I may be really out of the loop or old-fashioned, but what went wrong with the old SysV init scheme? SysV inhereited the init scheme practically in toto from what was created for the intermediate SysIV version that was intermal to Bell Labs. SysIV got used for a few projects, and it was a major improvement over the SysIII scheme. Those developing the SysIV/SysV init scheme tried to anticipate future extensions (especially dependency problems) even to the point of ashing Murry Hill to make chenges to the shell to make some "magic" easier. [Specifically the use of shell exec for input/output file descriptor changes.] [Disclaimer: I was working a Holmdel with a SystemIV based project as a contractor and was involved in some of this work.] >From what has been happening with the systemd stuff, I do not see what advantages it really offers over the SysV scheme and its successors like OpenRC.

[gentoo-user] Notes for GNOME3 users who miss a desktop pager.
I've migrated my desktop to GNOME3, and miss a log of functionality. Among the most annoying missing parts for me is a non-dynamic set of virtual desktops and a pager applet to go with it. I have found that the x11-misc/ipager app to be a useful replacement along with gnome-tweak-tool. The gnome-tweak-tool allows setting non-dynamic desktops, (Shell | Dynamic workspaces -> Off, set the count of desktops you want.) The ipager app can then be emerged and configured. Here is my ipager.conf file: --- icon.spacing: 5 icon.min_width:24 icon.max_width:48 icon.min_height: 24 icon.max_height: 48 icon.maximize_threshold: 0.9 # # IPager window position # ipager.window.x: 1400 ipager.window.y: 860 # should IPager starts in slit? ipager.in_slit: no # # display_sticky_windows: no display_shaded_windows: yes # [ yes | no | mouseOver ] display_window_icon: mouseOver # # Button to switch workspaces # # # [ left | right | middle | any ] # or # set of buttons like: #left, right #middle, right # switch_workspace.button: any # mouse.scroll.up: nextWorkspace mouse.scroll.down: prevWorkspace # # Delta (in pixels) # # when an workspace icon changes its size # IPager compare new values and previous. # If they differ less then 'zoom.recreate_icon_delta' then # IPager continues to use an old icon and just zoom it. # If the sizes differ more 'zoom.recreate_icon_delta's value, # then IPager creates a new icon picture. # it is not very efficient to create icons often. # zoom.recreate_icon_delta: 0 # Defines style of zooming icons. Should an icon spacing be expandig or # an active workspace icon lays over other (cross them)? # # [zoomAndExpand | over] # zoom.type: over display_workspace_number: no workspace_number.color: #00 ttf_font_path: /usr/share/fonts/TTF ttf_font: Vera/14 # # Background image for IPager window # #ipager.background.image: /path/to/image.png # # Colors (#RRGGBB) # ipager.background.color: #00 ipager.border.color: #00 workspace.background.color: #C0 workspace.border.color: #00 active_workspace.background.color: #00FF00 active_workspace.border.color: #FF window.background.color:#A47D73 window.border.color: active_window.background.color: #F09029 active_window.border.color: #FF selection_color: #FF0001 This puts a static pager bar in the bottom-right of my desktop with a cool blue feel. This spot is below where I stash the GKrellM panel. It is not the most convenient configuration file, but it also has not been worked on since Sep 2008. You can also add ipager to the gnome-session-properties set. The program live in /usr/bin/ipager use "-c /home///ipager.conf" with the program.

ROFL Dale :-) :-) grub2 is a completely rewritten animal, so it is *different* grub2-install /dev/sd?? is the incantation to put grub2 onto the selected boot partition. Then /etc/default/grub grub2-mkconfig -o /boot/grub2/grub.cfg is the incantation for making the basic configuration. If you have multiple installations on disk, emerge "os-prober" to bring in the detection of "foreign" operating systems. This creates the grub.cfg file, which prominently features a "DO NOT EDIT" warning at the top of the file; rank beginners are advised to edit /etc/defaut/grub if that can make the changes you want, but more advanced users can edit the grub.cfg to achieve desired results. For example, my grub.cfg has the default entry for my preferred OS to boot, and then has entries that bing in other configuration files for various other situations. I've got two Gentoo collections, the Fedora collection and the Windows7 config. the grub2 "info" pages are complete but a little dense and not as well organized as they might be. Good Luck. -- G.Wolfe Woodbury

Most of the binary based distributions have tied their stars to the
major desktop
environments. [For example Fedora is heavily tied to RedHat and the GNOME
desktop, and many RedHat employees are major GNOME developers.]
Fedora/GNOME is very nice for modern hardware and mostly "just works"
because
a lot of effort goes into testing each major release. But the GNOME
philosophy has
become one of hiding the inner workings of GNU/Linux in much the same
manner that
Microsoft hides all the innards of Windows. But Fedora is also the most
'bleeding" edge
distribution, getting the latest and greatest every six monthe or so.
Debian and Ubuntu are also dedicated to producing "desktop ready"
distributions
that hide everything under the hood. The try to provide a more stable
environment as well.
All the binary distributions will have trouble getting the hardware
environment correct.
They just can't move fast enough to deal with the latest and greatest,
or even the tried
and true older stuff. Their Linux kernels have to try to please
everybody and deal in
a reasonable manner with what comes from the computer system makers.
This requires
them to put everything (and the kitchen sink!) in the mix, and hope it
holds together.
Gentoo, encouraging the building of a customized kernel for the hardware
being used,
gets the advantages of clean and lean and best speed available.
Gentoo has become my favorite distribution since it is the most
customizeable and doesn't
force the users to accept too much crap along with the most useable
bits. The documentation
provides relatively clear explanations of "why" in addition to the
"how" The Gentoo Handbook
is one of the most accessible install documents around.
I've been using UNIX since 1977, and Linux/GNU from its invention.
Gentoo provies the
right balance between having the good stuff easily installable, and
being able to configure
exactly what is wanted.
Have fun with Gentoo.

Grub2 grub-mkconfig os-prober method recognizes grub legacy configs and builds proper menuentry stanzas as needed. I'm using multiple discs for booting my system. The first drive (BIOS default) is a Win7 native, but I use the BIOS "boot menu" options to usually boot grub2 from another drive.

The bzImage is a vmlinuz (or vmlinuz) image, and is what grub2 expects
to use with a "linux" kernel definition.
I usually copy the bzImage to a file named "gentoo.XYZ" where the XYZ is
the kernel version number. I'm not sure if
grub-mkconfig is yet smart enough to figure it out completely, but I've
been using grub2 with my gentoo partitions for a while.
Certainly, grub-mkconfig in fedora recognizes the gentoo disk properly
as another linux installation (via the os-prober) and
builds menuentries for them. It may just be reading the grub2/grub.cfg
file I wrote.
One thing is certain, grub2 doesn't have to have all the scripting and
rigamarole that fedora and GNU put in via the grub-mkconfig
command, a simple config file will work as well. GNU has grub2 in the
RC1 phase right now and I've built it under fedora and gentoo
and use it. I've gone from using a grub2 cdrom boot to using the BIOS
boot menu device select to control whether I'm going into
Linux or Win7 (Win7 is on the default device and grub2 for fedora and
gentoo are on other discs.)
I'm using a shared /home partition with slightly different uids for each
system, but a common "username". Each uid homedir
contains native dotfiles for a variety of services and some symlinks to
a common set of {Documents, Downloads,Public,Pictures,
and public_html} directories.

Thanks for the ideas, Mark Many of the cheap KVM models do, indeed, mess up the EDID data coming from the monitor. I suspect that this is from old design specs that have too much pull-up/pull-down on the EDID lead since the boxen haven been re-engineered for newer, higher resolution and higher speed monitors. I have had problems specifically with the BELKIN KVMs. It may also be that the video drivers for Linux are just enough different (necessarily) from the MSFT drivers to not reliably sense the EDID return signals.

[gentoo-user] GDM kbd/mouse lockup after emerge --update on a stable amd64 platform - need hints to cure
I did: emerge -va --update --deep --newuse @world on a stable gentoo amd64 (multilib) system after switching the profile from "desktop/gnome" to "desktop" and adding qt4 and kde flags to make.conf. [I wan to add a few kde apps to the mix, but not everything.] Since then, I get a keyboard and mouse lockup when gdm starts. and can't login graphically or switch to a text console. I'd rather not do a complete re-install on that instance, so some clue as to where to look for problems beyond the obvious dmesg and boot info. I do get a "dmeventd" failure to start, so lvm-monitoring fails to start (even after a re-emerge of lvm2) but don't think that as anything to do with the X lockup. Startx from single user mode also causes a kbd/mouse lockup. I've verified that the kernel has the proper event configuration.
