I am new to Ubuntu and not very familiar with it. My Problem:

I want to run Ubuntu 17.10 on my Surface Pro 2017. I have installed the linux-surface kernel from jakeday which works fine. The most things work out (touch, display port, ...) except the power and volume button which isn't a problem for me. The thing I cannot live with is that the battery status isn't shown. I'm not sure where the problem arises, since it already existed after the custom installation of Ubuntu.

I think this relates to a error I get while booting the system. The log files includes the following errors:

/var/log/kern.log

Mar 13 08:12:25 daniel-Surface-Pro kernel: [    6.922232] ACPI Error: No handler for Region [OR01] (0000000046bb44e5) [GenericSerialBus] (20170831/evregion-166)

Any help would be awesome, thanks guys!

The problem is known, this is a reported issue in Jakedays' Github repository (see https://github.com/jakeday/linux-surface/issues/195) and a "missing driver" bug at kernel.org: https://bugzilla.kernel.org/show_bug.cgi?id=198145. As I have the same problem, I'm waiting for a driver as well.

Second thing, the "not authorized"-error in your syslog is not ACPI-related but a problem of automatic brightness. See /var/log/auth.log for details:

Jun 6 08:39:11 sp pkexec[7071]: gdm: Error executing command as another user: Not authorized [USER=root] [TTY=unknown] [CWD=/var/lib/gdm3] [COMMAND=/usr/lib/gnome-settings-daemon/gsd-backlight-helper —set-brightness 3450]

This bug is "confirmed" here: https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/1584457 and a quick solution would be

systemctl stop iio-sensor-proxy.service

I hope this helps in the meantime, while waiting for ACPI drivers!
