Webcam not working with Cheese

Hi all,

I'm trying to get a webcam working on Q4OS; the webcam is seen by the system:

franco@q4os-desktop:~$ lsusb
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 006: ID 0bda:b812 Realtek Semiconductor Corp. RTL88x2bu [AC1200 Techkey]
Bus 002 Device 008: ID 093a:262c Pixart Imaging, Inc.
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

If I open Cheese, the webcam is seen as "USB Camera (093A:262c)" but I get a message saying that there was an error playing the video from the webcam.

Searching within the various forums, I've found a similar situation, which concerned "module" called gspca_pac7311

I would like to have input regarding the hint get on that forum or any other hint (drivers/other) to get the webcam working.
Thanks in advance

Hi all,
With some difficulties, being very new to the Linux environment, I did some checks and discovered that, within the folder /usr/lib/modules/6.1.0-10-686-pae/kernel/drivers/media/usb/ there are a lot of "gspca" objects, including the one I was looking for and, in theory, should be useful, namely gspa_pac7311.ko

My questions at this point are:
- how can I "load" this object to test that it works ?
- if the test will be positive, how to load this object every time the machine starts ?
- if the test will be negative, what actions and commands should be used to do further tests ?

Thanks in advance

You can load kernel modules in terminal this way:
$ sudo modprobe <module_name>
for your case:
$ sudo modprobe gspa_pac7311

Hi there,

Thanks for the info.

I've load this module with the above command.
The error message disappeared, but I have a black screen.

Hi! Nice job digging into the modules. To test the driver, try running sudo modprobe gspca_pac7311. If it works, you can load it at boot by adding the module name to /etc/modules. If it fails, check dmesg for errors to help with troubleshooting. Good luck!
