Hello Christopher @penalvch, you're the Jon Skeet of launchpad :-).
Honestly, I don't care about a backport.
The machine is currently running Debian actually. Had I needed Ubuntu, I
would have used 16.04 anyway.
So, I'll mark this as invalid as you request (I would not have
considered "invalid", rather "wontfix").
What's the rationale for "invalid" here?
Thanks.

Title:
Resolution limited to 1024x768
Status in xserver-xorg-video-ati package in Ubuntu:
Invalid
Bug description:
Bug reported with xdiagnose.
# Summary
On installing Ubuntu 13.10 or 14.04 on a NTA3500 nettop with a VGA
monitor HP vs19e (native resolution 1280x1024), a resolution of
1024x768 is obtained.
The bug is not that the correct resolution cannot be obtained at all
(there's a workaround below with xrandr) but about the fact that is is
not automatically selected despite good EDID data available from
monitor.
# Details
Machine has two video output ports: HDMI and DVI.
No monitor is plugged on HDMI.
Monitor used is plugged on DVI with a DVI-to-VGA passive adapter.
The open-source driver is used.
xrandr and graphical tools don't offer more than 1024x768 on this screen.
xrandr output:
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192

Looks like VBE was successful. Have a good day.
# Additional information, comparison
Same monitor was used on various machines, bug only happens on this
machine.
With no change to hardware, when using ATI proprietary driver,
1280x1024 is available by default (no need for a workaround).
# Workaround
A similar problem was reported on
http://askubuntu.com/questions/207716/ubuntu-12-10-resolution-stuck-
at-1024x768-using-open-source-radeon-driver .
The following sequence allows to get a proper resolution with open-
source driver once.
cvt 1280 1024 60
xrandr --newmode "1280x1024_60.00" 109.00 1280 1368 1496 1712 1024 1027
1034 1063 -hsync +vsync
xrandr --addmode VGA-0 1280x1024_60.00
xrandr --output DVI-0 --off --output VGA-0 --mode 1280x1024_60.00
# Offer for help
What can I do to improve Ubuntu so that other users (including me when
I do a clean Ubuntu install in the future) automatically get correct
resolution ?
How to diagnose the reason why the correct resolution as reported by
the monitor is not used by open-source driver ?
Thank you for your attention
