Description Trond Danielsen 2006-05-21 06:43:24 EDT
Description of problem: Resume from suspend to ram fail on Asus S5A (also known as Asus S5000). The graphics card is an intel 915. The machine resumes, and I can log into it remotely with ssh, but the screen remains blank and it doesn't respond to input from the keyboard, only the special keys that acpi handles works (I can press the power button to turn it of, but I can't kill X with ctrl-alt-bs or reboot with ctrl-alt-del) Version-Release number of selected component (if applicable): kernel-2.6.16-1.2111_FC5 pm-utils-0.15-1 How reproducible: Every time. Steps to Reproduce: 1. Select suspend from the gnome menu 2. Wait until the machine suspend. 3. Resume by pressing any key. Actual results: The screen remains blank, but I can still log into it with ssh. Expected results: The machine should resume from where it was before suspend... Additional info: I have tried to add acpi_sleep=s3_bios kernel parameter, but that didn't solve it. The complete spec for the machine can be found here: http://www.asus.com/products4.aspx?modelmenu=2&model=500&l1=5&l2=75&l3=127

I would suggest trying the 915resolution tool after resuming, or (failing that) vbetool.
Comment 3 Phil Knirsch 2007-01-23 11:01:58 EST
Have you tried this with newer version of pm-utils? There are quite a few changes in the FC6 version of it that might fix the problem you're describing. Thanks, Read ya, Phil

I just tried it again. This time it actually resumed, after switching from X to console and back again to bring the display back on. However, another problem occured, which forced me to reboot. I attached the output from dmesg and /var/log/messages

After upgrading to the latest kernel (2.6.19), suspend and resume works just fine, except that I have to a text console, back to X and then manually adjust the brightness of the display to turn the backlight back on.

FC5 is now end of life, so sadly this bug won't be fixed in this release. Is this bug still presend in FC6 or F7?
Comment 9 Trond Danielsen 2007-09-04 08:37:04 EDT
As mentioned in comment #7, suspend now work ok on my laptop. I therefore suggest that this bug should be closed.
Comment 10 Till Maas 2007-09-04 08:59:09 EDT
You should not need to manually turn the backlight on, so I keep this open, maybe this can be fixed, too.
Comment 11 Nigel Cunningham 2007-09-10 18:49:51 EDT
I see above you tried acpi_sleep=s3_bios without success. How about acpi_sleep=s3_mode or acpi_sleep=s3_bios,s3_mode. If either of these later two work, you could submit a quirk for your laptop to Richard Hughes, and it would then just work with a future pmutils version.
Comment 12 Trond Danielsen 2007-09-15 16:28:00 EDT
My laptop now runs F-7, and the backlight issue have been fixed in this release. Whether the problem has been solved by a new kernel or an updated pmutils package, I do not know.
