Hello Everyone,


I have successfully installed Fedora 24 with onto a RPI3 with Kraxel's kit. I also installed X and tried to set the default state of the machine to graphical.target using systemd. I also have xrdp installed. I can easily and successfully RDP across to the machine and use LXDE.


When I try to use it at the machine itself, there is not X environment firing up. I have the following errors in dmesg:

My config.txt looks as follows:


arm_freq=1200
core_freq=400
sdram_freq=500
over_voltage=6
gpu_mem=256
max_usb_current=1
arm_control=0x200

# NOOBS Auto-generated Settings
hdmi_force_hotplug=1
config_hdmi_boost=4
overscan_left=24
overscan_right=24
overscan_top=16
overscan_bottom=16
disable_overscan=0

# workaround firmware issue for rpi3
# u-boot doesn't work without this
enable_uart=1

Would anybody have any thoughts on solving this issue. I know it may not be completely a Fedora problem especially since its not a Fedora team built kernel. But would still appreciate the help. Thanks/


Cheers,


ASD.
