--- Comment #6 from Dmitry Timoshkov dmitry@codeweavers.com 2008-11-01 01:04:45 --- I don't see that the cursor in gedit stops blinking before gnome runs a screensaver or goes to sleep.
Not displaying a blinking cursor doesn't mean that the timer and other code responsible for that doesn't run anymore, so I don't see what you would buy from that. If the power saving is a priority that should be done at the system/kernel level.
