Install Q4OS in x64 chromebook braswell hardware

protonpedro · 2020-04-28 17:26

Its possible install and configure Q4OS in a acer chromebook R11.

in my old laptop the Q4OS is running 1000 time better than any distros with 1.2GHz CPU and 4GB ram.

My chromebook has 16GB storage but i can use my files in a SDCARD and gdrive.

I'm trying make it boot i can go fort terminal log in in failsafe alternative.

Any help.

You should read up on Mr Chromebook and installing a custom firmware. I'm running Galluim here but have loaded the firmware which is much more like a PC BIOS and suspect I may be able to install Q4OS on my C720 at some point...

As cpcnw said, with Mr. Chromebox firmware you should be able to run q4os on it, and then you'll need a few files from Chrome/GalliumOS in order to make the sound work. I'm MODERATELY certain the Braswell drivers are in the 4.19 kernel.
I'm actually doing the same with my HP Chromebook 13G1, running q4os Trinity.

OK decided to load Q4OS on my Acer C720 Peppy Chromebook. Sound works out of the box. I need to get the touch pad two finger scroll / tapclick working and the keyboard top row keys.

Any tips guys!

ps Perhaps we should have a top level thread for Chromebooks because I suspect that during Covid-19 lockdowns this [Linux on CB] is becoming a popular past time!

I have enabled 'Chromebook' keyboard in (Control Centre > Regional & Accessibility > Keyboard Layouts)

as well as GB Keyboard so I get £ (GB Pounds) currency. I'm missing the brightness and volume up/down keys.

Just tested the Webcam works fine

But... no battery charge / state indicator...

Looks like I have a bit of work to do

If you use Trinity, you need to install "tdepowersave-trinity" package.

cpcnw · 2020-05-12 10:32

Any tips on the keyboard / touchpad?

Tnx

You could try to modify the "/etc/X11/xorg.conf.d/60-libinput.conf" configfile

cpcnw · 2020-05-12 12:26

Funnily enough that's exactly what I was doing when I noticed your post;

On GalliumOS which uses the synaptics driver you can use two fingers in the middle of the touchpad to scroll entire page up/down

On Q4OS which uses libinput you can only scroll up/down on the far right of the touchpad - think this is referred to as edge scrolling

I was also able to get two finger scrolling working by modifying /etc/X11/xorg.conf.d/60-libinput.conf
One needs to change Option "ScrollMethod" "edge"
to Option "ScrollMethod" "twofinger"
After changing "edge" to "twofinger" and saving one can scroll using two finger rather than edge scrolling.

@wove - works perfectly - so that's the touchpad sorted

Now it's just the keyboard and I am happy

q4osteam · 2020-05-12 14:22

You could try to install packages:
kmilo-trinity
kmilo-legacy-trinity

Nope still struggling with keyboard. In web browser Back Forward Refresh all work. This is just by selecting gb and chromebook layout.

I have looked though /usr/share/X11/xkb/symbols/inet in the chromebook section and the ones specified above make sense however sound and brightness are the two things I need. I had a quick look at kmilo but couldn't make sense of it. If I knew how to map keys I could pass amixer commands for sound at least and have a look into xbacklight?

cpcnw · 2020-05-12 18:11

Have tried adding the GalliumOS xkb files as outlined in this post [bottom of 4th from bottom]

https://www.reddit.com/r/GalliumOS/comm … g_miniiso/

which gives me a lot more choice in versions of Chromebook model keyboard layouts but alas still does not work for brightness / audio

Interestingly one of the layouts makes the 'full screen' key invoke the lockscreen

cpcnw · 2020-05-12 19:54

If I use xev I can see that the keystrokes actually create the correct events

KeyRelease event, serial 39, synthetic NO, window 0x3a00001,
    root 0x10f, subw 0x0, time 2637782, (-192,594), root:(955,615),
    state 0x0, keycode 73 (keysym 0x1008ff02, XF86MonBrightnessUp), same_screen YES,
    XLookupString gives 0 bytes:
    XFilterEvent returns: False

KeyPress event, serial 39, synthetic NO, window 0x3a00001,
    root 0x10f, subw 0x0, time 2641354, (-192,594), root:(955,615),
    state 0x0, keycode 72 (keysym 0x1008ff03, XF86MonBrightnessDown), same_screen YES,
    XLookupString gives 0 bytes:
    XmbLookupString gives 0 bytes:
    XFilterEvent returns: False

I installed xbacklight which didn't work until I edit /etc/default/grub with

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"

and

udevadm info -a -p /sys/class/backlight/intel_backlight/

  looking at device '/devices/pci0000:00/0000:00:02.0/drm/card0/card0-eDP-1/intel_backlight':
    KERNEL=="intel_backlight"
    SUBSYSTEM=="backlight"
    DRIVER==""
    ATTR{max_brightness}=="937"
    ATTR{type}=="raw"
    ATTR{bl_power}=="0"
    ATTR{actual_brightness}=="937"
    ATTR{brightness}=="937"

cat /sys/class/backlight/intel_backlight/brightness
937

xbacklight works with

xbacklight -inc 20

I can now go into Regional & Accessibility and create appropriate Input Actions for Bightness Up / Down

Brightness control works great however the audio incremental is odd

amixer sset Master 5%+

works from cli as does reducing the voume but from the keyboard it only creates one reduction up or down of 5% and that's it?

pactl set-sink-volume @DEFAULT_SINK@ +5%

also only works the one key press?

This what I ended up with for the audio

Mute: amixer -D pulse set Master 1+ toggle
Up: pactl set-sink-mute @DEFAULT_SINK@ false ; pactl set-sink-volume @DEFAULT_SINK@ +5%
Down: pactl set-sink-volume @DEFAULT_SINK@ -5%

and after a couple of reboots and messing about it suddenly just started working properly!

So thats it I have screen brightness and volume keys as well as Alt-F Keys!

You could also try to install "klcddimmer-trinity" - a brightness control panel applet, and configure it to use "xbacklight" as backend.

Hello I installed Q4OS KDE on an entry level Aspire-A115-31 Intel Celeron N4000 4g ram laptop and frankly I'm very satisfied with it, fast, smooth and a flawless installation.

Salutation! Cyberbleuet
