Hi everyone! I've just installed fedora 19 on my acer aspire v3-771g with the desktop environment GNOME and i have 1 problemM: My pc overheats quickly also without using applications (it's a new pc and it doesn't heat with other systems), anyone knows how to solve it?
1) Overheating issue
Your laptop seems to have two GPU (optimus technology) :
You need to use Bumblebee to desactivate the second GPU. To do so, follow the steps below :
2) Lack of brightness control
You can use a GNOME Shell extension to control the screen brightness when the keyboard shortcuts don't work : Brigtness Control.
If it doesn't work for you, maybe this blog post will help you a little bit. You can change the brightness in the BIOS when starting the computer (which is a work around not very convenient) or there are other methods that involve command lines (see the comments).
Let me know if you have issue installing and configuring Bumblebee.

OK, i've installed bumblebee but i've problems with the configuration, i open /etc directory, than bumblebee an than bumblebee.conf, i modify the strigs how is told to do in the page https://github.com/Bumblebee-Project/Bumblebee/wiki/Configuration but i can't save the file modified because it's a "only read file", what i'm doing wrong? ... about the brightness the GNOME extension doesn't work, i can move the cursor but the brightness doesnt't change :/
You have to open the file as an administrator to be able to modify it. Open a terminal, type
su<enter> your root password <enter> to connect as an administrator. Then to open the configuration file type :gedit /etc/bumblebee/bumblebee.confok i did it and i rebooted but i can't see changes, te fan continues to spin at maximum
if i give "optirun glxgears -info" this is the answer:[ 241.540249] [ERROR]The Bumblebee daemon has not been started yet or the socket path /var/run/bumblebee.socket was incorrect. [ 241.540310] [ERROR]Could not connect to bumblebee daemon - is it running?
To check if the card is successfully disabled, type the command
cat /proc/acpi/bbswitch. The result shoulf be... OFF. It seems like in your case, the bumblebee deamon is not started yet.
