NVRAM changes not persistent with efibootmgr
by Gareth Williams
After a frozen install while trying to make a dual-boot system I had
to hard-reboot my laptop using the power button.
On restarting, I was greeted with a UEFI message telling me that there
was no bootable device installed! I quickly inserted a boot CD and
managed to boot into my installed Fedora 20 by editing the
booted CD's grub commands (thank goodness for grub's command line
completion!).
I therfore know that my Fedora installation (including the EFI
partition) is intact and that my crash had somehow corrupted my UEFI
NVRAM.
A quick check with 'efibootmgr -v' confirmed this, as it just listed
the basic 'fallback' paths (no filepaths to the Fedora installed EFI
files).
The simple answer was therefore to re-add the entry for Fedora and
reboot. In order to get the correct syntax for efibootmgr I grep'd
'/var/log/anaconda.program.log' and found:
'efibootmgr -c -w -L Fedora -d /dev/sda -p 1 -l
\EFI\fedora\shim.efi'.
I simply escaped the back-slashes by changing them to
double-back-slashes and ran the command as root.
I confirmed that everything had worked using 'efibootmgr -v' again and
it showed that the entry was there, so I rebooted.
Unfortunately, I was greeted by the same 'no bootable device' message
as before at which point I had to use the boot CD to get back in
again.
To my suprise 'efibootmgr -v' didn't show the entry that I'd just
created - it had simply vanished.
I Googled and Googled and got nowhere. To get out of this
predicament, I installed Fedora again in the partition I'd earmarked
for the dual boot, at which point anaconda os-probed all
partitions/installations, re-created grub's grub.cfg file and fixed
the NVRAM. I was then able to successfully boot my laptop.
Fortunately, there was a kernel update waiting for me, so installing
that reconfigured grub2 and my main Fedora installation was the
default in grub again.
While I'm now working again, there is still the issue of not being
able to alter NVRAM using 'efibootmgr' directly.
My question therefore is: Does anaconda do something else after
running 'efibootmgr' to make it permanent? Or: Why can anaconda update
NVRAM using efibootmgr, while I can't?
Thanks in advance.

Camera mounting
by jarmo
Just found weirdo action. i connect my olympus camera into computer.
Nothing happens, but I can find "unknown" in filemanager. Now try to
open it, I get response, that need to be root, to mount camera into
system???? What? Earlier I could mount it as a normal user...
What has happened, not using selinux or so.. Have updated system some
three times, after last camera mount, so why now have to be root, mount
camera?

F21 Cant login
by Mike Chambers
Just installed F21 via NFS, using KDE as my workstation. It booted up to
the login screen, but it won't login. Have tried both GUI and terminal and
neither will login, whether regular user or root.

Cinnamon / tint2
by Pal, Laszlo
Hi,
In one of the previous update some clever guy made tint2 as dependency
of Cinnamon... I don't know why, but it seems making my favourite
environment much more unstable than earlier. At least handling the
systray is a complete mess... how can I get rid of this tiny but
annoying component?
Thanks

the newest dracut should go into 'emergency' mode and then you can save
the dmesg output onto an USB key.
Unfortunately I've done it before :D

Re: how to accurately test internet upload & download speed
by J.Witvliet＠mindef.nl
(Sorry for TP)
Measuring speed can be a pig.
On the net there are a bunch of sites, claiming they can do this.
However, some require that you have to install all sorts of crap-ware, you to enable eye-candy.
Furthermore, what do you need to know?
Latency or bandwidth, up-stream or down-stream?
And often you and-up measuring the weakest link in the chain, and that does not have to be your connection to your ISP.
One (!) Good way is trying to down load a reasonable large enough file from a site you know that has enough bandwidth, and fast enough storage.
Here in europe, i use ftp5.gwdg.de, a site connected to the university network with 10Gbps
If the file you choose is to small, the measurement in inaccurate: it should take at least about a minute.
Btw, it might be handy to check routing and DNS :-)

Re: Question for Fedora users of Garmin nuvi GPS (SOLVED)

Hello, Everyone
In the USB settings for my Windows 7 virtual machine, this item was
unchecked: "Enable USB 2.0 (EHCI) Controller" The other USB box was
checked, though. So, when I checked the box and clicked "OK",
GarminExpress finally recognized my GPS, and it is now fully updated!
As soon as I applied that setting, I also got a "Found new hardware"
wizard from Windows! Now this kind of thing won't happen to me again.

running instance on OpenStack Folsom release
by Denis Betivu
Hello,
I installed OpenStack Folsom on Fedora 18 according to the instructions I found on this website:

but I encountered an error when trying to launch an instance. I googled a lot but I could not find anybody else
who encountered this particular issue.
