Hi guys, this is really strange. On my system (Z31/WN) with Karmic,sony-laptop-zseries-0.9np1 and Grub2, I have used only INTEL graphics so far. After deciding to test the instructions on Raphael's blog (very nice, thanks for all the efforts!) I found some bits of information which may be helpful here.
I am using the latest karmic 2.6.31.11 kernel right now because today's 2.6.31.12 update does not boot. My older kernel still contains Norberts 0.9np1 module. First, on my systems the Speed/Stamina LEDs stopped working too, initially. This was after applying all the changes mentioned in Raphael's instruction. After some backtracking I was able to fix the Grub2 problem by tweaking /etc/default/grub like this: (...) GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor" GRUB_CMDLINE_LINUX=acpi_osi='"!Windows 2006"' (...) The update-grub command successfully generates the /boot/grub/grub.cfg file which contains menu entries that have config lines such as this one: linux /boot/vmlinuz-2.6.31-11-generic root=UUID=e540f235-d66b-4a46-839d-4fd034fdec67 ro acpi_osi="!Windows 2006" quiet splash acpi_backlight=vendor The system boot okay. But here comes the kicker: The speed/stamina LEDs still stay off unless I remove the /etc/modprobe.d/sony-laptop.conf file. Without this file (and the module parameter it contains), the module loads okay, apparently. /var/log/messages contains: Oct 8 00:36:11 archangel kernel: [ 148.959478] sony-laptop: Sony Programmable IO Control Driver v0.9np1. Oct 8 00:36:11 archangel kernel: [ 148.959528] sony-laptop: detected Type3 model With the current state of the system, the Intel graphics works. But the switch-x-to script does not: syslog.1:Oct 8 00:03:00 archangel init: switch-x-to main process ended, respawning syslog.1:Oct 8 00:03:00 archangel init: switch-x-to main process ended, respawning syslog.1:Oct 8 00:03:00 archangel init: switch-x-to main process ended, respawning syslog.1:Oct 8 00:03:00 archangel init: switch-x-to main process ended, respawning syslog.1:Oct 8 00:03:00 archangel init: switch-x-to main process ended, respawning syslog.1:Oct 8 00:03:00 archangel init: switch-x-to main process ended, respawning syslog.1:Oct 8 00:03:00 archangel init: switch-x-to main process ended, respawning syslog.1:Oct 8 00:03:00 archangel init: switch-x-to main process ended, respawning syslog.1:Oct 8 00:03:00 archangel init: switch-x-to main process ended, respawning syslog.1:Oct 8 00:03:00 archangel init: switch-x-to respawning too fast, stopped This happens when booting and is probably caused by the strange state of the system.
