Ok, changing the display manager to SLiM makes the gmail test failing. I'm gonna use the system for a while, and then update. This is, really, odd. Thanks to everybody, your prompt answers make me feel nice:) Does somebody know something about the trace I'm getting at the end of dmesg and the mtrr story? thanks again! Ciao!
