Hi guys, I have the AOC E1649FWU. It is a USB 2.0 displaylink device. http://us.aoc.com/monitor_displays/e1649fwu
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@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: 1.16.2.901 (1.16.3 RC 1) The following are links to info people may consider useful in debugging this: EDID information: https://gist.github.com/intsunny/cc6e1341e68fb9fb0a51 xrandr commands used to config screen: https://gist.github.com/intsunny/10bac695e0533fcc73f8 dmesg info of screen: https://gist.github.com/intsunny/2d0b503ca2e8fbb87311 Xorg.0.log output: https://gist.github.com/intsunny/6333714651b777adeb7b _______________________________________________ [email protected]: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.x.org/mailman/listinfo/xorg Your subscription address: %(user_address)s
