Comment 3 RHEL Program Management 2011-10-18 18:40:08 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.

Please attach the output from 'intel_reg_dumper' from the affected setup.  This command is available in the intel-gpu-tools package.

Comment 7 Adam Jackson 2012-05-17 19:57:24 UTC

Do you still see this with 6.3?

This appears to correspond to the following commit in upstream DRM:

    drm/i915: properly alternate between DVI and HDMI
    
    This solves problems that happen when you alternate between HDMI and
    DVI on the same port. I can reproduce these problems using DP->HDMI
    and DP->DVI adapters on a DP port.
    
    When you first plug HDMI and then plug DVI, you need to stop sending
    DIPs, even if the port is in DVI mode (see the HDMI register spec). If
    you don't stop sending DIPs, you'll see a pink vertical line on the
    left side of the screen, some modes will give you a black screen, some
    modes won't work correctly. [...]

This change is included in the DRM rebase series posted to rhkernel.

Lukas, please attach the output from 'xrandr --properties' with the affected monitor connected.

I still can't proceed without this.

That was a year ago, this must not be urgent.  Closing.  Please do retest this scenario with RHEL 6.6 and 7.0 so we can either verify that this has been fixed, or create a bug to fix it.
