Description Maciej Paszta 2004-11-23 11:25:59 UTC

Hardware Environment:
Hewlett Packard OmniBook6000 laptop with BIOS rev. 1.83

Software Environment:
ACPI subsystem revision 20040326

Problem Description:
When I do echo 3 > /proc/acpi/sleep. My laptop turns goes into sleep-mode
without problems. But when I try to wake it up display remains blank. I've tried
to add acpi_sleep=s3_bios and after this, display wakes up with green lines on
it, and the only way to get rid of them is to reboot.

Steps to reproduce:
echo 3> /proc/acpi/sleep

Could you try suspend/resume cycle from X window?
Comment 7 Maciej Paszta 2004-12-15 13:25:02 UTC
OK I've tried this (also on 2.6.10 kernel) and after resuming XWindow system
appears for a short period of time (about one second), and then again display
goes black and green and purple dots appear.

Please try the workaround in bug #3670
Comment 9 Maciej Paszta 2005-01-04 07:17:46 UTC
Unfortuantely, it doesn't work. I've tried it with 2.6.10 but with no effect. I
used the script included in README but afret resuming I hear only loud beep and
display remains black (without s3_bios) or has some green dots (with s3_bios).
Comment 10 Len Brown 2006-08-09 20:42:55 UTC
Video restore upon S3 resume is a BIOS or video driver issue,
not an ACPI issue.  Moving to drivers/video.
