I've been using Ubuntu as my main system since 7.04 with a few short breaks using Windows or Fedora because of temporary hardware/software incompatibilities. I support FOSS projects like Ubuntu for a number of reasons but the biggest one is that the software works and it works well--often better than the non-free alternatives.

I'm no guru but in my travels I've learned a thing or two about using/debugging/fixing problems in Ubuntu which I'm always happy to share with the community. If it hadn't been for the help I've received from the Ubuntu community over the past few years I probably wouldn't have gotten past my first month of using it much less to where I am today!

comment Laptop turns off completely when watching flash video(s) online. How to fix it?
I'm not going to speculate, but if you could verify whether the fan is working (both in Windows and Ubuntu) that would make diagnosing what's wrong much easier. If you can boot into the Dell Diagnostics partition, that also has a utility to test the fan.

comment How do I get 1366x768 resolution with dual graphics card ATI Madison Radeon HD 5000M Series and Intel Integrated Graphics Controller
Can you please post the output of lsmod? And tell us what, if any, proprietary drivers you activated in Jockey (Additional Drivers) or otherwise?

Sounds like it is overheating and automatically shutting off to protect the components. Check to see if your fan is broken.

comment Are there any applications that map and show the health of the hard disc?
It's called Disk Utility. It's very useful, especially since it lets you quickly and easily see the SMART info for the discs.

comment Is Seagate's new “FAST Factor Boot” technology compatible with Ubuntu?
I bought a new laptop with this hard drive so soon I'll be able to definitively answer the question.

comment If I enable ufw, and disable ssh. Is my base install Ubuntu 12.04 safe from the outside world?
What do you use the machine for? Making a local fileserver safe, making a webserver safe and making a desktop computer safe are all very different topics--especially since the most dangerous component of the latter setup is the human operating it.

comment Mail Server not working?
I think I found one problem while editing the code tags in your post " smtpd_banner = $myhostname ES..." begins with a whitespace (it was messing up the code tags here which is how I found it!). Try editing /etc/postfix/main.cf and removing that whitespace and see if it helps at all.

comment wordpress restored from backup asking for ftp
Glad it worked, but I'm not sure how good having them owned by the user www-data is... I usually just have them owned by the group www-data.

comment wordpress restored from backup asking for ftp
I'm not familiar with Wordpress but it doesn't surprise me that it requires ftp access to install a plugin--otherwise you would be giving your webserver permission to create/delete files... A bad idea. On another note, you probably should have your files owned by root. Have them owned by any old user and then giving the www-data group (Apache) read access is much more secure. I've had great luck using vsftpd for installing/updating Drupal modules, if you desire I can give you some info on how to set this up.

comment My notebook does not detect cable VGA
Some notebooks will have a hardware key combination for switching to the VGA output. On my notebook this combination is Fn+F7.

comment System Needs Tuning
@Kiwifrog If it's just the SSH connection that is slow, it could be the internet connection (on your side, or the server side, or somewhere in between) that is running slow. SSH involves encrypting your commands, sending them across the internet, decrypting them, executing them, encrypting the output/result/response, sending that back across the internet, and then finally decrypting it so you can see it. It's always going to be a bit slower than running things natively.

comment How do I get Ctrl+Alt+F* virtual terminals to work in Ubuntu 12.04?
These work for me in 12.04, so it sounds like you might be experiencing a bug. Do you notice anything interesting in your logs when you attempt to load one of these sessions?

comment How to get sound in a separate X server in Ubuntu 11.04 or later?
I'm guessing you would need to have the output of the pulseaudio server (or whatever sound server you are using if not pulseaudio) on the second xserver routed as an input to the pulseaudio server on the first xserver--this is because only one audioserver (or, if you aren't running an audio server, only one application) can access the soundcard at a time. I'm not sure off the top of my head how to do this, but hopeful it gives you an idea of where to look (the pulseaudio documentation).

Are you talking about the WUBI installer here? If so, it looks like there is a bug with the website.

comment Was using Ubuntu 12.04 LTS, working fine. now have only Grub prompt. What do I do now ?
Hi CJK. You can boot into Ubuntu from a grub> prompt but it can be a little complicated, especially if you don't remember what your partition table looks like. If you have access to a liveCD you can use the method in this Q&A and it should fix the GRUB for you. If you don't have a liveCD or have problems please post as much and we will find another way.

comment Why do the Nouveau drivers work better than the Nvidia ones?
Well they are open source, and therefore the Linux community can fix bugs themselves rather than waiting for Nvidia.

comment Intel Ivy Bridge Z77 Driver for Ubuntu 12.04
Please note that the GPU not being identified in System Settings is a bug and can be safely ignored--even if the GPU is recognized and working perfectly it will still not show up in system settings.
