Problem with displaying a dialog box or a drop-down list

In some cases, when you change the configuration of objects for which you need to set a location or select a value from the drop-down list, when you click on the button to select a location or list value, they do not open.

Note

In fact, the location selection window or a drop-down list are opened outside the interface shell, and therefore are not visible to the user.

To resolve this problem, select a different desktop environment and restart Axxon Next. For example, use Gnome Classic instead of Gnome for Debian 11.

Specifics of detection tools operation on NVIDIA GPUs in Linux OS

By default, the Nouveau driver can be installed in Linux OS. This driver does not guarantee stable operation when using NVIDIA graphics cards for decoding Axxon Next detection tools (see Configuring detection tools).

To resolve the problem, you need to install the current graphics card driver from the official NVIDIA website and run the command in the terminal:

nvidia-smi

If the operating system uses the installed driver to work, the driver version will be displayed. Otherwise, if the current driver is installed, but the operating system uses the Nouveau driver, you need to add it to the exclusions list and restart the computer. Below is an example of Ubuntu commands to add the Nouveau driver to the exclusion list:

sudo bash -c "echo blacklist nouveau > /etc/modprobe.d/blacklist-nvidia-nouveau.conf"
sudo bash -c "echo options nouveau modeset=0 >> /etc/modprobe.d/blacklist-nvidia-nouveau.conf"

After restarting, the operating system will use the installed NVIDIA driver.

Problem with memory dump in Astra Linux SE environment

Sometimes, when Axxon Next modules are shut down incorrectly in Astra Linux SE environment, memory dumps are generated incorrectly and cannot be decrypted. To solve the problem, it is necessary to disable the blocking of the Ptrace service in Astra Linux SE environment using one of the following methods:

  • using fly-admin-smc graphical tool: go to Control Panel → Security → Security Policy → Security Settings → Kernel Options.

  • using console mode: run the following command:

    astra-ptrace-lock disable

To check the status of the Ptrace service, run the following command:

systemctl is-disabled astra-ptrace-lock

The following messages may be received in response to the command:

  • enabled—Ptrace service is enabled;
  • disabled—Ptrace service is disabled;
  • Failed to get unit file state—Ptrace service is not activated.
  • No labels
