Hi!This is in -next, but I get same behaviour on 5.11; and no, udl doesThanks for reporting. We are in the process of fixing the issue. The latest patch is at [1].Thank you, that fixes the DMA issue, and I can use the udl. ...for a while. Then screensaver blanks laptop screen, udl screen blanks too. Upon hitting a key, internal screen shows up, udl does not. I try rerunning xrandr ... --auto, but could not recover it. Any ideas?
Seems unrelated. I tested for the issue with the last good revision and with the latest fix applied. I use Gnome/X11.
With both kernels, the udl adapter's display came back after suspending. So I'd attribute the problem to something else.
