Acer Aspire one ZG8 webcam not working

[snoopyonline78]

Dear all,

I installed now Linux mint on my Aspireone ZG8, but the integrated webcam dosen’t work. The uvcvideo error message come a lot of times, and don’t let me write commands in the command line. How can i install the needed driver?

Regards

[HAWR]

Hello snoopyonline78,

most of the webcams today (integrated and external) have the UVC standard and in Linux the uvcvideo driver is the driver for them. There is no alternaitive driver. Please post the outputs of the following terminal commands (see point 5 of how to get help to display it in a good readability)

Code: Select all

inxi -Fxxxrz && lsusb

Code: Select all

dmesg | egrep 'uvc|video|cam'

The dmesg result was empty

[HAWR]

The dmesg result was empty

Then it seems, that the uvcvideo driver isn't loaded. What happens, when you load it?

Code: Select all

sudo modprobe uvcvideo

[snoopyonline78]

I added it to the blacklist, to prevent this a screen full of error messages

[HAWR]

But you need that driver for the webcam. Please remove the blacklist entry and reboot. Then you can post the results of the dmesg command:

Code: Select all

dmesg | egrep 'uvc|video|cam'

And if possible, post the error messages from your screen.

Error:

[HAWR]

You are using LM 19.3 and the 5.4 kernel. Have you tried it with a 4.15 kernel, which is the default LTS (long term supported) kernel for your LM version? Maybe this fits better to your older hardware.

[snoopyonline78]

Thanks, how can i do it?

[HAWR]

Open the Update Manager > View > Linux kernels and choose the 4.15 tab on the left side. If there is no kernel installed, install the latest one. If there is one installed, you only have to reboot and in the Grub menu to choose the Advanced Options. There you find the possibility to boot with the 4.15 kernel. If you don't see the Grub menu during start, press immediatly Esc a few times after the Acer logo is gone. If it works with the 4.15 kernel, please remove all 5.4 kernels in the Update Manager > View > Linux kernels.

Error persists

[HAWR]

I've just searched a little bit and found several sites with that error without a real solution. So I'm not hopeful, we can solve it. Have you installed the program Cheese from the Software Manager? Please try the following up to 3-4 times and after each try, see what happens:

Code: Select all

sudo modprobe -r uvcvideo
sudo modprobe uvcvideo

[snoopyonline78]

ZG8-AO531h:~$ sudo modprobe -r uvcvideo

[HAWR]

The Glib warnings because of Cheese can be ignored, they are because it's a graphical program, which you can also choose from the Menu. You can try it with Guvcview from the Software Manager. Sometimes Cheese won't work with webcams.

[snoopyonline78]

Guvcview - > no video device found

[HAWR]

You should test a live-system of your LM 19.3 XFCE 32bit, if the webcam runs normal on it. Your webcam is listed under the UVC webcams as fully supported http://www.ideasonboard.org/uvc/

Here is the link to the download: https://www.linuxmint.com/edition.php?id=278

Make a bootable device and boot with it into the live system. You could install Cheese and Guvcview for testing and use an online test with the browser: https://webcamtests.com

Regards to all for your help! I learnt much from you!

It's really incredible. how can a compatible standard device make such problem. For a newbie (Mac user) unbelievable. I hope to understand it soon

Tanks a lot!!!!!
