Just installed redhat linux. First boot. Everything is loading, many text scrools fast on screen. Some green OK's. Then everything disappears. Some logon appears, but the screen is flashing, it is hard to write something.

Then appears a grey window with this text:
"I cannot start the X server (your graphical interface). It is likely that it is not setup correctly. Would you like to view the X server output to diagnose the problem"
Two buttons: Yes and No

I pressed Yes. Then showed up something like this:
"(==) Log file: '/var/log/XFree86.0.log'
(==) Using config file: '/etc/X11/XF86Config'
(EE) No devices detected

Fatal server error:
no screens found"
and many other not so useful staff.

Button Exit. I pressed it, then showed one more message:
"Would you like me to try to run the X configuration program?"

Buttons Yes and No. I pressed Yes. I typed root password.
Something was working, on screen was something like this:
"* ddcprobe returned bogus values:
ID: None
Name: None
HorizSync: None
VertySync: None

Couldn't start X server, trying with a fresh configuration
* ddcprobe returned bogus values:
ID: None
Name: None
HorizSync: None
VertySync: None

Trying with card: VESA driver (generic)"

Then showed up a screen with nicer resolution, and there I could select a videocard type and monitor. By default there was Unknown monitor and VESA driver (generic). But I selected Ati Radeon 7000 videocard and Philips 105S, what I actually have. Pressed OK.

Showed a new message:
"Display settings changed
Configuration was written to /etc/X11/XF86Config, original configuration saved as /etc/X11/XF86Config.backup"

I pressed Ok. A new message:
"I will try to restart the X server again"

Again Ok. The screen is flashing again. And after a while showed a new message:
"I will disable this X server for now.
Restart GDM when it is configured correctly."

Pressed Ok.
And then only I could is to login as root. But only thing I can work with is command line.
What I should do to get that X server work?

I'm new to Linux however last time I tried to install it I had the same problem. I had to boot into text mode and edit the file: /etc/X11/XF86Config manually and change the line "driver" in Video Card section to "vesa". Try to run "startx" after that. I was trying to use an ATI Radeon 9600XT.

Wow!!!!! That really worked!
Love you man!

No problem. I'm glad it worked. However now I'm running Debian 3.1 (Sarge). I originally had the video driver set to "vesa" (with no troubles) and I took a chance and changed it to "ati". It works, granted nothing has changed in the looks or feel of it. Just thought I'd share that with you.
