I’ve updated to kernel 4.5 and nvidia-361 today, to see if the new patches regarding vsync issues are there already.
But after the update I can’t even switch anymore:
sudo prime-select nvidia Error: alternatives are not set up properly Error: nvidia mode can't be enabled
prime-select query unknown
update-alternatives --list i386-linux-gnu_gl_conf /usr/lib/i386-linux-gnu/mesa/ld.so.conf /usr/lib/nvidia-361-prime/alt_ld.so.conf /usr/lib/nvidia-361/alt_ld.so.conf
When I use the nvidia settings tool, it seems that intel is enabled, but when I switch to nvidia, I get an error dialog without any actuall error message (just a red exclamation mark).
Tried various solutions from the web, including purging / reinstalling the drivers. Nothing worked.
Any help would be appreciated!
EDIT: Maybe that is of use?
sudo nvidia-settings ** Message: PRIME: Requires offloading ** Message: PRIME: is it supported? yes ERROR: nvidia-settings could not find the registry key file. This file should have been installed along with this driver at /usr/share/nvidia/nvidia-application-profiles-key-documentation. The application profiles will continue to work, but values cannot be prepopulated or validated, and will not be listed in the help text. Please see the README for possible values and descriptions.
EDIT 2: I’m on Kubuntu 14.04 LTS 64bit, ACER V3-772 Laptop with Geforce 750m and i5-4200m
EDIT 3: I rolled back to 358, but the issue remains. Seems to be kernel related…
