    Occasional low-graphics mode after failed Macbuntu install

    I have a dell-inspiron n5110 and I just upgraded to Ubuntu 12.10, I tried to install Macbuntu 10.10, previously I had gnome-fallback installed. The installation didn't completely work or seemed to be done, I logged out and back on and all was fine, and I uninstalled Macbuntu. Now occasionally I can log on perfectly ubuntu with full graphics (with an occasional system problem detected), but just as often, sometimes after having the successful login screen, I am forced into low-graphics mode, can't use mouse or anything, and am told I'll have to configure the graphics.

    I would like to know how to fix this problem so that I no longer am forced into low-graphics mode ever. This is kind of urgent, I appreciate any help.

    What graphics drivers are you using? Is there maybe anything left from MacBuntu 10.10, which is, as far as I know, not designed to be run on 12.10?

    I am experiencing the exact same thing on my Dell Inspirion 5110 and Ubuntu 12.10. Please advise, have you found a solution to this problem already.

    Thank you

    Same problem here. Ubuntu 12.10 ThinkPad T420 without NVidia optimus, i.e. only Intel HD graphics.

    In Xorg.log I see

    Code:
    [     4.852] (II) VESA: driver for VESA chipsets: vesa
    [     4.852] (II) modesetting: Driver for Modesetting Kernel Drivers: kms
    [     4.852] (II) FBDEV: driver for framebuffer: fbdev
    [     4.852] (++) using VT number 7
    
    [     4.852] (II) intel(0): using device path '/dev/dri/card0'
    [     4.852] (WW) Falling back to old probe method for vesa
    [     4.852] (WW) Falling back to old probe method for modesetting
    [     4.852] (WW) Falling back to old probe method for fbdev
    [     4.852] (II) Loading sub module "fbdevhw"
    [     4.852] (II) LoadModule: "fbdevhw"
    [     4.852] (II) Loading /usr/lib/xorg/modules/libfbdevhw.so
    [     4.852] (II) Module fbdevhw: vendor="X.Org Foundation"
    [     4.852] 	compiled for 1.13.0, module version = 0.0.2
    [     4.852] 	ABI class: X.Org Video Driver, version 13.0
    [     4.907] (EE) intel(0): [drm] Failed to open DRM device for pci:0000:00:02.0: No such file or directory
    [     4.907] (EE) intel(0): Failed to become DRM master.
    [     4.908] (II) UnloadModule: "intel"
    [     4.908] (EE) Screen(s) found, but none have a usable configuration.
    Then in Xorg.failsafe.log I see:
    Code:
    5.613] (EE) FBDEV(0): FBIOPUTCMAP: Invalid argument

    Re: Occasional low-graphics mode after failed Macbuntu install

    Hmm, there's another thread about this problem: http://ubuntuforums.org/showthread.php?t=2073483

    it seems like the solution might be:

    Code:
    sudo apt-get install gdm
    or if you already have gdm installed:

    Code:
    sudo dpkg-reconfigure gdm
