Fix Touchpad tap to click not working on Linux mint 16 petra

January 18, 2014 Leave a comment

Touchpad tap to click is by default disabled on Linux mint 16 and you can easily enable it by going to System settings -> Mouse and touchpad -> TouchpadĀ  and selecting “Enable mouseclicks with touchpad”. This is fairly straight forward.

However, for some people who have upgraded from older versions of Linux mint instead of doing a fresh clean install of Mint 16, they might have two versions of system settings installed, like shown below.

Both are different system settings application and not displayed twice due to some menu configuration error, it’ll become obvious once you open both side by side.The fact that both applications have the same name and icon is very deceptive for the normal eyes.You might have used both applications but you might be unaware of this fact, unless you look for it. Here, is a screenshot showing both opened side by side.

Applicaion window open in the right is Gnome settings application and any changes you make through here is not of any use, unless you are running Gnome desktop. Window shown in the right is the cinnamon system settings application and this is where you have to make your changes if are running default Linux Mint Cinnamon desktop.

Here is a comparison of how touchpad settings looks in both Gnome and Cinnamon settings applications.

Cinnamon system settings is easily distinguishable from Gnome settings by the fact they have a “switch to advanced/normal mode” link at the bottom of the application screen. Finally, the link has found some way of being actually useful šŸ˜‰

gnome-control-centre is the application responsible for Gnome system settings, it has a lot of dependent applications, that removing the application will mess with your system, unless you know whatĀ  you are doing. So, if you are not absolutely sure what you are doing, I’ll ask you to not remove it.

configure battery power settings in Gnome

January 25, 2013 Leave a comment

Gnome desktop does not allow users to set the values for battery critical state, Power settings will only allow users to set what action is to be taken when the battery is critical. By default it is considered critical when battery backup time isĀ  5 minutes and it will initiate battery critical action when backup time remaining is 2 minutes. This default behavior is questionable because 2 minutes will not be sufficient for all users to find a power source and as most batteries used today are lithium-ion batteries, their life will get significantly reduced by this default behavior when drained so low so often.

Fortunately, this can be changed in configuration editor. systems using older Gnome versions such as Gnome2 desktops had a tool called Gconf-editor to change these configuration settings. Newer Gnome versions such as systems using Gnome3 desktop use a tool called dconf-editor to make changes to these configuration settings.Install this tool by using below command from terminal

sudo apt-get install dconf-editor

After installing open dconf-editor and look for following path in the left pane

dconf-editor

/org/gnome/settings-daemon/plugins/power/

In the right pane look for the fields,

time-action

time-critical

time-low

and change the time values for the fields according to your preferences.Note that the time is defined in seconds.

Description for the fields and the type of value it accepts will be available at the bottom pane, when you select the fields.

Alternatively, if you want your system to consider the battery percentage instead of remaining time, uncheck the key

use-time-for-policy

and modify the keys

percentage-action

percentage-critical

percentage-low

to your preference.Now your system should take the values you defined after the next boot or restart your system for the settings to take effect immediately.

Solve Eclipse showing empty dialog box in linux

May 24, 2011 2 comments

All of a sudden my eclipse IDE started showing empty dialog box after working fine for some days. Most of the solutions found talks about Xulrunner problem that doesn’t work for me. A simple solution would be to just move your workspace folder to a different location or delete it if don’t have any important projects inside it and start eclipse again.Now you are good to go.

conserve battery in gnome when the system is idle with a little tweak

October 5, 2009 2 comments

I recently bought a new lenovo laptop and decided to install Linux mint 7 on it along with vista.Every thing worked fine by default.I started tweaking the system so that i could achieve longer battery life,and i wanted to post my experiences ,thus this post.This should work well for all gnome desktops.At first i couldn’t change the time when the display goes to sleep when idle,to less than 11 minutes as you can see below:

by default

by default

But this can changed easily by changing the idle time in gnome screen saver preferences,just open screensaver from system->preferences menu.

by default

by default

change the “Regard the computer as idle after:” slider from 10 minutes to your liking,i changed it to 1 minute as below:

changed to 1 minute.

changed to 1 minute.

now computer is regarded as idle after 1 minute and open power management preferences ,now you can reduce the “put display to sleep when inactive for:” slider to upto 2 minutes.As display is the major power consumer in the laptop you can put it to sleep quicker to save more power,when ever you are away.

after editing

slider can now be reduced upto 2 minutes

For more power management options install and run powertop application and it will suggest some options to further reduce power consumption and you can also identify which applications often wake the cpu from idle,also note that it will be useful only when you have an intelĀ® cpu.For further information on power conservation in linux visit http://www.lesswatts.org/
