System - a reference lucid system from 10.04 lucid CD downloaded late
July, all updates, no tweaks, mostly working to local servers but
inevitably with a bit of local work accumulation.
Following the latest update which included an X- package, my screen
resolution is now limited to 800x600 - which many websites and many
Ubuntu utilities no not support graciously.
Previously (lucid release CD with all updates except the last batch) I
chose 1024x768 from a list that included several higher resolutions, all
of which worked on my MBO e-tron 770 monitor (17 inch CRT, 'Unknown' on
the System-Preferences-Monitors utility)
If really necessary I can reinstall and not update to get earlier
diagnostics but I would want to be sure I am getting the right stuff for
you, and that I need to, before tearing this system down.
xdpyinfo includes the following - clearly not right for a 17 inch
monitor:
screen #0:
dimensions: 800x600 pixels (212x159 millimeters)
resolution: 96x96 dots per inch
depths (7): 24, 1, 4, 8, 15, 16, 32
root window id: 0x102
depth of root window: 24 planes
number of colormaps: minimum 1, maximum 1
default colormap: 0x20
default number of colormap cells: 256
preallocated pixels: black 0, white 16777215
OpenOffice must get its screen information from somewhere else - its
documents are displayed approximately 20% oversize.
