Symptom:
Client on LC freezes, followed by eventual lockup of the operating system.
<br>
Problem:
Seen on Linux 16.04 systems with Server/Client versions 9.0 through 9.4 due to the OpenGL implementation.
<br>
Solution:
Option 1:
Disable GPU decoding then set VGA acceleration to ‘None’.
Option 2:
Install 9.4 or higher client
Install libegl1-mesa
sudo apt-get install libegl1-mesa
This should be included on systems with latest 16.04 image and Exacqpacq installed.
Note: There is a memory leak in Intel’s EGL drivers and the client may run out of memory after running for extended periods of time, but the OS will not lock up. This is fixed in the drivers included with 18.04.
Note: There may still be issues with Intel’s libva drivers for some CPU’s that crash the client, but the OS will not lock up. If you experience this, disable GPU decoding. You may leave VGA acceleration on.
Option 3:
Install exacqVision Client 9.6 or higher.
This client will be pre-installed with newer Intel libva drivers that will not crash. This new version will also be required for GPU decoding with Ubuntu 18.04.
Install libegl1-mesa
sudo apt-get install libegl1-mesa
Note: There is a memory leak in Intel’s EGL drivers and the client may run out of memory after running for extended periods of time, but the OS will not lock up. This is fixed in the drivers included with 18.04.
