Last night I have installed an Ubuntu 16.04 into an USB stick, as one would normally install it into a hard disk. I've booted 16.04 from DVD and directed the install process to an USB key of 15.9 GByte which was visible for the installer as sdb. The installation went fine on the 3rd try. After rebooting the installed system from the USB key, I fetched and installed http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7-rc6-yakkety/linux-image-4.7.0-040700rc6-generic_4.7.0-040700rc6.201607040332_amd64.deb by just running sudo dpkg -i linux*.deb. After a reboot it says now: Linux tiny-ubuntu 4.7.0-040700rc6-generic #201607040332 SMP Mon Jul 4 07:34:26 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux With this new kernel 4.7 of July the Elan touchpad in the netbook Acer C720 is now visible as I: Bus=0018 Vendor=04f3 Product=005a Version=0000 N: Name="Elan Touchpad" P: Phys= S: Sysfs=/devices/pci0000:00/0000:00:15.1/i2c-7/7-0015/input/input15 U: Uniq= H: Handlers=mouse1 event15 B: PROP=5 B: EV=b B: KEY=e520 10000 0 0 0 0 B: ABS=663800013000003 We have no support in FreeBSD for this i2c device. Comments in the driver in Linux 4.7 say that is was written based on the cyapa driver which we have in CURRENT. I'm wondering about the elantech support which was recently added to the psm(4) driver, see: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=205690 but perhaps both are completely different devices with the same name. matthias -- Matthias Apitz, ✉ guru@unixarea.de, ⌂ http://www.unixarea.de/ ☎ +49-176-38902045 "Wer übersieht, dass wir uns den anderen weggenommen haben und sie uns wiederhaben wollen, kann von den Kämpfen der letzten Tage keinen verstehen.
