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.

Disable the default ABC keyboard layout:

Change the current input source to your custom keyboard layout.
Open ~/Library/Preferences/com.apple.HIToolbox.plist (in 10.9) or ~/Library/Preferences/ByHost/com.apple.HIToolbox.*.plist (in 10.8 and earlier). You can convert the plist to XML with plutil -convert xml1.
Remove the input source or input sources you want to disable from the AppleEnabledInputSources dictionary. If there is an AppleDefaultAsciiInputSource key, remove it.
Restart.
