Why become an xrdp developer?
●
I am a user of both FreeBSD and xrdp
●
xrdp couldn't be compiled on FreeBSD before
●
No more FreeBSD local patches to unbreak builds
●
“Upstream First” policy
– submit lots of PRs, bugfixes
●
Motivation of making xrdp FreeBSD compatible,
because I'm a xrdp user on FreeBSD!

Linux Desktop on Laptop is a struggle
●
I don't want to manage:
– Wi-Fi chip is Broadcom BCM****, the driver is found at…
– compatibility with new hardware
– everytime when I renew my laptop!
●
Linux Laptop is a struggle, BSD is a bigger struggle!
●
Relieve from such struggles!
I know it almost works fine, though...

Audio redirection
●
Supported, but needs additional pulseaudio modules
– built in SUSE? if not, let's add it
●
xrdp v0.9.4 supports following codecs
– LPCM, Opus, MP3, AAC (still experimental)
●
Requires client support
– Windows client supports MP3 and AAC
– FreeRDP supports LPCM only so far
Slide 25

Graphics remoting

– RemoteFX
– Adaptive RemoteFX is not supported yet
●
RemoteFX is the best in most usecases
– smooth scrolling, smooth video playback
