Java symbolic links broken on Fedora 19?
by Dave Johansen
I have a system that I upgraded from Fedora 18 to 19 recently and I
just installed eclipse, but it says that there's no JVM when I try and
run it. I noticed that /usr/bin/java is a symbolic link to
/etc/alternatives/java which is then a symbolic link to
/usr/lib/jvm/jre-1.7.0-openjdk/bin/java but it's actually installed at
/usr/lib/jvm/jre-1.7.0-openjdk.i386/bin/java.
Is this an issue from the update from Fedora 18 to 19? Or is it an
issue with the packages in Fedora 19?
Thanks,
Dave

Problems with USB-connected printer
by Geoffrey Leach
Here is dmesg}tail from an unplug-plug of the USB cable
[20091.736439] usb 2-1.1: USB disconnect, device number 21
[20096.780904] usb 2-1.1: new full-speed USB device number 22 using ehci-pci

[20098.217202] usblp0: removed
You'll note that the USB device is a "controller" not the actual printer. The "controller" is a USB-parallel adapter to the printer, an HP LaserJet 1300.
Some data.
Printing is sporadic. Mostly the job just hangs, but sometimes it actually prints.
"Self test" (from Administration=>Print Settings) works, but "test Page" does not.
"cat foo | lpr" hangs.
All of this is from Fedora 19. Under Fedora 17 printing often worked, but always worked if I plug-unplug the USB cable.
I'm puzzled by the last "usblp0: removed". It seems that this is consistent with the behavior, but I have no idea what it would happen.
Suggestions as how to proceed would be appreciated.

USB button
by Fernando Cassia
Is there a dirt-cheap usb GPIO that I can plug in a USB port on Linux
and with minimal C code (or even bash) detect such button press and
trigger some action?
Im looking for a single digital input... I know there are some hacks
like disassembling a dirtcheap usb keyboard, but I wonder if theres
some device for embedded use that people on this list might have some
experience with...
TIA for any ideas

Partition fuckup
by Martin S
Hi,
Now I'm pretty pissed with myself as i managed to fuckup the partitions on my
laptop.
I've got 2 partitions one with 50 Gb the other with 250 Gb.
Unfortunately they contain the wrong things.
/ is 50 Gb
/home is 250 Gb
I want them the other way round really.
What would be the best way of trying to achieve this?

UEFI boot hangs (almost) all the time
by mikeromberg@comcast.net
I'm attempting to install Fedora 19 on a Dell inspiron 15z which
came with windows 8. I would like to be able to dual boot the laptop
between the two. It is not going real smoothly.
Things I am assuming:
- Windows 8 is installed to boot in UEFI mode. Changing this
probably involves more pain and suffering than would be considered
decent in any modern civilization. So, Linux must boot in UEFI
mode as well.
Things I know:
- The live-CD boots fine in "legacy" mode.
- Windows 8 does not care if "secure boot" is enabled. So, I
disabled it.
- The live-CD almost never boots in UEFI mode. It hangs after
displaying either "Secure boot disabled" or "verified by vendor
certificate". From what I read this means the shim ran. But
nothing at all happens past this point.
- The live-CD did boot exactly one time! I then used it to install
fedora to the hard drive. It has never booted again.
- Grub appears to be installed on the EFI partition and does display
a menu when the laptop boots.
- Grub *CAN* boot windows 8 in UEFI mode.
- The fedora installation on the hard disk hangs after the same
message as the live-CD
- I can mount the fedora install with the netinst-CD image (booted
in legacy mode). And used it to run yum update to upgrade grub
and the kernel. But... Still the same hang at boot for fedora.
It seems to me that something is going wrong when grub tries to hand
things over to the kernel. Does anyone have any suggestions about how
I might make grub and the kernel a bit more chatty about what is going
on? Or does anyone have anything else I might try? I could wipe the
disk and switch to legacy BIOS boot. But I really don't wanna go this
route.
Thanks,
Mike

Moderately step in when there are persistent complaints. You have managed
to generate more complaints despite your own self judgement of how often
you have engaged in poor behavior. Trying to play the victim doesn't help
with that.

Simultaneous graphic and non graphic display at boot
by Jonathan Ryshpan
A couple of odd changes in the boot display recently. I run the
non-graphics version; that is /etc/default/grub contains the line
GRUB_CMDLINE_LINUX="rd.md=0 rd.lvm=0 rd.dm=0 SYSFONT=True KEYTABLE=us rd.luks=0 LANG=en_US.UTF-8"
Note that the line does not contain "rhgb quiet".
The issues are
* A few months ago, the font in the display changed from a small
font to the standard console display font, the same one used by
the BIOS, also the penguins at the top of the screen
disappeared.
* Recently, starting yesterday, the messages are displayed
simultaneously with a version of the graphic startup message;
this one is a bar at the bottom of the screen showing white and
two shades blue that move across the screen from right to left
summarizing boot progress. The attempt to show both makes a
mess of the screen. The double display starts immediately after
the message "Welcome to Fedora 19 (Schrödinger’s Cat)!" appears.
* The halt process (equivalent to "$ shutdown --poweroff", but
usually started from the KDE panel) frequently pauses for long
periods of time or freezes completely. I can usually, though
not always, get it unfrozen by pressing the start button on the
computer.
I'm not sure what connection, if any, there is between all these, but it
looks suspicious.
