RE: [pxes-devel] PXES RDP Speed

[Diego T. M. <di...@in...>]

PXES is just the platform to run an RDP client, and rdesktop is just
only one of those clients.
You can try LINRDP (demo included in PXES 0.9 PREBUILT image).
Using a PREBUILT image (i.e: ISO) , select the LOCAL session (default),
click the configure icon in the PXES desktop, configure some LINRDP
parameters to suit your need (i.e: server IP), the click the RDP client
icon (top right).
