Re: [Bug 1706474] Re: gdm3 nvidia modeset=1 is broken, external screens don't work

2017-09-01 Thread Tim Richardson 
Good news from my side; I just updated everything on th ThinkPad W520, an
old Optimus laptop. the Uubntu 17.10 desktop now works with hybrid
graphics, prime sync and gdm3 using the latest updates (pre-release
channel). I have not added any PPAs so it's using the 375 driver currently
in the 17.10 repository.

Thanks Doug, that bug report is exactly as the nvidia forum so you and I

HI Doug, it could be hardware dependent although my two Optimus laptops are
very mainstream (both Quadro). It's more likely to be configuration (I hope)
How do you achieve modeset=1?  How do you confirm that you have Prime Sync
working? I use xrandr --verbose | grep PRIME

regards

Tim

Thanks, I look forward to it. It works with lightdm, though. What is GDM
doing that leads to a kernel panic, that lightdm does not do?

That;s even worse. I don't any working screen, no login.
This is not a trivial bug, I think, although I'd be happy for an easy
solution.

Re: [Bug 1706474] Re: gdm3 nvidia modeset=1 is broken, external screens don't work

2017-07-25 Thread Tim Richardson 
The problem is that Optimus (Nvidia's hybrid driver technology) requires
modeset=1 to use it properly so there are millions of laptop users who will
have a problem with this :)
https://devtalk.nvidia.com/default/topic/957814/linux/prime-and-prime-synchronization/

Plus it works fine with lightdm.
