My-Personal-Tweaks

This is my pc/laptop personal tweaks and fixes for longer battery life and maximum performance.

Since i am using Linux, i use powerTDP; a great tool to monitor the battery life.

Disable GPU

fu** nVidia!, since it never worked on linux and i struggled to fix this, i've decided to disable that trash.

$ lspci | grep "VGA"

   01:00.0 VGA compatible controller: NVIDIA Corporation TU117M (rev a1)
   05:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Renoir (rev c7)

List installed display drivers and make sure that nivida drivers are not there: NOTE: mhwd is manjaro only! $ mhwd -li

> Installed PCI configs:
--------------------------------------------------------------------------------
                  NAME               VERSION          FREEDRIVER           TYPE
--------------------------------------------------------------------------------
           video-linux            2018.05.04                true            PCI

Make sure to use : nouveau.modeset=0 in the grub, just in case if something went wrong.

Sometimes ScreenTearing and flickering happens

To fix Tearing :

Create this file and use TearFree, to fix tearing problem touch /etc/X11/xorg.conf.d/20-amdgpu.conf

Section "Device"
	Identifier "AMD"
	Driver "amdgpu"
	Option "TearFree" "true"
EndSection

To fix Flickering :

For now i don't have a clue how to permanently fix it, since i am sure what exactly the reason for this (i think it's the new amd gpu, which is kernel related):

Fix (run multiply times): xset dpms force off

Keyboard

I like using my keyboard, so i have a lot of keybinding, check out my wm

one thing, i don't use CAPS lock key(vim), instead it's now esc : setxkbmap -option caps:escape

Poweroff

change the power button handler #HandlePowerKey=poweroff to ignore to prevent accidental presses:

$ vim /etc/systemd/logind.conf

powertop

Install powertop to monitor battary usage. further modification :

• create a service to run at start up

  sudo touch /etc/systemd/system/powertop.service

	[Unit]
	Description=Powertop tunings

	[Service]
	Type=oneshot
	ExecStart=/usr/bin/powertop --auto-tune

	[Install]
	WantedBy=multi-user.target

• enable it sudo systemctl enable powertop.service

mounting other partitions

use fstab or in case of not authorized to perform this operation :

create a rule on polkit:

group : id

/etc/polkit-1/rules.d/49-nopasswd_global.rules

/* Allow members of the wheel group to execute any actions
 * without password authentication, similar to "sudo NOPASSWD:"
 */
polkit.addRule(function(action, subject) {
    if (subject.isInGroup("wheel")) {
        return polkit.Result.YES;
    }
});

can't change the brightness

1. Install light : sudo pacman -S light
2. Run it as sudo without password by editing the sudoers file : sudo visudo -f /etc/sudoers
3. Add this : none ALL=(root) NOPASSWD: /path/to/light
4. Change the command to run with sudo in the sxhkd

Fix clipboard issues

1. Install a clipboard manager : parcellite
2. Make sure to run it : Parcellite by default runs as daemon.
3. ProTip : make sure to run flameshot also
4. ProTip : neovim uses xclip
