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-X, which is subscribed to xserver-xorg-video-ati in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
