However if the application specifies it's own cursor you're lost. Egbert. ___ Devel mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/devel

Any idea? Thank you. Roy This has been discussed and answered many times. The answer is no. 1) X always must always have a cursor. 2) The cursor's appearence depends on the window it is over. You can change the root window cursor with xsetroot, and if another window doesn't specify a cursor, it inherits the cursor from it's parent. If no parent all the way down to the root window has specified a cursor then that window gets the root window cursor. But if windows have specified cursors explicitly, there's nothing you can do about that. Mark. ___ Devel mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/devel

Since this problem comes up quite frequently I have made an article at: http://xfree86.linuxwiki.org/AdvancedTopicsFAQ about how to do this. Egbert.

Re: Can I hide the cursor?
If you use XFree 4.3 with libxcursor, you can create a completely transparent cursor theme. -- Matthew on Wed, Aug 06, 2003 at 02:21:35PM +0800, tom wrote: I want to hide the cursor when I using touchscreen in XFree86 4.20,I found that this quesstion have been discussed three times,but no answer.Then,does this means I can't hide the cursor at all?Can xsetroot resolve this problem?I tried but faild.I just can't change the cursor with it.

Might help, but applications can change themes as well as cursors.

or use an empty pixmap for the old sytle cursors.
