- Reason for low battery life in linux
|
|
When a computer is sold with Windows installed, it has ACPI and chipset drivers that can manage the CPU power and overall power consumption. These generally do not exist for Linux, so when the CPU is idle, it is still running the CPU clock at full speed. Similarly, there may be a temperature controlled fan that is dependent on some driver that Linux does not have, so the fan runs at full speed continuously.
|
|
Some computers are supported by Linux and will not exhibit this behavior, but by no means is that true in all cases. I am guessing you have one that is not fully supported by Linux for power management. It may just be a matter of finding the right drivers and installing them. Or the driver may not be available for Linux at all.
|
|
Things are quite a bit better than when I started out with Linux in 1992, but by no means are manufacturers making Linux drivers available for all the hardware out there. Some do, and if you are primarily interested in Linux on a notebook computer, you need to search out manufacturers that either offer Linux as an option or offer the ability to obtain hardware specific Linux drivers.

- Compressions
|
|
When comparing the various compressions, generally the tradeoff is time vs. size. gzip tends to compress and decompress relatively quickly while yielding a good compression ratio. bzip2 is somewhat slower than gzip both in compression and decompression time, but yields even greater compression ratios. LZMA has the longest compression time but yields the best ratios while also having a decompression rate outperforming that of bzip2.

|
for black png to gray png
|

- GPU and i/o usage at xfce panel
|
|
1. First download these third party plugins ie `radeontop` for amd gpu, `nvidia-smi` for NVIDIA GPUs and `iotop` for disk usage.
|
|
2. Make sure that `xfce4-genmon-plugin` is installed. if it isnt then install it.
|
|
3. Now in xfce panel , right click -> panel->add new items->generic monitor.
|
|
4. After adding right click on this new item and add command for displaying the output.
|
|
Command is `radeontop -d - -l 1 | grep -Po "(?<=gpu )([0-9]*\.\d\d\%)"`
|
|
`(?<=<pattern>)` this will exclude the gpu part
|
|
5. But this command directly wont work. so write a script in .sh file and include its path in command section.
|
|
```bash
|
|
#!/bin/bash
|
|
gpu_percent=$(radeontop -d - -l 1 | grep -Po "(?<=gpu )([0-9]*\.\d\d\%)")
|
|
|
|
echo " $gpu_percent"
|
|
```

|
|
`sudo cpupower frequency-set -g powersave`
|
|
also to disable usb auto suspend go to `micro /etc/tlp.conf` and change `USB_AUTOSUSPEND` to 0 and `remote_pm_on_bat` to on instead of auto and finally do
|
|
`sudo tlp start`

- Changing mirrors
|
|
Go to `/etc/pacman.d/mirrorlist` and add mirror like

```
|
|
After copying mirror link append `stable/$repo/$arch`. First in the mirrorlist have most priority as priority order is from top to bottom.
|
|
Use this site to get list of mirors:

|
|
new_resource_path="/home/hpes/Videos/imp/joplin_bkps/joplin-04-03-24/joplin notion extension/_resources/"
|
|
|
|
# Set the file extension you want to process (assuming it's .md)
|
|
file_extension=".md"
|
|
|
|
# its the base path from where relative path is defined.
|
|
# eg: if base path is '/home/user/downloads' and asset is in
|
|
# /home/user/assets' then relative path assigned would be '../assets'
|
|
BASE_DIR="/home/hpes/Videos/imp/joplin_bkps/joplin-04-03-24/joplin notion extension/Web Development/"
|
|
|
|
# Function to resolve relative paths
|
|
resolve_relative_path() {
|
|
local file_path="$1"
|
|
local base_path="$2"
|
|
echo "$(realpath --relative-to="$base_path" "$file_path")"
|
|
|
|
|
|
}
|
|
|
|
# Loop through all .md files in the current directory and its subdirectories
|
|
find "${BASE_DIR}" -type f -name "*${file_extension}" -print0 | while IFS= read -r -d '' file; do
|
|
# Resolve relative paths in the file
|
|
resolved_old_path=$(resolve_relative_path "${old_resource_path}" "$(dirname "${file}")")
|
|
resolved_new_path=$(resolve_relative_path "${new_resource_path}" "$(dirname "${file}")")
|
|
|
|
# Update the relative paths in the file using sed
|
|
sed -i "s|${resolved_old_path}|${resolved_new_path}|g" "${file}"
|
|
# echo "${resolved_old_path} ${resolved_new_path} " "${file}"
