Red Hat Bugzilla – Bug 73524
When using battery screen doesn't restore from blanking ATI Radeon Mobility M7
Last modified: 2007-04-18 12:46:22 EDT
Description of Problem:
This is not a Suspend issue (that works fine). This is a simple screen
When I'm on battery power if the screen blanks and I move the
mouse or touch a key to bring it back, I get an orgy of colors and
static on the screen.
The machine itself is not hung up. A CTL-ALT-F1 doesn't change the
screen all that much, still messed up. I can "blindly" login though and
do an 'init 6' to reboot.
Other aspects of the video on battery power work fine including
suspend/resume. I bought this laptop 4 weeks ago (right after Limbo2
came out). I've seen this behavior the whole time. RHL 7.3 won't install
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot to runlevel 5
2. Wait until the screen blanks
3. Move the mouse, observe the chaos.

I commented out the "dpms" option in my monitor section (see below). No change
VendorName "Monitor Vendor"
ModelName "Monitor Model"
# Option "dpms"
Use xdpyinfo to confirm DPMS is disabled at runtime. Other applications
like GNOME control panel, xscreensaver, xset can enable DPMS regardless
of the config file settings.
Also attach your config file and X server log file as individual attachments
using the link below.
