Description Kai Willadsen 2009-03-16 13:51:19 EDT
Using the live CD image linked from
X hangs at GDM. Prior to GDM, the system appears to correctly mode switch during plymouth (judging by text size, etc.). At GDM, the wallpaper is sometimes painted, while other times the background is black. The cursor can be seen and moved, but is corrupted. The system is unresponsive to a VT switch.

As an aside, booting with nomodeset the system does not reach GDM, and in fact doesn't even seem to attempt to mode switch.

The system is a first-generation Macbook:

Tested with latest rawhide on MacBook 2,1

Kernel 2.6.29-21.fc11.x86_64 

After boot machine locks at login screen - sometimes with background drawn and corrupt mouse pointer, sometimes a blank screen with corrupted mouse pointer.

Tested booting into run level 3
Tried startx from command line
X starts and locks at black screen with corrupted mouse cursor
Machine has to be powered down to reset.

Attached Xorg logfile Xorg.0.log.aic

Retested with F11 beta on Macbook 1,1. KMS appears to work in so far as the plymouth graphical boot works, and appears to be at the correct resolution. However, the machine still locks at GDM with a corrupted (but moveable) mouse cursor. The background draws, but the login box is just a grey rectangle. VT switch doesn't work.

Can you give the output of 'lspci -nn'? I'm suspecting this may well be the same adapter as the Mac Mini, https://bugzilla.redhat.com/show_bug.cgi?id=494390 ...

lspci output - under F10 (not F11)

The output of lspci.

I took this under F10, not F11.
Comment 7 Adam Williamson 2009-04-17 12:49:34 EDT
Yep - same adapter: 8086:27a2 . That's the same chip, in two Mac systems - I think we can mark these as the same bug. There's a bit more info in that bug, so marking this as a dupe of that.
