Maybe X isn't getting the correct resolution from the monitor. Check the
xorg log file and see if that helps.
The Xorg log file ( /var/log/Xorg.0.log ) shows no relevant errors and
only a few items that seem to relate to the resolution. e.g.
[ 101.814] Mode: 143 (1400x1050)
...
[ 101.814] Mode: 145 (1400x1050)
...
[ 101.815] *Mode: 146 (1400x1050)
...
I do see one hopeful piece?
$ grep -i modeline /var/log/Xorg.0.log
[ 23.821] (II) VESA(0): Printing DDC gathered Modelines:
[ 23.821] (II) VESA(0): Modeline "1680x1050"x0.0

You may need to set a modeline config in an xorg.conf file.
The wiki ( https://wiki.debian.org/Xorg ) mentions to run
cd /etc/X11/
Xorg -configure
I've tried that with X turned off as well as from single-user mode and
gotten only a core dump and a skeletal xorg.conf then appears in /root.
I suppose I add the modeline info to that.
Where would I find the official instructions about creating a proper
modeline for the hardware I have?
#lspci |grep VGA
01:00.0 VGA compatible controller: Advanced Micro Devices,
Inc. [AMD/ATI] Seymour [Radeon HD 6400M/7400M Series]
Have you googled this issue? i.e using "monitor model linux resolution"
Extensively over the last two days.
