Not sure if this is the right place... OS: Ubuntu 15.04, Using oibaf PPA. Laptop: Asus N56VZ I have GT650M with Intel. The nouveau driver doesn't seem to load with this error in /var/log/Xorg.8.log: NOUVEAU(0): [drm] failed to set drm interface version. Googling, I've found people with the same issue, but no solution that is not "use the proprietary drivers" which is I prefer not to do as they are quite fragile during upgrades. With earlier kernels (about 3 releases of Ubuntu back?) - Nouveau worked fine with bumblebee, it hasn't for quite a long time, I've got a suspicion that Nouveau and Bumblebee hasn't been working for anybody else during that time too (since searching for a fix on and off the last few years). /var/log/Xorg.8.log [ 8990.687] X.Org X Server 1.17.1 Release Date: 2015-02-10 [ 8990.687] X Protocol Version 11, Revision 0 [ 8990.687] Build Operating System: Linux 3.2.0-61-generic x86_64 Ubuntu [ 8990.687] Current Operating System: Linux beezlebub 3.19.0-20-generic #20-Ubuntu SMP Fri May 29 10:10:47 UTC 2015 x86_64 [ 8990.687] Kernel command line: BOOT_IMAGE=/vmlinuz-3.19.0-20-generic.efi.signed root=UUID=14ac372e-6980-4fe8-b247-fae92d54b0c5 ro quiet splash acpi_enforce_resources=lax intel_pstate=enable rcutree.rcu_idle_gp_delay=1 vt.handoff=7 [ 8990.687] Build Date: 19 March 2015 09:26:59AM [ 8990.687] xorg-server 2:1.17.1-0ubuntu3 (For technical support please see http://www.ubuntu.com/support) [ 8990.687] Current version of pixman: 0.32.6 [ 8990.687] Before reporting problems, check http://wiki.x.org to make sure that you have the latest version.

My guess is that there are errors in dmesg around gpu init. Perhaps you can avoid them by turning off runpm (nouveau.runpm=0).
Keyword here is Bumblebee. Can you try without it for your first try. Additionally you can try Ilia's suggestion, but please provide the complete output of dmesg in either case.

Nouveau is not being loaded. Perhaps your distro has helpfully blacklisted it. This is why the DDX can't find the device.
Ah, OK. I think bumblebee has it blacklisted. I can run the module with modprobe, but it doesn't seem to help ? I'll try unblacklisting it and rebooting.

primusrun does the same thing as optirun, kicks me out to login screen the first time, then the drm version error. Have uploaded new logs from after I got kicked to login screen + logged back in.
Using anything relating to primusrun, optirun, bumblebee, etc is entirely unsupported by nouveau. Feel free to ask those projects for support. Your Xorg.0.log shows that nouveau got detected as a secondary GPU and that it detects your HDMI-1 screen just fine. If you follow the steps at http://nouveau.freedesktop.org/wiki/Optimus/ then it should all work.
Seems like the short version was too brief, here is a longer one: Bumblebee likes to disable/pull out the card from under the kernel driver to safe power. On the userspace it uses a form of GL/GLX proxy. If you're using recent kernel/mesa you don't need any part for Bumblebee, as the kernel driver will automatically power up/down the device. On the userspace, use $DRI_PRIME=1 glxgears to start glxgears with the "other" (nvidia) card, or just $glxgears to use the integrated (intel) one. nouveau.runpm=0 disables the automatic power up/down. You might want to experiment if things work without it.
glxgears seems to work, glxspheres showed a black window glxgears - no prime, works $ glxgears -info Running synchronized to the vertical refresh. The framerate should be approximately the same as the monitor refresh rate.

Created attachment 117025 [details] glxdemo with dri prime looks a bit glitchy Just noticed this glitchyness.
Changing the intel driver to use SNA seems to have fixed the black window problem AND the glitchyness in glxdemo when using DRI_PRIME=1 I followed advice here https://ask.fedoraproject.org/en/question/32960/black-windows-in-gnome-3-suddenly/ and set /etc/X11/xorg.conf to this below. - anyone on optimnus having similar problems should probably try this. - In the meantime this bug can be closed.
