00.0 Network controller: Intel Corporation Centrino Advanced-N 6235 (rev 24)
0e:00.0 SD Host controller: O2 Micro, Inc. SD/MMC Card Reader Controller (rev 01)

Right now, i only have the kernel modules for the integrated intel card.
It has surprisingly good performance, but it's obviously not on the level of the radeon card.

I have read around, and it people say that it's not possible or i will get a performance hit if i enable hybrid graphics?
Or can i just have 2 grub entries, where i disable one of the cards?

do first a
Code:
lspci -k
and than with each number that you can see absolutely left in front of your VGA adapters do
Code:
lspci -s xx:xx.x -k

xx:xx.x is the number in front of your VGA cards

and give us this output
