Problems with screen to serial usb on F17
by Robert Moskowitz
I have an old F17 Asus Eee700 and trying to hook it to a USB TTL UART as
a serial console to some armv7 systems using screen:
screen /dev/ttyUSB0 115200
I am getting garbage characters. Not all the time, but particularly at
the beginning. I don't see this on either of my two F20 systems:
Lenovo x120e and Asus Eee900.
I can't easily upgrade this Eee700 and I would be happy just using F17
screen. But is this likely to be OS or hardware?

bootstrapping from a USB stick
by D. Hugh Redelmeier
I have an oldish PC that only understands booting from 512-byte
sectors and then only with MBR disks.
I want to install large new disks on it, and no old disks. These
don't even pretend to do 512-byte sectors: 4k all the way (3T and 4T sizes
aren't good for MBR either).
I was thinking that I should be able to use a USB flash memory stick
as the boot device, loading GRUB from there, and then having it boot
the OS from a big GPT hard disk. The stick would be permanently
plugged in.
Is there any reason that this might not work? Is there a better way?
Are there special GRUB modules that I need to convince GRUB's
installer to put on the USB stick?
What filesystem type is best for the USB stick? My guess: ext4 is
fine.

Cannot unlock screen after prolonged period of time
by Where Where
Greetings everybody!
I'm a new convert to Fedora. I finally got it installed (hurray!) but ran
into this issue:
If I lock the screen using mod-L and immediately enter my password to
unlock, the screen unlocks.
But if I leave my computer be for an hour and unlock, Fedora doesn't accept
my password.
Some peculiarities of my setup:
* I am using full disk encrypting using an LVM volume. Fedora setup set up
my partitions for me.
* I'm using a recent Macbook.
I have all the latest updates installed for Fedora 20. My architecture is
AMD64, and I'm using the standard (GNOME) spin.
How may I move forward?
Thanks for your attention!

Yes, I have used Puppy in the past - it is worth a shot since I am
getting desperate . .
The other thing (which might just have been coincidence) is that when I
booted on the USB for the LiveCD, it did seem to stay up without any
problems - but the PC was not in that state for long periods of time so
I might just have been lucky at those times . .
Thanks,
Phil.

OT: Recognizing USB audio device
by Jonathan Ryshpan
I have a USB audio device which is recognized correctly on my Fedora
system (Fedora-20 with all updates running KDE) but is not recognized by
another Linux system (a Samsung Chromebook). Can anyone tell me how
Fedora recognizes the device, so I can figure out whether it would be
practical to tweak the Chromebook to get it to recognize the device.
The device shows up this way:
$ lsusb
...
Bus 005 Device 003: ID 08bb:2702 Texas Instruments Speakers
...
and appears in my alsa configuration as:
$ aplay -l
...
card 1: PCM2702 [Burr-Brown Japan PCM2702], device 0: USB Audio
[USB Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0
...
Any info/hints/links/etc would be much appreciated.

Unexpected upgrade
by Aaron Konstam
I have been away from Fedora for awhile so forgive me if the answer to
my question is well known.
I installed FC18 onto my laptop when it forst cam out some time ago.
Since then all I did was yum upgrades and selected yum installs. So I
was surprised to find that the version running on my laptop was FC20.
How did this happen?

Secure Transactions
by Tod Merley
Hi all!
I have been using Windows monitored by Norton used almost exclusively to do
on line transactions and banking. The strategy is simply that I do not use
it otherwise. Transactions only.
But then the W8 laptop Norton would not update or scan!! First attempts at
fix failed and refresh and reload – well – simply have not worked out so
far (long long story). Then the crazy windows update problems this month
have made me a bit shy to use the W7 installs I have.
So I made up some Fedora 20 flash drives to more or less imitate the basic
“used exclusively for transactions” function I was using Windows/Norton
for. So far so good! Indeed I find banking using FireFox on Fedora simply
easier to use (better fonts, colors, I think).
I am simply seeking thoughts on the basic approach, alternatives, other
things to do to make a secure transaction environment.
Thanks all!!

su - Authentication failure - reinstall fedora ?
by Angelo Moreschini
Hi,
after that I installed fedora 20, I am not able to get the login as su.
When I try to sign me as super user, I always get the answer
"Authentication failure".
I don't think that I really type wrong the password that I set at install
time:* I typed it twice*.
Rather I think that they are some funny characters inside it.
So I lost the hope to try to guess the password and I think to re install
Fedora.., but I have a problem.
My computer is dual boot with Windows XP and I am not sure how uninstall
Grub (how to manage the MBR when to the computer start) before to uninstall
Fedora...
Some time ago I tried to fix this problem using Windows in recovery mode
(command fixboot) and, at last, I had to reinstall also Windows XP (further
that Fedora)..
Can I have an advice how to arrange the dual boot on my computer, before
to uninstall Fedora??
Thank you
regards
Angelo

I will check them out but all the hardware was bought originally (years
ago) to be compatible . .
Thanks,
Phil.
