I have a Lenovo Thinkpad e540 laptop with dual graphics, Intel integrated and Nvidia GT 740m Discrete. After changing from
nouveau drivers to Nvidia binary driver 346.82 proprietary before login screen I've got a message:
[0.646495]Error parsing PCC subspaces from PCCT [0.646521]ACPI PCC probe failed.
3.19.0-26-generic #28~14.04.1-Ubuntu SMP Wed Aug 12 14:09:17 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
I've read somewhere that if I put in grub file
quiet splash nomodeset that will fix this, but that doesn't work for me, then I get into login loop.
How can I fix this?
