I would like to be able to change brightness, however. And have dimming. A minor problem, with the KMS Intel patch, when I log out of X (startx or xfce4), screen goes black. I don't know if this is acpi related. I typed reboot, and nothing happened. Using all.13.7-stable-9.patch with 9.0-STABLE. # cd /usr/ports/sysutils/acpi_call make install clean # rehash # kld_load acpi_call # acpi_call -p '\VBRC' -i 5 Exactly...I'd like to add it does require appropriate kernel sources, something I discovered as I'm currently testing off a 4gb USB...appropriately to current discussions, /usr/obj /usr/ports/distfiles /tmp /var/run are all tmpfs :) (we'll see how that goes too!). Some general followup/status of brightness: The hotkeys are working just fine out of the box, at least as far as they seem to adjust the brightness value seen by acpi_video, however as we know this doesn't actually seem to do much. There are a couple of branches in the ACPI code when brightness is called, one of which checks for integrated or discrete graphics (why I do not know as discrete is not an option). If \VIGD returns 1 (which I think means graphics are integrated) it talks to the \_SB.PCI0.LPC.EC.BRNS method, which doesn't seem to do anything for us. If \VIGD returns 0 (which I think would mean discrete graphics if available) it calls \VBRC The above method simply bypasses the VIGD switch and calls \VBRC directly. There are other ACPI methods which seem to be related, but I have yet to figure out what they mean...VBTC is one, and some _Q(X)(X) methods also seem to talk to the EC about the panel and brightness etc. It seems like we need to find how to make the EC be in charge of brightness instead of whatever VBRC is doing (it's an SMI call). I think brightness might just work fine...another note is the fact that acpi_video sees lcd0 as inactive...not sure why. Regarding acpi_ibm, it appears that it is also talking to the EC, which is why brightness cannot work there. Although for some reason, probably an alignment or address change, the fan speed appears corrupt after setting brightness via acpi_ibm, the fan controls still work fine in both manual and automatic as far as I can tell. It seems like if we can determine why the EC does not care for brightness settings, or isn't in charge of brightness, that we would be a small patch away from fixing acpi_ibm for this model. HOWEVER, it appears resume is now toast on CURRENT, since at least a few months, with or without Konstantin's patches. I'm not sure what's hanging, although setting suspend_beep=1 creates a horrible sound during the failing resume, which may indicate it's something fairly early in the resume, or even concurrent with beeping. Even bounce does not work, and debugging is complicated by the lack of display. If anyone has anyone ideas for fixing resume on CURRENT, we'd be awful close to having a pretty damn nice laptop for FreeBSD.

Yes, value changes with no effect when hotkeys are pressed...I am not sure why there is no effect. I could care less about suspend/resume as I don't really use it. Brightness and the fan (thanks for reminding me about the corruption) are what is killing my use. I have a SSD so even though boot isn't 5sec on FreeBSD, I can still live with waiting 10 extra seconds. Having brightness eat up my battery time and fan spinning like crazy is a problem, though. The fan is horribly noisy on this model. However, it will quiet down a bit on its own when temperature goes down...enabling C states and running powerd -a adaptive -b adaptive should help a lot...I don't recommend manual fan control as at least my i7 already runs way too hot in linux and win7 (for the 10 minutes I had it :) ). Run Lenovo bios updates as well, many complaints about post tsunami fans from Lenovo China instead of Lenovo Japan... What do you mean by the fan controls still work in manual and automatic? Does that mean every time brightness is changed, fan speed needs to be set to auto again for it to work properly? Only the fan speed value shows as 0x or something, however it can still be set 1-7 or back to automatic as usual Also, I assume the dimming from inactivity will not work until EC is responsible for brightness change? I'm not sure...that might be accomplished with dpms.ko, haven't tried ... and then I have the issue with Konstantin's latest patch for STABLE where after I exit X, I have no monitor or keyboard control. I guess I can bypass this with a login manager. http://wiki.freebsd.org/Intel_GPU On Konstantin's page he mentions this...it's a known issue Matt ___ freebsd-acpi@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-acpi To unsubscribe, send any mail to freebsd-acpi-unsubscr...@freebsd.org
Re: x220 notes
Hey Matt, thanks for clearing things up. It looks like this is an ongoing process ever since you first started the thread. The fan is horribly noisy on this model. However, it will quiet down a bit on its own when temperature goes down...enabling C states and running powerd -a adaptive -b adaptive should help a lot...I don't recommend manual fan control as at least my i7 already runs way too hot in linux and win7 (for the 10 minutes I had it :) ). Run Lenovo bios updates as well, many complaints about post tsunami fans from Lenovo China instead of Lenovo Japan... Actually for me, the HDD that came was much louder than the fan. I swapped it out in favour of a SSD until I am ready for mSATA + HDD. Also, I have the original Windows 7 that way. http://wiki.freebsd.org/Intel_GPU On Konstantin's page he mentions this...it's a known issue I feel dumb, because I did read that page many times in the past but didn't realize it's the same issue :D Only the fan speed value shows as 0x or something, however it can still be set 1-7 or back to automatic as usual Sorry for asking, but I just can't find this. What is the command for changing the fan speed, especially to auto?
