works well with xorg-x11-server-Xorg-1.15.0-16.el6 & xorg-x11-drv-fbdev-0.4.3-15-el6 does not work with xorg-x11-server-Xorg-1.15.0-18.el6 & xorg-x11-drv-fbdev-0.4.3-16-el6
Hi Adam, It happened on the RHEL6.6 running as Hyper-V guest. If needed, we Virt-QE would like to setup related ENV for you. It is an important and urgent issue. With the bug, our customers will no use the GUI at all. Could you help to have a look at the issue? Could i know you plan about it? Thanks,

(In reply to Tomas Pelka from comment #6) > > *** This bug has been marked as a duplicate of bug 1127104 *** Hi Tomas, This is a regression problem. It works well on xorg-x11-server-Xorg-1.15.0-16.el6, while it does not work on xorg-x11-server-Xorg-1.15.0-18.el6. The bug 1127104 is fixed on xorg-x11-server-1.15.0-17.el6. In my opinion, it is not a duplicate of bug 1127104. Could you please help to have a look at the issue? We'd like to setup test ENV for you.
