regressions between kernel 2.6.32 and 2.6.33
by Chris Rouch
I've recently noticed problems with the kde power management with f13
and as part of debugging this i've come to the conclusion there are
serious (for me) regressions between kernel 2.6.32 and kernel 2.6.33.
I have a fully up to date f13 laptop. If I boot the original f13
kernel (kernel-2.6.33.3-85.fc13.x86_64) I see the following problems:
nouveau driver hangs randomly - very often if i have 3d effects
enabled. it needs a soft or hard power off to fix.
if i use rpmfusion nvidia drivers, normal use is fine, but the system
hangs on exit and needs a soft or hard power off to fix.
After a hard power off the system hangs at "starting udev" on the next
boot, and needs ctrl-alt-del to fix.
with either driver the screen does not lock when the lid is closed
with either driver kde power management does not work
However if I install a recent F12 kernel
(kernel-2.6.32.16-141.fc12.x86_64) then I see
nvidia drivers work as expecte and exit and restart normally
screen is locked when the lid is closed
power management works as expected.
(nouveau is not present in this kernel, I believe)
Obviously running such an old kernel is not a long term solution.
I've already raised a bug about the nouveau hangs, and I intend to
file one regarding these regressions, but before I do so I'd like to
ask if anyone else has seen them or thinks that there may be a
solution I can implement myself.
And in case you're wondering - I will be very happy to move
permanently to the nouveau drivers just as soon as they're stable
enough. I think that day is probably not soon though.

Chris

On my system, it was only in this place, but was already set.

This was already set too.

Bingo! For whatever reason, upowerd is not running. If I start it by
hand everything works as expected. So now I need to find out why it's
either not being started or is failing silently. According to the man
page it should be started by dbus-daemon, which is running, "whenever
an application calls into the org.freedesktop.UPower service"
Thanks for your help so far.

Menu Editor
by Timothy Murphy
I've added an entry with Menu Editor (right click on f-button in panel)
to enable ssh -Y <remote host>.
I've set "Run in terminal" on the Advanced tab.
This works, except that I get a white-on-black screen
with nothing at the top of the screen to change this.
On another laptop, with exactly the Menu Editor setting
I get a nice page with the usual File-Edit-View tabs at the top.
I'm wondering what actually sets the look of the screen?
Is it a default konsole setting, or is it something to do with ssh?
Or perhaps a shell setting?
I see that there is Menu Editor setting with "Run in terminal"
to set Terminal options, but nothing I have tried there
has has any effect.
I should say that I am running Fedora-13/KDE on this laptop.
Any and all advice gratefully received.

camera won't automount
by Claude Jones
I'm having problem with one device, a Nikon D90 camera, that won't
automount. At some point in the past, I had set something that would
cause it to be detected, but the only option offered was to download
pictures with Digikam. (At some time in the past, the device notifier
would offer options including opening the device in Dolphin which is
what I'd prefer.) For some reason, this function didn't work properly
because Digikam would open and stall on the process of detecting my
images, and never would open. I have a very large image archive and this
process could take a couple of minutes in the past, but it would
eventually open. This camera will mount under Windows; however, in
Windows, the icon never appears that allows you to eject it gracefully
once you're ready to dismount it. When I attach the camera to the
Windows box, it automatically opens an explorer window and shows me the
folder structure, but, the eject button never appears.
What I've done:
I've gone into the device notifier widget settings and tried finding
there, a way to disable the mount with Digikam option, but could find
nothing there that affected the behavior
I've removed the device notifier widget and re-installed it - no difference
I found the auto-mount files "device-automounter-kcmrc" and
"kded-device-automounterrc" and renamed them and restarted KDE - no
difference
I removed Digikam (I really don't want to use this app anyway, as I find
it cumbersome) - now, the device notifier doesn't ever show the camera
I re-formatted the memory card in the camera
Lots of google searches on this issue, but haven't found anything else
that helped
Tried my other camera, a Fuji 9000, and several pen drives - these all
automount successfully and offer various options for how to mount the
devices with various applications
The strange behavior under Windows (it automatically opens a folder with
the camera memory card's root folder displayed, BUT, never produces the
eject icon) makes me suspect this is some issue with the camera, but,
what could it be?

Red Hat employees listed in manpage have blocked addresses? Unreal.
by Gene Heskett
Greetings list;
2 redhat employees are list as the authors of logrotate in the manpage, so
I just sent them a question because it isn't working as expected.
Both emails bounced in the time it takes my fetchmail script to go suck the
next cycle. Effectively instantly and permanently.
So how does one go about asking for logrotate help for a non-redhat
distribution?
I am not running fedora atm.
Thanks.

Problem with an external usb HD - slow usb
by Luigi Castro Cardeles
Hi list,
I use fedora 12 on a dell inspiron 1545 laptop.
(2.6.31.12-174.2.22.fc12.x86_64).
i have a external usb hd and i can't make it connect like a usb 2.0 device.
this device is ntfs format
I check if the device is using ehci (dmesg after i plug the device)
[root@localhost ~]# dmesg | grep USB
usb 2-2: new high speed USB device using ehci_hcd and address 2
I check if this device is connected on a usb 2.0
[root@localhost ~]# lsusb
Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 015: ID 0471:2021 Philips
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
I mount the device with this options:
/dev/sdc1 on /media/hd_backup type fuseblk
(rw,nosuid,nodev,allow_other,blksize=4096)
but when i use cp, mv or rsync, the max speed i get is max 6MB/s (a lot
800kB/s).
If i use this device on Windows (tested with Vista and Seven), i get much
high transfer rate.
I read about sync and async options, but if i put sync or async on fstab, it
does not alter the transfer rate.
Is this the normal upload transfer rate? I am doing something wrong?

ipv6 udp and ip6tables headache
by Michael Cronenworth
Server:
nc -l -u 64739
<type letters, client doesn't see them>
Client:
nc -u intranet 64739
<type letters, press ENTER>
nc: Write error: Connection refused
Server:
nc -l 64739
abc
Client:
nc intranet 64739
abc
(both ways works through TCP)
My ip6tables config is allowing all traffic through eth1 (-A INPUT -i
eth1 -j ACCEPT). eth1 being the network card that is on the server that
is physically connected to the same network as the client. All IPv6 TCP
traffic is working great. SSH, HTTP, etc.
What am I missing?
Thanks,
Michael

Test upgrade from F13 to F14 using LVM snapshot?
by Richard Shaw
I was thinking of trying a DVD based upgrade (or pre-upgrade) from F13
to F14 Alpha (or later Beta, etc) using LVM snapshots so if things go
poorly I theoretically would just have to drop the snapshots and
things would go back to F13. The exception would be the /boot
partition, but it should be possible to keep my old kernels, yes?
Has anyone tried this?
Thanks,
Richard
