Questions[lenovo](ubuntu)

Fresh install of Ubuntu 18.04 on a new Lenovo x1c6, I'm getting this error sometimes after resuming from suspend.

I have no idea what it means, and search online leads to a bug report that doesn't exist

Might be related: my battery life is 4-5 hours, and this Lenovo is reported by other Ubuntu users to have 10+ hours. See related thread

The answer in that thread suggests running the following:

His problem was caused by fixed his high CPU problem by doing this:

I fixed it by adding a pci=nomsi parameter to the GRUB_CMDLINE_LINUX_DEFAULT property(you can find and edit it in: sudo vim /etc/default/grub)

After adding the parameter update the grub: sudo update-grub and then reboot. Then run top in the terminal, and see whether that fixed it.

I don't want to mess with grub without further advice. Too many bricked computers running around these days :)

Thanks in advance for any help!

After upgrade from 17.10 to 18.04, any device I connect to only stays connected for a couple of seconds. My laptop is a Lenovo P50 (20ENCTO1WW)

/var/log/syslog reports:

pulseaudio[????]: [pulseaudio] bluez5-util.c: Information about device /org/bluez/hci0/dev_???????? invalid
bluetoothd[????]: Endpoint replied with an error: org.bluez.Error.InvalidArguments

Obviously the question marks represent some id's (pid's and bluetooth id in this case)

Any clue on fix or workaround?

I have a Lenovo Yoga 910-13IKB. I was running Ubuntu 17.10 with no issues. I upgraded to 18.04 LTS and now my right-click on my touchpad does not register. I can only left-click.

I already tried the steps listed here, but they did not fix the issue.

Does anyone know how to fix this?

Thanks.

I have a new Lenovo E540 which has the special keys like volume change and such on the F-Keys here. So to actually use the F-Keys the FN has to be pressed to, so when using Alt+F4 I have to press Alt+Fn+F4 which is very inconvenient. In the BIOS it is possible to swap the FN and Ctrl Keys so the F-Keys are primary again but then the functionality of the Fn and Ctrl Key are really swapped! Is there probably a solution where the functionality of the FN and Ctrl key remain and the F-Keys are primary?

Is there a way to save my monitor settings? I have an external monitor at work, but each morning i have to plug it in, rearrange the windows from being side by side to being on top of each other. Can I just save this?
