Gayathri's questions

I have an HP dv laptop running ubuntu 11.10 and gnome 3 DE. I've gone through a couple of posts here and followed the instructions given in this thread on ubuntu forums - http://ubuntuforums.org/showthread.php?t=1515562

This is the instruction given in the troubleshooting part of the thread(because nothing else worked for me)

cd Desktop

git clone git://linuxwacom.git.sourceforge.net/gitroot/linuxwacom/input-wacom

sudo apt-get update

sudo apt-get install build-essential libx11-dev libxi-dev x11proto-input-dev xserver-xorg-dev libxrandr-dev libncurses5-dev autoconf libtool

sudo apt-get upgrade

uname -r

(If you have the generic kernel which most do.)
sudo apt-get install linux-headers-generic

(If you have the rt or pae kernel.)
sudo apt-get install linux-headers-rt
or
sudo apt-get install linux-headers-generic-pae

cd input-wacom

./autogen.sh --prefix=/usr

(If you are in Lucid or Maverick.)
sudo cp ./2.6.30/wacom.ko /lib/modules/`uname -r`/kernel/drivers/input/tablet/wacom.ko
or
(If you are in Natty or Oneiric.)
sudo cp ./2.6.38/wacom.ko /lib/modules/`uname -r`/kernel/drivers/input/tablet/wacom.ko

sudo depmod -a

I just can't get the sudo depmod -a part given in the instructions to work. When I do that, my output is like this -

gaya3@kikyo:~/Desktop/input-wacom$ sudo cp 2.6.38/wacom.ko /lib/modules/3.0.0-15-generic/kernel/drivers/input/tablet
gaya3@kikyo:~/Desktop/input-wacom$ sudo depmod -a
WARNING: Can't read module /lib/modules/3.0.0-15-generic/kernel/drivers/input/tablet/wacom.ko.gz: Exec format error
gaya3@kikyo:~/Desktop/input-wacom$

Also, my tab is detected as shown by running lsusb

gaya3@kikyo:~$ lsusb

I don't know whether I messed up by doing the instructions over and over again. =(

I'm using a hp dv4 running Ubuntu 11.10. The sound is fine when the speaker is on and the volume control works fine too. But when I plug in the headphones, the sound gets muted. Even if I change the volume to max, the indicator LED show's that its muted. Is this a bug?

The display brightness comes down 2 shades darker if I'm idle for 10-11secs!! It automatically dims itself :o and it's very distracting!

Earlier this could be avoided through power management, by the "dim display brightness while idle" setting and setting the time limit. Now, apparently, it's not available there?

Is there a way out?

I have a HP pavilion dv4 laptop and the card reader just doesn't work :o it used to work in 10.04 though... but it doesn't seem to be working here. Went through many other threads but everybody is saying "it just works out of the box"... :( sadly it doesn't for me... help!

I have an hp dv4 laptop running Ubuntu 10.10. While booting up, the laptop fan just runs excessively for a few seconds until the login screen appears. Then it functions normally for the rest of the session.

I've read somewhere that you can do some tweaking in boot options. When I checked it out it was given laptop fan always ON : Enabled so I disabled it. Now, while running the system the fan alternatively picks up speed and then slows down.

The laptop is not hot at all and the temperature is a bit cold here. Any help will be appreciated :)

I'm using Ubuntu 10.10 on an hp dv4 and my wifi was working just fine(except the wifi led blinking) till yesterday. Now when I touch the wifi button it just won't switch ON!!! :o I didn't make any changes yesterday but updated my system today.

I have no idea what happened. Any clue???

I ran the command sudo lshw and got its output as:

The network is disabled?!? :o i tried to enable it by right clicking on network manager but the Enable wireless button has been greyed out.

I opened the file /var/lib/NetworkManager/NetworkManager.state and found that the contents are

[main] NetworkingEnabled=true WirelessEnabled=false WWANEnabled=true

I tried to change WirelessEnable=false to WirelessEnabled=true but after reboot it resumed back to the same state.
