ThinOS 2311(9.4.4123) / Citrix / Zoom Citrix update and screens go black

We have Thin Clients 5070 & Optiplex 3000 thin clients.

Issue after updating the two different thin Clients we are having random thin clients screens going black and either you wait a couple of minutes and it comes back or you reboot the thin client. The citrix session is still running. Any thoughts?

The black out of the monitor will happen more then once for the users

Testing out the latest upgrade to 

BIOS

5070 > 1.26

3000 > 1.13.2

ThinOS2311_944123

Citrix Workspace 23.9.0.24.4

Zoom_Citrix_5.16.0.24280.1

I am also experiencing the same issue. I have a handful of Wyse 5070 with Bios version 1.20, ThinOS 9.4.3087, and Citrix Workspace 23.8.0.39.1.

I am now testing to see if I can replicate the issue with Bios 1.24, ThinOS 9.4.4123, and Citrix Workspace 23.9.0.24.11. We have yet to narrow down what is the root cause.

After updating a number of dell Wyse 3040 and 5070 we are experiencing the same issue on several devices.

wyse 3040 => BIOS 1.2.5 and wyse 507 => BIOS 1.26.0

Dell ThinOS 2311 (9.4.4123) with Citrix Workspace 23.9.0.24.4 and WVD 2.3.2266

Currently the only option seems to downgrade to a previous working version.

Screen goes black several times per day, session is still running in the background. A reboot is needed after which session can be reconnected.

Has anyone had any luck with the updated versions?

We are also seeing similar on a couple of test terminals with 2311, although having updated it to 2402 a couple of days ago, I haven't seen it since.  We are having other issues though (also introduced a couple of month ago), like headsets not being detected if they are plugged in after the terminal has established a session to Citrix.

So I can't really roll out anything more widely - solve one issue and introduce another.  Most of our terminals are running year-old firmware at this point because every newer version just brings more problems.  :(

Trying the below on the 5070s and 3000 and so far haven't had any blanking of screens. What I am having is issues installing the Citrix_Zoom with this Firmware and ThinOS. Citrix zoom installed on my test 3000 but on all other 3000 and 5070s it just fails on the install with no real reason.

bios-5070_1.26.0.pkg-V1.26.0

bios-Op3000TC_1.15.0.pkg-V1.15.0

ThinOS_2402_9.5.1079.pkg-V9.5.1079

Citrix_Workspace_App_23.11.0.82.6.pkg-V23.11.0.82.6

Zoom_Citrix_5.16.0.24280.1.pkg-V5.16.0.24280.1

Upgrade to (2402)9.5 seems to fix the reboots.

@Tuco2005​  Zoom seems to be Build into the firmware like Teams on this newer Firmware 9.5. I did see a Universal Zoom that we are looking into in the list of install apps.

Hello everyone,

We are experiencing the same issue with Dell Wyse 3040 thin clients running ThinOS 2402 (9.5.1079).

The thin clients freeze, the mouse becomes unresponsive, the screen turns black, and then an automatic restart occurs.

I cannot identify the problem, and it is becoming very inconvenient for users as this malfunction happens several times a day.

Does anyone have a solution or a lead on the cause of the problem?
