Problem with x windows


I installed fedora 6 and had to use the text style install process due to the constant freezing of the gui install, I thought after I had it installed it would work, I was wrong. I run and boots then asks for a user name and password, I log in as root and type 'startx' it seems to work until it loads the desk top, the picture (the f and dna spiral thing) is jacked, it looks like when a tv gets bad reception. I know my screen is fine due to having windows installed on the computer also. I'm pretty sure I meet the system requirements considering I have 2 gigs of ram, and sli'd 7800's. The only response I have is my mouse (which I have to unplug and plug in to get it to respond), I can move it but can not click any thing. I am trying to get in to Linux because windows in ticking me off, so I don't know a whole lot about Linux or its commands in cil. I looked around the forum but could not find any one with the same problem, any help would be greatly appreciated.

Simple thing to try first: Ctrl_Alt_Grey+ or Ctrl_Alt_Grey- (the 'grey' keys with '+' and '-'). These keystrokes can normally be used to cycle through all of the resolutions listed in your /etc/X11/xorg.conf file (while X is running, of course). You may strike upon one that works. If still no go, post your xorg.conf file here (in [CODE ] tags, please), and we can take a look-see.

Nope, I cant do anything

All it will let me do at the desktop is move my mouse, I did try the changing the resolution, no success . The resolution looks right, I have a 19 in wide screen using dvi(could that have anything to do with it?). Whats weird is that the "task bars" look normal, just the desktop picture is messed up. And im sorry I don't know how to give you the xorg.conf. And I know its not a corrupted iso, cause I downloaded the 64 bit and regular one and both do the same thing. Thanks for any help

You need to supply a bit more info for people to help you. I assume you are posting to LQ by using some other OS, or by using a text-mode browser like lynx. If the former, copy your /etc/xorg.conf file to some media that is accessible from that other OS, and then copy/paste it into the LQ text entry window. How did you change the resolution? Are you able to run 'xdpyinfo'? If yes, then grab the output from that, and post it here. What vide hardware & drivers are you using? Are the drivers up-to-date? Is the monitor being correctly detected? Are you able to make things better at all with the xvidtune tool?

I cant or don't know how to get any of that, like I said, I'm really new. (/etc/xorg.conf) This is the only one I don't know how to do. I have yet figured out how to get on the internet with Linux in cil, so I'm using my lap top. I have two sli'd 7800 gt's, and I don't think I have any video drivers installed. when I type xdpyinfo it says "unable to open display "". " and xvidtune says "error: can't open display:".

You know whats really sad, I set up networks for a living (using windows). I know I'm a loser

First of all, what does "have two sli'd 7800 gt's" mean? I presume this is some sort of win-speak that describes your video hardware. It is likely that there is some configuration issue at the root of this. Do you have two video cards installed?
What sort of terminal were you in when you tried to run xdpyinfo? If the system is not in graphical mode (ie X running), then the command will do nothing, as you have witnessed.

Are you able to invoke a text-mode interface by typing 'Ctrl_Alt_F1' (or Ctrl_Alt_F2,F3,....)? If yes then report back, and we can procede with a diagnostic process. I don't want to start jumping ahead until I've established what we've got to work with.

Do you have any grasp of basic commandline use, directory navigation, and so on? We're going to need to look under the hood a little bit here. Might get your hands dirty...

I don't know about win speak but I do have two graphics cards installed, and sli'd means they run as one card, 7800 is their chip sets and gt is the model. I don't know about what terminal I'm in, I just log in as root and typed it. And every thing I do is in text mode there is no gui what so ever. I know very little, sorry, thanks for the help.

It would have been a good idea to mention that you have a bit of a special setup there.

Please clarify. You said that there is a 'task bar', but now you say there is 'no GUI whatsoever'.

Have you explored the video card manufacturer's web site or other resources for information regarding that configuration? I've never heard of such an arrangement, so I probably won't be too helpful. Still, if you could post the configuration file, something might jump out.
To do that, you will need to change to the /etc/X11 directory
Code:
cd /etc/X11
Then you can view the file:
Code:
cat xorg.conf
You can copy it to a floppy, if that would help you post it from a Windows browser.
Code:
mount /dev/fd0
mount                  (shows you where the floppy is mounted)
cp xorg.conf /mnt/floppy
umount /dev/fd0

You should post the contents of your xorg.conf file. Are you trying to use the second video card as a slave to increase the processing power of the first, or are you going use duel monitors? Or will you have a duel seat system ( 2 keyboards, 2 monitors operating independently for 2 users logged in at the same time ).

The Fedora Core forum on this site may have a sticky for obtaining and installing the propriety "nvidia" driver. I'm guessing that the "nv" driver may not support 2 sli cards and that may be what is causing the problem.

Another possibility is that the xorg.conf settings for the monitor is off. If the horizontal and vertical refresh rates are ok in your xorg.conf file, then using the gtf command may help fine tune a mode line. This can be especially useful if you couldn't find your exact monitor model in the FC video configuration.
gtf 1280 800 60 -x
will generate a modeline for 1280x800 at 60 Hz refresh. This is what I used to configure xorg.conf on my laptop before XGA was supported in sax2. ( I use SuSE Linux. ).

What I was saying about the task bar, I was talking about when I try to run in gui (startx) they the desktop pick is jacked and the taskbars and fine, but to do anything I have to be in cil mode. Im trying to run the cards as one card. I used both cards when I have windows in the system with the nvidia drivers and it ran great, I guess fedora does not have that driver. When I try to install it in gui mode, it asks if I want to see the specs on the os or next, and I can click on the buttons and they work, but random parts of the screen are messed up, when I hit next more of the screen is messed up and if I dont hit it fast enough it locks up. This makes me think the os recognizes the cards but I dont know what it means. I would try installing it on another computer, but if it messes up again I will not have a computer to find help on.

Well, my suggestion is to use those video cards for windows. I doubt if there are any games for linux that would really make use of an esoteric scheme like that anyway. Is the GUI mode even usable at all? It seems like a reasonable idea to try adjusting the resolution with Ctrl_Alt+/-, as I suggested earlier, IN GUI MODE. Even if you can't do any window manipulation, you still might be able switch to a usable, even if suboptimal, mode. From there it would probably be a lot easier to work toward a solution. Still looking for your xorg.conf file. That is definitely part of any remedy.
