Dear Linux developers, First of all, thank you for the work you do with your contributions every day. Much appreciated. I have been having problems for some time to be able to use the trackpoint (the red button with mouse functions) that the keyboard of my Thinkpad T530 has. I have had this problem in Debian 11 with Linux 5.14 and now in Debian Testing with Linux 6.1. I think this setting should enable the Trackpoint: root@orion:~# cat /etc/modprobe.d/psmouse.conf options psmouse synaptics_intertouch=1 proto=any In fact, after this configuration I am able to see it with xinput: viper@orion:~$ xinput ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ USB OPTICAL MOUSE id=9 [slave pointer (2)] ⎜ ↳ TPPS/2 IBM TrackPoint id=12 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ Video Bus id=7 [slave keyboard (3)] ↳ Sleep Button id=8 [slave keyboard (3)] ↳ Integrated Camera: Integrated C id=10 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)] ↳ ThinkPad Extra Buttons id=13 [slave keyboard (3)] But it does not work. A look in syslog shows the following: root@orion:~# tail -F /var/log/syslog 2023-04-01T11:48:57.295761-03:00 orion kernel: [ 634.652388] psmouse serio1: Failed to enable mouse on isa0060/serio1 2023-04-01T11:48:57.959746-03:00 orion kernel: [ 635.316599] psmouse serio1: Failed to enable mouse on isa0060/serio1 2023-04-01T11:48:58.623769-03:00 orion kernel: [ 635.978783] psmouse serio1: Failed to enable mouse on isa0060/serio1 2023-04-01T11:48:59.287780-03:00 orion kernel: [ 636.642962] psmouse serio1: Failed to enable mouse on isa0060/serio1 2023-04-01T11:48:59.955781-03:00 orion kernel: [ 637.311116] psmouse serio1: Failed to enable mouse on isa0060/serio1 2023-04-01T11:49:00.619767-03:00 orion kernel: [ 637.975234] psmouse serio1: Failed to enable mouse on isa0060/serio1 2023-04-01T11:49:01.279768-03:00 orion kernel: [ 638.636391] psmouse serio1: Failed to enable mouse on isa0060/serio1 2023-04-01T11:49:01.951713-03:00 orion kernel: [ 639.306422] psmouse serio1: Failed to enable mouse on isa0060/serio1 2023-04-01T11:49:02.615760-03:00 orion kernel: [ 639.970611] psmouse serio1: Failed to enable mouse on isa0060/serio1 --------------- Using this setup I am able to enable the Trackpoint, although it is detected as a PS/2 mouse and it is extremely slow: root@orion:~# cat /etc/modprobe.d/psmouse.conf options psmouse synaptics_intertouch=1 proto=exps viper@orion:~$ xinput ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ USB OPTICAL MOUSE id=9 [slave pointer (2)] ⎜ ↳ PS/2 Generic Mouse id=12 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ Video Bus id=7 [slave keyboard (3)] ↳ Sleep Button id=8 [slave keyboard (3)] ↳ Integrated Camera: Integrated C id=10 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)] ↳ ThinkPad Extra Buttons id=13 [slave keyboard (3)] root@orion:~# tail -F /var/log/syslog 2023-04-01T11:50:59.559695-03:00 orion kernel: [ 756.915044] psmouse serio1: Failed to enable mouse on isa0060/serio1 2023-04-01T11:51:03.475677-03:00 orion kernel: [ 760.833751] input: PS/2 Generic Mouse as /devices/platform/i8042/serio1/input/input23 2023-04-01T11:51:06.334813-03:00 orion (udev-worker)[4466]: input23: /etc/udev/rules.d/10-trackpoint.rules:1 Failed to write ATTR{/sys/devices/platform/i8042/serio1/i> 2023-04-01T11:51:06.967054-03:00 orion kded5[4476]: Initializing "/usr/lib/x86_64-linux-gnu/qt5/plugins/plasma/kcms/systemsettings/kcm_mouse.so" 2023-04-01T11:51:07.884147-03:00 orion kded5[4476]: Initializing "/usr/lib/x86_64-linux-gnu/qt5/plugins/plasma/kcms/systemsettings/kcm_touchpad.so" 2023-04-01T11:51:07.884468-03:00 orion kded5[4476]: kcm_touchpad: Using X11 backend 2023-04-01T11:51:07.885260-03:00 orion kwin_x11[2328]: qt.qpa.xcb: QXcbConnection: XCB error: 3 (BadWindow), sequence: 6268, resource id: 60817413, major code: 18 (Ch> Here's some more information, though if there's anything else I can provide to help resolve this, please let me know: root@orion:~# dmesg | grep -i Trackpoint [ 535.610685] psmouse serio1: trackpoint: IBM TrackPoint firmware: 0x0e, buttons: 3/3 [ 535.661460] input: TPPS/2 IBM TrackPoint as /devices/platform/i8042/serio1/input/input20 Since the Trankpoint works perfectly in KDE under FreeBSD detecting it as "TPPS/2 IBM TrackPoint", I think this is more of a software problem than a hardware one. Thanks in advance. Kind regards, Daniel
