Failed to start the X server

the below are some posts from Zillah which were deleted after the database crash (or rather kernel panic plus crash)

 

i just happened to have the thread open on another computer so could copy the data back.

 

Running FC7. I installed several packages last night. Today, when I booted up the computer, I got this message:

 

Failed to start the X server (your graphical user interface). It is likely that it is not set up correctly. Would you like to view the X server output to diagnose the problem.

 

I tried Ctrl-Alt-F1 where I get the X server failure and go to a command line.

 

1- cat /var/log/Xorg.0.log | grep EE

CODE

(WW) warning , (EE) Error, (NI) Not Implemented, (??) unknown, (EE) unable to locate /open config file

 

(II) Loading Extension MIT-SCRENN-SAVER

(EE) Failed to load module vga (module does not exist, 0)

(EE) open /dev/fb0: No Such file or directory

(EE)<default pointer>: Cannot find which device to use.

(EE)xf860OpenSerial : No Device specified

(EE)<default pointer>: cannot open input device

(EE) PreInit failed for Input device <default pointer>

 

 

 

2- Then I run : Xorg -configure

CODE

Xorg is not able to detect your mouse. Edit the file and correct the Devices.

Your xorg.conf file is /root/xorg.conf.new.

To test the server, run 'X -config /root/xorg.conf.new

 

 

 

3- Then I run Xorg -config /root/xorg.conf.new

only last part of the long output

CODE

Fatal sever error:

failed to initialize core devices

Sounds like it was unable to load your mouse. Check the mouse device section in the configuration file. The check that the device exists in /dev/mouse or /dev/input/mice something like that.

reply from glennzo:-

 

You could also compare the mouse section in your old xorg.conf to that same section in the new xorg.conf. Might just need a slight change to one line.

repoly from zillah

 

CODE

ls -l /dev/mouse

ls : cannot access /dev/mouse:No such file or directory

 

ls -l /dev/mouse0

crw-rw---- 1 root root 13, 32 2007-12-12 16:07 /dev/mouse0

 

 

ls -l /dev/mouse1

crw-rw---- 1 root root 13, 32 2007-12-12 16:07 /dev/mouse1

 

 

ls -l /dev/mouse2

crw-rw---- 1 root root 13, 32 2007-12-12 16:07 /dev/mouse2

xorg.conf is already has been overwritten when I copied xorg.conf.new to /etc/X11

have you tried doing yet another yum update to see if the original xorg problem could be resolved ?

 

Yes, but no success unfortunately

 

Can I reinstall Xorg packeage by using yum ,,,yes there are other ways, but I am looking to use yum.

 

 

you might try

 

yum remove xorg-x11*

 

then

 

yum install xorg-x11*

 

I don't know if that will work....

 

cheers
