HOWTO: VinDSL Conky Script

**Rbbt** · November 2nd, 2012

I played with conky configs a little bit and I think I got what I want (: I disabled calendar and time part and added my old configs there. How does it look, what do you think (:

Looks great!

Glad you got it sorted...

2-NOV-2012 UPDATE #2

I spent most of yesterday experimenting with various combinations of kernels and nVidia drivers.

I finally settled on the latest, stable, Raring Ringtail kernel (3.6.5) and nVidia legacy proprietary drivers (304.60).

Heh! Guess what?!?!?!?

My Conky script didn't display the nVidia driver version, because I no longer had 'nvidia-current' installed.

So, today, I've been testing some alternative methods for calling up this system info.

If anybody wants to play around, e.g. test them, here you go...

BARGRAPH WIDGET
v2.1 by wlourf (07 Jan. 2011)
this widget draws a bargraph with different effects 
http://u-scripts.blogspot.com/2010/07/bargraph-widget.html
	
To call the script in a conky, use, before TEXT
	lua_load /path/to/the/script/bargraph.lua
	lua_draw_hook_pre main_rings
and add one line (blank or not) after TEXT
	
Parameters are :
3 parameters are mandatory
name - the name of the conky variable to display, for example for {$cpu cpu0}, just write name="cpu"
arg  - the argument of the above variable, for example for {$cpu cpu0}, just write arg="cpu0"
       arg can be a numerical value if name=""
max  - the maximum value the above variable can reach, for example, for {$cpu cpu0}, just write max=100
	
Optional parameters:
x,y	  - coordinates of the starting point of the bar, default = middle of the conky window
cap	  - end of cap line, ossibles values are r,b,s (for round, butt, square), default="b"
	    http://www.cairographics.org/samples/set_line_cap/
angle	  - angle of rotation of the bar in degress, default = 0 (i.e. a vertical bar)
	    set to 90 for an horizontal bar
skew_x	  - skew bar around x axis, default = 0
skew_y	  - skew bar around y axis, default = 0
blocks    - number of blocks to display for a bar (values >0) , default= 10
height	  - height of a block, default=10 pixels
width	  - width of a block, default=20 pixels
space	  - space between 2 blocks, default=2 pixels
angle_bar - this angle is used to draw a bar on a circular way (ok, this is no more a bar !) default=0
radius	  - for cicular bars, internal radius, default=0
	    with radius, parameter width has no more effect.

Colours below are defined into braces {colour in hexadecimal, alpha}
fg_colour    - colour of a block ON, default= {0x00FF00,1}
bg_colour    - colour of a block OFF, default = {0x00FF00,0.5}
alarm	     - threshold, values after this threshold will use alarm_colour colour , default=max
alarm_colour - colour of a block greater than alarm, default=fg_colour
smooth	     - (true or false), create a gradient from fg_colour to bg_colour, default=false 
mid_colour   - colours to add to gradient, with this syntax {position into the gradient (0 to1), colour hexa, alpha}
	       for example, this table {{0.25,0xff0000,1},{0.5,0x00ff00,1},{0.75,0x0000ff,1}} will add
	       3 colours to gradient created by fg_colour and alarm_colour, default=no mid_colour
led_effect   - add LED effects to each block, default=no led_effect
	       if smooth=true, led_effect is not used
	       possibles values : "r","a","e" for radial, parallel, perdendicular to the bar (just try!)
	       led_effect has to be used with theses colours :
fg_led	     - middle colour of a block ON, default = fg_colour
bg_led	     - middle colour of a block OFF, default = bg_colour
alarm_led    - middle colour of a block > ALARM,  default = alarm_colour

reflection parameters, not available for circular bars
reflection_alpha  - add a reflection effect (values from 0 to 1) default = 0 = no reflection
		    other values = starting opacity
reflection_scale  - scale of the reflection (default = 1 = height of text)
reflection_length - length of reflection, define where the opacity will be set to zero
		    values from 0 to 1, default =1
reflection	  - position of reflection, relative to a vertical bar, default="b"
		    possibles values are : "b","t","l","r" for bottom, top, left, right
draw_me     	  - if set to false, text is not drawn (default = true or 1)
		    it can be used with a conky string, if the string returns 1, the text is drawn :
		    example : "${if_empty ${wireless_essid wlan0}}${else}1$endif",

v1.0 (10 Feb. 2010) original release
v1.1 (13 Feb. 2010) numeric values can be passed instead conky stats with parameters name="", arg = numeric_value	
v1.2 (28 Feb. 2010) just renamed the widget to bargraph
v1.3 (03 Mar. 2010) added parameters radius & angle_bar to draw the bar in a circular way
v2.0 (12 Jul. 2010) rewrite script + add reflection effects and parameters are now set into tables
v2.1 (07 Jan. 2011) Add draw_me parameter and correct memory leaks, thanks to "Creamy Goodness"

Subtle change(s), I know, but now it displays the distro's 'code name' and nVidia proprietary driver version.

Here's how it looks...

The new nVidia regex should work for both nVidia OEM drivers & 'nvidia-current'.

If it works for both, please let me know, and I'll remove the old code, in the next data dump.

**pqwoerituytrueiwoq** · November 3rd, 2012

Code:

nvidia-smi -q | grep "Driver Version" | awk '{print $4}'

that is faster than

Code:

glxinfo | grep 'OpenGL version string' | sed -e 's/OpenGL.*: //' | cut -c '14-19'

Code:

~$ nvidia-smi -q

Thanks! I'll play around with it.

you can limit the output with -d eg

Yeah, I saw that, but...

I run 'Psensor' in the background.

Anyway, the code that you recommended worked great. I tested it in Unity, Gnome 3, and LXDE/Openface.

I'll edit the original post (above).

Thanks, again!

More tweaking...

Since the "code name" and "version" have been added to the "System Section", there isn't any need to duplicate them in the "Logo" area.

So, I took my avatar, turned it into a transparent .png using GiMP, and stuck it in the upper-right corner.

Of course, you could display whatever you wish... Mr. Bean sucking his thumb... your national flag, et cetera.

All other options are still available. I just commented them out.

.conkyrc

And, more tweaks...

This time, I added "Trend Arrows" to:

Sunrise
Sunset
Moonrise
Moonset

Seemed irrelevant, at first blush, but I find myself trying to calculate the time changes in my head, so... why not?
