Dell ThinOS 2211, 2208, and 2205 Release Notes
Horizon Blast Updates
- HD Pro Webcam C920 and Logitech BCC950 Conference Camera do not work on Webex Teams VDI video call. The issue also occurs in Horizon Linux Clients.
- Wyse 3040 Thin Client uses H264 software decoder and MMR/H264/HEVC is not supported on Horizon Client 2206 with ThinOS 2208.
Limitations and Known Issues
- Camera names are not displayed correctly in Horizon SFB due to a VMware limitation.
- Blast session may not launch due to a compatibility issue with the Zoom Horizon package. The workaround for the issue is to go to Systems Tools > Packages and delete the Zoom Horizon package.
- HEVC is not supported in this release.
- The following limitations are applicable only on OptiPlex 5400 All-in-One:
- ThinOS may reboot unexpectedly when disconnecting the blast session that has a redirected camera.
- If the USB port on the side is used for connecting to a camera, some cameras do not work during Microsoft Teams or Cisco JVDI calls. This is a hardware limitation. Connect the camera to a rear USB port for the camera to function during Microsoft Teams or Cisco JVDI calls.
