The Arch Linux modifications for 3.13 can be found at: http://pastie.org/8763538 The patches used are the same as for 3.12 in this version: # Use Benson Leung's post-Pixel Chromebook patches: # https://patchwork.kernel.org/bundle/bleung/chromeos-laptop-deferring-and-haswell/ echo "Applying Chromebook Haswell Patches..." for patch in 3078491 3078481 3074391 3074441 3074421 3074401 3074431 3074411; do wget -O - https://patchwork.kernel.org/patch/$patch/raw/ | sed 's/drivers\/platform\/x86\/chromeos_laptop.c/drivers\/platform\/chrome\/chromeos_laptop.c/g'| patch -p1 done The paradox is I keep reading claims such as: https://plus.google.com/114358706658341629084/posts/Q9B4DiqWZ5E "As far as I can see, 3.13 has all the patches(including touchscreen model and touchpad) except the patch that defines what hardware config to use for the c720[p](the one in the chromeos_laptop.c file)." Yet the working 3.13 script uses all the 3.12 patches and uses the chrome subdirectories whereas in 3.12 the module used to be built and installed under x86. There is also an additional patch for the touchscreen c720p version of the Acer Chromebook, that I can't test because I don't have the touchscreen, discussed at: https://bugzilla.redhat.com/show_bug.cgi?id=1045821 To summarize, to get the touchscreen Acer Chromebook c720p working out of the box with Debian, at least three additional patches need to be applied. There is a claim that six patches have already been applied upstream, but basically that should be ignored and the original six patches should still be applied only modified to be applied in a new subdirectory. And in addition there are additional scripts discussed at https://wiki.archlinux.org/index.php/Acer_C720_Chromebook that need to be installed for say suspend to work. There are two different ways to implement these scripts, one way I believe is more recent systemd related. I use a different version from: https://bbs.archlinux.org/viewtopic.php?pid=1364376#p1364376 For this second solution there is a new script: /etc/pm/sleep.d/05_Sound edited /etc/rc.local, and edited /etc/default/grub, the grub modification I use being GRUB_CMDLINE_LINUX_DEFAULT="quiet splash tpm_tis.force=1" and not the longer version discussed at the Arch Linux wiki. >From the Arch Linux wiki I for better trackpad usability I add: /etc/X11/xorg.conf.d/50-cros-touchpad.conf Section "InputClass" Identifier "touchpad peppy cyapa" MatchIsTouchpad "on" MatchDevicePath "/dev/input/event*" MatchProduct "cyapa" Option "FingerLow" "10" Option "FingerHigh" "10" EndSection -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of "unsubscribe".
