LC Client or Operating System freezing

Description 

LC’s with the ASRock H110M-ITX motherboard may show the video images freezing, followed by a freeze of the Operating System.

Workaround 1

  • Set VGA acceleration to none
  • Note that this also means GPU decoding is disabled

Workaround 2

  • Install 9.4 or higher client
  • Install libegl1-mesa
    • sudo apt-get install libegl1-mesa
    • This should already be included on systems with the latest 16.04 image with Exacqpacq installed.
  • Note that 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. However, the system will not lock up. This is fixed in the Intel drivers included with 18.04.
  • Note that there may still be issues with Intel’s libva drivers for some CPU’s that may crash the client. However, the system will not lock up. If you experience this disable GPU decoding (VGA acceleration can remain on).

Workaround 3 (future release)

  • Install 9.6 or higher client
    • 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 on 18.04.
  • Install libegl1-mesa
    • sudo apt-get install libegl1-mesa
  • Note that 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. However, the system will not lock up. This is fixed in the Intel drivers included with 18.04.
