Not working Thinkpad E15 Gen2 (AMD)
I've got the new model Thinkpad E15 Gen 2 here, and it doesn't work. There was some message during installation, that unfortunately scrolled off the screen about not being able to recognise a video device and that "some manual configuration may be required". When I run sudo howdy add I get:
Camera path is not configured correctly, please edit the 'device_path' config value.
Exception ignored in: <function VideoCapture.__del__ at 0x7f26c0c3c550>
Traceback (most recent call last):
File "/usr/lib/security/howdy/recorders/video_capture.py", line 55, in __del__
self.internal.release()
AttributeError: 'VideoCapture' object has no attribute 'internal'
The output of lsusb for what I presume is the video device is:

I changed howdy config to add what I presume ought to be the right device:
device_path = /dev/v4l/by-path/pci-0000:05:00.3-usb-0:3:1.0-video-index0
However, no real success. Howdy test does this:
Opening a window with a test feed
Press ctrl+C in this terminal to quit
Click on the image to enable or disable slow mode
Traceback (most recent call last):
File "/usr/local/bin/howdy", line 109, in <module>
import cli.test
File "/usr/lib/security/howdy/cli/test.py", line 66, in <module>
cv2.setMouseCallback("Howdy Test", mouse)
cv2.error: OpenCV(4.3.0) /io/opencv/modules/highgui/src/window_QT.cpp:717: error: (-27:Null pointer) NULL window handler in function 'cvSetMouseCallback'
Looks like your video device can't be read correctly, can you view your camera feed in a program like cheese?
Then you're using the normal webcam, try switching to the IR camera in the options
How would I switch to the IR camera? I tried all the other device paths in that directory of devices, but no cigar.
Also oddly, "howdy add" seems to now not complain when I attempt to use it. But "howdy test" comes up with a flat grey window and spews this out continually on the console:
X Error: BadDrawable (invalid Pixmap or Window parameter) 9 Major opcode: 62 (X_CopyArea) Resource id: 0x520000f
Mmmm, now running it again, no changes to the config, it puts out the error I reported up the top.
I tried the QT_X11_NO_MITSHM=1 thing, and as far as I can tell it has no effect on behavior, HOWEVER, with all the playing around I found howdy test actually comes up with a window about 1 in 5 times. None of the documentation says what I'm supposed to see at this point, but it looks like it's working. I see myself in black and white, I see a red circle around my face, I see green numbers in the lower left.
However, while it works about 1 in 5 times, the other times it crashes with the error above about /window_QT.cpp:717. As far as I can tell QT_X11_NO_MITSHM=1 has no effect on its frequency of success. I also tried the force_mpeg which seems to have no effect, and I tried upping the certainty to 5
I also often get this when I click on the test image:
Traceback (most recent call last):
File "/usr/local/bin/howdy", line 109, in <module>
import cli.test
File "/usr/lib/security/howdy/cli/test.py", line 186, in <module>
time.sleep(.5 - frame_time)
ValueError: sleep length must be non-negative
Having said all that, it does actually seem to be working for me now to sudo and to login. I'm presuming upping the certainty number made the difference.
I stand corrected, the QT_X11_NO_MITSHM=1 is necessary for it to work. But it doesn't stop howdy test crashing 4 out of 5 times.
So I've got the E14 Gen2 with the same webcam and using /dev/video0 lets howdy use the normal webcam and /dev/video2 for the IR one. However, there is still no way of turning the IR blaster on (only on chicony based cams afaik)...
If I use /dev/video2 for howdy test, the quality is awful. But if I use /dev/v4l/by-path/pci-0000:05:00.3-usb-0:3:1.0-video-index0 the quality decent. What this means, I don't know.

isn't this the normal rgb cam?
Playing around in Windows, a reddish light comes on during face detection, and I've never seen that under Linux, so.... it doesn't seem like I've stumbled across anything to make the IR work.

I have this exact issue as well, on the Lenovo Slim 7. When using the IR-camera (/dev/video2) the IR-leds are not flashing. I wonder if there is any simple fix to this issue.

I'm on Thinkpad E14 gen2 and I have the chicony one and so far I wasn't able to get the IR blaster working.. if there's a way, could you please point me in it's direction? Thanks
@ONDRA5 ... I couldn't get IR working, but I could get howdy working without it.
added device path in config: device_path = /dev/v4l/by-path/pci-0000:04:00.3-usb-0:3:1.0-video-index0 howdy test shows a great gray image!

The right camera to use on Thinkpad E15 Gen2 is /dev/video2, which is the IR camera. When you open the camera you should see a black and white image. For the IR camera to work, you need to enable the IR emmiter, see #269, TL;DR you need to install https://github.com/EmixamPP/linux-enable-ir-emitter
