I recently installed a quantal on my T61 lenovo thinkpad. I previously had Windows 7 and an older version of ubuntu on the machine, but wiped both.
The problem I have is this. After I shut down my machine, the next time I try to turn on, when the bootloader is supposed to come up (on a purple background), the purple background appears for about 2 sec, then dissapears, and the computer hangs on a black screen. However, when I do a hard shut down from that and start again - everything works!
What would you recommend?
Previous ubuntu installs (~2011) have not had these problems.
