Fix the Immediate Resume Following Suspend

📅 December 5, 2017
Linux Mint 18.3 was released a few days ago!

Despite being a superb Linux distribution, some fundamental problems remain. One such problem is the suspend/resume feature.

After installing Linux Mint 18.3 MATE, I found that if I assign a keyboard shortcut to suspend the system, the Linux system will go into suspend mode but immediately resume.

Power management issues, such as suspend and hibernation, have plagued Linux systems with a variety of distributions across a variety of hardware that I have tried, but since Linux Mint is my preferred distribution, this it the one I am focusing on.

Windows does not have this problem from my usage. Given the same hardware, I have found that Windows will suspend/hibernate/shutdown without any of the problems that are apparent with Linux, such as blank resume screens (requiring a system reset button press), no resuming, dead hibernation (never waking up), or immediate resumption following a suspend.

This article shows a quick way to fix the suspend issue so that we can assign a keyboard shortcut that will suspend Linux. Pressing the power button on the computer will wake up the system.

VLC – Default Ultra Widescreen Playback

📅 December 4, 2017
“How can I set VLC to automatically scale and crop to fill an ultra widescreen monitor and remove the black bars?”

Video playback on the Acer Predator X34 ultrawide monitor is impressive. Whether it be a home video or a YouTube clip, the extra screen real estate on the sides increases immersion.

However, most videos are 16:9 widescreen, and playing back most content results in vertical black bars on the left and right sides of the video in fullscreen mode.

We can adjust the crop ratio in VLC to 2:39:1 that will fill the video to the entire monitor, but this requires manual adjustment upon each video playback. Is there a way to configure VLC so that it will automatically crop to 2.39:1 when videos are played back?

Yes!

How to Set the Default Monitor Refresh Rate

📅 September 15, 2017
“How can I make Linux Mint default to 100Hz for my fancy ultrawide monitor?”

If you are using a high-end monitor with Linux, such as the Acer Predator X34, that supports refresh rates higher than 60Hz, then you have probably noticed that Linux Mint defaults to a high refresh rate (100Hz if overclocked) at the login screen, but returns to a lower refresh rate (50Hz or 60Hz) after showing the desktop.

Sure, you can change the refresh rate to 100Hz manually using the Nvidia control panel, but this is a minor inconvenience that must be performed upon each boot.

“Is there a way to make the change persistent across reboots so I can always startup with, say, 80Hz?”

Yes. This article shows how to set a default refresh rate in Linux Mint 18.2 with the proprietary Nvidia drivers installed. The change is persistent across reboots. While this article uses the Acer Predator X34 overclocked to 100Hz, the same method should apply to any other monitor if using Nvidia drivers.
