    I've been attempting to resolve this issue for days, with no success. I'm fairly new to linux. I don't know anything about reinstalling the kernel (Although it sounds easy from what I've read). The window manager I'm currently using is KDE. I installed the nvidia drivers with pacman -S nvidia, then tried using startx. The screen goes black and my GPU fan comes on at full speed, then the laptop reboots after a few seconds. I also tried installing the proprietary drivers from NVIDIA's website with the same results. I've tried using nvidia-xconfig and bumblebee. The Xorg.0 log file has the entry
    Code:
    Screens found, but none have a valid configuration
    or something similar to that.


    I would have posted this on the Arch Linux forum but the verification is seemingly impossible in my state.

    You say laptop..so does this system have an Intel graphics card along with the Nvidia chip? If so the issue is Optimus which can very easily fixed.
    To find out:
    Code:
     lspci | grep -i --color 'VGA'
    P.S. Not trying to be mean or anything but if you are new to Linux you should try a more user friendly system. Ubuntu 14.04 LTS, Manjaro, Mint, a few others are easier for new users.

    The result is
    Code:
    VGA compatible controller: NVIDIA Corporation GK107M [GeForce GT 750M] (rev a1)

    Okay then. This is what I would do:
    1. reinstall the base Arch system.
    2. install KDE , nvidia, and (if 64bit) lib32-nvidia-libgl
    3. after all that is installed enable kdm
    Code:
    sudo systemctl enable kdm.service
    or without sudo if you are the root user
    4. reboot
    5. login via kdm.

    Again though, you may want to use a more user friendly system. :)

    I wiped the root partition, then used these commands:
    Code:
    pacstrap -i /mnt base (Reboot)
    pacman -S kde nvidia
    systemctl start kdm.service

    According to this post:
    https://bbs.archlinux.org/viewtopic.php?id=164747

    The issue may be the backlight being too low.

    What I would try is using the backlight keys to try and up the brightness. If that does not work take a look at this file:
    /sys/class/backlight/acpi_video0/brightness


    0 is lowest while 24 is highest.

    Also, is there anything in the journal

    Code:
    journalctl -b
    Code:
    dmesg 
    and the file ~/.xsession-errors


    and /var/log/Xorg.log

    Would you mind booting up an Ubuntu live cd? If Ubuntu loads the desktop, take a look at the
    'About this Computer' program in the top right menu. I still think your laptop has dual graphics.

    My laptop has SLI. I didn't think that mattered.
