Just as an aside, my issue with the 2.6.32 kernels turns out to be a |
| 11 |
bios bug: the bios reports the lid to my netbook is closed even when |
| 12 |
it is open (cat /proc/acpi/button/lid/LID0/state shows 'closed'). Now |
| 13 |
starting kernel 2.6.32 apparently the KMS was 'fixed' to trust the |
| 14 |
bios reporting, hence it does not think *any* computer display is |
| 15 |
attached to the computer. |
| 16 |
|
| 17 |
This leads to a kernel error on boot and a blank screen. |

Anyway, Pablo (whoever you are: thanks!), a gentoo user, commented on |
| 20 |
a Ubuntu bug report |
| 21 |
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/515246/comments/55 |
| 22 |
and provided the RTFM response: apparently we can override the bios by |
| 23 |
passing a suitable boot parameter to explicitly enable the LCD display |
| 24 |
on the laptop. |
| 25 |
|
| 26 |
With this now I'll be able to upgrade to a newer version of the kernel |
| 27 |
and test out the new intel X drivers. |
