I recall that MSWindows used to be and it possible still is rather sensitive with needing the boot flag on its partition. Linux on the other hand is a more advanced OS which does not care where the boot flag is. The NTLDR bootloader is no more since Vista.

I mean use the Windows 7 bootloader as the primary bootloader to chainload GRUB from the Gentoo partition. The MSWindows stays in the MBR as it is now, the GRUB is installed in the Gentoo /boot partition. MSWindows bootloader chainloads GRUB. > Again, the answer's a lemon - suck it and see. > > No offence intended. Thanks, none received. I am not American. ;-) PS.

I do have hald running, but made no special config regarding cdrom
polling. At least not on purpose.
The messages do appear to be continuous. I will execute a reboot soon
but don't want to right now.
Why I'm pondering and following this up, is that I experience a
serious freeze after some unspecified amount of uptime. Mouse and
keyboard become unresponsive... and eventually the OS cannot be
accessed at all.
SSH appears to stop and cannot contact remotely either.
This began happening quite some time ago... on a different earlier
install. I never could see anything in the logs that gave a clue to
why.
I created a script that ran from cron. It pinged a remote host, and
logged a unique easily findable string into the log using `logger',
every 5 minutes. With that I was able to narrow down the time frame
of freeze to within the last 5 minutes (of log lines).
Even then, there was nothing to indicate a problem. This was an OS
that had been running a very long time with upgrade after upgrade.
Though I hated having to rebuild all the customizations etc, I finally
completely reinstalled from scratch hoping to catch the problem with
the shotgun approach.
In that earlier OS there were no log messages regarding hdc being
generated (by the way).
Shortly after completing the new install and a couple of weeks of
getting setup the way I wanted, I began to experience the freezes
again.
I have caught the freeze in the early stages before completely losing
the network when just mouse and keyboard became unresponsive, was able
to ssh in and noticed that restarting hald held off the freeze for
some (again unspecified) amount of time.
So cutting the lengthy narrative down a bit, and briefly put, I'm
looking for anything unusual that is causing this. The hdc messages
is the only odd thing I'm seeing.
Something appears to be jamming up the hal layer somehow, but not
leaving findable tracks. At least not findable by an someone with
many yrs experience with linux but not much real debugging of
complicated problems under his belt.

VERY strange that you don't see pcm as a mixer control...

In particular lxde and xfce4 fly on older hardware and is well received by and large by people wanting lean and mean desktops. The various *box WMs also had decent writeups on getting them running last time I looked. A few eyeballs on those pages and updating them if necessary would not go amiss. Many people would like to have slimmer alternatives to the usual monstrous culprits: firefox, thunderbird, openoffice, evolution. KDE4 does not suit everyone (neither are Ferraris and Toyotas), so while it is important to understand what KDE4 is and what the limits are, and not try to make it something other than what it is, there is definitely room for systems completely devoid of anything from KDE and/or Gnome. -- alan dot mckinnon at gmail dot com

Do you have hal configured to poll your cdrom drive every two seconds, to see
if a disk is inserted? And if so, is the verbosity logging cranked up way
higher than it should be?
I haven't personally had to fix this myself (so can't give pointers on where
to fix it), but it seems to be a common occurrence judging from posts I see
here and at other forums.

If you only do moderate writing SSD are much more reliable. If you do a lot of writing - douzends of gigabyte a day with a lot of overwriting, a HDD might be the better choice.

Mike Edenfield wrote: > I'm kinda stunned that your arguments against D-Bus seems to boil down > to "just use 9p instead" No, we're talking about very different concepts. D-Bus is essentially an generic RPC mechanism (with an asychronous signalling facility). So it allows calling procedures on remote objects sending signals to listeners. IOW: fundamental concept behind GObject, QObject, etc put onto distributed level (but much simpler than CORBA, etc). On the other hand, 9P is essentially just a filesystem protocol which is very well suited for synthetic filesystems. The latter is the key point: synthetic filesystem. Instead of calling procedures, you model objects into directories and files and simply work with common filesystem operations. This is the same idea as behind procfs or sysfs, but on an distributed level. Hopefully, we agree that procfs and sysfs are a simple and easy approach for accessing many many kernel-internal data using very standard filesystem operations. Now imagine we hadn't them, but needed to use separate syscalls or netlink operations. Wouldn't it be ugly ? > given that plumber is a basic element of 9p and > does essentially the same job D-Bus does. No, plumber is an 9P-based service which does the message broadcasting/routing to listeners (easily programmable by an special-purpose language).

Right. Either you use the kernel module (which now is in mainline for quite a long time), or 9pfuse, or one of the userland libraries around (eg. libmvfs). The basic idea behind this all is to use a filesystem as a primary IPC interface. Files dont necessarily mean things stored on-disk, but streams/communication-channels in an hierachical namespace. (eg. /proc or /sys). This way you have a very simple IPC mechanism using the very same semantics as filesystems do traditionally. That's just consequently using the "everything's a file"-metaphor. As everything's a file, all an OS or an distributed environment has to provide is dispatching filesystem operations from client to server, whereever they may actually reside. For example, you can simply mount any Plan9 device via 9P, from anywhere, as long as you get some 9P path there. (BTW: 9P doesnt have the concept of ioctl()s. If some object has more than just a single IO stream, it's modeled as an directory, eg. containing some "ctl" file accepting additional commands, etc). cu -- -- Enrico Weigelt, metux IT service -- http://www.metux.de/ cellphone: +49 174 7066481 email: i...@metux.de skype: nekrad666 -- Embedded-Linux / Portierung / Opensource-QM / Verteilte Systeme --

I had a similar problem with an Audigy (CA0106) card. If depends if you have analogue or digital speakers. If they are analog the S/PDIF slider must be *muted* or there is no sound. This is counter-intuitive since one's first action with Alsa is to unmute everything! HTH -Robin -- -- Robin Atwood.

[gentoo-user] Can't hear anything. :-(
Hi, gentoo, I'm trying to get sound to sound on my new Gentoo box, following the "Gentoo Linux ALSA Guide". Everything seems to be working fine, except no sound is coming out of my loudspeakers. I've checked the obvious things: the speakers are plugged in, switched on and connected to the appropriate socket on my motherboard (the light green one). I have drivers for my motherboard's sound chips compiled into my kernel, and they are correctly identified by alsamixer. With alsamixer I've unmuted various things and turned up the volume. madplay appears to play an mp3 file I have. Just that no actual sound comes out. One other strange thing: the titles under the "volume bars" in alsamixer are very different from the ones in the document: Instead of "Master / Headphone / Tone / Bass / Treble / 3D Contr / PCM", I've got " Master / Headphon / Front / Front Mi / Surround / Center / LFE / Side / Line / Mic / Mic Boos / S/PDIF / S/PDIF D / Beep". Why is this? In particular, I'm missing the "PCM" volume bar which the documentation says is so important to unmute. What am I missing here? Thanks in advance! -- Alan Mackenzie (Nuremberg, Germany).

I have / on ssd, but /tmp on tmpfs, /var on harddisk and swap on harddisk. I don't want to wear it down ... and 40gb is not that much.
