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 Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1671799 Title: FFe: xserver 1.19.x To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1671799/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
