Setup: Decstation 5000/200, Ultrix 4.1, mwm, Xtm2d.
When I start up the X server, it has a process size of approx 2.5
megs. After I start and stop a few windowed applications, the process
size has grown to 12 Megs. When it gets to about this size, it
thrashes each time i move a window, as I don't have hundreds of megs
of real RAM. Something is seriously wrong in my setup I fear. Does
anyone have any clues?
Probably unrelated, but when I start a dxterm, I get the "mwm: Invalid
icon bitmap, not depth 1" error message on my console.
Any and all help appreciated.

Does |> anyone have any clues? Sounds very familiar to me :-) If you disable save-unders, which are turned on by default in Ultrix 4.1, you will see much better performance when using mwm. Here is related information on how to do this: Well, on my DS3100, ULTRIX 4.1 and mwm 1.1, mwm _was_ a hog until I figured out what was going on. There's a bug in mwm -- it uses save-unders BY DEFAULT (it isn't supposed to unless you ask it to). The 4.1 X servers implement save unders, but (alas) not very effeciently (plus they aggravate a memory leak). So, what you should do is tell the X server not to use save unders. This is true for ALL the 4.1 X servers (Xcfb, Xtm and whatever the server for the PX board is). In your /etc/ttys file, add the -su option to the line that starts the X server. Mine looks like this: :0 "/usr/bin/login -P /usr/bin/Xprompter -C /usr/bin/dxsession -e" none on secure window="/usr/bin/Xcfb -bs -su" |> |> Probably unrelated, but when I start a dxterm, I get the "mwm: Invalid |> icon bitmap, not depth 1" error message on my console. Unrelated. I'll let someone else explain this to you - I'm wiped out. Nat

Since I'm not running mwm, I'm not sure this is a mwm bug.

The problem arose the first time I popped up some menu. With tvtwm the problem was even worse. It's a problem with save-unders, it can be worked around by starting the X server with the -su (no save-unders) flag. This is either in the xdm server configuration files or (if you're using xdm) or in /etc/ttys. After that, the X server's growth is not significant (ie. doesn't grow to 20M as soon as I do anything). /.salvador spa@fct.unl.pt (posting from inesc.pt)

This problem is documented for ULTRIX 4.0, the solution stated in the release notes is to add the "-su" option to Xcfb or Xtm2d to turn off the SaveUnder feature. Try it and see if it helps. -- Dan O'Neill Cadence Design Systems, San Diego, CA UUCP: {uunet|ncr-sd}!asihub!dano ...cadence!dano Domain: dano@autosys.com dano@cadence.com
