[Ubuntu-x-swat] [Bug 1219753] [NEW] Dell XPS 12 2013 Haswell synaptics trackpad not recognized anymore in Ubuntu kernel 3.10 and 3.11rc
Public bug reported: First I installed stock Ubuntu 13.04 Raring Ringtail with kernel 3.8. Trackpad was functioning correctly (e.g. two-finger scrolling worked) and was recognized as Synaptics device in /proc/bus/input/devices. Due to very new Intel wireless 7260 hardware that did not work in kernel 3.8, I had to upgrade my kernel to latest 3.11rc. With this kernel my Synaptics trackpad is no longer recognized as Synaptics and works as default evdev pointer (mouse) device, without all the trackpad features. I dist-upgraded to 13.10 Saucy Salamander with kernel 3.10 to see if it may have been fixed there. But unfortunately the trackpad regression is also there. Instead of Synaptics, devices lists it as below: I: Bus=0018 Vendor=06cb Product=2734 Version=0100 N: Name="DLL05E3:01 06CB:2734" P: Phys= S: Sysfs=/devices/pci:00/INT33C3:00/i2c-8/8-002c/input/input11 U: Uniq= H: Handlers=mouse0 event11 B: PROP=0 B: EV=17 B: KEY=3 0 0 0 0 B: REL=3 B: MSC=10 ProblemType: Bug DistroRelease: Ubuntu 13.10 Package: xserver-xorg-input-synaptics 1.7.1-0ubuntu1 Uname: Linux 3.11.0-031100rc7-generic x86_64 ApportVersion: 2.12.1-0ubuntu3 Architecture: amd64 Date: Mon Sep 2 11:52:16 2013 DistUpgraded: 2013-09-01 22:21:35,082 DEBUG enabling apt cron job DistroCodename: saucy DistroVariant: ubuntu EcryptfsInUse: Yes InstallationDate: Installed on 2013-08-09 (23 days ago) InstallationMedia: Ubuntu 13.04 "Raring Ringtail" - Release amd64 (20130424) MachineType: Dell Inc.

In fact my bug report is based on kernel v3.11-rc7-saucy with 13.10. Everything in my XPS 12 2013 seems to work fine with current Saucy development and kernel 3.11rc, *except* the trackpad.

Re: [Ubuntu-x-swat] [Bug 1104230] Re: DisplayPort 1.2 MST support is missing in the Intel driver
Hi Dariusz, I have a Dell XPS 12-9Q33 and two U2414Hb Dell displays, all DP 1.2 MST compatible. Using your instructions, I installed the new kernel and intel driver. Daisy chaining the two displays to my laptop DOES NOT work. With this kernel no external display works anymore. Moreover, my wireless network controller is now no longer working. Even though it's listed in lspci as a 'Network controller: Intel Corporation Wireless 7260 (rev 6b)', rfkill list shows nothing. Also, the touchscreen of my laptop stopped working with this kernel. It's no longer in the output of xinput list, which should show 'ATML1000:00 03EB:842F'. Lastly, my brightness keys don't work anymore. When I reboot with official kernel 3.13, everything works again. Of course, except for MST. Can you perhaps explain what's going on?
