12.10 interview questions
Top 12.10 frequently asked interview questions
I have an Asus K55V and I'm wondering which version of Ubuntu I should be attempting to use. The website offers 12.04 (LTS) and 12.10.

I upgraded from 12.04 to 12.10 with no problem. I am trying to edit the grub file, but in the console I get the following message:
Fontconfig warning: "/etc/fonts/conf.d/50-user.conf",
line 9: reading configurations from ~/.fonts.conf is deprecated
As a result, I see nothing when the editor opens. Is there a fix for this? I can't find much information on Google.

I can not use chkconfig tools in Ubuntu 12.10
It's a very useful tools to configure the service to autostart or not. Why is it no longer available?

A software upgrade broke, among other things, mysql and I have not been able to get it back up yet.
Suspected cause: I had a near-full boot disk; the upgrade filled up the disk before completing and thus left everything in a mess. I have given the system more disk and moved /var to its own partition. I am still unsuccessfully trying to revive mysql.
Below is what I attempted so far (all as root).
First, mysql does not start (443). Attempts to fix (444, 445) fail. Attempts to remove mysql and (?) apparmor fail (446, 7, 8). A more energetic attempt to remove mysql seems to succeed (449) and the previous errors are no longer seen (450, 1, 2). Mysql can't be reconfigured because it's no longer there (453) but attempting to reinstall it gives back the old error messages and we're back to square one (454).
I also checked this question (even though in my case it did not break because of an upgrade to 12.04: it was already working on 12.10)
Fixing broken myslq-server package after upgrade to 12.04
and tried the suggestions in there (458, 461, 462) to no avail.
What else should I do?

I enjoy using Lightread in Ubuntu 12.10. The thing is Google Reader is being shutdown and Lightread is a client for Google Reader, so it's feed will be cut of.
What is the best alternative as a RSS reader for Ubuntu 12.10?

I have GeForce GTX 560 Ti. I's worked fine in 12.04 with nvidia drivers. Unfortunately, after todays 12.10 update, something broke down.
I've tried nvidia-current, nvidia-current-updates and nvidia-experimantal. Always the same behaviour: Bad resolution in lightdm, after logging nothing except wallpaper. No unity panels, "win" key doesn't work.
After removing nvidia drivers everything work.

I updated the Nautilus to 3.6 in Ubuntu 12.10, but I didn't find the how to add my folder to "Bookmark" section.
If I press Ctrl + B, it show the list of bookmarks, but I can't add any. I can't drag & drop just like in other versions.
Does anyone know how to do this properly?

I have a Debian image setup on Virtualbox that uses the default NAT to access the internet. It was working fine before I upgraded to 12.10. After I upgraded the DNS lookups no longer work. I still can access ip addresses, but this is not a nice solution.

As reported by Phoronix, the news from UDS appears to be that development on Unity 2D will stop, with the focus being on a single, unified implementation.
Obviously maintaining two codebases to do the same thing is not ideal. However, Unity 2D was created for a reason ("Unity 2D's goal is to provide the Unity desktop shell on hardware platforms that cannot currently support Unity's OpenGL requirements"). Why is it no longer felt Unity 2D is needed?

I've been looking at other questions, but none seem to answer my query. The closest I got gave me information about a ppa for 12.04. My computer's battery life is suffering under Ubuntu 12.10. I imagine the performance will be better if I use LLVMPipe, as it is aimed at lower end computers. How do I enable LLVMPipe?
I might add that going back to 12.04 is not an option, as my computer only works in Unity 2D, which didn't quite do it for me. As far as I understand, LLVMPipe is pretty much the same as regular Unity. However, I can't seem to find much information about it. If this is wrong, correction would be much appreciated.
