** Summary changed:
- Fails to load nvidia, fails to fallback to intel properly
+ nvidia fails, likely from xserver
** Description changed:
- Fresh install of 15.10, image of 09/06, only synaptic installed
+ Fresh install of 15.10, image of 09/06, only synaptic installed
Hardware is i7-4700MQ CPU, Intel® Haswell Mobile Nvidia GT770m
Initial bootup/ login is fine
Installed nvidia-352, install went fine, will attach log
Rebooted to a black greeter screen (heard sound
Logged in blindly, black screen
+ Attached logs seem fine
- rebooted, at black greeter screen went to tty, purged nvidia*, rebooted.
- Result was a login with no compiz, no unity as the OpenGl plugin was not
loaded nor from some further tests could be.
- The only way forward was to remove ~/.config/dconf/user from a tty, then
reboot
+ Downgrading xserver-xorg-core to 1.17.1 & nvidia works fine
Same machine runs nvidia driver via nvidia-prime fine in 14.04.3 & 15.04
