2407WFP and UNIX/BSD/Linux (XFree86/Xorg)

Question

Hi,

just got my 2407WFP yesterday. Attached on a MacMini G4 with Radeon 9200 DVI.

MacOSX runs fine.

Now I'd like to get it up under NetBSD/macppc 3.99.21 (let's say "get it running with X",
NetBSD/Linux should not matter).

Now the display should do 1920x1200 60Hz @ 154 MHz only?

Can anyone give me a valid X*-config and/or at least a modeline for this?
X seems to construct a modeline, but the 2407 says "out of range" :-(

I forced 1920x1200. Anyway, it does not display *ANY* resolution (either goes into
powersave or "out of range").

Thanks
Flo

This should actually be easy... you do need to have your horiz and vert refresh ranges handy and then you can configure the /etc/X11/xorg.conf file to work with either NVidia or ATI openGL drivers.

Let me know if you need more specifics, but depending on what Linux distro you use, it should have instructions for setting up the above file.

I was able to get a ModeLine for my 2007FPW by starting X using a more detailed logging mode. I believe the option was "-logverbose 5" though that might be slightly off. Anyway, once you start X like that, just check your log file and it should have all the information you need in there. My 2007FPW has the correct information in the EDID, it just doesn't actually have the right resolution enabled for some reason. (And the NVIDIA driver's attempt to auto-determine it weren't successful either.)

Also, you might run into the same problem as me: the monitor goes into power saving mode when you start X or when switching desktops (Ctrl. + Alt. + F#). If this is the case, try leaving it idle long enough for X to activate the power saving features, then move the mouse or press a key. That will bring the monitor to life for me. (It's certainly a pain though. Any other workarounds or solutions would be greatly appreciated.)

Hi

I haven't been able to get the 2407WFP working at 1920x1200 as an external monitor (VGA) for a Thinkpad T43p under RHEL4 (2.6.14). The videocard is an ATI FireGL M24 GL.

The problem seems to be that the default "1920x1200" mode has "hsync out of range". So I added a ModeLine to match this:
(II) RADEON(0): Supported additional Video Mode:
(II) RADEON(0): clock: 154.0 MHz Image Size: 519 x 324 mm
(II) RADEON(0): h_active: 1920 h_sync: 1968 h_sync_end 2000 h_blank_end 2080 h_border: 0
(II) RADEON(0): v_active: 1200 v_sync: 1203 v_sync_end 1209 v_blanking: 1235 v_border: 0

ModeLine "1920x1200@60" 154.0 1920 1968 2000 2080 1200 1203 1209 1235 +hsync -vsync

However, I still get "Mode "1920x1200@60" is not a supported mode for CRT2" and as a result I don't get the 1920x1200 resolution. Instead it dumps me into "1280x1024" on a 1920x1200 virtual desktop.

I noticed that 154.0e6/(2080*1235) isn't exactly equal to 60MHz, so I also tried 154.128 for the pixel clock, i.e.

ModeLine "1920x1200@60" 154.128 1920 1968 2000 2080 1200 1203 1209 1235 +hsync -vsync,

but that doesn't work either, same problem.

I just can't figure out how to get it configured correctly.

Any help, or a working xorg.conf file, would be greatly appreciated!

P.S. I'm happy to supply my xorg.conf or Xorg.0.log file.
