Description Rafał Lorek 2009-06-15 10:22:29 UTC 
When I enable KMS by this command:
modprobe i915 modeset=1 

I get black screen. Only way to repair this is restart machine (Ctrl-alt-del works)

I've never managed to get KMS working.

distribution:

Your last add seems to say that this is fixed?  Can we close this?
Comment 4 Rafał Lorek 2009-06-17 00:07:48 UTC 
Yes, please close it.
I have been trying to enable KMS, by modprobe (modprobe i915 modeset = 1) command,
but I forgot to check if kernel parameters (i915.modeset=1) works.
