[coLinux-devel] "Heavy" apps always crash X/VNC

[Jason A. P. <pat...@pc...>]

It seems that no matter what I do, I can't get "heavy" apps to work 
properly.  I've tried under both Cygwin's X server running in 
-multiwindow and not, along with vncserver with the TightVNC viewer on 
Win2K to view the desktop.  Examples of "heavy" apps are kmail (running 
the Kroupware extensions) and xchat.  These are the only two I've tested 
so far that I really need working.  When connecting to cygwin X, the 
apps end up just crashing the X server and XWin.exe dumps core and 
reports an

Exception: STATUS_ACCESS_VIOLATION

error message. I did some Google'ing but didn't find a solution. I was 
pointed to running the startxwin.bat script instead of just launching 
XWin.exe, but that didn't work either.

When using the VNC server/client to access the apps, I couldn't get a 
full instance of KDE desktop up and running in order to launch kmail.  
It would stop at different times, but usually leaving the splash screen 
up and not getting to the full desktop (although it made it there once, 
but then kandalf's tips were hung on the screen and I couldn't close the 
app).  I switched to using icewm, and that came up completely and was 
going to let me launch apps.  So, I attempted to start konsole, which 
got all the way to bringing up the window and the menus but not a 
prompt.  The block cursor just stayed in the top left of the window, but 
no prompt showed up.  I couldn't even close the window or interact with 
it after that.  Even killing it from the console didn't remove it from 
the screen.  The disconcerting thing, though, is that the VNC viewer 
will just lock up and stop responding.  I click the 'X' to close it and 
a dialog pops up from Windows telling me that this program is not 
responding, do you want to end it now.

I've noticed some of these kinds of issues before with exporting X apps 
from other Linux servers on the network to cygwin's X server under 
Windows.  However, the cygwin compiled versions of KDE apps/desktop seem 
to work fine (albeit, very slowly).

Don't know where to go from here.  My goal was to get the Kolab 
groupware server installed and running (which I was successful at doing 
and that seems to be working) and also the KDE PIM apps that have the 
modifications to work with the Kolab server.  It seems the KDE PIM apps 
may have problems interfacing with X/VNC or something.  But then, why 
would xchat crash cygwin X, too?

Thanks for any help (and for the previous help; I was able to get back 
into the filesystem after the updates that fixed the bootparams bug).
