I have a 12inch 2880x1920 monitor (eDP-1) and a 21inch (eDP-1) with a 1920x1080 native res. I tried to use

xrandr --fb 6720x2160 --output DVI-I-2-2 --mode 1920x1080 --right-of eDP-1 --scale 2x2 --panning 3840x2160+2880+0

and I got:

X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 29 (RRSetPanning)
Serial number of failed request: 46
Current serial number in output stream: 46

I have an Asus t303ua
with:
VGA compatible controller: Intel Corporation HD Graphics 520 (rev 07) (prog-if 00 [VGA controller])

Is there a plan to support panning in the future on Linux?

I am a video deejay using a Macbook that has a failed GPU so i currently rely on one of your devices to connect to an external display.I upgraded to Mac OS High sierra and realized that my display link driver works differently(blue airplay icon) and i have much better performance now(faster frame rates with mix-emergency & Serato ,transparency on the dock And task bar),thank you for that .But The problem is Mac Os High Sierra is Just too Unstable right now for example due to the failed GPU i have completely disabled it but because of that my laptop does not sleep when l close the lid also when it sleeps it cannot wake the screen when i wake it up also i cannot control the screen brightness worst of all i have experienced 3 complete unrecoverable Os crushes in the past two weeks since finally upgrading to high sierra from mac OS sierra so i`ve reinstalled mac OS sierra and my computer works just fine now but im back to the older functioning display link driver that has better resolution on my external display running natively in 1360*768 resolution but has much much lower frame rates on both mix emergency and virtual DJ video output because it doesn't work like the air play one on high sierra .

so my suggestion is that you please implement the same airplay idea on high sierra it works much better

my current display link hardware is a USB 2.0 to dvi ,hdmi and vga (USB 2.0 UGA 17)

I'm running MacOS 10.13.3 (downgraded from 10.13.4 for reasons that I'm sure you know) on a MacBook Air (13-Inch Mid 2011, 1.8Ghz Core i7, 4 GB RAM) and whenever I have any of your latest (e.g. most recent final releases, two most recent "Betas" to fix the issue with MacOS 10.13.4) it causes Ableton Live 10 (10.0.1) to not load/run.

The main reason that my computer system and I have a DisplayLink in my environment is for making music. I use the two screen setup while working with Live to have my AU and VST plugins visible while tracking. Without this software in place my second display is essentially a paperweight.

It'd be great if you could test later releases with Live 10 so this is actually usable for me.

I've verified that it's the DisplayLink software by installing and uninstalling the software and being able to successful replicate the problem as expected.

Please let me know if you would like any logs.

Try this

1- shut down your MB
2 - unplug both adapters
3- restart MB
4- after it's up and you've logged in first plug in the the display port adapter and wait for the monitor to come online it should be an extension, not mirror of the MB monitor
5-plug in the USB adapter and it should mirror the MB display, though at a lower resolutions than the other external monitor.
6- DO NOT CLOSE THE MB. If you do it will create a mirror to both monitors if you do

While the MB comes up okay when the screen slips, it will not come back after closing the laptop and put it into sleep mode.

So you have to shutdown and restart your MB everytime you go to plug the adapters back in.

Not a perfect fix, but the best I've been able obtain
