Xorg setup on multi GPU

Darryl · Feb 6, 2024

Hello!

I've given myself a deadline to get off the Micro$oft addiction. Hopefully before #12. That being said, I've always used FreeBSD in the server / non-graphical sense. But I'm sure running into some confusion when it comes to setting up a display. I don't know if I have the drivers setup correctly for DRM. If anyone can suggest an improvement on my specific setup, that would be appreciated. I'm using Dell XPS L702X where Intel HD Graphics 3000 is the primary display and Nvidia GeForce GT 555M is the secondary GPU on a Core i7-2860QM.

Some things I'm not clear about is if I need the Xorg() driver x11-drivers/xf86-video-intel or the i915kms driver graphics/drm-kmod or both.

The NVidia GPU is a quagmire to me, being able to choose from:

laptop firmware is not OEM, but its the only way to enable UEFI:

sysctl machdep.bootmethod:
machdep.bootmethod: UEFI

uname -a:

FreeBSD L702X 13.3-PRERELEASE FreeBSD 13.3-PRERELEASE stable/13-n257304-5c4e6fd30bbc GENERIC amd64

I only added the file 30-device.conf from Xorg -configure, without the bus id stuff I couldn't even get the display to show:

At this point, X loads to x11-wm/twm using x11/xdm. I can use www/chromium mixer(8) and backlight(8). However before I attempt a modern window manager and desktop environment, I'd like to see if I can resolve the NVidia error and make sure I'm using the intel driver properly. The rest of my mangled setup attempt is in the attached files:

Welcome to The FreeBSD Forums!

NVIDIA 390.xx is correct for the GeForce GT 555M according to both <https://www.nvidia.com/en-us/drivers/unix/legacy-gpu/> and <https://www.nvidia.com/Download/driverResults.aspx/196217/en-us/>. (There's sometimes a discrepancy. Not in this case.) DRM not possible with this driver.

(In my multi-GPU case: for simplicity, I chose to disable the Intel graphics, which doesn't help you.)

If KWin is in mind: be prepared for quirks (not showstoppers) with x11/nvidia-driver-390 when e.g. waking from sleep. Cross that bridge if/when you come to it.
