@NoDiskNoFun: I managed to install Arch on my CB5-311 by using instructions and scripts from
https://www.tbi.univie.ac.at/~ronny/acer-cb5-311.htmlThis gave me a usable System with the XFCE desktop. But because it is using an Nvidia driver that only supports an older X version, it had to install several downgraded packages (xorg-server etc), and in order to satisfy dependencies when I tried to update the system I had to add five more packages to the IgnorePkg line in pacman.conf: xf86-input-joystick, xf86-input-keyboard, xorg-server-xvfb, xf86-input-mouse, and xf86-video-fbdev. The system was working ok, but I could not start KDE, probably because of the outdated xserver, and I did not like using the outdated packages... so I'm trying to switch to the mainline kernel too.
Now KDE is working, but more important features are not! With the 4.8.1-2 kernel, whether self-compiled or from the repository (builduser@leming) I had neither USB nor Wifi!
Your post, NoDiskNoFun, inspired me to use the 4.8.0-rc8-1-ARCH kernel from the repository, because your dmesg had less usb errors in it. With 4.8.1-2 I get:
$this->bbcode_second_pass_code('', '
[ 1.878305] tegra-xusb 70090000.usb: Direct firmware load for nvidia/tegra124/xusb.bin failed with error -2
[ 1.878325] tegra-xusb 70090000.usb: failed to request firmware: -2
[ 1.878333] tegra-xusb 70090000.usb: failed to load firmware: -2
[ 1.879622] tegra-xusb: probe of 70090000.usb failed with error -2
')
...where with the rc kernel I get:
$this->bbcode_second_pass_code('', '
[ 6.859749] tegra-xusb 70090000.usb: Firmware timestamp: 2014-09-16 02:10:07 UTC

[ 6.860850] tegra-xusb 70090000.usb: irq 342, io mem 0x70090000
')
With usb I can at least get network access through a usb-ethernet adapter. But what can I do to get Wifi back to work? I read something about disabling a device that confuses the network manager?
X is running with kernel modesetting und the 'fb' driver, according to /var/log/Xorg.0.log - can anyone give me a tip on how to make use of Nouveau?
