Mice are conceptually one of the simplest device drivers in the Linux operating system. Not all mice are handled by the kernel; rather, there is a two-layer abstraction. The kernel provides services for mice that cannot be driven directly by the user libraries and applications.
That is, mice other than serial mice. It also handles the sharing of mouse services with the X Windows user interface. However, most mice use a common protocol called the bus mouse protocol. Each read from a bus mouse interface device returns a block of data. The first three bytes of each block are defined as follows:. An application can choose to read more than 3 bytes. Some mice send device-specific information in the rest of the block, while in others any additional bytes read will be zero.
Since the value does fit into a byte, it is not allowed. The buttons are numbered left to right as 0, 1, 2, 3, and so forth. Each button sets the corresponding bit in the first byte of the block, with bit 7 always being set. So, if the left and right buttons of a three-button mouse are depressed, the value read back will be 0x85 in binary.
How to Install Additional Drivers in Ubuntu
Indeed, most applications use polling to wait for mouse events to occur. This is a topic we have not yet covered, but which I will explain after looking at a simple mouse driver. First we will need the initialization functions for our mouse device Listing 1. The ports will be the X position, the Y position, and the buttons in that order.
The idea is to have a single device the so-called "misc" device with a single major device number, out of which multiple minor device numbers are allocated. Linux normally parcels out devices by major number, each of which has minor devices associated with it; however, for things like mice this is extremely wasteful, since these drivers only require a single minor number. Use of the misc device allows different drivers to share a single major device number.
This kernel file also carries instructions for registering a device. This may change over time so it is a good idea to obtain a current copy of this file first. Our code then is fairly simple. We check that nobody else has taken our address space. Having done so we reserve it to ensure nobody stomps on our device while probing for other ISA bus devices; such a probe might confuse our mouse. Then we tell the misc driver that we wish to own a minor number.
The file operations work exactly like the file operations you would register for a normal character device. The misc device itself is simply acting as a redirector for requests. Next, in order to be able to use and test our driver we need to add some module wrapper code to support it.
In our case it simply calls the initializing function we wrote and returns an error if this fails. This ensures the module will only be loaded if it was successfully set up. Next we need to fill in our file operations Listing 3. That makes for a simple structure. Nothing special is needed here. We provide functions for the required operations and little else. It maintains a count of the number of times the mouse is open. This is because we do not want to request the interrupt multiple times.There was a time when setting up a Linux system meant you'd spend hours tracking down and installing the right drivers for your hardware.
In modern versions of the OS, like Ubuntu Unless your computer is packed full of state of the art, bleeding-edge hardware, most things should work as soon as you install the operating system. Normally, the only time you need to install or reinstall something like a USB mouse driver is when you're using a nonstandard mouse with extra features.
You won't typically find an Ubuntu mouse driver or Linux mouse driver for an everyday, run-of-the-mill mouse. That's because standard USB mouse drivers are "baked in" to the operating system and handled by the OS's display server.
In Ubuntu, the keyboard and mouse drivers are served by X Windows, just as they are in most other versions of Linux. There's a newer display server called Wayland, which is used by default in Fedora and available on Ubuntu, but it's not quite ready for prime time, so it's mostly used by developers and early adopters.
In each case the mouse driver's code is built right in, so you won't be randomly uninstalling and reinstalling it. That will only happen if you're using a high-end mouse that requires a custom driver. Because Linux mouse drivers are part of the OS, you probably won't find a custom driver from the mouse's manufacturer. It takes time and money to make and maintain one, and Linux gamers are a pretty small market niche, so there's not much motivation for companies like Logitech or Razr to make their own.
Instead, those drivers usually come from projects within the Ubuntu or Linux community, ideally — though not always — with some degree of support from the manufacturer in the form of technical data. The driver is often packaged as a personal package archive, or PPA, which makes it easy to install from the command line.
It'll also be automatically updated after it's installed, which is a great convenience. To reinstall your mouse using a custom driver, the first thing you need to do is tell Ubuntu where to find the PPA. To do this, you need to have administrator privileges at least temporarily, so each command will start with "sudo" to make you a superuser, and you need to enter your password to execute the command. This gives you administrator privileges, gives the command to add a repository, and then tells your computer to use the stable version of the driver from that source.
Once you've added the PPA, type "sudo apt update" to find the new software and then "sudo apt install openrazer-meta" — again, always without the quotes — to install the driver. Once you're done, restart the computer.
The details will vary, depending which driver you're installing, but the process is much the same. You should find the installation directions for your specific driver on the project's web page. If the driver's creators haven't set it up as a package archive, you'll likely see it offered as a file with the. Those files can be used by Ubuntu or any other OS based on Debian, which is one of the main versions of Linux.
The big advantage of a PPA over a. They come as part of a PPA, but with a. The "dpkg" command leaves you to do those individually, but the "gdebi" command does it automatically, so it's the better option for most users.
First, download the. Be careful about which sites you trust for this because if the website is shady, you may end up with malware in addition to a driver. Once the driver is downloaded, type "sudo gdebi nameofdriver. Type "sudo apt install gdebi-core" and then when gdebi is installed, repeat the command to install the mouse driver.
Ask Ubuntu is a question and answer site for Ubuntu users and developers. It only takes a minute to sign up. I use Ubuntu Sometimes, however, I unplug all of them and move the laptop and keep using it with the builtin keyboard and screen and touchpad. At random times it happens that the touchpad stops working but if I plug the usb mouse, the usb mouse does work.
Though this happens very rarely, when it does it's a great annoyance, as I'm forced to reboot if I need the touchpad to work again. Is there some workaround that I can try, such as killing some process that would automatically restart, or some command that would cause the touchpad driver to restart or refresh or something?
Anything that may "wake up" the touchpad without having to reboot? Notably, the switch did not help to turn it back on. I just became careful not to press it, and before long I took to using an external wireless keyboard with integrated wireless touchpad, and I haven't had that problem since. Having only just now learned that the comments remain only temporarily and are automatically deleted, I'm reposting the content of the useful comment below that it may be preserved for others:.
I was sharing the "solution" that worked for me. Today it occurred to me to google for solutions more closely fitting your original question and found the following link.
It isn't what I would personally consider "convenient", but it could at least be more elegant by making it a script out of it. I found this see below — gyropyge Sep 25 at First, open a terminal, and print out all input devices to find the id you need for the input device you want to disable.
In terminal, type:. You want to find the device id that corresponds to the input device you want to disable Maybe something that sounds like "touchpad". Then replace X in the following command with the id number representing the input device you want to disable:. Note: If you're not sure which device id you should use to disable the touchpad, then you can find out by testing random id's and seeing if your mouse pad still works.
Save all your work and be prepared to restart your computer if you do something like disable your keyboard. You may have trouble trying to enable it again if you can't type into the terminal. Reason: I desperately needed an answer to this problem because the problems I was experiencing with my touchpad made doing any kind of work impossible. Suddenly, at some random moment when using my laptop, for apparently no reason, my touchpad goes into some kind of "special mode".
Merely moving one finger on my touchpad would cause the screen to scroll, instead of actually moving the cursor of the mouse on the screen so it was impossible to get the mouse to hover over anything in broswer without considerable coordinating efforts to account for the scrolling screen and non moving mouse.
On the plus side, resetting the touchpad with the method above actually fixes my problem. Update: To make resetting the touchpad even easier, I made a hotkey for the above listed commands. Quick and easy. Finally, you need to give the permissions to make this file executable; run this command with your working directory in the terminal as your home directory where you created the file :.
It still works fine other than that, but it's incredibly annoying, and makes the computer feel really slow. It appears to happen frequently after a sleep, but it sometimes happens when the computer has just booted up. A reboot usually fixes it. I would like to find a way to "reset" my mouse, without having to reboot.
Is there anything else I should try?
How to Reinstall USB Mouse Drivers in Ubuntu Using the Command Line
The optical mouse on my laptop running Ubuntu First I tried the normal quick remedies that is unplugging and re-plugging first on the same port and then on the other two unused ports; the mouse still didn't work. I have to point out that I still had power on the USB ports. So I was puzzled and decided to check what was happening on my terminal. Here are my interactions with the system. At this point I decided to do a web search to see what that specific error means and that's how I landed on this page.
I however felt that the solutions provided needed too much work and instead opted to see what else I could do with the Kernel modules to solve the problem.
First I checked what specific kernel modules were loaded by running. Please note that the proper way of getting loaded modules is by running lsmod but I prefer the method I used above for minute tasks for which I have no use for lsmod 's much more verbose output.
A module name psmouse caught my eye and I decided to test whether reloading both both usbhid and psmouse resurrects my mouse. Also you may have different IDs, they can be obtained by executing:. Try using a different USB mouse. Plug the mouse into another port. You may want to try updating the system.
If you are willing to try anything to fix the issue, once you know it is an issue with the OS you may want to install Ubuntu on your system instead of Kubuntu. Kubuntu is different from Ubuntu, although they are largely the same OS. Sign up to join this community. The best answers are voted up and rise to the top. Home Questions Tags Users Unanswered. Restart USB mouse driver?
Asked 7 years, 6 months ago. Active 7 months ago. Viewed 25k times. I've tried: unplugging and replugging the mouse. I am running Kubuntu You sure it does'nt happen on Windows right?
Probably related to something in the kernel like timers not coming out of suspend right, not a specific problem with the mouse. Check dmesg output.How to Reinstall USB Mouse Drivers in Ubuntu Using the Command Line
Possible, I guess, although it resets itself after a reboot most times. I don't have windows, so I can't test, unfortunately. Even if I did, the problem isn't regular, so it might be difficult to know.Brief: Ubuntu provides an easy way to find and install proprietary drivers. This quick tutorial shows you how to install additional drivers in Ubuntu including Nvidia proprietary drivers.
How do you install drivers in Ubuntu? The simple answer is that Ubuntu itself identifies and installs drivers on your system. But there is a catch.
Some hardware components have several drivers available: open source ones and the proprietary ones. By default, Ubuntu installs the open source drivers and in some cases, that causes problems in your Ubuntu install. You might face some issues with the wireless or the graphics card. The good thing is that Ubuntu is aware of these issues and this is why it provides an easy way to install additional proprietary drivers.
You may use these additional drivers to get better performance on your system. If you find them not working, you can revert easily. From here, you can install drivers which are not installed by default during installation.
Go to the menu by pressing the Windows key. Here you will be able to see all the devices you can install drivers for. As shown in the image below, in case of other drivers like wireless drivers, you will get the option to either use the driver or to not use the device at all. After the installation is complete, you will get a restart option.
Click on it to restart your system and finish driver installation. The driver will be in use after the reboot. You can use lspci Linux command to check which graphics card do you have in your system.
The question is, why would you do that in the first place? In a few cases, the system would not boot at all and gets stuck at journalctl. If you are facing the boot problem because of Nvidia drivers, you can expand the next section to fix that problem.
You can do this using modprobe. You can use the arrow keys to move the cursor. After this, press F10 to boot and follow the rest of the simple steps. If your system still fails to boot most probably systems with series or series GPUsyou may need to add some more kernel parameters. Check this link for more information. In the previous section, you have already learned how to see the additional drivers available for your system. The open-source one and the proprietary one.
After installation is complete, you will get a restart button. Click on it to restart your PC and finish driver installation. I hope this quick tutorial helped you with Nvidia drivers and additional drivers in Ubuntu. If you have questions or suggestions, please let us know.
