Bug#592415: Invisible mouse update
The latest kernel from experimental (2.6.35-1~experimental.2) didn't
solved the problem.
I've done some research and i can confirm that this bug is related to
855 intel chipset, and it is quite common.
These bugs from Ubuntu and Arch contains useful informations:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/614176
http://bugs.archlinux.org/task/20373
It's not clear where the bug is: kernel or xserver-xorg-video-intel?
On bugzilla.kernel.org i haven't apparently found no bugs related to
this, but i have to admit that i feel really uncomfortable with their BTS.
These are the test i've done so far:
- since i'm running xserver-xorg-video-intel from experimental, i've
tried to downgrade to the one in Sid: no change.
- upgraded mesa to experimental: no change.
- 486 kernel: no change.
- 2.6.35-rc6: mouse works.
- 2.6.34: mouse works.
- 2.6.32 (Squeeze kernel): mouse works.
So between rc6 and 2.6.35 something in the kernel has clearly changed.
And even if the Intel X driver could have some responsability, i've
verified that both the 2:2.9.1-4 from Sid and the latest 2:2.12.0-1 from
experimental works well with all the kernel except
2.6.35-1~experimental.1 and 2.6.35-1~experimental.2.
Cesare.
