Title:
booting with nvidia drivers via nvidia-prime results in no display in
14.04.5
Status in nvidia-prime package in Ubuntu:
Confirmed
Status in ubuntu-drivers-common package in Ubuntu:
Fix Released
Bug description:
Pretty simple & not unknown.
Test case:
Optimus laptop
14.04.5 install or 14.04.x upgraded to lts-xenial HWE stack
Install nvidia drivers, reboot
Upon reboot the greeter screen will be blank though the bell will be heard.
Wait 300+ sec. for idle time out, then wake machine up
At that point the display is enabled & will be such for the life of the login
session.
Solutions:
1. patch ubuntu-drivers-common to use modesetting for intel (very poor choice
I'd think
2. reduce the idle time out in unity-greeter.gschema.xml to 3-4 secs. (
another poor choice but could inadvertently help out, particularly with #4
3. fix this issue ( likely not possible
4. pre-warn users/upgraders in a 14.04.5 release/upgrade note
5. provide a patched lts ubuntu-drivers-common only for 14.04.5 HWE
