Thanks. What I still wonder: * I copied my gentoo over while the ssd still was on firmware 02HA, I upgraded to 02HD (latest Intel-firmware for the X25-M G2) with the os already on the drive. Does that somehow make a difference to data written *after* the upgrade? I just wonder if I should somehow restart from scratch with the new firmware, just to "do it right" or "get the optimum". * The new firmware supports TRIM. As far as I understand, the block-layer in the linux kernel 2.6.32 does not yet support it, correct? Any way to use that command with my current 2.6.32? ext4 supports it (I use ext4 for the root-partition) but I am not sure if that is enough when libata does not? When I google I get different results, some saying the kernel supports TRIM since 2.6.28 ... Hmm, good info here: http://www.linux-mag.com/id/7272 says: > So at the moment, ext4 informs the block layer that blocks that > belong to deleted files can be discard, so once TRIM-capable SSD’s > become available, and the Linux block layer actually sends the TRIM > command to the hard drives, everything will be all set to go.

It's a bootloader, not a OS, and doesn't mount anything. It just reads data directly off disk volumes and (sometimes) has drivers to interpret the raw data. When you say "root" that can only make sense in the context of an OS that uses a "root", so I interpreted it as such. grub is installed wherever you installed it. You can put it on any arbitrary drive you feel like, or even in the first sector of any arbitrary partition if the drive supports such. All you have to do is tell grub where it is. Now, that introduces a wrinkle. On a PC, the BIOS does not support stage 1 booting off a partition. The stage 1 code MUST exist on the MBR of a DRIVE (blame msdos for this stupid idea) so you want to install grub to /dev/sda or (hd0) I strongly suspect that you are conflating the operation of a bootloader with the OS. At boot time Linux conventions have no relevance whatsoever and are not valid, as Linux is not running yet. grub Boots Linux, it is not Linux and does not work like Linux. Much the same way as a starter motor starts a petrol engine but a starter motor is not a petrol engine and does not work like one. -- alan dot mckinnon at gmail dot com

[gentoo-user] The Great Macbook Update 2: How to brace for xorg
Hi, Second thread of help with my Macbook upgrade of essentials which I don't upgrade since a long time. Now I have to prepare to jump from xorg-1.3 to xorg-1.6. I've seen already there are a lot of horror stories in the mailing list and a lot of weird instructions about hal, evdev etc. Before starting, I have some pre-emptive question: - Is using hal for xorg necessary? - If I want xorg to use the same old config files of before, is it enough to compile with -hal ? Is there a way to tell xorg "dynamically" to use hal or not, so that I can check without recompiling but just by restarting X? - I have the keymap (an Italian Macbook keyboard) customized in the , so that, for example, apple key works as Alt-Gr. To keep such customizations on (which, I admit, I don't remember well where they are, but maybe someone of you does! it was in the Gentoo Wiki but now I see the relevant part is no more), is it again good to let xorg use xorg.conf? - Anything else I should be aware of, like stuff to put into xorg.conf before trying to restart X? Thanks! m.
[gentoo-user] Clean shutdown of laptop possible after migration to KDE4?
After migrating to KDE4 it seems like the laptop just dies when the battery becomes empty. In KDE3 I could set klaptopdaemon to warn when the estimated remaining battery time is 15 minutes and begin a clean shutdown when it is 10 minutes. It worked very well. Is it somehow possible to get a clean shutdown in KDE4? I do not want to loose a filesystem because of it.

Willie Wong wrote: > Those are ANSI escape codes. My google-fu is not up to telling me how > to set xconsole to ignore them, but it seems possible that xconsole > just cannot handle ANSI codes? Yes, that's what I was afraid of... However, it seems many people uses xconsole a bit differently by creating a /dev/xconsole pipe (fifo) and getting syslog to pipe information to that and letting the program xconsole to read from that fifo (xconsole -file /dev/xconsole)... I found this: http://www.linuxfromscratch.org/hints/downloads/files/xconsole_setup.txt > A workaround may be to set RC_NOCOLOR="yes" in /etc/conf.d/rc That may work, but I upgraded X yesterday and the start order of xdm has changed (previously it was started right after networking, IIRC); now it starts right before "local". My main interest in xconsole was to see if ntp-client was started correctly and since the new order displays ntp ok/nok on the console before xdm starts, xconsole seems a bit redundant... Thanks anyway! Happy new year! Best regards Peter K

[gentoo-user] Installation (or not) of Perl Getopt::Long
Hey, Gentoo,
I'm just attempting to learn a little Perl and write a little Perl program.
I have been experimenting with the Getopt::Long module, which seems to be
working fine, but I'm considering Getopt::Tabular instead.
So I thought I'd search portage for "Getopt", to see if that is readily
provided by Portage, or otherwise which modules are:
$ eix -c -C perl Getopt
[N] dev-perl/Getopt-ArgvFile (1.11): This module is a simple supplement to
other option handling modules.
[N] dev-perl/Getopt-Long-Descriptive (~0.083): Getopt::Long with usage text
[N] dev-perl/Getopt-Mixed (1.10): Getopt::Mixed is used for parsing mixed
options
[N] dev-perl/MooseX-Getopt (~0.26): A Moose role for processing command line
options
[N] perl-core/Getopt-Long (2.38): Advanced handling of command line options
Found 5 matches.
$
Yet none of them, not even the Get::Long package that I've been experimenting
with, are installed on my system:
$ eix -c -C perl Getopt -I
No matches found.
$
Can anyone explain, please, why this appears not to be installed? Yet how it's
working just fine?
It looks like a simpler options parsing module is installed, but not this one:
$ locate GetOpt
/usr/share/man/man3/Tcl_ChannelGetOptionProc.3.bz2
/usr/share/doc/perl-5.8.8-r8/html/lib/Pod/Perldoc/GetOptsOO.html
/usr/lib/perl5/5.8.8/Pod/Perldoc/GetOptsOO.pm
$
Further evidence that Getopt::Long seems to be working on this system is that
it's used by get_iplayer, which has been working well on this system for the
last 3 weeks or so:
$ grep -i Getopt `which get_iplayer`
use Getopt::Long;
search => [ 1, "search=s", 'Search', '--search ',
"GetOpt compliant way of specifying search args"],
use Getopt::Long;
# Build hash for passing to GetOptions module
Getopt::Long::Configure("bundling");
Getopt::Long::Configure("pass_through");
Getopt::Long::Configure("no_pass_through");
return GetOptions(%get_opts);
$
get_iplayer can be examined at http://linuxcentre.net/get_iplayer/get_iplayer
in case I'm misunderstanding its usage.
I feel really dumb - there must be something simple & logical that I'm missing
here.
Stroller.

[gentoo-user] pxe + initramfs
All, I have been experimenting heavily with netboot (PXE booting). When I go to boot the Ubuntu LiveCD via the network I have to set up an NFS share and export it with the content of the LiveCD so that the kernel can boot from it. However, when booting the Gentoo LiveCD from the network, everything seems to be downloaded as one large initramfs image that is then extracted and used to boot. i.e., no NFS required. How would I go about taking a LiveCD and packing it into a LiveCD so that I don't have to set up NFS exports for all the other Linux distributions? Thoughts appreciated. -j

Ok, I updated, and (miracolously enough) xorg 1.6 + hal/evdev mostly works! Only thing I have to put back in shape is the keyboard mapping. I have seen how to force hal policy to use the IT mapping, but I lost most customizations I needed: - key F11 mimicking the middle mouse button - apple key mimicking Alt-Gr and I don't find much information on how to do this with HAL. Any hint? (Oddly enough, one of the past customizations I had, key F12=right mouse button, still works.) Thanks, M.

Further update: I am trying with xmodmap, but it seems it works in some cases and others not (notably GTK applications ignore it, while KDE apps use it). I've put xmodmap lines in my .xsession, kdm config, and I have identical xmodmap both in my home and in /etc/X11, to no avail. Even if I run xmodmap $HOME/.xmodmap from a terminal and then I start some gtk app, this ignores the xmodmap. Any hint? Thanks and (I forgot) hope you had a merry Christmas! m.

I would think on something like this (untested): The command line would be BackupScriptName FromDirectory ToDirectory #! /bin/bash FROM=$1 TO=$2 cd $FROM for i in * .??* do if [[ -d "$i" ]] # is it a directory? then # yes, it is a directory if [[ -e "$TO/$i" ]] && [[ -d "$TO/$i" ]] then # on the TO side, the name exists # and it is a directory cd "$i" # just to show something pwd # calls recursively this same script $0 "$FROM/$i" "$TO/$i" cd .. else # didn't existed yet on the TO side, # so copy everything cp -a $FROM/$i $TO/$i fi else # it is a file, not a directory if [[ -e "$TO/$i" ]] then # the file already exists # do something to compare the files, like: # gets size from "ls" result SIZE1=`ls -l "$i" | cut -d" " -f5` SIZE2=`ls -l "TO/$i" | cut -d" " -f5 if (( $SIZE1!=$SIZE2 )) then # size is different, so copy the file cp -a "$FROM/$i" "$TO/$i" else # more tests for differences other # than size, like date/time # or even MD5SUM fi else # file doesn't exist at the "TO" side cp -a "$FROM/$i" "$TO/$i" fi fi done Hope this helps Francisco After learning a little about scripting I'll give this a once over and see what I learn. Right now, it's like. . . huh. lol Thanks. Dale :-) :-)

(In truth NR_UARTS=2 is the proper value.) Using MAKEDEV, I can manually create ttyS0 thru ttyS3. Running "stty -f /dev/ttyS? -a" indicates that ttyS0 and ttyS1 are fine while ttyS2 and ttyS3" gives: stty: /dev/ttyS2: Input/output error stty: /dev/ttyS3: Input/output error Regards, David
