Re: EM64T compiling options?
Hi, I'm migrating from an i686 to an EM64T machine (Intel core 2 quad) and I'd like to know whether there are specific options that I can pass to gcc for an optimization of my code or if everything is blindly set up. How would I manage the 4 cpu cores if I was to write in assembly? GCC has a lot of optimization/architecture flags. Just have a look here [1]. However, this won't make your software use the 4 cores. You should use threads or multiple processes with IPC. I don't know what you want to do but I think you should forget about writing in assembly and use an higher level language. You probably don't need assembly at all. Moreover, higher level language have sometimes concurrency and synchronization facilities which will help you getting the most of your 4 cores.

Re: How would I get debian unstable?
Also, why did you people choose to use debian? Is it just better than other distributions? I don't know, I have never used anything else (besides short adventures with Gentoo and Ubuntu and a few more live CDs). I switched from Gentoo to Debian on my laptop 6 months ago. I used Gentoo (and I'm still using it on servers) for many years. I learned a lot about GNU/Linux this way. I liked to test the latest software releases, choose the dependencies in really need, test some unusual compilation flags, etc. Now that I'm a bit older, I don't want to spend so much time in setting up my system. I want something that works (quite) out of the box. Moreover, compiling every single piece of software is a time-consuming task. So I wanted to try something else. One of my friend is a Debian maintainer and it convinced me to give it a try. I'm quite happy with my Debian unstable. I have a 6 months old laptop so I had few problems at the beginning with bad hardware support. But now, everything is working as I want to. I regret that some software takes a long time to come into unstable/experimental (e.g. Gnome development release). And I find that it is easier to create Gentoo's ebuilds than Debian's packages. But I still have to learn a lot about Debian. I'm using Ubuntu at work and on my girlfriend's laptop. This is probably one of the best desktop distribution I think. And I don't see so much differences compared to Debian. The only reason for me not to use Ubuntu is, as you said, It seems like you people are elite linux users, I don't want to use the same distribution as my girlfriend or a distribution that my mother could install herself :D I still haven't found a distribution that makes me 100% happy. But I'm really happy with Debian at the moment. In a way, Debian offers more choices and doesn't force anything on you which you don't strictly need. On the other hand this means you have to make more choices yourself which is hard if you don't understand your options in the first place. Gentoo offers even more choices. So if you have time and want to learn more about a GNU/Linux system, give Gentoo a try. Moreover, the forums and the documentation are awesome.

Re: Unable to hear audio
Hi Vincent, I only found references on how to compile fresh kernel sources but nothing specific to making changes to pre-existing kernels. Is it the same or are there any specific docs I could look at? I would do this like that: 1/ zcat /proc/config.gz > /usr/src/linux-source-2.6.x/.config 2/ cd /usr/src/linux-source-2.6.x 3/ make oldconfig 4/ make menuconfig 5/ make-kpkg --initrd --rootcmd fakeroot kernel_image 6/ cd .. 7/ dpkg -i linux-image-xxx.deb 8/ reboot Replace the "x" characters with the correct values ;) You will also need to recompile the external modules if any.

Mute key not working anymore on T61
Hi all, Since a few days (weeks?), my mute key does not work anymore. Volume up and down work as expected. xev just says nothing while pressing this key. I reported this here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=460564 However, I can't remember if the mute key used to generate an ACPI event or was monitored by thinkpad-keys!? Dear Lenovo T61 users, do you have a working mute key under unstable? Thanks, Cyril Jaquier -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

Re: which kernel to use on 64 bit hardware and 32 bit userland ?
As i say, running amd64 kernel have problems - suspend resume does not work, nvidia module dont compile Suspend to RAM works perfectly on my T61. Nvidia kernel module compiles just fine with 2.6.22, 2.6.23 or 2.6.24-rc5. I use my own compiled Debian kernel on amd64 unstable.
