btnx: Send keyboard and mouse combination events with mouse buttons

The cat command you gave wouldn't have worked without a "sudo" or without running as root. But it should have given a "permission denied" error.
What version of Ubuntu are you running?

Try modprobing evdev.

Code:

sudo modprobe evdev

If you have rebooted your computer since you last looked at /proc/bus/input/devices, then find the event name again. Then search for that event name:

Code:

sudo find /dev -name *event3*

Replacing event3 with whatever it is at the moment.

A model troubleshooting post, by the way. I think I'll make a link to your post to show what information should be provided.

I rebooted and now it is on event6

When I run btnx, it still doesn't work. event6 doesn't exist in /dev/input/

Code:

alex@host:~/btnx-0.2.6$ sudo find /dev -name *event6*
/dev/.udev/names/input%2fevent10/%2fclass%2finput%2finput6%2fevent6/dev/.udev/names/input%2fby-path%2fpci-0000:00:1d.3-usb-0:2:1.0-event-mouse/%2fclass%2finput%2finput6%2fevent6
/dev/.udev/names/input%2fby-id%2fusb-Logitech_USB_Receiver-event-mouse/%2fclass%2finput%2finput6%2fevent6
/dev/.udev/db/%2fclass%2finput%2finput6%2fevent6

I initialized evdev by doing this:

Code:

sudo modprobe evdev

It runs but doesn't have any ouptut, I'm positive that evdev is installed. I was using it previously.

I even tried linking one of the /dev/.udev/ files to event6

Code:

alex@host:~/btnx-0.2.6$ sudo ln -s /dev/.udev/names/input%2fby-path%2fpci-0000:00:1d.3-usb-0:2:1.0-event-mouse/%2fclass%2finput%2finput6%2fevent6 /dev/input/event6

After I did this, I ran btnx as root and btnx segfaulted

Code:

alex@host:~/btnx-0.2.6$ sudo ./btnx 
Detected mouse: mxrevo  Vendor=046d Product=c51a
Device and event handler detection complete.

Opened handler: /dev/input/event6
Opened handler: /dev/input/event7

I'm running Ubuntu 7.04, upgraded from 6.10. It's pretty much a regular install, I didn't use automatix or anything like that.

When I run btnx, it still doesn't work. event6 doesn't exist in /dev/input/

Try hexdumping the event handlers in /dev/input/by-id and /dev/input/by-path

Code:

$ sudo cat /dev/input/by-id/somename | hexdump

Move your mouse and see if one of them outputs any data.

I hexdumped all of them.

When I run:
alex@host:~$ sudo cat /dev/.udev/db/%2fclass%2finput%2finput6%2fevent6 | hexdump

It outputs the same info every time, regardless of whether the mouse moves. In fact, it outputs if the mouse doesn't even move.

**RVDowning** · June 2nd, 2007

I don't know what your xorg.conf looks like now, but looking at the old one, I think you should try to do the following (making a backup first):
Merge your InputSections into one input section.
Remove evdev as the driver, use something more generic like "mouse"
Remove references to the product and vendor IDs
Use protocol "auto"
Use device "/dev/mouse" (assuming this is where that device is located in Mandriva).
Remove the HWheelRelative option, adding it later if necessary.
I hope it works out.

Actually my xorg.conf looks exactly the way you wanted. I added "modprobe uinput", a directory change, and ./btnx to /etc/rc.d/rc.local for Mandriva 2007.1 so that stuff would auto load.

Now I think I will add in revoco, and will have the "coolest mouse in town."

Thanks much for all your help.

**blazoner** · June 4th, 2007

OK, I've been playing around with the settings a bit, and have noticed that you have gotten the shortcuts for firefox back/forward switched around.
KEY_LEFT & KEY_LEFTALT should be back in history, and KEY_RIGHT & KEY_LEFTALT should be forward.

Well I finally have a day off and I am trying btnx. I does reconize my mouse but does not work. I have read through all the posts so far. Here is all the info I can give you

Code:

sam@samstoy:~/btnx-0.2.6$sudo ./btnx

Did not find additional event handlers. No problem.

There is no event2 in /dev/input

Some problems with my MX 600 on a fresh 7.04 install:

1. Ctrl+Alt+Right (rear thumb button) only works if the mouse is over the desktop itself, not when it is over any window (firefox, OOo, etc.) Ctrl+Alt+Left works both on the desktop, and in windows, as per normal behavior.

2. The 100% button still only acts like a Left click, except in terminal, where it outputs the same as a middle click. I extended that delay to as much as 150 with no noticeable improvement.

3. The 100% button, the rear thumb button, and the left scroll wheel press, all register as paste (middle click) in terminal, and the left scroll wheel press then outputs a "C". This seems to be the common denominator between the buttons that are giving me problems.

Well, I've tried my MX 600 with both of my PC's now, and the problems are consistent with both, as are the hexdumps. I have no clue what to try next, so I'm including a text file with all the results I've accumulated so far.

Here's what's not working:

1. Ctrl+Alt+Right (rear thumb button) sometimes works if the mouse is over the desktop itself, not as often when it is over any window (firefox, OOo, etc.) Ctrl+Alt+Left works both on the desktop, and in windows, but only sometimes. ***This behavior is extremely sporadic, and the only way to make it work every time is to click and hold the right button first.

2. The 100% button acts like a wheel click. I extended that delay to as much as 500 with no noticeable improvement.

**sjust** · June 5th, 2007

I just want ot let every one know that I fixed my problem. It seems the I forgot about a rules.d file from a previous configuration. Once I got rid of that btnx works great.
