My project need to rotate screen.
I use Yocto git://git.freescale.com/imx/fsl-arm-yocto-bsp.git -b imx-4.1.15-1.0.0_ga release version with Wayland backend and Qt5.
What is best way to rotate 90 degree clock-wise ?
I try to use weston.init (I add my self) with my display is LVDS 1024x768.
but, that is not work. in this reason
I try name=WL1, but it was not work too.
I see manual, if I use name=LVDS1, I must use drm or x11 backend.
So, I add [core] section with backend option like as
but, If I use this option, I fail to loading dri/swrast_dri.so, dri/vivante_dri.so.
how can I install this library with Waland backend Yocto build system?
or, is there any better way to rotate screen without this way?
Finally I got it working.
The problem was in wrong connector name in the weston.ini.
root@imx8mmevk:~# ls /sys/class/drm/
card0 card0-DSI-1 version
I was trying to use card0 and card0-DSI-1 as a KMS connector names in the weston.ini. Then I took a look at /var/log/weston.log and found that proper name is DSI-1.
[05:55:41.223] DRM: head 'DSI-1' found, connector 33 is connected, EDID make 'unknown', model 'unknown', serial 'unknown'
[05:55:41.223] Registered plugin API 'weston_drm_output_api_v1' of size 24
[05:55:41.224] Chosen EGL config details:
RGBA bits: 8 8 8 0
swap interval range: 1 - 60
[05:55:41.224] No backlight control for output 'DSI-1'
[05:55:41.224] Output DSI-1 (crtc 31) video modes:
email@example.com, preferred, current, 67.3 MHz
[05:55:41.224] associating input device event0 with output DSI-1 (none by udev)
[05:55:41.224] associating input device event1 with output DSI-1 (none by udev)
[05:55:41.224] associating input device event2 with output DSI-1 (none by udev)
[05:55:41.224] Output 'DSI-1' enabled with head(s) DSI-1
So 'card0' part of name should be omitted.
Rotation works properly for me with following weston.ini:
root@imx8mmevk:~# cat /etc/xdg/weston/weston.ini
# i.MX: Disable idle timeout
command=/usr/bin/weston --backend=rdp-backend.so --shell=fullscreen-shell.so --no-clients-resize
I found the device name at "/var/log/weston.log".
And I add these lines to "/etc/xdg/weston/weston.ini" :
(My default screen size :1024x768 and 60Hz)
You can set "transform" 90 or 270 to use your display vertical.
Thanks for your reply.
Frankly speaking, I know the way to use XRandR, but when I use x11 backend, the Qt application have window border on the top.
But, I do not want border. I want full screen with my own Qt application without any X11 window border.
may I know I can I remove it?
