i got 16 ubuntu updates this morning. i installed them. i restarted my computer, like i was asked. now my asus monitor insists there is no hdmi signal. im using vga.

however, i manually turned my zotac zbox on and off a few times. on hdmi, i get the "Zotac ZBOX" screen, then a dark purple screen, which i thought was a part of ubuntu's start up, then it goes black and says no hdmi signal. ugh. do i need a new driver or something?
