[PATCH] Input: introduce 'notimeout' blacklist for Dell Vostro V13
Description Marcin Naglik 2010-02-28 21:14:24 UTC
Exists in most recent kernel including 2.6.33 Distribution: Ubuntu 9.10, 9.04, 10.04 (alpha 3) Hardware Environment: Dell Vostro V13 laptop Software Environment: Linux marcin-laptop 2.6.32-020632-generic #020632 SMP Thu Dec 3 10:58:45 UTC 2009 i686 GNU/Linux Problem Description: The touchpad is recognized with i8042.nomux option however complately not working dmesg logs tons tons of: psmouse.c: bad data from KBC - timeout when clicking, tapping the touchpad Steps to reproduce: Run the system with i8042.nomux option. Running without i8042.nomux detects the touchpad as PS/2 Generic Mouse. I did quite huge research on the topic and know that other people have the same problem on their Dell Vostro V13. Tested all the i8042.xxx options, other ACPI options. Also tested number of bios settings (including disable usb legacy support). Also did upgrade to A02 (newest Dell bios for the machine)

I have the same problem with the same laptop (dell vostro v13 13.3") as the reporter. My kernel is the default ubuntu 10.04: 2.6.32-22-generic There is an ubuntu bug* #380126, where lot of v13 users confirms this bug, but not much additional info is there. I tried to digg a bit more. I read* on bug #6105 , that maybe psmouse.rate=40 helps, so I modified /etc/default/grub line: GRUB_CMDLINE_LINUX="" to: GRUB_CMDLINE_LINUX="psmouse.rate=40 i8042.nomux=1" Then sudo update-grub, and rebooted. The result is lot of [ 86.110461] psmouse.c: bad data from KBC - timeout *when* I move the mouse around it adds to the dmesg line. The mouse pointer stays at the middle of the screen and does not move. (it is not working in gdm either) I have attached a dmesg output, dmesg_psmouse_10.txt. I also redid with psmouse.rate=20 and 10 too. -- I have also read* on bug #496314, I should test my touchpad with evtest ( http://people.freedesktop.org/~whot/evtest.c ) program. So I downloaded, and tested it. The result is attached as evtest_output.txt. I tested it with sudo ./ev /dev/input/event10, as in file /proc/bus/input/devices shows the ps/2 mouse as event10. I also attached my /proc/bus/input/devices output as devices.txt If there are any other test, what I can do, just ask.

Comment 7 Eugenia Loli-Queru 2010-12-28 08:21:46 UTC
I think the bug is with the touchpad itself. I uninstalled DELL's in-home tweaked driver on Win7, and installed Synaptics' generic driver, and even Synaptics itself on Windows thinks that this is a PS/2 mouse and not a touchpad! So I think the bug is with either the BIOS or the firmware of the touchpad, advertising itself as a mouse... There are a myriads of bug reports about it on Ubuntu, Red Hat, and Mandriva, and many forum posts too, but I think the only thing it can be done is to hardcode the Product ID on the Linux synaptics driver in order to recognize it as a touchpad and not as a PS/2 mouse -- just like DELL did it for its own Windows drivers. I don't know what the policy is on Linux though about getting around buggy hardware.

Hello J(In reply to comment #8) > Created an attachment (id=41862) [details] > [PATCH] Input: introduce 'notimeout' blacklist for Dell Vostro V13 > > Testing with this patch would be appreciated. Patch tested yesterday on a 2.6.32 kernel (linux LMDE; debian style box), good news, now I have a fully functional synaptics touchpad on the Vostro V13, many thanks!!! now my touchpad is identified as SynPS/2 Synaptics TouchPad in gpointing-device-settings, and I could define all options like vertical, horizontal and circle scroll, I can now also use zoom with 2 fingers in apps that support this feature. Very happy to get back a fully functional Touchpad For others to test, I commented my installation here : https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/380126?comments=all Once again, many thanks && Happy new year!
Comment 10 Dmitry Torokhov 2011-01-06 10:10:43 UTC
There was one report that with the patch applied touchpad is dead on resume, could you please verify that shutdown and suspend/resume work properly? Thanks.
Comment 11 diroots 2011-01-06 10:44:05 UTC
I did not shutdown since I installed the patch, but I closed my screen last night and my computer went to suspend. and this morning, touchpad is still working. was the report of the dead touchpad for a 2.6.32 kernel?

Comment 14 Andrea Cimitan 2011-02-08 16:56:29 UTC
I have this bug with ubuntu mainline kernel, is somewhat related to this? https://bugs.launchpad.net/ubuntu/+source/linux/+bug/715267
Comment 15 Dmitry Torokhov 2011-02-08 18:04:08 UTC
Andrea, was this happening before or is it just started to happen?
Comment 16 Andrea Cimitan 2011-02-08 18:08:32 UTC
didn't happen with patched 2.6.37, don't know if it's related to ubuntu or vanilla 2.6.38
Comment 17 Dmitry Torokhov 2011-02-09 00:22:56 UTC
2.6.37 patched with what? This particular patch?
Comment 18 Andrea Cimitan 2011-02-19 14:28:48 UTC
@17 yes and I can confirm the bug with latest ubuntu natty kernel
Comment 19 Dmitry Torokhov 2011-02-22 22:05:22 UTC
Ok, so if patched mainline works then please ask Ubunty guys to backport it to their kernel.
