Kernel was 2.6.4-rc1. Here is some feedback for you: It finds 4 vido devices, and I have the following directories under /proc/acpi/video/VID: CRD0 DVI0 LCD0 TV0 cat /proc/acpi/video/VID/info Switching heads: yes Video ROM: no Device to be POSTed on boot: no cat of POST and POST_info gives . I am still able to switch between CRT and LCD with the Fn+F7 as usual, but I cannot switch with the method described in README file from your patch. However the information from CRT0/state file is correct: 0x1f when active and connected 0x0f when active and disconnected from crt 0x1d when disabled and connected to CRT 0x0d when disabled and no CRT attached To verify these values, I used Fn+F7 to switch between heads. cat /brightness If you need more information/logs/testing please let me know. I have access to other IBM thinkpad models for testing. ------------------------------------------------------- SF.Net is sponsored by: Speed Start Your Linux Apps Now.
