** Description changed: - Running Lucid Alpha with todays updates I have some interesting visual - effects: + Ubuntu Lucid Lynx, kernel 2.6.32.xx - Zooming in with Super+Scroll causes the screen to become very dark. It - looks like the backlight on the display turns off, but I'm not sure. - Adjusting Fn+Brightness doesn't fix this, although I can tell the - brightness changing slightly. The same thing happens when changing - workspaces (Ctrl+Alt+-> or Ctrl+Alt+<-), dragging a window from one - workspace to another, or using Expo (Super+E) to view all workspaces - simultaneously. Returning to normal zoom level will always restore the - correct level of brightness, corresponding to how it might have been - adjusted during black out. + Zooming in with Super+Scroll causes the screen to become very dark, + practically unreadable. Adjusting Fn+Brightness doesn't fix this, + although I can tell the brightness changing slightly.

I + also noticed that the cursor will stay bright against the dark + background. - I'm reporting this against the kernel and not the display driver because - the bug goes away when testing the mainline kernel (which AFAIK does not - use modesetting by default) and by appending nomodeset to kernel boot - parameters. + I reported this bug against the kernel because with the mainline kernel + there were no issues with brightness (albeit, there are some other + issues).
