I installed the Ubuntu 14.04 on Asus Q502LA laptop.  Most of the things work fine, but brightness control does not work. First, everytime on reboot, the brightness resets to 100% brightness. Second, the keys (Fn+F5 and Fn+F6) do not work either.    I tried pretty much all of the suggestions that I could find here.  None of them worked. Did anyone have any success with getting the Fn+ keys working again to control the brightness in 14.04?  Thanks,
I've installed Ubuntu 16.04 on my Asus X555LJ.  But I don't know how to install drivers or how to enable function keys to controls screen backlight brightness.
Co-Buyer Automobile As a co-buyer on an automobile, can the other party take full possession? Both parties names are listed as the Purchaser's. Only one purchaser signed the retail order for the motor vehicle, and if so, how can one become a no co-buyer? Schengen Visa Expiration I have a multiple entry 90 days Schengen visa (category C) from 15 March 2014 till 21 Dec 2014.    With this visa I entered The Netherlands on 4 April 2014 and left there on 13 April 2014.    I am planning to re-enter The Netherlands on 19 Dec 2014 and leave there for London (I have a valid UK visa as well) on 21 Dec 2014, at 7 am from Amsterdam.    Am I permitted to stay in The Netherlands on 21 Dec 2014 or should I leave the country on 20 Dec evening itself? A more succinct expression for "The day before yesterday" Is there a more succinct expression for "the day before yesterday"?   In German for example, gestern = 'yesterday.' The prefix vor roughly means before, so logically, vorgestern means 'the day before yesterday.'   Similarly, morgen = 'tomorrow', the prefix über roughly means over, so again, übermorgen means 'the day after tomorrow.'  (In Mandarin Chinese also you have respectively 前天 &amp; 後天.)  Presumably, there are also similarly logical ways to say "the page after the next" or "the paragraph before the last", etc.   Are there no similarly succinct, and graceful, expressions in English? I am new to photography, and need a little advice. I currently have a .   To get rolling, where do I go from here? Does the camera matter? Is this camera enough to start with? QuickStart basic layout/template for web development? I'm looking for a quick start or template, or something, to get a web site's basic layout done quickly and looking fairly professional, and then let me do the coding.  I don't want a CMS, as this is for a highly customised reporting application, but I need something like frame header and two columns and frame footer.  I can design the pretty reports for the wide right hand column myself, as the left hand column menu. I am trying to override the menu.css file in the default Classy theme through my library file. I have read through the documentation, but anything I tried doesn't work.  What would be the correct markup to override or disable this file? Find no. of non negative integer solutions of $a+2b+3c = 200$ I want to find number of the non negative integer solutions of $a+2b+3c = 200$ (answer can contain $a,b,c = 0$)  Example one of the solutions is $a = 100, b = 50, c = 0$  I used stars and bars trick and here i get is  $\dfrac{\dbinom{200+2}{2}}{2 \times 3}$ but it is incorrect  any type of math is welcomed    what I have learnt from stars and bars technique is to find the solutions of $x+y = n , x,y,n &gt; 0$ are positive integers but I am confused with equation of type $ax+by = n$ where $a , b&gt; 1$ How can I delete a symbolic link?

I would like to be able to preview and capture photos from two cameras simultaneously, and download them to my Mac (recent laptop, Mac OS X 10.8.x). Being able to keep track of which photos were from which camera is also a must.  I see a couple of packages that will do this via USB tethering on Windows, namely  (which other than being on Windows, looks perfect for my needs) and . I certainly could run Windows on my Mac somehow, but I'd rather avoid that, if possible.  I haven't bought the cameras yet, and I do not have any requirements as to which cameras are supported (it seems the packages above only support Canons), other than that they be relatively inexpensive. This is a hobby-type project, not a $3000 dSLR-type project.  However, even if all you have is a dSLR solution for this problem, I'd still like to hear about it. Perhaps it will lead to related solution.  Inventive hacky solutions welcome! Add a non-breaking space to "reopen (1)" and its ilk If $f$ is continuous, nonnegative on $[a, b]$, show that $\int_{a}^{b} f(x) dx = 0$ iff $f(x) = 0$  "$\Rightarrow$" Assume by contradiction that $f(x) \neq 0$ for some $x_0 \in [a, b]$. Without loss of generality, assume that $f(x_0) &gt; 0$. Since $f$ is continuous, $\exists \delta &gt; 0$ such that $f(x) &gt; 0,  \forall x \in (x_0 - \delta, x_0 + \delta)$. Since $f$ is continuous on $[a, b]$, then it is Riemann integrable. Therefore $\int_{a}^{b} f(x) dx = \sup L(f, p)$ for some partition $p$. Now what I want to do is to show that the lower sum, $L(f, p) &gt; 0$, in that case its supremum is $&gt;0$, and that contradicts the condition that $\int_{a}^{b} f(x) dx = 0$. However, I don't know how to articulate it.  "$\Leftarrow$" If $f(x) = 0, \forall x \in [a, b]$, then $\int_{a}^{b} f(x) dx = \int_{a}^{b} 0 dx = 0$ How can I find help for new Ubuntu users?

Imported TIF has dark gray background instead of white using QGIS 2.6  I import a TIF file, and expect the import to show an image that has black lines on a white background (with some other colors here and there), as the native windows viewer will see a white background.   The file, 49MB, imports, but   The TIF image has a dark gray background instead of a white background  I can't tell why.   Any hints?  The same thing happens if I import the TIF image into georeference, which is how I discovered this in the first place.  I created/exported the TIF image using PDFCreator (from a print of a PDF to a TIF, using that program).   Within PDFCreator, I chose a TIF export that set the color map to 4096 colors, as the default created a TIF file that was twice as large.  On testing with the default size (16 million colors or some such).... That file imported and showed the background as white.  And I can't tell why, for that, either.   Any hints?  ======== In response to the comment/question by @BradHards:  The TIFFTAG_PHOTOMETRIC is not present in either file.  The gdalinfo for the large file and small file are identical, but for the presence of two extra lines on the file where the white background turns to dark gray.  Each band sets NBITS=4 for Image Structure Metadata: eg:     Band 1 Block=5100x68 Type=Byte, ColorInterp=Red   Image Structure Metadata:     NBITS=4 Band 2 Block=5100x68 Type=Byte, ColorInterp=Green   Image Structure Metadata:     NBITS=4 Band 3 Block=5100x68 Type=Byte, ColorInterp=Blue   Image Structure Metadata:     NBITS=4   Something about the NBITS=4 state turns the background dark gray.  Alternatively, there is some other problem with the PDFCreator export.

The previous owner re-set the phone, but did not remove the device from their iCloud.  It is asking me for their iCloud information when I try to set-up the phone.  I don't have contact with the previous owner anymore.  Is there a way to remove the device from their iCloud so I can use a new one?
