Getting volume keys to work in KDE
Hi all, I tried to find an answer to this one on the net, and got only things that got me in the right direction, but not a complete answer. For the sake of documentation, here is how to get KDE to recognize your volume keys (or, for that matter, any other special key). The fact that it doesn't happen automatically is probably a bug in the keyboard layout code. I might file it there. This method works with no special processes running. It works whether kmix is running or not. It causes KDE to display visual feedback to the fact that the volume is changing. First order of business is finding out what is the keycode for your misfunctioning keys. Run xev. A new window appears, and any message sent to that window appears in the console that ran xev. Be careful not to move your mouse or press any key other than the ones you want mapped, as the messages form very quickly. Next, with the xev window active, press the keys you want to map. Your output should look something like this: KeyPress event, serial 34, synthetic NO, window 0x2a1, root 0x13b, subw 0x0, time 61891190, (-690,-222), root:(785,703), state 0x0, keycode 101 (keysym 0x0, NoSymbol), same_screen YES, XLookupString gives 0 bytes: XmbLookupString gives 0 bytes: XFilterEvent returns: False KeyRelease event, serial 34, synthetic NO, window 0x2a1, root 0x13b, subw 0x0, time 61891190, (-690,-222), root:(785,703), state 0x0, keycode 101 (keysym 0x0, NoSymbol), same_screen YES, XLookupString gives 0 bytes: XFilterEvent returns: False KeyPress event, serial 34, synthetic NO, window 0x2a1, root 0x13b, subw 0x0, time 61892564, (-690,-222), root:(785,703), state 0x0, keycode 212 (keysym 0x0, NoSymbol), same_screen YES, XLookupString gives 0 bytes: XmbLookupString gives 0 bytes: XFilterEvent returns: False KeyRelease event, serial 34, synthetic NO, window 0x2a1, root 0x13b, subw 0x0, time 61892564, (-690,-222), root:(785,703), state 0x0, keycode 212 (keysym 0x0, NoSymbol), same_screen YES, XLookupString gives 0 bytes: XFilterEvent returns: False This tells me that the key for reducing the monitor's brightness has a keycode of 101, and for increasing it of 212. Record the keycodes for all keys you are interested in. Also, notice that after the keycode you get, in brackets, keysym 0x0, NoSymbol. This indicates that the keyboard mapping does not know what this key means. If the key is defined, you output should look something like: KeyRelease event, serial 35, synthetic NO, window 0x2a1, root 0x13b, subw 0x0, time 62033566, (-65,-284), root:(1410,641), state 0x0, keycode 176 (keysym 0x1008ff13, XF86AudioRaiseVolume), same_screen YES, XLookupString gives 0 bytes: XFilterEvent returns: False KeyRelease event, serial 35, synthetic NO, window 0x2a1, root 0x13b, subw 0x0, time 62035609, (-65,-284), root:(1410,641), state 0x0, keycode 174 (keysym 0x1008ff11, XF86AudioLowerVolume), same_screen YES, XLookupString gives 0 bytes: XFilterEvent returns: False This means that I have already implemented what I'm writing about here, and keycodes 174 and 176 are already mapped to the Audio down and up respectively. If that is what you get, and the symbol indeed matches the key's caption, this guide will not help you (but check out a setting called global shortcuts in the program that controls the relevant operation). Also, if you press the key and nothing happens, this guide is also incapable of helping you. I would recommend switching to the textual console and pressing the key. If you get a message from the kernel saying that an unknown scan code was received, the situation is still salvagable. You can tell the kernel to map the scan code to the right keycode. If junk is displayed then the situation may or may not be salvagable. It might mean that the kernel misunderstands the scan code, but it might also mean (happened to me with a Microsoft PS/2 keyboard connected through a PS/2-USB adapter) that something in the hardware munges the scan code. If nothing at all happens, it is possible that the scan code never reaches the kernel, and then there is very little anyone can do. The next order of business is to tell KDE to make a map between the key code and the proper key sym. For that, we need a list of valid key symbols. On Debian, you can find this list in /usr/share/X11/XKeysymDB. Find there the right symbol for the key. For the audio keys, these are XF86AudioLowerVolume (volume down), XF86AudioRaiseVolume (volume up) and XF86AudioMute (mute). I'm sure the rest are fairly self explanatory as well (well, not all of them. For example, XF86Display is the key that switches between monitors - not exactly trivial mapping). Last, we want the KDE startup to make these mappings (which, like I said, probably should go into the PC keyboard definition - if anyone has the volume keys bound to a

[Telux] Next Meeting: High-Level Programming Concepts Using Perl 6 on 22-March
Hi all! The Tel Aviv Open Source Club will host part one of a series of talks by Gabor Szabo ( http://www.szabgab.com/ ) about High-Level Programming Concepts Using Perl 6 - on 22-March-2009. The meeting will take place at Tel Aviv University, at the Schreiber MathsCS building, room 008 on 18:30. So mark your calendars. For more information can be found at: * http://www.cs.tau.ac.il/telux/ * http://wiki.osdc.org.il/index.php/Tel_Aviv_Meeting_on_22_March_2009 With any other problems, feel free to contact me: http://www.shlomifish.org/me/contact-me/ Abstract: - High-level programming concepts using Perl 6 A series of presentations on learning and using Perl 6 from the ground up to the special features. Many would think that Perl 6 is just a new version of Perl and that it might only be interesting for Perl programmers. However, Perl 6 is in fact a compiled language running on a virtual machine that embraces many new concepts not found in most programming languages. The presentations will be equally interesting for Perl, Java and C# programmers. During the series of talks we will start by learning the basics of the language and will get to various high level concepts. For now we plan 2 sessions but if we need more time we'll schedule more meetings. Note After the talk we go to the café at the main entrance where we can continue the discussion. If people bring portable computers, we can get the off the ground on the spot. VirtualBox images will be provided with everything that is needed for playing with Perl 6 set up inside. So you may opt to bring a computer with VirtualBox installed. -- We are always looking for presentations on interesting topics. If you have an interesting idea for a talk, feel free to contact us and we'll co-ordinate a date. Regards, Shlomi Fish -- - Shlomi Fish http://www.shlomifish.org/ maukeI'm not interested in what you're doing; what are you trying to achieve?

Re: kchmviewer problem - correct contents page , but any other page are inaccessible
Hi Lev, Have you tried to decompile the .chm doc and recompile it? What I mean is you may have to use a Windows programme to do this such as Help and Manual or Help Scribble. I doubt whether there is a programme to compile ..chm programmes using Linux. However, I could be wrong about that. It is quite possible that there was an error when the original document was compiled in the beginning. Programmes like the above use the Microsoft Help File compiler programme (available free) to compress and at the same time make the hypertext links live. Some of these programmes convert pictures to ..png files. Help and Manual can even produce a live hypertext link .pdf file, which obviously should run with Linux. I doubt whether you will get an easy answer on this one, but likewise who knows. How big is the file? Maybe I might be able to help decompile and recompile it.
