My situation: System: Thinkpad X40 Intel(R) Pentium(R) M processor 1.40GHz Memory: 1.5 GiB, Intel 855GM Chipset Ubuntu Release 10.04(lucid) installed from the beta2 CD and updated to the latest packages (including lucid-proposed and lucid-backports.) I have installed the following kernels: 2.6.32-19-generic 2.6.32-21-generic 2.6.32-22-generic 2.6.34-020634rc5-generic (I upgraded to 2.6.32-22-generic today. ) Results (VERY repeatable!) 2.6.32-19-generic → OK 2.6.32-21-generic → Black screen 2.6.32-22-generic → Black screen 2.6.34-020634rc5-generic → OK By OK I mean everything seems to work fine, and I can use the “Normal” Visual Effects setting.

I have the choice of using 2.6.32-19, but I will use 2.6.34-020634rc5 for the next few weeks to see if any problem arises. -- MASTER: [i855] GPU lockup (apport-crash) https://bugs.launchpad.net/bugs/541511 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
