X_HORIZSYNC=30-100 -- no good X_VERTREFRESH=60 -- no good. Here are some snippets from Xorg.7.log that may be interesting. I'm not sure what to make of them.
(II) RADEON(0): Supported Future Video Modes: (II) RADEON(0): #0: hsize: 1024 vsize 768 refresh: 60 vid: 16481 and, (II) RADEON(0): Output VGA-0 connected (II) RADEON(0): Using user preference for initial modes (II) RADEON(0): Output VGA-0 using initial mode 1024x768 after xf86InitialConfiguration and, [config/dbus] couldn't take over org.x.config: org.freedesktop.DBus.Error.AccessDenied (Connection ":1.6" is not allowed to own the service "org.x.config.display7" due to security policies in the configuration file) It appears to me that Xorg claims to be using 1024x...@60hz, but I can't believe it, because that monitor will display 1024x768, just not when connected to a booting tc. I'm going to start comparing the log from a boot with video to one with no video. There must be some clues there. db On Tue, Sep 8, 2009 at 10:10 AM, Gideon Romm<[email protected]> wrote: > David, > > You want a broader range for hsync, not narrower.
