Black Screen - Out Of Range - First installation


Hello,


I've installed Linux for the first time today (Mandriva Linux 2007 Free Spring). While installing mandriva I was able to choose which screen resoltion I want, so I went ahead and selected 1440x900, as this is the same resolution I use in windwos and the recommend resolution for this specific screen. (IIyama E1900WS).

Now when I want to boot in mandriva, after all the code passes by in splash=verbose mode, I just get a black screen saying out of range. I had tried using VGA=791 in GRUB but that also gave me a black screen. I read somewhere that 791 would be 1024x786, so my screen is definitly capable of displaying it. My monitor runs in windows at 1440x900 @ 75mhz.

I've got a Nvidia Gforce 7600gt Pci-e. Are there any other commands I can use in GRUB to switch resolutions? Also why would the screen go blank if the resolution is supported by my screen, could it be a graphic card problem?

Any help very much welcome, please note this is my first time with Linux so It might take me a bit to understand a few things! Plain english would be appreciated

Thanks

By default, Mandriva provides Open Source Software. This includes the drivers for your graphics adapter and your display. These Open Source drivers are developed without the device specifications from the manufacturer and may not fully support the capabilities of your hardware. Proprietary drivers packaged for use with Mandriva Linux are available from the Internet.

First things first, lets get the GUI operational. When you boot up Mandriva, do you see a text based login? If you do, log in as root and enter
Code:
XFdrake
Select a more conservative resolution (perhaps 1024x768) and save your changes. When this is finished, log out with the key combination CTRL+D. Login as a regular user and start the GUI with
Code:
startx
To gain access to the proprietary drivers for your graphics card as well as the full range of software packaged for use with Mandriva Linux, you should configure the Mandriva Package Manager /urpmi to use the Internet Software Media Sources located on the Mandriva ftp mirror nearest your global location by following the dierction at Easy URPMI. I have written an article to help others better understand this process on my LQ Blog.

HTH,

thanks for the reply, well I don't see a text based login - however I found out that by pressing crtl+alt+f2 I can view the text based login. I tried XFdrake, setting the Vertical Sync and Horizontal Sync for the screen, setting the resolution to something like 1024x768 and then choose Test and it did work.

But startx does not work, it says the server is running already, so i rebooted and did the same procedure again, crtl+alt+f2 and root login then XFdrake, but now the resolutions won't work at all. I checked that everything is the same as before the reboot but if I click on test, no matter what low/high resolution I choose I get the out of range error now as well with XFdrake.

Also before your reply, I had looked up a few vga commands, and when I used vga=normal I was also able to login via the GUI (for the first and only time), so I thought everything was ok now, changed resolution to something low inside mandriva, had the desktop there and everything. Now when I use vga=normal I also get the out of range thing. It's weird, some commands work for the one time only and then if I use them again they don't work. When I was on the desktop and changed the resolution to 1440x900 the screen was cut of half way, it only allowed me to choose a refresh rate of 60hz but my flatscreen supports 75hz at that resolution (maybe thats why its half way cut off), so while I was in linux, I could only run at 1280x760 resolution but it looked really bad/big/blurry.


It seems a bit frustrating, not being able to simply get a monitor working on linux without going through so much hassle.

EDIT: also I'm not able to connect to the internet yet, my USB wifi stick is found but can't find the proper drivers for it, so I booted back to XP to look up some ways to solve this and wrote them down, but now that I can't even go back to linux anymore I'm not able to test them to see if I can get the USB wifi stick to work.

Please post the contents of /etc/x11/xorg.conf as well as /boot/grub/menu.lst

With this information I or someone here may be able to be of greater help.

Just a tip, when you do get the gui to work again, do not change it until you have rebooted a few times.

This will make sure the settings have been saved and configured correctly.

XFdrake or drakxconf will save the settings for you, but don make too many changes at one boot.

You should not have to set the config every time you start mandy, also try not to use the boot loader to solve your problems for the long term, afaik, it's for trouble shooting, as you have used it, but you need to make sure it will boot after the changes ("look mum, no hands).

Mandy, like other distros really does work by it's self. Better than XP :~ !

cheers, and welcome to LQ, Glenn

thanks for the advice guys,

thanks to ernie I was able to access the GUI, I went ahead and booted in fail-safe mode and there it seem to work then. Before hand I just booted normally and therefor had problems with acccessing the GUI etc..

I think I was able to fix it, did a bit of google research yesterday night and found a few sites mentioning the x86config and xorg.conf files, so I had a look at them and edited them the way I wanted it to be. Only problem I have at the moment is that my screen runs at 1440x900 @ 60hz at startup (half the screen is cut off) but once I'm on the desktop I can change it to 75hz (I added this option in xorg.conf) and then the screen is not cut off half way anymore, however everytime I reboot the desktop is at 60hz again. Not sure how to make it so it boots with 75hz without having to change it everytime I boot. Also I edited the GRUB file and removed the vga=791 option which is there by default, once that was removed I could access the GUI.

Now I just need to find a way to get my USB wlan to work and then I'm ready to roll.

When you say flat screen, is that a crt monitor or the newer type of lcd type panel?

Just in case, My flat panel runs at 60Hz by default, but I change it to 50 Hz(more in sync with Australian power standards). This way the graphics card is not working to set a refresh rate and resolution when only the resolution(size) is required. lcd panels don't flicker at low res.

Also, the OS may be picking up the refresh rate from the monitors chip, are there any buttons on the front you can set to modify the refresh rate?

Perhaps you may trick the monitor to see your OS refresh by pulling the power for the monitor, then starting Mandriva. Once a few seconds have passed(long enough to get to the login screen, at least)maybe a minute for some systems, plug the power back in for the monitor. If it has any inteligence it should pick up the os resolution and refresh rate and store a new config for it.

My old crt did, although The desktop was shifted 5mm to one side, but pressing the auto button shifted it back to center.

Rambling on a bit, but this worked for me on my old system, and it may work for you. PS> I only had to do that the one time.

Hope this helps, Glenn

For your usb wifi, get as much info about it as possible, like type, make, version and protocol. Try "lspci -v" in a Konsole or terminal it will list all of the devices detected on the pci bus, including agp and usb.

Then slip over to the networking section and check out the wifi forum. I mention the networking forum here at LQ because it may be faster, and that's where the wifi guru's hang out, just waiting to help.

Also, try the LQ search function, If you haven't already, some body may have already answered a similar thread.

Cheers!
