麗 -Ulalaca-

xrdp-powered remote session broker / projector for macOS

NOTE

• STILL IN HEAVY DEVELOPMENT, NOT SUITABLE FOR PRODUCTION USE YET

• This software requires xrdp and XrdpUlalaca to be installed for work.

• This software uses ScreenCaptureKit which introduced with macOS 12.3, so macOS 12.3 or higher version is required.

• The name of this project, '麗 -Ulalaca-' is derived from the song "Urara" from the music simulation game beatmania IIDX.

ulalaca's Issues

audio redirection support

SUMMARY

audio capture has been added since macOS 13.0

LINKS

https://developer.apple.com/documentation/screencapturekit/scstreamconfiguration

outgoing data from IPCServerConnection.write() corrupts when optimization option turned on

H....EL..P.....

sessionbroker doesn't seem to work when launched as LaunchDaemons

concurrent sessions not responding until connect same host using chrome remote desktop

maybe this is related with #2

Connect to RDP session causes crash on hackintosh with RX580

I am testing on a hackintosh with i7-12700F, RX580, running Ventura. xrdp immediately crash after logging in the session. The session screen remains blue. On rare occasion I can move the mouse cursor for a bit before the crash.

I installed following this guide: https://teamunstablers.notion.site/xrdp-Ulalaca-Getting-started-f82b0c55f0b540a6ac277cc5902361b1

The specs and the EFI is given here: https://github.com/laggykiller/Hackintosh_MSI_B660M-A_WIFI_DDR4

Note that I also have a RTX2070 inserted into motherboard, but disabled by EFI. Not sure if this is the culprit?

Here is the crash report:

Btw I also tested with Sonoma. After logging in, xrdp does not crash, but the rdp screen stays at blue screen. The mouse cursor is teleported to left upper corner, and I cannot move it in the RDP session. However if I left click in RDP session, I can see that it went through and responded to my left click.

The package requires a newer system version

Hello! I'm installing release of ulalaca session broker (0.2.2 and 0.2.3-pre1) on Monterey ( fresh install, on Proxmox) and got this error

How to solwe it ? xrdp-tumod installed

Random disconnects from RDP session on M1 macmini

RDP session disconnects randomly. I cannot find specific actions that can trigger the disconnect, but seems like:

• It usually occur when I open Brave Browser, interact with websites and closing the browser
• No (or much less) crash if I am using Google Chrome
• Sometimes when I am not using Brave Browser it still crashes
• One way to trigger is to open youtube and scroll up and down
• More disconnects if I am using Guacamole compared with Windows Remote Desktop

I installed following this guide: https://teamunstablers.notion.site/xrdp-Ulalaca-Getting-started-f82b0c55f0b540a6ac277cc5902361b1

Here is the settings for guacamole:

Settings for Guacamole

Note that I am using arm64 Ventura, not sure if this is related.

Here is xrdp log from one of the crashes, copied from console:

• ScreenCaptureKit calls SCStreamDelegate::stream: (SCStream!) stream didStopWithError: (Error!) error when something is going wrong
  • error parameter is marked as nonnull, but ScreenCaptureKit(or ReplayKit) actually passes nil

어떻게 해야 하지

• Apple에 버그 리포트?

• guard let error = (error as? Any) as? Error 같은 임시 조치를 해야 하는데, 이게 먹을까?

• nonnull이라면서 왜 null인데.. 얼탱이 X

Crash after logging in via xrdp

Hello, I have followed the guide here
ulalaca-xrdp
and installed the Session Projector app, but uppon connection with the RDP client mstsc.exe from another computer, I get the "Your Remote Desktop Services session has ended." message immediately after signing in via the xrdp gui. I am using MacOS Ventura Hackintosh with an RX 580 and attached is my /etc/xrdp/xrdp.ini which has been edited per the guide.
Any help would be much appreciated, thanks
