XIO: fatal IO error 104 (Connection reset by peer) on X Server ":0.0"

Hallo zusammen,

die KDE-Oberfläche meines Webservers startet nicht mehr.
Beim Ausführen des Befehls startx erhalte ich folgende Meldung:

Kann mir hier jemand weiterhelfen?

EDIT (autom. Beitragszusammenführung) :

Ich habe den Fehler lösen können!
Ich hatte zum Glück eine Sicherung der xorg.conf ( Pfad: /etc/X11/ )

Auszug aus der xorg.conf:

Die falschen Einstellungen:
Section "Device"
BoardName "515E)"
BusID "1:3:0"
Driver "radeon"
Identifier "Device[0]"
Option "alwaysshared"
Option "alwaysshared"
Option "rfbauth" "/root/.vnc/passwd"
ChipId 22889
Option "usevnc" "yes"
Screen 0
VendorName "ATI"
EndSection


Section "ServerLayout"
Identifier "Layout[all]"
InputDevice "Keyboard[2]" "CoreKeyboard"
InputDevice "Mouse[1]" "CorePointer"
InputDevice "Mouse[3]" "SendCoreEvents"
InputDevice "Keyboard[4]" "ExtraKeyboard"
InputDevice "Mouse[5]" "ExtraPointer"
Option "Clone" "off"
Option "VNC" "5 4"
Option "Xinerama" "off"
Screen "Screen[0]"
EndSection


Die gesicherten Einstellungen:
Section "Device"
BoardName "515E)"
BusID "1:3:0"
Driver "radeon"
Identifier "Device[0]"
Option "rfbauth" "/root/.vnc/passwd"
ChipID 0x5969
Option "usevnc" "yes"
VendorName "ATI"
EndSection

Section "ServerLayout"
Identifier "Layout[all]"
InputDevice "Keyboard[0]" "CoreKeyboard"
InputDevice "Mouse[1]" "CorePointer"
InputDevice "Keyboard[2]" "ExtraKeyboard"
InputDevice "Mouse[3]" "ExtraPointer"
Option "Clone" "off"
Option "VNC" "3 2"
Option "Xinerama" "off"
Screen "Screen[0]"
EndSection


Da muss sich der X-Server wohl mit der Zeile
InputDevice "Mouse[3]" "SendCoreEvents"
verhaspelt haben. Vielleicht kann das ein Linux-Spezialist mir das als Anfänger erklären?
