Should work now.
Please give it a try.
I gave it a try, but it does not work. I am sorry. I have created the
7 output and attached it to this email. I used git clone
git:// to get the
driver. I hope this is the correct repository and branch.
Do I need to use ReducedBlanking, because I only have a single link DVI cable
but I use 1920x1200. I have read that reduced blanking is necessary for this
resolution with such a cable.


(II) Loading /usr/lib64/xorg/modules//
(II) Module radeonhd: vendor="AMD GPG"
compiled for 1.4.0, module version = 0.0.2
Module class: X.Org Video Driver
ABI class: X.Org Video Driver, version 2.0

Ancient version, please try recent git :)

This looks like a reduced blanking mode:
(II) RADEONHD(0): h_active: 1920 h_sync: 1968 h_sync_end 2000 h_blank_end
2080 h_border: 0
(II) RADEONHD(0): v_active: 1200 v_sync: 1203 v_sync_end 1209 v_blanking:
1235 v_border: 0

Monitor setup:

(II) RADEONHD(0): Connector "DUAL_LINK_DVI_I DFP1 CRT2" uses Monitor
Bandwidth: 160MHz
Horizontal timing:
30.0 - 83.0kHz
Vertical timing:
56.0 - 75.0Hz
Allows reduced blanking.

And our driver noticed it too :)

Attached modes:

Desired mode:
Modeline "1920x1200" 154.00 1920 1968 2000 2080 1200 1203 1209
1235 -hsync +vsync
Has a low dotclock, and reduced blanking.

(--) RADEONHD(0): Virtual size is 1920x1200 (pitch 1920)
(**) RADEONHD(0): *Mode "1920x1200": 154.0 MHz, 74.0 kHz, 60.0 Hz
(II) RADEONHD(0): Modeline "1920x1200"x60.0 154.00 1920 1968 2000 2080
1200 1203 1209 1235 -hsync +vsync (74.0 kHz)

Looks ok :)

(II) RADEONHD(0): Setting up "1920x1200" (1920x1200@xxxxxx)


(II) RADEONHD(0): RHDPLLSet: Setting PLL 1 to 154000kHz

It all seems to work.

Can you explain the issue you are seeing? Our driver selects the right
mode, so this cannot be it.
