After having followed the instructions in http://www.if-not-true-then-false.com/2015/fedora-nvidia-guide/, I installed the latest stable Linux driver (352.79) on my new Lenovo Thinkpad P70 w/ Quadro M3000M card, running on Fedora 23 (x86_64). With the nouveau driver disabled/blacklisted and with ‘Discrete Mode’ set in the BIOS (i.e. as opposed to “Hybrid Mode”, enabling Optimus), when I attempt to boot to X, the system hangs with the CapsLock key blinking.
I can boot to RC3 fine w/ the nvidia driver loaded - but not RC5. When I tried starting X from RC3 (i.e. w/
startx -- -logverbose 6), the same behavior (CapsLock blinking, system hangs) occurred. I could not SSH into the system to capture the nvidia-bug-report.log.gz: I was only able to capture it when running w/out X.
I have tried installing addt’l drivers (long-lived, short-lived, and beta) with no success. I’ve also tried multiple kernels (w/ and w/out noapic/acpi=off flags), tested using legacy BIOS and newer UEFI, and tested against addt’l distros (mainly CentOS 7). The nouveau driver (in conjunction w/ Optimus aka. “Hybrid mode” in BIOS) seems to work fine on kernel 4.4.0 (more unstable on earlier versions), but the proprietary NVIDIA driver has not yet worked. Any help would be greatly appreciated.
