Are you sure about your math? If you're in there, you might mention that all values are normalized WRT 1. It's easier to see the point of c1 and c3's equations if you have that fact in mind. Also, for cases where the touchscreen area is a subset of the screen area, these coefficients need to be negative. Thanks for the most useful article on X's transformation matrices that I could find!
This document is amazing, I created a google docs calculator to build the command for me. Sportpeppers talk21 April UTC.
This page is now showing only the hard way. As the header says, the two pages need merging.
But the hard way is still relevant when xrandr cannot identify the separate screens because they've been merged into one large screen. I worked out a very messy way of recalibrating. Here's my notes on how to do it manually:. The matrix should be 1. We now need to calculate four values, called "a", "c", "e", and "f" reference. Test the values with the following command replace a, c, e, and f with your calculated numbers :. The touchscreen should be calibrated now. If not, you can undo the calibration with this reset command:.
Determine which udev device corresponds to your panel. Try each mouse device until you see your panel. Zootboy talk31 January UTC. Zootboy 's description, above, was essential for me getting to a working calibration.
This should use all four points. Reinderien talk18 July UTC. I've found that instead of creating a udev rule step 9 abovethe transformation matrix can also be set permanently through an xorg. This can be achieved by setting the "TransformationMatrix" option on the input class.
Change "MatchProduct" to match your touchscreen device name, and use the correct values for a, c, e, and f. Mogwai talk12 February UTC. Apart from that, it works for me. It sets the calibration immediately by calling xinput needs to be installedand also outputs the contents of the xorg conf file.
If anyone wants to build on it, or include it in some AUR package or whatnot, please go ahead. This is my first time commenting on the wiki.This document describes the differences between XInput and DirectInput implementations of the Xbox Controller and how you can support XInput devices and legacy DirectInput devices at the same time.
XInput is now available for game development. This is the new input standard for both the Xbox and Windows. There are several advantages to using XInput over DirectInput :.
However, some functionality provided by XInput will be missing from the DirectInput implementation:. The combination of the left and right triggers in DirectInput is by design. Games have always assumed that DirectInput device axes are centered when there is no user interaction with the device.
However, the Xbox controller was designed to register minimum value, not center, when the triggers are not being held. Older games would therefore assume user interaction. The solution was to combine the triggers, setting one trigger to a positive direction and the other to a negative direction, so no user interaction is indicative to DirectInput of the "control" being at center.
By supporting XInput only, your game will not work with legacy DirectInput devices.

XInput will not recognize these devices. When enumerating your DirectInput devices, all DirectInput devices will enumerate correctly. You will need to determine which of your DirectInput devices are legacy devices, and which are XInput devices, and remove them from the enumeration of DirectInput devices.

Skip Submit.In computing, DirectInput is a legacy  Microsoft API for collecting input from a computer user, via input devices such as the mousekeyboardor a gamepad. It also provides a system for action mapping, which allows the user to assign specific actions within a game to the buttons and axes of the input devices.
Microsoft introduced a new input library called XInput specifically for the Xbox controller.
While DirectInput forms a part of the DirectX library, it has not been significantly revised since DirectX 8 — Microsoft recommends that new applications make use of the Windows message loop for keyboard and mouse input instead of DirectInput as indicated in the Meltdown slideshow and to use XInput instead of DirectInput for Xbox controllers.
DirectX included DirectInput from version 1. It initially offered true support only for joysticks, as the mouse and keyboard modules simply provided wrappers to the standard Win32 API. DirectX version 3. DirectX 5. Mouse support also increased the number of buttons seen from four to eight. In DirectX 7. DirectX 8. While Microsoft initially intended that DirectInput would handle all inputs, it hasn't turned out this way.
As of [update] Microsoft doesn't recommend using DirectInput for keyboards or mice, and has started pushing the newer XInput for Xbox controllers. XInput,  an API for "next generation" controllers, was introduced in December alongside the launch of the Xbox This instruction set provided full support for Xbox controllers in Windows XP SP1 and subsequent operating systems, and is described by Microsoft as being easier to program for and requiring less setup than DirectInput.
XInput is compatible with DirectX version 9 and later. None of these limitations exist if using the Xbox Controller with XInput. Vibration effects will not work on the Xbox One Controller. Games have always assumed that DirectInput device axes are centered when there is no user interaction with the device.
However, the Xbox controller was designed to register minimum value, not center, when the triggers are not being held. The above, however, ignores the fact that many DirectInput controllers, such as gamepads with dual analog sticks and racing-wheel controller sets, already map triggers and pedals independently.
In addition, many DirectInput devices also have vibration effects. At least one driver, XBCDgives the Xbox controllers the vibration support, dead zones and optionally independent triggers through DirectInput.
On the other hand, Xbox controller and XInput support only very basic control of vibration motors   in contrast with great palette of various effects supported by DirectInput. In XInput 1.

Ask Ubuntu is a question and answer site for Ubuntu users and developers. It only takes a minute to sign up. To ensure the correct one is selected, please use the device ID, or prefix the device name with 'pointer:' or 'keyboard:' as appropriate. I can use the ID instead, but the problem is that the ID of course changes between startups, so I can't makes this automatic simple script that on startup sets sensitivies for all my pointing decvices.
So, is it possible to remove the duplicate device, make xinput ignore it or still refer to the device by it's name? If neither of these are possible, then I guess a script would have figure out the IDs and from those, it seems to be always the smaller one.

Ask Ubuntu is a question and answer site for Ubuntu users and developers. It only takes a minute to sign up. This question has been asked many times with no answer. I've used my basic Google skills and haven't come across a fix. This is system wide. My mouse simply scrolls too fast. I'm new to ubuntu and linux in general. Is there a terminal code I can enter? I removed the USB dongle that comes with my wireless mouse and plugged it back and fixed my scrolling speed instantly.
The higher the value is, the more you divide the acceleration. Acceleration is maximum for a value equal to 1. The "basis" value seems to be 1. To permanently set the change : A hidden file in your directory is ". Copy paste the previous command at the end. That's it! The only thing that worked for me was using some parts of this project. Now you can set your scroll-speed with the following xinput commands source :.
Changing the 8 to a lower value increases the sensitivity. Flipping it to negative changes the direction of scroll. Increasing the value decreases sensitivity. I have written a simple script which allows you to find which device has this property The script basically iterates over all xinput devices and lists only those which have any property containing scroll.
Aside from all of these You can use the old good synaptics dirver for this Yeah I know it is not supported anymore but lets be honest libinput documentation sucks hard. If you are on The default number is 26 the lower the number it is faster to scroll, the higher it is slower to scroll. Finally it should look like this:. My problem was slightly different and I'm posting the answer here to assist other users as well.

My issue was that the default mouse hardware added by VmWare Fusion or Workstation was not supporting scrolling in Ubuntu and other Linux distros, while the cursor was moving. The issue seemed at first to be erratic scrolling, slow scrolling which lead me herewhile in fact, it was a different problem. This thread help me fixed it.
The problem with this mouse in Linux Ubuntu is that the sensitivity is very high. I also don't like mouse acceleration, so I've made a script that turns this off. The script looks like this. Another problem with the G mouse is that it shows up as two different devices in xinput.
This is most likely because the mouse has a wireless adapter, and is usually also connected via a usb cable for charging. This is my output from xinput --list see id 11 and 12 :. This isn't usually a problem, since the id's are usually the same. But sometimes the id's of the mouse change, and that's where my question comes in. Then you loop over the IDs and execute the three xinput commands. If the device name is always the same, in this case Logitech G Laser Mouseyou can search for matching device IDs by running.
Currently I am working on a script for a question over at askubuntu. If everything is OK, script exits silently, with exit status of 0or 1 if any xinput command failed. You can uncomment print statement to show which ids are being configured to later double check with xinput that values are set alright. Next we simply loop over each one of them, and of each one we set all the property-value pairs that are defined in props dictionary.
Could be done with list of tuples as well, but dictionary is my choice here. Learn more.
