Display not detected on Ubuntu 14.04.3

eyalb181 · 02-14-2016, 01:45 PM

Hello,

I'm trying to connect a Phillips 233v to my Lenovo Y50 laptop, but it's not being detected.
I'm running Ubuntu 14.04.3, kernel version is 3.19.0-49-generic
I've attached DisplayLinkManager.log and dmesg (is there anything else that could be helpful?)

Any help would be appreciated, thanks!

Hi eyalb181,

There are USB connection errors in the logs you provided. To rule out unreliable HW could you please check different USB cable with your USB adapter? Preferably a cable you already trust, it can even be a USB 2.0 one.

Cheers,
Szymon

Thanks for your reply. Unfortunately the USB cable can't be replaced (we're using this adapter). However, we did manage to get it working on a different machine, which as far as I can tell is similar except in kernel version (3.16). We've tried using all USB ports but none of them work. Is there anything else we could try?

Thanks,
Eyal

Thanks for the reply Szymon. Unfortunately the cable can't be disconnected from the adapter. We've actually tried the same adapter on a different machine (same laptop model, same Ubuntu version and all) and it worked. Is there anything else that could help figure out what the problem is?

rcouto · 02-19-2016, 11:33 AM

News: I kind of managed to get it to work again. When I plugged my Dell D3100 in a USB 2.0 port, it all started to work again. I suspect that before updating Ubuntu, my kernel thought that every port on my notebook (Dell Inspiron 13 7348) were USB 2.0. Now the two ports on the left side are being detected as USB 3.0. But, of course, this situation is suboptimal. Under load, my display is laggy and sometimes the image quality decays. I think this is the works of some kind of compression algorithm compensating the lack of bandwidth of the USB 2.0 connection. Anyone got it to work in a USB 3.0 port?

eyalb181 · 02-22-2016, 08:17 AM

I tried again with a working adapter, and it still doesn't work, so we can rule out HW. What else?
