2023-06-26, Remove Xubuntu

  • sudo update-alternatives --config default.plymouth
  • sudo dpkg-reconfigure lightdm
  • sudo apt remove xfce4-appfinder

Stashed changes

2023-02-22, boot compression

Changed /etc/initramfs-tools/initramfs.conf from COMPRESS=zstd to COMPRESS=xz

Then rebuild the images using

sudo update-initramfs -u -k all

2023-01-31, remove TLP

  • After installing the mainline kernel 6.1.x everything seems more stable
  • TLP does some strange things every now and again.
sudo apt remove tlp tlp-rdw tlpui
sudo apt install power-profiles-daemon

2023-01-10, TLP UI

sudo add-apt-repository ppa:linuxuprising/apps
sudo apt update
sudo apt install tlpui

2023-jan-02, External screen

It is possible to control the brightness of an external screen. First find the names of the screens:

> xrandr -q | grep " connected"
eDP-1 connected (normal left inverted right x axis y axis)
DP-1-0 connected primary 2560x1440+0+0 (normal left inverted right x axis y axis) 600mm x 340mm

Then set the brightness:

xrandr --output DP-1-0 --brightness 0.80

Alternatively install gddccontrol or ddcutil and the gnome extension called Adjust Display Brightness:

2022-dec-30, crashing

Installed kernel 6.0.9 using the mainline tool

sudo add-apt-repository ppa:cappelikan/ppa
sudo apt update
sudo apt install -y mainline

Working afterwards, but reinstalling the nvidia driver:

sudo apt reinstall nvidia-driver-525

2022-dec-28, TLP

TLP will take care of the majority of settings that powertop --autotune would, and with less trial and error, see Powertop.

https://linrunner.de/tlp/installation/ubuntu.html

sudo add-apt-repository ppa:linrunner/tlp # TLP latest
# sudo add-apt-repository ppa:linuxuprising/apps # TLPUI latest
sudo apt update
sudo apt install tlp tlp-rdw
# sudo apt install tlpui
sudo apt remove power-profiles-daemon
sudo apt install acpi-call-dkms

Change the video modes

  • sudo prime-select intel # Good battery, but not functional HDMI
  • sudo prime-select nvidia # Horrible battery, but good HDMI
  • sudo prime-select on-demand # Good battery, somewhat working HDMI
  • sudo prime-select query

The best battery performance yet was archived by using the nouveau driver instead of the proprietary nvidia driver.

Lid suspends the laptop

https://fostips.com/lid-close-action-ubuntu-21-04-laptop/

Edit and uncomment /etc/systemd/logind.conf:

  • #HandleLidSwitchDocked=ignore – If your system is inserted in a docking station, or if more than one display is connected, then the action occurs if specified.
  • #HandleLidSwitchExternalPower=suspend – If your system is on external power, the action occurs if specified.
  • #HandleLidSwitch=suspend – For all other cases, the value of HandleLidSwitch will occur if enabled.

Afterward restart

sudo systemctl restart systemd-logind.service

Powertop suggested recommendation

sudo apt-get remove irqbalance

Brightness control

https://askubuntu.com/questions/1368075/screen-brightness-issues-on-lenovo-legion-5-pro-2021-ubuntu-20-04

If your BIOS is set to dynamic/hybrid mode Edit grub’s config:

sudo vim /etc/default/grub

Change the line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

To:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video.use_native_backlight=1"

Then run:

sudo update-grub

And restart the laptop.
