manually install DE on server release. something maybe wrong?

I should install desktop release on my H3 (OPI PC), not server.

after WIKI search,

apt-get install xfce4 libmali-sunxi-r3p0 lightdm libvdpau-sunxi1 xorg xserver-xorg-video-fbturbo mpv

some other apt-get not listed.

I get XFCE runs on H3. and get video hwdec enabled.

and some modify on asound.conf get HDMI audio works.

/etc/asound.conf

pcm.!default {
    type hw
    card 1
}

ctl.!default {
    type hw           
    card 1
}

with continue dig, I find I need to modify boot.cmd 

enable memory reservations to make it better.

so the boot.cmd:

setenv bootargs "console=ttyS0,115200 console=tty1 root=/dev/mmcblk0p1 rootwait rootfstype=ext4 cgroup_enable=memory swapaccount=1 panic=10 consoleblank=0 enforcing=0 loglevel=${verbosity}"
 

and build new boot image by:

mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr

but, I can still find some errors in X.org.log

[    27.083] (II) FBTURBO(0): using backing store heuristics
[    27.091] (II) FBTURBO(0): can't load 'g2d_23' kernel module

and kernel message:

[   27.091653] [DISP] disp_ioctl,line:1584:para err in disp_ioctl, cmd = 0x0,screen id = 65536

and when I check kernel config, i find these two modules (g2d_23, sunxi_cedar_mod) are builtin.

its there anything wrong?
