I have been using my FW13 AMD Ubuntu 22.04 LTS successfully with a 27" external monitor past few days. Today I plugged it into a 34" Samsung G5 ultrawide via the HDMI and the monitor does not receive any signal. The monitor works with another Windows laptop.
I searched the forums but didn’t find this exact issue.
I filed a support ticket but thought I’d see if anyone had encountered and resolved already.
Any insight, thanks!
I had the same issue until I tried another port for the HDMI output. Mine is not working on the rear left USB4 port. I did not have time to fill a support ticket though, just letting you know to try yourself.
Thanks @Aurelien_D, the rear left port did indeed work for me. Seems like both the front ports don’t work for HDMI.
The official documentation for the 13 AMD is here:
So your HDMI output should at least work on the front right one. You should ask support about it.
Damn, I didn’t notice that that port is known not to support HDMI. Thanks for pointing that out.
This is correct. I’ll mark this as resolved.
I found this trick always makes the external display work with my laptop: simply unplug the HDMI expansion card and plug it back in.
Unplugging the HDMI cable does not help. In fact, I leave the HDMI cable plugged into the expansion card when I do this. I flip the laptop over, hold the button to release the expansion card, and slide my HDMI expansion card out and back in. It works every time.
I have a Framework with a 12th gen intel core running Ubuntu 22.04. I bring this laptop back and forth from work, so I run into this on a daily basis when I plug in the external display at work and at home. Sometimes both displays work, but usually I only get one display (sometimes it’s my laptop, sometimes it’s the external display). Hot plugging the HDMI expansion card triggers the laptop to do something that fixes the problem.
