Description John Elliott Martin 2005-04-25 11:50:54 UTC

Distribution: 
Suse Linux 9.2 
 
Hardware Environment: 
Averatec 3300 laptop. Intel 855GM chipset. 
 
Software Environment:

Problem Description: 
Standby goes down fine, but when resuming there is no video. I have tried this 
from the console and from X and the same thing happens. Also, I have tried 
logging in 'blind' after resuming, but still nothing. I cannot SSH into the 
computer after the resume either. 
 
Steps to reproduce: 
Get an Averatec 3300 laptop. Put it in standby mode from linux. Resume the PC.

Any luck with:
1. BIOS upgrade.
2. X upgrade, or at least X video driver
3. workarounds in Documentation/power/video.txt?

Please reopen this bug if:
- it is still present in kernel 2.6.16-rc2 and
- you can answer Len's questions.

I have tried all your suggestions. Let me answer them here for you.   
   
First off, there are no available BIOS upgrades for my laptop.  I tried a new  
video driver for this board, and had the same results. I tried all the  
workarounds in Documentation/power/video.txt, and still had the same results.  
  
I just downloaded, compiled and booted into 2.6.16rc2 and when I come back 
from S3 with that kernel I can drive, but I can't see. I booted to runlevel 3 
and tried init 5 from the console after resuming and got nothing on the 
display either. ctrl alt 1 and init 6 rebooted though, so it's just the 
display. 
 
If there is anything I can do to help, or any data I can provide, let me know 
as I have a good test environment set up now.

Video restore on resume from S3 is a BIOS or video driver issue,
not an ACPI issue.  Moving to drivers/video.
