In April 2017 I bought a Thinkpad E470 with the intentation to install Linux, more specific my prefered distribution Debian on the testing branch Stretch which will get stable in a few weeks. I’ll give a short overview of things that are working and things I have problems with, followed by a more detailed explanation of what I did.
- Graphics (Intel & Nvidia)
- Sound (Onboard, External)
- External Monitor
- Partly Working
- Not Working
- Untested / Unknown
- SD-Card Reader
- Hardware Disk Encryption (TCG Opal)

I’ve installed Debian from the netinstall usb image. Graphical installation was working, necessary hardware (LAN) detected fine. The system was set up as a minimal installation on an software encrypted disk with lvm. After finishing the installation and rebooting into the installed system, I’ve modified the /etc/apt/sources.list and added non-free repos
deb http://ftp.de.debian.org/debian/ stretch main contrib non-free deb-src http://ftp.de.debian.org/debian/ stretch main contrib non-free deb http://ftp.de.debian.org/debian/ stretch-updates main contrib non-free deb-src http://ftp.de.debian.org/debian/ stretch-updates main contrib non-free deb http://ftp.de.debian.org/debian/ stretch-backports main contrib non-free deb-src http://ftp.de.debian.org/debian/ stretch-backports main contrib non-free deb http://security.debian.org/debian-security stretch/updates main contrib non-free deb-src http://security.debian.org/debian-security stretch/updates main contrib non-free
and updates the package list.
dpkg –add-architecture i386 apt-get update
LAN was working, but the device was giving error messages. WLAN wasn’t working. To fix those problems (and possible others), I’ve installed a basic selection of firmware packages:
apt-get install firmware-linux firmware-linux-nonfree firmware-realtek firmware-atheros
After another reboot the error message were gone and WLAN was working, too.
Graphical installation and configuration
The Thinkpad E470 uses the Nvidia Optimus technologie, using the Intel onboard card for normal work and the Nvidia card for visually more demanding software. Since the release of the Optimus technologie, the open source counterpart bumblebee made great progress. I’m using the propritary nvidia driver (available from the non-free debian repo) with Primus (the sucessor to VirtualGL). This part is based on a wiki page on the Debian wiki. After installing the packages and adding the user to the respective group
apt-get install bumblebee-nvidia primus primus-libs:i386
adduser $USER bumblebee
application can be started with:
I’ve testing this with glxgeras, Factorio and Kerbal Space Program (via Steam), all three working fine. To make Steam games use the Nvidia card, change the launch options to ‘‘primusrun %command%’’. If a game won’t start, maybe the old VirtualGL is working better. To use it, the program has to be started via:
I wasn’t able to run Dota 2 or Euro Truck Simulator 2 with neither of the comamnds, this post will be updates if a solution was found.
I’ve bought a HDMI to VGA connector to use my old monitor (as the E470 doesn’t have a VGA port), but the Thinkpad sometimes can’t find the monitor. After plugging it out and in again it’s working most times, reason unknown. Maybe a hardware problem with the connector.
Another most likely hardware related problem occurs in combination with the USB hub my mouse and keyboard are plugged in to. If the hub is connected to the THinkpad during the start, it won’t boot. The screen keeps just black. After unplugging the hub, the BIOS screen comes up and grub is starting. Without plugging it in everything is fine, too. I think I have to contant Lenovo about this.
So far most things are working fine, all my requirements and expectations were met. The device is working great with (Debian) Linux and can be recommended to any looking for a cheap but modern entry level Thinkpad with good Linux support.
