=== Nautilus connect to server by sftp ===

The Gnome file manager (AKA Nautilus) supports a multitude of server protocols, including ssh/sftp.
Allowing users to connect over FTP (especially SFTP) through the Gnome file manager is critical since a lot of Linux users rely on this protocol to access, download and upload files to servers and desktops running Linux over SSH.

Click on the “Other Locations” button to take the Nautilus and enter the server address: ''sftp:/ /lopeses.myqnapcloud.com:37132/''.
==== - Integrated Camera not available ====

  * The integrated webcam is not recognized, though an external one works fine.
<code bash>
jlopes@jclell3:~> sudo dmesg | grep -i "Camera"
jlopes@jclell3:~> 
jlopes@jclell3:~> sudo apt install v4l-utils
jlopes@jclell3:~> sudo v4l2-ctl --list-devices
Cannot open device /dev/video0, exiting.
jlopes@jclell3:~> sudo ls -l /dev/video*
ls: cannot access '/dev/video*': No such file or directory
</code>
  * The next step is to enter your BIOS/UEFI and make sure the webcam is enabled. You can enable and disable the webcam in the BIOS and it may have been disabled inadvertently. You can also consult the website to update your BIOS if necessary.
  * Install the [[https://wiki.ubuntu.com/Dell|IPU6/IPU6EP]] stack manually:
<code bash>
sudo add-apt-repository ppa:oem-solutions-group/intel-ipu6
sudo apt install linux-modules-ipu6-generic-hwe-22.04 linux-modules-ivsc-generic-hwe-22.04
sudo apt install libcamhal-ipu6ep0
sudo reboot 
</code>
<code bash>
jlopes@jclell3:~> sudo v4l2-ctl --list-devices
ipu6 (PCI:pci:pci0000:00):
	/dev/video1

ipu6 (pci:pci0000:00):
	/dev/media0

Virtual Camera (platform:v4l2loopback-000):
	/dev/video0
jlopes@jclell3:~> sudo ls -l /dev/video*
crw-rw----+ 1 root video 81, 0 jul 21 08:36 /dev/video0
crw-rw----+ 1 root video 81, 1 jul 21 08:36 /dev/video1
</code>
  * Add the video group to your user if this isn't done automatically
<code bash>
jlopes@jclell3:~> sudo adduser jlopes video # sudo usermod -a -G video $LOGNAME
jlopes@jclell3:~> cat /etc/group | grep video
video:x:44:jlopes
</code>
  * Workaround to make Cheese useable by disable v4l2 in pipewire # video for linux udev detection ([[https://askubuntu.com/questions/1473289/integrated-camera-not-working-on-dell-latitude-7440-and-7340-ubuntu-22-04|Askubuntu]])
<code bash>
sudo vi /usr/share/pipewire/media-session.d/media-session.conf
# comment that line starting with v4l2

shutdown now
</code>
  * Your integrated webcam should work on Zoom, Skype and OBS now, though not necessarily on Cheese
