Problem with Synaptics under Linux Kernel 2.6.15 [Solved]

Message

KeyserZero · Post by **KeyserZero** » Thu Jan 12, 2006 6:47 pm

Hey all!

I have installed the new Linux Kernel 2.6.15 for wifi support.

After reboot and all that stuff my system works well again expected my touchpad. The touchpad works normal but i haven't Synaptics support.

Thanks for the help

did you compile evdev support in your kernel?

KeyserZero · Post by **KeyserZero** » Thu Jan 12, 2006 7:38 pm

Yep, evdev is in kernel

hmm... and you're sure you have everything else that you would need? USB_HID, USB_HIDINPUT, & USB_MON? It's easy to miss USB_MON.

Is the module getting loaded?

It's easier to pinpoint the problem if you tell us what you're doing and what happens when you do it.

Thanks for the help!

The touchpad works well, i use the Appletouch driver from the Kernel.

But know i would like to use the Synaptics driver with the touchpad.

Bevore i upgraded my Kernel from 2.6.12 to 2.6.15 i have no problem with the Synaptics driver.

Have you upgraded synaptics lately? I ask because there was a version out there that didn't work for a lot of people. I'm using 0.14.3 here.

The symptoms were different (X woldn't start) but people were having trouble with 0.14.4. It might be worth it to go down to 0.14.3

With a gentoo-sources 2.6.14-r5 kernel I have no problems.

About the synaptics-0.14.4 problem, I know that an older revision didn't work, so I downgraded to 0.14.3. The current revision -r2 works on kernel 2.6.14.

Check dmesg to see whether synaptics is loading properly. If it is, you will be able to read touchpad output on /dev/input/mice (using xxd or another hexdump).

mustard · Post by **mustard** » Sat Jan 14, 2006 4:38 pm

using less -f /dev/input/mice gives gibberish on screes when i move the mouse, so i guess it's going

AbsturZ · Post by **AbsturZ** » Mon Jan 16, 2006 12:41 pm

I had a similar problem using synaptics on suspend2-sources-2.6.15-r?.
the solution was:

Code: Select all

mknod /dev/input/event1 c 13 65

(remember to adjust to your needs) and to turn SHMConfig off.
I hope this will solve it for you too.

KeyserZero · Post by **KeyserZero** » Mon Jan 16, 2006 6:22 pm

Hey all!

I have found the answer for the synaptics problem!

With the 2.6.14 Kernel the evdev module was loaded automatic at boot.

Now with the 2.6.15 Kernel the module wasn't loaded at startup.

Code: Select all

modprobe evdev

Now it works =)

Thanks for the help

skerb1 · Post by **skerb1** » Tue Jan 17, 2006 6:15 am

Also using 2.6.15 and this problem is not solved for me. What else did you do? I don't need to load the evdev module since I have it directly compiled into the kernel and I am still seeing the same problem...I'll try updating some of my software (synaptics driver, etc...)

Edit...
Ok so after updating my system with

Code: Select all

emerge --update --deep --newuse world

there had been no change. I have evdev compiled into the kernel. By the way there is no problem I am having with a pre 2.6.15 kernel.

@skerb1

Pleas post your X log

skerb1 · Post by **skerb1** » Tue Jan 17, 2006 4:26 pm

I think the issue is here is that the 2.6.15 kernels must have changed some API because now my
/dev/input/eventX devices are not being created as they were for < 2.6.15 kernels. Seems like
this is a bug in the kernel code. It would seem like this is the same problem that KeyserZero had
but I have evdev build into the kernel directly.
