A severe bug has been detected on systems with nVidia graphic card + compiz. Its severity lays in the fact that when randomly triggers it completely freezes Xorg through compiz. This is not actually that tragic since you still can gain control to a console via the alt+sysrq key combinations (see my post on how to do it: http://aldeby.org/blog/index.php/gnulinux/sysrq-key-combinations-on-hp-pavilion-laptops.html ) and SIGKILL compiz process.

- Firefox 3.0 cannot load java plugin. This is caused by changed firefox plugin folders. As a workaround you can manually create the needed symlinks: if you use sun-java6-jresudo ln -s /usr/lib/jvm/java-6-sun/jre/plugin/i386/ns7/libjavaplugin_oji.so /usr/lib/xulrunner-addons/plugins/if you use OpenJDK-jre:
sudo ln -s /etc/alternatives/mozilla-javaplugin.so /usr/lib/xulrunner-addons/plugins/
- FIXED Currently Suspend (suspend to ram or standby) feature is broken. No way to resume after entering standby. However, pressing CTRL+ALT+DEL or the power button shortly you can make the system reboot normally. The problem once again is in the video subset since the kernel is running and backlight switched back on. The workaround for this issue has been released with pm-utils 0.99.2-3ubuntu2
- Hide mounted partitions desktop icons: ALT+F2 type in gconf-editor, navigate from apps > nautilus > desktop. Uncheck volumes_visible. This will, however, prevent also icons for external mass storage devices to appear.
- Mozilla Thunderbird interface (GUI) could be messed up when Lightning Calendar extension is installed and the following packets are missing, if you are experiencing such a misbehaviour:
sudo apt-get install gcc-3.3-base libstdc++5
- touchpad scrolling and tapping stopped to work. This happens when touchpad configuration is missing from xorg.conf. For instance check that sudo gedit /etc/X11/xorg.conf contains the following strings, in case add them and reboot:
Section “ServerLayout”
InputDevice “Synaptics Touchpad”
EndSection
Section “InputDevice”
Identifier “Synaptics Touchpad”
Driver “synaptics”
Option “SendCoreEvents” “true”
Option “Device” “/dev/psaux”
Option “Protocol” “auto-dev”
Option “HorizScrollDelta” “0″
Option “SHMConfig” “true”
EndSection
- at login you get prompted by an error message stating “language xx_YY does not exist: using system defaul”. This happens only if you’ve upgraded from Gutsy, to fix it simply remove from /etc/environment the LANGUAGE and LANG lines. In Hardy locale settings are being managed in /etc/default/locale This should display something like this for English language:
LANG=”en_GB.UTF-8″
LANGUAGE=”en_GB.UTF-8:en”

Travis Place,
you should have a closer look at xev output since there is no reason why only those two buttons do not work.
Of course the don’t by default, but you can always associate them. You may refer to this guide: http://aldeby.org/blog/index.php/en-hp-pavilion-multimedia-buttons-configuration-under-linux-linux-quickplay.html
I have found most of the info on this page to be very useful, but I am still having troubles with the touch sensitive buttons on my laptop. All of the rew/ffwd/pause/play/mute/volume buttons worked out of the box, but the DVD and Quickplay buttons dont work at all. I have tried running xev, to find their keycode, but pressing those buttons doesnt cause xev to do anything at all.. very odd. Any ideas ?
SUSPEND SOLUTION: I had to enable the proprietary NVIDIA driver
(System->Administration->Hardware Drivers) then do what is in this link.
http://blog.vaxius.net/?p=43 suggests to get suspend working. (The blacklist item
made no difference)
It works perfectly
the first time but displays a full gray screen each time after. This appears to
be a messed up login screen, so just
enter your password, and you are
returned to the desktop. Hope this helps.
Hi Aldeby,
Well, the error returned via prompt was something like “sudo: unable to resolve host nostromo”, being nostromo my host name. It was with that info that I found the workaround in ubuntuforums.org.
As for the mouse problem, I was just breaking my xorg.conf every single time, so I gave up and did a clean install (lame, I know! LOL). I installed a fresh kubuntu gutsy and everything is running perfect.
The impression all around ubuntuforums is that hardy is quite troublesome, so I think I’ll wait for the next LTS release.
Cheers,
D
David,
thank you for your appreciation!
I’m afraid I have never got in touch with your #1 problem (sudo). It would be interesting to see what is your terminal when you try to gain root privileges (i.e. you type sudo apt-get update.
Your second issue is definitely a xorg.conf misconfiguration. If you are still experiencing this problem you could send it me via the contact form.
The third problem should be related to some of the many many bugs that affected python.
I see you have performed an upgrade, maybe a clean install would help.
Cheers
Hi,
Firstly, thank you to aldeby for maintaining such a useful site.
Secondly, I’ve recently upgrade to Hardy and it’s been very very difficult. Probs I came across:
* Couldn’t run admin apps through the gui. Yes… that meant that synaptic, network manager, update manager, everything that needed root pass was broken. Found a work around in ubuntuforums… can’t recall the link, but it’s basically editing the hosts file in /etc/hosts and remove the MS domain name.
* Wireless USB mouse not working. The touchpad is working normally, thankfully. I find the mouse plugged in, my feeling is that it’s something in the xorg configuration file, namely the server layout session. I’ve messed around with the config file a bit and managed to get the mouse to work again, but the card was no longer recognized so the screen resolution was all wrong.
* During the installation itself there was an error in the python bindings of tovid. It has been reported as a bug and I’m awaiting for some feedback.
Spec: HP Pav dv8k series T2400 @ 1.83 GHz, 1G mem, GeForce go 7400

There are actually just a few advantages with the 64 bit version noticeable only if:
- you have large amounts of RAM (>2Gb)
- do memory intensive works, i.e. virtualization, video editing, cad…
Advantages and Disadvantages of 64bit. (Plus install Guides)

Are you running the 32 or 64 bit version of Hardy?
Any real advantages to the 64 bit version?
I’m running 7.04 64bit now and don’t notice any real advantage.
Hey,
I tried all that. Still the machine does not get an IP. All the rest functions. I see all the networks. I have two other laptops with different chipsets running and two windows machines without a problem in my network. I thought it would be quit a challenge getting stuff like the tv card running, but the fun stops at this crucial thing. I also can’t find other posts about it.
I had the same in two different installs. I first tried 32bit and now the 64bit version. Which is nice and fast btw.
How can I troubleshoot it? It has got to be solvable.

Well, are you using hardy?
Intel 4965 is supported since Gutsy by iwl4965 driver at a basic level, however full featured support is provided only with Hardy with backports sources enabled.
On my laptop it worked flawlessly out of the box.
In any case you should definitely be able at least to connect.
Is the network manager applet set to ROAMING mode?
You should leave it this way.
Try disabling authentication on the access point.
If it gets the IP then maybe you are using WEP and have not chosen the correct type of password (hexadecimal or ascii).
If it does not get the IP even this way then open the shell terminal and type
‘ifconfig wlan0′
and see what address are associated with it.
then run
‘dhclient3′
which is the DHCP client aimed at obtaining the IP address from the AP.
