We have exactly the same kind of ATI board ("01:00.0 VGA compatible controller: ATI Technologies Inc RV350 AS [Radeon 9550]") which we can quite reliably and quickly crash in Jaunty by just taking "Preferences / Screensaver" and with "Preview" previewing some 3D-intensive screensavers; "SkyRocket" seems one of the quickest to kill the machine and turn off DVI signal to the LCD monitor.
We will experiment with 'Option "NoAccel" / "DRI" "false" / "RenderAccel"' and with 'Disable "glx"' but I'm suspecting that disabling anything which prevents screensavers from using OpenGL with direct rendering is going to help... -- Jaunty locks up https://bugs.launchpad.net/bugs/374831 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
