Bug 17377

Using mesa and nouveau from git as of today (commits cd7d71f1 and 6dd8ad4e resp.), it manages a little better, but still doesn't start up correctly.

When starting manually, it initialises the screen which what looks like the familiar stipple pattern, except that there are about 100 almost horizontal black lines across the it. They're a single pixel high, and run for about 128 pixels along before dropping down by one pixel. And then it locks up, eating CPU in nouveau_dma_wait():

Xorg.log from current git

Xorg.log with current git, started from gdm.

When gdm starts the X server rather than me starting it manually, the failure mode is a little different -- I see the same corrupted background pattern, but this time I do actually see the cursor, which I didn't see before. And then it crashes (rather than needing me to hit ^\).

It seems to notice that it's locked up this time, and includes a fifo dump in the log.

The "potential workaround" in bug 17359 doesn't make any difference.

Xorg.log with working nv driver

The nv driver works; this is its log, for reference.

When running the current driver, I get this output from the kernel:

[drm] Unhandled PFIFO_INTR - 0x00000010
[drm] Allocating FIFO number 1
[drm] Unhandled PFIFO_INTR - 0x00000010
[drm] nouveau_fifo_alloc: initialised FIFO 1
[drm] Allocating FIFO number 2
[drm] nouveau_fifo_alloc: initialised FIFO 2
[drm] Unhandled PFIFO_INTR - 0x00000010
[drm] nouveau_fifo_free: freeing fifo 2
[drm] nouveau_fifo_free: freeing fifo 1
[drm] Unhandled PFIFO_INTR - 0x00000010

How's things looking with current drm git?

F11 snapshot works OK (starts up with mode set, get proper resolution, no visible corruption) on my nVidia Macbook Pro 4,1 - tested with nouveau.modeset=1. The nouveau test day live CD did not work - so if you have a Macbook Pro it would be worthwhile to test the F11 snapshot.

Yeah, F-11 is working for me on the MBP4,1, with certain caveats:

 1. I must use nouveau.modeset=1; otherwise the nouveau Xorg driver fails.

 2. I must not boot from EFI, otherwise modesetting fails (and then see #1)

 3. I can use VGA or DVI external output, but cannot switch between them. If 
    I've been displaying to VGA and want to change to DVI, or vice versa, then
    I need to reboot before it'll work.

I'm experiencing the same problem with git version from today and sony fz21e 

When kdm is starting, only the pointer is visible, harddisk is working pretty much... and after very long time, I can log in, but as soon as I open a window, the xserver is crashing

In the logs, I have a Unhandled PFIFO_INTR see attachment

corresponding xorg.log

Even if I don't know for what it is ;), I also tried to pass nouveau.modeset=1 to the kernel, but then the screen remains black, like off, no pointer, nothing... I guess no backlight at all...

Be sure to have fbcon loaded or built in before loading nouveau with kernel modesetting.

The behaviour have changed a little bit with the following version :
ii  libdrm-nouveau1                      2.4.12+git20090801.45078630-0ubuntu0sarvatt2 Userspace interface to nouveau-specific kern
ii  nouveau-kernel-source                0.0.14+git20090730-0~9.10~ppa1               DKMS source for the nouveau kernel modules
ii  xserver-xorg-video-nouveau           1:0.0.10~git+20090730+9b37bc9-0~9.10~ppa1 

Now I often have a grey screen with a lot of colored pixels, when I go to a terminal, and go back to x, the display is ok, but still crashing after opening any window...

xorg log 03-08-2009

I've forgott to say that as the screen is with grey and black lines, the pointer is displayed normally...

dmesg 03/08/2009 sony vaio fz21e

It works for me. I guess the bug has been fixed.
