[Bug 574105] Re: Ubuntu does not recognize internal wireless adapteron Samsung R780 laptop

theUg — 2010-11-05T05:15:12

After 10.10 update wireless still does not work, however, is being
recognized (network manager says “Wireless network (Realtek RTL8192E)”
instead of plain “wlan0”). Not sure if it is 10.10’s doing or of
unsuccessful attempt to install Dirk’s drivers. Either way, it does not
work.

allenlan,

You seem to have a very buggy dsdt.dsl, I suggest you update your bios.
I am still looking at how to quirk the kernel to fix your button.

I'm using openocd with a Luminary Micro LM3S6965 board.  I hadn't used
it in a while - did a bunch of upgrades since the last time I used it.
Now, when I use minicom to open /dev/ttyUSB0, I see nothing unless
openocd is running.  When I run openocd, i see a steady stream of some
unprintable character - comes out as a <?> in my terminal.

[Bug 671155] Re: system crashes randomly, needing hard reboot

Victor Campos — 2010-11-05T03:17:13

I've been having this random crashing since I installed 10.10. In my
case, I did a new install using an old home folder.

Just today I started looking for the problem and noticed this post of
yours: https://answers.launchpad.net/ubuntu/+question/132340

I got there since my system crashed today and I say a few occurrences of
the pulseaudio error in /var/log/messages before the crash.

I'm kind of new into trying to solve a problem like this, but the
crashes are quite disturbing so I'm available to help. Ask anything and
I'll try my best to post the results from my machine.

Ross Nye — 2010-11-05T02:32:45

In the hope of getting the importance of this bug raised I'd like to add
that this bug is now stopping me from updating using the update manager.

When it tries to open the authentication dialog box I get an alert
window "Cannot grab Mouse". The only thing I can do then is close it
with Alt-F4. Update manager then goes back and refreshes the package
list and no update occurs.

Hi All,

I killed and started wpa_supplicant with more debugging and to the
terminal.  Here is the output from that after trying to associate eth3
with WIREFREEWWU (which has no encryption at all).  First is the command
sequence I used to do this and then some of the messages I copied from
the terminal.  Note that eth1 is an IPW2200 which works fine.

Chris Halse Rogers — 2010-11-05T01:46:52

< at >Don Thompson: Excellent debugging!  If you could subscribe to the
upstream bug at http://bugs.freedesktop.org/show_bug.cgi?id=29278 and
post that, I'm sure Jesse Barnes will be interested in that data point.
The only thing that might be useful before doing that is to check that
it's not fixed in the drm-intel-next kernel ( http://kernel.ubuntu.com
/~kernel-ppa/mainline/drm-intel-next/ ), as there have been numerous
partial fixes accumulating there.

If you'd prefer not to subscribe to the upstream bug, I can forward your
results on.

[Bug 671240] [NEW] ath9k locks kernel in 10 ms,causing e g audio dropout

David Henningsson — 2010-11-05T01:37:58

Public bug reported:

I'm using Jack and trying to get low latency with the generic kernel.
I've been using the wakeup_rt tracer to try to hunt down the xruns, and
the result points toward the ath9k driver. The basic question is that
this computer has four cores (two cores with hyperthreading), so why
would ath9k block the audio in the first place - shouldn't it just run
on another core?

[Bug 669399] Re: Touchpad bottom edge unresponsive in ubuntu 10.1064-bit

Alan Nise — 2010-11-05T01:21:13

< at >juliobahar.

I am able to scroll correctly on my computer. The issue you are having
may be configuration related.G-pointing devices is a bit tricky to use
(even when everything is working perfectly) Here are some things to
check:


1) Its my understanding that g-pointing wont even work unless you add the SHMConfig On option to your xorg.conf file. Basically without this the synaptics driver cant have its options changed during runtime. This is my /usr/share/X11/xorg.conf.d/50-synaptics.conf file..

Section "InputClass"
        Identifier "touchpad catchall"
        Driver "synaptics"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Option "SHMConfig" "on"
EndSection

note the last line . .. this is required ..

2) I dont think that changes made with g-pointing devices will be
effective at startup, or after sleep without some scripts installed.  If
you want to mess with it check out
https://help.ubuntu.com/community/SynapticsTouchpad.

3) Personally I found it easier to deal w

Yes,  the workaround for this bug is something that a novice can do. When

report. One warning: your graphics will suffer. But, I've found this to be a
small price to pay for suspend.

I think it would be very worth it to spend some effort on this--

one. (and one that's slightly unix-friendlier)
