I have a problem with startx and non root users,
every reboot, before be able to startx from users, I have to startx with root...after that I can startx with others users too without problems.
what can be?

I'm on gentoo linux, xfce, my .xinitrc

thanks in advance

Something in the long chain needs permissions 4755, or 4711. I forget which permissions, and what exactly, but an elementary bit of searching should akkow you to sort yourself out. I learned that on LQ. You can too, by searching the forums.

There should be a file in the user's /home directory. It should not have been copied from another user's directory and should be created the first time X is run as that user, not root.

thanks but I already tried to delete it but still doesn't works

If you do a long listing on that file, I bet you'll find that it belongs to root and not to you. Use sudo to delete it. Then try to log in again as yourself.

No, it belong to me, not root.

Maybe I didn't explain me well, but I can startx with my user but only once doing a startx with root.

I have to
1. Boot the computer
2. Startx with root (and exit)
3. Startx with my user

So it works, not if I skip 2.

The error if I skip 2. is that device is found but there is no configuration available (tomorrow I can quote the exapt error)

If that is your .xinitrc file it is wrong. .xinitrc is a shell script and should have have the shebang at the top, No spaces. ( for some reason even with the code tags its not coming out right).

Another idea to look at is logind. Based on your description it doesn't sound like you're using it.
From https://wiki.gentoo.org/wiki/Xorg/Guide#Configuration"
Note
By default the suid USE flag is disabled, which is fine when, as per recommendation, X runs under a logind provider like elogind, or systemd. The suid USE flag should however be enabled in /etc/portage/package.use/xorg-server in case no logind provider is used and X is run under a normal user account, e.g. started with startx. Please see also this repository news article. Setting suid would then prevent permission errors on /dev/tty0, or on virtual console 7.

That's odd. What do you get when issuing the command:

Over here there's some information about rootless xorg. Have you tried what's listed here?

I found the problem. I wrong put the flag "user" in /etc/fstab on the root partition.
Very bad mistake

Thanks to all

And this was causing the root partition to be unmounted somehow? Am I understanding that right? Sorry, just seeking clarification for future reference.

I cannot su with the "user" flag on the root and for some reason I cannot startx too, solved the su problem X is starting corrrectly
