System Freezing Up on Nearly Fresh Install

[Xplorer4x4]

I am starting a new thread because I now have a nearly fresh install of Kubuntu(Precise). So far I have sudo apt-get update/upgrade, rebooted, added kde-goodies but have not installed anything from it. I have added the kde firefox ppa and installed firefox and kmozilla helper. I added the icon only task manager replacing the default task manager widget. I added the trash can widget to the panel, removed the activities widget from the panel, I marked dolphin, firefox and konsole to show launchers when not open. Thats it, literally a nearly fresh install with no real tweaks and the system still freezes and it is actually worse then before reinstalling! I can't even launch firefox with out the system completely freezing or partially freezing(such as a single app not responding). Any ideas on how to make the system stable?

I have to suggest, doing a fully 'clean' install of a totally 'default' 12.04. Absolutely nothing else. No PPA's. Nothing. Nada. Ensure that it works 'vanilla' first. Then, and only then, make 'one' change at a time and then reboot. Evaluate and document.

What about apt update/upgrade? Should I run it or not?

Sure. Fresh (formatted partitions) of a current 12.04 LiveCD. Reboot. Then, sudo apt-get update and sudo apt-get dist-upgrade. Nothing else. Test and ensure that all works. Then, and only then, make your changes -- ONE at a time -- and reboot and test.

Reinstalling now. Live cd burnt yesterday and has the newer installer(could have sworn kubuntu used a rethemed Ubuntu installer). If I do another reinstall should I Install third party software? This time I checked it.

I wouldn't install 'third party' software. I don't. I install 'later'.

I updated, rebooted, and then it prompted me to update the kernel and HP printer drivers. http://i.imgur.com/53a9g.png I noticed a quick freeze just after booting up after installing those. However I have been able to browse around quite a bit with no freezes so far. Do you suggest making KDE tweaks first before proceeding to install packages?

It haunts my T520 something terrible, and no amount of kernel fiddling makes it go away. I can reliably trigger the freeze whenever I make a call on my VoIP with a USB headset.

Interesting..you may be on to something, but I don't know if this is the same issue. From the way firefox is described in the second link, I have been noticing text disappear from my posts but reappear if i highlight it with the mouse. However, I have only started noticing this more recently, while the freezing was a long term issue. Does xorg utilize the intel video even when using a dedicated gpu? I was under the impression the gpu portion of the cpu was disabled when using a dedicated gpu?

Those bug reports have become nearly useless because they encompass such a wide variety of systems.

On my T520, the nVidia GPU is disabled in the UEFI, thus Linux never sees it. My X1, which doesn't have a dedicated GPU, has never once frozen. Personally, I think there's a weird problem involving switchable graphics and the kernel's USB subsystem. Witness the number of reports describing causing crashes with a ramped-up GLXGears script or by moving an external USB mouse around a lot. That would be a truly nasty bug to bisect out.

Are there any logs that might be usefull in narrowing down the root cause? I have checked the x-session errors previously, and it was of no use. I chcked it now and found alot of errors which I thought was strange from a still vanilla system(aside from adding wallpapers using the built in downloader and manually. http://paste.ubuntu.com/1115243/

I am curious to hear more on this theorey. If you could prove it to be true, atleast it is a step in the right direction. I would test, but sadly do not have a video out on my mobo which further makes me think that the intel video would be disabled automaticly. How would I check for the intel xorg drivers? I have dug around numerous places and everything I see points only to the xorg raedon drivers.

So far so good! I have only installed a select few programs and some small system tweaks. I was looking to install Teamviewer 7 as I use this for remote desktop from my phone to pc but I am hesitant because when I run apt-get -f install to gather dependencies, it wants 80MB and maybe 40 or more packages. Also, any time I try to run apt-get install somepackage, it keeps telling me to use apt-get -f install. I dont think teamviewer is actually installed though. How can I fix that so I can install other packages and not be force to install the teamviewer depencies? Just try dpkg -u teamviewer7? I just remembered teamviewer for debian/*buntu is actually the windows binary with a custom made wine wrapper(so it seems). Would that explain the huge list of dependencies?

Also whats a good back up program with an easy way to restore? I used kbackup to back up my previous install in case I forgot to grab some important files, but has no restore option. Ideally I would like something comparable to arconis true image home.

I had to uninstall firefox and kmozilla helper from the kde goodies ppa. I was having the same issues but not anymore.

[Xplorer4x4]

I am using the offical firefox atm and it seems to be working fine. In the previous install though, kde-firefox was one of the very few packages installed...

Something else that I just remembered..in my previous installs, I had RAID turned on in BIOS. However, I did not have an actual RAID array installed. It was more for preparation. This time around, I choose to use AHCI. I could have used IDE as well and according to a lot of old forum threads that appeared in google IDE was the better method. However, these threads were all from the likes of 2008 and 2009. So far, I have not seen any performance issues while using AHCI and wonder if using RAID might have caused a conflict the last time around. For those not familar with my old thread, the conclusion was it must be software related because I could create a new user account and not experience any system freezes,
