Surface Pro 6 Front Camera Not Working (Green) and Back Camera Upside Down
balintbarna opened this issue · comments
Hi everyone
I have a Surface Pro 6 running NixOS, including the microsoft/surface/surface-pro-intel nixos-hardware config.
When I open the gnome camera app I can switch between the back and the front camera. The front camera image is fully completely green, the back camera image works but is upside down and not amazing quality-wise.
Is there anything I can try to get that front camera working and maybe even rotate the back camera the right side up?

🤷
Did you use the Gnome camera app when trying your camera? I had that issue too after just installing the kernel with patches. What you need to do is:
- Install a custom
libcamerathat follows the instruction on the linux-surface page:
This one works for me: https://github.com/damianoognissanti/libcamera-surface
You can install it by putting the file in your configuration.nix-folder and import it with "./libcamera.nix" (don't forget to git add the file if you use git and flakes) right under the import of hardware-configuration.nix, that is:
imports =
[
# Include the results of the hardware scan.
./hardware-configuration.nix
# Add libcamera (necessary for Surface Book camera to work)
./libcamera.nix
];
-
Install kernel modules for
v4l2loopback, check this:

You will probably need to change the command a bit, for example my front camera is named_SB_.PCI0.I2C2.CAMF. The name is found by runningcam -lafter installing libcamera. -
Run the
gst-launch-1.0command found in step 2 to launch the camera (after a reboot). You also need to install gstreamer plugins for this. I installed
gst_all_1.gstreamer
gst_all_1.gst-plugins-base
gst_all_1.gst-plugins-good
While the command is running the camera should work.
Btw, this worked for Cheese, but the new Gnome camera app doesn't seem to find that camera, but Zoom does, so you need some camera software where you can select the video device (i.e. /dev/video0 or what you chose when running the command in step 2).
@damianoognissanti Thank you for the reply. It still doesn't work. What happens now and also before, is that when I open the camera app, it activates the white led by the front camera, but the image is just a green blob. If I switch cameras, it activates the little white led by the back camera and I can actually see some image from that camera, but it is upside down and very dark.
My setup:
let
nixos_hardware = fetchGit {
name = "nixos-hardware-2024-03-03";
url = "https://github.com/NixOS/nixos-hardware/";
rev = "59e37017b9ed31dee303dbbd4531c594df95cfbc";
submodules = true;
};
libcamera_surface = fetchGit {
name = "libcamera-surface-0.2.0";
url = "https://github.com/damianoognissanti/libcamera-surface/";
rev = "7268e5ed4389d8b2390321dd4f47da200bd75fde";
submodules = true;
};
...
in {
imports = [
/etc/nixos/hardware-configuration.nix
"${nixos_hardware}/microsoft/surface/surface-pro-intel/"
"${libcamera_surface}/libcamera.nix"
...
];
...
}
Do any of these show something useful?

As a side note, the camera is not the only issue, the power and volume buttons worked a few times but most of the time they just don't. And about 1/3 of the times when shutting down iptsd gets stuck and I have to long-press the power button to power it down. sudo modprobe -r soc_button_array; sudo modprobe soc_button_array fixes the buttons.
gst-launch-1.0 _SB_.PCI0.I2C2.CAMF
This might be the problem, you don't run the command I told you about. You must have a backslash in the camera name (the name is "\_SB_.PCI0.I2C2.CAMF" as you can see from the cam -l command), and you must escape both the backslash as well as the underscore. What happens when you run the following?
gst-launch-1.0 libcamerasrc camera-name='\\\_SB_.PCI0.I2C2.CAMF' ! videoconvert ! v4l2sink device=/dev/video0
Thank you, that works, sort of. The image is (not) mirrored, so when I move left my image moves right which is pretty disorienting. Do you know if there's a flag or a simple way to mirror it? In addition the quality is pretty low, seems like the white balance is off and either the resolution is low or it looks out of focus. Anything to do about that? And is there a way to avoid having to manually run the terminal command each time? I guess I could create a service but then the camera will be always on...
I have a script called startcamera that runs the above command. That command can either be run before you start some camera application by changing the .desktop file, or can be bound to a keybinding. I start it in a terminal though, since I don't use the camera that frequently and it feels like I'm "in control" that way (but that's just a feeling).
If I google gstreamer flip video the very first search result is:
https://gstreamer.freedesktop.org/documentation/videofilter/videoflip.html
which can flip the image in whatever way you want
Video-flip-method
The different flip methods.
Members
none (0) – Identity (no rotation)
clockwise (1) – Rotate clockwise 90 degrees
rotate-180 (2) – Rotate 180 degrees
counterclockwise (3) – Rotate counter-clockwise 90 degrees
horizontal-flip (4) – Flip horizontally
vertical-flip (5) – Flip vertically
upper-left-diagonal (6) – Flip across upper left/lower right diagonal
upper-right-diagonal (7) – Flip across upper right/lower left diagonal
automatic (8) – Select flip method based on image-orientation tag
Try to check the manual for the other things you wonder too.
Thank you, that's very helpful. Of course it would be nice if we could make it work "out of the box" using the nix configuration, but this will work for now.
