I have tried With Xenial 16.04 Linux Kernel 4.3 and The issue is still there. Now Something Interesting.
I have a Lenovo z50-70 Laptop with Hybrid Graphics. So II have to use Bumblebee for getting proper use of the Nvidia Card on the Laptop. I have to first use nomodeset kernel parameter to even boot up. Then Once In install bumblebee and things look great. However the moment I use bumblebee for Launching any application, Something changes, Not sure what. and next reboot produces this black screen and the Intern DRM messages. I remove bumblebee nvidia etc.... nothing helps. I keep getting this black screen. So Things work great if I don't use bumblebee at all, I can reboot system etc... No worries, However the system breaks with the first reboot after using Bumblebee to launch any app for the first time. Even if I ran glxinfo | grep OpenGL with primusrun or Optirun. Things no longer stay the same. The session carries on fine, However the moment I reboot the machine/Restart X. Things are black. I think there is a regression somewhere with Bumblebee breaking the Intel OpenSource Driver. Or maybe Nvidia -Closed Source Driver breaking Intel Driver... Honestly I can't figure it out. I hope this helps in understanding the behaviour of the problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1492764 Title: [drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in ips_enabled (expected 1, found 0) To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1492764/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
