I recently upgraded to devuan excalibur from Daedalus and afterwards chinese input in 'scim' with xfce DE doesn't work properly, during the upgrade, I appended ' ~/.xsessionrc ' to make sound work in 'piperwire' as pulse audio was broken,  but afterwards scim doesn't allow me to see onscreen display of chinese characters as typed using 'pinyin' method.

what i have in '/home/erdos/.xsessionrc'     

LANG=en_US.UTF-8
export LANG
XMODIFIERS="@im=SCIM"
export XMODIFIERS
GTK_IM_MODULE="scim"
export GTK_IM_MODULE
scim -d&
wireplumber &
pipewire &
pipewire-pulse &

any advice?
