During the installation of fedora core 6 in graphic mode. The linux can detect my video card(Geforce 7900GS).
But after complete installation when I boot the linux, the screen goes blank in the same time of starting graphic mode.
Can anyone tell me what going on? And what should I do to fix this problem.
Thank you so much.

Assuming you've nothing on there of value, reinstall.... however, its probably worth _not_ using the NVidia drivers. There's quite a few problems with them at the moment, so just use a generic renderer (VESA, SVGA....) to get it running.

If there is stuff on there you need to keep, you could try blindly logging in as root, then typing "telinit 3". That should reboot into non-graphical (ie command line) mode. From there you could try to uninstall the nvidia drivers (yum remove kmod-nvidia of the top of my head, but check that first) After that, typing "telinit 5" wil reboot you back into graphics mode.

HTH, Matt

Sorry, I'm very new to linux.
Could you tell me which step of installation that I can select the generic renderer.
I have nothing on there of value.
Thank you.

So am I

Ah well.... basically, one of two choices, and the first one is a hell of a lot easier...

1) During (re)installation (just put fedora disk one in and boot from it, select install) when you get to the part asking what programs you want to install, make sure that the 'choose choices now' (or something like that) radio button is checked, then click next. It'l show you a list of everything you could install, so you need to find things with nvidia in them. The ones you need to get rid of start with kmod-nvidia and xorg-x11-nvidia. Find those, uncheck them, and continue with installation. As an aside note, you'll probably want to install the standard development package, as it'll be needed to build some drivers. I needed it to install my network card.... so you can imagine how difficuhttp://images.linuxquestions.org/questions/images/smilies/rolleyes.giflt it was to find answers on the internet

2) After getting into command line mode, you can use yum to uninstall kmod-nvidia and xorg-x11-nvidia. Again, check on the names and how to uninstall stuff with yum. I've never had to do it...

As I've said, the first option is much easier, and if its a fresh instal, theres likely nothing of value on there.

It should be this page right?
http://fedora.redhat.com/docs/instal...selection.html

I can't find it anywhere.

thats the page. You can't find the page or can't find the nvidia drivers?

If you've found the page, they're probably hidden in the Base (on the left), X Windows (or the right) category.

If you can't get that page, you need to go to http://fedora.redhat.com/docs/instal...selection.html
and make sure the 'Customize now' radio button is checked. (Its near the bottom)

I can't find the nvidia driver.
I've already tried to find it in X windows.
All I found was xorg-x11-apps,xorg-x11-resutlls,...,xorg-x11-xfs-utlls,xorg-x11-xsm.
But I couldn't find the xorg-x11-nvidia nor kmod-nvidia.
I've already tried to find it in further location but I coundn't find it.
Should I have to do something to unselect the package? May be the package is not in the optional packages.
Thank for your help.

I found the package name xorg-x11-drv-nv on the linux dvd-disc. But I don't know how to not install it.

the xorg-x11-drv-nv is the fedora driver for nvidia cards... which should wourk reasonably well... ie, it'l run.

Something wierd going on. Have you tried just reinstalling?

Sorry, I forgot to tell you that my graphic card use DVI port.
I search on the internet and find solution about adding 'Option "UseDisplayDevice" "DFP"' to xorg.conf but it's not work.
I've already try with DFP-0 but it's not work too.
Oh I almost forget that blank screen should be no monitor signal and when i press ctrl-alt-f1 the text mode can work well without problem.
Thank for your help.

okey... so text mode works fine.....

is it possible to try an analogue output? or have you just got a digital output?

shouldn't make any difference but its worth a try...

Also, have you tried typing "startx" into the console view? It'll probably throw up an error message (at least I hope so) saying X is already running...

if it doesn't, you have yourslf a workaround for the time being...

I give up! I've already change my graphic card to the one with analog output and it's work well.
But thank a lot for your help.

I've got the same card and the same problem, I'll mess around with it and tell you if I find anything.

i have the same problem. graphical installation (FC6) is going well. then i reboot: after loading HAL demon and smartd the screen is suddenly turning black on ALL tty's so there is no console to work on. any idea? the system is a dell PE 18000 server,

okay. i used the dvd to boot per linux rescue and chrooted to my filesystem. in xorg.o.log is says:

[...]
(**) RADEON(0): Initializing Acceleration
(II) RADEON(0): Render acceleration enabled
(**) RADEON: EngineInit (32/32)
(**) RADEON(0): Idle timed out: 64 entries, stat=0x80010140
(EE) RADEON(0): Idle timed out, resetting engine...

and then the last 3 lines are repeaded several times. thats it.


--> i switched to vesa in xorg.conf and now it works, however this is maybe not the best solution.
