Mixxx with ATI graphics card (using FGLRX) crashes Ubuntu

[Alexander Dobetsberger]

I run Ubuntu 10.10 and installed Mixxx 1.8.0.1-1ubuntu1 from the Software Store!

When i try to start the Program my whole system freezes and i have to reset my computer!

If you need some logfiles, of further information, let me know!

[pschroth (philip-schroth)]

Same result here on ubuntu 10.10 amd64

[Albert Santoni (gamegod)]

Hi guys,

What are your videocards and videocard drivers?

Can you run glxgears without Ubuntu crashing?

In the Appearance settings in Ubuntu, do you have desktop effects turned on?
If so, does turning them off allow Mixxx to run?

Thanks,
Albert

[Alexander Dobetsberger (masternoob)]

* i use a ati 4800 series videocard with the newest fglrx driver from ubuntu
* glxgears runs with no problem
* standard settings, and turning the desktop effects off does not solve the problem

[Seven Roots (sevenroots)]

Ditto on the Mixxx starting up problem.
Running fresh install Mixxx 1.8.0 on Maverick Meerkat 10.10 amd64.
Trying to run mixxx, crashes ubuntu and logs me out.
Same as above - changing Appearance settings does not fix the problem.

[RJ Skerry-Ryan (rryan)]

Hi Artem N.

Could you please try adding the following lines to your ~/.mixxx/mixxx.cfg :

[Controls]
Visuals 1

This will disable the waveforms. Try loading Mixxx after making this change and let us know if it still crashes on startup.

Thanks,
RJ Ryan

[mrvica (malisha-serb)]

So, i did what you asked. It worked, Mixxx runs fine with disabled waveforms. Did that help?

[RJ Skerry-Ryan (rryan)]

Masternoob, Artem N.

Could you please try out the workaround and tell me if that works?

mrvica, what graphics card do you have ? Can you post the output of the `lspci' command?

[Albert Santoni (gamegod)]

Ok, so the common trend so far is ATI videocards. Have you guys installed an
updated fglrx driver from ATI or are you using the stock driver that came
with your distro?

This'll give us a better idea as to how widespread this problem is.

Thanks!

Another thing I've found that happens through testing is the following...

If I load a track with the waveforms disabled and then play the track it works as we know, if I then while the track is playing go to the settings the re-able the waveforms, the waveforms then work as they should and Mixxx doesn't go off. But then when I load another track into the other channel, as soon as it's played it then goes off within seconds of the second track being played.

Not sure if this will help but I thought I'd let you know.

Regards

Gary

[David Ordenes D. (radioboy-2)]

I have the problem in Ubuntu 10.10 (64 bits), using the ATI Catalyst driver 10.10; I got it from the ATI website.
My card is a Radeon Mobility HD3400.
I will try the modification to the config file this weekend.

[Peter Havekes (peter-havekes)]

No, the 'Visuals 1' didn't fix it for me.

[Gary Littlemore (gary-littlemore)]

Peter your problem is your graphics card

01:00.0 VGA compatible controller: ATI Technologies Inc M93 [Mobility Radeon HD 4500 Series]

It's an ATI, that's what's causing our problem

[RJ Skerry-Ryan (rryan)]

Hey Peter,

Can you please tell me exactly what you added to your mixxx.cfg ?

Was it :

[Controls]
Visuals 1

You need to add it at the end, or remove any other instance of "Visuals" from the file.

Please let me know if that makes the workaround work for you.

[RJ Skerry-Ryan (rryan)]

Also, if someone could try removing fglrx to confirm that it's related to the ATI proprietary driver, that would be great:

http://wiki.cchtml.com/index.php/Ubuntu_Feisty_Installation_Guide#Revert_to_Xorg_driver

[RJ Skerry-Ryan (rryan)]

From what I can tell, the commonalities between all of you are:

1) Ubuntu 10.10 (32bit and 64bit)
2) ATI Hardware (various types) with fglrx driver

Please comment if you are seeing this bug and have a different setup.

[Gary Littlemore (gary-littlemore)]

RJ I had this problem with Ubuntu 10.04 too.

Gary

[David Ordenes D. (radioboy-2)]

Mixxx has worked for me before with older versions of Catalyst (10.7) in Linux Mint 9, using compositing (Compiz in Gnome).
After changing to Ubuntu Maverick and Catalyst 10.10, it it crashes the complete system if compositing is enabled, but it works without issues if I disable it.

All this is in a Dell Studio 1535 notebook, with ATI Radeon Mobility HD 3400.

[RJ Skerry-Ryan (rryan)]

Thanks for info David,

Can everyone else try turning off Desktop Effects / compositing to see if this fixes the issue for you?

RJ

[Peter Havekes (peter-havekes)]

I've first updated X and ati drivers by using xunubtu ppa. That didn't help.

I initially added Visuals 1 to the existing [controls] entry in the cfg.file. Now I've deleted the existing [controls] section and added
[Controls]
Visuals 1
   to the bottom of the file, and now it starts and runs fine.

[Peter Havekes (peter-havekes)]

ps: I didn't need to turn off Desktop Effects / compositing

[Gary Littlemore (gary-littlemore)]

RJ,

My 'Visual Effects' is already set to 'None', so this is a no brainer for me.

Regards

Gary

[Gary Littlemore (gary-littlemore)]

Hi RJ

Not sure what 'fglrx' is or does but attached is the search for it in my Synapic Package Manager. Not to sure about the last one in the list it seems to have an '!' on the left.

Regards

Gary

[phil(nice) (philgood052)]

A little update from me: Mixxx 1.8.1 works fine the past two weeks. After the freeze, i went into my bios settings and everything was screwed big time. After fixing that, my computer doesn't freeze anymore even if mixxx runs with compiz. Just the normal misbehaves.

[RJ Skerry-Ryan (rryan)]

Hi phil,

Could you explain what you had to change in your BIOS settings to resolve the issue? Those will be important clues.

Thanks,
RJ Ryan

[phil(nice) (philgood052)]

Hi ryan,
Basically when that happened (two times in total so far), the on board graphics have turned from off to on or auto.
and all the settings regarding the graphics card, turned back to default. But notice that i'm currently on a very old system (asrock k7s8xe motherboard, and an sapphire ati hd 3650 agp card).
So, aperture size has gone back to default, (32M), and so the data rate for the graphics card. Again, i don't know if this information could help for a newer system.

[Peter Havekes (peter-havekes)]

The stange thing is when I append
[Controls]
Visuals 1

to the config file, mixxx starts perfectly. When running I can enable waveform display without problems. When I close and restart mixxx it crashes X. I need to re-edit the config to start mixxx again.

[Gary Littlemore (gary-littlemore)]

Does anyone know if we are any closer to fixing this bug?

[Peter Havekes (peter-havekes)]

Considering my previous comment I wonder what the difference is between 'creating' the waveform on startup, and creating the waveform after startup, when enabeling the option from the preferences. The waveform display itselve is not the problem.

Can the workaround be to alwas create the waveform display after the application has been started? So after the ui has been generated check the state of the visuals-option and then decide to draw the waveform area or not?

[Gary Littlemore (gary-littlemore)]

If I enable the waveforms after loading and playing the first track, it still shuts down when the next track is then played in the other channel.

[RJ Skerry-Ryan (rryan)]

OK I got ahold of a laptop with an ATI graphics card to test this.

With Ubuntu 10.04, on a laptop with an ATI Radeon HD3470 video card, with fglrx (2:8.723.1-0ubuntu5) from the Ubuntu repositories, if I turn on Standard desktop effects, then one of the Mixxx waveforms flickers severely and 'ghosts' if I move the Mixxx window around (i.e. the waveform does not move with the Mixxx window, it remains where it was originally created). If I rapidly minimize/expand Mixxx, eventually X freezes and I have to restart GDM. With desktop effects turned off, Mixxx (both the 1.8 branch and trunk) run perfectly.

While running the Qt examples, it looks like the 'textures' example shows similar results. This is likely because it is the only example that uses multiple OpenGL contexts.

For all of you, would you please install the package 'qt4-demos' and then run the following program:
/usr/lib/qt4/examples/opengl/textures/textures

Please report whether or not the program causes a crash similar to the way Mixxx crashes. That will help me determine whether or not we are dealing with a Mixxx bug, a Qt bug, or an fglrx bug.

Thanks everyone,
RJ Ryan

[Peter Havekes (peter-havekes)]

The textures program runs without any troubles,
I have:
- all desktop effects enabled
- ubuntu 10.10
- Mobility Radeon HD 4500 Series

I don't experience the 'ghosts' and other troubles when using waveforms in mixxx; the only problem is it craches X if waveforms were enabled on startup. If I anable waveforms when mixxx is already running it works fine.

[Gary Littlemore (gary-littlemore)]

Hi RJ,

I'm not to sure on the QT4, got it installed but couldn't work out how to run the 'textures'.

As for the 'fglrx' I'm not running it. See screendump

Not sure if this is going to help.

Sorry

[jus (jus)]

Current trunk crashes hard (even host machine) under Ubuntu 10.10 with Gnome in a VM on skin change, gt4-demo freeze the VM.
Interestingly the same VM with KDE does not crash, same for the gt4-demo although i have the ghost effects as described in #35 then.

@gary
After install simply put the line from comment #35 in the terminal and hit enter:
/usr/lib/qt4/examples/opengl/textures/textures

[Christian Medina (cmedinasoriano)]

Hi, I am a newbie so sorry if I miss some information.

I am currently working in Linux Mint 10 "Isadora" and had the same problems as described above. I uninstalled the 'fglrx' driver and restarted mint. After reboot Mixxx works just fine with or without waveforms (Visuals 1 or Visuals 0). I hope this helps.

[RJ Skerry-Ryan (rryan)]

Hi Christian,

Thanks for the confirmation and extra data-point. Could you please post the
output of `lspci' in a terminal? It'd be useful to know what graphics card
you have.

Thanks,
RJ Ryan

Tried again, this time with Catalyst 10.11 (Dell Studio 1535 notebook, ATI Radeon Mobility HD 3400, Ubuntu 10.10). I set Visuals=0 and I can use Mixxx without issues. The waveforms appear, with a few exceptions that I tend to suspect are related to the respective audio files instead of Mixxx.

[William Good (bkgood)]

Gary,
Could you post the output of `lsmod` (from a terminal)? That'd give the list of currently loaded drivers. I see that Ubuntu doesn't have fglrx (the propriety ati driver) installed but I find it very odd that you're having similar problems to all these fglrx users with a different driver (it seems that if there was another bad ati driver out there, we'd probably be hearing about that too), so I'd be interested in what driver the kernel actually has loaded.

Thanks,
Bill

[William Good (bkgood)]

Gary,
Thanks for getting back so quickly! Would you mind also posting the output of `glxinfo`? It's in the mesa-utils package, in [universe].

I know ati distributes their own opengl implementation with fglrx (they did when I used the driver back in 2007), and I'm wondering if maybe you're still using that, through some ubuntu driver-switching mishap. `glxinfo` would indicate if that was the case, and that'd tell us something done in ati's opengl implementation is what's causing all this to happen (and it would likely mean that switching back to mesa's opengl would solve the problem on your system).

Bill

Has anyone else tried updating to the Catalyst 10.11 driver? What are you experiences?

Thanks,

[Phillip Whelan (pwhelan)]

It has been proposed that we share the QGLContext. I have seen the code which is disabled for now. It is actually sharing a QGLWidget. This does not necessarily share the underlying QGLContext, as is explained here:

http://www.qtcentre.org/threads/24782-Whats-the-difference-in-sharing-a-QGLContext-and-sharing-a-QGLWidget

Just thought I'd jot that information down here.

[Phillip Whelan (pwhelan)]

This patch forces the QGL APIs to share the same OpenGL context, or so it should, according to the documentation.

Hopefully this solves the problem. Unfortunately I have no way of testing for myself, since I do not have an ATI card supported by the latest FGLRX driver.

[Gary Littlemore (gary-littlemore)]

Can someone explain what or how I do with the patch???

Thanks

[Bryce Harrington (bryce)]

Given that there's a mixxx patch, does anything need done for fglrx itself? If so, please run `apport-collect 656241` and elaborate if possible (patches welcomed).

[Phillip Whelan (pwhelan)]

In case you are not familiar with how to add patches to and compile source code, here is a copy of the program for Ubuntu than you can simply run to test this patch. You might have to go into the Properties of the file and change it's permissions to include permissions to Run or Execute the file.

If you know how to patch source code, we do have specific instructions on how to compile Mixxx on Ubuntu on our Wiki:

  http://mixxx.org/wiki/doku.php/compiling_on_linux

[Peter Havekes (peter-havekes)]

I've tried the binary. I've renamed /usr/bin/mixxx and replaced it with the mixxx Philip supplied. It complains about the database-version. I've removed ~/.mixxx/ but that didn't resolve it.

The error is:

[Peter Havekes (peter-havekes)]

@jus

Thanks for the hint. The problem was my setup was is /usr/share/mixxx, not /usr/local/share/mixxx

I've copied the files to /usr/local/share/mixxx/ and the patched version starts without problems, craches or waveform problems. The waveforms are displayed correctly, where previously my X crached.

Good work!

[Gary Littlemore (gary-littlemore)]

Sorry Guys, with me being a novice with Linux you've completely lost me, Could someone explain step by step what I need to do?

Any help is greatly appreciated.

Thanks

[Phillip Whelan (pwhelan)]

Follow these steps:

 * Right click the link to the 'mixxx' file I attached and do 'Save as..'. Save the file to your Desktop.
 * When the download is done look for mixxx on your Desktop, right click it and click on 'Properties'.
 * Go to the 'Permissions' tab and check 'Allow executing file as program'.

Tell me how that goes.

[Gary Littlemore (gary-littlemore)]

I've done that now Phillip, what next?

[Phillip Whelan (pwhelan)]

Can you double click it to see if it runs?

[Gary Littlemore (gary-littlemore)]

It ran, it opened Mixxx but then as usual Mixxx just went off after about 3 seconds.

Phillip have you seen Bill Good's posts where he thinks my problem maybe different then other peoples as I'm not using FGLRX? Are you able to help with is?

[jus (jus)]

@Gary
Open Terminal and drag the mixxx binary to a terminal window, then hit enter ( thus executing the binary). You`ll see the debug messages that give you a hint what went wrong.

[mrvica (malisha-serb)]

I want to report a most strange thing. I was one of the first to report this bug... Since then, I had almost given up on fixing the problem and used Mixxx either with my drivers uninstalled or waveforms deactivated. In the meantime, i had to reinstall Ubuntu 10.10, which I did. On the same hardware, with the same system, program version and the same video driver, now, everything works perfectly. I mean, it's a good thing :D But most peculiar...

In my opinion, your problem is related to this bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/557266

[phil(nice) (philgood052)]

Just a tip for all ubuntu users, if it is not mentioned somewere above: Before starting up mixxx, make sure you have compiz disabled. To do so, turning it off, or setting the visual effects to off, isn't enough cause compiz window manager would still run in the background.
Just hit Alt + F2 and type , "metacity --replace". This is the only way to disable compiz completely. If you need to revert back, Alt + F2 "compiz --replace". Quotations excluded ofcourse.

Ok, i deactivated the effects and now's ok. What about to make it working with all effects on? :-)

[phil(nice) (philgood052)]

knnwow, this is not possible as we speak. compiz is known to cause such problems for a long time. I know it is annoying having the procedure repeated every time you want to use some programs, but it's the only solution we have.
Perhaps someone could write a script for doing this automatically for every application inside a pre-defined group by the user.
And reverting back to compiz the same way.

[Bryce Harrington (bryce)]

[Dropping the -fglrx task, as since when I asked there's been no further indication that something needs changed in the video driver.]

[daniel (daniel309)]

Im also seeing this problem on the ati card (ATI Technologies Inc Mobility Radeon HD 3650) using fglrx. X just crashes and I have to hard reboot. I disabled the "Waveform display" in interface preferences and now I can safely run mixxx again.

When I started mixxx from the commandline, it did not crash my machine, but was showing a message that I have direct rendering disabled and that displaying the waveform might use a lot of cpu. And indeed, the waveform display was flickering heavily and not looking nice at all...

When I start mixxx using the menu icon, it crashes X until I disable the waveform display. Starting mixxx via icon actually starts "pasuspender mixxx". Does this help anyone?

[RJ Skerry-Ryan (rryan)]

Hi Bryce,

Sorry for not responding to you earlier. Basically we're at the point where we don't know what the problem is. I'm fairly sure it's not something wrong with Mixxx, but the way we are using the Qt OpenGL API's seems to elicit a hard system crash for users of FGLRX. The proposed patch has shown some promising results, but we aren't sure that it doesn't trigger the issue for everyone affected.

Whether this means it's an FGLRX issue, a Qt issue, or somewhere else in the stack -- I'm not sure. I'd definitely appreciate any advice you might have on trying to pin this down to a specific area. Unfortunately I (or any other Mixxx devs) can't seem to reproduce this on the little ATI hardware we have.

Thanks,
RJ

[Gabriel M. Beddingfield (gabrbedd)]

I built the 1.9-bzr branch (which includes the patch in comment 49), however it causes a crash for me (Qt 4.6.2 and 4.7.1). I think it's an issue with Qt, so I filed a bug with them:

    http://bugreports.qt.nokia.com/browse/QTBUG-17284

Meanwhile, the patch doesn't validate the QGLContext pointer, nor does it verify that QGLContext::create() was successful.

[Gabriel M. Beddingfield (gabrbedd)]

According to this thread[1], before constructing the QGLContext you need to create a QPaintDevice (e.g. QGLWidget) up-front and then use the marked-as-obsolete QGLContext constructor that takes a QPaintDevice.

[1] http://lists.trolltech.com/qt-interest/2008-08/thread00046-0.html

[Santeri Savonlahti (shanttu)]

Just wanted to report my status: 10.10, ATI 3470, fglrx enabled,
catalyst version OpenGL version string: 3.3.10428 Compatibility Profile Context.
/usr/lib/qt4/examples/opengl/textures/textures works fine.
All the best for getting this solved.

[Gabriel M. Beddingfield (gabrbedd)]

Please disregard comments #72 and #73. My problems are unrelated to this bug, and the code isn't necc. wrong. When the widget is constructed, it passes the context. However, QGLContext::create() is a NOP without a widget.

[Joey Dodson (ninjawailer)]

I previously had this problem. Two things seemed to fix it.

1) Purged the fglrx drivers and reinstalled the proprietary ATI drivers
2) Mixxx only starts if I disable compiz as recommended in post #65 (Thanks phil!!)

Now, I'm sure this isn't a long term solution for Mixxx and/or other programs that Mixxx may rely on causing this problem. However, this combination of fixes seems to work fine. Previously I could run Mixxx without waveform displays on, although now they are on and it starts fine (provided I first disable compiz after each restart).

I tried to automate turning off compiz by changing the Mixxx command to "metacity --replace && pasuspender mixxx", which I thought should run "metacity --replace" and then run Mixxx. It didn't exactly work. Perhaps it is different than using alt+f2, which runs it in tty2 (if I understand correctly). Should I have to specify that the first command run in tty2 somehow? Anyways, Mixxx works on my system provided the above two conditions are met.
