Hi,
I never had success with cheese for a while now.
Try kamerka, it even detected my dashcam as a pc camera.
VokoscreenNG also can’t open my cam.
No luck. I ran this after it started:
ls -l /dev/video0
ls: cannot access '/dev/video0': No such file or directory
I unplugged the camera and plugged it back in:
ls -l /dev/video0
crw-rw----+ 1 root video 81, 0 Mar 11 21:19 /dev/video0
Kamerka keeps opening the Camera Settings dialog. No matter what app I try, /dev/video0 either doesn’t exist, or it disappears after I start any app. I guess I’ll have to use my Android tablet.
Hi
Check the other /dev/videoN in case it’s changed…
ls -l /dev/video*
Is it really /dev/video0?
I have two camera attached and I can open both simultaneously the two cam using kamerka.
The trick is just finding the video#
I replace the /dev/video#) with /dev/video1 or video0 depending of which camera I am using on the opened kamerka windows.
I just type the video# in the Device node under settings.
This is the only camera, there’s only /dev/video0, when it chooses to exist. My desktop PC has no other cameras.
Sometimes it changes the video# depending on which usb slot you inserted the usb chord.
Try ls -l using different video# til you find the right one
I tried Kamerka on my laptop. It works with the webcam /dev/video0, but it can’t see /dev/video1. That disappears when the app starts.
Here’s something that worked, more or less:
xawtv -c /dev/video0
This is xawtv-3.103, running on Linux/x86_64 (4.12.14-lp151.28.36-default)
xinerama 0: 1920x1080+0+0
If I resize the window, it goes black, and eventually closes. I have to unplug then plug back in to get it to work again. The window is tiny, though. I guess it’s 640x480? Maybe there’s a clue here, I don’t know. If I run xawtv without the -c /dev/video0, it doesn’t work.
The “fullscreen” option (right click on gui for menu) worked - that’s not bad! Better than nothing, anyway . . . . .
I tried inserting an image from xawtv here, but it didn’t work, here’s a link, perhaps it’ll work

To find available cameras
ls -ltrh /dev/video*
ls -ltrh /dev/video*
crw-rw----+ 1 root video 81, 0 Mar 12 10:47 /dev/video0
The issue is that /dev/video0 disappears when I start a camera app. I get this:
ls -ltrh /dev/video*
ls: cannot access '/dev/video*': No such file or directory
Hi
How is the device powered? Does it have the ability to have external power a Y USB power cable… If it’s disappearing it might just be a USB port power issue…
It’s powered by USB. The LEDs come on when plugged in, and stay on. It worked with
xawtv -c /dev/video0
but nothing else. No idea if a Y cable will work. On the Windows XP laptop it works fine, as well as the Android tablet. The problem seems to be only with Leap 15.1, on a laptop and on a desktop.
