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
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: 184.108.40.2061 (1.16.3 RC 1)
