No Screens FOUND!

[jash143]

i have fedora6 which i have installed on an older computer. i first tried using Knoppix which loaded into itself just fine, but had some of its own problems. So i heard that this flavor was alot more stable. But my newbie self has run into a problem. everytime i try and run xserver i get an error.
(==) Logfile: '.var/log/xoerg.0.log"
(==) Using config file: "etc/X11/xorg.conf"
(EE) NV(0): No Valid modes found
(EE) Screen(s) found, but none have usuable configuration

Fatal Server error:
no screens found
XIO: fatal IO error (Connection reset by peer) on X server ":0.0"
after 0 requests (0 known processed) with 0 events remaining.

Now i have been reading forums and have come across some good ideas. but as i try and use the command given i get the no file found problems. i just happend to buy another graphics card thinking mine was to old. the one i got was a nvidia. i have also tried to run ubuntu from the live cd and i get the same error. x server cannot be started. i am very new to linux and how to use it. so i am wondering what i need to do.

If the knoppix worked then you can look at the /etc/X11/xorg.conf file from it and then the one from the install. See the differences. Nvidia card will more than likely need to install the Linux Nvidia drivers from the Nvidia site. Lots of post here on doing that and from the readme of the site.

ok i hear what your saying, but i have no idea how to look at that /etc/... file. i have tried to use yum and my network card at startup gives me some tulip eth0 not recognized (failed). and if i get the drivers how to i install them? i read somewhere that it could be the screen resolution, does that sound right? and if your sure its the card not being supported how do i fix that?

[Brian1]

If you boot with a live Knoppix CD on the linux machine and the graphics works then all you need to do is goto /etc/X11 and open it with one of many editor programs on the Live CD. Then mount the partition that contains the /etc directory of your install in Read-Write mode and edit the /etc/X11/xorg.conf file on it. In the gui you open two seperate windows so you can compare them.

As far as the network nic then that depends on the nic itself. You can get that info from the command ' /sbin/lspci -v '. From that you can use the search tool here for the card and see what module it uses. If no luck check on google for it as well for the linux module of that model.

Well after alot of thought and frustration i figured out something. when i boot into knoppix using thier live cd, i see that it tries a few confg x server settings. well the one that works was called 'fbdev' and when it tries that it works. now as far as i can tell i dont see anythign on the forums about using those setts in fedora. so any ideas? or anyway of getting those sets in my etc/x11 file on my hard drive where fedora is installed?

[jash143]

i also thought i would tell whoever that i copied the xcofg file after knoppix was up and running, and i put it onto a thumb drive. is there anyway possible that i can replace the file on my fedora hd and have it work that way? just a thought thanks in advance :)

[jash143]

is there anyone out there to help?

[Brian1]

Without seeing the xorg.conf file from current install and the one from knoppix boot to see what modules it is using. I would back up the curent xorg.conf file first. Then replace the xorg.conf from the knoppix to your install. Only thing to do is just try it.

[jash143]

well how do i copy it? i have tried all the usuall commands for editing xorg, and i always get the command not found thing. i have the live disk and the xorg file on mu flash drive, is there any way to copy either of those and if so, how? :) :confused:

[Brian1]

What editing command are you trying to use and where are you doing it. From a booted live cd like Knoppix or from the cli boot of your distro.

Brian

[jash143]

well i try and edit it with the fedora root command line. i have tried all the edit commands i have seen in forums as i come across them. im not sure what ones specifically. i got it to work once and i had no idea how to edit the file, but i could see xorg.confg i typed help and it gave me options that i didnt understand, like hitting keys to do specific actions. some of the keys i did not recognize. when i boot using knoppix live cd, i can not see my hard drive only the two ram sticks. but when i plug in my flash drive i can r/w to it. so that is when i copied the xorg file to try and make the fedora confg file the same.

[Brian1]

For text editing I know vi exist. It is a whole different animal to begin with. Maybe nano exist. Pico is another good but oldly one but doubt that one is default installed. Others for the most part require X to be running like kedit, gedit, nedit, and a slew of others.

If all you have to work with is vi then do as follows.
vi /etc/X11/xorg.conf
The file opens. Hit ' i ' to go into insert mode change what is needed.
When done hit ' esc ' key.
Now to save and if in lower case charcters hold down the shift key and hit ' z ' twice. Like ' ZZ '

Before changes make a backup copy. ' cp /etc/X11/xorg.conf /etc/X11/xorg_backup.conf '

All the above must be done as root.

im having the same issue here.
have tried to install the legacy drivers, but then i dont have 3d acceleration stuff.

[Brian1]

If using the nvidia driver from the kernel itself then it is very basic in the most part. The one you list doing in post #14 will give you 3d acceraliting. The nvidia if installed from source must have kernel-devel rpm install matching the current running kernel. If rpm is installed again it must match the current running kernel. Nvidia driver module is built to run with a certain kernel. If you change the kernel then recompile is required or matching rpm version. One can not copy kernel nvida from say 2.6.19.3 to a 2.6.19.4.

hi there

i have installed all nvidia drivers with yum: kmod-nvidia, legacy and 96xx
but i still dont have 3d acceleration.

using cedega to test it ( i dont know how can i test if i have 3d acceleration without cedega )
i have only opengl direct rendering working, but not 3d acceleration

do you know what can i do to test if i have 3d acceleration ? or how to get it ??
thanks

[Dies]

glxinfo | grep "direct rendering"

direct rendering: Yes

glxinfo | grep "vendor"

server glx vendor string: NVIDIA Corporation
client glx vendor string: NVIDIA Corporation
OpenGL vendor string: NVIDIA Corporation

That should be your output for a working Nvidia setup.

To the OP, did you ever get your problem solved?

[ilbh]

running glxgears im getting very low fps
glxinfo says i have direct rendering
but the test fails in cedega...

what you mean about OP ?

thanks

i used the vi command and i got it to edit the file on the first try. now my only problem is what am i trying to edit? i see in forums that you have to change the graphics to 'nvdia' insted of 'nv', but then it says there is no driver called that. so i went to the nvidia site and got the linux driver, but how and where do i put the driver so i can use it in my xorg.conf file?

[ilbh]

have you read that ?
http://forums.fedoraforum.org/forum/showthread.php?t=99285&highlight=nvidia+screen

then you can read this:
https://www.redhat.com/archives/fedora-devel-list/2006-February/msg01178.html
its from
Mike A. Harris,
Systems Engineer, X11 Development team,
he says that you should install your nvidia drive and xorg-nvidia from the same repository.
i recommend you installing from livna, avoiding to install from nvidia website.

have you tried to install the others nvidia drivers? like legacy or 96xx ?
