Hi:
Does ls1028ardb support 4K resolution? When the 4K resolution is set, it is found that the Weston desktop is not displayed. The steps are as follows:
1.vi /etc/xdg/weston/weston.ini:
idle-time=0
#use-g2d=1
#xwayland=true
gbm-format=argb8888
[libinput]
#touchscreen_calibrator=true
[output]
name=DP-1
mode=3840x2160@60
force-on=true
#transform=90
[shell]
size=3840x2160
2.Then set the Weston display:
root@LS1028ARDB:~# mkdir -p /run/user/0/
root@LS1028ARDB:~# export XDG_RUNTIME_DIR="/run/user/0/"
root@LS1028ARDB:~# weston --tty=1 &
3.check the mode
root@LS1028ARDB:~# weston-info
