Powertweak-Linux is a tool to tune your system to its optimal performance settings. It started life as the replacement for the now obsolete kernel option 'tune PCI bridges', and has been extended to provide more features and support more chipsets. It can also tune network/filesystem performance using /proc/sys entries, disk elevator settings, and x86 CPU registers (needs 2.2.18 or 2.4.0test kernel), CDROM speeds, hdparm type features, and Sony VAIO backlight. It has both a GTK GUI and a text-based lister.

Release Notes: This release adds a DMI BIOS hardware configuration info plugin, some 2.5 kernel proc settings, and a new text-based settings lister (lspowertweak).
Release Notes: The Disk Submenu works again, the 'BrandName' field was removed, and the CPUName field improved. The CPU Name can now be any length, and the identity structure is now cleaned prior to use. The hdparm backend got an overdue cleanup, and no longer carries excess ioctl info. Allocation routines have been made simpler. Sonypi backend now unloads if no Sonypi hardware is present.
Release Notes: The daemon handles HUP correctly, SMART code doesn't keep device fd open, and the install no longer overwrites existing config files. The CDROM backend respects min/max settings in /proc, and the CPU backend handles SMP boxes and steppings correctly. Tweaks that have changed value since the daemon has loaded reflect their current state in the UIs. New options were added, like a powerdown joystick port option for ymf744b sound card and a daemon --no-info option to skip `info' tweaks. Pentium III/Athlon XML and an informational MTRR backend were added, and many other fixes & cleanups.
Release Notes: Fixed problems with textmode UI not building if libxml1 & 2 were installed, and with some backends not setting values on daemon start-up. Socket is now created in /var/run for LSB compliance. Daemon now shuts down cleanly on SIGTERM. A small SIGHUP cleanup was added. All backends now honour the 'immediate' flag correctly. SMART backend no longer saves number of errors in config file. Loading of plugins when daemon not running moved from UI to libpowertweak. LibXML is now linked against libpowertweak instead of the UI. Fix was added to address PIIX4-0 xml DTD non-compliance issue. NFS server profile was added. Improvements were made to tool-tip pop-up docs.
Release Notes: Several segfaults/memory leaks have been fixed. The ownership model of the "stringvalue" memory has been changed. User interfaces now only run as root. Daemon socket creation/usage has been cleaned up. SMP boxes no longer show CPU0 values for all CPUs. sysctlconfig has been removed, as gpowertweak does everything it did. Now builds with libxml2 if present. There are Autoconf 2.50+ fixes, and lots of configure.in cleanups. It will now recognise AMD K6 MTRRs. New backends, preliminary hdparm support, IDE Health monitoring (S.M.A.R.T), and AMD K6-3+ PowerNOW support have been added. The elevator backend now works (This was in 0.99.0, but was disabled due to a bug). CDROM speed tuning and Sony-pi support (Vaio LCD backlight brightness) have been added. CPU XML now supports Pentium MMX additional power saving mode, and Pentium IV support (Fast strings, power saving) has been added. This release adds Extra PCI XML support for VIA 82C686, 82C698-0, 82C691 and Intel 82441-FX & 82434, PCI XML fixes for VIA 82C598, 82371AB PIIX4-1, and Intel 82437-VX, and preliminary TUX webserver support.
