What I decided to do was upgrade to 12.04 LTS following Steve's advice. I thought for a while that it had gone horribly wrong (screen went awol) but lots of switching off and on again have calmed and sorted it. Hoping it stays that way...
Hope it goes OK :-)
Suspect if I upgrade in 5 years (or less?) I will definitely need a new monitor. (New new not just new to me.)
I would think people are practically giving away traditional-style monitors as everyone wants flat screen, that said, I love flat screen! You might find someone giving one away on Freegle, or Freecycle.
Good luck! :-) Steve
My current one, a fine (imo) LCD monitor, was £20. (Hansol 700Fs - we have a great second hand computer here!) Thing is, I worry that 5 years down the line, the latest Ubuntu won't recognise it.

Most monitors, especially LCD screens, and doubly especially anything with HDMI, should be self describing with an EDID. The EDID includes things like the monitor's name, serial number and list of possible modes. The OS doesn't need to keep a massive list of all known monitors - it just asks for the EDID and usually picks the mode labelled "Preferred".

Right. Houston, we have a Problem. It's just done the awol screen again. :( Switching it off has helped but how do I stop it doing this completely? (A friend did try helping yesterday but couldn't find much.)

A bit of research (reading the manual) and it seems graphics card config using xorg might be useful. How do I find what card I have and what driver it uses?

Hi,
I think Ubuntu has moved on from using XOrg and its config file. I think the first thing to do is use the app that I think is called "Monitors" on the menu, or maybe Display. This should detect the monitor. It will also allow you to set the screen size and refresh rate - a quick google shows me (if I'm correct, should be 1280 x 1024 / 75.0 Hz). If you select the settings and confirm them via the relevant button on that program, it hopefully should remember them for next time.
My LCD monitor has a "Autosense" button which aligns the screen left/righ/up/down etc when use via a VGA cable. Perhaps yours has something similar - it may be worth checking, and pressing it if it has.
When the screen goes AWOL, what happens? Does the screen LED status light change colour? Is there an error message - like Frequency out of range, or something like that, or does it just go blank? I guess I should ask the fundamental question - are all the cables connected tightly and the power light is on when the screen goes AWOL?
Are you connecting via an (modern) DVI (HDMI) cable, or a (old fashioned) VGA cable?
I seem to recall that you can use a program called xrandr (X windows Resize AND Rotate) to check what mode your monitor is in, and force it into a particular resolution. It may be helpful to run xrandr in a terminal and report back on what modes your monitor is in and can support.
If it's not installed, in my old copy of Ubuntu, it's in the x11-xserver-utils package.
Hope this helps. Steve
Certain the screen resolution is OK. (It is now, for example.)

Absolutely certain the screen resolution is OK. (It is now, for example.) It auto configs when I switch it on.

What happens? Well, the graphics get very distorted. The top half of the desktop (not the login screen) is three stripes of my wallpaper, and the lower half either black, white, a mix of both or sometimes pinky orange colour. The pointing device/mouse makes it flash like a strobe light.

Is the spec so I assume that means VGA. The graphics card is.

Sounds to me like the refresh rate is too fast for the monitor, though if the monitor can do 75Hz, I'd be surprised by that. What do others think?
Can you photo it when it happens and post it somewhere, or email me? Alternatively, when it happens, try switching to a console by pressing ctrl-alt-f1 and see if the screen sorts it self out at the text based screen, then press ctrl-alt-f? (6, 7 or 8 - not sure which) to get back to the GUI desktop.

Sounds like it's vga.
Good luck! Steve

Sounds like it could be an intermittent fault with the graphics chip, maybe it only displays these symptoms when the temperature reaches a certain point.
Cheers, BJ
