Title:
Dual displays are visually corrupt after boot/login of Kubuntu 13.04
Status in “xorg” package in Ubuntu:
New
Bug description:
I have installed Kubuntu 13.04 on a system with this hardware:
ASUS P8Z77-M Pro mother-board
i5-3550 CPU with integrated HD Graphics 2500 (Intel Corporation Ivy
Bridge Graphics Controller (rev 09))
16GB RAM
1600x1200 DVI monitor (LG L2000C)
1920x1080 HDMI monitor (ASUS VH242H)
The system boots correctly through the login, after which I see this
(photograph):

A strip from the right side of the HDMI display is showing on the left side
of the screen.
A screenshot, giving no indication of any problem, shows what should be
visible:

Then I launch "System Settings" > "Display and Monitor", disable the
HDMI monitor, click the Apply button, and wait a few seconds for the
system to reset the display. Then I enable the HDMI monitor, again
click the Apply button and wait for the display to be reset. At this
time everything works fine ----- until the next boot, or logoff/logon,
when I have to repeat the procedure.
I installed a 3.4.6 kernel in Kubuntu 13.04. When booting from that
kernel, there is no problem with the display. When the HDMI monitor is
connected as VGA, there is no problem. When the HDMI monitor is the
only display connected, there is no problem. I do see the same problem
with Linux Mint 15. The problem does not show in a virtual machine or
when booting from the live disk.
If it helps, here are links to the Xorg logs after booting each kernel:
