Kernel 2.6 PS/2 mouse problem

chameleon · n00b Joined: 16 Aug 2002 Posts: 35 Location: Germany

Hi guys,

I just have another problem with my 2.6 kernel. My PS/2 mouse isn't running under it ... I tried to load psmouse as modul and built it directly into the kernel, nothing worked. A friend says that the problem comes with the SiS chipset that I've on my motherboard. Could that be true? Did anyone know how to fix this problem?

Problem solved. I've bought an usb mouse ... not really a good solution but the easiest one

That's exactly the problem I have.

I've got a latop with synaptics touchpad but mostly I use a PS/2 mouse.
The chipset is SiS7012.

I had the same problem... (on an Asus L8400-K laptop)

During config of the 2.6.0 kernel I selected ps2-mouse as a module and selected the synaptics driver too.
After booting the new kernel and starting XFree, the external ps2 mouse didn't work but the touchpad
did work! So I removed the synaptics driver from the kernel and recompiled, rebooted and now
the external ps2 mouse and touchpad are both working at the same time (like usual)...
But now my scrollwheel (on the external mouse) doesn't work anymore !

It worked flawlessly under 2.4.x and 2.5.x but for some reason 2.6.x seems to break it.
It's a simple Microsoft Wheelmouse with 2 buttons and a wheel that also acts as the 3rd button.
On the bottom of the mouse it says: "Wheel Mouse" Serial and PS/2 Compatible
It has a PS/2 connector and I'm not using the serial adapter that came with it.

The XFree config is absolutely correct because it works with 2.4.x when I reboot...

I've read almost all posts about scrollwheel problems after upgrading to the new 2.6.0 kernel.
Solutions for usb mouses seem to work great, but I haven't seen fixes for real PS/2 mice yet
except changing the protocol to IMPS/2 in /etc/X11/XFConfig. I already had this set
correctly and I'm still looking for a solution...

Please post if you have fixed this problem !

BTW, I've tried changing the device to /dev/mouse and /dev/input/mouse0 but the scrollwheel
won't work.

Finally... I have disabled the touchpad in my BIOS and now my external PS/2 mouse has a
working scroll wheel.

I think the touchpad is being identified as a normal PS/2 device and the ImPS/2 protocol is
being ignored. Weird !!!

I have a Dell Inspiron 4150 with a synaptics touchpad. I use a USB mouse as well. I included the PS/2 and touchpad support in the kernel. My touchpad works now, but I can't select or tap with it, the way I was able to do it with kernel 2.4!
BTW you can't use the PS/2 mouse and the touchpad at the same time because of the limitations of the PS/2 protocol, that's what I recall reading sometime ago

Sorry what I meant to say was that if you use a PS/2 mouse and touchpad at the same time, u might have problems when you use the touchpad alone. I had this problem when using the 2.4 kernel, so I got myself a USB mouse and left the PS/2 port only for the touchpad. If you have been able to use the touchpad+mouse and touchpad alone, please tell me how you achieved it!

You are right about that, I had problems too when using the touchpad without having the
ps/2 mouse connected! But I was able to fix that by downloading and installing a synaptics
driver for XFree. (I found out that there's an ebuild for it too: x11-misc/synaptics )

I have this in my /etc/X11/XFConfig:

hmm... I never tried that. Maybe I should. However I'm happy with my USB mouse now

Its also supposed to be friendlier for X according to the install guide.

BTW I got my touchpad working in 2.6 after following the instructions in the post that you mentioned.

thanks a lot!

I believe I have a bad kernel config. I cannot get a USB nor PS2 mouse to function under X. I'm not sure what to look for.

I get no output when I do cat /dev/psaux (for my ps2) nor cat /dev/input/mice (for my USB)...

I've tried 2 identical mother boards, both suffer from the same issue. Odds are it's a kernel config that I'm completely missing or I'm having a bad luck spree with the 2 mother boards. I should also mention that I've tried 2 different mice and both are known to be working.

I'm running a 2.6.0 kernel, asus A7A133 MB, AMD Athalon 1200MHz.

I too have problems in 2.6 (2.6.1-mm1) with my Synaptics touch pad and 3 button mouse plugged into my laptop's PS/2 port. Both worked fine at the same time in 2.4.

I tried to cat /dev/input/(everything there)

One of the events didn't work, one was for the keyboard, and they other worked for both the touchpad and (occasionally) the PS/2 mouse. I found I could get some output from the PS/2 mouse by moving and clicking around, but it would stop after a while until I moved my finger on the touchpad. At any rate, moving and clicking the PS/2 mouse in my WM wouldn't move the cursor, but it would occasionally trigger a right mouse event. I'm at work so I don't have all the info in front of me.

And, doing this (moving the PS/2 mouse) would result in a ton of messages in dmesg. Something about "Synaptics lost sync at byte 1" or something like that. Over and over and over... My computer didn't seem to like this. I started to recompile the kernel before going to bed and it was still plugging away in the morning. Normally, it takes about 1.75 hours on my K6.

So, for now I've unplugged the PS/2 mouse and use the Synaptics pad only. No more of the Synaptic messages in dmesg. I'll have to try a USB mouse later.

i just installed kde on my other machine and was confronted with the same symptoms: mouse loads fine, everything is beeing detected, but nothing moves or cries. is this a kernel bug?

update: just read somthing about "turning off usb support (for dos) " in bios. i'll give it a try.

update 2: yep. disable usb in bios, if you want ps/2 in X.

I seems mouse support in 2.6 is a bit different from 2.4 - Just for comnparison, I'm having trouble getting the mouse to work on a Sun Ultra 5 - and that hardware's about as different from the above ones as you can probably get....

Odd thing is after a boot up, the mouse doesn't work. - Solution - unplug it and plug it back in.

Wierd !!!

(works fine under 2.4 though)

It keeps telling me in the Log file the following

p.s. the following appears over 100 times in the same log file

Elf_RelocateEntry() Unsupported relocation type 9

AND

/usr/X11R6/lib/modules/input/synaptics_drv.o is unresolved
