Most recent kernel where this bug did not occur: 2.6.11 Distribution: Debian 3.1 Hardware Environment: Toshiba satellite 2410 Software Environment: KDE Problem Description: Since the kernel 2.6.12, i have a problem with my touchpad. In Kde, the menus disappear. In thunderbird, if i go to my last message and that i use my touchpad, it returns at the beginning. But when i put these lines in comments, all is correct. But not the scroll. (Option "ZAxisMapping" "4 5") Section "InputDevice" Identifier "Configured Mouse" Driver "mouse" Option "CorePointer" Option "Device" "/dev/psaux" Option "Protocol" "ImPS/2" #Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" Identifier "Generic Mouse" Driver "mouse" Option "SendCoreEvents" "true" Option "Device" "/dev/input/mice" Option "Protocol" "ImPS/2" #Option "ZAxisMapping" "4 5" EndSection In 2.6.11, it's ok. Thanks, Patrick
The xf86config/xorg.conf excerpt you added is clearly incorrect. You're not supposed to use /dev/psaux and /dev/input/mice at the same time - they'll supply you the _same_ data. This will result in every event happening twice, causing doubleclicks and other mayhem. Delete one of the sections OR change the driver to the 'synaptics' GPL driver. It's possible Debian doesn't ship it, as it is not a part of X, but you can find it on Google easily.
I use xserver-xfree86... XF86Config-4 With the kernel 2.6.11 and my two sections, all its ok. I only installed the kernel 2.6.13. I removed one of the section (Generic mouse) but nothing changes. I will change my drivers........
I didn't notice you mentioning that commenting out ZAxisMapping helps. There might be a problem in the kernel decoding the mouse data after all. What does cat /proc/bus/input/devices say? Did you try running 'evtest'?

No, i do not know it. I installed it with the package: DVB-UTILS http://packages.debian.org/testing/misc/dvb-utils I tested: evtest /dev/psaux evtest: can't get version: Inappropriate ioctl for device
To use evtest, do: modprobe evdev evtest /dev/input/event0 evtest /dev/input/event1 evtest /dev/input/event2 And verify the mouse scrollwheel works correctly and that the touchpad does, too.

Great, so that's the cause of the problem. The touchpad emits scroll data, even when it's not supposed to. The problem is that a Toshiba satellite 2400 had the same touchpad (at least reporting the same version) built-in, but that included a scrollwheel. Your doesn't. Please edit linux/drivers/input/mouse/alps.c and remove ALPS_WHEEL from line 46, replacing it with 0. It should help. Dmitry, we'll have to go for a DMI-based probing in the ALPS driver probably, after all.
I am not sure if it is practical - there are nmyriads of boxes using ALPS topuchpads and it seems there are unlimited number of its permutations :( I wonder if we check the first data packet after we detect "wheeled" touchpad and see that it reports wheel dtata we should just reset that flag... Not the best solution but I think it would work quite reliably in this case. We can even try polling the touchpad so we wont get real motion data packet but most likely "zero" one.
Please edit linux/drivers/input/mouse/alps.c and remove ALPS_WHEEL from line 46, replacing it with 0. It should help. Its ok but my scrollwheel not function.
What scrollwheel? On your external mouse? Did you put the ZAxisMapping back in?
Do you have a scrollwheen on your touchpad too?
On my touchpad, i have a scrollwheel and my ZAxisMapping is ok. Comment #6: when i wheel: if i wheel up, scroll up Event: time 1125418857.010330, type 2 (Relative), code 8 (Wheel), value 7 Event: time 1125418857.010342, type 0 (Reset), code 0 (Reset), value 0

Just to make sure, you code looks like this, right? if ((priv->i->flags & ALPS_WHEEL) && (packet[0] & 0x70)) input_report_rel(dev, REL_WHEEL, ((packet[0] >> 4) & 0x07) | ((packet[2] >> 2) & 0x08)); What does evtest show when you use touchpad's scroll wheel on an unpatched kernel?
ok me i have to add: {} if ((priv->i->flags & ALPS_WHEEL) && (packet[0] & 0x70)){ input_report_rel(dev, REL_WHEEL, ((packet[0] >> 4) & 0x07) | ((packet[2] >> 2) & 0x08)); } Unpatched kernel: if i wheel up, scroll up Event: time 1125418857.010330, type 2 (Relative), code 8 (Wheel), value 7 Event: time 1125418857.010342, type 0 (Reset), code 0 (Reset), value 0 Event: time 1125418857.025923, type 2 (Relative), code 8 (Wheel), value 7 Event: time 1125418857.025934, type 0 (Reset), code 0 (Reset), value 0 Event: time 1125418857.294821, type 2 (Relative), code 8 (Wheel), value 7 Event: time 1125418857.294831, type 0 (Reset), code 0 (Reset), value 0 Event: time 1125418857.341836, type 2 (Relative), code 8 (Wheel), value 7 Event: time 1125418857.341844, type 0 (Reset), code 0 (Reset), value 0 but if i wheel down, scroll up Event: time 1125419141.603488, type 2 (Relative), code 8 (Wheel), value 2 Event: time 1125419141.603498, type 0 (Reset), code 0 (Reset), value 0 Event: time 1125419141.871168, type 2 (Relative), code 8 (Wheel), value 2 Event: time 1125419141.871180, type 0 (Reset), code 0 (Reset), value 0 Event: time 1125419142.170949, type 2 (Relative), code 8 (Wheel), value 2 Event: time 1125419142.170960, type 0 (Reset), code 0 (Reset), value 0 Event: time 1125419143.148597, type 2 (Relative), code 8 (Wheel), value 2 Event: time 1125419143.148610, type 0 (Reset), code 0 (Reset), value 0 Event: time 1125419143.369900, type 2 (Relative), code 8 (Wheel), value 1 Event: time 1125419143.369908, type 0 (Reset), code 0 (Reset), value 0 Event: time 1125419143.385187, type 2 (Relative), code 8 (Wheel), value 1 Event: time 1125419143.385199, type 0 (Reset), code 0 (Reset), value 0 Event: time 1125419143.566468, type 2 (Relative), code 8 (Wheel), value 2 Event: time 1125419143.566478, type 0 (Reset), code 0 (Reset), value 0
Does it work any better if you change input_report_rel like this: input_report_rel(dev, REL_WHEEL, ((packet[2] >> 2) & 0x08) - ((packet[0] >> 4) & 0x07));

The real fix should likely be input_report_rel(dev, REL_WHEEL, ((packet[2] >> 4) & 0x04) - ((packet[0] >> 4) & 0x03));
Oops, I meant input_report_rel(dev, REL_WHEEL, ((packet[2] >> 4) & 0x04) - ((packet[0] >> 4) & 0x03));
Damn a typo again. This is it. input_report_rel(dev, REL_WHEEL, ((packet[0] >> 4) & 0x04) - ((packet[0] >> 4) & 0x03));
Its ok!!! A <b>big big</b> thanks to you, Dmitry and Vojtech. The changes: if ((priv->i->flags & ALPS_WHEEL) && (packet[0] & 0x70)){ input_report_rel(dev, REL_WHEEL, ((packet[0] >> 4) & 0x04) - ((packet[0] >> 4) & 0x03)); } if (priv->i->flags & (ALPS_FW_BK_1 | ALPS_FW_BK_2)) { *** Linux forever *** Patrick
Does it still work if you drop "&& (packet[0] & 0x70)" part of condition? It does not look right given Vojtech's suggestion.
And please also verify that when moving very fast up it doesn't start scrolling down or vice versa. We've changed the scrollwheel data from 4 to 3 bits, and thus it theoretically could overflow, if it's 4 bits in reality.
When i scroll up very fast, it scroll down. When i scroll down very fast, it scroll up.
Then it's really 4-bit and we need to find out the 4th bit.
I'm a fool. The right (4-bit) entry should obviously be input_report_rel(dev, REL_WHEEL, ((packet[0] >> 4) & 0x07) - ((packet[2] << 1) & 0x08));
ok Vojtech, i check... Dmitry, if I drop "&& (packet[0] & 0x70)", Its ok!!!!
Alright, please use that fix for now, the next kernel shall have it, too.
-> Resolved
When i scroll up, it scroll down When i scroll down, it scroll up. its to reverse.
I guess I have my bad day. This should work then: input_report_rel(dev, REL_WHEEL, ((packet[2] << 1) & 0x08)) - ((packet[0] >> 4) & 0x07);
And one more fix: input_report_rel(dev, REL_WHEEL, ((packet[2] << 1) & 0x08) - ((packet[0] >> 4) & 0x07));
Scroll up = Ok Scroll down = Ok Scroll down fast = Ok Scroll up fast = A small scroll down
Can you log the fast scroll down with evtest? Thanks.
Err, fast scroll up, resulting in small scroll down.

Patrick, 2.6.14 was released with the fix. Could you please confirm that the stock kernel works for you and if so close the bug? Thanks!
yes, it's ok!!! Thanks
