Re: [Lesstif] "mwm" on Cygwin : heavy load

[Harold L Hunt II <huntharo at msu dot edu>]

Christian,

See, the problem here is that you are not reading what I am telling you 
about the -emulatepseudo parameter.

Let me explain.  Imagine that you would really like to have 
Cygwin/XFree86 running in 16 bit color, but that you would like to still 
be able to run applications that require a PseudoColor visual.  Well, 
the -emulatepseudo option creates a fake PseudoColor visual in addition 
to the standard TrueColor visual when running in TrueColor modes. 
Therefore, -emulatepseudo does nothing beneficial when you are already 
running in 8 bit color mode, as there is already a PseudoColor visual 
when you run in 8 bit color mode (both in windowed and in fullscreen 
modes).  Thus, LEAVE OFF THE FREAKING -emulatepseudo PARAMETER!!! 
There, thanks for reading it this time.

Now, as to the additional information you supplied, you did not specify 
if you left off the -emulatepseudo parameter when you ran with -depth 16 
and -fullscreen.  If you did not leave off the -emulatepseudo parameter, 
then I am not surprised that your problem did not go away, as 
PseudoColor emulation in TrueColor modes is a hack that is nowhere near 
completion, so it could very well be causing your problems.

On the other hand, Cygwin has gone through many revisions in the past 
few days (including new versions of the Cygwin DLL) and some of these 
revisions have been causing great problems for many users.   I suggest 
that you run Cygwin's setup.exe again and let it download and install 
any updated packages.

Could someone from Lesstif give him some notes on possibly renaming any 
configuration files for Lesstif so that we can rule out any custom 
configuration as the cause of this problem?

Thanks,

Harold
