Red Hat Bugzilla – Bug 109297
Installation issue with DPMS console blanking...
Last modified: 2007-11-30 17:10:33 EST
Description of problem: During installation, if the machine is left unattended in between CD's, and the console blanking (DPMS) activates, it is not possible to reactivate the screen. Version-Release number of selected component (if applicable): How reproducible: 100% Steps to Reproduce: 1. Install... don't touch the keyboard while installing from CD 1. 2. Wait for the screen to blank. 3. Pressing any key (including ctrl-alt-f[1...12]) doesn't wake the monitor. Actual results: Expected results: Additional info: Graphics card: Nvidia TNT2/32mb.
apm=off,acpi=off at boot solves this problem... this should probably be the default during an install. Note: I've recreated this issue on several different platforms. Worst-case: on a laptop running on batteries... screen blanks regardless of activity, closing and opening the lid wakes screen, but disconnects kbd/mouse... putting machine to "sleep" (power button) then waking reactivates kbd/mouse... but disconnects USB CD/ROM. It gets pretty ugly.
