I've found that using alt-tab when the screen blanks causes it to appear again
** Tags added: apport-collected natty running-unity ** Description changed: Since upgrading to 11.04, the screen size is no longer correctly determined on boot and the screen may go black after running for a while. Latter can be corrected by ctrl-alt-del, former by repeatedly logging off and on until the correct screen size is determined. No such problem with 10 or before. P.S GRUB gets the screen size correct.
