I have been testing Geubuntu 8.04 for a couple of weeks now on my Inspiron 1525n laptop that came preinstalled with Ubuntu 7.10. I works pretty well, cpu usage is low, memory usage is low also. Only problem I have found is that the multimedia buttons don't work ie volume, mute, play, etc. These worked fine on standard Ubuntu 7.10 and 8.04. Does anyone know if the is a package that has to be installed to get these to work again?
Also this distro did not work out well for my desktop Dell Inspiron 531 AMD64 system. Cpu usage stayed maxed out all the time and it seemed to run much slower than Compiz-fusion.
