enabling tap and circular scroll on touchpad and modern debian/X

Ok, if I get things correctly, I need to setup a udev rule for each

Okay missed this the first time around, i did not realise it was a
udev rule and not a hal rule
I though the doc said to use fdi rules to configure the touchpad
It's a moving target, that's the problem.
Until version 7 or so of X it was via xorg.conf (had that setup pretty well).
Then the default changed to hal to allow auto detection and that was fdi rules.
There was actually quite a bit of screaming about it on the list at the time
since there were people who really didn't like hal. Now for quite some time (at
least in unstable, not sure if it propagated to testing already) hal is mostly
deprecated in favor udev so the fdi files no longer work and everything has to
move into udev.
Problem is that as far as I can tell there is very little documentation on
both. A few more examples on hal by now, couldn't find anything useful on udev.
I need to finish a couple of deadlines and I'll test Sjoerd file. Looks easy
enough to adapt to my needs which is great. After that I'll see if I can manage
to modify it also handle my trackpoint and usb mouse.

Dou you have a synaptics touchpad? When I get home, I can mail you my
udev rule for tapping and two-finger scrolling.
Sjoerd
Yes, it's a synaptic (it's a thinkpad t61)
Then putting the below in your /etc/udev/rules.d/66-xorg-synaptics.rules
should work, at least for two-finger scrolling. Making it work for
circular scrolling must be trivial.

Is there a command line tool for creating 3d text effects?
I'm trying to get some nice 3d text into beamer presentations for the title instead of the boring standard text.

mounts via init.d early in the boot process
I have a system where I use a readonly nfs root with a local hard drive and I need to have some local settings for each computer (mainly /etc/hosts, ip address for network devices, hostname and nfs server settings). I do that by mounting the local disk on /local and then overiding some settings using unionfs (will be happy to hear of a simpler method). Anyway, I have a link /etc/rcS.d/S05mount_local which is supposed to run after /dev is populated and before most other things and the main thing it does for this purpose (or the main thing that fails) is a call to mount -t ext3 /dev/sda1 /local with the error /dev/sda1 already mounted or /local busy since root is an nfs root then it should be mounted This happens also on the main node where /dev/sda1 is root and also on the slave nodes with nfs root. Running the same script after the machine finished booting works fine and the script used to work find buffer so it's something pretty recent, probably in unstable, that broke it. Any idea what it is or how to fix it? Thanks -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble? Contact listmas...@lists.debian.org

syncing sony erricson phone with linux
Is it possible in a stable way to sync a sony erricson phone (k800i) with linux (calendar and contacts)? I tried to google but all I found was seriously outdated, the main current reference seems to be opensync which I tried at the time but it failed miserably and it doesn't seem like the version number went anywhere. Regrettably what I'm doing now is to use my phone explorer in windows and transfer information via google calendar but it's a horrible solution. I'm currently using iceowl for calendar and I haven't found a descent contacts manager, but I'm open to suggestions on both (preferably not gnome/kde and if it's a mail program it has to support my own mail directory which AFAIK neither mozilla, evolution nor kmail do, I'm currently using claws for mail which is great but doesn't have descent contacts support) thanks -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

remapping bluetooth mouse buttons (microsoft notebook presenter 8000)

Pretty much technically not feasable and from a scientific point of view, not even mathematical Think of it this way, if you want to cancel a sound wave you and another sound wave traveling in the same direction but inverted. Think of sea waves, you need to invert the wave. If they travel at different directions they will cancel at some points and add at others and may not even exist together at some places. You would also get different effects at different wave lengths due to the differing relative error. This mean that you need to cancel the wave exactly at the source or on a complete sphere around the source (with an accurate rendition on that sphere which would mean nano speakers). The second problem is that you also need exact measurements to create the cancellation wave, also on the entire sphere, and to take account the delay between measuring and reacting (even assuming zero time computation). This is only partially feasible at the headphone level where the listener and speaker are close together with a know orientation relative to the microphone, minimizing the relative error, this also explains why you get noise reduction and not noise cancellation and different effective with different noises (depending on the uniformity, pitch and direction). A good algorithm also needs to take into account where the speaker, microphone and listener are all relatively located and take an assumption on the direction the noise is coming from. It may be feasible to improvise noise cancellation headphones though, by sticking a microphone on the headphones and feed the input back inverted with the correct delay and volume. At this level it would only take some electronics, no processor at all. I don't have the time though to create a simulation at the moment to see if you need some processor based optimization of not.

Anthony You don't have to re-install your system, that's for sure. Since you chose to upgrade to grub2, spend some time reading its documentation and then from a live cd that supports grub2 try to make it function. Needless to say, you can always revert back to legacy grub and rewrite menu.lst (I can't understand who deleted that). there is not menu.lst in grub2, look in /boot/grub/grub.cfg for the current configuration although it is generated from files in /etc/grub.d and /etc/default/grub using /usr/sbin/grub-mkconfig based on the start of that file No worries though, your system is there, waiting for the right bootloader config in order to boot again...

I've googled about that and learned what NUMA is about while trying to answer the question wheather I should enable it in my kernel or not. But I couldn't find the answer I was looking for. Do Intel DualCores (E8400) support NUMA? Do you need special hardware, like a special mainboard supporting NUMA, to benefit from this feature? Do these CPUs support NUMA? It seems to me that leaving it disabled is better in my case, and the kernel help also says that it's probably better not to enable it if you don't have more than two CPUs/cores. Now if I had a quad core CPU instead, would I better enable NUMA? Or if I had an AMD instead of Intel, would I turn it on? Or should I leave it turned on? A good first answer is that if you don't know what NUMA is then you don't need it. If you want a more precise answer what NUMA is: NUMA = non uniform memory access. It means that each cpu connects directly to it's local memory and slowly (via some communication channel) to other memory. The closest you would get with a desktop box (which I don't think is possible yet) would be with a dual CPU core i7 (note, dual cpu, not dual core), since corei7 has it's own memory controller. Core 2 duo connects via the north side bus and thus even with two CPUs they still connect to the same memory via the north side bus. If you have a multi CPU opetron system they also are NUMA systems. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

OK, but libc6-i386 is not installed. And I (or rather my wife) needs
skype installed. I'm not sure what to do now.
You could try to unpack the statically linked i386 version of skype in
you home directory and start it out of a shell. This could be a
workaround until you can install the package but I really don't know if
libc6-i386 is needed for the statically linked version too.
http://www.skype.com/go/getskype-linux-static
Yes, I tried that but no go. Error message is a rather cryptic
jonat...@lappy:~/dwhelper/skype_static-2.0.0.72$ ./skype
bash: ./skype: No such file or directory
but that file, skype itself, does exist:

Anyhow, hopefully the maintainers will make the ia32-libs etc
installable with libc6-i386 so I can get skype working.

You want what you want from other people in an easy format so they've packaged it for you. When you're asking others for something, you're the beggar. You can TRY to also be the chooser, but if that were the case, and you were a chooser, then you'd be selecting from several available choices. I don't agree with you, I'm just looking for some people who have the same thinking with me, I'm not begging from them, for they also need my paticipation very much. 1) You're being literal and focusing on exact meanings, instead of interpreting the entire idiom. 2) We all look at our situation and interpret it with us having the highest and best goals. None of us look at ourselves as clearly as those who look from a distance. I sure know my ideal is far from the reality, but I think the meaning of life is to spend some time in realizing my ideal. First, when you look at what's in even just a minimal Linux install, there is no way you're ever going to get through working on more than a few programs in the next few years. Second, when a programmer writes a program, if he has any wisdom (which is knowledge gained through experience, hence the more years, the more experience and the more wisdom), he will use the right tool for the right job. For instance, I need to use mainly Perl and Java, but have used many other languages. I find I can code 5x faster in Perl than Java and about the same, maybe better if I use Perl instead of C++. Hardly any of my Perl code is done as a wrapper for a C or C++ program. It is valid code that does a LOT of work and does it well. Since it's text processing, to do the same work in C or C++ would be a nightmare. If we setup proper C/C++ library for text processing, we can reach the same effect as Perl, why cannot? for any piece of perl code, I believe I'm able to write a piece of C++ code as simple to replace it, on top of a proper library. It's the same for python, java and other languages. I worked on C# for 4 years, it's also a very efficient language, but I can drop it, for I know, C# is just C++ with a good library, the .net framework, but its cost is an additional layer, the .net runtime and its intermedia language. There are C and C++ text processing libraries. They don't have the power of Perl or Python or other languages. C has been around for decades and contributed to and worked on and used by many, MANY programmers. These people have more experience than you or I and their combined experience is enormous. If C was such a great language for doing every thing out there, and we'll use text processing as an example, why haven't these people released libraries that do all that Perl does already? One answer is that good question, why haven't released those C libraries? I will release one in the future, I'm sure I'm able to replace perl by C, including change C a little, but changing C a little is much better than creating a new language like perl. When you get into writing them, I think you'll see. Actually, it's kind of funny to look at this and see a young and inexperienced programmer thinking he's going to be able to do what many, many master programmers have never

Eventually you might find DirectFB acceptable. http://en.wikipedia.org/wiki/DirectFB Lack of XDirectFB in Debian is a limitation for now. thank you, I think DirectFB is the right direction, while X window is a strange way for graphic system. I hope I can find a DirectFB implementation of window system to replace gnome. I'm afraid that you are out of lucks as DirectFB won't help your cause either as there are VERY few programs that support it. I think that there is a media player, image viewer and possibly a pdf viewer, but not much more. You won't find anything similar to gnome unless you start writing it. Most gui programs depend explicitly on xorg calls so won't run without x windows.

Boy, I didn't realize that by junior programmer you meant you were that inexperienced in the field. I don't know if you realize that you've just basically said you are either unwilling or unable to understand the different reasons for different languages. EACH language is a tool, and each one is a DIFFERENT tool with a DIFFERENT purpose. I will give an example to deny your opinion - a DIFFERENT tool with a DIFFERENT purpose Sql is a language for database operation, but what microsoft doing is to use C# replacing sql, by linq. I don't like microsoft, but I like the way they developing C#, the only one language for microsoft will be C#, I guess. The only one language for microsoft is c#, oh wait, its visual basic, sorry wait a minute it's forms for the gui, assembly in the drivers in if you start digging you will find that half the system management is using scripts and batch scripts of one sort or another. Then what's the only one language for linux? I think it's C/C++. I'm afraid you are out of luck. All the init scripts are as the name sugests, scripts (you may get away without bash but you won't get away without sh which is basically simple bash). You probably should compile the kernel as compilation includes scripts (assuming you don't have problems with make files), emacs is out of the question as half of it is writen in elisp (variant of list). Vim may be ok, don't know. You can try dos, but the startup agian depends on batch scripts. OSx likes objectiveC more than c++, but there is also quite a bit of apple script and it's unix behind the scene which means perl, bash, python, etc. It is rarely a whim why a programmer picks one language over another. There I found that it's usually due to a whim and a bunch of buzz words. Usually it's the program you know, but quite often this is due to you picking your initial language to match the programming you like. I also do find that a lot of people, esspecially windows people BTW, tend to be narrow minded and lock into one programming language, usually it's c++ or c#. A lot of times its' the managers who don't know anything about programing that choose the language. are often several, if not many reasons why one language is more appropriate and better for a job than another is. But there's no point in continuing any discussion. You've made it quite clear you're too busy being right to care what anyone more experienced has to say -- unless it's what you want to hear.

So now you have a gateway? What firewall configuration software are you using? What is the output of cat /etc/network/interfaces The weird thing is that with normal booting configuration, pinging INet addresses fails. This seems to be related to the order in which the interfaces come up: doing ifdown eth1 ; ifdown eth1 ; ifup eth0; ifup eth1 causes pings to fail; but if eth0/eth1 are reversed (bringing up eth0 last), or eth1 is simply suppressed, pinging URLs works (i.e. ping www.debian.org). Sounds to me like both are setting a default gw. The last one takes precendence so if you bring up eth0 last the default gw is set to the outside world, if you bring eth1 last the default gw is in the local network and assuming the dns address is not on the same subnet as eth0 requests are going through the default gateway to eth1 which has no idea what to do with them Have you a local DNS server? Regrettably this last does not entirely solve things - for example, I cannot do system updates: apt-get update fails to connect. Error? times out? unable to contact … ?

Without sacrificing eth1? Or at least some better diagnostic[s] to track down where packets are getting lost? Of course, I'd only post to this list after I'd used apt-cache search network test | wc -l and saw that it shows 83 packages which fit that search criteria and see that there is not really anthing useful, ok there is ping, but you've already used that.

We're at the mercy of the package maintainers to at least put some decent search terms in the descriptions and not just copy a paragraph off the upstream website or manpage.

The -bigmem flavour should not be needed unless you have *more* than 4GB RAM, but it's worth experimenting with. Actually if I'm not mistaken more the 2gb or 3gb (not sure about the standard setup). Theoretically standard 32bit can address 4gb but the kernel splits that memory space between userspace and kernel space, classically in a 2gb:2gb split, which leaves 2gb addressable memory. It is possible to set it up in a 3gb:1gb split, but it is not standard. Bigmem uses an extention that allows addressing more memory (I think that it's called pxe). Another option is to use a 64bit kernel, but unless you use a 64bit userspace a few things can cause problems (most things work ok, I think except some modules). The only problem with a 64bit userspace is more memory consuption by programs (about 15%). Performace may also vary, depending on typical usage.

I've only got a passing familiarity with OpenGL, but I'll guess...
If you are doing a screen capture via OpenGL, you'll probably want to create
your own context (with direct GLX calls), rather than using the one provided
by your widgets API (Qt/Gtk). You will probably need to base it off of the
root window.

Everyone will run it eventually. Except older computers and possibly embedded processors, such the ones that power .mp3 players and the like. ARM, Coldfire, SH-1, and so on. Right now, there is no hurry to move from 32- to 64-bit, especially if your machine has 4 GB or less. Or you need the 64-bit architechture itself, for the extra registers, whatnot. Some number-crunching applications can benefit from it. A downside is 64-bits not only allows more memory, it requires it. 64-bit pointers vs. 32-bit pointers. Excuse me, *addresses*. I recommend 64-bits for new installs, but for existing setups, there is no need to update, unless you have specific needs. Mark Allums Oops, make that *3* GB or less. The PC architecture allows more, but while 4 GB fits into 32-bits, the video card and other hardware is memory-mapped into the upper GB, so the 4th GB of physical memory must be remapped above the 4 GB line. In theory, with PAE segments you can address that memory with a 32-bit OS, but in practice, 64-bit is required. It's not so much the video card any more (used to be that the video card was mapped into this space but it was a long time ago in the days of far pointers and memory size less than single digit megabytes). It's the kernel memory that is mapped there. By default the application has a four giga memory space under 32bit, two of which are actually used by the application and two for kernel mode. This is used to reduce overhead during context switching between usermode and kernel mode. You actually need a patch to change this to a 1:3 ratio instead of a 2:2 ratio. The standard recomendation in this case is to use amd64 for memory 2gb. Like you said, theoretically it is possible to solve this differently but it is very inefficient As for other the advantages and disadvantages 1. amd64 has more registers, mostly useful for sse instructions and thus can benefit number crunching applications 2. on the other hand it uses 64 bit pointers (addresses) and thus usually uses about 30% more memory than 32bit applications. This means more pages and thus less spatial coherence which results with less cache coherence, actually hurting performance. So unless you do a lot of sse based number crunching or have more than 2gb ram you are still better off using i386 over amd64 for regular desktop usage 9 times out of 10 at least BTW, you can always install a amd64 kernel with i386 userspace to access more than 2gb for the system (although single applications will still only be able to use 2gb each). As for applications, the only one I'm missing at the moment is a 64bit version of skype (you can still run the static version), most everything else has 64 bit versions I believe (at least things I use) Mark Allums -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.
