Thank you very much 林果皞 But when I want to ` cat ~/home/m/.xinitrc` it says: cat: /root/home/m/.xinitrc: No such file or directory and when I want to ` cat ~/.config/openbox/autostart ` it says cat: /root/.config/openbox/autostart: No such file or directory

@user145959 create that files if not exist. The answer above, I assume you logged in as m (non-root) user when perform the tasks. /root/home/m/ is incorrect since ~ is your current user. This is my typo to replace your username, I will update my answer.

@user145959 You shouldn't logged-in as root user when create that files, otherwise the files owner will become root instead of home user.

I tried with m user but got same result

@user145959 I assume your username is m , what's the output when run echo ~ ?

Should I do everything from the first with m user again?

echo ~ says /home/m

@user145959 I assume your non-root user is m, since you don't mentioned the real non-root username in your question.

@user145959 Then do vi ~/.xinitrc to write the content.

Yes I have 2 user. one is root and other is m. But m user has not sudo access: m is not in the sudoers file. This incident will be reported.

@user145959 su -> type your root password -> adduser m sudo (ref: unix.stackexchange.com/a/179961/64403). Don't forget exit current bash session from root to perform your task.

I built it for /home/m/.xinitrc but for /home/m/.config/openbox/autostart it says : ".config/openbox/autostart" E212: Can't open file for writing when I want to save it

Can I put in inside /etc/xdg/openbox/autostart instead of /home/m/.config/openbox/autostart

@user145959 better don't, since you want your gui session run as non-root. What's the output of ls -la /home/m/.config/openbox OR ls -la /home/m/.config ? Isn't that folders exist ? Can you cd /home/m/.config/openbox ?

@user145959 You should run vi /home/m/.config/openbox/autostart, not vi .config/openbox/autostart. What command do you run to edit your file ?

ls -la /home/m/.config/openbox ls: cannot access '/home/m/.config/openbox': No such file or directory

ls -la /home/m/.config total 12 drwx------ 3 m m 4096 Nov 19 16:18 . drwxr-xr-x 8 m m 4096 Nov 23 14:59 .. drwx------ 2 m m 4096 Nov 19 16:18 pulse

@user145959 mkdir /home/m/.config; cp -R /etc/xdg/openbox /home/m/.config/ , read this

It didn't work :(

I have only a blank screen

@user145959 That's the purpose of the /tmp/log_file, is that files exist after reboot ? Also you can direct test by login with m in other vt (i.e Ctrl+Alt+F[1|2|3|4|5...], I wonder you know this before), and /home/m/.profile will be executed if loggedin. Change 1 in ` "$XDG_VTNR" -eq 1` to your tty number to test without reboot. Did systemctl get-default changed to multi-user.target ? Also don't forget to revert back what you've done before follow my instruction. (e.g. the rc.local and systemd file you've edited). I have no problem to pop up the img in Ubuntu 17.04. (not server version)

How to check /tmp/log_file is exist or not? Ctrl+Alt+F[1|2|3|4|5...] don't work! I think keyboard don't work at all(I use SSH). How can I find my tty number? when I ran systemctl list-dependencies multi-user.target | grep getty I got same result as what you put and I think my tty number is 1 too. and about last question, yes, it is changed to multi-user.target

I found a difference, this is my content: # /etc/systemd/system/getty@tty1.service.d/10-noclear.conf [Service] TTYVTDisallocate=no# /etc/systemd/system/getty@tty1.service.d/override.conf [Service] ExecStart= ExecStart=-/sbin/agetty --autologin m %I $TERM

sorry, I really wasted your time a lot

You see I do > /tmp/hole1, > /tmp/test1, > /tmp/yy, right ? Check that files created or not by listing the files in directory /tmp/, i.e. ls -la /tmp/

cat /home/m/.xinitrc ?

Also, is /usr/bin/env bash working ? (Ctrl+D after run without error)

/usr/bin/env bash

May you explain more?

i did copy /usr/bin/env bash but had no result

run /usr/bin/env bash

is there any error ?

no nothing happens

ok, just Ctrl+D to exit after run.

ok i did it

and wrote exit

that's means exec startx -- -nocursor has problem, since it doesn't run ~/.xinitrc

is your startx file same as this pastebin.com/8fQEuAt2 ?

Maybe i damaged it before by doing that?

you can do unlink ~/.xsession , in my ubuntu, I'm not even has ~/.xsession symlink.

I don't know how to unlink it! unfortunately I only do what other user suggest :(

sorry, my typo, I means cat <you result from type >

e.g. type -a startx return me the path /usr/bin/startx, then you need to do cat /usr/bin/startx

unlink ~/.xsession

unlink is a command.

unlink: cannot unlink '/home/m/.xsession': No such file or directory

I believe it's /root/.xsession since you are loggein as root previously.

what's your output of "type -a startx" ?

-bash: -a: command not found

sorry

"type" is a command.

"cat /usr/bin/startx" ?

compare with the pastebin.com/8fQEuAt2

vimx is vi in your system.

then edit to remove the "#!/usr/bin/env bash " in /home/m/.xinitrc.

when I run sudo vimx /etc/default/grub

it opens an empty file

And edit the "exec startx -- -nocursor" to "startx" in ~/.profile

sudo vi /etc/default/grub

opens an empty file

sudo cp /usr/share/grub/default/grub /etc/default/

ref: askubuntu.com/questions/406229/…

cp: cannot stat '/usr/share/grub/default/grub': No such file or directory

never mind, forget about it.

I use Ubuntu server and only installed openbox

then edit to remove the "#!/usr/bin/env bash " in /home/m/.xinitrc. ....I did it

The reason I want you to edit is because it will shows log indicated it's still running instead of splash screen when boot up, So you will not think it hang.

edit the "exec startx -- -nocursor" to "startx" in ~/.profile, done ? reboot it to see.

wait, one more thing

nvm, just reboot after edit startx

only blank screen

"ls -la /tmp/" still same ? No/tmp/test1 ?

there is no test1 file inside /temp folder

Maybe problem relates to this?

change startx to "startx > /tmp/my.log 2>&1"

then reboot again to see the log.

cat /tmp/my.log after reboot.

try this: "sudo apt-get purge nvidia-"

sudo apt-get purge nvidia-*

* asterisk at the end

ref: ubuntuforums.org/showthread.php?t=2205149

E: Unable to locate package nvidia

ok removed it

also try "Xorg -configure"

ref: forums.freebsd.org/threads/50004

I think the problem is finding my SPI LCD

it uses fbtft framebuffer kernel support to work

github.com/notro/fbtft/wiki

Change your startx to "FRAMEBUFFER=/dev/fb1 startx > /tmp/my.log 2>&1"

Also, ls -la /usr/share/X11/xorg.conf.d/

Also "cat /home/m/.local/share/xorg/Xorg.0.log"

should I reboot and do it after reboot?

is ok, just do it after reboot

you changed to FRAMEBUFFE=/dev/fb1 already ?

yes

but I think I should change to fb8

cause my LCD works only with fb8

then try fb8 also

And "cat /etc/X11/Xwrapper.config"

ref: unix.stackexchange.com/questions/149985/…

changing to fb8 had no result

again blank screen

cat /home/m/.local/share/xorg/Xorg.0.log ?

It starts openbox very easy when I put "startx" inside "/etc/rc.local"

but I don't know why it can't recognize my lcd now

What you put in rc.local ? "cat /etc/rc.local" ?

I say when I put startx , it can find my LCD

but now it can't

it was strange for me why now it gives [ 25.411] (EE) No devices detected.

if you put it back and do "sudo systemctl set-default graphical.target" , you can see your screen again.

Why now I can't?

I mean why with multi-user it doesn't work

did you tried put startx back to rc.local and reboot ?

no

i will do it now

and don't change back to "graphical.target" now to test.

ok

it works...it shows the openbox gray screen with mouse pointer

I didn't change to graphical.target and only put startx inside rc.local and it worked

what's the output of "ls -la /dev/fb*" ?

how did you test to know it only works by fb8 ?

you put it in rc.local ?

no before I make .conf files I tested them manually

fb8 only could run my LCD

it mostlikely is because of permission issue, since ~/.profile run startx as non-root user , but /etc/rc.local run starts as root.

this thread: unix.stackexchange.com/questions/149985/…

since your log also shows "(EE) open /dev/fb8: Permission denied "

So should I make a .conf file?

where should I build that? with what name?

what content?

see askubuntu.com/questions/924993/…

sudo usermod -a -G audio m
sudo usermod -a -G video m

add m user to video group.

then remove the startx at rc.local, and retry

reboot

If still failed after reboot, try dpkg-reconfigure xserver-xorg-legacy and /etc/X11/Xwrapper.config steps mentioned at the thread.

worked!!!!!!!!!!!!!!1

adding m to audio and video groups worked

Thamk youuuuuuuuuuu

but your answer had many steps...may you final edit it? and I can use your answer for future

again thank you.....I don't know how to say

if I could I gave you 100+ points

I'm glad I was able to help, cheers :)
