Yours seem to not be doing that. Perhaps you have an outdated version of Edubuntu (or a too-new version that has bugs). Or maybe you're just unlucky. Either way, you can manually specify the drivers and resolution in lts.conf.
I think Edubuntu keeps that file in /var/lib/tftpboot, but I'm not sure. I also think you need to run another command after editing lts.conf (this is related to Edubuntu using a squashed image instead of NFS, like my Debian system). Somebody on this list is sure to know what that command is -- I can't remember it. Anyway, you'll want to run 'man lts.conf' to get some details on how that file is structured. You'll probably want to include something like this for your problem clients: XSERVER = vesa X_MODE_0 = 1280x1024 vesa is a good xserver value to start with, because it usually works. It is slower than others, so once you get things working you may want to try other values. You can specify these settings as default or per-client (by MAC address or by hostname, I believe). -Rob ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
