Glamor and GPU

[EvilDevRu]

Hi. I tested glxgears by 3 videocard:

1. 9600k, Intel UHD630 - 3000 frames
2. Ryzen 2600, AMD r9 270 - 1500 frames
3. Ryzen 2600, Nvidia 660 - 1500 frames
   I compiled xrdp with glamor option but dont see effect. What am I doing wrong or where can I find information about this?
   Google ask me that xrdp work with amd and intel gpu but I dont see performance.

Hi @EvilDevRu

There is no glamor option for xrdp.

Did you mean to raise this against xorgxrdp ?

[EvilDevRu]

I compiled by this https://gist.github.com/rkkoszewski/aa531cee7126edf329b76bdd0546f502
Mint 20, Cinnamon

If you run ./configure --help when you build xrdp itself, you'll see there's no --enable-glamor option. This only applies to xorgxrdp.

You need to build xorgxrdp with --enable-glamor, and then run xrdp with the Xorg backend so that you pick it up. If you use the Xvnc backend it won't have any effect.

Does that make sense?

[EvilDevRu]

Yes, I compiled xorgrdp with glamor, sorry my english. But this no effect.

Hi. I have similar problems. I'm running Ubuntu 20.4 on Proxmox. I have configured PCI passthrough for an Nvidia GTX 1080Ti. Nvidia-smi can see the card, CUDA works as it should, but I'm unable to get GL support for xrdp. I have compiled xrdp and xorgxrdp with glmaor. In my log I see:
.....

I have read and tried everything I can find google.
Any help to solve this issue would be greatly appreciated

glamor needs to have access to /dev/dri/renderD128 so make sure your user can open it. You might have to add your user to 'video' group or 'render' group. xorgxrdp glamor does not need access to /dev/dri/card0.
Glamor only works with amd, intel and nouveau kernel mode drivers. If you want to use nvidia drivers, there is the nvidia_hack branch.

My user is a member of both video and render group.
I cant see the nvidia_hack branch. Could you paste a link in here?

[jsorg71]

Using NVidia is a work in progress so you will need patience.
