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?

Best regards,
								Pavel
