Thanks.

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

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.
