Zero Client Crashing with vGPU and two monitors

[respodu]

Whenever we try to connect to a vGPU enabled pool with two monitors the Zero Client (Wyse P25) crashes and reboots. If the pool is set to refresh then you will never be able to login.

I set the pool to not refresh and I'm able to login. The issue is specific to two monitors if i use only one the connection works properly on the first attempt.

Hi Respodu,

we got the same issue on our environment. We have the effect ,when we trying log on from a zeroclient with dual-Display to a vGPU-enabled Pool, the Zero Client crashes. The Loggon-Process to the VM goes on in the Background and so we are able to log on  after couple of time.

Have you found a solution for your Problem?

ZeroClient t310 Firmware 4.7.1 or 4.8.0

Nvidia k1 grid_K120Q

Esxi 6.0.0

View 6.1.1

[respodu]

I've been unable to solve this issue.

[klibo87]

We have the same Issue in our environment!

vGPU, K1, Horizon View 6.1.1 and vSphere 6.0. Teradici FW 4.8

[respodu]

I've opened a support case with VMware.

Let see what they come up with but by judging from my previous few tickets I've opened on vSphere/View/vRops.... its a bug...

[Linjo]

I remember a similar case I had, the solution was to upgrade the firmware on the GPU. Tried that?

(You probably have to open a case with the vendor (HP, DELL, IBM) to get the latest firmware.

// Linjo

[respodu]

it was a problem with the zero client if you change the default display topology it causes the issue.

Hi respodu

Is the problem solved? I met the same problem!
