Openchrome (1:0.3.1-0ubuntu1) crash system after start X

[Rodrigo Miguel]

When you start Ubuntu / Xubuntu / Lubuntu 12:10 or 13:04 (Beta), the system hangs before loading the graphical environment (system freezes with the screen totally black).

My video device:
01:00.0 VGA compatible controller: VIA Technologies, Inc. CN896/VN896/P4M900 [Chrome 9 HC] (rev 01)

The Ubuntu installation is only possible using the parameter xforcevesa in GRUB from Live CD / USB. After installation you need to configure xorg.conf to load the VESA driver and to start with the correct resolution.

Bugs have been reported:
https://bugs.freedesktop.org/show_bug.cgi?id=58409
https://bugs.freedesktop.org/show_bug.cgi?id=53307

Fixed:
https://bugs.freedesktop.org/show_bug.cgi?id=53307#c21

I compiled the version of Git and solved the problem. I would ask that the fix was included in the repositories.

Xorg log

Upgrading from 0.2.906 to 0.3.0 causes the system to become unresponsive (including SSH sessions). Reverting back to 0.2.906 works as expected.

Watching Xorg.0.log and dmesg during "startx" on remote via SSH with tail did not create any output but I will provide what I can.

Attached is the complete Xorg.0.log. Although it mentions 0.2.906 I was using 0.3.0 at the time of the log creation (unless somehow the log is still from 0.2.906).

Please let me know if I am missing anything obvious and I will provide it. I have no .xsession-errors file.

[Xavier-3a (xavier-3a)]

This log really is from 0.2.906. Can you please provide the 0.3.0 log ?

[Jsimmons-t (jsimmons-t)]

From reading the bug report from Arch linux I get the impression you attempting to run with the new drm KMS driver. Is this true? Can you attach your dmesg log.

dmesg

[Hungryhungryhobos (hungryhungryhobos)]

Apparently no Xorg log is actually created with 0.3.0 upon "startx" and then subsequent system freeze. Attached dmesg, but I'm not sure how useful it will be since I can't "startx" and there is no mention of drm.

[Bartosz Kosiorek (gang65)]

Please build the latest openchrome from git master and try to reproduce this problem.

[Bartosz Kosiorek (gang65)]

Please also follow following instruction:
http://www.x.org/wiki/Development/Documentation/ServerDebugging#The_basics

1. Run X.org
2. Go over to your second machine and ssh into the first one. su root
3. gdb /usr/bin/Xorg $(pidof X)
4. try to run "bt"

[Hungryhungryhobos (hungryhungryhobos)]

I can duplicate the issue with current git-master (803c882) using libdrm 2.4.39 and libxvmc 1.0.7. As soon as startx is issued the machine becomes unresponsive including the ssh server and any existing sessions.

[Bartosz Kosiorek (gang65)]

Try to disable hotplugging, by following instruction:
https://wiki.archlinux.org/index.php/Xorg_input_hotplugging#Disabling_input_hot-plugging

[Jsimmons-t (jsimmons-t)]

Does this problem still exist?

line compare fix

This bugs very familiar to the one we saw in the DRM KMS driver. Can you try the attached patch to see if it works.

[Hungryhungryhobos (hungryhungryhobos)]

The problem still exists. I tried disable hotplugging and the attached patch, but I won't rule out user error/ignorance. However, this laptop has encountered another video related issue beginning with kernel 3.5.4 (and still present as of 3.6.8). The laptop screen becomes garbled during boot but using external monitor still works.

This was one of the least Linux friendly machines I've used, and at this point I'm ready to send it away. Would it be useful as a development machine? I can mail it to an interested developer.

[Jsimmons-t (jsimmons-t)]

I hate to see you lose your hardware. How about you email me privately and we can discuss me getting access to your device and fixing it.

[X-conquistador-x (x-conquistador-x)]

did you resolve problem? may be I have same bug
bug: 58409

[Jsimmons-t (jsimmons-t)]

Not yet. I'm attempting to get my hands on some of this hardware to reproduce the problem.

[Jsimmons-t (jsimmons-t)]

Hardware is expected around Janurary 14th. Once I get it I will work on the problem.

[Xavier-3a (xavier-3a)]

*** Bug 58409 has been marked as a duplicate of this bug. ***

[Xavier-3a (xavier-3a)]

This should be fixed in git master, can you please give it a try and report back ?

[X-conquistador-x (x-conquistador-x)]

Sorry for such long answer
I have not this hardware anymore. When I will get it again, I will test bug

[boenki (boenki)]

I can confirm this bug is fixed in git-mainline-master.
I was affected by this bug since 0.3.x came out. Now I built it from git and it works again. Thanks.

[Hungryhungryhobos (hungryhungryhobos)]

Which git commit fixed this? It would be useful for downstream.

[Jsimmons-t (jsimmons-t)]

Since it works we can close this ticket.
