[Dorset] XDMCP connection problem
Hi I connect to local machines (called fleet and golux) using XDMCP (using Xephyr on a laptop) but am just getting a black screen since upgrading my laptop to Debian Jessie. Xephyr -query fleet :1 Xephyr -query golux :1 give black screen. I can connect to the laptop XDMCP server fine: Xephyr -query localhost :1 and ssh -X fleet xeyes works fine. Using Xnest instead of Xephyr make no difference. This was working fine a few weeks back prior to the laptop upgrade. No iptables rules. Logging into fleet or golux from other machines also running Jessie is also fine so the XDMCP server on fleet/golux is OK. Does anyone have any advice on debugging this.

Thereafter disconnecting cable, ifdown eth0 and retrying XDMCP over wireless again also works. So some strange networking issue.

Re: [Dorset] Remote Desktop to a Raspberry Pi
Hi John On 20/04/15 13:14, John Carlyle-Clarke wrote: Using the RDP server on Linux doesn't really gain you much over VNC (other than making it easier for Windows clients to connect). The best thing about RDP on Windows is that it hooks the graphics layer to send drawing primitives and instructions instead of just updating rectangles of pixels, which is very efficient. It has several levels of protocol though, and the lowest is pretty much VNC (remote framebuffer). The smarter versions of the protocol have never been implemented on Linux and so the RDP server just wraps VNC and tells the client to fall back to the lowest protocol level. That's very interesting. I'd noted that xrdp relied on VNC for the backend and that had pushed it back to must try this one day status. The only test I'd run in the past was RDP client to Windows XP, and your description explains the impressive speed. I agree that remote X11 is very useful but I've always found that it works best for simple (dare I say old fashioned?) X11 apps like xterm and worst for graphically complex things like browsers. It's just about usable over a good WAN connection for simple jobs but seems to be very sensitive to latency, and the effect is multiplied for complex applications. One tool that I've found to work very well is x2go. I'm not sure if it's available for the Pi but I've used it quite a lot on desktop machines. There's a Windows client which works well too. http://wiki.x2go.org/doku.php It's not faultless. Not all features seem to work perfectly, but it's pretty good. I see that uses NX - will definitely be giving it a try. But it looks like nxagent needs a major rewrite to stay compatible with modern desktops.

A hair-tearing situation!!! Supply a hard drive FIRST and ask them to access the Lacie and copy the data across and until you have checked the results, DO NOT LET THEM FIX THE LACIE but send it to Lacie once you have your data. Unfortunately, it will be a rare IT guy who actually listens to and understands what you have actually asked for! Lacie do not offer a fault-recovery processing facility.
