actually, I have both. the KVM dates from 2010 and came with four cables and eight plugs. > If you don't know what those are, see this page: > > https://en.wikipedia.org/wiki/File:DVI_Connector_Types.svg > > Most DVI monitor cables have a DVI-D dual link plug on them, but > anything matching those patterns is proof positive of DVI. > > VGA connectors looks like this: > > https://en.wikipedia.org/wiki/File:Vga-cable.jpg > > Anyhow, the point is if you're using a DVI connector, X will be able to > query the monitor and find out its preferred resolution etc. > automatically.

I could ssh to<-> from, but not watch it boot. So I finally decided it was time to buys another Dell, new. somebody gave me a used Dell dual. my server is a new dual from '09. used and refurb'd and home-brew is not the optimal way. so my tech said he would look for the best Dell quad he could find, and after 6 weeeks he brought over the 3010. [fact: this chap is self-taught. but he got me a new kvm and blindly pluged things together.]] whether the 3010 has ye-olden VGA jack =plus= the DVI, I dont know. my guess is that the technician knows the diff. nutshell, looks like whatever ghaphic chipset the computer had maxes out a 5:4 screen-size ratio. I =will= try adding the mode line info. thanks, gary > Cheers, > > Matthew > > -- > Dr Matthew J Seaman MA, D.Phil. > PGP: http://www.infracaninophile.co.uk/pgpkey > > -- Gary Kline kl...@thought.org http://www.thought.org Public Service Unix Twenty-six years of service to the Unix community. _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
