This seems to be triggered when the overall geometry of the combined frambuffer is >2048 pixels wide, leading to a frambuffer too wide error and unity to abort.

Andy, can you try this with Natty on the same machine and see if this still happens?

Mirco Müller (macslow) wrote :

Ups... sorry, never mind Andy, just saw that Natty is the version you tried this on.

Mirco Müller (macslow) wrote :

Just for the record, can you attach the output of "glxinfo -l | grep GL_MAX_TEXTURE_SIZE" here? It's probably that the max. texture-size is 2048 on your intel GPU. For such cases we'll need a fallback code-path to use an approach to used tiled-buffers.

It is more directly an issue of the library underlying unity. I've added it to the affected projects.

It affects me too. And running "glxinfo -l | grep GL_MAX_TEXTURE_SIZE", I got:
    GL_MAX_TEXTURE_SIZE = 2048
As you suspected.

Quick note to say that cloning the display on the external monitor doesn't trigger the issue, since i've been able to do a presentation on Friday and was running Unity.

As you suspected I do indeed have a 2048 pixel texture size:

  $ glxinfo -l | grep GL_MAX_TEXTURE_SIZE
      GL_MAX_TEXTURE_SIZE = 2048

I also will note it is possible to put the monitors above each other which keeps both under x and y under the 2k limit without issues.

Andy Whitcroft (apw) wrote :

I will further note that this machine has socket insertion detection, and the default location is non-mirrored and on the right of the main screen. This means that as soon as you insert any monitor wider than 1024 pixels (the norm these days) either unity or compiz explodes. No user action is required.

Panel no longer stretches the width of both monitors, it is only the width of the primary monitor. Dash fullscreen does the same, so we're safe from this bug now.

Currently running wth Unity 2.8.4-0ubuntu1, the same or very similar symptoms are still present. Plugging an external 1024x768 monitor into my Atom netbook leaks to unity core dumping, on restart it spits out errors about the size of screen being to large:

    GLRenderbuffer::GLRenderbuffer() ERROR: Size too big width=2304height=1024

@Alex -- can you at least explain why you have moved this bug fix released again. As the original reporter I have reopened this bug as still present even with the supposedly fixed packages. That tends to indicated the bug is not in fact fixed?

It seems to be an issue between compiz and the driver, not the one fixed in the branch we had.

I have this issue for a config with laptop + external monitor (1366x768 + 1280x1024). Asus i3 2.53 GHz using the integrated GMA HD video card.

My GL_MAX_TEXTURE_SIZE is 4096:

glxinfo -l | grep GL_MAX_TEXTURE_SIZE
    GL_MAX_TEXTURE_SIZE = 4096
