[opensuse-support] Tumbleweed - unable to connect Apple Thunderbolt Display to Lenovo Thinkpad P52
Hi, I am having problems with connecting my laptop to an Apple Thunderbolt Display [1]. The P52 has two Thunderbolt over USB-C ports and I am connecting it to the Apple Display using an Apple adapter. A colleague has validated that the display works with a Macbook using a similar adapter. I am using the 'Discrete Graphics' setting and using the proprietary nvidia driver version 410.93. I have checked the following: - in the BIOS Thunderbolt assist is disabled ( should not be necessary _and_ it is reported to brick the laptop [2] ) - in the BIOS I have set the security level to 'none' - in Gnome the 'Thunderbolt' panel displays 'Thunderbolt could not be detected' - xrandr -q does not return any connected displays $ xrandr -q Screen 0: minimum 8 x 8, current 3840 x 2160, maximum 32767 x 32767 DP-0 disconnected (normal left inverted right x axis y axis) DP-1 disconnected (normal left inverted right x axis y axis) HDMI-0 disconnected (normal left inverted right x axis y axis) DP-2 connected primary 3840x2160+0+0 (normal left inverted right x axis y axis) 344mm x 193mm 3840x2160 60.00*+ DP-3 disconnected (normal left inverted right x axis y axis) DP-4 disconnected (normal left inverted right x axis y axis) - tbtadm devices returns no entries.

2 suggestions: one fairly easy, one less so. #1 I have an Apple 27" Thunderbolt display on my Retina iMac. I have to use a separate external Thunderbolt cable, *not* the built-in one. The built-in captive cable works, but then the auxiliary ports on the back of the screen do not and both adaptive brightness control and direct control via System Preferences fail. So, try a different cable. #2 I know it's not very helpful, but I'd try with a different OS, e.g. Windows. I have failed to get my device working with another non-Apple computer, and Googling for why suggested it probably won't work with anything else. -- Liam Proven - Technical Writer, SUSE Linux s.r.o.

You can't remove it, you shouldn't try and you don't have to. You buy a Thunderbolt cable and you plug one end of it into your laptop -- via adaptor if required -- and the other end of it into one of the the Thunderbolt ports on the back of the monitor. I have coiled up the Apple cable and tied it with a cable-tie, so that it doesn't get in the way. (Incidentally I have also removed the Apple stand, and mounted the T'bolt display on one of these: https://www.amazon.de/gp/product/B00U8KSWB6 I recommend it. It's strong, includes the special Apple mounting bracket in the box, and makes the screen far more versatile. Mine is now a large portrait display and works very well in this mode. I found 2 × 27" landscape screens side-by-side was impractical and gave me neck-ache.)
Ah. That is unfortunate. I usually keep it around, disk space permitting, for things like hardware testing, firmware updates, and in order to facilitate dual-booting on UEFI machines. -- Liam Proven - Technical Writer, SUSE Linux s.r.o.

You can attach it to a Macbook Pro via the built-in cable, then attach other Thunderbold peripherals, including daisychaining more Thunderbolt displays, to the monitor... Or, you can attach the monitor to a computer via a Thunderbolt cable, and then use the other ports (Thunderbolt, Ethernet, USB, Firewire) from that computer. E.g. my Retina iMac doesn't have onboard Firewire, but I can use the port on the Thunderbolt display and it works fine. So long as I'm using an add-on cable and not the built-in one. The only thing is that they're quite expensive -- circa €30-€40. -- Liam Proven - Technical Writer, SUSE Linux s.r.o.
