There is a bug that appears intermittently. Touchpad can become lost and unresponsive after wake from suspend. A workaround is to unload and reload the touchpad kernel module.
sudo modprobe -r i2c_hid_acpi i2c_hid && sudo modprobe i2c_hid_acpi i2c_hid
You can automate the process using the sleep hooks (more infos here: https://wiki.archlinux.org/title/Power_management#Sleep_hooks just look the part of "root-suspend" and "root-resume" services). Basically when the laptop suspends, you have to unload "i2c_hid_acpi" and "i2c_hid", and when it wakes up you have to reload them.
Here is my /etc/systemd/system/root-suspend.service:
[Unit]
Description=Local system suspend actions
Before=sleep.target
[Service]
Type=simple
ExecStart=-/usr/bin/modprobe -r i2c_hid_acpi i2c_hid
[Install]
WantedBy=sleep.target
and here is /etc/systemd/system/root-resume.service:
[Unit]
Description=Local system resume actions
After=suspend.target
[Service]
Type=simple
ExecStart=/usr/bin/modprobe i2c_hid_acpi i2c_hid
[Install]
WantedBy=suspend.target
To enable them on boot, just do:
sudo systemctl enable --now root-suspend.service && sudo systemctl enable --now root-resume.service
It happens that if you do intensive tasks (for example you are in a videocall with your webcam on while you are recording the screen and doing other stuff) the laptop starts to lag until if freezes. I noticed that this happens ONLY if it is charging, so I guess that the temperatures go too high due to the charging and so it lags. Maybe the availability of RAM is related too.
Some users reported that editing the file /etc/default/grub, specifically the line GRUB_CMDLINE_LINUX_DEFAULT, adding idle=nomwait iommu=pt as boot parameters, it solves the issue:
GRUB_CMDLINE_LINUX_DEFAULT="idle=nomwait iommu=pt"
after you edited the file you have to update the grub, it should work by doing:
sudo grub-mkconfig -o /boot/grub/grub.cfg
If the issue does not fix, I suggest you:
- When you do intensive tasks and you notice the lag, you have to unplug the charger.
- Increase the swap partition size
Wifi can disconnect sometimes randomly. It happens because there is a buggy software that doesn't know how to properly change from 2.4GHz to 5GHz and viceversa. The "solution" that I found is to manually set the wifi network we are connected to in 2.4Ghz OR in 5GHz... this way it doesn't switch between 2GHz and 5GHz. This is doable with your network manager in the settings of your DE.
No automated program like tlp, powertop, laptop-mode-tools, auto-cpufreq, etc improves the battery in this laptop in my experience. For some reason, Linux Mint has lowest power consumption compared to other distros... however, after some research and testing, I created a bash script that do some tweaks to put more things possibile in power saving mode, and have the best result in terms of power consumption. You have to install ryzenadj and zenstates to run this.
#!/bin/bash
sleep 15 &&
echo 5 > /proc/sys/vm/laptop_mode &&
echo 0 > /proc/sys/kernel/nmi_watchdog &&
echo 1 > /sys/module/snd_hda_intel/parameters/power_save &&
echo Y > /sys/module/snd_hda_intel/parameters/power_save_controller &&
#echo 1 > /sys/devices/system/cpu/sched_mc_power_savings &&
#echo ondemand | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor &&
echo powersave | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor &&
echo 1500 > /proc/sys/vm/dirty_writeback_centisecs &&
echo powersave > /sys/module/pcie_aspm/parameters/policy &&
#echo powersupersave > /sys/module/pcie_aspm/parameters/policy
#for i in /sys/bus/usb/devices/*/power/autosuspend; do echo 1 > $i; done &&
#for i in /sys/bus/pci/devices/*/power_level ; do echo 5 > $i ; done 2>/dev/null
ryzenadj -a 15000 -b 30000 -c 20000 --power-saving &&
echo battery > /sys/class/drm/card0/device/power_dpm_state &&
echo manual > /sys/class/drm/card0/device/power_dpm_force_performance_level &&
echo 2 > /sys/class/drm/card0/device/pp_power_profile_mode &&
echo 0 > /sys/devices/system/cpu/cpufreq/boost &&
zenstates --disable -p 0 &&
zenstates --disable -p 1
You can create a systemctl service that starts on boot (for example /etc/systemd/system/pwrsavinggg.service):
[Unit]
Description=pwrrrrrsavingggggggg
[Service]
Type=simple
RemainAfterExit=yes
ExecStart=/home/user/pwrsaving.sh
[Install]
WantedBy=multi-user.target
and then enable it with:
sudo systemctl enable --now pwrsavinggg.service
If you want to obtain the best performance, here is a bash script to do so:
#!/bin/bash
echo 0 > /proc/sys/vm/laptop_mode &&
echo 0 > /sys/module/snd_hda_intel/parameters/power_save &&
echo N > /sys/module/snd_hda_intel/parameters/power_save_controller &&
echo performance | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor &&
echo 1500 > /proc/sys/vm/dirty_writeback_centisecs &&
echo performance > /sys/module/pcie_aspm/parameters/policy &&
ryzenadj -a 45000 -b 45000 -c 45000 --tctl-temp=90 --max-performance &&
echo performance > /sys/class/drm/card0/device/power_dpm_state &&
#echo high > /sys/class/drm/card0/device/power_dpm_force_performance_level &&
echo manual > /sys/class/drm/card0/device/power_dpm_force_performance_level &&
echo 5 > /sys/class/drm/card0/device/pp_power_profile_mode &&
echo 1 > /sys/devices/system/cpu/cpufreq/boost &&
zenstates --enable -p 0 &&
zenstates --enable -p 1
Fan can be loud sometimes, and they can't be controlled via software (with Windows neither), so the best you can do is to follow the Power Saving paragraph.
Fingerprint driver has been reversed engineered succesfully :D so you are finally to use fingerprint also on Linux!! Open source world is amazing.
You have to flash a firmware for your fingerprint, and then install a package. Further information in Discord channel here: https://discord.gg/XATKTUfX7M in the cannel #5110 (this is the ID of fingerprint device in this Matebook computer). If your PC isn't exactly the one of this repo, you can check for your fingerprint device ID number writing sudo lsusb -vd "27c6:" | grep "idProduct" in a terminal
