(In reply to Adam Jackson from comment #2) > Please attach the output from lsusb with this dock connected. Ping? We need to know exactly which USB graphics device is in use here to be able to work on this. If, as I suspect, it's a DisplayLink device, then this is perhaps something of a known issue; Linux currently has no driver for USB 3.0 DisplayLink devices at all, and DisplayLink refuses to provide the necessary programming information to enable them.
Adam: Thank you for your response. Neither 1) Lenovo Display Link, Thinkpad USB 3.0 Dock P/N 03X6059, or 2) Lenovo Thinkpad Mini Dock Plus Series 3 P/N 433830U work with a Lenovo Thinkpad T430 and RH Linux. Nothing seems to work for enabling up to three monitors. One internal laptop screen, and two external monitor screens like Microsoft Windows with extending the desktop screen display mode. Linux also will not boot if NVIDIA graphics card is enabled Linux only works to leave set on Intel HD Graphics adapter. Also disappointed that even running MS Windows KVM in RH it does not allow Windows to see or use the External Monitors as Hardware or USB 3.0 docking stations. Really wanted to move to RH platform to replace Windows 7.x, but RH does not appear to support additional display devices and as a Enterprise customer we continue to wait and wait. Contact me via e-mail if Lenovo vendor is not providing information needed and I will knock on some doors for you. Respectfully.
Lincoln, we don't have any of those would you be able to test once fixed package is ready or can you provide a link where we can buy one of those? Thanks Tom
Just to update DisplayLink has still not given us any indication of support for these devices on Linux. So Red Hat cannot support them.
