    Re: Low graphics mode

    I do not know why it does not happen with HDMI (maybe some completely independant phenomena). With DVI it does exactly like you all.

    Another issue I am encountering which might be related (since it involves xorg) : my keyboard and mouse (logitech wireless) are lagging very badly (even though the computer works fine and quickly).

    All a mystery, so far! I have no issues once I'm into Unity. Very fast main box, notice my signature.

    Very good... maybe someone will fix it, one way or another. I added by comment to the bug report.

    Re: Low graphics mode

    I decided to install gdm and select it instead of lightdm and all is okay now.

    It's an issue with parsing the video card and lightdm. This can be fixed by the developers if attention is given to it.

    Try it and see, but first use Software Center to install gdm, then:

    Code:
    sudo dpkg-reconfigure gdm
    Make the selection to gdm and reboot. The login screen is back to the old themes but the OS boots normally to the desktop.

    Let us know how this goes for you. Thanks!

    I'm having the exact same issue as the OP and others. I'll try the lightdm workaround. It's a workable workaround for me if it works: it saves me a lot of battery power.

    I can confirm, that gdm-lightdm workaround works very well for me.

    Re: Low graphics mode

    After carefully reading this bug report I've found a solution, that works for me. I've added the following code into /etc/rc.local script

    Code:
    sleep 1 && service lightdm restart
    Don't forget check the script is executable. Good luck!

    Doesn't work for me, but I see that the devs are working on it. For me it goes back to 12.04.

    Re: Low graphics mode

    This fixed it for me across two machines. Software sourcees is screwed on both (this is a messy ubuntu upgrade and no mistake) so use comad line

    or use a 3rd-party repository created by Tomasz Makarewicz for this purpose only. (I personally recommend it)

    sudo add-apt-repository ppa:makson96/fglrx
    sudo apt-get update
    sudo apt-get upgrade
    sudo apt-get install fglrx-legacy

    see http://www.unixmen.com/ubuntu-12-10-...roblem-solved/

    let me know

    Paul
