However, Carsten said: the kbd layout (xkbswitch) module changes layout by executing the setxkbmap binary. e will output to stdout what it runs with SET XKB RUN: So, is it an xkb problem? I can change the layout if I run manually setxkbmap gb, so what is the cause of this? I don't really understand ... :-( That stuff is murky in my world :-( I've only ever used US keyboards so never change layouts and when I read up on how it all works I get ... mighty confused But here's my understanding of how it hangs together: xkb* is one app that deals with this, KDE has it's own app, so does fluxbox and various other WMs too. many people report that e17 doesn't work properly right now but KDE and fluxbox do. So logically speaking, setxkbmap is the app that is broken whereas the layer beneath it is fine (otherwise fluxbox couldn't work properly) -- Alan McKinnon alan.mckin...@gmail.com

Reading install HOWTO docs for Nagios is a useless activity. You will almost always end up finding a doc that describes a different version to what you use, and on a different system. I prefer to just understand what Nagios does and how it's set up on my machines, then read the plugin's code, that tells me how to install and use it. First thing to understand is what Nagios is, and it's not a monitoring tool! That just happens to be the problem people use it to solve. Nagios is a state tracking and notification engine. It compares the state of something now to the state it was in 5 minutes ago and if things changed it sends a notification. All the monitoring stuff it can do is actually plugins and little scripts sitting in various places. To check the state of a ping test, Nagios runs a ping test script. That's if Nagios does the test itself, you can also have plugins feed information back into Nagios. Then there's the tests you want to do that Nagios can't see directly, like load on a host. You have to log into the host to see that (which is dangerous). So there's a daemon running locally on the host called nrpe, and Nagios queries this daemon asking it for results. The results are the state that Nagios is tracking. Like I said, script authors like shoving their scripts in any old damn place and this is a PITA to sort out when it goes wrong. Rather just decide for yourself where things need to go and put them there yourself. There are so many things Nagios could do much better than it does, but the maintainer is highly resistant to adding any features that he doesn't use himself. So there are many forks around, why don't you try one of those? Some of them are rather well coded. There's many, and searching Google for Nagios forks: will turn up useful projects. -- Alan McKinnon alan.mckin...@gmail.com

Similar to your setup, back when I used blackbox, emerging bbkeys would pull in blackbox as a dependancy. My setup takes a little a little setting up, but saves a lot of work when setting up a new kernel. I run with 2 kernels available... 1) Production 2) Experimental Sometimes they're identical.

It does the make and overwrites the previous Experimental kernel, and runs lilo. It does not touch Production. After the Experimental kernel has been running trouble-free for a while, I promote it to Production, by running ../promote from /usr/src/linux. This copies the experimental kernel over the production kernel. At this point, they are identical. Having a previous working kernel to fall back to has saved me on a few occasions. Note; on a brand new install, lilo will come back with an error on the very first run of ../makeover, because there is no Production kernel found. The first time you run ../makeover, run ../promote immediately afterwards. This copies the Experimental kernel to Production, and satisfies lilo. -- Walter Dnes waltd...@waltdnes.org We are apparently better off trying to avoid udev like the plague.

Yes, no, improved virtual memory performance. +1 SSDs aren't cheapo SD cards, they are meant to be written to. A storage device that broke if you tried to store stuff on it would break trading laws in any civilised country. +1 Even if the SSD failed inside the 2 year guerantee time - you'd get a new one for free. And in 2y you'll need the new mobo anyway - so there's nothing to loose. -- PGP key @ http://pgp.mit.edu:11371/pks/lookup?op=getsearch=0x837FB8B5BB9D4887 # gpg --recv-keys --keyserver hkp://subkeys.pgp.net 0xBB9D4887 signature.asc Description: OpenPGP digital signature

And about portage: you write in your portage tree not nearly as often as in /home. SSDs don't die as quickly as you think. The most important thing about wear leveling is to keep 10% free disk space in all partitions and enable discard. You'll be fine then. -- PGP key @ http://pgp.mit.edu:11371/pks/lookup?op=getsearch=0x837FB8B5BB9D4887 # gpg --recv-keys --keyserver hkp://subkeys.pgp.net 0xBB9D4887 signature.asc Description: OpenPGP digital signature
