Bug Description
Hi,
I tried to run Ubuntu 10.04 amd64 on my new Lenovo U160.
Inside the Lenovo U160 works a Intel Core i7 620UM (arrandale) with integratet graphics.
The error looks like this: https:/
I know an other Lenovo U160 with Intel core i5 520UM which has the same problem.
I only can use it with the kernel boot parameter i915.modeset=0 in vesa-mode.
I am at my wit's end.
thx for your help
Sascha

I have here a Sony Vaio Z laptop. It's a fairly new model with switchable graphics: it has both a GeForce and an Intel integrated graphics chipset.
I can configure the BIOS so I can enable only one card during any given boot, using the selector switch on the laptop. At this point it ought to be just like dealing with a single adapter for the OS, so we should be able to cope with driving either adapter using nouveau or intel (respectively). In fact, neither work. Here's the report for the intel adapter.
As soon as i915 gets loaded with KMS enabled, the screen goes blank (with the backlight on). If I load i915 without KMS, it succeeds, but obviously this is no use for actually running X now the UMS support is gone from the X driver.
I will attach relevant sections from /var/log/messages , and the lspci -nn output. Xorg.0.log doesn't seem useful in this case as the failure is earlier.
Chip is: 00:02.0 VGA compatible controller [0300]: Intel Corporation Core Processor Integrated Graphics Controller [8086:0046] (rev 02)
