We have just begun using some of the X11 features of our X11/NeWS
server (OPEN WINDOWS 1.0), and are having some birthing pains.
When we try to run xterm from a System V client, the server returns
the following error:
X Protocol error detected by server: integer parameter out of range
Failed request major op code 2 X_ChangeWindowAttributes
Failed request minor op code 0 (if applicable)
ResourceID 0x40001a in failed request (if applicable)
Serial number of failed request 72
Current serial number in output stream 77
Can anyone explain what is going on? What, if anything, can we
do to fix the problem?
Thanks for your help,

Versions of xterm dating from X11R3 and before have a bug where they set a window's do-not-propagate mask to an illegal value, ~0. (This mask is restricted to device events only, and ~0 contains mask bits for non-device events.) Older servers (X11R3 and before) didn't detect this error. Newer servers, such as X11/NeWS and X11R4, will generate the error you're seeing. The only real fix is to get a more recent version of xterm. I believe that xterm doesn't set the illegal value until it creates a scrollbar, so you might not get the error if you turn off xterm's scrollbar. s'marks Stuart W.

The problem is not in the server but in xterm: +The problem is that xterms in releases up to X11R4 had a +bug in them. The bug is that they call XGrabPointer with an +even mask that has values set that shouldn't be (xlock, FrameMaker, +and a few others do this as well). + +The Sony X11R3 server has a lot of X11R4 "fixes" in it, and this +includes the code that checks for these "out of range" values. + +The solution is to assume that the Sony server is as tight as the +R4 server is, and tell the server to be "backwards compatible". +To do this, create the file ~/.xserverrc, make it executable, and +put the lines + + #!/bin/sh + exec /usr/bin/X11/Xnews bc + +in it (note: no - before the bc). After you restart the server, +things will work fine. The solution on X11R4 is to run xset bc. I don't know what the solution is on X11/NeWS or on HP-UX 7.0. Anybody out there know what to do?
