    Re: Anyone got MIR working in raring?

    This developer would be able to add CalDAV support for sure:

    https://syncevolution.org/

    Because i do imagine this is quite big task. For e-mail (back-end) app Yorba could be approached?

    Re: Anyone got MIR working in raring?

    When all this things fall into place we will get Ubuntu DE i guess. At least on mobile.

    Could some of the work from Sailfish OS be used? At least at the beginning to boost things up and then make in-house solutions if it makes sense but i think it would make more sense to start pushing devices and attracting 3rd party devs and to work on Mir in the beginning for example because it will take a lot of effort!

    Edit: The PPA now works in Raring and the Touch Core Apps install. Which is progress. But they do not load. Pity. I would think that as these are the core apps of the Ubuntu touch devices and MIR is being developed as the display driver specifically for those Touch devices, then getting them running under MIR is the aim. I tried replacing a mir_demo name with a core app name but nothing happened except a blank screen. Still, we are on our way. Not going very fast, I admit. At least the development has been opened up to anyone who is a bit curious.
    I think we are more or less getting framework files at this point, but, the mir server does work. I think it is just the command line sturcture that we have to wait for (or keep experimenting with). Watch,wait and experiment. If I come up with anything I'll post it here first.

    Still no word from Voss. His email box is probably crammed with bug reports.

    EDIT:

    18MB more of mir-doc files in updates.

    I was presented with this 2 days ago but I am trying to focus on what I can do with MIR first and I had to give myself a refresh course in X and terminal commands.

    I may even try it.

    so we can adjust the variables to get different results.

    More to come.

    Edit:

    If you want to examine all of the files for demo_examples then go to:

    /usr/share/doc/libmirclient-demos/examples

    You can open and examine them. They are written in C or C++. If you have any basic programming skill they are easily understood and rather simple subroutines.


    I am going to try to switch some variables a little later on and see what results I get. The moving image that we get comes from the data in the file mir_image.h and or graphics.h data.

    Any ideas on a good compiler to make this executable? I have to replace mir_demo_client_accelerated executable with the new script compiled into executable format.

    Run Midnight Commander in Mir

    I think I cracked the demo code.

    If you want you can try this code to run Midnight Commander on the MIR server.
    First you have to have MC installed.

    Code:
    sudo apt-get install mc
    After having all of you MIR files updated from the ppa run the code below on a terminal (CTRL+ALT+F1)

    Code:
    (sleep 200; mir) & mc ; kill $!
    The 200 represents 200 seconds that Midnight Commander will run *MC* on the mir server**. It will be fully functional but seems to terminate after the alotted time frame. To quit Midnight Commander just hit F10 then <yes> . Mir will exit normally. If it goes past timeframe it will terminate and you will need reboot CTRL+ALT+DEL.


    This test took place on a PC with these graphics card parameters:

    Code:
     *-display
                 description: VGA compatible controller
                 product: 82915G/GV/910GL Integrated Graphics Controller

                 physical id: 2
                 bus info: pci@0000:00:02.0

                 capabilities: vga_controller bus_master cap_list rom

    and will try on Nvidia and ATi also.
