It is my understanding that the proprietary Nvidia driver is more power efficient than the open source nouveau driver. However, I have not been able to boot Fedora 21 (F21) with it . I have tried using the driver straight and with Bumblebee . Both times, my computer failed to load GDM with errors like:
(EE) Failed to load /usr/lib64/xorg/modules/extensions/libglx.so: libnvidia-tls.so.346.35: cannot open shared object file: No such file or directory
"Oh no! Something has gone wrong!"
I am interested in the laptop being as power efficient as possible and also connecting to two external monitors. Is this possible? What is the recommended way to accomplish this?
