That's the last piece for my Pentium 166 mosaic.
I've put the following snippet in xorg.conf.d but unsuccessfully:
Section "InputClass"
Identifier "Mouse0"
MatchIsPointer "On"
MatchDevicePath "/dev/ttyS0"
MatchDriver "mouse"
Option "EmulateWheel" "On"
Option "EmulateWheelButton" "2"
EndSection
Trying to use xorg.conf in the traditional way instead, the following snippet disables the keyboard as well:
Section "ServerFlags"
Option "AutoAddDevices" "False"
EndSection
Anything I can do?
-
You could try starting the gui without any xorg conf or snippets and then examine the xorg log to see what is detected and if any errors are found.
-
The attached one is the Xorg.0.log without any config file.
It seems there is no track of pointers.
-
I'm not sure if libinput and/or xf86-input-libinput can handle a serial mouse?
You might need to go back to xf86-input-evdev, but I would check the libinput documentation first.
-
It seems not to be any track of serial devices on the Libinput documentation.
I've found somewhere references to evdev + input-attach or xf86-input-mouse (not xf86-input-VMmouse, I guess). Are there packages available on TCL?

Hi t18
Try adding the boot code:
i8042.nopnpReboot and see if anything changed.
-
You would need to build xf86-input-evdev, see http://www.tinycorelinux.net/7.x/x86/tcz/src/xf86-input-evdev/ or xf86-input-mouse.
It might be easier to install tc-5.x and see if it’s going to work first.

Everything slower and no mouse detection.

I'll try 5.x as soon as I find another hard drive.

On x86_64 I'm using the last xf86-input-evdev.tcz extension (from TC13) instead of libinput with the current Xorg in TC15 and it works. I haven't tried a serial mouse though. I do know that Xvesa works with serial mice.
-
Installed TCL 5.4 but evdev doesn't detect any pointer.
Installed also xf86-input-mouse without any changes. I haven't found any reference on how configuring it (if necessary). The posts available on the web are generally outdated and it's difficult to align them to a specific Xorg version.
Yes, Xvesa supports serial mice but the available screen resolutions are lower than on Xorg.
-
Do you need something like this:
Section "InputDevice"
Identifier "Mouse0"
Driver "mouse"
# Option "Protocol" "auto"
# Option "Device" "/dev/mouse"
# Option "ZAxisMapping" "4 5 6 7"
Option "Protocol" "Microsoft"
Option "Device" "/dev/ttyS0"
Option "Emulate3Buttons"
EndSection

I can't find the exact man pages for the Xorg version in TC15, but this is for Debian with Xorg 21.1.7 vs 21.1.9 in TC15:
xorg.conf(5) (https://manpages.debian.org/bookworm/xserver-xorg-core/xorg.conf.5.en.html)
mouse(4) (https://manpages.debian.org/bookworm/xserver-xorg-input-mouse/mousedrv.4.en.html)
evdev(4) (https://manpages.debian.org/bookworm/xserver-xorg-input-evdev/evdev.4.en.html)
libinput(4) (https://manpages.debian.org/bookworm/xserver-xorg-input-libinput/libinput.4.en.html)

It seems some pages are just missing.

EndSection
Putting it in a 01-mouse.conf file, either alone or along with the above posted InputClass, has no effect.
Also putting Xorg-7.7 after the xf86-input-mouse entry in onboot.lst has no effect.
Finally, I haven't found the manner to disable hotplugging without locking the whole system.
Attached is my Xorg.0.log.

Check which driver extensions are loaded using:
tce-status -i | grep xf86
I suggest you try with xf86-input-evdev loaded, but not xf86-input-libinput or xf86-input-mouse and see what happens.
(I assume 01-mouse.conf is placed in /usr/local/share/X11/xorg.conf.d)
Also, it would be good to check which input your mouse is using with this: dmesg | grep ttyS

xf86-input-mouse removed fron onboot.lst, xorg.0.log attached.
libXxf86dga
libXxf86vm
xf86-input-evdev
xf86-video-fbdev
xf86-video-vesa

Yes, it is.
Also, it would be good to check which input your mouse is using with this: dmesg | grep ttyS
Mouse plugged in to COM1.
00:0c: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
00:0d: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A
-
So your keyboard is ttyS0?
Sorry, but I've run out of ideas - I don't have the hardware to test.
-
AFAIK the serial port 1 is ttyS0 and the mouse is usually plugged in to it.
While the serial port 2 is ttyS1, used for modems or digitizer.
On my pc the keyboard is plugged in to the AT port.
Anyway thank you so much for the time you have devoted to me, I'll keep it like that.

I guess by disabling hotplugging you're trying to stop this in the Xorg log:
Hotplugging is on, devices using drivers 'kbd', 'mouse' or 'vmmouse' will be disabled.
The 'mouse' driver accesses the mouse directly from the serial devices like in Juanitos configuration, but it's being disabled.
The other drivers rely on the Linux kernel having detected/configured the serial mouse correctly as described here (https://www.kernel.org/doc/html/v6.6/input/input.html). But that page doesn't mention serial mice.
I wonder if the Linux kernel's serial mouse driver ("sermouse" - built into the kernel according to the "CONFIG_MOUSE_SERIAL=y" settings in the build configuration (http://tinycorelinux.net/15.x/x86/release/src/kernel/config-6.6.8-tinycore)) isn't working, so the only way is to force Xorg to access the serial port directly via its 'mouse' driver (maybe by not loading either xf86-input-libinput or xf86-input-evdev but just xf86-input-mouse)?
It sounds like if the sermouse driver is working you should have a /dev/input/mice device that can be used like a PS/2 mouse by X.
I gather you can also check the Linux serial mouse device by loading libinput.tcz and running:
sudo libinput list-devices
And see if it lists a /dev/input/event* device that matches your serial mouse.

@t18, if/when you have the opportunity it would be interesting to investigate @CNK hypotheses and see what your results are.
Happy Holidays and keep us posted. thanks.

Will do. I'll have to find some time.
Best wishes you all.

xf86-input-libinput is not available on TCL 5.4.

You could delete the symlink at "/usr/local/lib/xorg/modules/input/evdev_drv.so".

If you can't try TC15 again then I'm not sure what the options are for viewing mice in TC5. You could try testing the emulated PS/2 mouse device in Xorg or with GPM, as described in the Linux kernel mouse driver documentation link.

Hi t18
... xf86-input-evdev loads even though removed from onboot.lst ...
Remove xf86-input-evdev.tcz from your local copy of Xorg-7.7.tcz.dep.

That's what I've done.

Yes, I can use TCL 15 again. But the aim would be to find the correct settings on TCL 5.x and then put them on TCL 15.
That's what I've caught.
Hi t18

Remove xf86-input-evdev.tcz from your local copy of Xorg-7.7.tcz.dep.
For mouse settings I'm using TCL 5.x as Juanito suggested.
I'll check if it's possible to remove evdev from it.

Remove xf86-input-evdev.tcz from your local copy of Xorg-7.7.tcz.dep.
Removing it the keyboard gets disabled, so I can't switch to prompt and check the Xorg.0.log.
-
You might need to configure the kbd driver too, like Juanito's example for the mouse driver. But if the mouse didn't work, I'm not sure there's anything more to do in order to make Xorg use the direct mouse driver.
