Just remove the nvidia driver (and linux-headers-generic just for the heck of it), install linux-headers-`uname -r` first, then reinstall nvidia. Everything should work fine.

    First, make sure nvidiabl is being loaded automatically by adding a line saying simply "nvidiabl" to /etc/modules.

    The scripts I posted above weren't quite right, but they were really close. Here's what they should be:
    /etc/acpi/nvidia_backlight_up.sh:
    Code:
    #!/bin/sh
    
    test -f /sys/class/backlight/nvidia_backlight/brightness || exit 0
    
    VAL=`cat /sys/class/backlight/nvidia_backlight/actual_brightness`
    MAX=`cat /sys/class/backlight/nvidia_backlight/max_brightness`
    STEP=10
    
    VAL=`expr $VAL + $STEP`
    
    if [ $VAL -gt $MAX ]; then
    	VAL=$MAX
    fi
    
    echo -n $VAL > /sys/class/backlight/nvidia_backlight/brightness
    /etc/acpi/nvidia_backlight_down.sh:
    Code:
    #!/bin/sh
    
    test -f /sys/class/backlight/nvidia_backlight/brightness || exit 0
    
    VAL=`cat /sys/class/backlight/nvidia_backlight/actual_brightness`
    MIN=0
    STEP=10
    
    VAL=`expr $VAL - $STEP`
    
    if [ $VAL -lt $MIN ]; then
    	VAL=$MIN
    fi
    
    echo -n $VAL > /sys/class/backlight/nvidia_backlight/brightness
    /etc/acpi/events/nvidia-brightness-down:
    Code:
    event=video LCD 00000087 00000000
    action=/etc/acpi/nvidia_backlight_down.sh
    /etc/acpi/events/nvidia-brightness-up:
    Code:
    event=video LCD 00000086 00000000
    action=/etc/acpi/nvidia_backlight_up.sh
    Then you have to make sure those scripts are executable:
    Code:
    sudo chmod +x /etc/acpi/nvidia_backlight_up.sh
    sudo chmod +x /etc/acpi/nvidia_backlight_down.sh
    You also need to have permissions to edit the brightness file itself (this was one of the problems I ran into -- the keys were running the script, but I didn't have permission to change the file so nothing happened). I'm not sure if this is the "proper" way to do things, but it at least works. Someone can correct me if I'm wrong and I'll edit this post:
    Code:
    sudo chown YOURUSERNAME /sys/class/backlight/nvidia_backlight/brightness
    That should work for a Lenovo Y500. It's not quite a perfect workaround -- the brightness actually increases and decreases slightly past what the indicator shows, but it basically works and I think you'll be quite happy with it.

    If it works for you exactly as I've written it up, please report back. If there was anything I didn't quite explain or that didn't quite work, please report back so I can edit this post for others as well.
    Thanks for posting in detail.... The graphical brightness indicator seems to have a fixed number of steps I.e hotkey presses between min and max... If you increase your STEP size in the script so that the number of STEPs between 0 and max_brightness is the same as the number of steps the graphical indicator has, that might fix this minor issue.

    04:00.4 System peripheral: JMicron Technology Corp. xD Host Controller (rev 30)

    And, oldfred, yes, that is the install procedure I used but first time around I did the latter part and installed the most current driver downloaded from nvidia site, 64bit 310.19. It worked except for occasional crash.

    OK, where I am now is repeated the steps in that post and did first part and installed nvidia-current-updates.

    All is well except I get a "system problem" shortly after reboot. Telling it to report gives the nvidia crash report, stored in home dir. Purge should have cleared any old stuff but who knows.

    It's not the "end of the world" as we know it, just annoying. I'll leave it this way a while and perhaps an update will clear it or perhaps there is a driver/hardware bug. I am running generic as noted with nvidia-current-updates.

    If we have a difference in the models, ie, lspci shows something different than my model please advise.

    Thanks to you for patience and assistance. At least with this driver from repository I won't have to do it manually in future. But, just in case, I saved the scripts on my backup drive so won't have to recreate that.

    @kranthipls
    I have not seen anyone with the Lenovo summarize the install details. If you start at the first post and follow thru all the details are there, just may take a bit to sort thru.

    Also important to backup first both Windows & efi partition as one user in another thread used the overwrite entire drive option and erased Windows totally.

    If you like keep track of what you do and document in one post like these have done.

    There are only a few UEFI/BIOS vendors so your screens may be similar?

    You will need to use the 64 bit version of 12.10 and from the UEFI menu boot the flash drive in UEFI mode. That way it will install in UEFI mode.
    Systems need quick boot or fast boot turned off in UEFI settings. Vital for some systems. Best to backup efi partition and Windows partition first.
    Use Windows Disk Tools to shrink Windows main partition, but not to create any new partitions.

    Re: Lenovo Ideapad Y500 LiveUSB Problem

    Hi! Could anyone please give me a full alghorithm for successfull Ubuntu 12.10 install on Y500?

    What i've done:
    1. Enabled Legacy support
    2. Made a 500gb partition for Linux
    3. Installed Ubuntu there with default settings
    4. After it Ubuntu is runable only in legacy mode. And Win8 only in UEFI. It is pretty annoying
    5. I've booted from liveUSB, launched boot-repair with recommended settings
    6. Changed BIOS settings to UEFI and boot point to Ubuntu.
    7. It starts GRUB Menu. When i start Win8 from it - it can't launch it. When i start Ubuntu - only something like a quater of screen gows pure purple and nothing more happens.

    I've tried some magic with EasyBCD under Win8 and other stuff, but nothing helped. Default Win8 UEFI boots well and nothing more( In legacy mode nothing is launchable at all, i am getting grub rescue menu.

    I would appreciate any help, i'm pretty noob in linux and in disk partitioning and boot problems.

    Thanks in advance!

    Re: Lenovo Ideapad Y500 LiveUSB Problem

    My y500 can now adjust brightness. The next problem is the maximum brightness I can reach is very low.

    When I boot up, this is my brightness level.
    Code:
    $ cat /sys/class/backlight/nvidia_backlight/brightness
    2340
    $ cat /sys/class/backlight/nvidia_backlight/actual_brightness
    2339
    $ cat /sys/class/backlight/nvidia_backlight/max_brightness
    2339
    Ater I adjust brightness, my "max_brighness" was changed
    Code:
    $ cat /sys/class/backlight/nvidia_backlight/max_brightness
    127
    and I cannot increase brightness beyond this value.

    Any idea please?

    	VAL=$MAX
    fi
    
    echo -n $VAL > /sys/class/backlight/nvidia_backlight/brightness
    /etc/acpi/nvidia_backlight_down.sh:
    Code:
    #!/bin/sh
    
    test -f /sys/class/backlight/nvidia_backlight/brightness || exit 0
    
    VAL=`cat /sys/class/backlight/nvidia_backlight/actual_brightness`
    MIN=0
    STEP=10
    
    VAL=`expr $VAL - $STEP`
    
    if [ $VAL -lt $MIN ]; then
    	VAL=$MIN

    echo -n $VAL > /sys/class/backlight/nvidia_backlight/brightness
    /etc/acpi/events/nvidia-brightness-down:
    Code:
    event=video LCD 00000087 00000000
    action=/etc/acpi/nvidia_backlight_down.sh
    /etc/acpi/events/nvidia-brightness-up:
    Code:
    event=video LCD 00000086 00000000
    action=/etc/acpi/nvidia_backlight_up.sh
    Then you have to make sure those scripts are executable:
    Code:
    sudo chmod +x /etc/acpi/nvidia_backlight_up.sh
    sudo chmod +x /etc/acpi/nvidia_backlight_down.sh
    You also need to have permissions to edit the brightness file itself (this was one of the problems I ran into -- the keys were running the script, but I didn't have permission to change the file so nothing happened).

    I have a y400 and have tried to follow these instructions for changing the screen brightness, but I run into a few snags. The first is that nvidiabl doesn't seem to install properly - in fact the most recent version on github seems to be corrupt, so I installed the .deb of version .74 which appeared to work, except that after a reboot it never loaded, and typing "sudo modprobe nvidiabl" gives me "Error blahblah: No such device". It isn't listed in lsmod.

    And then when doing "sudo chown YOURUSERNAME /sys/class/backlight/nvidia_backlight/brightness" it says there's no such file, and likewise cat /sys/class/backlight/nvidia_backlight/brightness returns nothing.
