Package: kernel-image-2.6.7-powerpc Version: 2.6.7-4 Severity: normal Hi,
The radeonfb driver on my iBook does not bring the display back properly after sleeping. After sleep the backlight turns back on but the display remains completely dark. I have had this problem with the old and the new radeonfb driver and various 2.4 and 2.6 kernel versions. This problem started after I sent the iBook back to Apple about 10 months ago. I think the motherboard was replaced at that time. If I disable suspend to state D2 [1] then resume works as expected. Other notes of interest: - I tried to find the culprit in drivers/video/aty/radeon_pm.c:radeon_set_suspend() by selectively removing parts of that function. I did not find a combination that improves the situation. - I tried twiddling with the backlight keys after sleep. I can turn the backlight off, and back on, but the display remains black. - I tried switching between console and X, to different consoles, and back, etc. The switching works, apparently, but still a black display. - OSX successfully brings the display back after sleep. I don't know how to tell if OSX is putting the chip in state D2. Any clues for other things to try? Thanks, David [1] : This patch allows my laptop to sleep and resume as expected.
