screen resolution not changeable

[michael]

Hi Michael,

thanks for your reply.

1. I can enabled Advanced Desktop Effect

2.when starting the display-applet, I see following at the terminal:
	awk: cannot open /var/log/Xorg.1.log (No such file or directory)
	warning: failed to get module paths from '/var/log/Xorg.1.log' -
falling back to default
	Xlib:  extension "XFree86-VidModeExtension" missing on display
		":1.0".
  but setting and testing another resolution failes. It seems that only 
  the current resolution is working.

I don't understand what went wrong when updating, because with 7.10 all
worked fine, I could adjust every resolution and had now performance
issues.
In worst case I have to wait for Ubuntu 8.10 ...

Michael
