First time installed Ubuntu, I can see the are two option for CTRL+Print Screen which are screenshot and screen recording. However after installing and upgrading other softwares, the screen recording is missing.
The quick solution apparently just simple as
sudo apt reinstall gstreamer1.0-pipewire
Running FFMPEG with NVIDIA is blazing fast! Here is a quick way on how to install and make it run on NVIDIA and Ubuntu. First of all, if you have Ubuntu 24.10, you need to downgrade to 24.04. The reason because several libraries is not ready on the latest Ubuntu version.
Here is the steps
sudo apt-get install build-essential yasm cmake libtool libc6 libc6-dev unzip wget libnuma1 libnuma-devsudo apt-get update -qq && sudo apt-get -y install \
autoconf \
automake \
build-essential \

zlib1g-dev2. Install FFMPEG needed libraries
sudo apt-get install nasm libx264-dev libx265-dev libnuma-dev libvpx-dev libfdk-aac-dev libopus-dev libdav1d-dev3. Install NVCC version 12
https://developer.nvidia.com/cuda-downloads
4. Compile and Install
cd ~/Downloads/
git clone https://git.videolan.org/git/ffmpeg/nv-codec-headers.git
cd nv-codec-headers && sudo make install && cd -git clone https://git.ffmpeg.org/ffmpeg.git ffmpeg/
./configure --enable-nonfree --enable-cuda-nvcc --enable-libnpp --extra-cflags=-I/usr/local/cuda/include --extra-ldflags=-L/usr/local/cuda/lib64 --disable-static --enable-shared
make -j 8
sudo make installDone!
I have ASUS motherboard that support both 2.5G and 10G LAN Network. Connected with CAT6 with 10Gbps capacity. However, the default Ubuntu limit the transfer speed into 100Mbps.
To solve this problem, here are few steps to do
/etc/default/grub and add this exampleGRUB_CMDLINE_LINUX_DEFAULT="usbcore.autosuspend=-1 quiet splash pcie_aspm=off ipv6.disable=1"
Make sure to reboot your Ubuntu OS.
2. Check your network speed using sudo lshw -c network
sudo lshw -c network
*-network
description: Ethernet interface ...
size: 1Gbit/s
capacity: 1Gbit/s
*-network
...
size: 100Mbit/s
capacity: 1Gbit/s
Its showed here that my second LAN being capped by 100Mbit/s
3.Here is what I’ve learned. Your LAN will follow the other-side LAN speed. In my case, my PC is 2,500 mbps while my another side is 10,000 mbps. So, instead of make changes on my PC, actually go to another side and adjust it to follow yours!
I got to my workstation
sudo ethtool -s enp36s0f0 speed 2500 duplex full autoneg onThen, I disconnect and re-connect. Finally the speed is changed. The biggest learning here is to change another side configuration, not your own 2.5G
I found issue where stutter and nvidia-smi took long time to print, which is unusual. After digging more, apparently this is caused by service of persistence mode.
To solve this, you can disable by comment /lib/systemd/system/nvidia-persistenced.service
sudo vim /lib/systemd/system/nvidia-persistenced.servicesystemctl edit nvidia-persistenced.serviceTo run persistence on your session
sudo nvidia-smi -pm 1 When using Flameshot in Ubuntu Oracular Oriole, its return error : “Unable to capture the screen” Flameshot error. This is persistent whether you are using APT, snap or flatpak.
The quick solution is to modify the launcher and add a simple command. I’m using APT, so I will edit the launcher from ehre
sudo vim /usr/share/applications/org.flameshot.Flameshot.desktopThen edit the execution
[Desktop Entry]
...
Keywords[es]=flameshot;screenshot;capture;shutter;captura;
Keywords[de]=flameshot;screenshot;Bildschirmfoto;Aufnahme;
Keywords[pt_BR]=flameshot;screenshot;captura de tela;captura;shutter;
Exec=flameshot
Icon=org.flameshot.Flameshot
Terminal=false
Type=Application
....Change the execution to be
Exec=sh -c -- "flameshot"This shall fix your problem without any need to disable Wayland and others things. Enjoy!
After installing ASDF in Ubuntu 24.04 and execute gem install, I got error message that no version for ruby, despite I already have it installed.
~/ ruby --version
No version is set for command ruby
Consider adding one of the following versions in your config file at
ruby 3.0.4
The quick solution is to set the global version of ruby or NodeJS (if you have similar problem). Check with asdf current
asdf current
nodejs ______ No version is set. Run "asdf <global|shell|local> nodejs <version>"
ruby ______ No version is set. Run "asdf <global|shell|local> ruby <version>"
Then you can fix this problem by assign asdf global to your installed ruby version
asdf global ruby 3.0.4Mounting Obsidian Vault in google drive using GNOME online account option will not working. The reason because the files in Nautilus cryptic with hash names (literal how Google Drive store our files) without context translation (this part is missing). Also, using this approach the files usually being stream rather persist.
Alternatively, mount GDrive using google-drive-ocamlfuse` solved this problem. Here are 4 quicksteps to do it.
google-drive-ocamlfusesudo add-apt-repository ppa:alessandro-strada/ppa
sudo apt-get update
sudo apt-get install google-drive-ocamlfuse2. Enable your Google Drive API (important!)
Go to https://console.cloud.google.com/apis/api/drive.googleapis.com and enable API.

If you wish to install a non-Debian-packaged Python package,
create a virtual environment using python3 -m venv path/to/venv.
Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make

note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.

Next, running the zeppelin, go to interpreter and configure SPARK_HOME path on both spark and spark-submit settings. Don’t forget to setup the python path as well. Hope this solve your problem!
