Description bugz 2012-07-30 19:26:32 EDT
Description of problem:
My system has two 24"HP screens, one in the traditional landscope orientation
and the other in portait.

I wish to use them as two more-or-less independent displays, I don't want to
drag windows from one to the other, and I don't want to view my display
spread across them both.

I have DISPLAY=:0.0 and DISPLAY=:0.1

The graphics card is:
0f:00.0 VGA compatible controller: NVIDIA Corporation GF108 [Quadro 600] (rev a1)
0f:00.1 Audio device: NVIDIA Corporation GF108 High Definition Audio Controller (rev a1)

ItΕ› not well-supported by the nouveau drivers in either Debian Stable
or RHEL 6.3, so I'm using the nvida proprietary driver.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Install RHEL+KDE on a dual-monitor workstation
2. Configure displays 0.0 and 0.1
Actual results:
One screen lackes essential facilitis

Expected results:

Both screens to work independently

Additional info:

For this to work properly, each screen needs its own menu system (panel, context menus on desktop and so on), and each menu item that opens a window must open it on the same screen.

GNOME has it almost right.

If you don't have the right hardware, a virtual machine under VirtualBox will probably do the job.
Comment 5 RHEL Product and Program Management 2013-10-13 20:32:19 EDT
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated
in the current release, Red Hat is unable to address this
request at this time.

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