Chrome Remote Desktop 在 Ubuntu (其他 Linux 應該也是)， 預設是開新的 Session ，但是這並不符合我們的使用習慣
1. 先下載這個 use_existing_session.patch patch file ，先上好 patch
2. 執行完之後
執行以下命令並重新啟動 chrome remote desktop service
export FIRST_X_DISPLAY_NUMBER = 0 echo "0" > ~/.config/chrome-remote-desktop/Xsession systemctl restart chrome-remote-desktop@"your_user".service
目前在 Dell Notebook + Ubuntu 22.04 沒有問題，雙螢幕也可以支援
When using Ubuntu ARM64 server to install the server version before installing Kubuntu, the NetworkManager doesn’t work and shows no available networks. Regardless of your attempts to restart NetworkManager or change Netplan configurations, none of them seem to work.
The reason for this issue is that the ‘renderer: NetworkManager’ line is missing from the network YAML configuration file. To resolve this problem, you should edit your YAML file and add the following line.
renderer: NetworkManager
to /etc/netplan/00-installer-config.yaml (my example), then restart network manager will fix it.

If you tried every way on output to Linux kernel, but nothing work. Probably that’s because SPCR(Serial Port Console Redirection Table), and this option default is enable.
Just disable it in your BIOS and add “console=tty0” to /etc/default/grub, then update grub.cfg. it will work.
In AMI BIOS, it should be in the Advanced->Serial Port Console Redirection->Console Redirection
Set it to [Disabled]

The installation process can automatically set up the environment and install Stable Diffusion, which can save a lot of time. However, it requires an NVIDIA or AMD GPU to install it.

Platform is Ampere Altra Mt. Collins system with 2 Ampere Altra CPU, total 160 cores.
OS: ubuntu 22.04.02 LTS
Seems Stable Diffustion webui needs python 3.10, so, ubuntu 22.04 is good choice.
Due to CentOS website document cannot provide a simple instruction to build CentOS 8 stream with some easy steps. So, I make a note to record these procedures about how to build it.
