Hello,

I install Fedora 10 on my computer first time,today. Running the KDE 4.1.2 be my X-window environment manager. While I use the automatic update, I set the some item (I didn't remember what item.)... then the screen turn to the full black.

My GPU is NVIDA GeForce 7300GT. I didn't think the video card will crash the X-window, because when I finished the installation I log in/out several time and never crash it.

After then, I enter the terminator mode (tty2~6) to start the X-window. But I got the warning below and didn't start the X-window:

Fatal server is already active for display 0, If this server is no longer running, remove /tmp/.X0-lock and start again.
Invalid MIT-MAGIC-COOKIE-1 Keygiving up.
Xinit : Resource temporarily unavailable (errno 11) : unable to connect to X server.
Xinit : No such process (errno 3) : Server error.

Frist way, I try to remove these files -- /tmp/.X0-lock; /tmp/kxocket-USER; /tmp/kde-USER; ~/.kde/tmp-hostname.
Then I reboot my computer, I got the same isuue and warning.

Second way, I use rpm packages -- arts, kdelibs and kdebase to reinstall on the system but it didn't work.

I want to recover my X-window as normal, didn't by reinstalling my O.S.
Please, give me some other way to fix this issue.
Thanks!!

You likely tried to activate KWin Desktop Effects. they can be disabled by editing the file $KDEHOME/share/config/kwinrc. Go to the section "[Compositing]" and find "Enabled" set it to "false"

You should then be able to login at KDM/GDM.

Hi,

I try to find the "kwinrc" file. It's not in this directory -- $KDEHOME/share/config/. I found it in this path -- /usr/share/kde-settings/kde-profile/default/share/config/kwinrc. But I can't find the section "[Compositing]" in this file.
My "kwinrc" file content was :

[Style]
PluginLib=kwin3_oxygen
ShowToolTips=true

[Windows]
AutoRaise=off
AutoRaiseInterval=0
BorderSnapZone=10
ClickRaise=on
FocusPolicy=ClickToFocus
MoveMode=Opaque
ResizeMode=Opaque
WindowSnapZone=10
WindowsPlacement=Smart

And I can login at KDM/GDM, only when I login KDM, the screen it will turn to black.
Thank you for your helps.

Try looking in ~/.kde4/share/config or ~/.kde/share/config

Thank you, sir.

I found the file and changed the setting into "false". Now, my KDE is normally. Thanks!!
