I just installed 12.04 Alternate for the first time to give it a try using a USB stick burned with UnetBootIn.
It installed without a problem. But it booted into a
tty1 console without booting into a GUI.
After logging into the
tty1 console, I typed
unity. It appeared that the system doesn't have unity desktop. How can it be solved? My installation didn't show any error.
Something worth mentioning:
During installation, I had to choose an option saying 'customize the system to your needs' something like that I don't remember correctly with options 'SSH server','Mail Server', 'Ubuntu Desktop',.....,'Manual selection of packages' etc. I chose 'Ubuntu Desktop'. I haven't encountered something like this in 11.04.
To do an installation of Alternate iso using UnetBootIn, i used '12.04_Hdmedia' option of that software and had to change file extension of .ude to .udeb in /pool/main/l/linux that i found in Alternate ubuntu cdrom detect to go around with the cdrom detection problem.
I have a 945G intel graphics.
