/var/log/XFree86.0.log indicates that the screen has been set to 75
x 75 DPI. i need this to be 96 DPI. where can i edit this? it is
not in the XF86Config file.
also, if i try to
fbset -g 1280 1024 1280 1024 16
then the monitor no longer gets signal, like it is a video card
issue. if the monitor does not support the output resolution, it
will go black with a floating message: unsupported resolution. the
ATI128 worked well under YDL2.0 at 1280x1024, so i am not sure why i
can not fbset 1280x1024.
i have tried to run dexter.py to put in a new monitor config. the H
and V refresh rates are saved to XF86Config-4, the output shows a Gtk
error, and the monitor setting does not change.
also, the only choices the system has for modes are all 1280x1024.
in fact, it is displaying 1280x1024, but at 75 DPI, so that what i
see on the screen is more like 1024x768, with the rest off the
display. i can "scroll" to the undisplayed part, but is not really
usable in this way.
