Description Jack Neely 2011-10-05 21:21:10 UTC

Description of problem:

On my RHEL 6 dual monitor system, occasionaly the mouse cursor will vanish when moved to the right hand screen.  Mouse cursor is always normal on the left hand screen.  The windows get focus as normal (focus follows mouse) but on the right screen there is no image to visually tell where the mouse is.

This look very much like Bug #537065

It's difficult to say for certain, but I believe this bug should be fixed already and will be available in 6.2.

Comment 3 RHEL Program Management 2011-10-07 16:17:45 UTC

Since RHEL 6.2 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.

Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.

Several people at our company have seen this as well. VMware Player seems to trigger the problem quite often. The messages below resulted and the cursor would disappear when it was on one of the two monitors. After the problem showed up, logging out to try to recover resulted in just a black screen and I had to reboot.

Hopefully 6.2 resolves this.

Comment 5 David Thorarinsson 2011-11-08 15:53:41 UTC

I have this exact problem with a dual screen setup using Nvidia graphics adapter. 

From what I understand, this has already been fixed (https://bugs.freedesktop.org/show_bug.cgi?id=35360). My problem is that I cannot use my dual screen setup because of this bug. This has also been reported in Fedora as far back as May 2010 (Bug 593695).

If this won't really be fixed in the near future then my solution will be to go for the Nvidia binary drivers as the problem doesn't exist there. It isn't what I want to do but I am out of options it seems.

Funny that we are so intent on wanting open drivers so problems can be fixed quickly etc. This problem has been around for quite some time but it is still there. And the only real fix for me is to use binary drivers...

Comment 6 Ben Skeggs 2012-02-10 05:37:45 UTC

This should be fixed in RHEL 6.2, can you confirm?

Comment 7 Jack Neely 2012-02-10 15:17:56 UTC

I've not been hit by this bug recently and I'm running 2.6.32-131.17.1.el6.x86_64.

Any other data points?

Thanks for the updates, closing :)
