Most still don't work. Only volume mute work, but that worked before the change. Trying to change the brightness didn't "corrupt" the fan. Neither from hotkeys, nor from acpi_call > You'll notice that fan speed becomes something ugly after trying to set brightness, but everything will work otherwise as far as I have tested. > I have found that the machine gets quite hot on its own especially with turbo core on the i7 and heavy usage, even with power tuning. > Adjusting fan speed could be dangerous, I would certainly keep a close eye on temperatures during something like buildworld to be sure. On the other side, my temp now drops below 50C to about 46C. The fan goes into its lowest spin. I didn't have this before. At 50C it kicks to next step, at 60C it kicks to the crazy speed (usually on compile or 720p video). P.S. All tests were done from X with Konstantin's patch on 9.0-STABLE with powerd and no other mods. X220 with i5 2520M, BIOS 1.28, IPS, 9cell batter, 16GB RAM, Intel 1000-N, SSD. P.S.S. Workaround for fan corruption can be changing the brightness while it boots, before OS starts, function keys work there. But I don't have the crazy fan. If by crazy fan you mean not the lowest spin, then I had that before LEN change as well. -- Lyubomir Grigorov (bgalakazam)
