Thanks shado for the 'dirty hack'
BTW, I am having a weird problem. Once I start an lxc-container, gdm instances uses the entire resources of both of the processor.
How can I disable gdm and start x directly. I tried with a solution here (
http://www.fprimex.com/linux/slackware/ ... ay-manager) but does not look like working. I tried to use CDM (
http://cdm.ghost1227.com/X11), but even after specifying the binaries in (/etc/rc.d/rc.4) and commented the x4 line in the /etc/inittab, it does not present at init 4 boot (followed
https://wiki.archlinux.org/index.php/CDM).
Simply I do not want to start gdm or start in runlevel 3 and then use a command to enter xserver (like startx with a tiling wm like i3) as a user. Could anyone throw some light on this? Thanks!
UPDATE: It does not seem gdm problem, because even when I run x without GDM and start a container, htop shows that the following process uses 100% of the CPU resources and 5.7% of Memory:
/usr/bin/X :0 -nolisten tcp -dpi 96 vt7 -auth /home/user/.serverauth.2452
Any input appreciated. Thanks!
(PS: In the same machine in the debian installation, it only took me 5 minutes to install, configure and run lxc

and with slack/Salix I am struggling for the last four days! hmmmmm)
