Sounds like a 19" Polaroid TV I have, except I got mine broken but free, and fixed it
by replacing bad caps. Could be your Envision and my Polaroid came out of the same
manufacturing plant. :-p Even though specs[1] claim it is native 1440x900, xrandr of
every version tried, which is many, inexplicably for a widescreen display reports
1280x1024 as native. Its specs actually list supported modes as high as 1792x1344,
same as its EDID[2], rather unusual I think for so small a display.
Xorg still offers the option to configure a display via xorg.conf, optionally in
/etc/X11/xorg.conf.d/, besides the xrandr options and for some DEs settings options.
If you’re not familiar with configuring an xorg.conf file manually or with SaX3, you
can use http://fm.no-ip.com/Share/xorg.conf-minimal-EDID-workaround as a template
almost as is. The only change you need to make is to uncomment the PreferredMode line
with 1440x900 on it. All commented lines can be deleted, and if you want you can
split it into separate files in xorg.conf.d/ to replace the templates openSUSE
installation put there.
