Random BlackScreens - vGPU VMware Horizon

Hi all,

we have random, rarely black screens in our vdi environment. Only a reboot of the affected VM will help to fix it.
Nvidia Support told us to upgrade vGPU driver from 13.2 to latest 13.4.
We using Nvidia M10 on VMware Horizon with Windows 10 - 20H2 and grid_m10-1b profile and VMware ESX 7.0 U3d

After upgrading we can still see a lot of these events in the nvidia esx logs

Does anybody know if it normal?

Hi,
sounds like a known issue. NVES should be aware of this. Upgrading to 13.4 won’t fix it as the root cause is still under investigation. Please contact NVES once again to add your case to the list of affected customers.

Thanks Simon for this info.

NVES told me that this is fixed in 13.4.
But I can’t find any information in the relase notes about this issue. So why is there no public information about it?

I will talk again with NVES.

Just send me your case ID with PM. Will route your case in the right direction. I’m not aware that this is fixed in 13.4.

Hi Simon,

did you get my PM? Any news regard this issue?
