Description Ilya 2006-02-06 03:16:40 UTC 
Description of problem:
CMOS clock/date change causes ATI display go blank on nF4 Ultra

Version-Release number of selected component (if applicable):
kernel 2.6.14-1.1656_FC4, x86_64

How reproducible:
Change time/date in control panel, click "Apply".

Actual results:
Depending on change, display goes blank temporarily or permanently.

Additional info:
Discovered on LanParty UT nF4 Ultra-D, AMD 64
Blind log-off sometimes can restore display.
Also suspect that time-server synchronization causes same problem occasionally

Screen also can go blank after reboot when the above symptoms happen. 
Restoring CMOS settings (LanPart has CMOS recall feature) fixes that.
Comment 3 Dave Jones 2006-02-19 05:47:58 UTC 
if the time adjusts by enough that the screenblanker interval has passed, that
would explain why the screen goes blank.   Why it stays blank I've no idea.

What graphics driver is in use here?

Are there any messages in dmesg after it happens?

Closing due to lack of response.
