    First Car PC, Gentoo Attempt..

    Just wanted to stop in and say hello. I've been considering doing a car pc for a while now, and finally started the project.

    The car:
    2004 350z Touring model. Bose w/o Navigation. The plan is to use the 2003 cubby, with a 7" touch screen.

    The hardware:
    Athlon XP x64 5600+(2.9ghz dual)
    1-4 Gig Ram(have 4 gigs..)
    250 SATA laptop drive
    USB GPS - prolific chipset


    OS:
    Gentoo Stage 3 Install(Well maybe).
    genkernel kernal
    Fluxbox and/or Slim window/desktop manager?
    Pandora Radio via Adobe Air
    Navit -- Maybe, kinda working
    python interface/mp3 player/weather -- Using pymedia's module

    I use SLES and ubuntu on a daily basis. I -thought- I had become decent at linux. Gentoo is, well, a humbling experience.

    The gentoo install was pretty easy, and the more I used portage the more I liked it. However, I couldn't get X to work right on my first install. I emerged, xorg-server, xdm, fluxbox and slim. If I rebooted, it would come up and go to a black screen, and X working pretty hard for several minutes. After 5-10 minutes randomly i'd get a login screen. I added fluxbox to my xinitrc, and specified fluxbox as my XSESSION parameter in rc.conf. I also put slim in my xdm.conf . Fluxbox wouldn't start automatically, I finally fixed that by adding fluxbox to slim.conf (I think?). However, I still have a long delay before X starts, and it seems to randomly die..even tho 'X' is still running.

    Looking in my xorg.log I saw 'unknown module' radeon, which made me think my ati drivers were incorrect and causing the long delays in X loading, and slow performance. However, if I tried to install ati-drivers, I got an error saying >=xorg-server-1.7.0 was blocking ati drivers ? I couldn't get past this.

    Things I did manage to get working:
    pymedia module for python
    navit -- I had to manually touch the usb device for my prolific /dev/ttyUSB0
    Pandora --- I use Pandora currently on my iphone connected to my radio. I love it, and this is part of my plan for my car PC. After installing adobe air, and grabbing the pandora.air this worked very well.



    My first attempt was on an old spare IDE drive, i've decided to start fresh with the drive i'll be using. I'm not looking to be spoon fed, but i've exhausted my googling abilities and can not figure out my issue with my ATI Radeon onboard video. It's an Radeon 3200 series onboard video. I thought maybe it was a make.conf issue, so I added video card = Radeon to it, and re-emerged xorg, xdm, flux, and slim. I've been tempted to just install gnome or kde and see if that fixes it, but that seems like alot of bloat that I don't need for this project.


    I've learned alot this weekend playing with Gentoo, but it's been pretty painful... USE Flags are something else..

    My -goal- is to write my own interface in python. I'd like to integrate weather information on the main screen, have Music, GPS and Web abilities. I plan to call a 3rd party app for GPS(Navit or something). For Music, i'll write an mp3 player in python to handle this(pymedia module). As well launch Pandora.. I don't think I need a full blown gnome/kde environment to do this, but having a 5-10 minute delay in X starting is unacceptable.

    have you looked at linuxICE yet? Even if you plan on writing your own interface, LinuxICE already has a slim boot and the window manager down. It may save you some work.

    Actually I have, and very impressed with it.

    I originally picked gentoo since I was considering using a Wyse v90, with a Via Nehemiah CPU. I thought Gentoo be a solid lean OS to use for this.

    After deciding to go with the ahtlon, I thought gentoo be a good challenge and learning experience.

    I actually got X working properly last night. xdm and fluxbox.

    I am going to install nghost and see how it works, I started on the install last night. I woke up to an error on the libnghost, something about config.c or configure.c was expected. I'll work on it tonight, I noticed the wiki said it was 'unfinished', but that was the only gentoo instructions I found.

    I really like ubuntu, it's my environment I use at work. However, gentoo has grown on me. Really enjoyed portage, and the more I learn the more I like it.

    Assuming I can get nghost running, there is a good chance i'll end up using that. Which is part of the linuxice project if I understand correct? Most users tend to use ubuntu as the base though?

    There are a few developers/users that use gentoo + nghost. But yeah, most people i think either use LinuxICE or use Ubuntu + nghost.

    the latest svn of libnghost is still in development. If you want a stable version check out revision 2024 of libnghost/nghost, which is the latest stable in LinuxICE as well.

    I will try that tonight, Not sure which version I have been trying.

    I tried following the wiki, and using the two ebuilds. libnghost fails everytime on aclocal. aclocal.out says it needs either configure.h or configure.in. I couldn't find any information about that and an libnghost install. I am using automake-1.11, so I tried installing version 1.10.. Same issue.

    I then tried using the ubuntu tar's, ./configure, make and make install. libnghost installed without an issue, though it did fail to find phono, hdradio, gui3, sample, and another plugin.. but finished normally. Afterwards I had a nscan-cmd and nghost-cmd in my /usr/local/bin directories. If I try to ./configure nghost it fails saying nghostcore isn't present. I don't know if perhaps my pkg_config_path is incorrect, do you know where it's checking for nghostcore?

    I actually created an account on your forum and was going to post this question there. do you think I'll have better help there? Still waiting on my authentication e-mail hah..

    I searched your forum, and google, and the only information i found regarding gentoo and nghost is the small section on the wiki that says 'not complete'. I'd like to become more involved in the gentoo side of this project, as the more I look at nghost the more I like it. I think my time would be better spent on nghost then doing it 'my own way'.

    Thanks Kev

    Kev, stupid question. But where do I find revision 2024? The only one I found is 2087?

    I have installed nghost on my gentoo based carputer a few times, and every time tripzero [FKA Kev000] has been a great help, i'm too lazy to do it now but i believe if you search at either MP3car or the linuxice forums you might find some of the trip ups i had that tripzero helped me through. also the IRC channel was good, and if you decide to go with NavIT for your gps solution their IRC channel was VERY helpful when i was trying to understand how it worked.

    I like portage as well, glad to see yet another gentoo user on the forums.

    Actually when I searched the forums, I found alot of your post because of your signature=) I considered sending you a PM a few times, since you are one of the few I saw advertising gentoo + nghost.

    Work + Girl cuts into my time quite a bit, I haven't spent very much time in the evenings on it this week. I plan to put in another geek weekend of sitting on my couch playing with gentoo. My goal is to get nghost installed.

    I'll do some more searching, but I am actually still waiting on my activation e-mail for linuxice forums. I've re-requested it a few times, it's not made it to my inbox, spam or any other filter. Kinda odd.

    Can you point me in the right direction, were you able to use an ebuild or did you have to compile it from source? That way i'll quit wasting my time with one of the two=)

    You've been activated on the linuxice forum. for some reason smtp isn't working.

    You'll need to checkout that revision from svn:

    see: http://wiki.openice.org/index.php?ti...Ghost#From_svn

    just add a '-r' to the command:

    Code:
    svn checkout -r2024 [url]

    Awesome thanks Kev. Grabbing svn was actually the first time I had ever used the svn command.. I didn't even think to check the manual to see if that's how you selected revisions. I was expecting a completely different URL.

    I will try this tonight, Hopefully that has been my issue. I assume 2087 is not considered stable?

    Thank you for activating me on the forums.

    Hopefully I can stop nagging, and start contributing soon.
