Wireless not shown – Lenovo V145, Ubuntu 16.04

I received a Lenovo V145 with only FreeDos on it and installed Ubuntu 16.04 on it (Format everything). For some reason I cannot connect to a Wireless network

I think it is there but I am not able to see it (in the menubar). Same with the Bluetooth, even after I turn it on manually using the system settings icon.

Is there a hidden option that gives me the option to connect to Wireless?

UbuntuMATE on Lenovo MiiX320 – mobile broadband grayed out

I’ve installed Ubuntu-MATE 18.04 on a Lenovo MiiX320 by following this tutorial: UbuntuMATE auf MiiX320-10icr

It works fine, but I can’t connect by using the built-in Fibocom LTE modem. It’s displayed at the Network Manager applet immediately as a mobile broadband connection, incl. the provider and fieldstrength. However, the entry is grayed out and I can’t access it and so I couldn’t enable the connection. In the settings menu of the Network Manager, the connection is not listed. If I manually create a mobile broadband connection, the applet starts to flicker in the status line.

I’ve already tried to get help at the ubuntuusers forum, but unfortunately the best are now over with their ideas. Fibocom-LTE-Modem lässt sich nicht aktivieren

If you read the thread @ ubuntuusers, then you see what already has been queried and. Unfortunately there was no success. If anyone else has an idea (or maybe even the solution to the problem): I beg for it! 🙂

Can’t install Ubuntu on unallocated space (Lenovo with Windows 10)

Hello I’m currently trying to install Ubuntu 18.04.3 LTS on my laptop that already has Windows 10 Home edition as it’s main OS. I’ve read that it’s possible to create a dual boot system with both Windows and Ubuntu and so I looked for some guides online for help on the topic and I started:

  1. I created an ISO image in my USB stick with the ubuntu installer using rufus.
  2. I created an unallocated space using the partitioning app that Windows has.
  3. I rebooted my computer and selected my USB as the way to boot.
  4. I chose the option to Try Ubuntu without installing it.

Then everything works fine, I get to the desktop page of Ubuntu and the installer on it, i double click it and I choose English as the option to install and pick the normal installation but when I get to the part to choose where I want to install Ubuntu it’s just an empty list and the unallocated space is nowhere to be found.

I’m really new to using Ubuntu and I’d appreciate any help with this, ask me if I need to give more detailed information I will provide it.

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?


auto rotate screen Lenovo x380 yoga

I’ve installed these scripts to fix some issues on my Lenovo laptop (running Xubuntu 18.04).

When running the “status” commands under the Manual Installation section there seems to be a problem with the last part: For yoga-rotate@$ {USER}.service the output in my terminal is

● yoga--rotate@marco.service - [ThinkPad Yoga] Rotation with accelerometer        Loaded: loaded (/etc/systemd/system/yoga-rotate@.service; indirect; vendor preset: enabled)        Active: activating (auto-restart) (Result: exit-code) since Sat 2019-08-24 18:52:07 EDT; 4s ago       Process: 10067 ExecStart=/usr/bin/env python2 /opt/thinkpad-x380-yoga-scripts/rotate/thinkpad-rotate.py (code=exited, status=1/FAILURE)      Main PID: 10067 (code=exited, status=1/FAILURE) 

The solid dot at the beginning is grey, while for the other status commands they appear green. Not surprisingly, my screen does not rotate when I turn to tablet mode. Running the enable and start commands did not return any errors. At this point I don’t know what else to try.
