Bug 33549 – Specific modeline does not work with buildin matrox driver, but works with the driver from matrox

• Product: Gentoo Linux
• Status: RESOLVED WONTFIX

[Description Klaus S. Madsen 2003-11-15 04:29:14 UTC]

I have recently switched to a DVI connected screen. Therefore my Matrox card needed to be 
configured to use the correct mode. Looking at the I2C output, I determined that it should use 
the following modeline: 
 
ModeLine "1280x1024" 108.00 1280 1328 1440 1688 1024 1025 1028 1066 +hsync +vsync 
 
This also corresponds with what Windows is using, both according to the Matrox tools, and 
according to http://www.entechtaiwan.com/files/moninfo.exe. 
 
I could see that X was using the correct modeline from the output of /var/log/XFree86.0.log, but 
when X started, my monitor just showed "Signal out of bounds". 
 
I then installed the drivers available from ftp://ftp.matrox.com/pub/mga/archive/linux/2003/
mgadrivers-3.0.tgz, by running the install.sh script included in the package. When I started X 
again, everything worked fine. 
 
So it seems that the driver included in X does not program the card correctly.

Why is it that you want to set a modeline? Isn't giving it your horizontal and vertical sync rates good enough?

[Comment 3 Klaus S. Madsen 2003-11-15 14:41:26 UTC]

Well, it is enough to give the sync rates. Then X determines that the modeline should be the same as the one that I have specified, and the end result is the same.

If things aren't over-specified, it works fine.
