Xrdp: Can I play 3D game remotely using xrdp (RemoteFX)?

[fpemud]

I have a workstation machine, which has an integrated Intel GPU and a dedicated AMD graphics card.
I'd like to install xrdp and some 3D linux games (such as portal/portal2) on my workstation, play the games remotely using my notebook (I can install any linux/windows RDP client on it). The workstation and the notebook are both in my home LAN.
The games should be rendered using the dedicated GPU.
Can I do this using the current latest version of xrdp? If not, what needs to be done?

BTW, I'm curious why there isn't one sinlge game related issue here.

If you use glamor when building xorgxrdp (--enable-glamor) you should be hardware rendering. Then a remotefx session should work well. Glamor only works well with Intel and AMD GPUs, if you want to use NVidia there is another way.
One issue is many shooter games grab the mouse and work from relative mouse movement only. From what I've seen, RDP only has absolute mouse messages. So avoid games that grab the mouse or we have to look for a fix.

and whats the way for Nvidia ?

[lixaotec]

@jsorg71 what is the other way for NVidia?

[jsorg71]

@lixaotec The 'other way' for NVidia is the nvidia_hack branch discussed in #1422. We should create a new issue as it's not really related to GFX.

[jsorg71]

I created #1697 for this.

@jsorg71 Hi, does xorgxrdp support hardware rendering on arm platform with mali gpu?

nvidia_hack crashed in Linux 5.8.14-gentoo with nvidia-drivers 455.28, it works occasionally, succeed 3 times in
20+ attempts，but it's exciting thing. Looking forward to your great work!

I had make these stuff work once again, windows move more smoothly via xrdp using mstsc client to connect, but maybe loss some power
