It really is not enabled by default: ferna...@vostro:~$ cat /etc/modprobe.d/i915-kms.conf options i915 modeset=1 > > Fernando, do you still have this issue with 2.6.34 (from experimental)? > If it's fixed upstream it might be possible to backport the fix to > squeeze's kernel. I just installed 2.6.34 from experimental (added experimental to sources.list and apt-get installed -t experimental linux-image-2.6.34-1-amd64) and reverted my changes to /etc/defaults/grub and re-ran update-grub to make sure. So I'm using modeset=1 (it's in 915-kms.conf) and powersave is unchanged, it should be enabled by default: ferna...@vostro:~$ uname -a Linux vostro 2.6.34-1-amd64 #1 SMP Wed May 19 19:06:22 UTC 2010 x86_64 GNU/Linux ferna...@vostro:~$ dpkg -l | grep linux-image ii linux-image-2.6-amd64 2.6.32+27 Linux 2.6 for 64-bit PCs (meta-package) ii linux-image-2.6.32-5-amd64 2.6.32-13 Linux 2.6.32 for 64-bit PCs ii linux-image-2.6.34-1-amd64 2.6.34-1~experimental.1 Linux 2.6.34 for 64-bit PCs ferna...@vostro:~$ The screen flickered 4 times during the time I was composing this e-mail, so I guess it's not fixed upstream yet.
