When it comes to laptops with hybrid graphics, discrete nvidia cards always created problems to everyone who used them in my surrounding. I have laptop which runs Debian 9 with intel and nvidia graphics, and intel is good enough for my daily tasks, so I would like to disable nvidia completely, so it wouldn't create heat or waste battery.
I found two possible solutions: first is to blacklist driver and/or turn it off in kernel parameters or something (like said
here), or I can use acpi_call to disable it's data bus, I think? (
check 'Fully Power Down Discrete GPU' article here).
So, which one of them still relevant? Which one of them will work better, and give me more battery time?
Thanks in advance.
