A new patch to disable Huawei chipsets in udev rules.
First, the udev rules was placed in wrong place. /usr/lib/udev/rules.d/
can't be read, we need push it into /lib/udev/rules.d/.
/usr/lib/udev/rules.d/61-gdm.rules => /lib/udev/rules.d/61-gdm.rules
Second, the rules need change the running time directory from /run/gdm
to /run/gdm3.
# disable Wayland on Hi1710 chipsets
ATTR{vendor}=="0x19e5", ATTR{device}=="0x1711", RUN+="/bin/sh -c '/bin/mkdir
/run/gdm3 ; /usr/bin/printf \"[daemon]\nWaylandEnable=false\" >>
/run/gdm3/custom.conf'"
