monitor problems

[chrispap]

Hi everyone,
I just installed the latest version of Ubuntu on an external disk(500gb) giving 12gb to Ubuntu.
After the installation process finished I did reboot.When BIOS loaded instead of the Ubuntu boot screen a message from the monitor presented like this:
information
out of range
93.0kHz/58Hz
So I suppose that there must be a monitor problem or something.
I would appreciate any kind of help.
Thank's

Ubuntu is putting out a mode that the screen can't handle; I've never had to deal with that, but I'll have a crack. It probably won't help, but swap out the monitor cable if you have one spare.

Failing the above, we can try manually configuring xorg.conf, to specify your monitor's capabilities. Post the make and model of your graphics card and monitor, and we'll take it from there.

It wont help to try and configure xorg.conf as its not getting that far. Thats a hardware problem during boot either caused by a bad cable, inline adaptor , external splitter or the video card itself (if you have added one other than the onboard video)
You need to post your computer setup or use the above info to find your problem.

My graphics card is nvidia G73 Geforce 7600GT, my monitor is 17" Sony SDM-S73/H TC003, my motherboard is Albatron Socket 478 Mainboard PX848PV Series and my cpu is Intel Pentium 4 2.60GHz.I also have 1.50Gb ram.

I assume that you had graphics during the install, or another OS - so I'm going to work on the basis that it is a config problem (not your doing).

Boot with the live/install CD, and when you get to the desktop, access your drive using nautilus, or whatever the file manager currently is. Locate this file, if it exists:


/etc/X11/xorg.conf

If it does not exist, simply open gedit and add the config below; save it using the name and path above.


Section "Monitor"
Identifier "Monitor0"
VendorName "Sony"
ModelName "SDM-S73"
HorizSync 28 - 80
VertRefresh 48 - 75
EndSection

Section "Device"
Identifier "Device0"
Driver "nouveau"
VendorName "Geforce 7600GT"
EndSection

Section "Screen"
Identifier "Screen0"
Device "Device0"
Monitor "Monitor0"
SubSection "Display"
Depth 24
Modes "1280x1024"
EndSubSection
EndSection

If the above does not work, use this:


/etc/X11/xorg.conf

If it does not exist, simply open gedit and add the config below; save it using the name and path above.


Section "Monitor"
Identifier "Monitor0"
VendorName "Sony"
ModelName "SDM-S73"
HorizSync 28 - 80
VertRefresh 48 - 75
Modeline "1280x1024_60.00" 109.00 1280 1368 1496 1712 1024 1027 1034 1063 -hsync +vsync

I've referenced the open nvidia driver, but once you're up and running, you can always use the proprietary driver (hardware acceleration).

I went to that location and the file xorg.config does not exist so I opened gedit and tried to create it, but I cannot save it there because I don't have the permission.

[Grenage]

My mistake; I wasn't sure if it would have a permission issue with the live CD. You can use this from a terminal:


sudo gedit

That will open gedit with root rights. Make sure it's /etc/X11/ on your computer drive, and not /etc/X11/ on the liveCD, or it won't help. ;)

[chrispap]

Unfortunately, there was no success at all. The xorg.config file didn't exist but even after I created it the problem remains the same. I wonder if you wanted a video of my computer booting to see the problem yourself. Is there any possibility to be a grub problem, because after my bios boot from the disk containing Ubuntu there is nothing at all showing up but that black screen with the monitor message into.
Thanks for your help,
Chris

Hi Chris, sorry about the slow reply; My home PC decided to die, and I ended up 'fixing' it with a claw hammer.

After the BIOS, you should be able to view the grup menu by holding down shift; does grub get displayed, or is the screen still blank there? Did you try adding the modeline?

[chrispap]

Here is a video of my computer booting:

As you can see there is no grub menu or anything at all after the bios load, but only that black sreen with the monitor's message into. When this happens the computer does not respond to anything, but to reboot from the button on the case.

[dino99]

to get the grub menu (hidden by default on single OS system): at bios end process hold "shift" key down

then select the second line: recovery mode, then netboot

run:
sudo rm /etc/X11/xorg.conf
sudo nvidia-xconfig -s

then reboot

After watching your video I think this issue has nothing to do with xorg.conf...sorry.

I would suggest to set a vga boot option,as described here:

http://ubuntuforums.org/showpost.php?p=1938284&postcount=2

would start with vga=771.....
"interrupt GRUB" means pressing "e"

[Grenage]

It does seem less likely, I agree. What I find curious, is that if the resolution problem was for grub alone, wouldn't the display kick in later on?

I've never had a grub resolution problem, so this is mere speculation.

[chrispap]

I discovered that if I press enter when I am on the black screen, after some time I get a message that tells me that my hardware does not support Unity and then Ubuntu environment shows up. After that I get a message which tells me that I have to install a nvidia driver to have Unity working properly, but when I am trying to install that driver or just install a program, I always get a message to give an authorization code which I don't know. How can I find it? Have I declared it during the installation process?

[realzippy]

Yes,you have been asked for a password when installing.And confirmed it typing it twice...

[chrispap]

Finally, I fixed it!:D
I installed all the drivers and the updates available and then I changed the resolution and the color bits with startup manager.
I would like to thank you all so much for your help,
chrispap

Fine.
So you might set thread as solved ? (ThreadTools)
Have fun..
