I can't get my laptop's displayport output to drive my monitor, using the
free ati driver. It does work on the legacy driver, from ATI, however, that
only works on X <= 1.12, which is no fun to be stuck with, as no current
distro ships old versions of X. I have a 27 inch dell monitor, so using
HDMI is not great option, as it can't drive a high enough resolution to look
sharp, as I want 2560 x 1440.

title="NEW --- - No video output via DisplayPort on Mobility HD 4670."
href="show_bug.cgi?id=45291">Bug 45291</a> is basically the same problem, and I've updated it to include
my hardware as well.
My monitor is a :DELL U2711
Video card: Mobility Radeon HD 4650
Laptop: Dell Studio 1747
This bug has a boot with drm.debug=6 attached, and as much other debugging
infomation as I could find.
I am happy to work fairly closely on this, if someone has ideas or information
they need me to collect.</pre>
