I'm too stupid for firewalld
by Valent Turkovic
I feel really stupid because I don't seam to be able to operate new
firewalld on Fedora 18. I'm Fedora user since FC6 but this is beyond me...
I tried adding ssh port and 4040 tcp port to services list (Subsonic
server) but not Subsonic server or ssh are accessible. I tried disabling
whole firewall, still not accessible...
Only uninstalling firewalld did the trick.
So I hope there is somebody more inteligent than me to show me how to
operatate firewalld.
I'm not stranger to iptables, so I'm willing to go full manual mode if
needed be, just point me in the right direction because I'm definitely lost.
Cheers,
Valent.

Gnome 3 with a splash of Awesome
by Noah Cutler
After having sat on the fence with Fedora 14, fearing the worst in making
the switch to Gnome 3, I must say, with Awesome for the WM, I am perfectly
fine with Gnome providing the goods under the hood.
xcalib is quite nice as well for inverting screen color (i.e. no more
glaring white background to look at in the evening).
Lot to learn here, Awesome seems complex, enjoying layout toggling,
max/min, %window size +-, etc.
Good stuff, Fedora 18 blazes on Dell M4700 woohooo ;-)

Removing nVidia
by Joe Zeff
Right now, my desktop computer is getting a brain transplant. Alas, the
nVidia graphics card I've been using won't fit, and the new card is
neither ATI nor nVidia. Now, I know that once it's up and running I can
use either yum or yumex to get rid of all the nVidia cruft, but that's
not what I need to know.
What I want to find out is what, if anything, I'll need to do to get it
booting properly in the first place, as the kernel lines in
/boot/grub2/grub.cfg all refer to kmod-nvidia. (At least, I think they
do, but I can't exactly check right now.) Is there anything special
I'll need to do, either at boot or later to tidy this up?
Last night, I asked this question on the fedoraforum because I know that
there are people there who know about this. Alas, all I'm getting is
responses telling me how to switch from kmod-nvidia to nouveau, which
doesn't help me at all.

Frequent Gnome lock-ups since fresh F18 install
by Digimer
Hi all,
I had F17 and updated it last week to F18. It was perfectly stable
and I had no problems with Gnome.
I did a fresh install of F18 (fresh drive) on Sunday and since then
Gnome 3 has locked up hard on me six times (three times just today).
Each time, I can ctrl+alt+f2 into a terminal and I've tried restarting
various things without successfully recovering.
If I run 'init 3' -> 'init 5', Gnome restarts and the system is
usable again. It seems to happen randomly, though it generally happens
when I am flipping between windows with alt+tab or alt+tilde. That said,
it just crashed on me when I tried to unlock the screen after being gone
for about an hour.
This time, I checked syslog and these were the last messages before
the lock up;
===========
Feb 12 21:38:50 lemass systemd[1]: Starting Getty on tty2...

Feb 12 21:39:22 lemass dbus-daemon[749]: ** Message: No devices in use, exit
===========
This time I tried restarting dbus.service and it closed and,
eventually, restarted Gnome.
This is getting to the point where I can't really be productive with
my laptop. Whenever it hangs, I lose anything not yet saved as gnome
becomes totally unresponsive. I am not sure what I would open a ticket
on even.
Any help would be appreciated.

Failure to draw popup windows or applications after minimization
by Temlakos
Why is it, that after two hours of operation, suddenly popup windows
appear all black? Even Kickstart does this, which means I have a tough
time even shutting it down. And if I have minimized an application and
want to come back to it, forget it. Total, unrelieved black. The
functions are still there, but if I can't see what I'm doing, I can't
use the mouse.
Even the latest updates did not clear this problem.
Where might the fault lie?

Samsung laser drivers for Linux - thinking aloud
by Fernando Cassia
I have an old system around with F16, which I didnt bother to update
to F17 or F18 because I seldom use it (old specs, ancient cpu, low ram
,120GB IDE HD, etc) but XFCE boots and can be used when everything
else fails.
I decided to plug a Samsung 2165W laser to it through its usb port.
The 2165W like many other cheap Samsung lasers are closer to
´winprinters´ because, althought not GDI printers, those use the
proprietary Samsung SPL page description language, implemented in
Samsung´s windows drivers, -but also as Linux binaries, more on that
later-. In other words, these printers don´t enjoy the flexibility of
PCL/PCL5 or PostScript printers that are almost ´universal´ and work
out of the box with little fiddling around.
F16 XFCE showed a nice ´detecting new printer´ dialog on the top-right
side of the screen only to conclude 30 seconds later with ´drivers not
found´ or a message like that, with a ´search for drivers´ button
below.
1. I pressed ´search for drivers´ and the dialog went away, networking
leds flickered a bit, then nothing. (??)
I decided I had to try again, unplugged and replugged the device,
althought this time, after the flickering stopped, it said once again,
that no drivers were found, so I choose the option to ´manually point
towards driver´ or words to that effect. A file selection dialog asks
you to point to a .psd file.
2. Luckily, I had downloaded the Samsung drivers and unpacked those to
the hard drive by then, so I pointed it towards
./drivercd/linux/noarch/bin/(something else, I didn´t keep notes) and
there was a long list of .psd files, one for each samsung printer
model #. I selected 2160 because I know 2160 and 2165 are the same
model# family. Cups did its magic and lo and behold I had a printer
object with the right cups driver.
3. When I tried to print, obviously, it failed (you saw that coming),
the problem ´rasterizer not found´ or words to that effect. It was
complaining about a missing package dubbed ´raster2samsungspl´ engine.
Obviously Samsung´s idea is for one to run the ´install script´ as
root. Apparently it copies binary files around (and libs, like
libstdc++) to fixed destination paths and hopes for the best.
My idea, on the other hand, was that cups should be (by now)
intelligent enought to search for some sort of ´driver description
file´ and install the driver from the cups side, not from a
manufacturer-provided ugly bash script.
I was wrong. apparently the only way to make it work is by running
Samsung´s install bash script.
So the $1M question is: can´t Samsung design drivers which can be
installed via a package manager (rpm), or via a cups install routine,
instead of the current method?. I´m sure they can, in theory.
Which is the right venue to complain about this? (other than Samsung,
which I´m sure couldn´t care less about us Linux users).
There was an ´openprinting´ effort... or perhaps the FSF? or the cups project?.
One would think that by 2013 distros would have gotten around to
design a foolproof way for hardware manufacturers to properly package
drivers (even proprietary blobs) which would then be installed
semi-automagically by the Linux printing subsystem, no?.
Anything wrong with my analysis?. Yeah, I know "just run the darn
manufacturer-provided bash install script and be grateful it at least
works". Yes, that´d be the easy way. I don´t think it´s the right way
going forward....
No, I´m not asking for directions on how to get my printer working.
No, please don´t tell me to update to F17 or F18. No, please don´t
start a flamewar. My point is about the packaging of Samsung´s drivers
and the install method they have chosen. "doesn´t it suck? what -if
anything- can we do to get it improved?".

Fedora 18 with ATI Mach64?
by Michael D. Setzer II
Trying to install Fedora 18 on an older motherboard that has video
built-in using an ATI Mach64.
Install seemed to go thru fine, and login screen is fine, but then
after logging in I got the top bar and side ICONs seem to work
fine, but if background image seems to be half width, and
magenta. Can bring up system settings, and then display, but
have to use keys since the mouse position isn't matching. Screen
is showing as LAPTOP, and it originally shows a 2000+ x 1024
screen, but then options only showed 1024x768 and 800x400.
Selecting either and applying gives the box if image is ok, but it is
diagonal?
Found that the xorg driver for mach64 was not installed, so
installed it. No difference.
Ran Xorg -configure, which I had tried earlier, but it only came up
with a 640x480 screen. This time, the little round icon comes up in
the lower right corner a few times, and then machine completely
locks and requires a hard power off.
Motherboard doesn't have agp slots, so putting a different video
card isn't really an option. Have tried using vnc to connect, but it is
just coming up with an OPPS screen.
Thanks.

how add other language support?
by Franta Hanzlík
As malformed f18 installer not allow select several languages support,
how to add these after installation?
I was expecting do usuall 'yum install @greek-support' (which work
in all F17- releases), but it install nothing, yum end with:
"Warning: Group greek-support does not have any packages to install.
No packages in any requested group available to install or update"
And attempt to install support for German language ends worse:
"Warning: Group german-support does not exist.
No packages in any requested group available to install or update"
And relevant f18 repodata xml files seems define not almost 150
supported languages, but only ~ 40 rather exotic languages
(assamese, bengali, bhutanese, bodo, burmese, dogri, ...).
E.g. greek support is there, but its xml section defines only
several fonts, all escaped with tags <default>false</default> and
<uservisible>false</uservisible> (how someone can install these by
specifying group?)
How now in f18 can be support for other languages installed?
(with yum or on command line)
