hello everyone!, i am having issue switching off the discrete NVIDIA graphics card in mint . previously i was using elementary-os and i could switch off the power to discrete graphics card by :
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch. but this isn't working in case of MINT : cat /sys/kernel/debug/vgaswitcheroo/switch : IGD(integrated graphics) : pwr DIS(discrete graphics) : Dyn-pwr DIS-Audio : pwr even if i issue the command there's no change . the power doesn't turn off. Also there was no DIS-Audio in elementary-OS and DIS only showed "pwr" instead of "DYN-pwr".
