Bug Description
switcheroo-control fails to detect multi-gpu system. Running programs using discrete card still works using DRI_PRIME variable, but gnome-sell option to launch app using discrete gpu is missing. Logs contain following record:
switcheroo-control could not query vga_switcheroo status: Operation not permitted
I'm not sure that the problem is in switcheroo-control package itself, it might be somwhere deeper.
