KMS problems on macbook2.1, both in VT(minor) and Xorg(freeze)

[TobiasTheCommie]

Binary package hint: xorg

With kms enabled + bootsplash:
- Everything looks fine and dandy, untill X loads. When X loads the mouse cursor is very garbled(is only recognizable as such because it moves), and nothing else is showing on the screen.. ctrl+alt+f1 does nothing. Caps-lock, etc, aren't responding.

With kms enabled, no bootsplash, VT only:
Resolution is changed. It looks great, and is very fast, but parts of the very bottom of the screen (1-2px) is filled with garbage.

More information in comments.

With kms disabled:
Everything is working fine.

If i, during an kms disabled, run
sudo /etc/init.d/gdm stop
sudo rmmod i915
sudo modprobe i915 modeset=1

i will get the garbled pixels in the bottom of the VT. And a

sudo /etc/init.d/gdm start

Will fail just as normal.

For some reason i can't explain, the Xorg.0.log.old file contains stuff like this after the crash:

In another test it appears i got udev information in my Xorg.0.log.old after the crash

[TobiasTheCommie (lp453452)]

-- UPDATE

With kms enabled, no bootsplash, VT only:
Resolution is changed. It looks great, and is very fast, but parts of the very bottom of the screen (1-2px) is filled with garbage.

--- THIS IS WRONG
--This garbage is there even if the text on the screen hasn't reached the bottom yet. Is there after a "reset" command.

The garbage is a replication of whatever is on the last line of the VT... Doing a sleep 10, will result in a normal cursor on the bottom left, and weird copies of the cursor about every 10 chars to the right.

If there is more data on the bottom line(for instance, the normal prompt, or a file list) there will be more garbled date to the right of the cursor.

A reset fixes the issue.

Here is a dmesg from my testing of that

[TobiasTheCommie (lp453452)]

During my second test i ran a for loop saving dmesg outputs while i started gdm.

dmesg outputs 1-4 looks fine(as the one i just posted). This is before Xorg started.

dmesg outputs 5+ looks like binary data. I have multiple stored, and call always generate more, but here is one copy.

[TobiasTheCommie (lp453452)]

I would normally have filed this under Kernel, and not xorg. but https://wiki.ubuntu.com/X/KernelModeSetting said i should file it under Xorg.

I hope i have provided enough useful information.

I will be in vegas from tomorrow till tuesday next week, so i will not be able to provide any further information during that time.

Sincerely
Me

P.S. Sorry for the flood

Have a look at:

https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/393455

Apple hardware, pci 27a2 bus ID, similar symptoms.

May be related; there's a patch linked at the end to see if it fixes things.

[Robert Hooker (sarvatt)]

Do you have this problem with the 2.6.31-2? It has the upstream kernel fix for this situation in it and is related to EFI and not the specific intel device.

[Henrique Ferreiro (henrique-ferreiro)]

For me, kernel 2.6.31-3 fixed the problem.

The only problem I have is the pointer flickering when it turns into a spinning circle.

[TobiasTheCommie (lp453452)]

I'm still not home from vacation, will check on tuesday when i get back home

[TobiasTheCommie (lp453452)]

Ok, it is now resolved.

Good work
