[FreeNX-kNX] blank screen issue

[Aidan Marks]

Hi

gentoo hardened server with nx-3.2.0-r3, nxserver-freenx-0.7.2-r2, 
xorg-server-1.4.2, kde 4.0.5

gentoo laptop client, nxclient-3.2.0.13

client sees a blank screen after the !m. this used to work fine, can't 
pinpoint the regression.

startx on the server locally starts kde fine.

session log:
