I have recently upgraded my laptop to run Windows 7 64 bit Edition. I have been really impressed with this installation and the upgrade in software. What I have had some difficulty with is getting CYGWIN installed on my machine.

The issue I have been having is that every time I would try load up a configured fvwm2 XSession I would get a fault in the code. I did a lot of searching on the internet and what seems to help fix most issues with this is running the rebaseall command.

Documentation for this can be hard to find on the internet. There is currently no man page for this command. To find more information about it go to /usr/share/doc/Cygwin and read the rebase-3.0.1.README file.

According to the documentation

" The rebaseall utility is a convenient way for users that suffer from the
Cygwin rebase problem to rebase their entire system (i.e., all of their
DLLs) ..."

To run the rebaseall command you need to be in a ash shell. To get there do the following from a Windows Command Prompt (cmd).

c:> cd c:\cygwin\bin
c:\cygwin\bin> ash.exe
$ ./rebaseall -v

After I did this, I was able to run startx and everything worked great. What I did find interesting is that the installation seemed to run very slow after I did this. After installing and reinstalling over and over again I said to hell with it and left things alone. What I found that after leaving my computer running and working in cygwin fora little while, things seemed to get faster.

I hope that this helps out. I have read online where people do a rebase after every cygwin installation.
