RE: Strange Question: Xfree86 on Terminal Services(RDP)


To add to what I said the 16bit and 8bit color is the color depth for the
Terminal Server Session.  Does anyone know why running at 8bit color would
crash X?

Thanks

There is only one cygwin1.dll on the system, however after more testing I
found that X-server at 16bit color is stable and works, but at 8bit color it
still crashes.

Also I have tired engine 1-4 and I get the same results.

Thanks

Noah,

Your problem is likely unrelated to RDP.

To test this hypothesis, login to the console of the Terminal Server and 
run Cygwin/XFree86.  See if you can make it crash.  I suspect that it 
will crash just as easily on console as it will through RDP.

Now, what I suspect is that you have multiple versions and copies of 
cygwin1.dll on your Terminal Server.  Lots of projects come with a copy 
of cygwin1.dll and it doesn't matter that many of them may not appear to 
be in your path.  You need to make sure that there is one copy of 
cygwin1.dll on your machine, and one copy alone.  There is more 
information about this topic here:

lation


At the risk of being crude, I have told many people this before and it 
often results in some sort of response claiming that having multiple 
copies of cygwin1.dll on their machine shouldn't be causing problems for 
them.  I then restate what I said, they delete the extra copies, and 
everything works.  Please, if you have multiple copies of cygwin1.dll, 
take my word for it that they are the culprit.  If not, we will need 
some more information to figure out what is causing your problem.
