Description Peter Cordes 2008-09-28 17:48:06 UTC

BTW, I was unable to mark this bug as version: 7.2, because it's not in the list yet.

The copypixrate demo inside Xephyr (no DRI: swrast dri not installed) fails with:

...
GL_RENDERER: Software Rasterizer
Draw Buffer: Front
X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  73 (X_GetImage)
  Serial number of failed request:  11939
  Current serial number in output stream:  11939

 Other mesa tests do work inside Xephyr.

I'm on AMD64 Ubuntu pre-Intrepid.
X 1.5.1
Xephyr 1.5.1
libgl1-mesa-dri          7.2-1ubuntu1
no libgl1-mesa-swx11 (aka ...-swrast)

  I compiled the tests from the latest git version, but I'm using Ubuntu's packages for X and mesa.

 If this isn't reproducible, I can collect more details.

swrast_dri.so is in libgl1-mesa-dri...

 err, yeah.  so maybe mesa was using it for software rendering inside Xephyr.

  I'm trying to track down some assert() failures with shaders, e.g. in vegastrike (g965 and software), and a crash in Spring on g965 but not with software mesa rendering in Xephyr.  I'll report these as separate bugs, of course.
