For it to be practical for me I need the battery icon and Network Manager on the panel. I'm assuming this can be done easily enough as Linux Mint LXDE has got it, or Network Manager at least. i need NM to easily start my Mobile Broadband dongle's connection.Also, can touchpad tapping be turned off in LXDE, and how? I have it set up to have no tapping in regular Ubuntu but this is undone when I boot LXDE.
View 5 Replies View RelatedJust installed 9.10 followed by a 10.04 upgrade (wouldn't work as a 10.04 clean install). The install and upgrade all seemed to go well.
But now when booting I get a message saying "checking battery state" and then it boots no further. This is a laptop without a battery installed, running permanently from the mains through the charger.
How can I disable this check so that the laptop will still boot without a battery fitted?
getting back to our laptop, the stability window is ~3.2V. Meaning that when you operate the battery above this the electrolyte is oxidized on the positive electrode and reduced on the negative electrode. Remember that we only want to oxidize and reduce the active materials and don't want to do anything else. All these reactions other than the ones we want are called side reactions and these are really bad for the battery. The nominal voltage of a laptop battery is 3.7 V which means that something bad wants to happen as we use the battery.So long story short, stuff (e.g., passive layers and poor kinetics of reactions) happens and things are not as bad as they seem and you can increase the voltage up to 4.2V without bad things really happening. All chargers for Li-ion cells today cut the battery off when it reaches 4.2V. What you have to realize is that at 4.2V, these side reactions are present in finite amounts and start to chemically kill the battery, but its not that dramatic.
Operating to 4.1V makes things better and extends the life, 4.0 V is even better and so on. So why don't battery manufacturers cut the voltage off at, say, 4 V to get better battery life? Because every time you cut this voltage down you decrease the capacity of the battery and its run time. The 4.2V cutoff is a compromise between good run time and decent (read "not pathetic) life.On the other hand, if you charge the battery and then pull the plug (so to speak), the battery discharges some, the voltage drops, and these reactions become less of a problem and your battery life goes up. So the best things you can do is to charge the laptop (or cell phone, camera etc.) and once its charged, pull the plug. Your battery will thank you for it.As a matter of fact, if you own a Lenovo Thinkpad, you can actually change the state of charge to which you charge the battery using the Battery Maintenance utility. You can change this from charging to 100% state (where the voltage is 4.2V) to 90% so that your voltage is less. You lose some energy is doing that, but atleast you can change it to 100% when you need battery power and put it back down to 90% when you can plug in. I wish my Mac has the same feature.
I typically use the battery for a while (say 1/2 hour to 1 hour), then plug it in and wait to fully charge it, then I pull the plug and use it again for 1/2 hour to 1h and then I repeat this. Takes some getting used to and I forget to do this, but I try.
I have a 3 year old laptop with the original battery and its drained pretty bad. The "Battery may be broken" popup was driving me insane and this is how you disable it, in case you are in the same situation as me. Open terminal
Code:
gconf-editor
Drill down to...
apps --> gnome-power-manager --> notify
uncheck the low_capacity checkbox. This should disable the popup for you if your battery has little life left in it. Now, if any knows how to disable the Avahi popup, let me know.
Is there any USB mouse battery indicators for Ubuntu that can tell me the battery level of my Logitech USB mouse? (something like a laptop battery one) I want to add it the panel.

View 6 Replies View RelatedI'm using Kubuntu 9.10 and I have a problem with my screen. I use the nvidia driver downloaded from the website, installed manually as I always do. I wanted to update it, but when I press ctr-alt-F1 to go to the console to stop kdm, I cannot see the usual black screen, but only a very strange blinking screen with lines and colours, strange symbols like $ & %. This happens for every F1 until F6, then F7 luckily brings me again on the graphical desktop.
I tried to install the drivers from the "Hardware drivers" manager in Kubuntu, but nothing changed. I don't know if it's an issue related to the kernel or to the driver. But I don't know how to update it without F1 console, and however it's a serious issue because I cannot do anything in case of desktop failure. The kernel is the last officially released (I don't use the proposed repos), that is 2.6.31-19.
I'm getting a screen that has what looks a like a keyboard, equal-sign, then a person in a circle. This happens when I go to install it. I have made new discs and everything and nothing but the screen.

I have an HP Laserjet 2200 connected via USB with 64MB of memory. When I print page 2 of this document (for example) [URL] the delta-symbol and minus-signs do not show up, although I see them in Adobe reader version 9.3.
I have tried several of the available drivers for the printer (including the "[recommended]" one) and none of them produce these symbols.
I'm guessing this is a font issue. I don't know how to show you what font stuff I have installed.

View 3 Replies View RelatedI'm running gdb across a network using gdb server. I've got it up and running. However I can't see any source or variables for my code (in ddd /gdb). At start up gdb says (no debugging symbols found). I've got a g in my make file,
CPFLAGS = -Wall -Os -g -pedantic
I've tried loading symbols in using "symbol-file testarm", this sort of works in that I can view symbols but not names, e.g. if I ask dd to show x y and z, rather than
x = 10
y = 20
x = 30
It says:
display
10/20/30
Also ddd does not show anything in the source window, is there a way I can get it to show this? I think it's because I've started ddd with ddd arm-linux-gdb, as I'm calling a crosscompiler gdb. So can I tell ddd to point to the correct folders? What commands I need to set in gdb/ddd to view variable names (it's hard to keep track when it bunches them all together) and how to view my source code.
I decided to try making a programming language again after my last unsuccessful attempt, so now I figured how to write a good AST and it works great when the nodes are hard-coded into a test program. But to make a language out of it, I need a parser to build the tree according to an input file. I ran into a problem here:
YACC input file:
Code:
%{
#include "nodes/allnodes.h"
#include "Node.h"
int vars[26];
%}
%token SEMICOLON INTEGER VARIABLE IF WHILE DO OPAREN CPAREN OBRACE CBRACE
%right ASSIGN
%left NE
%left PLUS MINUS
%left TIMES DIVIDE
%% .....
As you might see, each nonterminal creates a Node* object and uses it as its value. The problem is that the literal tokens, however, don't return Node*'s and I don't know what to do. I would like to be able to convert literal tokens to nodes in the Lex file (which would avoid the problem), but the problem is with the assignment operator, which takes a Node* for the right-hand side and a variable name (not a Variable Node, because they just evaluate the the variable's value and you can't change the variable with them) for the left hand side.
I was going through some exercise given in my school. I have read the C book but I am not able to understand some part. That is static variable. What exactly is a static variable and what does it do? I saw in Linux Kernel Programming external and exported are also some thing. I am not getting the difference between static,EXPORT_SYMBOL,external variable types. If I make a kernel module then how will I make sure that my variable is visible to the kernel. Is this what it is all talking about? I have checked this page [URL].
View 2 Replies View RelatedWhen I used slackware 13.0 I installed wine 1.1.40 and then I installed an old program, PowerTAB. The font for the mf, mp, and other symbols was very small and unreadable. To solve this I put sylfaen.ttf in /home/darksaurian/.wine/drive_c/windows/Fonts and this magically fixed the problem. I don't know why or how I figured it out.

Is there a way to set up a custom keyboard layout? (ex: set q to the f key, etc.) I have looked around, but have been unable to find one.
If there isn't one, then a (basically) equivalent solution for me would be to map some of the symbols I need (ex: Δx,Σ,ect.) to ctrl-/,ctrl-., ect. through keyboard shortcuts. The problem I run into here is that I do not know of any commands that paste a specific symbol into the focused text input area. Does anyone know of one?
How do I get debug symbols for glibc? I'm using oprofile when profiling applications. Unfortunately, the default glibc version that comes with SUSE 11.1 has the debug symbols stripped-out. That means that all libc functions get aggregated into one big blob under "glibc.so" and you can't tell whether you spend most of the time in memory allocation, syslog or lock related routines.
So, I've tried a myriad of different ways of getting the symbols. From trying to build glibc myself to hunting for dozens of different rpms on this site and on the Internet. So far - no positive results.
My sytem: OpenSUSE 11.1, x86-64.
I followed the instructions at
OpenSUSE: Bugreport KDE - openSUSE
to install debug symbols for okular which seems to crash quite often for me. However gdb and the kde crash application are unable to find them. The kde app says its not a good crash report and I should follow the guide.. which has already been done.
I installed
kdegraphics4-debuginfo
kdebase4-runtime-debuginfo
kdebase4-workspace-debuginfo
kdelibs4-debuginfo
libqt4-debuginfo
Is there a step I'm missing to get gdb to load the symbols or something?
For PE executable, I can list the imported symbols using
