Ok the method we thought would work didn't and would like to try the xorg.conf 'software cursor' possibility.  How exactly do we do that? We boot from CD with settings on floppy in our environments.  Would we put the xorg.conf on the floppy?  Step-by-step instructions would help.

Sorry. I thought when we chose related question it would be connected to the original question

Does the cursor appear like black square or so or terminal server client simply ignores cursor themes and you have to live with basic X11 arrow ?

Black cursor.  I'm not sure what the rest of your sentence means - 'ignores cursor themes' and 'basic X11 arrow'?  


What exactly does the setting you suggested to? And where is it? The only thing I can connect to it is a line in the X Server section "X Server section:
X_DRIVER_OPTION1="swcursor On"

Is this what you are referring to? What is this supposed to do?

The symptoms are per the user:

The cursor will change from a solid black bar to a broken bar resembling
the letter  T. When this happens, the cursor does not always hit the mark we
are  aiming for. For example: in this paragraph, if I wanted to
change the word "resembling" because of a spelling error, I would click on
the spot     where the change needed to occur but the cursor would go to the
word     "the" in the line below instead. Or if there was a sentence
above the    desired word, the cursor may go to one of those words instead.

Do you know of any alternative to Thinstation? Apparently as well the latest Rdesktop resolves the problem. Is there a way I can inject that into Thinstation? Or some other similar product?

(from "man radeon")

       Option "SWcursor" "boolean"
              Selects software cursor.  The default is off.

       Option "NoAccel" "boolean"
              Enables or disables all hardware acceleration.
              The default is to enable hardware acceleration.

i'd guess:
X_DRIVER_OPTION1="SWcursor" "On"
or even (works on normal Xorg:
X_DRIVER_OPTION1="SWcursor"

for more options i would need /var/log/Xorg.0.log to understand what graphics card is in thinstation.

Sorry I'm still not understanding.

What is Xorg?
What is software cursor? (Which begs the question what 'hardware' cursor would be.)

I guess the original question was the black mouse cursor. Have you had that problem? Have you used this fix to resolve it?

These are basic white box workstations with a variety of video cards. Those of them that have hard drives with Windows installed on them do not have this problem using the Windows RDP client regardless of which video card they have. It's the ones using Thinstation that don't seem to work. For example if I were to stick our bootable Thinstation CD in a computer that had a hard drive with Windows installed on it that had no black cursor problems using MS RDP, the same computer would have a problem with the Thinstation RDP client.

Hardware cursor is a sprite that X11 server drags around the screen. Should graphics hardware choke for some reason it gets badly distorted.
Software cursor is drawing it on a picture by pixels (ok BLT-s).

I had black/inverted/broke hardware cursor problem tens of times in last 15 years of me with X11.
Turning to software cursor or disabling acceleration altogether resolves the issue.
Knowing video card in thinstation would help to find other options to resolve the issue at less performance penalty.

Thanks. Sorry but I think I might have missed the point of the  X11 reference originally - what is X11? We are RDP'ng into a 2008 TS with the latest Thinstation CD. Is X11 some kind of Xserver?

X11 is the UNIX/Linux graphics framework which includes X11 server you call Xserver
I am only surprised about the way *Linux* running on thinstation accepts X server parameters.
Can you check some other Linux LiveCD (knoppix, opensuse,ubuntu) to see if the problem persist with more recent video drivers.

Sorry for turning you into a Linux tutor here but  modifying the Thinstation floppy .conf text file is about the limit of my Linux knowledge so a lot of the terms you are using don't resonate with me. We have resolved the problem however by finding the Danish 'build-your-own Thinstation ISO' site as that version of Thinstation had Rdesktop 1.7 which did the trick.

One more Linux question however.  Would the XorgX11 section be at all relevant for connecting to a Windows 2008 TS Server? Does Windows 2008 look like an X11/Xserver to Thinstation/Rdesktop?

Yes, X11 server is another name for display driver.
X11 client is application displaying something like rdesktop which in turn connect other end to windows terminal service.
Probably aftermarket firmware (a normal term for "build your Danish ISO") is a way to go.

It has a proper (more recent) graphics driver in place and a better rdesktop (i thought thinstation has something with microsoft in it, turns up no)

I am completely fine if you accept your last answer giving the link to source.
It would take another week for me to get through some Linux LiveCD (i´d start with OpenSUSE or Ubuntu), confirm their video drivers + rdesktop work fine and instruct you how to build minimal ISO that does what you wany.

Thanks for the tutoring. It may not have answered my question here but it will be of use to me later I'm sure.
