X11 keeps booting in failsafe mode due to xorg.conf having the nvidia set as primary GPU.

[Omega-xis]

removing the nvidia-driver and /etc/X11/xorg.conf and manually launching lightdm from the command-line solves it.

every reboot results in having the following contents in /etc/X11/xorg.conf

Section "ServerLayout"
    Identifier "layout"
    Screen 0 "nvidia"
    Inactive "intel"
EndSection

the intel section also displays "none" as acceleration method.

Status changed to 'Confirmed' because the bug affects multiple users.

there is a workaround to this.
install the nvidia-prime package and type
"sudo prime-select intel" this will force the intel GPU.

Omega-xis, thank you for reporting this and helping make Ubuntu better.

Could you please run the following command once from a terminal by ensuring you have the package xdiagnose installed, and that you click the Yes button for attaching additional debugging information:
apport-collect -p xorg 1508573

hi there.

I managed to fix this by installing the nvidia-prime package and tweaking the bumblebee config files a little.
this is weird though since on previous versions of ubuntu the installation of the nvidia-prime package used to break bumblebee, but the same thing that breaks it apparently fixed it too. My Geforce GTX840M still can't run on the nvidia itself (using prime-select) but bumblebee works, so it's not a big deal anymore. Bumblebee is however broken when I put my laptop to sleep mode, since the discrete GPU is turned off but doesn't get back on again. a reboot fixes this, but that's for another bug.
Do you still need the xdiagnose information? because I will happily provide it for you since I've had so many issues with hybrid graphics before and I really want this solved once and for all! I guess vulkan will fix this soon.

I'm not a bumblebee expert by any means, but perhaps at least the documentation would need to be updated to include your use case noted at https://wiki.ubuntu.com/Bumblebee ? What do you think?

>"My Geforce GTX840M still can't run on the nvidia itself (using prime-select) but bumblebee works, so it's not a big deal anymore."

Were you expecting it to work with nvidia itself via prime-select?

>"Bumblebee is however broken when I put my laptop to sleep mode, since the discrete GPU is turned off but doesn't get back on again. a reboot fixes this, but that's for another bug."

Yes. Please feel free to file a new report about that via a terminal:
ubuntu-bug xorg

Please feel free to subscribe me to it.

>"Do you still need the xdiagnose information? because I will happily provide it for you since I've had so many issues with hybrid graphics before and I really want this solved once and for all! I guess vulkan will fix this soon."

Anything that isn't the scope of this report, would need a separate report, one report per distinct issue.
