<pre>I'm having the same issue, using an outboard DisplayPort to Dual-Link DVI-D
adapter.
Adapter: Accell B087B-007B

Computer is a Dell Optiplex 990 USFF ("ultra small form factor"), CPU is
i7-2600S, using CPU graphics (HD2000 I think?). OS is Fedora 18 x86_64, fully
up-to-date. More system info:
<a href="http://paste.fedoraproject.org/12071/45046136/">http://paste.fedoraproject.org/12071/45046136/</a>
For whatever it's worth, Windows 7 sees the full resolution without a problem.
I'm pretty sure that grub sees it correctly as well.
If I connect this computer directly to the monitor using a DisplayPort cable,
then it works fine. (I prefer to use the DL DVI-D so I can use my KVM switch.)
It might be worth noting that Luke originally filed a downstream bug:
<a href="https://bugzilla.redhat.com/show_bug.cgi?id=842412">https://bugzilla.redhat.com/show_bug.cgi?id=842412</a>
Not much more information there, but it can't hurt to have them linked.
As I noted in that bug, and as others mentioned elsewhere in this bug, I can
work past the erorr by using xrandr directly:
xrandr --newmode '2560x1440_0.0' 241.50 2560 2608 2640 2720 1440 1443 1448
1481 +hsync -vsync
xrandr --addmode DP1 '2560x1440_0.0'
Is there any info I can provide to help fix this?
Thanks,
Tony</pre>
