Same here, on a Dell Latitude E5420. According to "xinput list" this touchpad was seen as "Generic PS/2 Mouse", but it should be seen as an ALPS touchpad. I searched the internet for a solution, since this was bugging me a lot and I found this: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/760142 It looks like Dell is using these ALPS Glidepoint touchpads a lot in recent models and therefore this bug has the potential to affect a lot of people. In one of the last posts in this Ubuntu bug report is a link to the LKML archive: http://www.spinics.net/lists/linux-input/msg12507.html Apparently there is a patch for the kernel that fixes these problems, but I hasn't been accepted into the mainline kernel because it looks like it only fixes this for Dell laptops and not for every other laptop with this touchpad. (I have no idea if this is correct) Since the touchpad worked with a Ubuntu 11.04 Live system booted from a stick, I took a look at their kernel source and they integrate the above mentioned patch (without changes). So I rebuild the kernel SRPM (2.6.38.5-24) and included this patch. This custom build kernel recognizes the touchpad correctly: $ xinput list ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ ImPS/2 ALPS GlidePoint id=12 [slave pointer (2)] <== ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ Video Bus id=7 [slave keyboard (3)] ↳ Power Button id=8 [slave keyboard (3)] ↳ Sleep Button id=9 [slave keyboard (3)] ↳ Laptop_Integrated_Webcam_FHD id=10 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)] ↳ Dell WMI hotkeys id=13 [slave keyboard (3)] $ cat /proc/bus/input/devices … I: Bus=0011 Vendor=0002 Product=0005 Version=7326 N: Name="ImPS/2 ALPS GlidePoint" P: Phys=isa0060/serio1/input0 S: Sysfs=/devices/platform/i8042/serio1/input/input5 U: Uniq= H: Handlers=mouse0 event5 B: PROP=0 B: EV=7 B: KEY=70000 0 0 0 0 B: REL=103 … With the new 2.6.38.6-27.fc15.x86_64 the problem reappears, so I guess I'll be building another custom kernel tonight and run the old one until then. BTW: With 2.6.38.5-24 sleep and hibernation would not work on this laptop (the system would resume to a blank screen, would not resume network and the consoles didn't work either), but with 2.6.38.6-27 they do. I'm mentioning this, because the submitter of the kernel patch mentioned suspend/resume issues which supposedly are also fixed by the patch (they were partly fixed in my custom build kernel, resume worked 80% of the time). If you need more information, contact me. *** Bug 698461 has been marked as a duplicate of this bug. *** *** Bug 698805 has been marked as a duplicate of this bug. *** I've been testing this patch for a while now without issues. I've applied this patch and now the mouse is recognized as N: Name="ImPS/2 ALPS GlidePoint" The horizontal scrolling is working fine but on Gnome System Settings > Mouse and Touchpad the Touchpad sheet didn't appears Anybody knows if did I need something extra to fix this problem ?? Created attachment 512509 [details] Patch from http://thread.gmane.org/gmane.linux.kernel.input/16626 This patch has not been approved by the upstream (being too hardware specific hack, not a proper solution).

Interesting, please attach * your X server config file (/etc/X11/xorg.conf, and any other files in /etc/X11/xorg.conf.d/ if available), and * X server log file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file attachments using the bugzilla file attachment link above. We will review this issue again once you've had a chance to attach this information. Thanks in advance. Created attachment 512551 [details]
Xorg config Files and Log
As requested attached my xorg config and xorg logs.
I forgot to mention my laptop is a Dell Vostro 3550 Please let me know if you need anything else. Regards! Same as: https://bugzilla.redhat.com/show_bug.cgi?id=590880 The resolution is that one must patch the psmouse driver in order to make the touchpad behave more acceptably. No fully function multi touch driver exists, but I have been running the patch and it helps a lot. It is all explained toward the end of that bug mentioned above. This bug should be closed/merged with that one. *** This bug has been marked as a duplicate of bug 590880 *** |
