SuSE 10.0 and Samsung SyncMaster - Unable to get into 1680x1050 mode
 

I added this Syncmaster 215tw after installing SuSE. When configuring in sax2, I have to select -->lcd and and the 1680x1050 resolution, because there's no option for "Syncmaster 215TW".

But in the KDE Control Panel, 1280x1024 is the highest resolution available.

It is an intel 945 graphics, Samsung Syncmaster 215tw.

I've been unable, after searching through lots of posts, to determine what, exactly, is the problem.

My xorg.conf is listed below for informational purpose. I would hate to have to modify the xorg.conf file, but really just want to know how I can get the monitor to appear in the KDE Control Panel, i.e., to be recognized, which I suspect it would be had I added the monitor _before_ installing SuSE.

Thanks,
TR

Why? To fix this, you'll either modify it manually, or using something like xorgconfig.

With an LCD, there's little point in having all those options. They are best at their native resolution.

I would use gtf to generate ONE modeline (for 60Hz). Here's what it gives me:
Modeline "1680x1050_60.00" 147.14 1680 1784 1968 2256 1050 1051 1054 1087 -HSync +Vsync
One article I found recommends editing out the stuff in bold.....

Here's how your xorg.conf might wind up (extra junk removed)

Identifier "Monitor[0]"
ModelName "xxx"
VendorName "yyy"
Modeline "1680x1050_60" 147.14 1680 1784 1968 2256 1050 1051 1054 1087 -HSync +Vsync

(Delete Section "Modes")

You might need to use a package called 915resolution to patch the video bios. Instructions with the package are straight forward.
