Problem with my new machine

[Van_Vinkle]

I've bought a new desktop computer and installed in it two Linux distros: MX and Salix.

The installation of both was fine. MX gives a dual boot option. For three o four days all was OK, but today (and without any change of which I was aware) Salix started a weird behavior. At the first screen, when the system asks for the user and password, I give them and instead of start the system, this screen appears again, asking for user and password again and again.

I tried to fix through a boot repair disk, but no luck. However, it yielded me a lot of information which I can give you if you want.

Check that you are not out of space in salix partition.

[Van_Vinkle]

This is not the case. Being a new computer, it has an enormous space in disk: for Salix, the partition containing "/" has 99% of free space, and for "home," it has 86%. No more partitions for Salix.

Are you using the same /home for both distributions?

[Van_Vinkle]

Are you using the same /home for both distributions?

No, other folder in another partition.

Hit Ctrl-Alt-F1 (or F2-F4) and try to login in a console. What happens?

[Van_Vinkle]

Crtl + Alt + F1 gives console.
Here I can enter by user + password.
Then I order startx.
Console answers:

Code: Select all

xauth: error in locking authority file /home/lluis/.serverauth.1450
         error in locking authority file /home/lluis/.Xauthority

The last line is repeated four o five times.

I would check that all files and directories in /home/lluis belong to the user lluis, as they should.

More info:

I did backup of /home on my old machine.
Could I copy some files from there to the new /home?

After logging in run the following commands:

Code: Select all

id
ls -lA
ls -l /home

What do you get?
