Q Series Units Using KVM Switch Showing No Display on Boot Up and when switching between units.

This is for a specific customer that was reporting issues with Q series units using a KMV Startech Switch-Model SV431USB.
The customer experiences NO DISPLAY on the monitor on boot. They also exhibit no display when switching the source at the switch from a windows based unit back to the Q Series.
Tickets: 22721 and 23035.

Testing results:
14.04 <== won’t remediate – end users will have to re-image with 18.04 key.
16.04 <== won’t remediate – end users will have to re-image with 18.04 key.
2019-03 = first 18.04 with golden image:
* Note that you’ll get a warning “old exacqdeploy package post-removal script sub process returned error exit 1”, but this is ok. Ignore it. This warning unfortunately cannot be suppressed.
2019-12 = first 18.04 with packer image:
Verified at version 19.06.4 and newer.
Verified 20.09.1
2021-03 = final 18.04-based key.
Verified 21.03.5.
If they are on a version older than 19.06.4 they will need to update to at least 19.06.4 or update to the latest release. Do not use this if they are on Ubuntu 14.06 or 16.04.



The URL below will allow you to download the .DEB file. That can be transferred to the local NVR and ran on Ubuntu 18.04 servers with at least 19.06.4 Server installed.

https://crm.exacq.com/release/Support/exacqdeploy_21.06.116.0_all.deb

  1. Download the file.
    2.) You will have to put the file on the desktop of the NVR and then open terminal and run the following 2 commands.
    cd /home/admin/Desktop (press enter)
    sudo dpkg -i exacqdeploy_21.06.116.0_all.deb (press enter)
  2. Restart the machine.

Primary DNS Shown as 0.0.0.0 on Linux Server Configured for DHCP

Symptom:

On a Linux system configured for DHCP the exacqVision Client network settings page displays 0.0.0.0 as the primary DNS. 

<br>

Problem:

This is may be cosmetic, the actual primary DNS for the server should be correct IF a primary DNS is assigned from the DHCP server. 

<br>

Solution:

Update the exacqVision Server to version 9.2 or higher.

3rd Party Linux servers and recording to a NAS?

This process is not officially supported or endorsed by Exacq. Use at your own risk.

When the exacqVision Server software starts, it will look into the following location for storage purposes:

/mnt/edvr/*

NOTE – * – This is typically a number on systems built by Exacq.

Any volume that is mounted into the /mnt/edvr location will be available for storage.

NAS Setup

Here is an example setup using FreeNAS:

  1. In the BIOS Setup, set the hardware RAID (Striped with Parity).
  2. Set up FreeNAS on the computer server hard drive.
  3. Assign the system an IP Address.
  4. Set up NFS Share using FreeNAS.

Linux NVR

  1. If needed, log off as restricted user and log back in as an admin user.
  2. Launch the Terminal application.
  3. Create storage directoryfor your NAS location by typing:
    sudo mkdir /mnt/edvr/2
    NOTE – Ensure that there is not already a “2” directory – if so, pick a higher number
  4. Edit the /etc/fstab file to include the mounting of the NAS at startup by adding line
    %servername%:%/mnt/vce-nas/% /mnt/edvr/2 nfs defaults 0 0
    NOTE: %servername% is your full server name or IP address, and %/mnt/vce-nas/% is your NAS server mount point.
  5. Restart the exacqVision NVR Server to activate NAS Mount.
    sudo service edvrserver restart
  6. In the exacqVision Client, use the Storage tab to enable recording to /mnt/edvr/2.
  7. Verify that recordings are being stored on new mount point.
