Stefan, awesome, thanks for this. Rotation works fine on my Intel HD4000.
I have reduced your xorg config to this:
Code:
Section "Device"
Identifier "intel"
Option "kmsdev" "/dev/dri/card0"
Option "PageFlip" "off"
EndSection
Section "Device"
Identifier "USB3"
BusID "USB"
Driver "modesetting"
Option "kmsdev" "/dev/dri/card1"
Option "PageFlip" "off"
EndSection
I'm also using the new driver - and glxgears seems synced with the DisplayLink monitor's refresh rate. However for it to draw properly I had to use:
compton --glx-use-copysubbuffermesa --glx-no-rebind-pixmap
(I'm using compton with openbox)
My only complain is CPU usage. With glxgears running I get 40% usage on one core... is this normal?
taiki - try removing the RandRRotation and rotate options. It rotates fine for me without those.
