Greetings FreeBSD
When running XFCE4 I will lose the mouse pointer at times. This will
only happen when I have the driver set to "nv" in xorg.conf. The mouse
will still work as I can see where it is when I pass over icons and
watch them highlight. If I can stop on an icon, I can click and it
works.
If I drop out of the XFCE4 using ctl-alt-backspace, the mouse pointer
appears and all is well. If I restart the XFCE4, there is no pointer.
If I change the driver to "vesa" and restart then I have a pointer
again. The only way I have found to regain the pointer using "nv" is
to reboot.
All ports are up to date and I am running amd64 RELENG_7 as of last
Saturday.

If I should have posted to a different list please let me know. I have
also attached my xorg.conf.
TIA

This seems like a very strange problem. Let's try focusing on XFCE first.
Are any processes conflicting with drawing something on the screen, from your
description it seems like XFCE is a problem, but do other window managers do the
same thing ?
If it's not wm specific then I'd try chasing down the developers of
xf86-video-nv . Here is a starting point :
http://www.t2-project.org/packages/xf86-video-nv.html
Does the driver support any sort of 'debug' mode that you could log to file ?
....
Taking a walk through xf86-video-nv, it looks like there are a few bitshift and
& operators that use pointer and move things to and fro. ( in 64-bit land that
maybe these moves should be handled differently ? Or are these magic numbers? )
Take a look into the source, nv_cursor.c
Examining these lines :
#if X_BYTE_ORDER == X_BIG_ENDIAN
if ( m & 0x80000000)
*dst = ( b & 0x80000000) ? pNv->curFg : pNv->curBg;
else
*dst = TRANSPARENT_PIXEL;
This case draws the pixel transparently if it fails the test -- which seems to
coincide with what you're seeing. This is just a wild guess, it could be used
elsewhere though with the same affect.
But then again, since this is working at all, then it may point to
1. the wm
2. Xorg may have a problem reporting it to the wm
Hope it helps. Report back if you have any progress.
Later,
Bryant
