EDIT: I realize this probably should have gone under "Hardware and Kernel" section now. Oops.

Attempting to get proper graphics drivers going, I've got a Dell Inspiron 7510 with Intel 520 integrated and an Nvidia M1000M Quadro, kernel options are set to accept 8xx/9xx/G3x/G4x/HD drivers, no Nvidia kernel options are set (intend to use non-free Nvidia drivers with Bumblebee), VIDEO_CARDS in make.conf is set to "intel i965", performed a --changed-use --deep @world emerge
Built mesa-progs to get glxgears and glxinfo
glxgears yields:
Code:
Error: couldn't get an RGB, Double-buffered visual

glxinfo yields:
Code:
name of display: 0
Error: couldn't find RGB GLX visual or fbconfig


Feels like I'm missing a simple config somewhere?

Output of lspci -k | grep -iA3 vga :
Code:

00:02.0 VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06)
   Subsystem: Dell HD Graphics 530
   Kernel driver in use: i915
00:04.0 Signal processing controller: Intel Corporation Xeon E3-1200 v5/E3-1500 v5/6th Gen Core Processor Thermal Subsystem (rev 07)
--
01:00.0 VGA compatible controller: NVIDIA Corporation GM107GLM [Quadro M1000M] (rev a2)
   Subsystem: Dell GM107GLM [Quadro M1000M]
02:00.0 Network controller: Intel Corporation Wireless 8260 (rev 3a)
   Subsystem: Intel Corporation Wireless 8260


make.conf has VIDEO_CARDS="intel i965" and USE="glamor" set
/etc/X11/xorg.conf.d/20-modesetting.conf is
Code:

Section "Device"
  Identifier "Intel Graphics"
  Driver  "modesetting"
  Option  "AccelMethod" "glamor"
  Option  "DRI"  "3"
EndSection


cat /var/log/Xorg.0.log | grep EE
Code:
   (WW) warning, (EE) error, (NI) not implemented, (??) unknown.
[    19.223] (EE) modeset(0): Failed to initialize the DRI2 extension.



Xorg appears to be working fine, I'm in an X session, firefox opens and I don't really get any tearing, but I can't run any 3d accelerated programs.
