Acer monitor AL2216w 1680x1050 cannot do anything execpt attach different monitor.
This started happening after latest system update. Reloaded Ubuntu back on hard drive still did not help. Took out one of my Nvidia video cards and still nothing. Attached different monitor and it detected that monitor and started working. I could log in and update the system, but switching back to old monitor still doesn't detect.
The monitor shows the bios screen has green light and then after cursor in the upper left cornor goes away the screen turns black and the button color turns to yellow.
Video cards are nvidia 8800gtx. Currently only running 1 card but would like to go back to SLI mode.
