.2.6.28-*.

the good stuff within:

pci/kvm changes (mmap legacy_io support, pci quirks removing; kvm supporting vt-d driver).
ext4/ext3/ocfs2/ubifs/gfs2/nfs mods (e.g.,
ext4dev it's now ext4 (fs/Kconfig, fs/Makefile, fs/ext4/*), so no TEST_FILESYS anymore; error handling control option (i/o operations; buffer write errors don't get detected, if fsync() is not used, iow, determines whether to call printk() or to abort journalizing; however, ignoring will be set by default), (prominently fs/ext4/ext4.h); no HUGE_FILE flag auto-enabled; delayed allocation mode disabled (fs/ext4/inode.c).
default autodetection of a config option for raid configs.

some drivers had been held on place, aka staging.

grab the patch: http://kernel.org/pub/linux/kernel/v2.6/patch-2.6.28.bz2.

.nvidia-96-kernel-source: 96.43.09.

as expected/promised, 71.86.07/96.43.09 drivers are available.
add the following line to /etc/apt/sources.list:
# `"deb http://archive.ubuntu.com/ubuntu/ intrepid-proposed restricted main multiverse universe"'.

some apt-pinning:

% sudo touch /etc/apt/preferences. then, edit it:

"
Package: *
Pin: release a=intrepid-updates
Pin-Priority: 900

Package: *
Pin: release a=intrepid-proposed
Pin-Priority: 400
".

finally, switching:
% sudo apt-get purge nvidia-96-* -V ; apt-cache show nvidia-96-kernel-source -f \.
% sudo apt-get install nvidia-96-kernel-source -t intrepid-proposed -V ; sudo apt-cache show nvidia-96-kernel-source -f \.

_d__k__m__s_ shall do the work, after that. have fun.
optionally, give nvidia-xconfig a try (appending, of course, "Option \"NoLogo\" \"True\", within the `Device' section of your /etc/X11/xorg.conf).

p.s. % glxinfo ; glxgears \. -- : ).
p.s.s. feedback /at/ here.
P.P.S. happy hackin.

UPDATE.01:
# 96.43.09 -> stable repos (currently 400). hope to see that soon.
UPDATE.02:
# 96.43.09 :: 900 ; iow, stable.

.routine intrepid diggings.

## 00.
nVidia:
nvidia-glx-legacy and nvidia-glx in Hardy, the 71/96 (currently 71.86.04 'n' 96.43.05) series (nVidia TNT, TNT2, TNT Ultra, GeForce, GeForce2, GeForce3, and GeForce4 chipsets) of proprietary nVidia drivers, are _not_ compatible with the X.Org included in Intrepid. ; resolution: mesa / no 3d rendering.
nVidia released some (two) betas, working with X.Org 7.4, so... waiting for these packages (http://www.nvnews.net/vbulletin/showthread.php?p=1821020/ - nVidia devs' confirmation).
ATI:
no more support[1] for Radeon 9500 - X600 Series (r300 based chips).
p.s. [1] == Support from the ATI Driver, for Ubuntu 8.10, of course...

## 01.
Audacious 1.5.1 [UNSUPPORTED VERSION] :: segmentation fault ; resolution.01: remove -purge, remove/purge audacious-crossfade or alter ~/.config/audacious/config.

## 02.
xchat 2.8.6 :: chanopt.conf feature. +1.

## 03.
mplayer segmentation fault ; using nv driver (under x).

## 04.
The possibility of $# sudo service < service.foo > [start|stop|restart] \, and $# sudo service < service.foo > status \ will report the state of service.foo (running or not).

## 05.
Nice runlevel layout, making rcconf more easy to use on managing services/daemons.

## 06.
Executable(s) randomize the in-memory location, net.services being compiled as PIE (position-independent executables) (e.g. postfix, openssh, apache2, bind9, dhcp3). +1 for security (vulnerabilities are _harder_ to exploit, on the 2.6-27-7-* kernel).

## 07.
Sun's Java OpenJDK 1.6 included into the main repo.

## 08.
the "CD eject" thing.

so, finally, happy release to you all.

## # _more_ to come. : ). #
n.b. stay tuned! intrepid shall be here.

.intrepid alpha 5.

Among the newest GNOME (2.23.91) with its new features (like the improved File Roller archive manager which now has extra support for ALZ, RZIP, CAB, TAR.7Z) and many bug fixes, official DKMS project testing on Intrepid (useful on third-party drivers updating, on a new kernel core update - highly increased stability/compatibility; less work for you), Ubuntu Intrepid Alpha 5 has began the official evaluation of kernel 2.6.27 (available for install since 28 August - AFAIK) for Ubuntu 8.10; also, the "Last successful boot" implementation (adding a last successful option on GRUB's /boot/grub/menu.lst, each time the boot process is successful - by making a copy of the running kernel), useful in APT's autoremove feature (by making it more safer - speaking of kernels).

.2.6.27 on intrepid.

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the
upcoming Intrepid Ibex 8.10 release.

You can either install the linux-image-2.6.27-* package (currently available for testing),
or wait for the upcoming Alpha 5 (to be released Thursday September 4) for Intrepid, which will contain the 2.6.27 kernel.

Feedback will be apreciated.

.intrepid alpha 4.

Major bug fixes + *the _cool_ stuff*.
... Such as:
## # 1

## 1.0
# A location for _human_ users to securely store data using filesystem encryption.
# ~/Private directory, permissions maintained at 700.
# Mount cryptographically (ecryptfs) on top of ~/.Private (also permission 700).
## 1.1
# Hook PAM to use login password to unwrap a mount passphrase.
# Automatically mount and unmount ~/Private on login (console, ssh, gnupg, desktop, etc).

## # 2
## 2.0
# A temporary password-less user account with restricted privileges (the so-called\
# "guest account").
# Comfortably for a quick sharing of your desktop/laptop (an email check, a surf station for guests, etc).

## # 3
## 3.0
# Network Manager 0.7.x, which will work with any card that properly supports wireless extensions.
## 3.1
# New (management) features: PPP and PPPOE connections, routes for devices, static IP configurations, 3G connections, system wide settings - no\ # log in needed in order to get a connection, and also multiple active devices.

Oh, and 2.6.26-5.15 kernel : ).

.intrepid alpha 2.

Ubuntu 8.10 (code name Intrepid Ibex), scheduled for final release on October 30th 2008 is moving forward to the absolute greatest software of the Open Source Community.

The Intrepid Ibex Alpha 2 (July 10th), is the second alpha release of Ubuntu 8.10, which, along with the very new improved features (package merge from Debian, also with brand new packages and heavy upgrading of the existing ones, Xorg - X11R7.4 with new and upgraded modules, apps/utils/drivers/libs, featuring xserver 1.5 - currently RC5 ), runs on 2.6.26-3.9 kernel, based on 2.6.26-rc8 (2.6.26-rc9 soon). The new kernel, announced on 13 Jul 2008, by Linus Torvalds, along with its stable release has many improvements from 2.6.25 (including EXT4 new - experimental - features, built-in support for remote KGDB debugging, new KVM ports and USB Video Class driver, build-in-kernel memtest, /proc/pid/mountinfo, read-only bind mounts, wireless mesh networking support, security= boot parameter, and much more stuff), along with lots of driver additions and some architecture-specific enhancements. Oh, let's not forget about the Kernel Hacking make options, where you can configure and test some of the new features.

However, there still is massively increased video drivers instability, so, while this still is an alpha release, you are advised not to install it on production machines. In the meanwhile, you can report bugs through the Ubuntu bugtracker. : )

.eee or electronic easter eggs.

*wandering* around some of my beloved systems/programs/commands/libraries/routines, I have discovered and read about a lot of hidden features/arguments/options (aka easter eggs).

## # Deprecated:
#
# Running 'whois the devil' or 'whois the antichrist' on Ark Linux.
#
# 'emerge moo' on Gentoo.
#
# 'who is god' on Gentoo.
#
# 'man tunefs' (look under "BUGS" header) on Solaris.
#
# 'make love' on Solaris.
#
# 'man c' (Coffee Distributor) on Debian/Mandrake.
#
## # .

## # Super Cow Powers, on Debian:
#
# 'apt-get --help'. At the end, apt-get shall print "This APT has Super Cow Power".
# Now, do the same with aptitude.
# 'aptitude --help'. This time, it shall print "This aptitude does not have Super Cow Powers".
# OK now. So you're wondering what's with this Super Cow, isn't it?
# Just execute 'apt-get moo'. Nice, isn't it? Hackers' love for cow is materialized in a cool easter egg. : ).
# But, what's the thing with aptitude, which doesn't have Super Cow Power?
# Again, 'aptitude moo'.
# To figure it out, increase the verbose level (appending a '-v'), until it stops telling new things. Enjoy it!
# PS: This is a reference to Antoine Marie Jean-Baptiste Roger de Saint-Exupéry's "Le Petit Prince" (The Little Prince).
#
## # .

## # Into the void:
#
# GAG: open a shell and type 'ddate'.
#
# In a shell, mistype ls (as sl)... and see the results.
#
# While at a console, type in: 'grep -r /usr/src/*'.
#
# 'grep LINUX_REBOOT_MAGIC include/linux/*.h' - parameters used in reboot() system call (like 369367448, or 0xfee1dead). Convert the\
# output using perl, e.g. 'perl -e 'print localtime(). "\n";'' (those are important dates for Linus Torvalds). : ).
#
# 'zgrep "The.*Release" /usr/share/doc/dpkg/changelog.Debian.gz' in a shell. Obviously, Debian-related.
#
# '/usr/libexec/redhat-credits' on Red Hat.
#
# In vim, type :help 42 (This is a reference to "The Hitchhiker's Guide to the Galaxy").
#
# "You don't exist. Go away." message, when invoking UID doesn't correspond to a valid user, or if the session isn't properly registered in utmp.\
# (find it out by 'strings /sbin/shutdown' - oh ,also there, "Oh hello Mr. Tyler - going DOWN?"; reference to Aerosmith's "Love in an Elevator"\
# video.).
# BTW, "Oh hello Mr. Tyler - going DOWN?" can be seen on the logout of a 'tyler'-called user name (e.g. at reboot/shutdown).
#
# Once in /var/named, open localhost.zone and localdomain.zone in a text editor.
# There, related to 127.0.0.1, somewhere the serial is set to 42; also commented ("(d. adams)") (Reference to Douglas Adam's book series
# The Hitchhiker's Guide to the Galaxy, which is famous for stating that the answer to Life, the Universe, and Everything is equal to 42.).
#
# 'cowsay -f foobar !#' in a shell, foobar == any.file.from /usr/share/cowsay/cows/.
#
# 'ar r God' in a shell.
#
# 'nice man woman' in a shell.
#
# '^How did the sex operatino go?^' in a shell.
#
# If you boot a SuSE disc, after the greeting the bootsplash, hit F5.
#
# Give it a try: 'man grep | tail -n7'. Ubuntu Specific.
#
## # .

## # GDM:
#
# type "Start Dancing" into the username field (classic gdm only).
