X Server Cursor Option

[Simon Farnsworth]

I've asked you to ensure that you keep a relevant mailing list in the loop. 
Please respect my request - I made it for good reasons.

I honestly can't answer your questions - I never need the X cursor, so it 
suits me to have it completely disabled and impossible to re-enable. I pointed 
you at XFixes, because I believe that the code used by the HideCursor request 
is closely related to the code that the -nocursor option amends.

If you keep this on the xorg mailing list, rather than insisting on mailing me 
privately, you may get helpful answers from other people.
