22.04 The xbox controller of wine has a mistake, how to fix?

6

First of all, I installed wine following the steps from this website without installing about winehq because of this, and also installing more typing these commands:

$ sudo apt-get install wine32

$ sudo apt-get install winetricks

$ winetricks dotnet45

$ export WINEPREFIX="$HOME/.wine"

$ wineboot

I typed the command wine64 uninstaller to add packages:

wine-mono-7.4.0.msi
wine-gecko-2.47.2-x86.msi and wine-gecko-2.47.2-x86_64.msi
.NET-Desktop-Runtime-6.0.10-x86 and .NET-Desktop-Runtime-6.0.10-x64
xi.win7.x86.en.msi (The original driver of my xbox360 joystick)
xi.win7.x64.en.msi (I couldn't install, so repair option instead)

I followed the steps of the xboxdrv's installation from this website to work with my xbox 360 joystick.
I installed open-joystick-display-2.8.0-x64-linux.deb to check the input of my xbox360 joystick:

I installed open-joystick-display-2.8.0-x64-windows.exe by wine to check the input of my xbox360 joystick:

I typed the commands to check the difference between controllers of Ubuntu (left side) and wine (right side):

$ jstest.gtk

$ wine control joy.cpl

I checked that the controller of Ubuntu is working fine, and the controller of wine has a mistake, for example as the above picture that instead of four axes, it's four buttons and besides, the Rz axe is not working at all.

Could anyone tell me how to fix?

How can I remove and purge EasyScreenCast from Ubuntu 20.04?

1

I typed sudo apt remove easyscreencast and I got the result:

    Reading package lists... Done
    Building dependency tree
    Reading state information... Done
    E: Unable to locate package easyscreencast

So anyone can explain me how to remove and purge EasyScreenCast?

Bluetooth USB dongle 5.0 0a12:0001 doesn't work on Ubuntu 20.04

9

WIRELESS USB DONGLE - BLUETOOTH USB DONGLE - MINI 5.0 - VERSION 5.48 - 0a12:0001

So lately I bought a Bluetooth USB dongle - model no: MLT-5.0-MiNi

I'm using Ubuntu 20.04.1 LTS.

1. After I connected the adapter into USB port, I checked the port typing in terminal lsusb and I got the following:

Bus 002 Device 003: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)

2. hciconfig -a gave the following:

hci0:   Type: Primary  Bus: USB

        Link policy: RSWITCH HOLD SNIFF PARK 
        Link mode: SLAVE ACCEPT

3. hcitool dev:

Devices:

So it seemed that my PC didn't have the driver installed.

4. bluetoothctl --version:

bluetoothctl: 5.53

5. rfkill:

ID TYPE      DEVICE      SOFT      HARD
0  bluetooth hci0   unblocked unblocked

6. And finally btmon:

Bluetooth monitor ver 5.53
Failed to bind channel: Operation not permitted

I found this YouTube video to solve the problem.

1. First of all, I had to install the app "Ubuntu Mainline Kernel Installer" to update until the lastest kernel version, so I typed:

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

2. Then, before updating to the last kernel version, I had to check what the running kernel version is:

User@PC:~$ uname -r

5.4.0-48-generic

User@PC:~$ uname -sr

Linux 5.4.0-48-generic

3. Later I went to the website of KERNEL and checked what the last Kernel version that's stable is, for example: 5.8.13

After all, I opened the app Ubuntu Mainline Kernel Installer and clicked the last kernel version that is stable, for example: 5.8.13. Finally clicked the button Install.

4. After the installation and reboot, I checked again:

User@PC:~$ uname -r

5.8.13-050813-generic

User@PC:~$ uname -sr

Linux 5.8.13-050813-generic

I saw that it was successful, and the bluetooth USB DONGLE 5.0 is working.

BUT THERE IS ONE PROBLEM TO CONNECT AFTER PAIRING: After pairing Ubuntu with my speaker 5.0, it cannot connect, then after pairing Ubuntu with my smartphone LG, I couldn't send any pictures to smartphone from Ubuntu nor vice versa.

1. I typed systemctl status bluetooth and entered.

I see that there is a problem:

2. rfkill list:

    Hard blocked: no

I see that everything is OK.

4. btmon:

There is one more problem:

Soundcore Flare+ is the speaker's model. I see there is one another problem:

Unknown type 0xff with 9 bytes data

The Bluetooth USB 5.0 works fine on Windows 10 but on Ubuntu 20.04, it doesn't work. So Ubuntu needs drivers for Bluetooth 5.0.

On 5.8.14 Kernel, Ubuntu really displays devices to pair and connect, but the pairing and connecting don't work.

So, could anyone help me to solve this problem of pairing and connecting with devices from Ubuntu?

I found the problem solved for Linux in this website but I don't know how to compile and patch on Ubuntu 20.04, it can work only for Kernel's version 5.8.

Problem installing Dual Band USB Adapter 2.4/5GHz Wi-Fi on Ubuntu 18.04.4

1

DUAL BAND USB ADAPTER 2.4/5GHz 1200(866+300)Mbps WIRELESS SPEED WITH 802.11ac

So lately I bought Dual Band USB Adapter with the driver on the CD to install on Windows, Mac, and Linux.

I'm using Ubuntu 18.04.4 LTS - 64-bit

1. After I connected the adapter into USB port, I checked the port typing in terminal lsusb and I got the following:

Bus 001 Device 007: ID 0bda:b812 Realtek Semiconductor Corp.

2. sudo dkms status and then I got nothing after that.

3. And then I went to install Wi-Fi 2.4GHz in the folder called ( RTL81888192EUS_linux_v4.3.0.4_11485.20140519 ) that is in the CD, typing in the terminal chmod +x install.sh and then sudo ./install.sh and I got the following result:

It seems that the file rtw_cmd.o does not exist in the folder, therefore it has been failed.

It also seems that the file rtw_cmd.o does not exist in that folder, therefore it has also been failed.

- So could anyone fix the files rtw_cmd.o in both folders of Wi-Fi 2.4GHz and 5GHz, please?

The folders are in the following link: Dual Band USB Adapter Wifi for Linux

Failed to start LSB: SANE network scanner server

1

So my print-scanner Samsung SCX-4300 is working fine through USB, and instead, I connected it with "Networking USB Server" like the following link:

https://es.aliexpress.com/item/Wavlink-USB-2-0-red-LRP-servidor-de-impresi-n-USB-Hub-100-Mbps-compartir-una/32933067390.html

Through the server, the print is working fine but scanner doesn't work, and I followed the instruction of Ubuntu's tutorial:

https://help.ubuntu.com/community/SaneDaemonTutorial?action=show&redirect=sane.d+tutorial

1. So I wrote on the terminal sudo service saned restart:

Failed to restart saned.service: unit saned.service is masked

2. Later, sudo service saned status:

● saned.service
   Active: inactive (dead)
   Loaded: masked (/dev/null; bad)

Then, I research on the internet, and I found this web: systemctl, how to unmask

3. file /lib/systemd/system/saned.service:

/lib/systemd/system/saned.service: symbolic lik to /dev/null

4. I typed to check sudo nano /run/systemd/generator.late/saned.service and I found that there was completely empty.

5. sudo rm /lib/systemd/system/saned.service and then, later, sudo systemctl daemon-reload

7. and finally, systemctl status saned:

How to reset and detect plug-in HDD/SSD via IDE or SATA without rebooting?

So, I'm using my brand new HARD DRIVE CADDY SATA III in CPU.

When I mount the HDD/SSD physically in the mounting bracket, I can click on "Scan for hardware changes" in "Device Manager" of Windows 7 to detect HDD/SSD. Now, how can I do like it in Ubuntu 18.04? I mean how can I detect HDD/SSD without rebooting Ubuntu?

I have three questions that I need to type in Ubuntu's terminal:

What command can I type to detect HDD/SSD via IDE and SATA?
What command can I type to remove plug-in with HDD/SSD via IDE or SATA?
What the best way can I change HDD/SSD physically via IDE or SATA without any problem?
