    Hi Guys,

    I am using Android on my UDOO Quad. I connected a 1280 x 1024 monitor but I can't get the resolution higher than 640 x 480. I tried to set the resolution manually and also the DPI via an app and in the command line. The DPI will make the proportions right but the screen resolution will stay low.

    This all happened after I updated to Android 4.4.2.

    I hope someone can help?

    Cheers,
    Thom

    I am not a Android on UDOO user. But could you please test what happens on the UDOObuntu release. Are there any higher resolutions possible or not?

    Due to the fact they use the same Linux version as a base this may be the same issues like in UDOOBuntu. This is why I asked if you could test with UDOOBuntu

    Dear folks,
    we've released UDOObuntu 2 RC2. Could you tell us if you get HDMI issues with RC2 too?

    I am testing for 2 days and i really loved it. But there is a problem, my windows moves laggy, mouse movements nice but when i click something and drag, it freeze. I opened task manager and looked what does this but nothing eats high cpu; when moving windows in the desktop with mouse, the max cpu is being %26. What should i do?
    Regards

    Edit: I used top command to see all cpu eating processes. from Root XORG is eating %99.9 cpu when moving a window.


    What is the username and password?
    Could you explain how can i run the QT5 on udoo board? Yocto looks nice but, i am poor about os knowledge. I only know win32diskimager, putting image from .img file to sd card and use it :/
    Usually, well-knowledged people miss how can noobies do. About installing some overview steps introduced and we get problems.

    Yocto is a highly configurable combination of build system and reference distribution (poky). There is a own thread on the forum with details how to get started. But you shouldn't be scared of Linux command line :)

    @his I know it sounds super-weird, but we're aware that moving windows does heavily consume CPU resources, it's a known bug. We think is maybe driver-related. What you think guys? Does someone have a clue about this?

    Sir,
    I do not know well about these things, i found some topics. Maybe it is not related with our board or OS. Sorry but may give some clues about kernel bugs.
