despit the fact that my previous posts were a little bit pessimist, I did continue to try installing GhostBSD. It didn't work well and continue to freeze each time.
Then, I 've download FreeBSD 10.2 and install it with Mate desktop, and everything was done successfuly. after what I delete once again the partition, create an usb stick with the amd64 version of GhostBSD "dd if=./Ghostbsd-10.1-mate of=/dev/sdb bs=64k conv=sync" under Debian PointLinux ( my other desktop distrib).
after boot, the system is frozen , as described in previous posts ( Christophe , me ... ) . after a few minute , I was enabled to disabled the sleeping status in the power management , and after open a terminal, stop things that I don't need (vbox ) . then after some freezes again , I was enable to config and connect the wifi. putting the system in french was easy but took time because of some freesing states again, then I clicked on the install icon.
after setting up name,root pass, locales etc. , the installation took about 9 hours, I had to awake sometime the laptop ( Dell vostro 1500 , Intel core i2. 1,4 ghz and 2 go mem.) to allow the install to continue.
I'm very, very proud and happy to post this description from my new Ghostbsd desktop. Everything seems to work well , no freeze at all, nevertheless the boot takes some times, more than Freebsd 10.2, even after modify the boot sequence ( disable beastie and so on ).
Curiously , after using bsdconfig to update console locale, user's group and thing's like that, and after adding fr to gdm_lang to rc.conf, GDM still in english.
Mate Desktop is localized in french , means every dialog box or terminal are in french , keyboard layout is ok , but application's menu and desktop's menu are in english.
here is my rc.conf :
# See /etc/defaults/rc.conf to add more option.
# Do not configure /etc/defaults/rc.conf.
# Configure only this file.
# Power saver.
powerd_flags="-a adp -b adp"
# DEVFS rules
# Enable linux compactibility
# Virtual Box adition configuration
#Netork card configuration by Networkmgr
Eric, thank you for your work and your implication in this great distrib , and in this forum.
Don't give up , the light is ahead.
Juste un dernier mot, pour dire que la vie et la liberté sont fragiles, c'est aussi pour cela qu'elles sont si précieuses.
