Debian Multimedia :: Laptop Battery Monitor In LXDE

Apr 17, 2016

I managed to install Jessie on my new Lenovo Ideapad 100 and have been trying to put the finishing touches on it. I downloaded FDPowermonitor and the icon showed up right away. Then after a few minutes it went away and hasn't shown back up.

I think I need to modify /etc/xdg/lxsession/LXDE/autostart to include @fdpowermon but I cannot figure out how to have the permission and use a editor I understand.

I just log into LXDE with root... but there has got to be a better way yes? But that didn't work anyway...

Debian Hardware :: Lower Laptop Battery Charging State To Prolong Battery Life

Mar 2, 2010

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 reactionsĚ 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 MaintenanceĚ 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.

Debian Multimedia :: Keep Laptop Screen Lit When Plugging In HDMI Monitor

May 7, 2015

Where the script is for Gnome 3. When I plug the HDMI cable, the desktop expands to include both, but disables the backlight on the laptop monitor. I have to restart gdm3 or the laptop for the brightness control to bring it back up. First, why would it turn brightness to 0, and how do I change the default of that so it stops. I plug and unplug the HDMI regualarly while I wait for a new desktop and the laptop has to pull double duty.

I just switched from Ubuntu 14.10. It never blacked out a screen on plug in or removing. That means that there must be some way to do it, however, it used Unity and this is Gnome 3.

I installed KDE. It works as well. I will use it for now, but would like to get Gnome 3 to work. My default is gdm but I think I saw I can switch it to kdm.

Debian Hardware :: Driver For Battery In Laptop?

Feb 17, 2011

When I am working with Windows OS on the DELL-Vostro-1014 laptop the battery is working. If however I switch to Debian Squeeze OS the battery does not work. Running #hardinfo & shows that there is no battery. Am I right in assuming that the driver for the battery?

/sys/class/power_supply/BAT0 gives
model_name DELL X612G0
Serial No. 18069
manufacturer LG

What driver is needed, where to search for it and how to incorporate in the kernel 2.26.32-5-686 ?

Ubuntu :: Laptop With No Battery - Checking Battery State

May 1, 2010

Just 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?

Debian Hardware :: External Monitor As The Main Monitor For A Laptop

Sep 22, 2010

I recently installed Debian, using the amd64 Network Install .iso. I'm using XFCE4 as my desktop environment, and everything is working well... on my laptop's screen.

My desired setup is to have my laptop sitting on a well-ventilated shelf, closed, and to have an external monitor be my main monitor. I want this because I'm using my laptop as my "home" computer, so it never moves, and I don't like the keyboard/trackpad. My laptop has a VGA output, and I can get my desired setup on my Windows partition (not stating a preference ; just that the hardware CAN do what I want it to).

I've been working my way around the Internet for a few days, now, and I've got the commercial NVIDIA driver installed. If I run sudo nvidia-config --twinview I can get my external monitor to be part of the display, which is great, but it's part of a dual-screen monitor setup, which is not what I want at all, because (a) XFCE's multiple virtual desktops are good enough for me and (b) my graphics card is integrated, and I'm trying to squeeze every drop of performance out of my laptop that I can (1 gig of RAM; the less that my graphics card eats into it, the better). Plus, it'd be annoying to accidentally drop something on my laptop's screen, and then have to dig it out of the shelf in order to undo it. I'm not saying that I'm consistently clumsy, but I'd eventually end up doing it.

Ubuntu :: Network Manager Battery Icon On LXDE Panel?

Jun 30, 2011

I haven't got Lubuntu as such, I've installed LXDE to try it out with Ubuntu 11.04 sometimes. 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.

Ubuntu :: Battery Not Recognized On Laptop (and It Recognizes Laptop As A Desktop)

Apr 15, 2011

I have installed Ubuntu (both 10.10 and 11.04 pre-release) on my laptop but my battery is not recognized and it is detected as a desktop system rather than a laptop. I have tried the cat /proc/acpi/battery/BAT1/state method but the directory doesn't exist. I have tried another guide to paste the battery info into this directory but it doesn't allow me to do that and says that the directory doesn't exist, even though I'm trying to make it. I tried it in root nautilus and even on an install of Lubuntu (with a root file manager) but it still failed to budge. I really don't know what to do as I have tried all the guides on the internet that I could find.

Debian Multimedia :: Enable Hotkeys With LXDE On Jessie

Apr 27, 2015

I've been using debian for well over a year, previously with the gnome desktop. I never really liked how much memory and CPU it used, but many things like the hotkeys worked out of the box, and it was relatively easy to configure. After upgrading to Jessie I decided I'd give LXDE a go given it was lightweight and seemed more complete than e17.

However, after over a day struggling to get everything to work just right, I am still unable to use use my hotkeys (volume control, brightness control, etc.). The volume can be controlled through the GUI, but the brightness seems to have no control whatsoever. In any event, I installed the drivers and firmware for the hardware and used the instructions in the link to try and configure the key bindings, but nothing has worked: [URL] ....

:Questions#Change_hotkeys I'm not sure what to do now.

Debian Multimedia :: Faulty Icons In LXDE Task Bar Since 8.0

May 2, 2015

I saw that on every computer in which I installed LXDE on Debian 8 (the problem was not existing on Debian 7.8.0)

So I decided to use mate-desktop-environment but a brand new problem (always ) made his apparition when I try to use tightvncserver on a Mate desktop (no task bar, and memory growing GB after GB up to the memory explosion after 1 or 2 minutes with 16GB RAM -I will post another subject for that once I will know more things about it - since it is, after all, an huge problem causing the computer to crash if "reboot" our "vncserver -kill :1" is not quickly done)

But here talking about LXDE taskbar: others LXDE users, do you have this problem with the icons ?

Debian Multimedia :: LXDE: Wallpaper Via Command Line?

Feb 20, 2010

Env: Lenny LXDE
[Question]

By (first step) doing: pcmanfm --set-wallpaper /point-to-new-wallpaper, it change the configuration to the new wallpaper, then, my question is: What is the most correct way to "refresh the desktop screen" (by command line) so that the new wallpaper is then displayed.

And by (second step) doing: lxsession-logout, and choosing 'Logout', the new wallpaper is displayed after the new login. No problem here. Is there a (most correct) way to completely change the picture and activate it by command line (without user intervention)?

Debian Multimedia :: Keyboard And Mouse With No Response After LXDE Boot

Feb 11, 2015

I use the debootstrap to make a base Debian System of the ARM architecture for BananaPro [URL]... , and install the LXDE desktop. But the keyboard and mouse didn't response after the LXDE boot.

If I use the Debian system without the LXDE desktop, and it is normal. Meanwhile, I only installed the framebuffer driver, and can't find the right GPU driver to install.

Is caused by the lack of the GPU driver ? and what should i do ?

I get some error logs from /var/log/Xorg.0.log file,as follows:

Debian Multimedia :: Jessie - LXDE Doesn't Shutdown Properly

May 19, 2015

I know the problem has been partly solved in this old thread [URL] .....

Now we have Jessie as stable, yet LXDE doesn't shutdown properly:

On the same computers, Wheezy LXDE shut down very fast

I installed Jessie from the netinstall image.

On a 2007 computer, it's like the old days with a Pentium II running some version of Puppy Linux or Slitaz. The system shuts down after a while but the computer remains on.

On a 2013 laptop, I added the line init=/bin/systemd in the Grub default file as advised on the old thread above. The laptop shuts down after a while, the system first, then the hard disk goes to sleep, then all the leds are off.

If I run the magic command, the computer shutdowns in a breeze, perhaps even quicker than good old Wheezy:

Code: Select all# systemctl poweroff

Now, is this still a systemd bug? Doesn't look like it since the systemctl command works. Is it an LXDE bug? Looks like it in a way - if the LXDE shutdown button enabled the systemctl poweroff command, I suppose the button would work?

Is there a way to make the LXDE shutdown button run the systemctl poweroff command?

I'm glad Wheezy is still with us because I wouldn't install Jessie for newbies ‚ÄĒ they'd think shutdown (through clicking on a button) is even worse than in Windows.

Debian Multimedia :: LXDE Desktop And Taskbar Icon Configuration?

Aug 1, 2011

The first issue is adding launch icons to the task bar. I can add launchers, but cannot figure out how to link them to applications. It is only half a problem, because putting links on the desktop is easy, but I prefer having launchers on the task bar so the desktop is not cluttered.The big problem is placement of desktop icons. I like to put icons on the right side of the screen, and more importantly, I like to group related icons. For example, if I had a folder or document for Linux and another for Debian, I want them grouped together. I also like arranging by category: folders in one column, documents and images in another and launchers (if any) in a third. However, if there is way to enable desktop icons to be moved, I cannot figure it out. Icons are fixed on the left side of the screen with folders first in alphabetical order, then documents/images in alphabetical or numerical order, and launch icons last.My guess is icons can be moved, but I am not computer literate enough to figure it out. It does not make sense that the task bar can be placed on the top, bottom, left or right, but desktop icons cannot be moved. I have tried every preference setting, but there are no relevant options.Am I over-looking something that is not obvious or is it a strange deficiency with LXDE?

Debian Hardware :: Connect A 2nd Monitor To Laptop?

Jul 14, 2010

I am using my laptop, hp compaq6710b with an external screen connected to that with the extended desktop options, which really increases the efficiency for programming and reading documents and doing changes.

I was wondering how to connect a 2nd external monitor to the laptop. Laptop has one VGA output apparently which is connected to the external monitor for the moment. I saw that there are some converters from usb to DVI-D or VGA. I guess these connectors can make the conversion I am looking for. Anybody used these connectors with debian to get an extended desktop on 3 screens(2 external monitors + laptop screen).
