I've never looked at Gentoo, basically because from what I've read it appears
that it would be *way* more time-consuming. In terms of other choices, I picked Debian
since an awful lot of what else was out there was derived from it. Now I'm not so
sure of my choice. I *did* feel that it was a good idea to get acquainted with some
distro that used a package manager, so Debian seemed the logical choice.
I'm used to booting into a textmode console
on my machines, and doing
"startx" to get a GUI going. The default here seems to be to boot into
the GUI, and I don't recall being offered a choice about that, either.
I know how to go in and fiddle with inittab, but now I'm reading that
this setup uses something else entirely, so I've gotta figure that one
out too. I'm also used to being able to log in as root, and use a GUI as
that user, and that hasn't worked out as well as I'd hoped either. At
this point I can select a number of different desktop environments with
the GUI login screen as a regular user,
The user-friendly distros' installers all default to providing a GUI login
manager. Main exceptions I expect would be Gentoo and Slackware. The old way of getting started without any GUI login
manager for most distros
(Debian and its derivatives excepted) was through inittab setting something
other than 5 the default runlevel line. In distros that replaced sysvinit
with systemd (e.g. Jessie) the new default configuration for GUI login
manager is found thus:
# systemctl get-default
Wow. Typing systemctl by itself sure brings up a lot of stuff... :-)
I guess I need to get acquainted with this bit of software now, as opposed to simply
going in and editing a text config file in /etc like I'm used to doing. Lots of
complications there...
which will output
graphical.target
It did.
To by default stop init prior to X startup, do
# systemctl set-default multi-user.default
I'll try that just before I'm ready to reboot the system next. Mostly I just
leave it running...
However, as with sysvinit, as with all rpm distros
with which I am familiar,
all the above can be disregarded, and yet not have X automatically start,
simply by including a 2 or a 3 on the kernel's cmdline in the bootloader
stanza you use. Debian and its derivatives (e.g. *buntu) using sysvinit
differed from rpm distros by including X autostart in runlevel 2 and not
defining any additional startups in runlevels 3-5.
The bootloader is another issue. I'm used to LILO, not GRUB. So I have more to
learn here, too.
but logging
into a text console as root and then doing startx I am stuck with
Xfce, which I find limiting.
When I've found myself up against failure of cmdline arguments to startx to
get the WM session I want, I start the GUI login manager (usually KDM3 or
TDM) and login selecting some other WM, which in some situations became the
new default used by startx after login manager shutdown. In openSUSE, changing the system level default WM
session defined for the
login manager has up to now at least been via /etc/sysconfig/windowmanager.
That file doesn't seem to exist here. There's a /etc/sysctl.d directory, and a
/etc/systemd directory, a lot of stuff to sort through.
Other distros control it someplace I never seem to be
able to locate.
That's one of the things that drives me nuts with regard to this stuff. Lots and lots
of complications, and it's not apparent to me why they changed things to be that way,
what the advantage is.
I know at some point in time, user-level control could
be via ~/.dmrc specifying
something other than "default" from among the content of usr/share/xsessions.
I think user-level selection may be something alternatively available via
~/.xinitrc, but I don't recall ever trying without tripping over other problems.
Yup!
Try looking at
man systemd.directives
which seems to refer mostly to a whole LOT of other man pages...! Almost 5000 lines
worth, "contains 1621 entries in 14 sections, referring to 177 individual manual
pages". Wow.
So at this point I need to resolve getting it to boot the way I want it to, being able to
select which WM I want, finding out why my printer won't duplex when it does from
this laptop, and installing TDE when they get around to that new release. Among other
things...
