xorg: startx fails

[wynnmc]

I have installed xorg according to the Xorg/Guide and it failed to start. I have tried to capture the output of startx but it didn't work, I have copied the (only) error message in it by hand:

Code: Select all

(EE) parse_vt_settings: cannot open /dev/tty0 (permission denied)

It says that it can't open the module "intel" -- in VIDEO_CARDS I have set both intel and i915 and from "lspci -k", the module in use is i915.

I hope someone will see what is wrong.

wynnmc,

Code: Select all

[ 16857.868] (EE) parse_vt_settings: Cannot open /dev/tty0 (Permission denied) 

You need one of systemd, elogind or to build xorg-server with USE=suid.
USE=suid is considered a bad thing and must not be set system wide.

You may well have elogind installed already. Is it started?

[wynnmc]

That's it! Thank you, Neddy ... don't go away, I'm going to install Xcfe4 now ...

Thanks a lot, wynnmc

[Banana]

If you have choosen to use openrc instad of systemd, have a look here:

[wynnmc]

Thank you, Banana, I'm installing Xfce from the instructions on the page you mention.
I've now looked at the elogind page and I see that there are some things to do when xfce is installed. Somehow, on this machine, elogind just seems to work -- I remember the changeover some time ago but I don't remember having to make any configuration changes .. perhaps I've just forgotten.
