xrandr stops working

I use xrandr because I access by VNC server from both home and work, and I have different size monitors.

I've noticed that often, after the span of a few days, xrandr resize no longer works.  That means, I give it the
command, and the server doesn't resize.  Mysteriously, it generates no error message, either.  When I try
to resize using the verbose command line option, there's no clue there as to why it fails, either. 
(Subsequent querying of xrandr shows that xrandr itself "believes" that the size didn't change, for what
that's worth.)

I can't find error messages in the VNC server log in ~/.vnc, nor anywhere else.

The VNC server lives on a RHEL 5.7 box.  The version of VNC is vnc-E-4.5.21561-1.

Best,

Need help

Hi
Is it possible to send only a specified window, via vnc.
I'm ready to do slight modifications if required but don't know from where
to start.

your support is highly appreciated.

Thank you in advance

No it is not possible to send a single window. A workaround can be to 
work full-screeen.

For unix/linux based vnc-servers: you can use a dedicated vnc-session 
for the purpose of the window.

For just a single window, why not use RDP or Xwindows?

					Thx, Phil

Changing VNC Viewer window to display host instead of desktop name

Hello.

Does anyone know if there is a way, with the free version of VNC Viewer, to have the window display the host it
is connected to instead of the desktop name?

Thanks.

High csrss.exe utilisation on XP with legacy software


I'm serving RealVNC Free Edition 4.1 from an XP32 SP3 box. When I run legacy Turbo Pascal programs from the
client the csrss.exe utilisation jumps up to 100% on every keystroke (or even if the application is put in
foreground) for several seconds and sometimes as long as a minute or 2. This stalls things and makes the
session unuseable. The Turbo Pascal programs don't generate much screen traffic as it is mostly file
shuffling so I don't understand why csrss is getting so much utilisation.
Anyone understand this and/or have a fix or workaround? It's a big job to redo the legacy stuff. (Clients are
XP or W7 machines and all demonstrate the problem).
Thanks.

Robert:

Most DOS programs consume 100% of CPU cycles in a Windows box.  I'm 
guessing this happens because DOS had no built-in 
process-scheduling or process priority, but I don't really know for 
sure.  U might want to look for old TSRs that could interrupt the 
CPU and execute a halt instruction.  I recall that there was one 
called "Rain," or something like that.  Again, this is only a guess.
