When Linux starts monitor dims (Power Saving Mode)


Hello Everyone,

I have a problem when try to start Ubuntu Linux 10.04.
On my PC, i have a dual boot, Windows 7 64-bit and Ubuntu Linux 10.04 64-bit. When selecting Linux on Grub, (see picture) http://img404.imageshack.us/img404/742/img6699x.jpg
afther a few seconds, my the monitor (system?) get in power safe mode.

I had issue during installation 10.04, witch i solve like this:

1. Press F6 to open the other menu options.
2. This opens this new menu ... it's useless to us. So now close it!
3. We did this so that the command options show up near the bottom of the screen. Press tab to access these options.
4. Press space ones (to make some space) and enter the following:-xforcevesa
5. Press enter to boot

PS specification:
graphics card is NVIDIA GeForce 9600 GT
monitor LG W2242 (Analog) type 22 "LCD (WSXGA +)
resolution 1680 x 1050.

How to solve the problem?


Note:
Beginner in the Linux world, and my English is very bad.

It doesn't stay in power save mode does it? Eventually it will turn back on and you will see the log in screen. Is that correct?

If you want to change it you may have to change the monitor settings to disable power save mode, if that's possible.

Your monitor will have some buttons somewhere. One will say something like "Menu" or Settings". Press that and look for power save settings. Maybe you can make it wait longer before it goes into power save mode. Maybe it is only on/off. Maybe you can't disable power save mode.

That's all that I can think of.

The reason that this happens is that when Linux is booting it changes the video settings. When this happens the video card stops sending a video signal to the monitor for a moment. The monitor thinks that the computer has turned off and goes into power save mode.

As far as I know the only thing that you could do to stop that would be to stop Linux from setting the video card from it's power on default. You probably would not want to do that. Setting the video card mode is part of making the desktop look its best.
