Cannot find ACPI handle for VGA device #167

Open alferum opened 6 years ago

alferum commented 6 years ago

Hi,

I have a bug with bbswitch version 0.7 and 0.8 on Debian 9 Stretch and Debian 10 Buster .

I am using C847MS-E33 with integrated Intel CPU C847 (built-in graphics capabilities), and NVIDIA Geforce GTX 960.

$ sudo dmesg
bbswitch: version 0.8
bbswitch: Found integrated VGA device 0000:00:02.0: \_SB_.PCI0.GFX0
bbswitch: cannot find ACPI handle for VGA device 0000:01:00.0

It's not work with kernels 3.16.0-5-amd64, 4.9.0-3-amd64, 4.9.0-6-amd64, 4.14.0-0-amd64, 4.15.0-2-amd64.

Can you try with the upstream kernel without Debian patches?

It's not work with kernel without Debian patches too, build linux-4.15.tar.gz

My computer is desktop, so bbswitch does not work probably. For me, bumblebee works without bbswitch. Thank you everyone. You can close this issue.

Having exactly same issue here on Lenovo Carbon X1C6 with Lenovo Thunderbolt 3 Graphics Dock.

This is still an issue in Debian Buster and Bullseye:
