On Linux Mint permission (group) problems

[David]

Hi patjak,
I've installed facetimehd module and loaded it generate rightly the device /dev/video0.

This device has the following permission:

ls -l /dev/video*
crw-rw----+ 1 root video 81, 0 set 2 23:32 /dev/video0

But the normal user are not member of "video" group.

With the following command we can add the user to the "video" group and solve the issue:

'sudo usermod -a -G video $LOGNAME'

I still have to check the procedure physically on the computer (an AirBook of 2015) if it solves I let you know

I think should be fine adding this scenario on your documentation.

Thanks!

I've write simple (and tested on Linux Mint 20.2 ) script, for creating and installing the module and build the dkms module ->

#!/bin/bash

sudo apt install linux-headers-$(uname -r) git kmod libssl-dev xz-utils curl cpio
cd /tmp
mkdir facetimehd
cd facetimehd/
git clone https://github.com/patjak/facetimehd-firmware.git
cd facetimehd-firmware
make
sudo make install
cd ../
git clone https://github.com/patjak/bcwc_pcie.git
cd bcwc_pcie
make
sudo make install
sudo depmod
sudo modprobe facetimehd
# rm -Rf /tmp/facetimehd/
# genero il pacchetto DKMS...
echo -e "GENERAZIONE \e[92mDEL PACCHETTO DKMS IN CORSO..."
sudo apt-get install build-essential
sudo apt install -y debhelper dkms
sudo mkdir /usr/src/facetimehd-0.1
sudo dpkg -r bcwc-pcie
sudo cp -r * /usr/src/facetimehd-0.1/
cd /usr/src/facetimehd-0.1/
sudo rm backup-*tgz bcwc-pcie_*deb
sudo make clean
sudo dkms add -m facetimehd -v 0.1
sudo dkms build -m facetimehd -v 0.1
sudo dkms mkdsc -m facetimehd -v 0.1 --source-only
sudo dkms mkdeb -m facetimehd -v 0.1 --source-only
sudo cp /var/lib/dkms/facetimehd/0.1/deb/facetimehd-dkms_0.1_all.deb /root/
sudo rm -r /var/lib/dkms/facetimehd/
sudo dpkg -i /root/facetimehd-dkms_0.1_all.deb
echo -e "PROCEDURA COMPLETATA \e[92mRIAVVIARE IL COMPUTER!"

Hi, everyone can edit the wiki so feel free to add the information if needed. This particular issue is distro specific so try placing it somewhere where it makes sense. Thanks
