Screen Goes Power Save Mode
I have seen this asked elsewhere but its always something slightly different and doesnt help.

Anyway this time i installed Mandrake 9.2 and i did it through the graphic install and all went well.. Everything seems fine. So then i restarted my pc and tried to boot Mandrake. when its about to boot the screen just goes blank (black) and its like gone into power save mode. It cant be a graphics drivers cause i checked them and they are there. Geforce 4ti 4600.

Im begining to think its my screen. I have a Dell UltraSharp 2000FP.

Any ideas?:newbie:

I think that you have set a too high resolution and/or update frequency for your monitor. When the monitor doesn't find a signal it shuts down.

Try editing your /etc/X11/XF86Config file. I'm not very familiar with Mandrake, so I can't tell you how to do it. Someone else can probably tell how to get to a text mode login.

Good luck!

Okay well i am able to get to the text mode login. How would i edit this file and what do i want it to say?

Hi again!

Have you got emacs installed? First look at which file you have, since there are two alternatives:
~> cd /etc/X11
~> ls -l

You should have either a file called XF86Config or a file called XF86Config-4.

First make a backup copy the file and then edit it:
~> cp XF86Config XF86Config_old
~> emacs XF86Config

The section "Monitor" should look like this:

Section "Monitor"
        Identifier  "Monitor0"
        VendorName  "Monitor Vendor"
        ModelName    "Dell 2000FP"
        HorizSync    31.5 - 80.0
        VertRefresh  56.0 - 76.0
        ModeLine    "1400x1050" 129.0 1400 1464 1656 1960 1050 1051 1054 1100 +hsync +vsync
        ModeLine    "1400x1050" 151.0 1400 1464 1656 1960 1050 1051 1054 1100 +hsync +vsync
        ModeLine    "1400x1050" 162.0 1400 1464 1656 1960 1050 1051 1054 1100 +hsync +vsync
        ModeLine    "1400x1050" 184.0 1400 1464 1656 1960 1050 1051 1054 1100 +hsync +vsync
        Option      "dpms"

Save the file with ctrl-x ctrl-s. Leave emacs with ctrl-x ctrl-c. If you make a mistake, you can leave emacs without saving.

Good luck!

I feel terrible being a complete newb.. but everyone starts off as one. what is emacs?

And is that what i should see.. or what i should make it say.. ?

Hi again!

Sorry, if you had posted this in the newbie section I would have given more detailed instructions (hint about how I try to answer questions in different sections ;) ).

Emacs is a text editor, but never mind. Do like this instead.

I made a reply in this thread about getting a file off the Linux computer and on to a floppy, so that you can edit it elsewhere:

Get your /etc/X11/XF86Config (or XF86Config-4, whichever you have) and post it here.


CrAzY G 01-18-2004 02:24 PM

Will do.. and i will add i just saw my config file. (apparantly i have both the vonfig and config-4 but it uses config-4.. well thats what it said. so ill post config-4 here in a few minutes.

I wonder why there are no 'Modes' lines in your file? I thought they were mandatory...

Try editing your 'Display' sections (all of them) from this:

Subsection "Display"
Depth <whatever value>
Virtual 1280 960

to this:

Subsection "Display"
Depth <...
Modes  "640x480" "800x600" "1024x768" "1280x1024"
Virtual 1280 960

Now, save the file back to where it came from on the Linux computer and start X. You should get to a graphical display in 640*480. Try cycling through the video modes with ctrl-alt-(and the '+' key on the numerical keyboard).

Once you verify that this works, you can put the desired resolution first in the list in the Modes section.

Good luck!

Only e-mail I'm afraid. If you think that it would be more convenient than writing posts here, please do send an e-mail. Do it by clicking on my 'profile' button.
