Throttling the Mobility Radeon

December 23rd, 2005

While I like my Thinkpad, I dislike the fan noise that it makes. On Slackware you literally have to turn on some music to drown out the constant whirr of the fan. The GPU itself is a Mobility Radeon 7500, but unfortunately crappy ATi haven’t bothered to release a Linux driver that caters for it so I could have native hardware acceleration and Powerplay throttling. Cheers ATi, I’ll look into nVidia next time.

Anyway, all is not lost. There is an option in the kernel that gives you their equivalent of Powerplay–Dynamic Clocks. By enabling this and editing your xorg.conf file your battery will last for a little longer, and the fan won’t make so much noise. I’ll just point you to ThinkWiki instead of listing all the instructions here, because I’m not on Slackware at the moment.

Having to reinstall everything because my kernel somehow got corrupted. Hopefully my hard drive won’t need replacing…

    If only your file system was reiserfs rather than ext3. Then you could have tried from a livecd/dvd:

    # reiserfsck –rebuild-tree -S -l /dev/hda*

    Where “*” is of course the number of the afflicated partition/drive. Until there is something much like it for ext3, I don’t intend to use it for my /home partition. :)

    Cheers for the tip Pascal but my home data is actually fine :S

    It’s the kernel that got corrupted somehow.

    I suppose my Thinkpad is rather nice, but before that I only had a 450mhz Pentium 3 to play around with. Aranil, it’s not how big it is it’s how you use it ;)
