Xorg and Ubuntu Issues

lucaschettini — Tue, 11 Apr 2017 09:26:50 GMT

Goodmorning,

we have a custom board, iMX6Q and iMX6D based.
I've followed the Ubuntu guide (Installing Ubuntu Rootfs on NXP i.MX6 boards ) and with some trouble, add the GPU-IPU and X11 GPU acceleration, but now I can't start LXDE with startx.

What's wrong?

TY and have a nice day.
Luca

Info: Ubuntu Xenial 16.04.02 - Custom Kernel 3.14.54 - X.org 1.18.4

Hi,

What's the output of this command?

ps -ef | grep x

Try to kill next processes in this order: lxdm-binary, xldm, Xvfb

and run now: startxfce4 -- vt7&

xorg.conf file has the vivante details included, something similar with:

# nano /etc/X11/xorg.conf
Section "Device"
Identifier "i.MX Accelerated Framebuffer Device"
Driver "vivante"

Hi thanks for reply,

Marius Grigoras:
Hi,

What's the output of this command?
ps -ef | grep x

This is the ps output:

root@inventami:~# ps -ef | grep x
root 158 2 0 12:31 ? 00:00:00 [irq/81-imx_ther]
root 162 2 0 12:31 ? 00:00:00 [ext4-rsv-conver]
root 698 1 0 12:32 tty1 00:00:00 /sbin/agetty --noclear tty1 linux
root 700 1 0 12:32 ttymxc1 00:00:00 /bin/login --
root 735 700 0 12:32 ttymxc1 00:00:00 -bash
root 1142 831 0 16:51 pts/0 00:00:00 grep --color=auto x
root@inventami:~#

Try to kill next processes in this order: lxdm-binary, xldm, Xvfb
and run now: startxfce4 -- vt7&

xorg.conf file has the vivante details included, something similar with:

According to the first post, xorg.conf is identical like your code, and when I launch LXDE I've that output:

root@inventami:~# startlxde -- vt7&
[1] 1143
root@inventami:~# Agent pid 1145
** Message: main.vala:99: Session is LXDE

Please try to assign DISPLAY prior starting X-server. I mean something like this:

# export DISPLAY=:0
# startx
