Logitech Gaming Software – Mouse not Detected

After installing Karabiner Elements for MacOS I found that the Logitech Gaming Software (LGS) was no longer detecting the mouse and was showing the move mouse to wake dialog.

It took a while to figure out that the cause was the recently installed Karabiner Software, exiting the software allowed immediate recognition of the mouse. Not sure what the cause is and the mouse was functional though not under the LGS command.

A useful tool but not if you are using LGS it would appear.

Dell Display Manager Hotkey

With the Dell Display Manager dmm.exe there are command-line parameters to allow some remote control.

They are as follows:

  ddm.exe /IncControl 10  //to increase brightness

ddm.exe /IncControl 12 //to increase contrast

ddm.exe /DecControl 10 //to decrease brightness

ddm.exe /DecControl 12 //to decrease contrast

The default with no second figure set is 1 or 1% – so in my example I use 5 for 5% like so:

ddm.exe /IncControl 10 5

To increase by 5%

I use the excellent Windows program AutoHotKey, which is free, to do this:

Here is my AutoHotKey script snippet:

#F2::Run "C:\Program Files (x86)\Dell\Dell Display Manager\ddm.exe" "/IncControl 10 5"

#F1::Run "C:\Program Files (x86)\Dell\Dell Display Manager\ddm.exe" "/DecControl 10 5"

This would assign WIN+F2 to Brighten by 5% and WIN+F1 to Dim by 5%


You can also do it with Windows natively using the built in shortcut method:

To create a shortcut using Windows native system Right click on the desktop (or where ever you want it) and chose New > Shortcut then enter the following in the Target: dialog field

"C:\Program Files (x86)\Dell\Dell Display Manager\ddm.exe" "/IncControl 10 5"

and choose the Shortcut you would like to use in the Shortcut key: dialog field. You will need to create two shortcuts; one for Inc and one for Dec.

It should be noted that the Dell Display Manager will need to be started and running in the background.

Mouse Acceleration on MacOS

ExactMouse acceleration killer:

ExactMouse from Steelseries removes mouse acceleration on the Mac.

Acceleration is a a problem for me when using a mouse on any computer that requires precise pointer placement. It is not easy to disable it completely on the Mac without using some fancy terminal command.

To make it easy to disable acceleration either term-rally or permanently you can use the ExactMouse tool from Steelseries. The improvement in general mouse work are subtle but noticeable and improve the feel of high quality gaming mice.

Download from steelseries site.

Turn off Notification Requests in Safari

For some reason Web Browsers such as Safari have added the ability for Web Sites to request the sending of Notifications using the OS notification system. Quite why anyone would want this on 99% of the sites is beyond me.

If you are fed up with constantly having to say no to these requests there is a way to turn off all requests in Safari, and certainly other browsers too.

To turn of the prompts go to:

Settings > Websites > Notifications

and deselect the check box at the bottom of the pane.

 

Windows 10 Drag and Drop Bug

You are going to love this Windows 10 bug: Drag and Drop stops working for me occasionally and I finally found out how to fix it, hit the escape key.

That’s it if you find you can’t drag drop icons in Explorer under Windows 10 try hitting the Escape key once and it should work.

Although it isn’t working for everyone but worth a try 🙂

Another thing worth trying and checking is to run the

sfc /SCANNOW

Options:

SFC [/SCANNOW] [/VERIFYONLY] [/SCANFILE=<file>] [/VERIFYFILE=<file>]
[/OFFWINDIR=<offline windows directory> /OFFBOOTDIR=<offline boot directory> [/OFFLOGFILE=<log file path>]]

/SCANNOW Scans integrity of all protected system files and repairs files with
problems when possible.
/VERIFYONLY Scans integrity of all protected system files. No repair operation is
performed.
/SCANFILE Scans integrity of the referenced file, repairs file if problems are
identified. Specify full path <file>
/VERIFYFILE Verifies the integrity of the file with full path <file>. No repair
operation is performed.
/OFFBOOTDIR For offline repair, specify the location of the offline boot directory
/OFFWINDIR For offline repair, specify the location of the offline windows directory
/OFFLOGFILE For offline repair, optionally enable logging by specifying a log file path

As administrator this will check and repair system files under windows.
