A perusal of the linux code seemed to indicate that VESA blanking would be attempted if APM blanking failed, but perhaps I wasn't reading as carefully as I should have been? --Scott Vesa unblanking gets called regardless because the VESA routines are used to get the right stuff back to the right console. I tried changing to only get called if APM unblank failed, and got some weird screens :) I also fiddeld with the time of the console blank interval and the BIOS blank time to figure out what was blanking the X screen but not turning off the back light. It is clearly the VESA stuff, indicating that APM is failing, but I do not get an error msg. with Ox0100 setting. If X is not running at all, APM works great, but if X is running and I'm on a non X vc, the backlight goes off, but comes back on after a few minutes. Have not tried upgrading X yet. (BIG DOWNLOAD). I don't do windows anymore, but when I did it worked fine. I do think that some of the problem may be in the vesa code rather than the apm_bios.c code. Guess it time to bite the bullet on X. -- Garst - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.rutgers.edu | ||||||||||||
