qbittorrent – Slow download speeds on 18.04

I need help configuring VPN settings in Ubuntu 18.04. It is a new installation yesterday. As for the Internet, everything is intact.

The download speeds in both qBittorrent and Transmission are very low (300 kbs maximum). I have a VPN enabled (VPN.ht), but this is the first operating system that I have such problems. I contacted the Internet provider and the ports that use both applications are open.

In 18.04 LTS, how can you change the TrackPoint driver from libinput to Synaptics?

I want to change the TrackPoint driver from libinput to Synaptics. I am using a ThinkPad X390 and tried the latest version of the libinput driver and tried to figure out why the libinput driver behaves in a way that makes TrackPoint unpleasant for me and now I want to go back to Synaptics until libinput develops further. I have verified that the TrackPoint seems to work fine in 16.04, which has the Synaptics driver.

How could this change be made from libinput to Synaptics in Ubuntu 18.04 LTS?

I have already executed the following:

sudo apt install xserver-xorg-input-synaptics-hwe-18.04 xserver-xorg-input-evdev-hwe-18.04

ppa: every time I try to update my ubuntu I receive this error. Please help me where I am wrong. I am running ubuntu 18.04 LTS

drivers – How to install tensorflow for NVIDIA GPU RTX 2070 SUPER on Ubuntu 18.04

I have been trying to install Tensorflow for my new RTX 2070 Super. I have been following the following instructions:

Steps

verify that the system has a gpu with capacity cuda

download and install the nvidia cuda toolkit and cudnn

configure environmental variables

verify installation

# #

If you have a previous installation, remove it first.

sudo apt-get purge nvidia*
sudo apt remove nvidia-*
sudo rm /etc/apt/sources.list.d/cuda*
sudo apt-get autoremove && sudo apt-get autoclean
sudo rm -rf /usr/local/cuda*

to verify that your gpu is enabled for cuda

lspci | grep -i nvidia

The gcc compiler is required for development using the cuda toolkit. to verify the version of gcc install enter

gcc --version
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install g++ freeglut3-dev build-essential libx11-dev libxmu-dev libxi-dev libglu1-mesa libglu1-mesa-dev
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-key adv --fetch-keys http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/7fa2af80.pub
echo "deb https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64 /" | sudo tee /etc/apt/sources.list.d/cuda.list

# installation of CUDA-10.0

sudo apt-get -o Dpkg::Options::="--force-overwrite" install cuda-10-0 cuda-drivers
echo 'export PATH=/usr/local/cuda-10.0/bin:$PATH' >> ~/.bashrc
echo 'export LD_LIBRARY_PATH=/usr/local/cuda-10.0/lib64:$LD_LIBRARY_PATH' >> ~/.bashrc
source ~/.bashrc
sudo ldconfig

wget https://developer.nvidia.com/compute/machine-learning/cudnn/secure/v7.5.0.56/prod/10.0_20190219/cudnn-10.0-linux-x64-v7.5.0.56.tgz
tar -xzvf ${CUDNN_TAR_FILE}
sudo cp -P cuda/include/cudnn.h /usr/local/cuda-10.0/include
sudo cp -P cuda/lib64/libcudnn* /usr/local/cuda-10.0/lib64/
sudo chmod a+r /usr/local/cuda-10.0/lib64/libcudnn*
nvidia-smi
nvcc -V

pip3 install –user tensorflow-gpu == 1.13.1

However, when I write nvidia-smi I get the following:
NVML initialization failed: driver / library version does not match

I also tried to download the latest NVIDIA driver (440.35) but I did not succeed in running the .run file. He kept giving me a message that said "The preinstallation script provided by the distribution failed!"

Any help would be very much appreciated!

Where exactly have I landed in the mpich installation process, after installing the package for ubuntu 18.04

I am installing the software stack in an Ubuntu 18.04 cluster of 8 boxes. Following scripts / tutorials like I / m I am not an IT professional. My script told me to install mpich using sudo apt-get install mpich, but then abandoned me to the Installer Guide for v 3.3.1 on the mpich.org website. The Guide assumes that you are installing from the source and have to compile, etc. And I don't have the knowledge to deduce with sufficient confidence what specific section or instructions of the Guide I should implement next.
that is, what is my landing site, in the Guide, after the installation of the Ubuntu package?
My purpose is only to give the cluster to a local school, as an IT interest stimulator. Therefore, my goal for the applications is some ready-to-use mpich demo programs, eventually to run the Intel Linpack HPC performance application and perhaps enable Python (the most common language taught in the sixth grade universities of the Kingdom United).
Can a kind person point me to the landing site or someone who can talk to this rookie pilot?

pulseaudio – The media have no sound and the videos are very slow Ubuntu 18.04

the sound and videos were fine, but after connecting my HDMI cable (note, I have a Mac book, so I use a special plug) the media started to have no sound (my Mac book has sound and I can play games, the audio works fine but listening to music on Spotify and watching tube videos, that's the problem) I restarted my audio pulse and checked the sound in the settings, but I can't find the problem.

ubuntu 18.04 – Babel 6.26.3 is still installed instead of version 7.7

I am configuring a new server (Ubuntu 18.10), and I can't seem to install the latest Babel. I'm doing:

apt-get -y install npm
sudo npm install -g babel-cli
npm install --save-dev @babel/core
npm install @babel/cli
npm install @babel/preset-env
npm install --save @babel/polyfill

However, when I look at the version, it tells me that I am only in version 6.26.3 (it is not what I want, since some of the add-ons I need depend on version> 7.0, therefore, rebuild the server)

Any suggestions on what to try?

TO UPDATE: I'm not sure if this is related, but for some reason the server has 2 instances of npm, with quite different versions:

root@east:/home/steampunkdev/web/xxx.net/node_modules# /usr/bin/npm -v
5.8.0
root@east:/home/steampunkdev/web/xxxx.net/node_modules# /usr/local/bin/npm -v
6.13.0

UPDATE 2: I wonder if maybe I am missing a source for the latest version. This is what I have in sources.list:

deb http://mirrors.linode.com/ubuntu/ cosmic main restricted
deb http://mirrors.linode.com/ubuntu/ cosmic-updates main restricted
deb http://mirrors.linode.com/ubuntu/ cosmic universe
deb http://mirrors.linode.com/ubuntu/ cosmic-updates universe

deb http://security.ubuntu.com/ubuntu cosmic-security main restricted
deb http://security.ubuntu.com/ubuntu cosmic-security universe
deb http://security.ubuntu.com/ubuntu cosmic-security multiverse

I can see version 7.7.2 here: https://www.npmjs.com/package/@babel/core, but mine doesn't seem to want to install that version: /

Ubuntu 18.04 Nvidia driver dell 5593 10th gen processor does not work

I installed ubuntu 18.04 next to windows 10 on dell 5593 with Intel 10th gen processor and nvidia mx230.
I couldn't start in ubuntu because I didn't have the nvidia driver installed and the basic driver had problems with the hdaudio codec. I managed to boot into rescue mode and installed nvidia-435 successfully.
The newest driver I found in the repository was nvidia-435 and ubuntu now boots up, however, I can see in nvidia-smi or even details of the system that doesn't work (it shows Graphics: llvmpipe (LLVM 8.0, 256 bits)).
One of the problems I found at the ATM does not work the brightness adjustment.
Is it related to the fact that I have an Intel 10th gen processor and is not fully compatible with Ubuntu 18?
I found topics that suggest changing the grub file, but none of the solutions worked.

18.04 – How Thunar in detail list view?

I am running Ubuntu 18.04. I would like to configure Thunar to always show a detailed list view. I can open Thunar, go to preferences and configure the current instance to show detailed views of the lists. But then, when I restart and open Thunar, the default icon view returns. It seems that in 16.04 there were Gnome settings to handle this kind of thing.

I would like to configure Thunar permanently so that it always shows detailed lists. How do I force Thunar to see the detailed list in beyond the current desktop?
