Feedback, webcam software not working

[avj]

Whenever a new release comes out I usually do a fresh install after making a backup of my personal data. It usually takes about 2 or three days to get everything tweaked back to the way I like it. I had hoped to find some instructions, but instead found that it, as far as I know, is not even an option to be downloaded and installed from the usual repository for lite kernels. It is all good now though, just have a few online accounts left to set back up and everything will be back to normal.

That's cool. 

Other than removing older kernels using Lite Tweaks, I haven't jacked with kernel stuff yet.  But I thought if a kernel wasn't deleted, you could choose the advanced/recovery mode option in GRUB and boot from a different kernel that way.

[avj]

After searching the forum several times looking for instructions for rolling back the kernel to a previous version, I opted to just install LL 2.6 and upgrade from there.  Good news, everything is working as expected.

[torreydale]

Maybe you should downgrade to the 3.13 kernel or go back to LL 2.6 and do an in place upgrade to LL 2.8, keeping the 3.13 kernel in the process.

I tried Cheese, but it was a little too resource hungry and started lagging out my computer.  I eventually had to kill the app from the task manager. I was able to confirm that this isn't a hardware issue by using a system back live DVD of my former LL 2.6 system using guvcview, and was able to take photos, and make a video.  It is looking more and more like I may have to go the upgrade route, unless someone has other suggestions.

Have you tried Cheese? I've had guvcview not work, then Cheese work on the same pc. Strange, I know.

Thanks firenice03, I was hoping to avoid having to do that but it looks like it may be the only alternative.

avj..

If it helps...
Mine is working.. 2.6 upgraded to 2.8..
Kernel: Linux 3.13.0-24-generic

Let me know if anyone needs any command outputs if it would help...

[avj]

According to Lite Control Center I am running kernel 3.19.0-33-generic.

I did find a bug report on launchpad that appears to be the same issue from the link that you posted.

O.K,
It appears to be recognised and there,
I think the first few unknowns, failed, and jack are all Audio items, so should not affect video.
Not sure what else to suggest... Maybe somebody else will come along with suggestions.

What kernel are you using, I found this:

To Wirezfree, The software is guvcview. When I run the "dmesg | grep uvcvideo" in a terminal I get the following.

Hi,

From some early rough notes, I think my daughters laptop..??:

Code: [Select]

dmesg | grep uvcvideo
If you see "failed to initialise -5 error"
Try:

Code: [Select]

sudo rmmod uvcvideothen

Code: [Select]

sudo modprobe uvcvideo
Then see if LL Webcam S/W(guvcview?) works

@avj
I think we have very similar netbooks
Mines a Dell Inspiron Mini - Atom N270 1.6Ghz - 1GB - Intel Mobile 945GSE Express

I'll check mine this evening, can't recall if I installed the webcam since I upgraded to 2.8..

If anything good to know if issue replicates..

[avj]

     The webcam software in Lite Software is not working on this netbook. I am running LL 2.8 32 bit. It worked well in 2.6, but now it doesn't show anything from the camera, just a black window. I tried reinstalling the software, but that did nothing. I used lsusb and my camera show up as:  Bus 001 Device 004: ID 0c45:62c0 Microdia Sonix USB 2.0 Camera. I have uninstalled the software, and installed camorama in its place and everything works fine. Just thought the development team should be aware.

A little more info, the camorama software only supports still captures not video.
