My monitor (Gateway FPD1975W 1440x900 res) has suddenly increased in brightness (or else lost contrast). This happened within the past couple of weeks. I cannot even see some things (for instance the text boxes on this page Under "Prefix" and "Title" and the boxes where I had to type my username and password to even get here were invisible. I am dual booted with Windows XP and am not having a problem there, so it looks like something in Ubuntu not the actual hardware. I have tried manually adjusting the brightness and contrast using the controls on the side of the monitor to no avail. I am also a newbie, so a lot of grep and grub stuff will just blow right past me.
