How to Dim Multiple or Individual Monitor in Ubuntu 22.04

Last updated: November 5, 2023 — Leave a comment

Have multiple monitors connected to your Ubuntu 22.04 machine? There’s now an indicator to dim all or individual monitor screen brightness with sliders.

You can dim external monitor brightness with either physical buttons or ddcutil utility. However, an indicator applet in system tray can be more effective, and here’s one for Ubuntu 22.04 with default GNOME 42.

It’s a Gnome Shell extension, that adds a light bulb to top-right corner in panel. By clicking on it, will show you the slider to dim all the connected monitors, as well as individual sliders to dim certain screens.

And, by moving the slider to far right will make the screen totally dark, just like being turned off.

Besides dimming monitor screens, it can also change the colors with RGB sliders, which also can apply to either all or individual monitors.

As my laptop’s external HDMI port is broken, I can’t try out the multi-monitor support. But, the dimming and RGB color (need to at least move dim slider a bit to right) functions are working very well in my case in Ubuntu 22.04 Desktop PC.

My test without multi-monitors

How to Install the Dimming Control Indicator

First, launch Ubuntu Software, then search for and install “Extension Manager” app.

Install Extension Manager in Ubuntu 22.04+

Then, click on top-left ‘Activities’ button to open overview screen, search for and launch ‘Extension Manager’.

When the tool opens, navigate to ‘Browse‘ tab, and finally search and install “VividShade: Multi-Monitor RGB Dimming Control” extension.

The indicator applet will appear on panel immediately after installation.

Uninstall:

To uninstall this extension, also launch “Extension Manager“. Click expand it under first tab, finally click on red “Remove” button.

On kernels with implement features, nvidia-drm will install a framebuffer console when loaded with both modeset=1 and fbdev=1 kernel parameters. Though, when an nvidia-drm framebuffer console is enabled, unloading nvidia-drm will cause the screen to turn off.

Other changes in NVIDIA 545.29.02 include:

  • Experimental HDMI 10 bits per component support
  • Support for virtual reality displays
  • CERTIFIED-quality support for GeForce and Workstation GPUs to open kernelmodules.

How to Perform Stress Test on Your CPU in Ubuntu / Debian

Last updated: June 10, 2024 — 1 Comment

This simple tutorial shows how to do stress test on your CPU in Ubuntu or Debian Linux, either Desktop or Server.

Got a new CPU /CPU cooler, or changed your computer environment? You can perform a stress test to find out if it’s working good! And, here’s how to do the trick in Debian, Ubuntu, and their based systems.

Step 1: Install stress/stress-ng & s-tui

In all current Ubuntu (20.04, 22.04, 24.04) and Debian releases, there are few command line and TUI tools to do the job.

First, open terminal either from start/application menu or by pressing Ctrl+Alt+T on keyboard.


When it opens, run command:

sudo apt install --install-suggests s-tui

Type user password (no asterisk feedback) for sudo authentication and hit Enter.

The command will install s-tui, with TUI interface to start, stop, configure stress test, and monitor your CPU status in terminal.

With --install-suggests option, it also installs the stress or stress-ng package as the backend for the testing.

Step 2: Perform Stress Test

After installing the tool, simply run the command below in terminal to start s-tui:

s-tui

Then, you’ll see something look like the screenshot below shows you.

In left, it shows some options, as well as summaries of core temperatures, and frequencies. In right, it shows information about the temperature, utilization rate,etc in graphs.

To start stress test, just left click on ( )Stress in the top-left corner of terminal, or use arrow key to highlight it and hit Enter. To stop it, just click to switch back ( )Monitor.

By clicking Stress Options in left, it will show you option to set a timeout to automatically stop stress testing in given seconds. You can also change Sqrt() worker count and Sync() worker count to specify how many cores to run for stress test.

Tips 1 : For GNOME, Ubuntu’s default desktop environment, open “Power” settings and change CPU power mode to ‘Performance’ before performing stress test, or your CPU may not run in full speed.

Tips 2: While stress testing, you may also monitor the temperature of other devices (e.g., SSD) in your machine. To do so, you may install ‘hardinfo’ by running command in terminal:

sudo apt install hardinfo

Then open it and navigate to ‘sensors’ tab in left.

That’s all. Enjoy!
