No screen found...


Well, I got a monitor for my pc and I have installed rh9. The installation process went fine; it recognized the video car "ATI Radeon 9000" and the monitor settings. When the system boots up, I choose RH9 and screen starts blinking in the user login info and then it takes me to a blue screen where it said that X server couldn't be started... it tried to run X thru Radeon 9000 but it didn't work. I'm a on redhat and I really need help on this one. Thank you!!

did you try running the x configurator? sounds like there are some wrong setting(s) in your config...
boot up again, and type :
xf86config
at the prompt and run through the configuration and see if that helps...good things to know off hand are things like the monitor vertical and horizontal frequencies, and the video card informatoin....you can just double check with the correct info that you have and just make sure nothing is getting picked up improperly and you can easily fix it and specify the correct values if need be.

Well, I try that already and it's still giving me the same error. I don't know if its a problem with the video card. If it is, is there any file or drive that I have to install for this video card? I look at the error message and still says "no screen found' and it also show Radeon 9000 video card. HELP!

usually a 'no screen found' error means that you don't have your /etc/X11/XF86Config file properly configured.

Please post the relevant portion of this file here, you don't need to post the whole thing, just the bit that starts with:
Code:
 # **********************************************************************
# Screen sections
# **********************************************************************

# Any number of screen sections may be present.  Each describes
# the configuration of a single screen.  A single specific screen section
# may be specified from the X server command line with the "-screen"
# option.

open a terminal, type
'less /etc/X11/XF86Config'

scroll down to the relevant 'screens' section, highlight it, copy, then paste into the form here

ok this is a monitor issue, not a gfx card issue...your going to have to run your X configurator and setup your monitor properly..its not picking up the V and H frequencies properly you will have to manually type these in when you find what they are either by looking in your monitor manual or going to the manufactuers site...

well you got two options:
1-) in your /etc/X11/XF86Config file change the settings that you find in the monitor section
2-) re-run the x configurator and select the option from the menu to manually enter them..

Thank you Drozz. I just need a little bit more info on how to edit that info! I think I'm on the right track, I just don't know how to edit XF86config.

Thank you again!

well you have to open up the /etc/X11/XF86Config file with a text editor, and a couple of examples of a text editor would be:
vi
emacs
pico
to name a couple....so for example if you choose pico you will type:
pico /etc/X11/XF86Config
and you will scroll through that file until you find the part called:
Section "Monitor"
and type the H and V frequencies in replace to what is already there....
now like i said previously you can do that, or you can simply type:
xf86config
in the terminal and that will run the X Configurator, and you will go through a series of questions, and when you get to the section about the monitor, you will select the option to manually enter the H and V frequencies rather than letting the config probe for them automatically...
