I've had a stable Linux Mint machine for almost 5 years now. Sadly my integrated graphics card has gone haywire... I ordered a new mobo from Dell to replace it, but I'm trying to stabilize my machine while I wait for the part. If I boot into safe mode, everything works perfectly although video hardware acceleration is disabled. If I boot normally, my current settings are to use the integrated GPU, so past the splash screen I get triangular colourful garbage that resembles abstract art.
I'd like to try to completey disable the integrated GPU so that the system regains stability and performance using the dedicated GPU... I know battery life will suffer, but at least I'll have a computer to work with. In my current setup, I had an applet in the dock that allowed me to manually switch between integrated, dedicated, or hybrid graphics mode. However I'm unable to boot into the OS and change this setting, and when I change it in safe boot mode, it doesn't save that setting when I boot back normally. Is there a way to do this from grub or from safe mode terminal? This is the System Info from within safe mode, and the lspci call:
