Strange booting problem
by JD
Laptop: Dell Latitude E6510.
OS: F20 with all updates
Grub installed on sda.
Power up ,and after bios's internal works, I do not get the grub menu.
All I get is an empty screen with the underscore cursor blinking at
upper left corner.
Reboot.
Press F12 to get the BIOS boot menu.
Select Internal HDD
Boots just fine.

F22 unusable - system freezes on login
by Matthew Woehlke
(First try apparently got eaten; apologies if this is a duplicate.)
I just installed F22 (KDE spin) from scratch on a new Dell M6800. The
Live CD seemed to run okay, but when I try to boot the installed OS, it
(almost¹) invariably freezes when I try to log in. The machine is
effectively unusable as a result.
Has anyone else encountered this? Can anyone recommend a course of
diagnostics? I'm unable to even get the machine into a state that would
allow remote login (over ssh anyway, and I don't know offhand how to set
up serial login), and I've not seen anything in /var/log/messages that
might indicate a problem.
(¹ *Once and only once* I was able to log in, but the system froze as
soon as I tried to run an application. Also, I can log in in single-user
mode, but this isn't good for much but running dnf and fiddling with
enabled services. I *have* applied all updates as of a few hours ago to
no effect.)

Awk and sort (of text files)
by JD
Hi,
I have text files made of paragraphs of text, separated by
blank lines.
Each "paragraph" is information about a different item.
In need to sort these paragraphs based on the first line
of each paragraph.
Need some hints how to accomplish this.
Thanx.

need grub experts

Bonjour,
I cannot get a correct resolution for grub. Here is my /etc/defaul/grub:
<--------------------
GRUB_TIMEOUT="10"
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT="0"
#GRUB_SAVEDEFAULT="true"
GRUB_DISABLE_SUBMENU="true"
GRUB_TERMINAL_OUTPUT="gfxterm"
GRUB_CMDLINE_LINUX="rd.md.uuid=81f15cb5:748fb5c1:42bef1a6:1ea1ce47
rd.lvm.lv=fedora/usr rd.md.uuid=4a28174a:f38b4938:233f85f7:6ce585a8
rd.lvm.lv=fedora/racine rd.md.uuid=9f878179:a58f5c78:f645e22e:d7d3c896
rd.lvm.lv=systeme/swap rhgb quiet"
GRUB_DISABLE_RECOVERY="true"
GRUB_GFXMODE="1280x1024x32"
GRUB_GFXPAYLOAD_LINUX="keep"
GRUB_BACKGROUND="/boot/grub2/themes/system/fireworks.png"
#GRUB_THEME="/boot/grub2/themes/system/theme.txt"
export GRUB_COLOR_NORMAL="light-gray/black"
export GRUB_COLOR_HIGHLIGHT="magenta/black"
GRUB_FONT="/boot/grub2/unicode.pf2"
<-------------------------
So, as far as I read the grub doc, because of
GRUB_GFXPAYLOAD_LINUX="keep"
It is suppose to apply the 1280x1024 resolution to the console during
the boot. But it is not the case! I get this resolution only with the
grub first screen: fireworks image and the entry list.
What is missing in my config?
Strangely, I have a "custom file": /etc/grub.d/40_custom, to boot a
debian install:
<-------------------------------
menuentry 'Debian GNU/Linux, avec Linux 3.2.0-4-amd64' --class
debian --class gnu-linux --class gnu --class os {
load_video
set gfxpayload=keep
insmod gzio
insmod mdraid09
insmod part_msdos
insmod part_msdos
insmod ext2
set root='(mduuid/eb8b5efe5a8f9369e940a0f383d63ad1)'
search --no-floppy --fs-uuid --set=root
17e0b155-4d77-4769-b568-723329c5f656
echo 'Chargement de Linux 3.2.0-4-amd64 ...'
linux /vmlinuz-3.2.0-4-amd64
root=/dev/mapper/debian-deb--racine ro quiet
echo 'Chargement du disque mémoire initial ...'
initrd /initrd.img-3.2.0-4-amd64
}
<-----------------------------------------
In that case, the "set gfxpayload=keep" instruction succeeds to give
the correct resolution during the debian boot.
Thanks for any help and suggestion.

Thunderbird blinking browser notice -
by Bob Goodwin
This is Fedora 22, 64 bit, XFCE, etc. with Thunderbird 38.0.1
When I click on a URL in an e-mail message it immediately starts a
blinking browser notice at the top left. I know, I've just selected a
URL and don't need that annoying/distracting box. It's as though I am
being implored to go look at it immediately but I would like to continue
reading messages before doing so.
Does anyone know how to eliminate it or at the least stop the stupid
blinking? Google hasn't helped me ...

"software": how does it really work?
by Andrea
Hi,
I'm on Fedora 22 default gnome desktop.
I've got a few questions about "software"
1) how does it integrate with dnf? for instance if I do "dnf history" I do not see any of the
transactions done with the "software" app.
2) do "software" and dnf have the same source? there are packages available only via dnf.
3) when I check for updates "software" most of the times says
"up to date - nothing to do - checked at XX:YY" (maybe 2 minutes ago)
Then I force it to check and often it finds something to update. Once it is a coincidence, but is it
possible that so often updates are published just in the few minutes between the automatic and
manual check?

How do you define safely? It means the entire MBR record is invalid,
including the partition scheme.
# wipefs -a /dev/sdb
Will do exactly the above on MBR disks, it removes the MBR signature
making it invalid. If the GPT partition scheme is used, wipefs will
remove the GPT primary and backup header signatures, and the PMBR
signature, making all three of them invalid and thus not a partitioned
drive.

After installing Fedora Workstation ...
by JD
During install, Anaconda let's you select one desktop from
the left column, and then select the groups of packages from
the right column.
Fine.
Now that fedora is up and running, how does one add a group
of packages ala the groupings presented by anaconda?
Where is the list of such group names documented, what
packages they contain, and how to install them.
Thanx!!!

Toshiba support in the kernel.
by Lain Cortés González
So, as I'm not a hardcore developer or coder, I was wondering: Is the
new support that it's dropped in the kernel for the Toshiba laptops
build by default or I'd have to compile by myself from "scratch"?
