Description of problem:
Cursor changes sometimes totally black (like alpha channel mask).
Relogin fix this (but not jump to virtual console and back).
This seems totally randmom (but couple times after when using yum in

You mention that this isn't reproduceable. Without being
reproduceable, there isn't really anything to investigate.
Can you be more specific as to how to reproduce the problem?
Seems possible, that problem is caused by hard disk failure. (i lost
this disk suddenly, many bad blocks etc, and seems that first was
hitted /tmp partition)
At least, i can not reproduce this bug in similar (exact videocard
model but different motherboard) system.
Closing bug, I've never been able to reproduce this, and reporter no
longer sees the problem.
I see it after xscreensaver starts up... Once I get back to work, the
cursor is black.
Do you have the same hardware? Does it always happen with xscreensaver
or only sometimes? Is it dependent on the screensaver, e.g. is it
only for 3d screensavers?
Could you try with the 22.214.171.1243 snapshot in rawhide to see if it
happens with that version also?
>Cursor changes sometimes totally black
The mouse cursor?
Yes, the mouse (X) cursor
In my case, xscreensaver wasn't culprit (cursor turns black right
Same system with fresh FC2 install (and new disk :) ), no problems at
all, seems 100% HDD failure for me.
Ok, can you add 'Option "swcursor"' to the Device section of your
xorg.conf, and restart the server to see if that makes a difference?
If so, it may be a problem in the r128 driver's hardware cursor
If that doesn't help, can you try also adding 'Option "noaccel"' just
to see if it makes a difference or not, and then try both options at
once. That tests all 3 possibilities.

Also have this problem, using the r128 driver, only started after I
added KDE to clean "Gnome installation" (from the Fedora 2 CDs)
I have the same issue. I am using the r128 driver, and the mouse
cursor becomes a black outline after any invocation of xscreensaver.
I tried the tests suggested by Mike Harris, with the following results--
Option "SWCursor" solves the issue
Option "noaccel" does not solve the issue
Option "SWCursor" with Option "noaccel" solves the issue
I'm guessing that means noaccel has no bearing on the problem. But
then, I'm just an undergrad. :)
I hope this is useful.
Ok, from the information in comment #12, I think it is safe to
conclude that this is a driver bug in the hardware cursor init
code, which might be ordered incorrectly perhaps. Other drivers
have had similar problems in the past like this also.
Thanks for providing this information.
Same problem also in FC3 with more serious issue (see bug #138822).
My [relatively] new system has a Rage 128 AGP video card in it with this same
issue. I upgraded to Rawhide/Development and this issue continues to happen.
Just another data point..
I was able to restore it to the full-color cursor one time by switching to a
text-based virtual terminal and then switching back to X, but I could not
replicate that consistently. Sometimes, the cursor isn't completely black but is
rather a black-and-white version of the full-color cursor, including the
busy-cursor animation. At other times, it's completely black.
