acpid scripts for laptop Fn+F2/3/6/7/8 functions

[nick65go]

My modest try to solve annoying problems with my laptop Fn keys.I think my HP laptop has a bug in UEFI firmware. It always was the same problem with BIOS for any PC I bought, because they came with Windows 7/10 preinstalled. And Dell /HP did not care about linux
The Fn keys that I need most often are F2/F3 for brightness and F6/F7/F8 for sound volume control.When the laptop starts, the fan is very noisy, because the brightness is very high (near insupportable). Plus the battery will deplete very fast (high power consumption).
So, basic things, but they can keep a user away of TinyCore/Linux if they are few but critical.
After trying in aterm a lot of basic commands for alsamixer, amixer, flit, etc, reading about acpid,here below is my acpid config. hope is usefully for some one.
home/tc/.acpi/actions.sh

Code: [Select]

#!/bin/sh
case $1 in
  button/mute*)
    MST=`amixer controls | grep 'Master Playback Switch' | cut -d, -f1`
    if [[ -z `amixer cget $MST | grep "values=on"` ]]
     then
       amixer cset $MST on
     else
      amixer cset $MST off
    fi;;

  button/volumedown*)
    MST2=`amixer controls | grep "Master Playback Volume" | cut -d, -f1`
    VOL=`amixer cget $MST2 | grep ": values=" | cut -d= -f2`
    [[ $VOL -ge 4 ]] && amixer cset $MST2 `expr $VOL - 4` && exit
    MST1=`amixer controls | grep "Master Playback Switch" | cut -d, -f1`
    amixer cset $MST1 off;;

  button/volumeup*)
    MST2=`amixer controls | grep "Master Playback Volume" | cut -d, -f1`
    VOL=`amixer cget $MST2 | grep ": values=" | cut -d= -f2`
    [[ $VOL -le 83 ]]  && amixer cset $MST2 `expr $VOL + 4`
    MST1=`amixer controls | grep "Master Playback Switch" | cut -d, -f1`
    [[ -z `amixer cget $MST1 | grep "values=on"` ]] && amixer cset $MST1 on;;
 
  video/brightnessdown*)
    BG=`cat /sys/class/backlight/radeon_bl0/actual_brightness`
    [[ $BG -ge 9 ]] && echo -n `expr $BG - 8` > /sys/class/backlight/radeon_bl0/brightness;;
  video/brightnessup*)
    BG=`cat /sys/class/backlight/radeon_bl0/actual_brightness`
    [[ $BG -le 247 ]] && echo -n `expr $BG + 8` > /sys/class/backlight/radeon_bl0/brightness;;

  # *)
  #  popup $1;;
esacI tested by running as root:

Code: [Select]

root@box:/home/tc# /usr/local/sbin/acpid -dmy acpid event-config is just a small file /etc/acpi/event/all,

Code: [Select]

tc@box:/etc/acpi/events$ cat all
event=.*
action=/home/tc/.acpi/actions.sh "%e"

[nick65go]

and the fight against Goliath (laptop!) continue...When the lid is closed, the Diplay is OFF, but other parts are NOT in standby (I hear the fan, the small-left led is still continuum lighting, not flashing as in standby.So basically the LID switch is just for display, not for stand by. When laptop cover is lifted up, the display turn on.
Looking into /var/log/Xorg.0.log I see at least:

Code: [Select]

Power Button (/dev/input/event0)
Lid Switch (/dev/input/event1)
And now the improved/continued list of events for acpid

Code: [Select]

  button/power*)
    exitcheck.sh shutdown;;    #<-- thanks tiny core
  button/lid*)
    echo -n "mem" > /sys/power/state;;

  *)
    popup $1 &
    sleep 1
    kill `pidof popup` &;;
esac
tamimg the beast. TBC...

[nick65go]

now there are people who do not give a shit about Fn-F# keys. Right. We can use aterm very easy, if we per-define some aliases:

Code: [Select]

tc@box:~$ cat .ashrc
alias suspend='echo mem | sudo tee /sys/power/state'
alias low50='echo 50 | sudo tee /sys/class/backlight/radeon_bl0/brightness'

Ok you need a little flexibility for brightness?

Code: [Select]

tc@box:~/.local/bin$ cat brightness.sh
#!/bin/sh

BG=`cat /sys/class/backlight/radeon_bl0/brightness`
echo "Curent brightnness is" $BG
echo "
1.   Minim ~0% (Are you crazy?)
8.   Hurry Battery is Low!
16.  Economic
32.  GOOD BOY
64.  Medium
128. Very Bright
192. Extremely Bright
255. Max 100% (Are you crazy?)

Type Brightness Number: [1-255]"

read -s answer
echo  $answer | sudo tee /sys/class/backlight/radeon_bl0/brightness
echo "Done! bye"
read junk; exit
Now another bad habit of the laptop is that the battery runs silent until remain 1%. WTF? then I have maxim 20 seconds to plug the adapter, or bye-bye unsaved work.Time for a cron job? [never tried one] to test every 10-20 minutes the battery capacity? or when is near (lets say) 5% to popup a messge like: "My Lord, plug the F**king power cord, battery is x%"

[curaga]

About suspend by command, IIRC in some laptops the enter key press comes so late it causes a wakeup. On those I added a sleep in front,

Code: [Select]

alias suspend='sleep 1 && echo mem | sudo tee /sys/power/state'
Battery alarm like that is a hw/bios function, and you indeed need a software poll setup for other thresholds and notifications.

[nick65go]

Thanks curaga for support. I am still thinking about a simple script for crond job, stubborn in using FLTK only as much as possible.

Now the battle with sound and video continue. I hope I won.
ALSA has a bad habit to see HDMI first then Digital sound card. And radeon driver should adjust the clock to low speed to stay quiet for longer.
(I have an AMD A6-6310 APU with AMD Radeon R4 Graphics integrated).

Code: [Select]

tc@box:~$ ls -lR /etc/modprobe.d

tc@box:~$ cat /etc/modprobe.d/snd_hda_intel.conf

the misleading thing was that i need options snd_hda_intel (not snd-hda-intel) even if modprobe has letters with "minus", not "underscore"

tc@box:~$ modinfo snd_hda_intel
filename:       /lib/modules/5.4.3-tinycore64/kernel.tclocal/sound/pci/hda/snd-hda-intel.ko.gz
And finally, for sound testing, aplay is not working by default. because missing few dummy files in /usr/local/etc/alsa/cards (shame-less taken from alsaconfig.tcz)

Two more small victories. Like the song says "another one bits the dust".
It was about input devices. My UK keyboard does not let me type € (euros sign) for Alt-gr + 4.
And the touch-pad is clever in Win10 but stupid in linux. It seams the modern "all-inclusive" libinput (in preparation for Wayland?) is good replacement for evdev, but libinput has not all options as old/trusted synaptics.

Code: [Select]

#/etc/X11/xorg.conf.d/20-keyboard.conf
Section "InputClass"
    Identifier "My Keyboard"
    Driver "libinput"
    MatchIsKeyboard "yes"

    Option "XkbLayout" "gb" #not uk!
    Option "XkbVariant" "extd" #not intl
    Option "XkbOptions" "euro sign:4,terminate:ctrl_alt_bksp"
EndSection
An inspection on /var/log/Xog.0.log shows that only synaptic driver takes my options=.., ignored by libinput "master of inputs"

Code: [Select]

#/etc/X11/xorg.conf.d/70-synaptics.conf
Section "InputClass"
    Identifier "My Pad"
    Driver "synaptics"
    MatchIsTouchpad "on"
    MatchDevicePath "/dev/input/event*"

    Option "TapButton1" "1"
    Option "TapButton2" "2"
    Option "TapButton3" "3"

    Option "ClickFinger1" "1"
    Option "ClickFinger2" "2"
    Option "ClickFinger3" "3"

    Option "RTCornerButton" "2"
    Option "RBCornerButton" "3"
    Option "LTCornerButton" "1"
    Option "LBCornerButton" "1"

    Option "VertEdgeScroll" "1"
    Option "HorizEdgeScroll" "1"
    Option "VertTwoFingerScroll" "1"
    Option "HorizTwoFingerScroll" "1"
    Option "CornerCoasting" "1"
    Option "CircularScrolling" "1"
    Option "CoastingSpeed" "2"
    Option "CoastingFriction" "5"
    Option "SoftButtonAreas"  "60% 0 82% 0 40% 59% 82% 0"
EndSection

FYI: all these little things (keyboard, audio, sound) keep users on Win10 (bloat/spy).

What happens without xf86-input-evdev and xf86-input-synaptics loaded?

[Juanito]

in preparation for Wayland?

wayland has been available for some time now in CorePure64 - have you tried the weston compositor?

[nick65go]

Hi Juanito, as I said, by default I do no load xf86-input-evdev, neither xf86-input-synaptic. xf86-input-libinput just works.but it ignores my options from

Code: [Select]

#/etc/X11/xorg.conf.d/70-synaptics.conf
Section "InputClass"
    Identifier "My Pad"
    Driver "libinput"

So I need to load xf86-input-synaptic also.

Code: [Select]

#/etc/X11/xorg.conf.d/70-synaptics.conf
Section "InputClass"
    Identifier "My Pad"
    Driver "synaptics"
About wayland, i have no clue, just reading articles about why evdev is replaced, and libinput promoted (maybe for touch screens, etc)
FYI: I am still at base things, like Xorg + FLTK. partial GK1/2/3 as imposed by others like firefox.

[nick65go]

just to confirm, again, that libinput ignores my syntax for "options=" from 70-synaptics.conf
I delete /var/log/Xorg.0.log, I modified the (only one on my laptop) 70-synaptics.conf, to have

Code: [Select]

#/etc/X11/xorg.conf.d/70-synaptics.conf
Section "InputClass"
    Identifier "My Pad"
    Driver "libinput"
    MatchIsTouchpad "on"
    MatchDevicePath "/dev/input/event*"
shut-down X server, then startx. inspecting the fresh /var/log/Xorg.0.log i see it missed all my synaptic options (needed for horizontal/vertical edge scrolls, etc)

[nick65go]

Yes, xinput works. This I tried first (reading from Gentoo, Archilinux, Xorg(5) manual),  to understand the equvalences xinput <-> synaptics.

Code: [Select]

$ synclient -l

    VertTwoFingerScroll     = 1
    HorizTwoFingerScroll    = 0

        Synaptics Edge Scrolling (309): 1, 1, 1
        Synaptics Two-Finger Scrolling (310):   1, 1
What I try to achieve is an automatic Xorg configuration. This can be done by loading a small driver (xf86-input-synaptics) and its configuration, OR in /home/tc/X.d using a script about xinput + a list of parameters like above.

[nick65go]

Remarks about ALSA. The mydata.tgz (which contains my setings about /etc/modprobe.d/snd_hda-intel.conf) is loaded AFTER the alsa.tcz (and its alsa-module-$kernel.tcz) are loaded from onboot.lst

For me, ALSA without core remastering, can be only in on-demand; because my setting about digital sound before HDMI are useless if alsa.tcz is in onboot.lst

[nick65go]

Remarks about firmware*.tcz: Even if I have listed first firmware*.tcz in onboot.lst, dmesg still shows warning messages about them. Because they are found a little later.

Only remastering the core could suppress them.

Moreover, 3+ processes are running in the background, because firmware triggers like

Code: [Select]

/sbin/udevd --daemonare not stopped later.

[Juanito]

That’s not for certain, the kernel first  looks in the driver for the firmware and then checks elsewhere.
