[Filippo neri <fneri23@xxxxxxxxxxx>]

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.

As far as I am concerned, this is a kernel bug introduced between 2.6.32-19  and 2.6.32-21,
but unfortunately, still present in 2.6.32-22. 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.
