I have hybrid graphics intel 520 HD and AMD R5 M335
I followed the wiki to power down AMD
I've installed acpi_call then run "modprobe acpi_call"
then "/usr/share/acpi_call/examples/turn_off_gpu.sh"
the output is
Trying \_SB.PCI0.P0P1.VGA._OFF: failed

any idea?

Help please

acpi_call last update upstream was almost 3 years ago (june 2013) , maybe your hardware is to new for it ?
Are you using AMD opensource or proprietary drivers ?
Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

I appreciate that you waited several days before bumping. A better approach to drawing attention to a thread would be to post what you have tried and read since your last post. You said you followed the wiki; you mightr consider removing any ambiguity by providing a link. Anything in the output of dmesg or in the journal?
I use pure Intel on my system and have never had to deal with hybrid graphics, so I've no experience to contribute beyond basic troubleshooting.

I use the opensource driver

Sorry for bumping
this is the wiki page that I followed https://wiki.archlinux.org/index.php/hy … e_Graphics
dmesg shows:
radeon 0000:01:00.0: VCE init error (-22).
[drm:r600_ring_test [radeon]] *ERROR* radeon: ring 0 test failed (scratch(0x850C)=0xCAFEDEAD)
[drm:si_resume [radeon]] *ERROR* si startup failed on resume
also glxgears shows that I have only 60FPS!! while intel HD 520 & AMD shoud be working, what's wrong?
I wish to get pure intel laptop but I didn't find a one

The 60 FPS is because most (if not all) videodrivers use Vsync and cap FPS at the refreshrate of your monitor.
If you really want, you can use vblank_mode=0 glxgears
The Hybrid Graphics page is somewhat out-of-date, PRIME and Bumblebee have advanced a lot.
For intel + amd setup with opensource drivers, use PRIME .
That page doesn't mention powering down the discrete card completely.
If you system has /sys/kernel/debug/vgaswitcheroo/switch then systemd-vgaswitcheroo-units should work for you.

Wow!
vblank_mode=0 glxgears gave me 7000FPS!
but I have lags when I move the windows,scrolling and when I use Wobbly windows effect it's so laggy (using TearFree option in /etc/X11/xorg.conf.d/20-intel.conf
make it better but not perfect) any idea to fix it?
And also DRI_PRIME=1 glxgears (from PRIME page) gave me 7000FPS
PRIME doesn't turn off AMD so my battery life still shows 1.5 hour of remaining time while it should show 3 hours (sometimes it actually shows 3 hours I don't know why!)
it sounds like that AMD working for few minutes and not working for another few minutes
