I have a Lenovo Ideapad 320-15ABR, (I found the exact model name with dmidecode). I'm having trouble getting the touchpad to work. It's not showing up in xinput --list or cat /proc/bus/input/devices. I'm using Linux 4.13.2, compiled with some extra debugging messages. Here's some relevant dmesg output when booted with i8042.nopnp.

I am working on an embedded Linux (kernel 5.10.24) with a touch screen. Now I want to trigger touch event by writing to /dev/input/eventX corresponding to the touch screen. To figure out the event I want to emulate, I firstly collected the events by touching the screen. Then I hard coded the events in codes and write them one by one to the /dev/input/eventX. Below are the events I got from a touching.

~ # ./touchevent
timeS=1651152027,timeUS=312095,type=3,code=57,value=50
timeS=1651152027,timeUS=312095,type=3,code=53,value=218

timeS=1651152027,timeUS=312095,type=0,code=0,value=0
timeS=1651152027,timeUS=448388,type=3,code=57,value=-1
timeS=1651152027,timeUS=448388,type=1,code=330,value=0
timeS=1651152027,timeUS=448388,type=0,code=0,value=0

I hardcoded the first 7 events (including an EV_SYN) to write to /dev/input/eventX.

#include 
#include 
#include

#include 
int main( void )
{
        int                     fd;
        int                     ret;
        struct input_event      event;

        fd = open( "/dev/input/event0", O_RDWR);
        if ( fd < 0 )
        {
                perror( "/dev/input/event0" );
                return(-1);
        }

        event.type = 3;
        event.code = 53;
        event.value = 218;
        ret     = write( fd, &event, sizeof(struct input_event) );
        printf("ret: %d\n", ret);

        event.type = 3;
        event.code = 54;
        event.value = 1223;
        ret     = write( fd, &event, sizeof(struct input_event) );
        printf("ret: %d\n", ret);

        event.type = 3;
        event.code = 48;
        event.value = 54;
        ret     = write( fd, &event, sizeof(struct input_event) );
        printf("ret: %d\n", ret);

        event.type = 3;
        event.code = 58;
        event.value = 54;
        ret     = write( fd, &event, sizeof(struct input_event) );
        printf("ret: %d\n", ret);

        event.type = 1;
        event.code = 330;
        event.value = 1;
        ret     = write( fd, &event, sizeof(struct input_event) );
        printf("ret: %d\n", ret);

        event.type = 0;
        event.code = 0;
        event.value = 0;
        ret     = write( fd, &event, sizeof(struct input_event) );
        printf("ret: %d\n", ret);

        close( fd );
.....
}

When I ran the code on the target, there is NO expected response from the touch screen. I am not sure if it is possible to emulate touch events by writing to /dev/input/eventX, if so, what did I miss on doing it ? I don't have sendevent/getevent tools from Andriod, and I want to do this by myself.

Is it possible to make a window believe that it has a focus while it has not? My use case description: I am playing a game named Detroit Become Human. I am playing with gamepad. The game is actually an interactive movie. It has a very complicated flowcharts. I want to see other scenes that I missed after my original walkthrough. I am reading the walkthrough guide in a browser and switching to game very often and want to see flowchart in a game. Because the flowcharts are very complicated, I need to keep lots of tabs in browser, constantly scroll pages up and down trying to read descriptions for some nodes. And I get really annoyed that I constantly need to refocus a game itself to be able to control it (even with gamepad) and press alt+tab to release mouse from the game. Also, the game makes me rewatching lots of scenes that I already have seen and I want to do some other readings while such scenes are playing. Also, there are scenes with minor interactions, but still I need to focus a game window for them. I wanted to make it easier. I want the game to be controllable by gamepad while its window not in focus. I thought that I need to capture a gamepad input and redirect it to inactive window. And that thing was what I wanted originally to ask. However, I have noticed, that chromium while not in focus is still able to see the gamepad input by using this web site: https://gamepad-tester.com/ . This means (as I think) that all windows have access to the gamepad input. Now I think that the problem is the game itself. I think it checks if it is in focus, and if not, it do not interprets the input. I want the game to always interpret gamepad, even when missing focus. Is that possible? My system details: Arch Linux. Game launched via steam. Tried with Steam Input and without it. KDE Plasma. Logitech F710 Gamepad in XInput mode. The game launched in borderless window mode, also tried fullscreen and windowed. Additional info. This trick may be useful not only for games (which often pauses when not in focus), but also for applications. For example, DaVinci Resolve hides a window with effects parameters. I am watching a tutorial video on youtube in browser. When I focus a browser, I cannot see my parameters window to compare it with such on a youtube. Tricking the DaVinci Resolve that it has focus (while still disabling keyboard input for it) may solve this.

bit of a strange issue for you. I have an old 2-in-1 laptop tablet thing that works well enough, except the driver for the touchscreen occasionally crashes, leaving it unusable. I have a simple script to restart it, but when it's not connected to the keyboard this can be a pain. My proposed solution is to run the script when I press both physical volume keys simultaneously (these buttons being the only other input device that I will reliably have connected). I am on Fedora Wayland. Does this seem feasible, and if so, how might it be done?

on antiX I need a on screen keyboard, I went with "onboard" and installed it. I also have multiple input languages set up in the antiX control center (German, Russian). Onboard seems to recognize it, because it shows me the layout of the correct language but as soon as I klick on a button it switches back to English and the character it puts in is actually also from the English layout. What can I do?

Everything on my system (that needs it) supports UTF-8 just fine.
That's all nice when you want output... But what if you want easy **in**put ? At the moment the only non-ASCII chars I can easily type are chars like é by using AtlGr.
But for chars like ₂ ² ≈ √ π 😀 at the moment I have to: 1. Open a browser 2. Surf to https://www.utf8icons.com or a similar site 3. Click, type and search a lot on the site to get to a page that contains the symbol i want 4. Copy it 5. Paste it in the program where I need it 6. (Optionally) close the browser What I'm looking for is a program that can do something like this: - Run in the background in a modern desktop environment (in my case Cinnamon) - Jump to the foreground to show a whole list of reasonably popular UTF-8 symbols after pressing something like F1 - Let me click a symbol after which it will be sent to the program I was last using as if it was a keypress - Give me the option to configure it to either stay visible after this "fake keypress" or jump back to background In short: Are there virtual keyboard programs with support for non-ASCII UTF-8 ? Actually... I am already happy with *any* method that improves mine. **Edit:** *For others ending up here and don't want to read all the answers themselves (or add a answer that's already given):
These are the options already mentioned + links to the answers + pro's and contra's.
Feel free to add extra solutions below (after providing them as detailed answer)*: - ibus (usually with CtrlShiftE) → Can't get it to work on Cinnamon - onboard → *pro*: Seems to do everything I need + has support for snippets, *con*: Only (by default) included non-latin layout is for math, other layouts with popular UTF-8 chars have to be created manually - gucharmap → *pro:* Lots of chars and easy to search *con:* Doesn't easily jump between foreground/background (can probably be handled with a workaround in Cinnamon itself) - kcharselect→ Same pro/con as gucharmap - Solutions from the programs themselves (e.g. Ctrl. for a couple of them) → *pro*: Ideal for that exact program *con*: Most programs, including the ones where it's needed the most, don't have one + it's not uniform - https://www.unicodeit.net/ → *pro*: Good for long math formula's. *con*: Same problem as the one I originally stated + useless for non-math symbols - Keyboard with extra symbols → *pro*: Easy *con*: Small amount of chars + extra keyboard needed for each system - Shortcuts for the most used chars with xcompose → *pro*: Easy *con*: Depending on your memory (as human, not as computer) it only works for a limited amount of chars - HTML entities to compose - *pro/con*: Too much of each, see answer - Use CtrlShiftU, Hexcode,Space : *pro/con*: Same as above

Sometimes I cat a stream like /dev/input/event0. I want to write a script that does something every time there is more output. The definition of more output might be every time it reads a byte. How can that be done? is there some command that does it?

For instance, if I want to run from a shell script something in python I would do: echo 'print("hello world")' | python2 Now imagine I want to run something interactive, i.e., it needs my input, for instance name = raw_input("Enter your name:") By doing: echo 'name = raw_input("Enter your name:")' | python2 I get an error. So how is the correct way to run something from bash but that I can interact with? PS - this is simply an example. I need to run a set of scripts in a different external program (not python), and some of these scripts need some input from the user. Everything runs smoothly until the point when there is the need for input, where the current script crashes and passes to the next. Thanks :)

I have a registered function in ZSH that searches file contents under the current path for a match and then captures the resulting filename. This is then bound to a key combination. The keybinding, search and result all work fine (as in they return the desired value). When I am using the keybinding, the value is printed out to the current shell line but it is not recognised as actual input (i.e. if I hit enter the value is considered empty and nothing is added to the prompt history). How do I output the result as if it were typed and a valid value. I have have attempted echo/print/printf (assuming the outcome would be the same for each) but also appending to BUFFER and setting CURSOR. I'm sure this is well documented and I'm failing to find examples because of the lack of correct terminology. Can anyone point me in the right direction?

If I create a mount namespace with unshare or a more sophisticated tool like Docker, can I emulate an input device using a userspace process on the host? I'm aware of /dev/uinput as a mechanism for emulating input devices, but it doesn't hew to any sort of namespacing (to my knowledge). Instead, I would like to mount a normal file inside the container, but somehow handle ioctls done on it, and in doing so act like evdev to simulate an input device. Is such a thing possible on Linux? Am I missing something in my understanding (ioctls are pretty mysterious to me)?

I'm using KDE desktop environment, and I have recently switched from Xorg to Wayland. The compositor is KWin.
I'm concerned about configuring my mouse and keyboard properly, because obviously it can't be now done with xorg.conf as it was before.
I wasn't able to find any documentation related to configuring KWin when using it w/o Xorg. There are advantages for me in using Wayland, but I'm really confused about it's design. I can't understand which programs now take care of my hardware, when there's no Xorg server. For example, the graphics backend: it uses DRM automatically, but where can it be configured?
As another example, this was my keyboard configuration, where I had keyboard layout set, and few other options:

Section "InputClass"
    Identifier     "Keyboard0"
    Driver         "evdev"
    Option         "Protocol" "auto"
    Option "XkbLayout" "us,tr"
    Option "XkbOptions" "grp:alt_shift_toggle,terminate:ctrl_alt_bksp"
    Option "GrabDevice" "false"
EndSection

Without Xorg, where do I configure my input drivers so the Wayland compositor will use the correct settings?
Another part of config which I also need, is related to blacklisting virtual mice from being added to the session (I use them for different purpose):

Section "InputClass"
    Identifier     "ignore virtual mouse"
    MatchProduct     "melon69-virtual-mouse"
    MatchIsPointer      "on"
    Option "Ignore" "on"
EndSection

Is it possible to configure a Wayland compositor for the same behavior (blacklisting input devices), or I have to go by removing user permissions on the device nodes?
Thanks for your help!

Is there a method with X11 to intercept(catch and prevent delivery) mouse input events targeting a given window, such that if the window is currently focused that it retains focus?

Something that has been annoying me for a bit is that my caps:escape xmodmap option does not work in some games including Minecraft and Team Fortress 2. When pressing the capslock/escape button, nothing happens; it triggers neither an escape key event nor letter capitalisation toggle. This is consistent across Xorg (i3) and Wayland/xwayland (Hyprland). I can't find a determining factor that is consistent across all scenarios because it does work in Cities:Skylines. Looking at libraries/APIs used, all games use OGL, C:S and TF2 use SDL2 and the bug is present in MC eventhough it uses the LWJGL/GLFW middleware and generally has very little in common with the other two games. What could be the cause and how can I make it use my xmodmap options? (I'm not interested in alternatives to using xmodmap, I'm aware you could achieve a capslock remap through different means.)

From all the .conf files used to configure XInput, it seems X11 innately does not support a Z axis, let alone relative rotations. Is this correct? How are trackballs supported, if at all? Are spacemice supported? If so, how? Does this carry over to Tk/Gtk/Qt hence target apps using those frameworks?

If I type xinput I get the following output:

⎡ Virtual core pointer                          id=2    [master pointer  (3)]

in other words, individual input devices have individual IDs & names. When receiving an input event, it is usually possible to differentiate whether it came from a mouse or a keyboard. But is it also possible to differentiate from *which* mouse or keyboard it came from? If possible in X11, does this carry over to Tk/Gtk/Qt?

I have a bash lopp as #!/bin/bash for (( c=0; c<=1000000; c++ )) do SOME STUFF HERE done I interrupt the long loop by a keyboard input like Ctrl+C but Ctrl+C simply terminates the script. I am looking for an alternative to continue the current cycle and break the loop after finishing the running STUFF in the current cycle.

I'm using Xorg with AutoAddDevices disabled, because I have many input devices on my server, which mustn't all be added to my physical session. The input devices I need are pre-configured in the xorg.conf.
Everything works great, until my input device disconnects (for example due to EMI). And after that happens, when it connects back, it is not being taken up automatically by X. The Xorg server becomes absolutely uncontrollable, and I can't even switch the VT. I have to log in via serial port or SSH, just to kill that Xorg server (together with all the programs which were running with it). After doing that, the screen returns to the TTY and the input starts to work. I start Xorg from scratch then.
Is there any solution to the problem, other than enabling AutoAddDevices?

I recently got a new laptop and installed Arch on it. I noticed that in a few applications, including chrome and gedit, pressing ctrl+shift+e will cause the next few keys pressed to be underlined, beep when pressed, and then deleted. I've looked around for a while, and the only way I can seem to "fix" it is to unload the pcspkr module. However, this still doesn't fix the issue, it only silences the beeping. It seems to happen under both gnome and i3, but not in a tty. Is there any way I can turn this off? Video of the behavior
