[rcore] `IsKeyPressed()` not working for some keys on RPI (`PLATFORM DRM`) #3569

larry104 · 2023-11-23T00:10:20Z

Discussed in #3565

^{Originally posted by larry104 November 22, 2023}
I notices that the block of keys (insert, delete home, end, pup, pdown) are not working. IsKeyPressed is not getting any event for these keys (I tried different keyboards and started the application from ssh terminal vs native terminal no difference). All other keys are working fine. Does anyone have an idea what is going wrong ?

Just to summarize: keys insert delete, home, end, page up, page down are not implemented in on the RPi (PLATFORM DRM in rcore_drm.c:

@larry104 Took the time to review this and IsKeyPressed() and all those keys (KEY_INSERT, KEY_DELETE, KEY_HOME, KEY_END, KEY_PAGE_UP, KEY_PAGE_DOWN, full enum at L564-L679) are working correctly for me.

Code example

#include "raylib.h"

int main(void) {
    InitWindow(800, 450, "test");
    SetTargetFPS(60);
    while (!WindowShouldClose()) {
        
        if (IsKeyPressed(KEY_INSERT)) { TraceLog(LOG_INFO, "KEY_INSERT"); }
        if (IsKeyPressed(KEY_DELETE)) { TraceLog(LOG_INFO, "KEY_DELETE"); }
        if (IsKeyPressed(KEY_HOME)) { TraceLog(LOG_INFO, "KEY_HOME"); }
        if (IsKeyPressed(KEY_END)) { TraceLog(LOG_INFO, "KEY_END"); }
        if (IsKeyPressed(KEY_PAGE_UP)) { TraceLog(LOG_INFO, "KEY_PAGE_UP"); }
        if (IsKeyPressed(KEY_PAGE_DOWN)) { TraceLog(LOG_INFO, "KEY_PAGE_DOWN"); }

        BeginDrawing();
        ClearBackground(RAYWHITE);
        EndDrawing();
    }
    CloseWindow();
    return 0;
}

It doesn't work with raylib 4.5 ... is that something which might have been fixed in 5.x ?.

I tired from ssh shell as well as native shell. (bullseye, raspberry pi zero

@larry104 4.5 is around 8 months old now. Since then, a substancial amount of changes and fixes were issued to PLATFORM_DRM. Please test it with the 5.0 release or the current master branch.

raysan5 · 2023-11-27T17:31:09Z

I'm closing this issue, it seems it refers to an old raylib version.

larry104 · 2023-11-27T17:31:17Z

I compiled the test case using the master branch 5.1.-dev and it still does not work for those keys. I added a log for the BACKSPACE key and that works fine:

@larry104 I can't reproduce the issue. Tested it again right now and it's working correctly for me:

larry104 · 2023-11-27T17:54:07Z

This is super strange. I tested it on a RPi3 and RPi Zero and both don't work ... What locale do you have set on your RPi? I have no other idea why this does not work for these 6 keys

larry104 · 2023-11-27T17:58:15Z

Keyboard is set correctly ...
cat /etc/default/keyboard
XKBMODEL="pc105"
XKBLAYOUT="us"
XKBVARIANT=""
XKBOPTIONS=""
BACKSPACE="guess"

ghost · 2023-11-27T18:06:50Z

@larry104 I'm using en (english), US (United States), UTF-8, everything stock from the Raspberry OS image. However, I'm accessing it directly.

If you're accessing it through SSH, then the keyboard handling is done by exclusively by ProcessKeyboard() (L1304), that's the part you mentioned previously (#3569 (comment)). And there, just for SSH, it's missing quite a lot of keys (specially the key cluster from the issue).

To have those on SSH you'd have to add them probably around at L1389-L1390 with another else if. But note that there's a lot more keys missing from the full enum (L564-L679), so it would be just a partial fix.

Side-note: I'm really not sure if the SSH input was ever meant to be actually fully supported, or just some shortcut for basic testing. @raysan5

larry104 · 2023-11-27T18:18:05Z

I connected a keyboard to the RPi, rebooted and tested again ... still same issue. Is there any compile flag needed other than
set(PLATFORM DRM)?

ghost · 2023-11-27T18:25:34Z

@larry104 My exact steps here:

Downloaded current master branch (811abcb) from the git repository, then:

~$ unzip raylib-master.zip
[...]
~$ cd raylib-master/src/
~$ make PLATFORM=PLATFORM_DRM
[...]

Replaced the content of raylib-master/examples/core/core_basic_window.c with:

#include "raylib.h"

int main(void) {
    InitWindow(800, 450, "test");
    SetTargetFPS(60);
    while (!WindowShouldClose()) {
        
        if (IsKeyPressed(KEY_INSERT)) { TraceLog(LOG_INFO, "KEY_INSERT"); }
        if (IsKeyPressed(KEY_DELETE)) { TraceLog(LOG_INFO, "KEY_DELETE"); }
        if (IsKeyPressed(KEY_HOME)) { TraceLog(LOG_INFO, "KEY_HOME"); }
        if (IsKeyPressed(KEY_END)) { TraceLog(LOG_INFO, "KEY_END"); }
        if (IsKeyPressed(KEY_PAGE_UP)) { TraceLog(LOG_INFO, "KEY_PAGE_UP"); }
        if (IsKeyPressed(KEY_PAGE_DOWN)) { TraceLog(LOG_INFO, "KEY_PAGE_DOWN"); }

        BeginDrawing();
        ClearBackground(RAYWHITE);
        EndDrawing();
    }
    CloseWindow();
    return 0;
}

Then compiled and tested it with:

~$ cd ../examples/
~$ make PLATFORM=PLATFORM_DRM core/core_basic_window
[...]
~$ cd core/
~$ ./core_basic_window
[...]

Edit: formatting.

larry104 · 2023-11-27T18:45:24Z

I am fetching it with cmake but just to make sure ... I did exactly what you did and it does not work. I even tried on bookworm . hmm

ghost · 2023-11-27T18:57:07Z

@larry104 I really don't know what could be causing that issue. Perhaps try another keyboard just to be sure?

larry104 · 2023-11-27T19:07:27Z

I just tried a different keyboard ... same exact issue ... and I added a control key BACKSPACE which works
the INFO message shows also correctly

The logs are pretty much identical ... I even changed XKBVARIANT="intl" since it wasn't set but there is no difference. Can you point me to the code where the key events are captured. I can add some debug prints in there to see what's going on.

ghost · 2023-11-27T19:55:35Z

@larry104 Sure thing. The keyboard polling for PLATFORM_DRM direct input happens on PollKeyboardEvents() (L1682) which is called by PollInputEvents() (L563).

Wild guess: try changing 255 to 512 or to MAX_KEYBOARD_KEYS at L1701.

Edit: editing.

raysan5 · 2023-11-27T20:14:12Z

@larry104 are you running PLATFORM_DRM in native mode, right? I mean, without any windowing system/desktop.

larry104 · 2023-11-27T20:34:34Z

yes, I do. it says INFO: Platform backend: NATIVE DRM ... I boot directly into a terminal.

It seems the code never enters the while loop in line

raylib/src/platforms/rcore_drm.c

Line 1691 in 811abcb

while (read(fd, &event, sizeof(event)) == (int)sizeof(event))

Meaning no log messages inside the while loop but directly before the while there are log messages getting printed

@larry104 Sorry, not sure I understand. I was able to log inside it:

larry104 · 2023-11-27T21:00:26Z

In my caser there are no prints happening ... platform.keyboardFd is 8. read() returns always -1

ghost · 2023-11-27T21:09:26Z

@larry104 Did exactly like your print and was able to print it:

raysan5 · 2023-11-27T21:17:12Z

Side-note: I'm really not sure if the SSH input was ever meant to be actually fully supported, or just some shortcut for basic testing.

@ubkp I created it for my convenience when I implemented RPI support first time, definitely not a priority and probably useless at this point.

@larry104 Could you verify if PollKeyboardEvents() is actually called? I'm afraid some printf-debugging is required on your side...

larry104 · 2023-11-27T22:08:17Z

Yes, PollKeyboardEvents() is called but

raylib/src/platforms/rcore_drm.c

Line 1691 in 811abcb

while (read(fd, &event, sizeof(event)) == (int)sizeof(event))

returns always -1 so it never enters the while loop

raysan5 · 2023-11-27T22:40:28Z

@larry104 could it be related to some kind of security reason? did you try running the example as root?

larry104 · 2023-11-27T22:46:16Z

I tried as root no difference ... what I don't understand why other keys work just these 6 not ... that is all really strange

larry104 · 2023-11-28T18:06:40Z

ok you won't believe it but I installed a brand new OS (based on bullseye) exactly the one you had with desktop environment. Changed it to boot into CLI, updated packages and installed the list of packages needed to compile raylib. Compiled the example we had before. BUT, it still does not work. Now I am really puzzled ... I should mention I didn't uncomment the SUPPORT_SSH_KEYBOARD_RPI ... do you want me to try that too?

ghost · 2023-11-28T18:36:01Z

I should mention I didn't uncomment the SUPPORT_SSH_KEYBOARD_RPI ... do you want me to try that too?

@larry104 No need. It really should have worked like that.

I'm afraid that only leaves hardware as the possible issue. Are you using some KVM switch? Or an USB hub? Or a mechanical keyboard? Or a wireless/bluetooth keyboard?

Edit: typo.

larry104 · 2023-11-28T19:03:15Z

Since I did this test on a RPi Zero I used a USB hub. But, I tried it without the hub as well. I also tried swapping this standard Microsoft keyboard with a Bluetooth keyboard. Same issue. I can try to get some other keyboards as well but I'm not confident it solves the problem. It's a mystery ...

ghost · 2023-11-28T19:06:40Z

@larry104 Yeah, probably not hardware then.

Do you have SSH enabled? If yes, could you disable it, then try to recompile raylib and the example with SUPPORT_SSH_KEYBOARD_RPI disabled?

Edit: while recompiling raylib, could you please post the output so I can see the errors/warnings?

raysan5 · 2023-11-28T19:56:14Z

this is a really strange issue...

larry104 · 2023-11-28T22:40:29Z

I recompiled with SUPPORT_SSH_KEYBOARD_RPI disabled. There were no errors/warning during the compile. Now we are back to that no key at all works. What is super strange is I gave the code to a friend with a RPi 3 and he tested it but it was still based on the 4.5 version I was compiling against and he was having the same problems. That at least makes me believe it's not a HW problem.

ghost · 2023-11-28T22:48:23Z

@larry104 I'm going to reflash my Raspberry Pi right now. I'll use this exact image: 2023-05-03-raspios-bullseye-armhf.img.xz. I'll report back in a few minutes.

ghost · 2023-11-29T00:30:48Z

@larry104 This was exactly what I did (with as much detail as possible):

Model: Raspberry Pi 3 Model B 1.2 (Raspberry Pi 2015)

MicroSD: Sandisk Ultra 16GB Class-10 MicroSD HC I

Keyboard: Corsair Strafe RGB Cherry Mx Silent

OS: Raspberry Pi OS (Legacy) with desktop
Release date: May 3rd 2023
System: 32-bit
Kernel version: 6.1
Debian version: 11 (bullseye)

On my host PC (Linux Mint 21.1 64-bit), downloaded the Raspberry Pi OS image from https://www.raspberrypi.com/software/operating-systems/#raspberry-pi-os-legacy to my home folder, then did this:

~$ ls *.img.xz
2023-05-03-raspios-bullseye-armhf.img.x

~$ unxz 2023-05-03-raspios-bullseye-armhf.img.xz

Moved the MicroSD from my host PC to the Raspberry Pi.
Powered the Raspberry Pi.
On its first boot it automatically resized.
It also automatically generated SSH keys.
Then it automatically rebooted.
On the welcome screen I clicked Next.
On the next screen I selected Country, Language, Timezone, [x] Use english language, [x] use US keyboard, then clicked Next.
On the next screen I filled user as username, then a password, then confirmed the password, then clicked Next.
On the next screen I kept reduce the size of the desktop as off/disabled, then clicked Next.
On the next screen I selected/connected to my wifi, then clicked Next.
On the next screen that was about update software I clicked Skip.
On the next screen that was setup complete, I clicked Restart.
Then it rebooted.
After the reboot, I opened the installed Chromium Web Browser.
Opened https://github.com/raysan5/raylib
Downloaded the current master branch zip.
Opened a terminal and did the following:

Then I repeated everything (reflashed the Raspberry Pi and all that) with another keyboard: CMStorm Quickfire Stealth Cherry Mx Brown.
Everything worked perfectly for me both times. I have absolutely no idea what could be going wrong there.

larry104 · 2023-11-29T00:46:08Z

Here might be the difference, can you try booting directly into CLI instead compiling it from X11?

ghost · 2023-11-29T01:02:01Z

@larry104 Tested right now. It's also working correctly for me:

larry104 · 2023-11-29T01:20:32Z

wow, now I am literally going insane. I have no more ideas ... If you use the RPi Imager on Windows you can set locale, ssh, wifi etc. before you actually flash the image and this is what I did. Let me do it all over again and do it later from X11 .. I try one more time and then I buy a new RPi ;-)

ghost · 2023-11-29T01:23:15Z

If you use the RPi Imager on Windows you can set locale, ssh, wifi etc. before you actually flash the image and this is what I did.

@larry104 Maybe that's the problem. Can you flash it some other way?

larry104 · 2023-11-29T01:29:00Z

I still used the Imager but didn't make any changes to settings ... flashing just done ...

ghost · 2023-11-29T01:55:52Z

@larry104 Meanwhile I reflashed my Raspberry Pi with https://www.raspberrypi.com/software/operating-systems/#raspberry-pi-os-32-bit

OS: Raspberry Pi OS Lite
Release date: October 10th 2023
System: 32-bit
Kernel version: 6.1
Debian version: 12 (bookworm)
Size: 568MB
Show SHA256 file integrity hash: 1f8a646b375b198ef9f48c940889ac9f61744d1c1105b36c578313edbc81a339

No X11 or anything, just CLI.

Did the standard first boot and CLI basic setup.
Connected to the wifi via raspi-conf.
Then the usual sudo apt-get update.
Then sudo apt-get install libdrm-dev libegl1-mesa-dev libgles2-mesa-dev libgbm-dev
Copied the raylib-master.zip and the test.c with a pendrive to the Raspberry Pi.
Unzip the raylib-master.zip. Copied the test.c to examples/core/core_basic_window.c.
Then make PLATFORM=PLATFORM_DRM.
Then cd ../examples/ and make PLATFORM=PLAFTORM_DRM core/core_basic_window
And it still worked for me:

larry104 · 2023-11-29T02:04:56Z

ok ... that would really point to a HW issue. Let me finish that current setup and I try to find another keyboard, I think I have one more somewhere. If that doesn't work I order the latest RPi Zero 2 W.

ghost · 2023-11-29T02:12:44Z

@larry104 I was able to replicate the issue!

Found a keyboard here that doesn't work (a Microsoft Confort Curve Keyboard 3000).

Edit:
My Corsair Strafe RGB Cherry Mx Silent works.
My CMStorm Quickfire Stealth Cherry Mx Brown works.
My Logitech K310 works.
My Dell SK-8115 works.
But the Microsoft Confort Curve Keyboard 3000 doesn't work. Same issue you're having.
Ok, now I have something to work with.

larry104 · 2023-11-29T02:24:55Z

oh wow ... this is awsome ... so I am not insane after all!!!!! Mine is a Microsoft Wired Keyboard 600 and the other one a Microsoft Wireless Desktop 900 Keyboard. I will ask my friend what he was using.

ghost · 2023-11-29T02:58:06Z

@larry104 It's honestly amazing how MS can't even make keyboards right. Why I am not surprised...

Either way, the problem appears to be that this (these) keyboard(s) are registering twice on the /proc/bus/input/devices

Once you unbind the duplicated:

Then everything works as expected:

So, definitely not a raylib issue. :)

Edit: typo.

larry104 · 2023-11-29T05:01:50Z

I was about to say the same thing about MS ;-) Too bad I had two of them to test. Thank you so much for all your help to figure it out!!!! And people will find here now the best installation instructions of raylib on a RPi with bullseye or bookworm ;-)

ghost · 2023-11-29T12:50:53Z

@larry104 No problem. 👍

Haha, for sure. :)

raysan5 · 2023-11-29T18:25:16Z

@larry104 @ubkp Wow! Amazing research work! Congratulations! Really impressed you found the root of the issue!

@michaelfiber Were you aware of this issue with those Microsoft keyboards?

Is there any possible work-around for this issue? How do other libraries address it (SDL)?

michaelfiber · 2023-11-29T18:56:50Z

@michaelfiber Were you aware of this issue with those Microsoft keyboards?

If I'm reading the thread right, I've encountered this. My microsoft keyboard shows up as 2 keyboards. My keychron shows up as 3 keyboards and 2 mice. And the built in keyboard of my dell rugged laptop shows up as 2 keyboards and 1 mouse even though it has a touchscreen AND a touchpad.

I think it's actually quite common with any keyboards that have any kind of nonstandard keys on them. I believe my old SteelSeries did too as well as some of my other keyboards.

But the input code I've been using doesn't have an issue with it because I poll all keyboard devices and combine their input into a single logical keyboard. But when I get back to working on the input stuff I'll be sure to see if my approach works here. It is possible I didn't test those keys because I don't press them a ton.

@michaelfiber Oh! That sounds like a good approach. Please, let us know if you test it.... and feel free to open a PR for the inputs update when possible... ;)

larry104 · 2023-11-29T19:04:01Z

btw/ I confirmed on my side I get the MS keyboard twice in /proc/bus/input/devices and I confirmed that my friend also had a MS keyboard. How are the odds having 3 MS keyboards ;-). I further confirm that my Logitech MS keyboard works without any problems. The Logitech keyboard appears only once in /proc/bus/input/devices

ghost · 2023-11-29T20:20:58Z

I think it's actually quite common with any keyboards that have any kind of nonstandard keys on them.

That's true. I've tested a few more keyboards and, indeed, many appear as more than one device and still work properly.

So I guess the actual problem is probably related to that specific MS keyboard device-family. My best guess is either the device-family common firmware or somewhere between that and evdev.

But the input code I've been using doesn't have an issue with it because I poll all keyboard devices and combine their input into a single logical keyboard.

That would be an excellent solution.

larry104 · 2023-11-29T22:37:48Z

@ubkp I found another issue with the keyboard. When using the keyboard through ssh the key repeat works without any problems. When using a keyboard connected directly to the RPi the key repeat does not work.

ghost · 2023-11-29T23:41:30Z

@ubkp I found another issue with the keyboard. When using the keyboard through ssh the key repeat works without any problems. When using a keyboard connected directly to the RPi the key repeat does not work.

@larry104 Nice catch! I'll send a PR fixing it shortly. 👍

jamesl-github · 2023-11-30T00:56:18Z

this seems like a different issue with the 3000, but could it be related ?

[quote]
Windows 10 forces my Microsoft Comfort Curve 3000 keyboard to sleep after 5 seconds of inactivity, and it thinks keeping a key pressed down is inactivity. If it sleeps the keyboard with key down, the key is stuck, it doesn't register the key-up event, unless you press and release it again.

The fix is to go to Control Panel with Win-X menu, select Hardware and Sound, select Devices and Printers, right click on your keyboard, select Properties, click on Hardware, click on USB Input Device and then Properties, then Change settings, then Power Management and remove check mark from "Allow the computer to turn off this device to save power".

ghost · 2023-11-30T01:57:47Z

@jamesl-github It's hard to tell. At first glance I don't think it's directly related. That looks like a driver issue and/or driver management issue by the Windows OS.
