Hi guys,

I have the AOC E1649FWU. It is a USB 2.0 displaylink device.

It works fine in Linux. But I am unable to rotate it via xrandr.

The screen goes blank when I attempt to rotate left or right. I am
able to fix the screen by rotating normal. However when I attempt to
rotate again I get the following error:

[sunny at localhost ~]$ xrandr --output DVI-1-0 --right-of eDP1 --rotate
normal --mode 1366x768_72.00 --rotate left
X Error of failed request:  BadValue (integer parameter out of range
for operation)
  Major opcode of failed request:  139 (RANDR)
  Minor opcode of failed request:  7 (RRSetScreenSize)
  Value in failed request:  0x0
  Serial number of failed request:  48
  Current serial number in output stream:  49

I am on Fedora 21 with kernel version 3.17.8-300.fc21.x86_64 and X.org
version: (1.16.3 RC 1)

The following are links to info people may consider useful in debugging this:
