I get the same problem with an Acer Aspire One 751h running full screen resolution (1366x768) with 2.6.28-13, but not with 2.6.28-14 !
The poulsbo GMA500 Xorg driver (psb) is provided by "ubuntu-mobile/ppa" : https://edge.launchpad.net/~ubuntu-mobile/+archive/ppa, and configured by apt with de "poulsbo-driver-2d" package. The "poulsbo-driver-3d" package has the same problem. I provide the X log in attachment. Do you need something else ? ** Attachment added: "Failsafe X log" http://launchpadlibrarian.net/29704093/failsafeX-backup-090729234526.tar -- 2.6.28-14 kills PSB driver on Dell Mini 10 https://bugs.launchpad.net/bugs/406651 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
