    Re: HOW TO: Compiling and Installing the OpenChrome Graphical VIA Driver

    Hello,

    I'm using a Packard Bell Easynote with S3 Unichrome Pro VGA Adapter.
    The script gave me 2D setup but no 3D.
    Is this correct?

I have installed fresh copy of new Ubuntu 7.10. The script ran well (did not ask for installation of 3D driver), and the xorg.conf file has changed to VIA driver etc., but then, after reboot, there was a mess with the colours and I had to do sudo dpkg-reconfigure -phigh xserver-xorg. Any ideas? Thanks in advance.

    EDIT: Never mind. It's now open SUSE on that laptop since the modem is not supported by Ubuntu, too.

    Re: HOW TO: Compiling and Installing the OpenChrome Graphical VIA Driver

    Hi there,

    Do you need to be connected to the internet for this script to work? I haven't set up my internet connection in Ubuntu as yet. Is it possible to do this without being online?

    Thanks

    Re: HOW TO: Compiling and Installing the OpenChrome Graphical VIA Driver

    I used both the script and Synaptic but suffered very poor window scrolling, freezing and just blank windows.. Arrrg
    I think I'm using VT8237

    I followed: http://ubuntuforums.org/showthread.p...+Unichrome+Pro

    The glitches have now gone but no 3D.... arrg

    now looking at:
    http://unichrome.sourceforge.net/

    Help!!!

    @Velenoso:
    Yes, you need to be connected to the internet to use either the script or to use Synaptic (the repo packages).

    @Tedd81:
    Please post the results of 'lspci' so that we can identify your chipset (certain chipsets work with 'trunk' others require the 'experimental branch' of the openchrome driver). Also, have you looked at the output of /var/log/Xorg.0.log for any X errors?

    Re: HOW TO: Compiling and Installing the OpenChrome Graphical VIA Driver

    There are no errors in Xorg.0.log but a couple of warnings i don't understand so i have attached it.

    Also:
    root@ted-laptop:~# glxinfo | grep rendering
    do_wait: drmWaitVBlank returned -1, IRQs don't seem to be working correctly.
    Try running with LIBGL_THROTTLE_REFRESH and LIBL_SYNC_REFRESH unset.
    direct rendering: Yes
    What do i do with this?
    (sorry a bit new to linux)

    Thanx for help, sorry for any silly questions!!!!!!!

    Re: HOW TO: Compiling and Installing the OpenChrome Graphical VIA Driver

    00:00.0 Host bridge: VIA Technologies, Inc. K8M800 Host Bridge
    The K8M800 northbridge is supported by both the Unichrome and Openchrome drivers. However, the Openchrome web site says of the K8M800:

    "2D acceleration should work just fine and 3D acceleration works fine as well, except on K8M/N800 chips where there are frequent hangs, probably due to timing problems"

    Hence, the 3D bug you experienced from running the Openchrome driver is known about (but not fixed). It's possibly the same bug that's showing up when you invoke 'glxinfo | grep rendering'. And there are no silly questions on the Ubuntu forums. We were all new to linux once.

    It would appear, that if you want 3D, your best bet is the Unichrome driver. You had the link in one of your previous posts. It contains some rudimentary instructions on how to compile it but before you do that, check the Gutsy repos to see if it's available as a package.

    To clarify what's going on: the openchrome video drivers (both 'trunk' and 'experimental_branch') produce a 2D driver which is only capable of 3D 'acceleration' ('direct rendering', 'hardware acceleration', or whatever name is your favourite) when using the unichrome_dri.so module. The unichrome_dri.so module is maintained by the unichrome project - a different project to the openchrome project. The unichrome project also has a 2D driver (commonly known as the unichrome driver). Therefore, BOTH the openchrome and unichrome 2D drivers rely on the unichrome 3D 'driver' to get direct rendering. As the openchrome project does not maintain the unichrome 3D driver (unichrome_dri.so) it has not fixed the problems your chipset (K8M800) is experiencing when you combine the openchrome 2D driver with the unichrome 3D driver. However, it would appear from the unichrome project's web site on sourceforge, that the unichrome 2D driver works well with the unichrome 3D driver for the chipsets the unichrome project supports - of which, the KM800 is one. Hence, it would appear your best bet is to try the Unichrome driver if you want stable 3D. Of course, the openchrome project's 2D drivers also enable 'accelerated' MPEG2 decoding on certain chipsets but the unichrome project does not. So, the choices for your chipset (K8M800) are one or the other (2D video + 3D video vs. 2D video + MPEG2 acceleration) but you can't have it all (2D video + 3D video + MPEG2 acceleration)

    Let us know if you require any further help.

    I uploaded a new version of the script, I tested it on a fresh installation and it works perfectly. Please try the script and any feedback is welcome.

    The script is on the first post of this topic!
