<freenx-knx@kde.org><br /> Emne: [FreeNX-kNX] Screen Re-Draw
Problem<br /> Til: User Support for FreeNX Server and kNX Client
<freenx-knx@kde.org><br /><br /><br />> Hi list<br />><br />> I
have a specific question about how screen redrawing is handled by NX<br />>
(or Xserver in general).<br />><br />> The actual problem that we have is
that the screen is not properly<br />> re-freshed on the client after
switching to a text console and back. The<br />> user has to actually move
the mouse around to make the screen refresh<br />> itself ...<br
/>></p><p>Well, a workaround for this problem (if you use KDE) could be to
use 'khotkeys' and add a key-combination to execute this command: 'dcop kwin
KWinInterface reconfigure'.<br />I use this with CTRL+ALT+L to get the palette
fixed when resuming a KDE session with nx.</p><p><br />> we use the !M
nxclient 2.1 and nxserver 2.1. The nxclient and it's<br />> associated
Xserver is running in a special jail. the Xserver is patched<br />> and
runs as non-root. the nxserver is normally installed on a debian<br />>
testing machine.</p><p>Maybe you should ask NoMachine support this question,
since this list is about FreeNX and most people here answers questions about
FreeNX...</p><p><br />> The same combination works great when the client is
started "normally",<br />> let's say from an ubuntu workstation.
So the problem must be the<br />> hardened jail...<br />><br />> Could
someone explain how screen refreshing works? I need to understand<br />> the
theory behind it so that I can solve our problem. Or does someone<br />>
have an idea what could be the cause of this behavior? How or when is<br />>
the screen re-drawing triggered?</p><p>My understanding is that this works like
normal X11, so maybe you should ask the X.org people this - they may be able to
answer you with the inner workings of X.</p><p><br />/Terje</p>
