I have recently switched from Windows 7 to Ubuntu 12.10. I have installed Ubuntu 12.10 and I cleared everything from my computer, but it randomly stops at different screens.

Only a purple screen comes up.
I can choose Ubuntu from a list and a blinking white dot appears in the top left corner.
The previous things happen and the Ubuntu login screen appears an I can log in.

It is random. and I have not changed anything. I can always insert the bootable CD and it will work every time.

12.04 upgrade broke grub? (not wubi related)

as seen on Ask Ubuntu - Search for 'Ask Ubuntu'
I just updated from 11.10 to 12.04, with no major problems (it took a while to get past a request to restart ssh, mysql and some other services, but I did no fiddling by myself, everything was done by the installer). However, after restarting, grub can't do anything. Picking the new linux installation… >>> More

Will it be possible to use a non-pae kernel in 12.10

I know that Ubuntu +1 questions are frowned upon, but this I believe is a fair exception. Currently I have 2 systems running Ubuntu 12.10, and one of them has a Pentium M that doesn't support PAE (strange I know, but true). This has meant in the past that I had to rely on a custom iso to install… >>> More

How will people upgrade from 12.10 to 14.04 after 13.04 is EOL?

Looking at https://wiki.ubuntu.com/Releases 13.04 will reach EOL in January 2014, while 12.10 will reach EOL in April 2014, therefore if a 12.10 user hasn't upgraded to 13.04 and subsequently to 13.10, there will be a 3 month period where a 12.10 user has a supported version of Ubuntu, but will be… >>> More
