I found an interesting behavior of the rdesktop when
started (and compiled) under RH 7.2.
When I connect to a W2K box the display is corrupted
wich means that some characters are replaced with
colored boxes. When I start kcontrol and leave it
running in the background everything is fine. As soon
as kcontorl is stopped the next rdesktop has this odd
behavior again while the others wich where opened
while kcontrol was running are still fine.
When I start rdesktop with the resolution wich is
configured on X11 everything is fine nomather kcontrol
is running or not.

    Interesting. What exactle does kcontrol?

    I'm not running KDE, but when I'm using a geometry like
    1013x698, I get display corruption. Also reported by Joseph
    DiPaolo.

    I compiled rdesktop under RH7.3 and I have some strange
    behaviour, too.
    While I am developing under Visual Basic and I indent the
    code with tabs, somewhen the text disappears or shows some
    other code lines or strange bitmaps.
    I use a simple (second) X11 desktop (no special Windows
    Manager like GNOME or KDE) with only rdesktop running in
    fullscreen mode.

    I sort of have the same problem with RH 8, although my
    system is special in that I have 2 video cards and 2
    monitors. I don't know if it's related to my problem,
    however. I haven't noticed corruption over VNC, for
    instance, so I doubt very much it has anything to do with my
    XFree86 configuration.

    kcontrol = KDE Control Center. Ah. Well, I don't have the
    problem when I sumultaneously run this or any other app on
    Linux.

    I found that the crazy control characters change if you do a
    selection over the characters, or click on the line where
    the characters are, or resize the window, or change the
    font. Often times when I change the font, I can make the
    error go away temporarily, but not always, and this problem
    comes back eventually in a given session.

    I'm using 1.1.0 which comes with RH8.

    I'm using a revised rdesktop command line:

    # rdesktop -u myusername -d mydomain -l -b -g 1152x864
    myipaddress

    I guess the next step for me is to see if I don't get the
    problem at lower resolutions, or if an upgrade of rdesktop
    fixes me.

    The screen corruption was occurring for me on version 1.1.0.
    The problem went away for me by upgrading to 1.2.0.

    I have a 2 monitor system with 2 video cards, running RH8. I
    also always connect my rdesktop on a revised geometry with
    the -g option, to 1152x864.

    I found this occurs on only one system on my network, but
    I'm trying for the first time to connect 1.2.0 rdesktop
    (from RH9 Linux) to Windows XP on a brand new IBM
    workstation (the host running Windows XP Remote Connection).
    Then, when I login locally at the workstation itself by
    walking to it, the screen suddenly loses its hertz setting
    -- that's the best way I can describe it. I get something
    that looks like horizontal hold has been messed up. The only
    recourse I have is to reboot that system at that point. I
    cannot say this is the same problem you all are having -- it
    may be completely unrelated. I have not done enough testing
    to rule other factors out.

    Now, I never have this problem on any Windows 2000 Server
    hosting TS -- just this new XP workstation I'm testing against.

    I have the same problem. My system is running Mandrake 10.1
    community and is using the 1.3.1 version of rdesktop
    according to
    http://www.mandrakesoft.com/products/101/community/packages/DOWNLOAD.

    I have an older Radeon video card (dual head, but x only set
    up to use one).
