RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description David Jaša 2012-06-11 11:14:30 UTC 
Description of problem:
Don't grab mouse cursor on client --> server mouse mode switch. This is a minor annoyance but spice-client doesn't suffer with it.

Version-Release number of selected component (if applicable):
virt-viewer-0.5.2-9.el6.x86_64
spice-gtk-0.11-11.el6.x86_64

How reproducible:
always

Steps to Reproduce:
1. connect to linux guest
2. have the keyboard focus in the client
3. switch to the console (using ctrl-alt-Fx from Send Key menu)
  
Actual results:
mouse pointer gets grabbed

Expected results:
mouse pointer remains intact

Additional info:
this could go to ZStream (proposed) to avoid unnecessary "feel" changes in spicec -> remote-viewer transition.
Comment 1 RHEL Program Management 2012-07-10 08:49:40 UTC 
This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.
Comment 2 RHEL Program Management 2012-07-11 02:01:58 UTC 
This request was erroneously removed from consideration in Red Hat Enterprise Linux 6.4, which is currently under development.  This request will be evaluated for inclusion in Red Hat Enterprise Linux 6.4.
Comment 3 Marc-Andre Lureau 2013-03-20 20:37:42 UTC 
That will have the side effect that any crash/stop of the vdagent will result in mouse being "released", even if the user is doing mouse grabbing. Not only grabbing, but mouse move as well.

I believe it's more important to keep the mouse continuously working even if vdagent is stopped or crash.

If the mouse is already in the context of the client, why shouldn't it be till there, even if switching to console? However, if the mouse is not over the display, I think it would make sense to not take the grab.

Agree with the above?
Comment 4 Marc-Andre Lureau 2013-03-20 20:52:30 UTC 
(this "minor annoyance" should not occur if the guest is configured with usb tablet)

I think that the line should be drawn a bit further: the cursor should be kept inside only if some button is pressed, iow if user is performing drag'n'drop - but if that would be hard, then I'm in favor of releasing the mouse always.

The reasoning is:
1) the odds of agent crashing while user performs dnd - the only possibly destructive scenario - is quite low
2) when agent crashes while user works with mouse and the mouse is released, it's matter of one click on button that user already holds == almost non-event
3) the odds of user having mouse pointer on top of client while something ordinary happens that would grab the cursor are pretty high compared to 1) - just logout can o it (on linux and iirc on XP VMs)
4) the action to release the cursor suddently is quite annoying - having to interrupt what you are currently doing, take you hand off the mouse, press the key combo (RHEV's shift-f12 isn't exactly left-hand-friendly key combo), return the hand back to mouse, resume the action you did want to actually do
