 Posted: Fri Sep 06, 2024 7:39 pm Post subject: [SOLVED] no keyboard input in X with kbd driver |
 |
|
going for static /dev, so no udev/mdev and no libudev.
i configure X to use kbd and mouse drivers for input devices in xorg.conf.d, but...
mouse works, i expect it to!
keyboard doesnt work in X. 
just interacts with tty, so i can ctrl+c out of X, but i cant type anything
mouse also moves very fast and just feels "grid-aligned". maybe configuration could fix that but i just want to have keyboard input for now
any help?
keyboard config:
| Code: | ~ cat /etc/X11/xorg.conf.d/03-keyboard.conf
Section "InputDevice"
Identifier "system-keyboard"
Driver "kbd"
EndSection
|
(edit: solved, issue with my /dev, missing /dev/tty0  )

But the files you posted specify evdev as input driver...

changed the post so it should hopefully have the correct keyboard configuration,
sorry!! |

And did it work? You might have to restart the X server.
Be aware that not many people here have a static /dev setup, so available help might be quite limited....

well that configuration doesnt work, sadly. i have played with adding options to specify device and doing it with InputClass match stuff and so on and nothing changed with that
and im fine with whatever help i can get, i dont mind waiting for help.  |

Let's start by posting Xorg's log, then. It's usually /var/log/Xorg.0.log if the server is run as root. You'll have to retrieve it using a virtual terminal if the keyboard doesn't work with X.

It is. Well, it looks like the driver that you want to use for the keyboard is now used:
| Code: | [ 7892.055] Markers: (--) probed, (**) from config file, (==) default setting,
(++) from command line, (!!) notice, (II) informational,
(WW) warning, (EE) error, (NI) not implemented, (??) unknown.
...
[ 7892.058] (**) |-->Input Device "Keyboard0"
...
[ 7892.061] (II) LoadModule: "kbd"
[ 7892.061] (II) Loading /usr/lib64/xorg/modules/input/kbd_drv.so
...
[ 7893.145] (II) Using input driver 'kbd' for 'Keyboard0' |
But there is an error later which may or may not be related to your problem:
| Code: | | [ 7893.145] (EE) kbd: Keyboard0: failed to set us as foreground pgrp (Bad file descriptor) |
This error comes from the kbd driver, so we are entering "limited help available" territory  How are you starting the X server?

It looks like that is a failed call to tcsetpgrp(). You said in the OP that some things work with the keyboard, are you able to switch to a virtual terminal while X is running? If yes, could you post the line that corresponds to the X server in the output of ps -eo pid,pgid,sid,tname,args?

Does the expected X client (a window manager, I assume) start?

Hmm, it is strange that Xorg is using /dev/tty1, that's likely the virtual terminal that your shell is using, right? I believe that Xorg (if running as root) should be taking a free one. I also don't see in your log the "using VT number NN" message that is usually printed. What's the output of emerge --pretend --verbose x11-base/xorg-server? I want to see how it was installed.

yuviazzz,
xf86-input-evdev vs xf86-input-keyboard.
| hiZgb wrote: | [ 7892.053]
X.Org X Server 1.21.1.13
X Protocol Version 11, Revision 0
[ 7892.054] Current Operating System: Linux ivy 6.10.7-gentoo #2 SMP
... |
You are using latest Gentoo xorg-server:0/21.1.13 yet your kbd driver is from x11-drivers/xf86-input-keyboard-1.9.0
but x11-drivers/xf86-input-keyboard-1.9.0 is no longer in Gentoo portage tree and from xorg-server:0/21.1.13 point
of view, the xf86-input-keyboard-1.9.0 is not supported for Linux, instead x86-input-evdev should be use.
Not sure how you got xf86-input-keyboard-1.9.0 on your system but according to the source code you may have to define "Device" in
the configuration file for the keyboard. I don't know this will work or not but should take you to next code path.
Actually come to think of it, since X actually did started. so above may not be the reason you are not able to use keyboard. above will just silent the "Keyboard0: failed to set us as foreground pgrp (Bad file descriptor)" error message.
I think you should switch use xf86-input-evdev. |

yuviazzz is using a static /dev setup, so x11-drivers/xf86-input-keyboard is the only option here. And only the last version that still had the code for Linux.

I am not sure, but I think /dev/input/* is not relate to udev (not /dev/input/{by-id,by-path}, they are udev related). If no devtmpfs using. it is still possible use /sys/class/input/* to figure out major/minor number. So I think it is still possible.
if the startx was run by root, I think the "Device=/dev/tty1" worth a try. The code logic will at least open the tty. It is coded poorly, because it will always return TRUE no matter if keyboard can be opened or not. |

evdev_drv.so links to libudev.

If "Device" is not specified in the InputDevice section of the configuration file, as far as I understand, the kbd driver uses the terminal that Xorg grabbed:
src/lnx_kbd.c
| Code: | static Bool
OpenKeyboard(InputInfoPtr pInfo)
{
// ...
s = xf86SetStrOption(pInfo->options, "Device", NULL);
if (s == NULL) {
int rc;
pInfo->fd = xf86Info.consoleFd;
pKbd->isConsole = TRUE;
// ...
} else {
pInfo->fd = open(s, O_RDONLY | O_NONBLOCK | O_EXCL);
if (pInfo->fd == -1) {
xf86Msg(X_ERROR, "%s: cannot open \"%s\"\n", pInfo->name, s);
free(s);
return FALSE;
}
pKbd->isConsole = FALSE;
free(s);
}
return TRUE;
} |
One could specify a "Device", but I don't think it should be the same terminal as the shell's, and I don't know the consequences of pKbd->isConsole == FALSE in the rest of the code, so first I would try specifiying the virtual terminal as Xorg's argument.
yuviazzz, as a test, you could create this file in your home directory:
.xserverrc
| Code: | #!/bin/sh
exec /usr/bin/X -nolisten tcp "$@" vtn |
with "n" replaced by the number of a /dev/ttyn special file that you are certain that is not in use by an agetty process, and then try startx as usual.

sadly, X still stays in the virtual terminal my shell started in.
i tried tty7, tty8 and tty9, no difference.
would a display manager do anything here? |

Really? Does the output of ps -eo pid,pgid,sid,tname,args show the vt argument getting passed to Xorg? If yes, does the output still show Xorg grabbing /dev/tty1?
| yuviazzz wrote: | | would a display manager do anything here? |
It might invoke Xorg with different arguments, and might or might not make a difference. That is, if you find one that doesn't need libudev, and doesn't have a dependency that does...

evdev_drv.so links to libudev. |
My apology Flipping between tabs somehow I concluded xf86-input-eudev have no dependency on udev.
I think GDH-gentoo and I have same assumption that /dev/ have correct content. Since you manually create them can you share the information for them? | Code: | | ls -l /dev/tty[0-9] /dev/vc/* |
Modern linux seems don't have /dev/vc/* so missing that is ok.
And also So I know which linux source to check.
So using "kbd" driver. on tty1 run | Code: | | startx -- /usr/bin/Xorg :0 vt1 -logverbose 7 |
. After this command please share the Xorg's log. I am expecting to see some console/tty opening statement in the log.
You need to use "vt1" (aka tty1) because you start Xorg on tty1 and tty1 is the control terminal where input/output are focus on. So I am expecting the log should something about successful opening it. |

yuviazzz,
Thanks for the posting those information I requested.
unfortunately, none of indication messages show up in the version that with "vt1". I am not able to come up the reason why they not in the log. But just a guess/question. Did those two run have different output on the starting up terminal ?
Another question, After run "startx ..." did you got switch to X? or nothing happen, you session stay in terminal where you run the command? If it did switched, can you use <Ctrl><Alt><Fn> to switch back/forth? |

they had the same output.

it switches to X, but i can not switch back and forth
it is like both X and the virtual terminal are focused |
