[sloved]Arch kernel didnt have Vga switcheroo?

When I type these in terminal

# cat /sys/kernel/debug/vgaswitcheroo/switch

cat: /sys/kernel/debug/vgaswitcheroo/switch: No such file or dictionary

should I make my own kernel?

Re: [sloved]Arch kernel didnt have Vga switcheroo?

Well it seems to be enabled in the kernel config, have you had this working on a previous distro?
Have you checked that you've got switchable graphics enabled in the bios?

EDIT: I'm assuming your system is up to date and you're not using the -lts kernel?

Maybe this https://wiki.archlinux.org/index.php/Bu … switcheroo will help.
debugfs has to be mounted, /sys/kernel/debug/ is empty otherwise.

I already enabled switchable in the bios

and also

I have already blacklist the radeon in the rc.conf

and in the  /etc/modprobe.d/radeon.conf

I add this

options radeon modeset=0

btw  hybrid card never worked on any distro I used before

intel i3 and ati HD 6630

Blacklisting in rc.conf is deprecated.

If I blacklist radeon in my rc.conf

is my ati card still working when I boot my laptop?
I mean will it cost power using?

Blacklisting in rc.conf doesn't do anything, it doesn't blacklist at all.

and if it doesn't, you can try this ? https://bbs.archlinux.org/viewtopic.php?pid=951136  post #4
For me it is better than just blacklisting the radeon module as your discrete card is really off.
