Could you advice me with steps for troubleshooting this?
This is very often related to graphics driver problems and the way they
(don't) work well with X.
For someone to help you out you'll need to let everyone know:
1. What graphics chipset does your laptop have?
2. What drivers are you using (the ones that came with SL6.2, homespun or
proprietary)
3. What desktop environment are you using?
4. Do you have graphic accelerated screensavers running as part of the
wait-idle-suspend cycle?
5. Do you have screen locking enabled from blank screen or suspend?
6. Is you computer suspending or hibernating?
With that information someone will probably stand a decent chance of helping
you out -- even if its just to say "hopeless; turn off suspension/sleep".
To begin with, thank you for your answer.
Well, Acer Aspire 3003LMi has SiS M760GX graphics chipset (which I had
not been able to get 3D-acceleration from from any distribution). For
SiS M760GX, I use the drivers that came with SL6.2. I use the default
desktop for SL6.2 (GNOME). The problem with suspend-resume is there,
both with screen locking or not. Hibernation worked ok last time I
checked, the problem is with suspend (to RAM) and resume.
Starting with that, the short answer is:
Disable suspension and rely on hibernation.
The long answer begins with:
Try the SiS Xorg drivers from here:
( http://w3.sis.com/download/agreement.php?url=/download/ )
See if the problem persists. If it does, you can start poking around
your xorg.conf and enabled X features to hunt for a different way (also,
you might want to blacklist the default drivers in this case).
(Unfortunately I know very little about SiS at all. I've had mixed
results with AMD suspension, so I disable it by default and use
hibernation directly -- but AMD graphics work awesome with their
drivers, so its worth it.)
