GLX failure: couldn't get an RGB, Double-buffered visual

[John Moser]

This happens with the via driver:

bluefox@icebox:~$ glxgears
__driCreateNewScreen_20050727 - succeeded
libGL warning: 3D driver claims to not support visual 0x22
libGL warning: 3D driver claims to not support visual 0x23

libGL warning: 3D driver claims to not support visual 0x2c
libGL warning: 3D driver claims to not support visual 0x2d
Error: couldn't get an RGB, Double-buffered visual

The vesa driver reports other libGL warnings I believe, but the same error occurs.

Here is a clip of Xorg.0.log showing DRI is enabled:

This bug is related to (and possibly a duplicate of):
  #29493

This bug produces symptoms similar to similar but is fundamentally different from:
  #36314 (DRI is disabled in Xorg.0.log)

This bug may affect other open source and binary Xorg drivers.

This Xorg.conf is fresh, but the bug still happens. I'm attaching it and its matching Xorg.0.log.

[John Moser (nigelenki)]

Xorg.0.log from server running with above configuration. Also relavent interesting information from a terminal:

It appears this may be (yet another) 64-bit bug. According to the man page, the via driver is not entirely 64-bit clean, and 3D accel is busted on 64-bit.

[Rodrigo Novo (rodarvus)]

John, "man via" on an Edgy system will show the current man page for the via driver - and on this current man page, I see on reference of 64-bits related bugs on the driver.

Anyhow, I've uploaded a new version of this driver today, and wold be immensely grateful if someone could try to reproduce this error with it, and report here the result (also feel free to close the bug, if the error is gone)

[Martin Schaaf (mascha)]

I have this bug with dapper and a bug fix release for dapper would be fine.

[Timo Aaltonen (tjaalton)]

John, Martin: do you get this error with edgy/feisty?

[Martin Schaaf (mascha)]

I can't test for now, but I plan an update on the end of this month.

[Timo Aaltonen (tjaalton)]

you can try with the livecd, I think.. no need to install.

[Martin Schaaf (mascha)]

This isn't possible if try without the "safe graphics" I get a black screen. (Ubuntu 6.10 livecd)

[Martin Schaaf (mascha)]

I do not get it with the feisty beta live cd.

Thank you for reporting this bug to Ubuntu. The version of Ubuntu referenced in this issue has reached end of life, and the issue is fixed in newer versions of Ubuntu. Therefore, I am closing the Dapper task.
