[Xpress 200] X Freeze switching from terminal to Xorg

[mmbossoni]

Binary package hint: xserver-xorg-video-ati

If I switch to a terminal (Ctrl+Alt+F1) and then switch back to the X server the system crashes and I need to manually reboot.

Hi mmbossoni-gmail,

Please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log (and maybe Xorg.0.log.old) file from after reproducing this issue. If you've made any customizations to your /etc/X11/xorg.conf please attach that as well.

I have no customized xorg.conf

Hi mmbossoni,

In your description you mentioned X "crashes" - is this correct or would it be more accurate to say it "freezes"? With a crash, X usually restarts itself; freezes lock up the system (sometimes only the mouse still moves). I ask because different approaches are used to debug each case.

[mmbossoni (mmbossoni-gmail)]

Freeze describes better the problem..
I cannot use keyboard or mouse.

probably a dupe of bug 23623. Does KMS work any better?

[Bryce Harrington (bryce)]

mmbossoni - I've forwarded this bug upstream to https://bugs.freedesktop.org/show_bug.cgi?id=23666 - please subscribe yourself to this bug, in case they need further information or wish you to test something. Thanks ahead of time!

Hi,
Enabling the KMS support make impossible to X to goes up.
Not even the logon screen appear

[mmbossoni (mmbossoni-gmail)]

Hi,
FYI, I've updated the package to the latest version available from my distribution (6.12.99+git20090825.fc74e119-0ubuntu2) and everything worked well.

[mmbossoni (mmbossoni-gmail)]

I forgot to mention that worked with both KMS and the X way.

Hi,

The only point is a power management issue when I switch from VT to X. If my laptop is working without AC plugged in, my screen bright goes to the lowest level.

[mmbossoni (mmbossoni-gmail)]

I forgot to mention that worked with and without KMS.

[mmbossoni (mmbossoni-gmail)]

Hi, appear the bug came back with the beta release.
radeon.modeset=1 keep things working well, but the X way keeps freezing.

What version or commit id ended up in the beta release?

[Bryce Harrington (bryce)]

The beta release was 6.12.99+git20090825.fc74e119, so up to commit fc74e119.

For the release we are targeting 6.12.99+git20090929.7968e1fb.

Marcelo, it would be helpful if you could update to the latest -ati in Karmic and confirm the bug is still occurring with that version.

[mmbossoni (mmbossoni-gmail)]

Updated to 6.12.99+git20090929.7968e1fb
Everything seems to work correctly now.
KMS with AC: OK
KMS without AC: OK
No KMS with AC: OK
No KMS withtout AC: OK

[Bryce Harrington (bryce)]

Thanks for verifying that.

[Bryce Harrington (bryce)]

According to your comment on the upstream bug report, this is now resolved in the latest version so closing this one as well.

[Matthijs Kooijman (matthijskooijman)]

I've been experiencing the same problem, and for me the problem is _almost_ gone (it's at least very workable right now, unlike before. Thanks for that.). I've tested the git revision mentioned below (7968e1fb) and the 6.12-branch of a few days ago (0db4b1708). Both versions show the same behaviour. I've only tested without KMS, I haven't got KMS set up yet.

I'm still seeing this problem (or at least a problem with the same symptoms) when I pull out or plug in the AC connector at the same time as switching from the terminal to X. The problem does not occur when switching from X to the terminal while changing the AC connection. This problem seems to occur pretty reliably (though not every time), so it seems the timing is not super critical.

This problem also occurs when I unplug the AC connector while the laptop is suspended to disk (e.g., when it's off). As soon as it desuspends and tries to restore X, it freezes. It seems that the kernel realizes the AC adapter is unplugged immediately after desuspending, and at the same time X is being restored. This does not happen when I manually switch to text mode before suspension and switch back manually (a while) after desuspending.

Marcelo, could you perhaps see if you can reproduce this?

[Matthijs Kooijman (matthijskooijman)]

It seems this bug is really a duplicate of 22140 (and is not entirely fixed yet).
