Startx problems

[IPW]

so, this happened when i moved my pi into my room, and even when i put it where i first used it, it does the same thing.
it boots just fine, but when i try to run startx, it waits for a couple seconds, and then the screen goes dark, and then there are a bunch of commands on the screen, and it always says at the bottom

Code: Select all

xauth: (argv):1:  bad display name "(none):0" in "remove" command

I have no prior coding experience, i am not a computer wiz, and i humbly ask that solutions be in the most basic laymen's terms possible.

My model is a Pi 2B, and i have a usb keyboard and mouse, hdmi display, and i use an edimax wireless dongle, and ive also used an ethernet cable, but it still says the smae thing.

Thanks for any help!

When you moved the Pi, did you shut it down using the software commands, or just unplug it? You might have corrupted your card.

Before worrying about that, can you type the following at the prompt

Code: Select all

sudo cat /etc/hostname

and post the response here (that entry should return a name; if it is blank that could be the cause of the problem)

[IPW]

Well, i did the command, and it came up with

Code: Select all

sudo: unable to resolve host (none)
Cherry Pie

cherry Pie is what i named it when i got it. And i do believe i just unplugged. It might've been corrupted by that.

thanks for the reply!

The problem is that host names don't work well with a space in them. Also, best to stick to all lower case letters. Changing the hostname to have no spaces will fix the problem.

[Navyscourge]

Check this thread: viewtopic.php?f=36&t=49925

Firstly, a hostname cannot contain a space; the Pi gets confused because it 'thinks' the hostname is "Cherry" - it stops reading the name when it finds the space.

Use the raspi-config utility to change it to "Cherry-Pi" with a dash, not a space. If it still does not work, add the lines to the /etc/hosts file like in the thread above.

If you change the name using sudo raspi-config it reminds you of the syntax rules for host names. Not sure if it enforces them.

[IPW]

So, I changed it with Suso raspi config. Dud startx, then it said hostname: name or service not known.
Now the screen has gone black, and then it comes back on after a while and the screen shows that it was spamming protocol not found. Then it comes up with the same thing in the beginning, only instead of (none): 0 it says (cherrypie): 0.

Btw I changed it to cherrypie in raspi config

[DougieLawson]

That's because you've messed up /etc/hostname and /etc/hosts

/etc/hostname

Code: Select all

cherrypie

/etc/hosts

Code: Select all

127.0.0.1       localhost
::1             localhost ip6-localhost ip6-loopback
fe00::0         ip6-localnet
ff00::0         ip6-mcastprefix
ff02::1         ip6-allnodes
ff02::2         ip6-allrouters

127.0.1.1       cherrypie

[IPW]

It says

Code: Select all

/etc/hosts: permission denied

or

Code: Select all

/etc/hostname: permission denied

[AndyD]

It%20says%20

Code: Select all

/etc/hosts:%20permission%20denied

%20or%20

Code: Select all

/etc/hostname:%20permission%20denied

In the terminal. You will need to use an editor and sudo to raise you privilege.

Code: Select all

sudo nano /etc/hosts

Code: Select all

sudo nano /etc/hostname

[IPW]

i did that, but how do you get out of the terminal? is it X or ^X or what

[AndyD]

i did that, but how do you get out of the terminal? is it X or ^X or what

To write the file in nano ... hold down the [Ctrl] key and press the [O] (as in Orange) key.
To exit nano ... hold down the [Ctrl] key and press the [X] key.

[IPW]

So, i did everything you told me. I double checked everything, the hostname is now cherrypie, but now it does the same thing as mentioned before, only it says

Code: Select all

xinit: giving up

and

Code: Select all

xinit: server error

i dont know what i did wrong

[DougieLawson]

After you make those edits you MUST reboot.

[IPW]

Is there a specific command i use to reboot? i tried

Code: Select all

reboot

but it said that i must be superuser. or should i just unplug then plug back in? if i do that, im afraid i might corrupt it.

[DougieLawson]

sudo reboot # should work from the pi userid.

I think there's also an option on the GUI logout menu.

[IPW]

It... it still doesnt work... i have no clue what i did wrong! i did everything you guys told me... but i dont know what i messed up...

[QuietZone]

Wouldn't it be easier to just re-install (i.e., start over) at this point?

[IPW]

I honestly wouldnt know how to do that.

[DougieLawson]

I honestly wouldnt know how to do that.

If you SDCard is NOOBS/Raspbian then holding [SHIFT] during boot gets the recovery system running. You can use that to trash and re-install your system. YOU WILL LOSE EVERYTHING YOU'VE DONE unless you take a backup.
