1. FRQ and mail archive shows may iinstances of "Can't open display "
on Win95 machines particularly laptops with no network connection.
Apart from firewall problems suggested by FRQ another explanation is
that the manufacturer (e.g. Dell) has installed a minimum Win95 set up.
To cure the problem run Microsoft Communication Wizard to install
required network software either from CD-ROM or CD image. If no live
network link is available you may need to ctrl-alt-delete to get out of
MCW once it tries to test the (e.g. non-existing modem on IR ) link.
Reboot and XWin, xterm etc may now run.
Very interesting. I had not yet heard of this.
2. Cygwin shows great increase in speed if antivirus software (e.g.
Network Associates V Shield) is temporarily switched off.
Yes, this is known. The least performance-inhibiting software that I
have found so far is Norton Antivirus... it doesn't slow down
Cygwin/XFree86, and it only has a minor affect (5% slowdown) on
compiling Cygwin/XFree86 (which opens and closes thousands of files).
On the other hand, Network Associates V Shield slows compiling down
about 150% and generally makes the computer unusable. Of course, I
don't run antivirus software when not forced to, cause I don't do stupid
things :)
