Got a Acer ConceptD 7 Ezel CC715-71P to install Linux and test touch screen on it. After booting from Ubuntu 23.10 USB, the installer told me that I need to deal with the Intel RST settings. Reboot, F2, enter the BIOS setup, but I didn’t find any option related.
Yeah, got a new work laptop recently, MacBook Pro 16″, M3 Max/36GB/1TB. But Asahi Linux is not ready for M3 yet.
And I have VMware Fusion, then I tried a few linux distributions with arm64/aarch64 support.
Assume you have a host(x86_64) build of qtbase, like following:
|
1 2 3 4 5 6 7 |
cd ~/qt git clone git://code.qt.io/qt/qtbase.git mkdir qtbase-build cd qtbase-build ../qtbase/configure -developer-build -opensource -confirm-license -nomake examples -nomake tests -verbose cmake --build . --parallel -j8 |
Some extra work to setup system:
Install Ubuntu 23.10, for me, it’s an VM via VMware Fusion 13.5.0 on MacBook Pro 2019.
Install some needed packages,
|
1 2 3 4 5 6 7 8 |
sudo apt install -y zsh build-essential perl python3 git sudo snap install cmake --classic sudo apt install ninja-build sudo apt-get build-dep qtbase-opensource-src sudo apt-get install libxcb-xinerama0-dev sudo apt-get install '^libxcb.*-dev' libx11-xcb-dev libglu1-mesa-dev libxrender-dev libxi-dev libxkbcommon-dev libxkbcommon-x11-dev sudo apt-get install libdbus-1-dev libglib2.0-dev |
Default gcc/g++ is 13.2.0.
Add following in env:
|
1 2 3 |
export MAKEFLAGS='--jobs=8' export CMAKE_GENERATOR=Ninja |
I normally run several linux vms in VMware Fusion on MacBook Pro 2019. Recently during a trip, the system stuck. I forced a shutdown and reboot. Then I lost network in a Ubuntu 23.04 vm, there is no ethernet interfaces in Network section in Settings(GNOME), and there is no related icon in top-right corner.
I googled a few times, I found one article helped me. Something is wrong in this file:
|
1 2 3 4 5 6 |
sudo cat /var/lib/NetworkManager/NetworkManager.state [main] NetworkingEnabled=false WirelessEnabled=true WWANEnabled=true |
Anyway, I just followed the steps in the article, it works for me.
|
1 2 3 4 |
sudo service NetworkManager stop sudo rm /var/lib/NetworkManager/NetworkManager.state sudo service NetworkManager start |

KDE developers are working hard on Plasma 6 Wayland. See also KDE Plasma 6 Development Progressing Well, Plasma 6 Beta Possible In A Few Months and KDE Plasma 6 Wayland Session: “It’s Been Working Great!”.
For example, you can install Neon Developer Edition via KDE neon: Live Images. After installation, you can upgrade it to KDE/Plasma 6,
sudo apt update
sudo apt install neon-settings-2
sudo apt full-upgrade
See also Neon Unstable now using Qt 6 Builds of Frameworks and Plasma.
If you find any bug, please help to report to KDE bugtracker. Here is my first ticket recently.
With Manjaro(Arch based, Xfce edition), installed as a vm in VMware Fusion on macOS. You can install sway or sway-git.
sudo pacman -S sway
or
git clone https://aur.archlinux.org/wlroots-git.git
cd wlroots-git
makepkg -si
git clone https://aur.archlinux.org/swaybg-git.git
cd swaybg-git
makepkg -si
git clone https://aur.archlinux.org/sway-git.git
cd sway-git
makepkg -si
If you want to use gnome-terminal,
sudo pacman -S gnome-terminal
Modify /etc/sway/config , the line
set $term foot
to
set $term gnome-terminal
Modify /usr/share/wayland-sessions/sway.desktop , the line
Exec=sway
to
Exec=env WLR_NO_HARDWARE_CURSORS=1 /usr/bin/sway
If you want to restart display manager to login again,
sudo systemctl restart lightdm

这个VPS当时安装的是Ubuntu 15.04，非LTS。最近发现很多软件没法装最新版本。想升级吧，系统提示的do-release-upgrade还不行。搜了搜，发现得走这样的路径：15.04->15.10->16.04 LTS。

sudo apt-get update sudo apt-get upgrade sudo do-release-upgrade -d sudo do-release-upgrade |
然后发现系统提示php的包不需要了，就删掉了… 然后我的wordpress就起不来了。继续搜，原来出了php7。

Qt is a huge project, especially like the module, QtWebKit. If you happen to be in a computer farm, it is very useful to use distributed complation to speed up the build of Qt.
Here I suggest to use icecream on Linux and Mac OS X, and IncrediBuild on Windows(at least for Microsoft’s Visual Studio compilers). About IncrediBuild, more details perhaps will be updated in the future. See also qtrepotools: publish ibmake.bat, incredibuild xge wrapper for make/buildconsole.
Today, this blog is more about icecc/icecream.
icecream is maintained by the SUSE people. Then there are less issues in OpenSUSE than in Ubuntu. But Ubuntu is more popular one. I just use Ubuntu as example here.

-no-pch when configure.-arch argument that Qt 4 passes to the compiler confuses icecream. So for now, if you use Qt4, you need to patch your mkspec to not add that (if you build for your local architecture only), eg. in mkspecs/common/gcc-base-macx.conf.(Note: looks like it’s only on Mac OS X, I haven’t tried it yet.)
