For waking up from suspension, I create the following script /etc/pm/sleep.d/brightness: #!/bin/sh case "$1" in resume|thaw) echo 170 > /sys/class/backlight/intel_backlight/brightness ;; esac And the permission of the script is -rwxr-xr-x.

Expanding on the current answer, get the output name of your screen by running: xrandr --current You can determine if the screen is running if it has 'connected' next to it. For me, the display was called eDP1 So, I can change the brightness by runnning xrandr --output eDP1 --brightness 0.5 And replacing 0.5 with any value

First off, I don't think this is an Ubuntu question but more of a windows question, however I shall give you a quick pointer - It is most certainly possible to do, but it does break the Microsoft terms of service and therefore is illegal. Because you will be dual booting, you will already have a copy of windows installed on the computer, adding a second copy ...

The solution is to run xrandr then find the name of your default display. In my case it was LVDS-1-0. Then to make it the default, I ran this command: DISPLAY=:0 xrandr --output LVDS-1-0 --auto That solved everything for me, I can now use my laptop without having to plug in a HDMI cable connected to a monitor anymore.

I had a very similar problem and spent several days trying to get my card working. I have an ASUS X550LN which has an Intel Graphics Driver on the CPU and a dedicated NVIDIA GEFORCE GT 840M. First, installing the nvidia-340 drivers would cause Unity and Gnome to fail when launching. I could drop to a shell Ctrl + Alt + F1 and remove the driver sudo apt-get ...

For me, doing this was not enough. I needed to let my thumb at the bottom of the touchpad (ready to click). Actually, the AreaBottomEdge don't disable the "finger counting" on the dead zone and resting your thumb enable the scroll. Quite annoying.

Surface temperature The question is about an unusual surface temperatue distribution on the body of a very thin notebook. It basically asks "Is that normal?" Misconfigured?

For a couple of years, I serviced the laptops of a larger German car manufacturer. I've seen all kinds of Toshibas, Compaqs, IBMs / Lenovos and HPs. On some (I can't recall the brand though), you could see a read-only BIOS entry, listing the "battery order", but it was neither changeable through the BIOS nor the system. On none of all these laptops it was ...

Since, your machine is of 64bit, it would be better to install a 64bit OS. I am not saying that a 32bit OS can not run in a 64bit machine rather if you install 64bit OS, there will be a lesser amount of battery consumption. Plus since you are using two OS s simultaneously, the drainage of battery would obviously be higher.
