I am trying to get my hybrid graphics working properly. I have an Acer aspire E5-57G. Here is the info about my hybrid graphics as described by lspci -kv: Code (Text): 00:02.0 VGA compatible controller: Intel Corporation Sky Lake Integrated Graphics (rev 07) (prog-if 00 [VGA controller]) Subsystem: Acer Incorporated [ALI] Skylake Integrated Graphics Flags: bus master, fast devsel, latency 0, IRQ 130 Memory at 92000000 (64-bit, non-prefetchable) [size=16M] Memory at a0000000 (64-bit, prefetchable) [size=256M] I/O ports at 5000 [size=64] [virtual] Expansion ROM at 000c0000 [disabled] [size=128K] Capabilities: [40] Vendor Specific Information: Len=0c <?> Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00 Capabilities: [ac] MSI: Enable+ Count=1/1 Maskable- 64bit- Capabilities: [d0] Power Management version 2 Capabilities: [100] #1b Capabilities: [200] Address Translation Service (ATS) Capabilities: [300] #13 Kernel driver in use: i915 Kernel modules: i915 01:00.0 3D controller: NVIDIA Corporation Device 179c (rev ff) (prog-if ff) !!! Unknown header type 7f Kernel modules: nvidiafb, nouveau, nvidia_367, nvidia_367_drm I have followed the directions explained at https://mintguide.org/video/508-easily-switch-nvidia-hybrid-graphics-nvdia-intel.html and it seems like I *sort of* have my hybrid graphics working, at least as far as bbswitch can do it. But it doesn't work very well; for example, if the screen powers off after enough time of inactivity has elapsed, the desktop graphic is screwed up. For now, I have only the intel card active. But, as you can see from the lspci output, there's an issue with the recognition of the NVidia card. The relevant output of dmesg (I've included everything, and possibly more than necessary, regarding video) is: Code (Text): [ 1.563668] input: Video Bus as /devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/LNXVIDEO:00/input/input5 [ 1.563771] [Firmware Bug]: ACPI(PXSX) defines _DOD but not _DOS [ 1.563780] ACPI: Video Device [PXSX] (multi-head: yes rom: yes post: no) [ 1.563815] input: Video Bus as /devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/device:32/LNXVIDEO:01/input/input6 [ 1.563876] [drm] Initialized i915 1.6.0 20160711 for 0000:00:02.0 on minor 0 [ 4.227045] nvidia: loading out-of-tree module taints kernel.

The NVidia card was not working at all before this, but if I am going to use it at all, I would prefer that it worked properly! Thanks, Steve
