I have an intel/nvidia hybrid graphics laptop (Asus N56JR) that works perfectly well under the Intel display driver, but fails under nouveau and nvidia. Here's the relevant configuration:
[astex@dingo ~]$ lspci | grep 3D
01:00.0 3D controller: NVIDIA Corporation GK106M [GeForce GTX 760M] (rev a1)
[astex@dingo ~]$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)For nvidia, there are no error messages in either dmesg or journalctl, my display simply flickers several times (as though KMS is being initialized), boot seems to succeed completely, but there's simply no X session tied to my display.
But I'd prefer to use nouveau anyway. Nouveau displays a few errors during boot, but bumblebee seems to recognize it properly and I can turn the card on/off with bbswitch. Unfortunately, optirun fails with the following:
[astex@dingo ~]$ optirun -vv glxinfo

It's awfully similar to this (https://bugs.freedesktop.org/show_bug.cgi?id=70354), but I've never patched a kernel module before (maybe now's a good time to start?).
