monitor not working

[Elenril]

Another silly problem from your local computer-destroyer.

I just installed Ubuntu, and I went to the Restricted Device Manager and installed the 3D acceleration driver for my ATI Radeon 9550 graphics card. I restarted my computer (as it prompted me to do).

Now when I boot up my computer, it goes through all the motions of loading Ubuntu, the loading screen comes up with the orange bar, all the white text on the black screen scrolls up that says loading etc... Then my monitor says 'power saving mode', and goes blank.

Does anyone know the cause or how to fix this?

Sounds as though your graphics display is set to a range that you monitor isnt capable of.

Try pressing <CTRL>+<ALT>+F1, then <CTRL>+<ALT>+F7 to switch sessions to 1, then back to 7 (where your default session should be).

See if that helps, let us know.

Sorry, I'm a bit unclear as to the exact point which I press these keys. On the loading Ubuntu screen I pressed ctrl+alt+F1, which made it show this:

Then it just keeps doing its white text on black screen thing, and goes to power saving mode again.

It probably is the frequency, one of the times it showed 'out of range 14mhz/24ghz' or something. But it only did that once and hasn't done it since.

Press it at the prompt that you are seeing there.

It didn't seem to do anything, I fiddled around with xorg.conf, which didn't seem to do anything either, so I used my favourite problem solver: Uninstall, Reinstall!

It seems to be working fine, I'm being extra careful with what I download and install now.

Thanks for your help.

Elenril, Normally when the system is fully booted, you can press the ctrl+alt+F? key to get a non-graphic console (thought it was F1-F8 with one of them being the graphics session). Or on the screen that _should_ be the graphics terminal, you can press ctrl+alt+bkspc to kill the x-server and get a text login.

Just for future reference...
