This same bug affects two Dell computers here, both with Intel graphics (865G and 945G), so I think that [not only] the driver is guilty here, but the X server too. Both computers are running Intrepid, one was updated from Hardy and the other one is a new install. The bug is usually fired after a weekend of inactivity.
I'm attaching the log of the latest hang in one of those computers, in case it may help. The fatal "infinite loop" message appears first at line 673350, before that the X server insisted on probing the monitor every half a minute or so (I think). ** Attachment added: "X.org log" http://launchpadlibrarian.net/19897700/Xorg.0.log.old.gz -- [x700] server looping and system hang (DRILock+0xfa) https://bugs.launchpad.net/bugs/295904 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
