I already tried different solutions mentioned here #228 with no success.
I had this problem since older versions o the kernel and other versions of Ubuntu

EDIT

Just to add more information about what i have tried, before open this issue
![image](https://github.com/intel/ipu6-drivers/assets/30013138/43123126-e0cc-47dc-922b-a767670af155)

- Fresh install, with `IPU6 driver from intel-ipu6-dkms` by himself with out install anything more.
- Fresh install, with `IPU6 driver from intel-ipu6-dkms` by himself making some changes on the file location, and installing some packages trying something.
- Fresh install, remove `IPU6 driver from intel-ipu6-dkms` and install `IPU6 from libcamhal0`. Tried using the steps of this repository o Readme and also using the ppa.
- Fresh install, use `IPU6 from libcamhal0` without remove `IPU6 driver from intel-ipu6-dkms`.

Any case always get the same error.

Yes, I know and understand my system is not "officially" supported for Ubuntu, but never was a problem until now.

Hi,

Same as https://github.com/intel/ipu6-drivers/issues/237 for Samsung, we have observed that even those designs with IPU6 Camera but has no Ubuntu cert granted. Hence the integration should be involved with BIOS configuration (I have seen in some cases BIOS config is wrong; but the camera still works in Windows. Suspects there are hacks in Windows driver), upstream kernel driver implementation, and few xml files required to be modified in user space. PC vendor would have to step in to make the camera work both on Windows and Linux.

Not sure Acer customer service will give you the response, but there is no easy way to obtain an installation package on your Acer device. Thanks.
