But I noticed that if I click "Setup Helper Application" in KLaptop (so klaptop_acpi_helper becomes suid), my laptop uses all the power with no scaling (might be a profile problem?). I'm using KDE 3.4 but it was the same in 3.3. To let powernowd work again I had to manually chmod -s /usr/bin/klaptop_acpi_helper. I suggest to never enable it, because it has only 2 profiles: userspace (min freq), performance (max freq). So frequencies in the middle will never be used. Athlon64 (and Turion I think) has at least 4 operation modes. -- Alessandro Dal Grande Student In The University Of Padua - Computer Science Linux Registered User #359258 System: GNU/Linux Debian Sid Pure64 on K8@3200 Chat: Psi ICQ) 150487234 Jabber) alex84@jabber.linux.it Put the fan back into computing
