Abhishek Kamal's questions

Most of the time, I use these git commands :

• git add src/ package.json
• git commit -m "custom message"
• git push origin "name_of_the_branch"

So I want to make a single alias command which should look like:

git_alias src/ package.json && "custom message" && name_of_the_branch    

By running the above alias, it should run all three git commands (add, commit and push).

How can I do this?

Note

I know that I can make alias for any command (in this case, git commit) as follows:

alias gc='git commit -m '

I always use mpv media player to play media files (video/audio).
But I want that "whenever I open a video/audio through MPV, it should be by default mute".
I tried to add cycle mute to the last line of input.conf file.
But it didn't work.

Because of slow speed on youtube-dl and after reading this discussion I am trying to use yt-dlp (current version : 2021.12.27).
But when I run yt-dlp https://youtu.be/qIX1BhvUMJ0 I am getting error. Error is given below :

I don't know what is this. Please help me.

so I tried to customize my KDE desktop using Latte dock and some other tools, but then I didn’t like it because it started to break my desktop and a lot of bugs. So, how can I reinstall KDE Plasma without having to do a fresh installation of Kubuntu ? Thanks.

Note :

OS : Kubuntu 21.10
Plasma version : 5.22.5
KDE frameworks version : 5.86.0
Qt version : 5.15.2

I have also tried rm .kde/share/config/kdeglobals but nothing changes and I don't have plasma-* in .kde/share/config/plasma-*.

I also already removed latte-dock and kvantum-manager

My laptop has 4GB Nvidia GeForce GTX 1650.
I am using dual boot (Ubuntu 21.04 + Windows 10).
Today I used a command -

sudo ubuntu-drivers autoinstall

After it I reboot my laptop and choose for boot with Ubuntu from Grub menu. But my laptop is not booting with Ubuntu now. Continues with black screen and a white blinking cursor at the top left corner.

What should I do ?

I am using Kubuntu 21.04. I just update (not upgrade) Kubuntu from default software-center. After a successful update, I tried to access my local files stored in another drive (128GB), but that drive is now empty. It had around 128GB data in it. Not only this, after this update, my all data stored in /home/abhishek/ (13GB) and /var/www/html/(50GB). was gone(may be deleted or something else). My desktop settings and themes are also gone. I am using dual boot (Kubuntu + Windows 10). I restarted my PC and logged back in but unfortunately, Result is still same.

I was also working in a project, but I cannot find it now.

Is there any method to get this data back?

Edit 3:

Output of /var/log/syslog

Edit 4:

I had 50GB of data in /var/www/html/ which is the location of PHP projects and 12.9GB approx data in /home/abhishek/. I wondered why am I not able to see my data in /var/www/html/, /home/abhishek/ and ``/dev/nvme0n1p4` and why my system-settings has reseted, themes deleted, chrome sign-out. One more things when my update process was running, after 1 minute, Kubuntu hangs, So I restarted my laptop.

Eg, I was enabled tap-to-click with touchpad, but now tap-to-click is not working because I have to re-enable it again.

I just installed Kubuntu 21.04. I am using dual boot (Windows10 + Kubuntu). Kubutnu takes around 20 secs to shut down. Boot time is 3-4 seconds fast because of SSD. Problem is only with Kubuntu while shutdown. It takes long time.
For the solution, I go to this askUbtunu link, but I don't have sendsigs file in /etc/init.d/.

Why does it so ?

I brought a new Asus laptop which has latest WI-FI 6. I installed Kubuntu 21.04 alongside Windows 10 (dual boot). Furthermore, I can use both Ethernet and WI-FI in Windows, but I can only use Ethernet in Kubuntu. There is no wireless connection option is showing in networking options.
The same problem encountered when I was using Deepin OS in this laptop.

How to solve the problem ?

EDIT 2 :

I follow command line steps and downloaded Linux kernel 5.12.8 (1,3,4,6 line *.deb) to install kernel 5.12.8 which support WI-FI 6.

I reboot my laptop and it first shows
to select kernel version. (As by default it selected that kernel which I just installed). I hit enter, and then it shows

What should I do now ?

I am currently using the mpv media player in Kubuntu 21.04. To rotate the video by keyboard, I edited the ~/.config/mpv/input.conf file and added:

r cycle_values video-rotate 90 180 270 0

Now, whenever I play a video with mpv and press r, the video will be rotated by 90 degrees, as shown in the image below:

However, this also changes the aspect ratio after rotating by some degrees.
You can see the default image of this video without any rotation at this time below:

There was no issue when I was using mpv before in elementary OS.
This issue came up when I started using Kubuntu.

How can I solve this problem?

I had no problem when I was playing HD videos (greater than 720P, even 4K too) in Ubuntu 19.10.
I have just Installed Ubuntu 20.04 and trying to play HD videos, but video starts lagging and CPU uses goes to 100% while playing HD videos. I always use mpv video player to play all kind of videos
I am using Dell Inspiron 5559 Intel core i3 6th gen, RAM 4GB, Inbuilt skylake graphics.
(I think my laptop's information isn't neccessary for this question because in previous versions of Ubuntu, upto 4K videos was playing smoothly).
What's in my mind for this problem -
I think it is due to the high CPU uses.

I am fond of Ubuntu Unity version and this is the first time when I am using gnome with the Ubuntu, and I found that minimize action is disabled by default so I enabled it by using gsettings set org.gnome.shell.extensions.dash-to-dock click-action 'minimize' then I opened nautilus (file manager) then i click on other locations on left menu bar then two new icons (bottom two as given in image) of my two paritions came on my launcher so when I try to minimize one of the window of my partition, a new nautilus window comes instead of minimize.
I am trying to minimize the window by clicking on second bottom icon given in below image.
You can see the two extra dots shown on nautilus icons and its partion.

I am using Ubuntu 20.04 and I think this bug (yes I think this is the bug) isn't specific to only this version.
and can anyone tell me that why Ubuntu-gnome always comes with the disabled window minimize action ?
As Ubuntu has stopped delivering the Amazon app then Why Ubuntu is not delivering with already enabled the minimize action of window ?

I am currently using Ubuntu 19.10 with the unity DE and I always use mpv to play videos in Ubuntu. As mpv has few GUI options, there is no GUI option to rotate a video, but we can rotate it with the help of the command line. For example, we can rotate a video by 90 degrees using the command below:

mpv --video-rotate=90 /home/guest/new_vdo.mp4

This way (using the terminal) however, I have to type the command every time I want to rotate the video.

How can we create a keyboard shortcut to rotate a video which is currently playing in mpv?

I always use mpv video player to play all types of video formats
In my laptop ( dell inspiron 5559 core i3 ), 4k videos of dimension 3840 x 2160 (of 30fps) were playing very smoothly with mpv video player yet . But today I reinstall Ubuntu 18.04, after installation complete, I again install mpv using the command sudo apt install mpv

and 'mpv' installed successfuly but now I found that 4k videos (of 30fps) are not playing smoothly.

• I always use mpv video player to play all types of video formats.
• I never ever use 'vlc' to play 4k videos or hd videos because every time mpv done that job very smoothly.
• may be i missed some packages for videos.
• I tried to play 4K videos with other players like (mplayer, gnome-mpv, and ubuntu default player) but no one play 4K videos smoothly.
• 4K videos were playing properly before i did reinstall .

What is the problem ?, i am very upset to face such kind of problems ?

Today I opened gnome-terminal and I wrote

ls && sleep 4 && gnome-terminal

to open another terminal after the completion of ls command and waiting for 4 seconds.
So it successfully opened a new terminal after previous commands completely ran (including sleep 4).

After that, next time I typed a new command

ls -lR && sleep 4 && gnome-terminal

The command ls -lR completed after 3 seconds, but after that none of the commands sleep 4 and gnome-terminal ran successfully.

What is the problem?
