Problem with hibernation
by Timothy Murphy
My laptop has ceased hibernating.
When I click on f=>Leave=>Hibernate
the sleep-moon starts flashing
and the small hyphen-like symbol on the top left comes on as usual,
but as far as I can see nothing is written to disk.
At this point it becomes impossible to communicate with the machine.
Ctrl-Alt-F2 does bring on a text window,
with a login: request,
but if I enter my username and press Return
I am not asked for a password.
Whatever I type appears on the screen,
but with no effect.
I tried stopping the NetworkManager and openvpn services
which seemed to me the most likely causes of the problem,
but that had no effect.
I wonder if anyone has had the same problem?
And if so, whether there is a solution?
I'm running the current kernel,
but I tried the last 2 kernels without effect.

printer problems F13
by Gregory Pittman
Last week I was suddenly faced with the loss of all printers in my
settings. This is on a netbook that I carry around and therefore have
5-6 printers set up for use.
What I have noticed since then are the following features figured out
with lots of trial and error, finally some success.
1. Plug-n-play automatic detection and setup of printers no longer
happens. Other USB devices get found as usual.
2. trying to use the menu-based Printer configuration ends with it
finding the printer, then telling packagekit to look for drivers, after
which it says that the drivers are installed, and it quits with an error.
3. Using the menu-based HPLIP, it cannot find any printers connected to
a USB interface, another show-stopper.
4. Using 'hp-setup' on the command line by root will allow for USB-USB
printers to be set up. This will not work for USB-parallel connections,
since this still cannot find any devices connected to the USB interface.
5. Using 'system-config-printer' on the command line by root will allow
for setting up a USB-parallel connections printer.
I've tried going back a couple of kernels to see if that made a
difference, but it didn't.
This is very annoying, and I wondering if anyone has any explanation for it.

Re: Files named in Chinese characters couldn't display properly in Fedora 12
by Ding Yi Chen
Perhaps you can set the putty to use Chinese font,
I used to use putty with Chinese BBS, should be all right.
Or you may want to try pietty:

Unable to set txpower on wifi card

F13, latest updates.
wifi card: Sparklan wmir-200N

I tried to set txpower to 14 per datasheet spec:
$ sudo iwconfig wlan0 txpower 14dBm
Error for wireless request "Set Tx Power" (8B26) :

The drivers that are loaded for this wifi card are:

Is this an issue with the wext driver or with the rt2XXXXX drivers?

Unable to disable wireless with latest NetworkManager-gnome
by Gianluca Cecchi
Hello,
two days ago I updated my FC13 x86_64 from
Jul 28 08:52:35 Updated: 1:NetworkManager-gnome-0.8.1-1.fc13.x86_64
to
Aug 28 16:20:47 Updated: 1:NetworkManager-gnome-0.8.1-4.git20100817.fc13.x86_64
and now I'm noticing I'm not able to disable wireless any more.
My nm-applet process is active
gcecchi 2306 2167 0 07:46 ? 00:00:00 nm-applet --sm-disable
and I see the double-monitor icon, but usually I right-clicked on
nm-applet window and checked out the "enable wireless" option.
Now I see that the first two lines are enabled but greyed out....
Is this expected behaviour from update? I don't see a reference inside
the rpm changelog...
I remember some past threads (probably in FC11 time...) where it was
requested to keep wireless state as last session.
It worked for some time but then nm-applet came back to be always
enabled, so that I have to manually disable each time I didn't need
it... any news on this?
Was this "remembering last state for wireless on next reboot" feature
abandoned, or do I have to open a bug?
BTW: I wanted to make a screenshot but if I right click and then press
the stamp button I do not have the "save screenshot" pop-up... any way
to do it (without a digicamera.. ;-)
Thanks,
Gianluca

Advanced Format drives + RAID5 + LVM + EXT4 = migraine
by Jake Peavy
Hey all,
I'm going a little off my rocker here trying to understand how to best
configure a 3-drive RAID5 array using the new Western Digital 4k sector
drives.
I've got 3xWD15EARS (1.5T 4k sector advanced format drives).
If I was using the drive as-is, my understanding is I should create a
partition starting at sector 64. This would solve all my problems.
But I want to put them into a RAID5 array, so currently I didn't partition
at all and just passed mdadm the whole drive. Not sure if this is the best
approach. I used 512kB as chunk size.
Then I want to create LVM on the array. I didn't pass any special parms to
{pv,vg,lv}create (should I?)
Lastly, I want to create an EXT4 filesystem on the array. I used the stride
calculator at http://busybox.net/~aldot/mkfs_stride.html<http://busybox.net/%7Ealdot/mkfs_stride.html>
with
raid level = 5, devices = 3, chunk size = 512 and filesystem blocks = 4 (?)
which suggested I use mkfs.ext4 -b 4096 -E stride=128,stripe-width=256
(which I did).
After doing all this, I get writes to my filesystem of only 38MB/s. Reads
of 119MB/s.
[root@morbo opt]# hdparm -Tt /dev/mapper/array_vg-lv_opt
/dev/mapper/array_vg-lv_opt:
Timing cached reads: 1574 MB in 2.00 seconds = 786.85 MB/sec
Timing buffered disk reads: 332 MB in 3.00 seconds = 110.57 MB/sec
[root@morbo opt]# time (dd if=/dev/zero of=zerofile bs=1M count=8192; sync)
8192+0 records in
8192+0 records out
8589934592 bytes (8.6 GB) copied, 226.646 s, 37.9 MB/s
real 3m51.062s
user 0m0.072s
sys 0m39.794s
[root@morbo opt]# dd if=zerofile of=/dev/null bs=1M
8192+0 records in
8192+0 records out
8589934592 bytes (8.6 GB) copied, 72.4094 s, 119 MB/s
I have a feeling my array should perform much better than this and it's
probably because I haven't taken the 4k sector size into account and I'm
bleeding performance.
Can anyone comment? If I need to take the 4k sector size into account,
where should I do so? With partitions? In pvcreate? Some other place? Or
multiple places?
TIA,

network mgr applet - cannot disable wireless
by Genes MailLists
Often when I do backups on laptop, I'll plug in wired ethernet - NM
happily switches the connection from wireless to wired -
however it always leaves the wireless on as well
+ correct if its a different subnet than wired
+ arguably wrong if its the same subnet - probably a bug ? - or at
least it should offer to shutoff wireless when the 2 subnets are the same.
Since the route via wireless is active, the backup could/does use
wireless instead of wired. So I usually right click the nm applet and
disable wireless.
Today - that option along with the disable netowrking option are
grayed out and I can not uncheck the 'emable wireless/networking radio
buttons.
This is f13 - fully updated (+ some testing and 2.6.32.6-47 kernel
from koji). NetworkManager is 8.1.4.git20100817.
Anyway know what causes this or suggestions on how to deal with it ?
Thanks ..

F12/13: Ndiswrapper, topdog Wifi, Thunderbird & network degradation...
by Dan Thurman
I have a gateway M-6750 laptop which sports a
Marvell TopDog wifi chip. I have obtained the
latest drivers for this chip, and used ndiswrapper
to hook itself to the XP/Vista topdog driver, and
it at first appears to be working... although there
are crash data appearing in the log files but other
than that, it continues on working.
I can use Firefox, and Pidgin and the network
appears to work fine.
But the minute I start Thunderbird, it appears the
wifi/network performance is severely degradated
as TB is trys to sync the IMAP server data with
local data storage. It knocked out pidgin. gkrellm
displayed Xorg was hitting CPU hard, Nautilus
froze for a time, gnome terminal blocked text entry,
basically, everything appeared eratic. But given
several minutes of time for TB to settle down and
to finish its tasks, the system seemed to return to
some sense of normalcy - just slightly better.
While this was going on, I thought I'd ping a local
server to get some sense of what is going on with
the network since I cannot think of a better diagnostic
test, and the summary is shown below but watching
each ping line, there appeared many times, complete
line display stoppage running several seconds before
the next display appears.
42 packets transmitted, 41 received, 2% packet loss, \
time 41873ms
rtt min/avg/max/mdev = 0.754/359.603/2005.013/581.445 \
ms, pipe 3
Line by line data, the highest delay was 4000ms at that
short time of testing.
Is there anything I can do to see why there is network
degradation and if it is related to ndiswrapper or not?
I tried wired LAN and there is no network degradation?
