I'm a Dapper user looking to migrate to Hardy 8.04.1. I'm confused by the Hardy screen resolution autodetect & how to work around it.
Symptom: Desktop is larger than physical screen. Can't see top or bottom bars. Can't figure out how to scroll or drag desktop to see top or bottom (in order to run screen tool). Editing xorg.conf and restarting X does not help. Tried sudo dpkg-reconfigure -phigh xserver-xorg and it didn't help.
Question: How do I cope in a livecd/liveusb environment? How do I work around the new hardware autodetect permanently for an install?
Background: I've always had difficulty with Ubuntu autodetect because I use a Belken PS/2 KVM switch. Works fine with most Linux scrren autodetect, but has always confused Ubuntu. I run Dapper with hand-edited xorg.conf.
Monitor works fine with xorg.conf HorizSync 28-51, VertRefresh 43-60, Display (SubSection) Depth 1 and Modes "1024x768" "800x600" "640x480"
Monitor is Amphion CM1722PF, bought at a Circuit City loss leader sale. Circuit City gave specs on (now defunct) web page as: "Recommended resolution 1280 x 1024," "Horizontal scanning frequency 30-72KHz," "Vertical scanning frequency 50-135Hz." Running sudo ddcprobe | grep monitorrange gives 30-70 and 50-135.
I've googled and browsed, so I hope that this isn't too obvious...
