    Exclamation Dell E6420 video problem.

    Hello everybody.

    I want to explain what happened to my laptop Dell e6420 with Ubuntu 32bit 12.04 (3.2.0.32 kernel).

    Last week my laptop frozen in two different days without any type of error and it was been necessary to reboot through the power-on button.
    Ok, I thought that there were some problems with the new kernel and the video drivers.
    It's ok, go ahead.
    I did a backup with Remastersys (god bless the authors) and when I reboot the laptop, unity worked at 2D mode.

    Code:
    echo $DESKTOP_SESSION
    ubuntu-2d
    Code:
    /usr/lib/nux/unity_support_test -p
    OpenGL vendor string:   VMware, Inc.
    OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 0x300)
    OpenGL version string:  2.1 Mesa 8.0.4
    
    Not software rendered:    no
    Not blacklisted:          yes
    GLX fbconfig:             yes
    GLX texture from pixmap:  yes
    GL npot or rect textures: yes
    GL vertex program:        yes
    GL fragment program:      yes
    GL vertex buffer object:  yes
    GL framebuffer object:    yes
    GL version is 1.4+:       yes
    
    Unity 3D supported:       no
    What???
    I thought that It was a problem with virtualbox (VMWARE), no way....I purge it, I followed all guides to re-install mesa, intel and any type of proprietary drivers (nvidia included)...but at the end there was not been a solution to return back to unity 3D!!!
    In the purge and reinstall steps, something went wrong and my ubuntu is died

    Well, I decided to re-install it with the remastersys backup. At the boot I noticed that also the live-cd runned to 2D (so it was an old problem, before the backup).
    I installed the backup and in the update manager I selected the precise-proposed updates.
    In the repository there was the 3.2.0.33 version of the kernel, I installed and unity has returned back to 3D

    Code:
    echo $DESKTOP_SESSION
    ubuntu
    Code:
    /usr/lib/nux/unity_support_test -p
    OpenGL vendor string:   Tungsten Graphics, Inc
    OpenGL renderer string: Mesa DRI Intel(R) Sandybridge Mobile x86/MMX/SSE2
    OpenGL version string:  3.0 Mesa 8.0.4
    
    Not software rendered:    yes
    Not blacklisted:          yes
    GLX fbconfig:             yes
    GLX texture from pixmap:  yes
    GL npot or rect textures: yes
    GL vertex program:        yes
    GL fragment program:      yes
    GL vertex buffer object:  yes
    GL framebuffer object:    yes
    GL version is 1.4+:       yes
    
    Unity 3D supported:       yes
    Great!!! But It has worked for only 3 days until the compat wireless driver installation.
    In fact, this morning I installed the driver for the first time, I uninstalled them and finally I re-installed them....at the second reboot, unity has returned to work in 2D mode!!!

    At the end...I reinstalled (for the second time) the remastersys backup.

    What does it happened?
    How can I solve this problem for the next times?
    Now I am scared to install and do anything!!

    Thank you very much for the help!

    Have a nice day!
    Bye.

    Hi!

    I got exactly the same problem of unity working in 2D after installing a 2012-10-30 release of compat-wireless. My computer is a Dell Inspiron 14z. Apparently it's quite a new problem having issues with video after installing compat-wireless since I couldn't find anything really from the forums.

    Dell E6400, E6410 and E6420

    I duplicated the issue on all three laptops.

    Not sure if it's a bug, but I submitted a report anyway.
