A: How to change autologin from root to non-root user?

You told me in other comment that your system shows this: $ systemctl get-default graphical.target So, change it to multi-user.target: $ sudo systemctl set-default multi-user.target And multi-user.target will start at tty1 (Ctrl+Alt+F1): $ systemctl list-dependencies multi-user.target | gr...

user145959

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

林果皞

@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.

user145959

I tried with m user but got same result

林果皞

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

user145959

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

echo ~ says /home/m

林果皞

16:29

@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.

user145959

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.

林果皞

@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.

user145959

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

林果皞

@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 ?

user145959

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

林果皞

16:29

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

user145959

It didn't work :(

I have only a blank screen

林果皞

@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)

user145959

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/[email protected]/10-noclear.conf [Service] TTYVTDisallocate=no# /etc/systemd/system/[email protected]/override.conf [Service] ExecStart= ExecStart=-/sbin/agetty --autologin m %I $TERM

sorry, I really wasted your time a lot

林果皞

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/

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

/usr/bin/env bash

user145959

May you explain more?

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

林果皞

run /usr/bin/env bash

is there any error ?

user145959

no nothing happens

林果皞

16:40

ok, just Ctrl+D to exit after run.

user145959

ok i did it

and wrote exit

林果皞

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

$ type -a startx
startx is /usr/bin/startx
startx is /usr/bin/startx

$ cat /usr/bin/startxtype

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

user145959

Did you read this part of my question?

Then I tried to create ~/.xinitrc file with this content:

#!/usr/bin/env bash
/home/m/img &
exec openbox-session

Then made it executable by this command: chmod +x ~/.xinitrc

But I got nothing(even it didn't show my openbox after reboot), So I executed this command too:

ln -s ~/.xinitrc ~/.xsession

Maybe i damaged it before by doing that?

-a startx
-bash: -a: command not found

林果皞

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

user145959

cat /usr/bin/startxtype
cat: /usr/bin/startxtype: No such file or directory

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

林果皞

16:50

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.

user145959

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

when I type " startx -a " it says "-bash: -a: command not found
"

林果皞

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

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

user145959

-bash: -a: command not found

sorry

林果皞

"type" is a command.

user145959

startx is /usr/bin/startx
-bash: type: -a: not found

林果皞

16:55

"cat /usr/bin/startx" ?

compare with the pastebin.com/8fQEuAt2

user145959

#!/bin/sh

# This is just a sample implementation of a slightly less primitive

Can you do this way:
"sudo vimx /etc/default/grub"

edit the "quiet splash" to "text"

then do "sudo update-grub"

vimx is vi in your system.

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

user145959

when I run sudo vimx /etc/default/grub

it opens an empty file

林果皞

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

user145959

sudo vi /etc/default/grub

opens an empty file

林果皞

17:04

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

ref: askubuntu.com/questions/406229/…

user145959

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

林果皞

never mind, forget about it.

user145959

I use Ubuntu server and only installed openbox

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

林果皞

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

user145959

only blank screen

林果皞

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

then reboot again to see the log.

cat /tmp/my.log after reboot.

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

林果皞

18:25

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

user145959

nothing
exit 0

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.

林果皞

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

user145959

Why now I can't?

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

林果皞

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

user145959

no

i will do it now

林果皞

18:31

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

user145959

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

林果皞

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

user145959

But I know this command only works by fb8 (I tested it before)

Add to file /etc/modprobe.d/fbtft.conf

options fbtft_device custom name=fb_ili9341 gpios=reset:1,dc:201,led:6 speed=16000000 rotate=90 bgr=1

林果皞

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

user145959

Sorry, I meant this command:

FRAMEBUFFER=/dev/fb8 startx

林果皞

18:38

you put it in rc.local ?

user145959

no before I make .conf files I tested them manually

fb8 only could run my LCD

林果皞

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 "

user145959

So should I make a .conf file?

where should I build that? with what name?

what content?

unfortunately it says:

man Xorg.wrap
man: can't set the locale; make sure $LC_* and $LANG are correct
No manual entry for Xorg.wrap

林果皞

18:58

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.

if still failed, `cat /home/m/.local/share/xorg/Xorg.0.log` to see error fb8 permission denied message still there or not.
if not there, post the new log here.
If still there, you may better ask a question with that info OR try to install Ubuntu Desktop 17.

user145959

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

林果皞
