I am compiling from source on NixOS. It has all the libraries it needs. I have enabled glamor and simd, but it did not work without them.

You need to pick a version of xorgxrdp which is compatible with your installed version of xrdp.

It looks like you're trying to compile a recent version of xorgxrdp against an older version of xrdp.

I am building xorgxrdp at v0.9.20, and xrdp at v0.9.25.1, is there anything wrong with this? I tried compiling the latest version, but it did not work. Thanks for your help. @matt335672

I finally got it to build (I don't know how, I didn't change anything) but glamor doesn't work. The screen is just blank. It worked just fine without it. The cursor on the screen is the correct remote cursor.

I can think of two possibilities here:-

1. Based on your description, make sure you haven't got a version of xrdp installed from a package, and a version you've built. If you do this, the shared libraries from one version get loaded by the other and bad things happen.
2. Glamor doesn't work on all platforms, which is why we implemented glamor, check list of support devices #322.

I am only using the new xrdp as a build input, not the already installed one. NixOS can do that very easily. As for the platform I am using, I am using i915-sriov as a guest vm. I assumed that was supported. Maybe it isn't thanks for the help.

Try disabling glamor at runtime by setting the DRMDevice to "" in /etc/X11/xrdp/xorg.conf`. That will tell you if it's glamor or not.

Where will it tell me that?

[matt335672]

Sorry - not being clear. Setting the DRMDevice will tell you whether the the blank screen is a glamor problem, or whether something else is going on.

It is still blank after setting DRMDevice.

The most likely thing is a build/runtime issue then.

I'm a bit concerned by this:-

I'm not familiar with NixOS, so I can't comment on your assertion. However, because xrdp uses dynamic libraries built as part of the project, it's very easy to get in a mix over this.

I'd recommend starting with a system with no version of xrdp installed at all, and building both from scratch. We can sort out compilation issues as we go along.
