I think my laptop, an Asus Rog Zephyrus G G4502, is unable correctly switch graphics card with prime-select. I'm trying to turn off the nvidia gpu for better battery life
Edit 1: The power consumption after running sudo prime-select nvidia && reboot is lower than running sudo prime-select intel && reboot.
Software and Updates recognises the Nvidia card and drivers. Nvidia Settings currently gives me this:
(nvidia-settings:11339): GLib-GObject-CRITICAL **: 14:27:26.898: g_object_unref: assertions 'G_IS_OBJECT (object)' failed ** Message: PRIME: No offloading required. Abort ** Message: PRIME: is it supported? no I've tried to purge and reinstall nvidia drivers a dozen times(even clean installs).
Without xorg.conf file, nvidia-settings shows a blank screen. With this file it shows some info about the gpu but no PRIME profiles tab.
