Issue with omnissa Horizon client thinstation-ng

[trezel]

Hi,

I'm trying to build an omnissa thin client, and I noticed some bugs in thinstation-ng :

First, omnissa autostart doesn't work. The message (in logs) tells options fullscreen and allmonitors can't be used together.
I couldn't find any allmonitors option in conf files, and didn't find the way to disable it. Disabling fullscreen option in SESSION options makes the omnissa autostart to work, though (and in fullscreen mode !).

Second, during building, I saw an error message :

Configuration file /etc/systemd/system/horizon-USBArbitrator.service is marked executable. Please remove executable permission bits. Proceeding anyway.

I tried a chmod -x on this file in chroot, before a new build, but error message still present. It seems the executable bit is added during build process.
The service can't launch (error message during client start).

Have a nice day

E.T.

trezel,
on earlier versions I changed after the first build process in vmview/etc...
After the next build it was in the iso .
How large is your image with omnissa, I have 700MB, this does not start as ISO under iPXE.
Don gave same hints, I need to check this and your good described way to boot with iPXE.
But in general he imag is much larger, before I was under 500MB

Hi,

A few days later....
Omnissa client finally works.

First, the "fullscreen thing" : You can disable fullscreen option in SESSION# options, and it launches, as I told in the first post.
I found the all monitors option, in build/packages/horizon/etc/cmd/horizon.global
This file is a place where you can add more launch options, if you want.

Second : the error message about "horizon-USBArbitrator.service is marked executable" doesn't prevent omnissa client to work (USB works).

Last : I couldn't launch a VM, without disabling H246, av1... in omnissa client's preferences menu. Even with nouveau driver installed. We need nvidia drivers for this to work, and since nvidia driver installation is for now impossible in ts-ng,..
It doesn't seem clean to me to oblige users to make such things everytime they want to connect.
I found the solution for this too (leaving only blast) :

• Create a file named horizon-mandatory-config with these parameters :

view.allowBlastProxy = 'FALSE'
view.allowBlastToast = 'TRUE'
view.enableAV1 = 'FALSE'
view.enableBlastCodec = 'TRUE'
view.enableH264 = 'FALSE'
view.enableH264YUV444 = 'FALSE'
view.enableHEVC = 'FALSE'
view.enableHEVCYUV444 = 'FALSE'

• Put it in : build/packages/horizon/etc/omnissa/horizon-mandatory-config
  It will be present on clients, and configure the right options for users.

If it can help someone...
Regards

I wonder if your just missing codecs, or if you really need Nvidia proprietary for this to work.

[trezel]

I'm not sure neither. Maybe some codecs, you're right.

But nouveau is sufficient for the need we have. The only annoying thing for me was the configuration tasks the user had to do before launching a vm. This is fixed with horizon-mandatory-config file, it's enough for me at this time.

I took a look at installation of rpm nvidia driver file, but I found it was out of my abilities in thinstation, to install a rpm, first, and then debug nvidia driver... I chosed the lazy way.... waiting for Don to manage this ;-)

Thanks
E.T.

The lift on the Nvidia driver is quite a bit of work, as I mentioned earlier. I don't personally have any real use for this, so likely it would need to be a sponsored effort.
