HDMI-connected flat panel keeps blanking
by Robert P. J. Day
i just HDMI-connected a gateway flat panel display to my f12 laptop,
and configured the display to span. in short order, i got the
standard f12 desktop background to display on the flat panel and, yes,
i can move the cursor off the right-hand side of my laptop and watch
it magically appear on the left-hand side of the flat panel.
the problem is, the flat panel keeps blanking -- literally every
several seconds -- and then comes back. does this output from xrandr
look reasonable?
# xrandr
Screen 0: minimum 320 x 200, current 2560 x 800, maximum 8192 x 8192
VGA-0 disconnected (normal left inverted right x axis y axis)
LVDS connected 1280x800+0+0 (normal left inverted right x axis y axis)
0mm x 0mm
1280x800 60.0*+
1280x720 59.9
1152x768 59.8
1024x768 60.0 59.9
800x600 60.3 59.9 56.2
848x480 59.7
720x480 59.7
640x480 59.9 59.4
HDMI-0 connected 1280x800+1280+0 (normal left inverted right x axis y
axis) 442mm x 249mm
1600x900 59.9 +
1280x800 59.8*
1152x864 75.0
1280x720 60.0
1024x768 75.1 70.1 60.0
832x624 74.6
800x600 72.2 75.0 60.3 56.2
640x480 72.8 75.0 66.7 60.0
720x400 70.1
the setup seems correct, except for the persistent blanking.
thoughts?

Bug in /etc/cron.d/mlocate.cron or am I crazy?
by Steven W. Orr
I can't believe this is a real bug. I'm submit it to bugzilla. It's in F10, 11
and 12. I'd be curious to know just how old this bug is.
Contents of mlocate.cron is:
#!/bin/sh
nodevs=$(< /proc/filesystems awk '$1 == "nodev" { print $2 }')
renice +19 -p $$ >/dev/null 2>&1
ionice -c2 -n7 -p $$ >/dev/null 2>&1
/usr/bin/updatedb -f "$nodevs"
Unless I'm going cuckoo, I'm guessing that the intent was for line two to be:
nodevs=$(< /proc/filesystems | awk '$1 == "nodev" { print $2 }')
and if we're going to go that route, why not go the full banana
nodevs=$(awk '$1 == "nodev" { print $2 }' < /proc/filesystems)
In fact, this is still sort of screwed up. How about:
#!/bin/bash
get_nodevs()
{
local line
# Return ret as a global
while read line # Read each line from /proc/filesystems
do
if [[ "$line" =~ $'^nodev\t(.*)$' ]] # Do a real regex
then
(( ${#BASH_REMATCH[@]} == 2 )) && ret="$ret ${BASH_REMATCH[1]}"
fi
done < /proc/filesystems
ret=${ret:1} # Lop off the leading space.
}
ret=''
get_nodevs
nodevs="$ret"
{
renice +19 -p $$
ionice -c2 -n7 -p $$
} > /dev/null 2>&1
/usr/bin/updatedb -f "$nodevs"
Note that as it was written, it did not properly take into account the empty
first token.
If I'm right that this is a bug, then I don't expect the Nobel Prize, but
surely, a T-shirt should accompany a discovery of a bug of this magnitude. How
long has this bug been in existence?
Also, I don't know about the rest of you guys, but this script used to hang on
me on a regular basis. I'll look and see awk just hung. This bypasses awk or
any pipe at all and will never hang.

What'd I do wrong?
by John Aldrich
I installed a new SATA drive in my linux box that had previously (except
for my dvd-rw) been all PATA. I then tried to install F12 on it, and told
it to put GRUB on the new drive.
After I finished installing, I rebooted and it tried to boot F11 again. I
rebooted, went into BIOS and changed the order of the drives to put the
SATA drive in as the primary drive, and let it boot. It just hung. So
obviously something isn't right.
I went back into BIOS and changed the order of the drives back and now I'm
back in F11. How do I get this fixed, w/o disconnecting the PATA drives? Do
I need to change the order of the drives in BIOS and reinstall???
I've never tried to put a fresh drive in and boot off it, so I could use a
bit of help here. :-)
Thanks!

expect command spawns incorrectly
by Donald Russell
I am trying to use the expect program to automate an sftp process....
The expect file begins with
spawn sftp -oProxyCommand='....' user@host
expect "password:"
send "sesame\n"
expect "sftp> "
It never gets the part to ask for the password, instead the sftp command
fails, showing the "usage".
However, if I cut/past the sftp command, it work fine...
It's as though the expect program is somehow messing up the command string
to be "spawned".
I've tried various uses of quotes and so on, but I just can't get past this.
The -d option on expect doesn't really show me the correct detail other than
it says it is spawning the correct commend... yet sftp always returns with
"the correct usage help text", so obviously what it says it's doing and
what's actually being done isn't quite the same.
Does anybody have any experience with "expect" that could shed some light on
this?
Thanks

F12 EEEPC 1000H WLAN with hidden SSID no go
by Bernd Bartmann
Hi,
I just installed F12 on my EEEPC 1000H. Everything is working fine
besides the WLAN connection to an access point with hidden SSID.
I installed the rt2860 drivers from rpmfusion, activated
wpa_supplicant and now I can see the WLAN acces point of my neighbors
in Network Manager, but after entering the details of my own hidden
WLAN Network Manager keeps asking for the WLAN passphrase again and
again.
I also have Ubuntu 9.10 on this EEEPC and there the connection to my
hidden WLAN worked out of the box. Also, on a DELL D620 laptop with
Intel WLAN card and F12 the connection to my hidden WLAN works just
fine.
Any ideas how to get this going on the EEEPC in F12?
Best regards,
Bernd.

Setting up a VM to run XP in an up-to-date F12 box?
by mike cloaked
Can someone point me to a good step by step howto to set up Windows XP installed
from an iso in a VM in F12 using kvm. There are some XP applications that only
work in XP itself rather than in wine or Crossover.
I have not tinkered with virtualised machines before so this is a learning curve
for me.
I did see the http://docs.fedoraproject.org/ guide on virtualization but there
seems to be quite a number of changes in the details of what is presented on
screen when starting to install a new VM on my screen compared to what is in the
guide. The laptop in which I want to do this does have the virtualisation flags
so in principle it should be possible.
It is not clear where the virtualised machine would get installed by default -
but it looks like it would be in /var/lib/libvirt/images which is on the root
partition in my case so I made a new directory in a bigger partition with plenty
of space, and bind mounted it ahead of trying to create a new VM.
Thanks in advance.

Re: TV tuner, sound etc. -- what does this mean?
by Bill Case
Hi;
I have been going through my messages log and saw this.
...
kernel: tuner 2-0042: chip found @ 0x84 (cx23885[0])
kernel: tda829x 2-0042: could not clearly identify tuner address,
defaulting to 60
kernel: tda18271 2-0060: creating new instance
kernel: TDA18271HD/C1 detected @ 2-0060
kernel: tda829x 2-0042: type set to tda8295+18271
...
Is this normal, or does "could not clearly identify tuner address"
indicate a problem?

Trying to get Audio Working on F11
by Reg Clemens
OK, I seem to have backed myself into a hole in the ground.
I have recently installed F11.
I noticed that sound was not playing on the few videos that would play from
youtube (the rest of the videos are waiting for me to get flash working a
separate problem).
I tried aplay, me and root. Nothing.
I removed pulseaudio with
yum remove pulseaudio
and now aplay could play sounds as root, but not me.
I checked /dev/snd, and it is 660 root and audio.
I changed that to 666 and I could play sounds as me.
OK, back up, changed it back to 660, and added myself to the audio group.
FOR SOME REASON this did now work. Mumph, no sound as me.
OK, decided to back up again.
Reinstalled pulseaudio, but was back to where I was to start with, no audio.
Reremoved pulseaudio.
But NOW I dont get sound with aplay under any conditions, not me, not root.
So, I dont know where to go next.
I currently have no sould from aplay, nomatter who the user.
Things were so much simpler back before this pulseaudio thing came along.
Mumph.
Any thoughts on what I should try next, and please dont suggest
reinstalling F11...

firefox repeatedly crashes while trying to save bookmark
by Paolo Galtieri
I start firefox (64bit) with one tab pointed at start.fedoraproject.com
I try to save a bookmark to this page by bringing up the bookmark this page
dialog from the menubar. I click on the "show all bookmarks folders" arrow
and I get a dialog box showing all my bookmarks and bookmark folders. I
start to scroll down the list and when I get about 3/4ths down the page
firefox crashes. This has occurred every time I have tried it. I'm running
latest FF on 64bit F12. Anyone else experienced this?
