    For those of you with bluetooth problems, see this thread:

    http://ubuntuforums.org/showthread.p...1#post10612268

    You need updated drivers. I got mine working.

    So, bluetooth is up and running.
    Ok, I got it to work, not very gracefully, but it works. Forcing evdev to touchscreen mode was the key, i couldn't find a nice way to do this though, so i downloaded the evdev source code v2.5.0 and just disabled the touchpad interface, and forced it to touchscreen. Here is what I changed in evdev.c
    Klick0, can you post the link from where you downloaded the evdev source?

    Thanks,
    Victor

    You can download the evdev driver from:

    ftp://xorg.mirrors.pair.com/individu...v-2.5.0.tar.gz

    I just realized, evdev 2.6.0 is out, the mirror I used before only had upto 2.5.0. You may just want to try 2.6.0.

    I'm gonna see if 2.6.0 detects the device as a touchscreen, if it does, then problem solved. If not, you could still probably use 2.6.0 if you wanted, and just make the same/similiar change as above.

    Ubuntu 11.04 beta just came out, has some multi-touch support with their new interface. I think i'm gonna load that up to see how it works.

    How does 11.04 handle this hardware? Does touch and bluetooth work out of the box?

    I tried to install 11.04 alpha on the slate but it messed up my grub so I didn't even test it.

    I was running 11.04 alpha on my desktop and ran into similar bluetooth issues - not sure if the updated bluez made it to the repos but would imagine it has. I'm going to give it a try later as well.

    I'll try it out once I receive the Slate (the slate is Temporarily not available here in France).

    So, what about accelerated graphics? Can you play HD videos smoothly?

    That's good news, but I try to avoid using Windows as much as possible ; I don't feel like home using this Operating System.

    Win7 is more shiny than the previous release, but nowadays, we can really do a lot with Linux :

    • Synfig
    • Inkscape
    • Mypaint
    • The Gimp (really need a new UI)
    • Blender
    • Openshot
    • Scribes


    Gosh! If everything work on the Asus slate it might be a dream come true.

    I agree with you but since I haven't been able to get multi-touch working on the slate, I've relied on Win7 but intend to ditch it as soon as I get ubuntu working!!

    Actually, ok it adds it, touching the screen make it move to the lower right, i dunno, i don't even see it.

    Hi Klick0,

    what do you mean exactly when you say you tried evtouch? I went to synaptics to download xserver-xorg-input-evtouch, but i don't get the output "EVTouch TouchScreen id=15 [slave pointer (2)]" when I type xinput list. I tried the next steps you suggested, but they didn't work, so I think i did osmething wrong when installing evtouch drivers.

    I'd like to use your solution to get touchscreen working, even if it doesn't have multi touch.

    Thanks

    ~Paolo
