I am already using XFree 4.3 (on most of the computers) and RDP 5. I might try compiling rdesktop from the CVS though.

Our main problem of the > moment is speed. This isn't a problem with PXES, but rather with the rdesktop implementation. Honestly, there isn't much anyone can really do to speed things up and here's why. Microsoft's RDP client does not grab the screen and draw it. Instead, it sends GDI calls to the client, which the client interprets and displays using its own local GDI. This makes for amazing speed, as rather than sending a bitmap of a box, or even instructions on how to draw the box, it simply sends something more like DrawBox(800x600) to the client. This makes communications blistering fast. The rdesktop client, on the other hand, has to take every single command, translate it into X calls, and execute them. There is a noticeable delay in doing this. I would suggest switching to XFree86 4.3 in PXES and using RDPv5 (if you aren't already) to gain some slight speed increases. I have also found that rdesktop compiled from CVS tends to run quite a bit faster than the 1.3.1 release. -- Chris Gianelloni Release Engineering - Operational/QA Manager Games - Developer Gentoo Linux ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
