*Even if you don't have exactly the same hardware, this thread will help you out with your cinema display problems*
I've had quite a difficult time diagnosing my problems relating to getting my Cinema display to work properly. I wasn't getting anything from it... the screen was blank or black. I couldn't see anything from the BIOS to X11. It sucked. After hours of trying to find someone else that's had my same problem, I found a few relevant posts that helped a ton to debug my problem:
EDID information: http://www.nvnews.net/vbulletin/showthread.php?t=53129
DVI basics (connector/interface help): http://graphics.tomshardware.com/graphic/20041129/tft_connection-01.html
-------------------------
- THE BOTTOM LINE -
-------------------------
To create the appropriate modeline do the following:
1) from the terminal start X with the following command: | Code: | | startx -- -logverbose 5 |
2) check the X logs for EDID information: | Code: | | less /var/log/Xorg.0.log |
3) from the following example (taken from the EDID link above) that breaks down a Modeline, gather the necessary information from the EDID section in the log file and create your own Modeline: | Quote: | Modeline "1680x1050" 119.00 1680 1728 1760 1840 1050 1053 1059 1080
The first real number (119.00) is the dot pixel clock, which is given in the log line
(II) NVIDIA(0): clock: 119.0 MHz Image Size: 433 x 270 mm
The first integer number (1680) is the horizontal number of pixels, hdisp, as given in the log line
(II) NVIDIA(0): h_active: 1680 h_sync: 1728 h_sync_end 1760 h_blank_end 1840
The second (1728) is hsyncstart. The third integer (1760) is hsyncend. The fourth integer is htotal.
The fifth integer (1050) is the vertical number of pixels, vdisp, as given in the log line
(II) NVIDIA(0): v_active: 1050 v_sync: 1053 v_sync_end 1059 v_blanking: 1080
The sixth integer (1053) is vsyncstart. The seventh integer (1059) is vsyncend. The eighth integer (1080) is vtotal. |
4) My xorg.conf file looks like this: | Code: | # **********************************************************************

As for the Monitor section of the xorg.conf file, I'm not sure what the +hsync and +vsync parameters do on the Modeline, so maybe someone can enlighten me on that fact.
One problem I ran into is that my graphics cards that I used (a Asus Geforce FX 5200 and the eVGA Geforce FX 5200) were not powerful enough to handle the monitor. That's why the screen was black/blank. I noticed that the pixel clock rate maxed out at 135MHz but the Modeline needed 150MHz, so obviously there was some inconsistency somewhere. Anyway, I got a Geforce 6200 now and it worked right off the bat... I've heard the Geforce FX 5900's work well too.
If there's more to add, please feel free to post... if I come up with anything more, I'll post something too.
Thanks,
