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.)
Bev.
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
