Try to create a eclipse.desktop file under /usr/share/applications (or ~/.local/share/applications or directly in ~/Desktop) with the following content:
[Desktop Entry]
Encoding=UTF-8
Name=Eclipse IDE
Exec=/path/to/eclipse/executable

Using PowerTop
yum install tuned-utils powertop
Run powertop under su to tune. To generated a profile, use powertop2tuned tool. E.g.
powertop2tuned bestbattery
This command will create a profile at /etc/tuned/bestbattery. To edit the profile manually check the tuned.conf inside that folder. If you want a specific USB device to be always on, set it to "on".
# Autosuspend for USB device G3 [A.....]
/sys/bus/usb/devices/3-2/power/control=on
tuned-adm profile my_profile_name
systemctl enable tuned
Installing Wifi driver
- Find out your wifi driver
lspci | grep Network
- Enable non-free repository
wget http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm
rpm -ivh rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm
dnf clean all
- Install wifi driver
dnf install akmod-wl
dnf install kernel-devel
- Note: If it's intel driver, iwlXXXX can be used. E.g.: https://apps.fedoraproject.org/packages/iwl7260-firmware
- Enable wifi driver
akmods --force
modprobe wl
iwconfig
systemctl restart NetworkManager
Fixing Wireless Connection randomly disconnects
su - modprobe iwlwifi 11n_disable=1
# to run on boot
su - echo "options iwlwifi 11n_disable=1" > /etc/modprobe.d/iwlwifi.conf
- Download the driver from Nvidia homepage http://www.geforce.com/drivers
- Update kernel, kernel-devel, etc.
dnf install kernel-devel kernel-headers gcc dkms acpid
- Disable default driver
echo "blacklist nouveau" >> /etc/modprobe.d/blacklist.conf
- Check which graphic driver is being used
lshw -c video
- We should see something like this
