ACPI Error, two finger scrolling failure, on ThinkPad E480

A new Lenovo ThinkPad E480 laptop showed errors like PCI Bus error severity=Corrected among others. I searched for a solution and added the kernel boot parameter pci=nomsi permanently. The PCI error is solved, but there appears to be other errors as well:

[Do Okt 3 18:25:08 2019] Couldn’t get size: 0x800000000000000e

[Do Okt 3 18:25:42 2019] Bluetooth: hci0: unexpected event for opcode 0xfc2f

that was shown to me after typing dmesg -T -l err in the terminal.

I also had issues with keys of my keyboard that wouldn’t react or get locked like the F1 to F12 and the Esc key. Today they functioned correctly but scrolling with two fingers didn’t function even though it was set in the settings.

How may I troubleshoot to resolve these issues?

In Ubuntu 18.04 using thinkpad , how Settings application is launched when Fn + F9 is pressed?

In thinkpad X1 yoga , when i press Fn+F9 key , Settings Application is launched . Is this Genome Application ? If yes , Is it possible to launch some other application instead of “Settings” Application when Fn + F9 is pressed and how can we achieve it?

Thank you

Thinkpad T430, Ubuntu 18.04, No sound on startup sometimes

Sometimes I have sound when I start, sometimes I don’t. Rebooting has always fixed it so far…

Lenovo Thinkpad T430, Ubuntu Studio 18.04. No sound from headphones or speakers. Sound buttons on top panel don’t do anything.

I’d kinda like to have some tips on troubleshooting this from the terminal. ‘aprops’ suggestions, i.e.

Toggle caps lock LED on ThinkPad T43 – Ubuntu Server 16.04

I have installed the above mentioned OS on a 15-year old IBM Thinkbad (t-43 / 1871 series).

I only care about the CAPS lock LED. Don’t care about the others. Have reviewed some basic topics regarding setleds or similar but nowhere have I seen or understood exactly how to enable toggle. I have seen commands on how to manually turn the light on or off at will. That’s silly, why should I have to do that. I want it to work the way it’s supposed to: toggle on/off so that I know when I’m in caps on or caps off mode.

Can anyone suggest what amendments I need to make so that I can enable it? I would prefer solutions that don’t require downloading extra software (remember this is a text-only interface that I have) as I want to keep the system light. I could do with some light scripting I suppose, but I’m really hoping there is a line somewhere in a system file that I need to amend to make this work. Otherwise open to some more involved solutions I guess. Thanks!

As a bonus, I’d like to get rid of a weird blinking that I get from the wifi LED (even though I think I disabled it from IBM’s BIOS). Any other suggestions on how to experiment with other similar features: Modify the behavior of the fan? I don’t need it to work constantly. server sees very light usage. is this a good idea?

Ubuntu Brightness problem on Lenovo ThinkPad T495

I recently got a Lenovo ThinkPad T495 where I dualboot Ubuntu 18.04.

Unfortunately I cant adjust the screen brightness.

I have already tried with this solution ( Brightness problem Ubuntu 18.04 LTS ) but with no luck, could you help?

The acpi_backlight=video option seems to be closer to solution for me in the sense that at least the brightnes bar goes up and down properly when applying this fix (only the bar changes not the actual brightness!), but I guess my configuration file should look a bit different from the one provided in the link.

When I run the “sudo lshw -c video | grep ‘configuration'” command to find out my graphic drivers I only gets answer: “configuration: latency=0”

Can you help?


VLC SDR 10 Bit 4k video stuttering in Ubuntu 16.04 on ThinkPad P52 with NVidia Quadro P1000

I have Ubuntu 16.04 LTS and Windows 10 installed on my ThinkPad P52.

Hardware configuration is –
Processor: i7 8750H (6 cores, 12 threads)
RAM: 16 GB 2400 MHz
NVME Drive: Samsung NvME EVO Plus 500GB
GPU: NVidia Quadro P1000 (Mobile)

enter image description here

I believe hardware configuration is more than enough to play 4k SDR videos with 10 bit encoding.

When I play SDR 4k 10 bit video using VLC 3 on Windows 10, it works perfectly smooth. But, when I play the same SDR 4k 10 bit video using VLC (both VLC 3 and VLC 4) on Ubuntu 16.04, it continuously stutters.

NVidia Graphics Driver on Ubuntu is already installed which is available in official repository. The version is 384.

Anybody know what’s the issue and how can I fix it?

xinput property ‘Synaptics Noise Cancellation’ doesn’t exist – Thinkpad x220 – jittery touchpad – ubuntu18.04.3

I just installed ubuntu on my thinkpad-x220 and my touchpad is extremely jittery / jumpy. If I don’t touch it my mouse stays still which is fine, but once I start moving my finger on the touchpad the mouse shakes and moves which is so annoying.

Apparently this is a well known issue, but I’m not having any luck using the recomended solution of xinput:

When I run xinput I see this:

I run this command:

xinput --set-prop "SynPS/2 Synaptics TouchPad" "Synaptics Noise Cancellation" 20 20 

but get an error message saying:
