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):
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
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.
