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...

xrdp-sesman ● a session manager ● authenticates user ● executes user session ● executes window manager

Slide 21

Slide 21 text

Wayland? ● Nothing's being done so far ● Maybe some xorgxrdp parts are reusable ● Someday in the future

Slide 24

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

Slide 25 text

Graphics remoting ● xrdp supports several graphics codecs – classic – NSCodec – RemoteFX – Adaptive RemoteFX is not supported yet ● RemoteFX is the best in most usecases – smooth scrolling, smooth video playback
