[Bug 1433444] Re: Thinkpad T550 touchscreen does not work
I got a response back from the linuxwacom-discuss mailing list saying that the USB_DEVICE_WACOM(HID_ANY_ID) catch-all rule should be sufficient for an integrated device like this one. So the real solution is to just install a more recent kernel. The rest will depend on the X driver settings. Solution: Use a 3.18 or newer kernel. Here's what I've found so far: By default, the "wacom" driver is applied by 50-wacom.conf in xorg.conf.d. In this mode, you get normal single touches/drags and two- finger gestures (like scrolling and right click). There are a couple of alternatives I've found, and both have about the same result: three- and four-finger Unity gestures work (https://wiki.ubuntu.com/Multitouch), but two-finger gestures no longer work everywhere. Some applications seem to support two-finger scrolling while others don't. I can live with that, so I prefer to implement an alternative to enable the three- and four-finger gestures. Alternative 1: delete 50-wacom.conf or comment out the "Wacom class" so that X use the "evdev" driver instead of the "wacom" driver. Alternative 2: Add 'Option "Gesture" "off"' in the "Wacom class" section of 50-wacom.conf to disable in-driver two-finger gestures so that they will be passed up to X instead. (see http://linuxwacom.sourceforge.net/wiki/index.php/Multitouch#Disable_xf86 -input-wacom_In-driver_2FGT_Gestures). I haven't thoroughly tested these two alternatives to know if there are any other differences, but for now I'm using Alternative 2. Bug 1227214 seems to be covering the remaining matter of three- and four-finger gestures not working when running with the "wacom" driver without also disabling in-driver two-finger touches (and losing a lot of two-finger gesture functionality across the board in the process). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1433444 Title: Thinkpad T550 touchscreen does not work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-utopic/+bug/1433444/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1433444] Re: Thinkpad T550 touchscreen does not work
Notes: This touch screen reports itself as a Wacom USB device. This should be handled by the wacom_wac.c driver in the kernel. The 0x5010 Product ID is still not explicitly listed in wacom_wac.c as of the latest Linux kernel v4.0-rc4. However, it appears that a catch-all entry, USB_DEVICE_WACOM(HID_ANY_ID), was added to wacom_wac.c beginning in Linux kernel v3.18. This catch-all entry allows for basic touch support. Solution Needed: In order to get full support (e.g., multitouch), the wacom_wac.c needs to be updated with a description of the ThinkPad T550's Wacom device with Product ID 0x5010. Semi-functional workaround: Use a 3.18 or newer kernel. I used a v4.0-rc4 mainline kernel (https://wiki.ubuntu.com/Kernel/MainlineBuilds; http://kernel.ubuntu.com /~kernel-ppa/mainline/v4.0-rc4-vivid/) to workaround the issue on my Thinkpad T550, but I believe a kernel as early as 3.18 would work. My T550's screen accepts basic touches at least. Each touch is treated the same way it would be if it was a mouse cursor left-clicking at that spot (or left-button dragging if I do a drag). Workaround Note for Thinkpad T550 users: When I first booted the v4.0-rc4 kernel, my Wi-Fi stopped working. The newer kernel was looking for a newer iwlwifi-7065D-*.ucode firmware binary than what was installed in /lib/firmware in 14.04. To resolve this, I downloaded https://wireless.wiki.kernel.org/_media/en/users/drivers/iwlwifi-7265-ucode-23.15.10.0.tgz, unpacked it, and copied the iwlwifi*.ucode files into /lib/firmware. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1433444 Title: Thinkpad T550 touchscreen does not work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-utopic/+bug/1433444/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
