I don't usually set it, but I think that's mostly because the only time I have to specify settings myself is when the EDID or whatever isn't working properly. Monitors' support for this mode-gathering stuff seems to vary inversely with it's age. Many of the older ones I have refuse to help X configure them at all. > > PS: Can we please try to trim the emails down a little?

I am not familiar with ddcxinfo-knoppix, but it probably lists modelines from up to 3 different sources. The graphics card can supply a list of available resolutions -- that's where [EMAIL PROTECTED] came from I bet. The monitor's refresh rates can also be used to extrapolate possible modelines -- I don't know how to do this, but aside from this program, there are websites that can do so for you. Finally, the VESA standard defines what would likely be called generic settings that are supported by any VESA-compliant monitor and graphics card (just about all of them you can still physically connect to new computers, nowadays). These standard values are a good place to start, as your monitor should work for them, and you should be able to find one ([EMAIL PROTECTED], maybe) that your monitor supports and that looks nice and doesn't flicker too much, and performs well on your hardware. the Modes line is meant to be a list of modeline names, so you may or may not need the @70 part depending on where the modeline came from. the X logs should list many modelines which X came up with after probing the hardware, and you probably want to use a name from the desired one of these. Have you tried looking up online and entering the refresh rates manually? I highly recommend doing so. Best of luck, dan. -- gentoo-user@gentoo.org mailing list
