Same thing with a lenovo IdeaPad Y580 (sandybridge) except there it doesn't even make it the low graphic pop up.
In both cases (sandybridge & previous laptop which is haswell) if I install the nvidia drivers & reboot, it does boot up to an ubuntu session. From there switching via prime profiles to intel gpu works & survives a reboot. So the issue is on an upgrade of xserver while on the Intel iGPU, maybe how alternatives are set? Also to report that when the nvidia drivers are used via nvidia-prime the current lack of any vsync is Not solved at all.. ( logs look good for prime synchronization, just doesn't work. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1671799 Title: FFe: xserver 1.19.x Status in xorg-server package in Ubuntu: Confirmed Bug description: xserver 1.19 has been out for quite some time now, and xmir has been recently ported to it so we can push 1.19 to zesty now.
