LCD & backlight restore problem. Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hi, I tried suspend on ram on my VAio FX 801 & kernel 2.5.69, with echo "3" > /proc/acpi/sleep That works great, system goes to sleep and red light blinking. But When i try to resume, i can see the display coming back for a few milliseconds, and then LCD goes black & backlight turns off. I'm sure the kernel is correctly restored because i run commands like locate -u or reboot in "blind mode", so my problem is the video mode restoring. if i try acpi_sleep=s3_bios, i get blacklight on & LCD all white. Do you have ideas on what can cause this strange behaviour. any comments welcome NB: my vaio pass blacklist test at boot up thanks. Olivier Fauchon
