  • Dark screen when wake / Unable to control screen brightness

    - by John
    Running Ubuntu 11.04 on Lenovo ThinkPad with an Nvida graphics card. The unit goes to sleep when the lid is shut. (The unit goes to suspend mode (not to disk/hibernate), AC gets turned off, running on battery) Upon lid-open sometimes the screen is almost too dark to read. I'm really not sure of the exact cause, (very low batt??). The only fix is a reboot. The screen brightness buttons have never worked in Ubuntu. I have messed w/ the power management preferences. No change. At one point I messed w/ the gnome settings. No change. I have tried a few cmds: echo 9>/sys/class/backlight/acpi_video0/brightness setpci -s 00:02.0 F4.B=10 xgamma -gamma .75 None of these help. Most have zero effect. I think it is and acpi thing, but that is just a guess. I'm out of idea's, and looking for suggestions. Thanks

  • Dark NetBeans

    - by Geertjan
    Let's make NetBeans IDE look like this. Not saying it's a nice color or anything, just that it's possible to do so: I changed the coloring in the Java editor by going to Tools | Options, then chose "Fonts & Colors", then selected the "Norway Today" profile and changed the background setting to Dark Gray. Next, I put this themes.xml file into the "config" folder of the NetBeans IDE user directory, which you can identify as such by going to Help | About in the IDE. Go to the exact location defined by "User directory" in Help | About, and then go to the "config" folder within that folder: The "config" folder of the user directory is the readable/writable root of the NetBeans IDE virtual filesystem. If a themes.xml file is found there, it is used, as described here. Then, in netbeans.conf file, which is not in the NetBeans user directory but in the NetBeans installation directory, within its "etc" folder, I added the following to "netbeans_default_options": -J-Dnetbeans.useTheme=true --laf Metal The first of these enables usage of the themes.xml file, i.e., it notifies NetBeans IDE at startup to load the themes.xml file and to apply the content to the relevant UI components, while the second is needed because most/all of the themes only work if you're using the Metal Look and Feel. Note: I must add that in most cases, whatever it is you're trying to achieve via a themes.xml file can probably be achieved in a different, and better, way. The themes.xml mechanism has been there forever, but is not actively supported or tested, though it may work for the specific thing you're trying to do anyway. For example, if you're trying to change the background color of a TopComponent, use the paintComponent method of the TopComponent instead of using a themes.xml file.

  • Laptop monitor being very dark, no backlight?

    - by ldigas
    I'm asking for a diagnose of what is probably the problem. Here goes ... laptop monitor (hp 6715s) went dark. I'm using also an external monitor with the laptop, and since it kept its picture, I'm guessing it's not the graphics card. When the night came, and I turned on my desk lamp, I noticed that the laptop monitor is not really not showing anything, but is actually showing my desktop picture - only it's very very very dark. You cannot see anything on it, unless the lamp is focused on it, then you can see the picture, only very dark. Does anybody have any clue what it could be? I'm just looking for informed guessed here, so I have at least some idea of where the problem lies. The closest repair shop is quite some distance away, so going for a bit of self-diagnose before thinking of taking it to them.

  • Dark Windows Themes

    - by CaffGeek
    I spend all day staring at computer screens. I have changed my Visual Studio theme to a dark theme, and find it much easier on the eyes. I'd like to change the rest of windows. Unfortunately, the only themes installed by default that are dark, are high contrast. Which is NOT what I am going for here. I can't seem to find an official dark theme, that isn't high contrast. I've found dynamic black, which is a good example of what I'm looking for, but it's not an official theme. Is there anything out there?

  • GPL the Dark Side

    - by EmbeddedInsider
    This blog is about the GPL Issues nobody talks about.  Its about the evil inherent in the GPL License. Evil?  But did not someone tell us that "open" is good?  Well, yes, and I might agree. It just depends on what we mean by 'open'.   There are many kinds of 'open' license, and many of these I like.  But  I maintain the GPL; the principle license of the Open Source Software Foundation, is most certainly NOT open for business.  And to the extent that software is conceived, developed, and maintained business, not hobbyists, the GPL is very, very evil. Controversial? You bet.  Flame away please. Lawrence Ricci www.EmbeddedInsider.com

  • SharePoint Apps &ndash; the dark side

    - by Sahil Malik
    SharePoint 2010 Training: more information First of all, I am a proponent of SharePoint apps. As I have said many times over, SharePoint Apps make me very ‘appy, they are very app-propriate. But there are some points to consider that make a bit app-rehensive. These are all mentioned in my book “SharePoint 2013 - Planet of the Apps”, .. but here are some thoughts of the negatives of Apps that I think we need to consider before diving in, Mutliple Servers, More Complexity Apps, by definition will include an extra server. This excludes SharePoint-hosted apps of course. Extra servers by definition will add more complexity. As it is, when you introduce SharePoint to an organization, the number of servers multiply like bunnies. Now you will have additional servers, and these servers talking with each other. You will have to maintain trusts, and you will have to patch more stuff, reset more “admin” passwords – you get my point. Read full article ....

  • WMV will play audio but not show images (dark screen)

    - by GUI Junkie
    This happens on one computer. On the other computer I can see the video. I've installed GStreamer, FFMpeg and Ubuntu Restricted Extras. On the computer where it doesn't work, I've tried both Movie Player and VLC. There must be some difference between the two computers, but how can I obtain all the system information in such a way that a diff could be reasonably done? Or just any other suggestion on how to solve this would be appreciated. :-)

  • Frustrated by the VS2012 'Light' and 'Dark' themes?

    - by ihaynes
    Like me you may be have been frustrated by the lack of colour in VS2012. The flat look, reminicent of the early 'Gem' OS is bad enough, but when the only choices are a washed out white look or the deadly all-black look, it's not an easy product to work with.Fortunately MS themselves seem to have quietly taken notice of this, or at least one of their developers has, and a 'Color Theme Editor' extension has been released. This comes with some much better colour schemes (I'm using the blue one, which is fairly close to VS2010) and also allows you to create and edit themes youself.This extension doesn't come up when you search 'Extensions and Updates' but can be found at http://tinyurl.com/6rhkdejWith this, using VS2012 finally becomes a pleasurable experience.

  • Brightness too dark or too bright

    - by YatharthROCK
    Basically, below a seemingly-arbitrary threshold (seems to be around 60%) my laptop screen is too dark to really make out much, and above that threshold it takes its maximum brightness (which is waay too bright for my eyes). This problem only occurs when I change the brightness using Windows' UI. Changing the brightness using Fn keys on my keyboard works as expected; unless the screen went into dark mode because of Windows, in which case they have no effect. This problem started occuring on my ASUS laptop very recently. My laptop has a poor battery, but I don't think that's related. What is going on? I tried resetting power plan settings, turning off adaptive brightness and restarting. I'll give any info asked for. Help required urgently...

  • Knight's tour / recursion

    - by Layne
    Hey, I'm trying to learn a little bit more about recursion but somehow I can't solve the knight's tour and I'm hoping someone can point out my logic error. public class main { static int fsize = 5; static int board[][] = new int[fsize][fsize]; static int[] sprung_x = {1,2,2,1,-1,-2,-2,-1}; static int[] sprung_y = {-2,-1,1,2,2,1,-1,-2}; static void SucheWeg(int schrittnummer, int x, int y) { board[x][y] = schrittnummer; if( schrittnummer == ((fsize*fsize)-1)) { for(int i = 0; i<fsize; i++) { for(int c=0; c<fsize; c++) { System.out.printf("%3d", board[i][c]); } System.out.println("\n"); } } else { for(int i = 0; i<8; i++) { for(int c = 0; c<8; c++) { if( (x+sprung_x[i]) >= 0 && (x+sprung_x[i]) < fsize && (y+sprung_y[c]) >= 0 && (y+sprung_y[c]) < fsize ) { if(board[x+sprung_x[i]][y+sprung_y[c]] == -1) { System.out.println("Move: "+schrittnummer + "\n"); SucheWeg(schrittnummer+1, (x+sprung_x[i]), (y+sprung_y[c])); } } } } board[x][y] = -1; } } public static void main(String[] args) { System.out.println("Begin: \n"); for(int i = 0; i<fsize; i++) { for(int c = 0; c<fsize; c++) { board[i][c] = -1; } } SucheWeg(0, 0, 0); System.out.println("\nEnd"); } }

  • Make an iPhone InfoButton light/dark based on color behind it

    - by Paula
    How do I detect what color is under the InfoButton... so I can change the button from DARK to LIGHT? I set my view's color... but how do I tell if it's "kind of light" or "kind of dark"? Besides... I can't change the info-button from light to dark anyway. (read only) Ugh. Shouldn't Apple have some kind of a simple "cmdButton.doThisExtremelyCommonThingForMe = TRUE" statement? InfoButtons are useless if you can't even see them. (Or how would I put an image behind the button to make it stand-out more?)

  • Dark color scheme for Eclipse?

    - by Bartosz Radaczynski
    Is Eclipse at all themeable? I would like to install a dark color scheme for it, since I much prefer white text on dark background than the other way around. Edit: so apparently there is NO easy way to do it. Shame, I really prefer Eclipse to NetBeans, but I cannot stand the white background (and NetBeans does support themes).

  • Photoshop - Turning white photo to dark photo

    - by K.M
    I've taken the original photo and I was playing around in photoshop and got to amended photo. I was stupid enough to not to save the file in psd or remember how I've done it. However,I definitely remember I pressed Invert (command +I / Control +I) and my white photo turned to proportioned dark photo. Does anybody know how? It was very simple step. It was accidental discovery. Would be great if someone knows the answer. See Original photo See Amended photo

  • TextMate suddenly highlighting all text dark red...?

    - by AP257
    I'm using TextMate on Snow Leopard, don't know much about how it works. After I hit an unknown keyboard shortcut, it suddenly decided to highlight almost all text in my Python files dark red - making all my Python virtually unreadable! I must have accidentally pressed a shortcut - but I've no idea what I did or how to turn it off, and can't find any relevant help in the manual or form. Even just 'turn off all highlighting' would do. Anyone know how to turn this highlighting off? Bit desperate! UPDATE: Figured it out. There's a tiny, tiny dropdown list at the very bottom of every TextMate editing window where you can set the language, so TextMate can highlight invalid syntax - I'd accidentally clicked on it and set the language to something other than Python. Will leave the question up though in case others have the same problem.

  • MacBook Pro screen goes dark

    - by Mike M
    I've had my MacBook Pro for two years now...no problems (it has had 3rd party RAM from the get go). Today, I'm copying a particularly large VM from an External disk drive to local MacBook disk. It has about 3GB to go and I take off to do some other things and when I come back my screen is "dark". The computer is still on but I can't see anything. I forced a reboot by holding down the power button, it starts up with the "chimes", but still no screen. I've done this several times. Any ideas? Do you think the hard disk activity caused it to get too hot?

  • Dark Windows 7 Screen

    - by user147521
    My Gateway laptop -Windows 7- screen became too dark a few days ago after I finished installing Windows automatic update. I can see nothing unless I use a flashlight. Windows login screen is the only bright screen for few seconds. What should I do to resolve this issue? I checked power-saving/ Power Options settings and rebooting in Safe Mode. I tried to lower the refresh rate but it did not allow me. The laptop adapter type is ATI Radeon Xpress series. I uninstalled and reinstalled the driver. And the driver is up to-date. Any help would be appreciated.

  • MSWord table shading prints too dark

    - by Relaxed1
    My friend has a very light shading in his MSWord tables. However they still print too dark to read the text. When emailed to a colleague using the same printer, it prints light nicely. However they cannot find any setting that is different between them. Any ideas? Thanks! (P.s. for myself this would help for non-tables also, when 'highlighting' text. I do know that 'shading' gives more colour options for non-tables, but it would be nice to know anyway. Thanks)

  • make emacs in a terminal use dark colors and not light font-lock colors

    - by vy32
    I am using emacs on MacOS 10.6 with Terminal. I have a white background. It's very hard to read quoted C++ strings. They are coming up in pale green. Keywords are in turquoise. After searching through the source I cam across cpp.el and have determined that I am using the cpp-face-light-name-list instead of cpp-face-dark-name-list. Apparently this function is supposed to chose the correct list based on the background color: (defcustom cpp-face-default-list nil "Alist of faces you can choose from for cpp conditionals. Each element has the form (STRING . FACE), where STRING serves as a name (for `cpp-highlight-buffer' only) and FACE is either a face (a symbol) or a cons cell (background-color . COLOR)." :type '(repeat (cons string (choice face (cons (const background-color) string)))) :group 'cpp) But it doesn't seem to be working. What should I put in my .emacs file so that I get the cpp-face-dark-list instead of cpp-face-light-list? Thanks!
