A23, Radeon 7500, ps2-type keyb.), and these are the symptoms I have encountered: 1. The display stays black after resume (text). If suspending/resuming from X, some "scary" visual effects resembling "LCD hypothermia" appears, followed by a dark (but backlit) screen. Typing commands on the keyboard gives no response. 2. echo 3 > /proc/acpi/sleep; sleep 10; reboot; does run, indicating that at least one process resumes correctly. 3. A key logger (Linux Key Logger; userspace) stops logging after resume (though /var/log/messages continues to write (no errors)), indicating that it has died somehow (although ...; ps -A > dump; indicates that it hasn't). What are the likely causes of this problem? Is it a timer-, interrupt-, keyb.-, or video-problem or a pure ACPI problem? Where should I start debugging? Any help og advice is greatly appreciated. -andreas ------------------------------------------------------- This SF.net email is sponsored by: SF.net Giveback Program.
