Cinnamon on Fedora offers solid theming options through the official repositories. Here’s a practical approach to building a cohesive desktop environment with matching window borders, icons, controls, and cursor themes. Installing Theme Packages Start by installing available theme packages from the Fedora and Cinnamon repositories: sudo dnf install cinnamon-themes cinnamon-control-center sudo dnf install papirus-icon-theme adwaita-icon-theme…
On a Linux system, you often need to let regular users mount and unmount specific devices without requiring sudo or the root password. This is common for external drives, USB devices, or secondary internal disks. There are several approaches, each with different security and usability tradeoffs. Using /etc/fstab with the user Option The simplest approach…
Linux Mint’s Cinnamon desktop automatically mounts removable media like USB drives and external hard drives by default. If you prefer manual control over when and how storage devices are mounted, you can disable this behavior through Nemo, the Cinnamon file manager. Disable Auto-Mounting via Nemo Preferences The simplest approach is to configure Nemo’s mounting behavior…
If you’re running Google AdSense on your site, you might want to show ads only to desktop visitors and hide them on mobile devices. This reduces clutter on smaller screens and can sometimes improve user experience—though test your bounce rates to confirm it actually helps your metrics. Using CSS Media Queries The cleanest approach is…
When you start a QEMU guest without explicitly configuring VNC, the display server may not bind to an address your VNC client can reach. You’ll see an error like: vncviewer: ConnectToTcpAddr: connect: Connection refused Unable to connect to VNC server This happens because QEMU defaults to SDL display output and doesn’t automatically expose VNC to…
Linux Mint defaults to graphical mode, but you can boot directly to the console if you prefer a text-only environment or need to troubleshoot display issues. There are two main approaches: using GRUB parameters or disabling the display manager entirely. Method 1: Add the text kernel parameter (GRUB) This is the quickest approach and keeps…
Emacs doesn’t restore your cursor to the last editing position by default—Vim does this out of the box. Fortunately, save-place-mode is built into Emacs and requires minimal configuration to enable this behavior. Basic Setup Add this to your ~/.emacs.d/init.el: (save-place-mode 1) That’s all you need. The mode automatically saves your cursor position when you close…
The simplest way to see your commit history as a tree structure: git log –graph –oneline This produces a text-based graph showing branch relationships and merges with abbreviated commit hashes: * b5dc8b9 Merge branch ‘main’ into develop |\ | * 7514ef1 revised the README.md | * 6692428 align size to page for both shalloc and…
When you’ve modified your keyboard layout or key bindings using xmodmap and need to revert to the default, setxkbmap is your primary tool. However, the approach depends on whether you’re running X11 or Wayland, and what aspects of the configuration you want to reset. Check Your Session Type Before attempting any resets, verify whether you’re…
Remapping space to Ctrl while preserving space on tap is useful for modal editors and power users. The challenge: distinguish between a held key (Ctrl) and a quick tap (space). Kernel-level remapping can’t do this, so you need userspace solutions. Quick Comparison of Methods Tool Best For Pros Cons keyd Simplicity, both X11 and Wayland…
You can use @import with media queries to conditionally load CSS files only for specific viewport sizes. This is useful for loading layout-specific stylesheets, web fonts, or icon libraries only when needed. Basic Syntax The general format is: @import url(‘path/to/file.css’) media-query; The media query parameter controls when the stylesheet loads. Here are practical examples: /*…
Exit codes are how programs communicate success or failure to the shell and parent processes. Understanding them is essential for writing reliable scripts and debugging applications. Linux and Windows handle these differently, so knowing both conventions matters if you work across platforms. Linux Exit Codes On Linux, the convention is simple: 0 means success, 1–255…
GNOME 3 removed the GUI option for customizing window title fonts that existed in earlier versions. The setting is still configurable, but you’ll need to access it through command-line tools or configuration editors. Using gsettings (Command Line) The simplest approach is gsettings, which directly modifies the configuration: gsettings set org.gnome.desktop.wm.preferences titlebar-font ‘Sans Bold 10’ To…
LightDM is a lighter alternative to GDM (GNOME Display Manager). If GDM is causing issues, you prefer a simpler login screen, or you’re running a lightweight desktop environment, here’s how to switch to LightDM on Fedora. Install LightDM sudo dnf install lightdm lightdm-gtk-greeter The lightdm-gtk-greeter provides the graphical login screen. Other greeter options include: lightdm-gtk-greeter…
Cinnamon is a modern, feature-rich desktop environment forked from GNOME. It’s lightweight compared to full GNOME installations and offers a traditional taskbar-based interface. Installing it on Fedora is straightforward. Basic Installation Use dnf (the modern package manager) with group install: sudo dnf groupinstall ‘Cinnamon Desktop’ This installs the complete Cinnamon desktop environment along with necessary…
When you start a VNC server with the -geometry flag under GNOME 3, you’ll notice the display resolution doesn’t match what you specified: vncserver -geometry 1024×768 This works fine with GNOME 2 and window managers like twm, but GNOME 3 ignores the setting. The actual resolution will be whatever was last used in that session,…
Chrome supports proxy configuration via command-line flags, which is useful for scripting, automation, or testing without touching the GUI settings. This works across all major Linux distributions. Basic proxy configuration Use the –proxy-server flag when launching Chrome: google-chrome –proxy-server=”socks://localhost:8080″ Proxy scheme formats The proxy specification follows this format: [<proxy-scheme>://]<proxy-host>[:<proxy-port>] Supported schemes: http — HTTP proxy…
GNOME can automatically restore your session—reopening all applications and windows that were running when you last logged out. This differs from autostart scripts, which launch specific programs on every login regardless of what was running before. Automatic Session Restoration To enable automatic session restoration in GNOME: Open Settings → General (or search “Session” in Activities)…
Controlling a GNOME desktop remotely—locking the display, activating the screensaver, or blanking the screen—requires you to interact with the running GNOME session. The approach depends on your GNOME version and what you’re trying to accomplish. Using systemd User Sessions and D-Bus Modern GNOME (3.30+) uses systemd user sessions and D-Bus for session management. The older…
GNOME uses .desktop files in ~/.config/autostart/ to launch applications when you log in. This mechanism works across GNOME, XFCE, KDE, and most other modern desktop environments. Basic Setup Create a .desktop file in ~/.config/autostart/. Here’s a minimal example: [Desktop Entry] Type=Application Name=My Autostart Script Exec=/home/user/bin/myscript.sh Save this as ~/.config/autostart/myscript.desktop and it will run on your…
