But that's indeed a possibility I will investigate, along with USB-thumifying the iso file and dd'ing back the disk image it was shipped with. Though that's more complex and harder to schedule than downloading CURRENT sources, building them overnight and installing them on a USB flash. Though I will probably try with CURRENT instead of STABLE before trying BIOS update, since it's much easier to perform and I only need time to get at it. I also think that this is the easier way free of any risks. Well you could check BIOS/EC upgrade notes to try seeing if any of the issues fixed may be relevant, but there have been many issues and PRs fixed by nothing but a firmware upgrade, so I wouldn't skip that. The changelog from lenovo website does not contain anything related to ACPI or power management. But then again, said changelog is so light that I don't trust it to be complete, I rather expect lenovo to mention only significantly visible issues. So I will try the BIOS/EC update when I get the opportunity to do so. I just expect having an opportunity to boot CURRENT sooner.

Nonetheless, it's worth discharging and recharging both NiMH and Li-ion
batteries periodically. If you do it once a week that's only 52 cycles
per year; a small fraction of its design cycles, and unless you store it
partially charged in a fridge, less usage than its 'shelf life' anyway.
Apart from not harming the battery - which is designed for daily cycling
over 2 or 3 years - running it down past exhaustion now and again will
recalibrate the battery's onboard coulomb counter to reflect capacity.
At least when they were called IBMs, that was IBM's advice for Li-ion.

No secrets in FreeBSD, just stuff you have to hunt for and figure out :)
/usr/src/usr.sbin/acpi/acpiconf/acpiconf.c suggests hunting thus:
smithi on t23% find /sys/ -exec grep -H ACPI_BATT_ {} \;
[.. see usage in acpi_battery.c, acpi_{cm,sm}bat.c and acpi_machdep.c ..]

So 7 is no battery, 1 and 2 are discharging and charging, 5 and 6 are
critical discharging and critical charging (you'll see these shown by
acpiconf -i0 when the battery is very low) and 0 is fully charged.

In either case if you messed up too much I recommend a clean install. Follow Toto's instructions. That turned out to be the solution. I don't know exactly what was wrong, but it was somewhere in X: I deleted /usr/local /var/db/ports and /var/db/pkg and restarted from scratch, and since then video acceleration. I still have a few ACPI-related (I think) issues. For each of them, would you please tell me which ones are supposed to work (and I'm doing something wrong) and which ones are known not to work (and I'll try to figure out a solution)? * power button doesn't work: I'm used (on desktops too) to have ACPI somehow make it so that pressing the power button triggers a clean system shutdown, but it's not the case on my X220. Pressing the power button for several seconds does trigger a hard power off, but that's not what I'm interested in. * Fn key is registered as a sleep button: it is interpreted as XF86Sleep (keycode 150), but even when unbound in X it still triggers a suspend when pressed for a few seconds. Unintended suspends (e.g. when missing Ctrl key) are already uncomfortable by themselves, but they are made even worse by the nonfunctional resume. However, when I change sysctl hw.acpi.sleep_button_state to S5 (as a workaround for nonfunctional power button), Fn alone has no longer any effect other than sending XF86Sleep to X, and Fn+F4 correctly shuts down the system. * Disk led is never on, even when there is heavy disk activity. That's a very minor annoyance, but it would still be nice to see it solved. * Fn+Fsomething keys don't work, except for Fn+F4: I would consider them as functional if they sent some events to X (like Fn+arrows correctly send XF86AudioPlay, XF86AudioPrev, XF86AudioNext and XF86AudioStop) or if they were acted upon directly (like Fn+PgUp correctly switches the ThinkLight). * There is no way of selecting a pointing device. That's why I looked at Fn+F8 in the first place, since it's supposed to cycle between track-point only, touchpad only and both. Usually I'm fine with what I select from the BIOS, but there has been several times when I wished I could switch without rebooting. Ideally that would be hooked directly on Fn+F8 and/or through a sysctl, though having it through acpi_call would already be helpful for me. * The sysctl dev.acpi_ibm.0.wlan is read-only and always 1, no matter what the position of the physical radio switch is. * Something seems wrong with beeps (system bell): the first beep after booting sounds normal, but the following ones seem much faster (higher pitch and shorter), as if the sampling rate was suddenly much higher.

Both of these seem to be far beyond anything that I can reach in a reasonable amount of time :-( Still, my offer stands, and if anybody can think of anything useful I can do or learn, please don't hesitate to tell me so. Good news is that Konstantin's latest patch works with FreeBSD 9-STABLE so no longer need to run HEAD. I would love to see resume work, though. I'm not sure whether this is the right place to ask for such help, but I haven't been able to get it working as much as I would like. More specifically, I checked out 9-STABLE, and merged all 14 commits listed at the end of http://wiki.freebsd.org/Intel_GPU I then added WITH_NEW_XORG=YES and WITH_KMS=YES to /etc/make.conf and compiled x11/xorg metaport with default options, except for KMS=on for graphics/libdrm. It seems that adding i915kms in /boot/loader.conf freezes the system, but that's only a minor inconvenience. Now I kldload it just before starting slim. The screen resolution is correctly detected, everything in Xorg.0.log and `dmesg` looks fine, DRI2 is enabled, xdriinfo reports i915 dri activated for the screen. Well, all in all, as far as I can tell everything is fine, except I don't see any acceleration : it takes up to a whole second for my rxvt-unicode to refresh its 80x56 window (whether scrolling or switching tmux window, and no image background is set), opaque window moving is very jumpy (but I can live without it), and armagetron runs at 7-12 fps (to test whether 3D acceleration fared better than 2D acceleration). Do you see the same behavior? Would you have any idea on how to diagnose whatever could be wrong? Have you applied the kernel patches? Installing the new Xorg stuff after building them with the two lines added to make.conf. only builds the tools to send the appropriate requests to the kernel, but, without the patches, the kernel does not know how to deal with them. The required kernel changes have been committed to HEAD,but not to 9-Stable, so y0ou still need to manually apply these. -- R.

Re: How can I help with thinkpad x220 issues?
I don't suppose your Thinkpad maybe one of those that resumes properly, from X or from a VTY, with sysctl hw.syscons.sc_no_suspend_vtswitch=1 ? cheers, Ian No. I got my X220 AFTER the suspend/resume was broken. There was a point, I hear, during which it worked properly. I guess we are getting there. FreeBSD 10 has some hopes for me, including Intel GEM/KMS patch in code and some other goodies. -- Lyubomir Grigorov (bgalakazam) ___ 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

From a recent thread here I gather it almost works with FreeBSD, and the remaining problems are screen brightness and screen left unpowered at resume. Is that right? So my question is, how can I help make progress in any of these area? (though I admit I'm more interested in having the brightness problem solved than the resume one) I don't know anything about ACPI or about FreeBSD or Linux internals, but I'm quite proficient in C and somewhat used to navigate in unknown huge code bases. So I guess the first steps to help would be to first learn stuff. However I don't have much time available. I guess FreeBSD 11 would reach end-of-life before I could reach a level of understanding I find satisfying (though I admit I have high standards there), so I would have to prioritize. So my question is rather *what* should I learn to provide help as soon as possible? For example, if the brightness issue is just a matter of extracting the right numbers from linux kernel code and plug them into FreeBSD, I probably won't need to learn anything more about ACPI than what I would gather looking at the code. I guess if it was that simple someone would have already done it, but that illustrate well my point about prioritizing learning. Or is the barrier of entry too high for me to be of any use? If it has not been committed, the minor fix to make acpi_ibm work on modern ThinkPads needs to be committed. Once done, the issues mentioned need to be addressed.This includes getting brightness to be setable from both the keypad hot-keys and from applications. ATM, I can set the brightness, but making the hot-keys work will require the ability to extract the current level so that it may be adjusted plus/minus one. The other issue is volume control keys don't work. I suspect it will be similar to brightness, but I don't know just how to figure it out. I should also mention that I don't have an X220. I have a T520, but the issues seem to be identical, so fixing one will probably fix a lot of recent ThinkPads. -- R.
