Ubuntu password set a short one, disable length check

sudo apt-get purge libpam-pwquality

Then: sudo passwd <user name>

Don't use the Settings UI to change it because the UI will check the length too.

On Ubuntu 22.04/24.04, SAML authentication from GlobalProtect doesn't open the default browser

The problem was that ~/.config/mimeapps.list doesn't have the correct setting for type text/html=. It should be set to text/html=microsoft-edge.desktop or your chosen browser.

How do I install the NVIDIA drivers for RTX A6000 GPUs on Ubuntu 22.04?

Installing NVIDIA drivers for the RTX A6000 on Ubuntu 22.04 requires a few key steps to ensure optimal performance and compatibility. The RTX A6000 is a powerful data center and workstation GPU, and proper driver installation is essential for machine learning, AI, and high-performance computing workloads.

Prerequisites

Ubuntu 22.04 LTS installed and updated (sudo apt update && sudo apt upgrade -y)
RTX A6000 GPU properly installed in the system
Internet connection for downloading drivers
Administrative (sudo) privileges

Step-by-Step Installation Guide

1. Disable Nouveau Drivers (Open-Source Alternative)

Nouveau drivers can conflict with NVIDIA's proprietary drivers. Disable them by running:

Open a terminal and create a new blacklist file: sudo nano /etc/modprobe.d/blacklist-nouveau.conf

Add these lines:

blacklist nouveau
options nouveau modeset=0

Save the file (Ctrl+O, then Ctrl+X).
Update the initramfs: sudo update-initramfs -u
Reboot the system: sudo reboot

2. Install NVIDIA Drivers via Ubuntu Repository

The simplest method is using Ubuntu's built-in repository:

Open a terminal and update the package list: sudo apt update
Install the recommended NVIDIA driver (usually the latest stable version): sudo ubuntu-drivers autoinstall
Alternatively, manually select a driver version: sudo apt install nvidia-driver-535 (replace 535 with the latest version)
Reboot the system: sudo reboot

3. Verify Installation

After rebooting, confirm the driver is working:

Run nvidia-smi to check GPU status and driver version.
Check the NVIDIA settings panel: nvidia-settings.
Verify CUDA compatibility if needed: nvcc --version (requires CUDA Toolkit).

Alternative: Install Drivers from NVIDIA Website

For the latest drivers directly from NVIDIA:

Visit NVIDIA's official driver download page and select the RTX A6000 and Linux 64-bit option.
Download the .run file.
Make it executable: chmod +x NVIDIA-Linux-x86_64-*.run
Run the installer: sudo ./NVIDIA-Linux-x86_64-*.run
Follow on-screen prompts and reboot.

Troubleshooting Tips

If the system boots to a black screen, try switching to a virtual terminal (Ctrl+Alt+F2) and reinstalling drivers.
Use sudo apt purge nvidia* to remove existing drivers before reinstalling.
Check logs for errors: dmesg | grep -i nvidia.

Following these steps ensures your RTX A6000 operates at peak performance on Ubuntu 22.04, whether for AI training, 3D rendering, or high-performance computing tasks.

Ubuntu 22.04 won't upgrade to 6.8 kernal even after sudo apt install linux-generic-hwe-22.04 ran

If the Ubuntu 22.04 is stuck at 5.15 kernal, make sure the following setting is correct.

It turned out that the Software & Updates need to subscribe to All Updates.

Install nvidia driver 535 on Ubuntu 22.04

For some reason, Nvidia driver 510 and 470 couldn't be install on Ubuntu 22.04 because the installation failed in the last compiling step. Installing driver 535 fixed that issue. To install 535:

sudo add-apt-repository ppa:graphics-drivers/ppa

sudo apt update

Then install.

Debug Ubuntu system

Reading package lists... Done

Building dependency tree

Reading state information... Done

Some packages could not be installed. This may mean that you have

requested an impossible situation or if you are using the unstable

distribution that some required packages have not yet been created

or been moved out of Incoming.

The following information may help to resolve the situation:

The following packages have unmet dependencies:

libcairo2-dev : Depends: libcairo2 (= 1.16.0-4ubuntu1) but 1.16.0-4ubuntu1ppa1 is to be installed

Depends: libcairo-gobject2 (= 1.16.0-4ubuntu1) but 1.16.0-4ubuntu1ppa1 is to be installed

Depends: libfontconfig1-dev (>= 2.2.95) but it is not going to be installed

Depends: libfreetype6-dev (>= 2.1.10) but it is not going to be installed

E: Unable to correct problems, you have held broken packages.

sudo apt-cache policy libcairo2

After the system is fixed: sudo apt install ubuntu-desktop to recover all missing components

Ubuntu shotcuts hijacked

Ctrl+Alt+B 被占用

Ctrl+Alt+S 被占用

Ctrl+Alt+D 被占用

Ctrl+Alt+T 被占用

Ctrl+Alt+左键被占用

gsettings set org.gnome.desktop.wm.keybindings switch-to-workspace-left “[‘disabled’]”

Ctrl+Alt+Right 被占用

gsettings set org.gnome.desktop.wm.keybindings switch-to-workspace-right “[‘disabled’]”

输入法相关快捷键

如Ctrl+Alt+B和Ctrl+Alt+S,这个隐藏的比较深,基本是通过搜索引擎找到的答案.

Ctrl+Alt+S 快捷键从命令行输入fcitx-configtool命令,进入控制面板.

选择第二个tab Global Config,勾选右下角Show Advanced Options,然后从上到下看一下,哪些快捷键被占用,把哪个禁用掉.

Ctrl+Alt+B是选中Tab的Addon,然后勾选左下角的Advanced,滚到最底下,将Virtual Key Board 取消选中即可.
