I have installed Arch Linux on a Dell Inspiron R15 with hybrid Intel/AMD
graphics. vga_switcheroo is enabled and I can control radeon power with "echo
ON/OFF > /sys/kernel/debug/vgaswitcheroo/switch".
But when I try to switch to radeon in console with "echo DIS >
/sys/kernel/debug/vgaswitcheroo/switch" the screen turns off.
I can switch back to intel with "echo IGD >
/sys/kernel/debug/vgaswitcheroo/switch" by blind typing it, and then the screen
turns back on.
