I wanted to change font and get too big resolution!
 

In control center i wanted to change font and choose newspaper which size is i think 25. After that there is a too big resolution when i open any window (desktop icons and background are ok). It is slackware 12.2 and root user. Other user doesn't has this problem. Also i changed kde to xfce and have same problem. Can anyone help me!

Can anyone help me?

Not too sure what you are asking. 25 is much too big a font size to use for kde components. I use tahoma at 9

Yeah, that's right, it's too big font size for kde and i can't change this from kde. How can change this from console?

you could try to delete
/root/.kde or rename it and restart kde

If you have messed up your kde settings you might try deleting your .kde directory. You had best do this as another user su'ing to root.

Thanks people, it helped me. I renamed /root/.kde directory from console and after that run startx and passed trough kde wizard and now everything is fine. Did there were a possibility to change this setting without deleting .kde folder.

If you look in .kde and browse through the config files, you'll probably find the option.

Now I am back at my home machine it looks like .kde/share/config/kdeglobals has the settings.

I am not so expirienced user, couldn't find files i need to change. I will try again.
