I am running Sid with KDE 4.x for a while, coming from Mandriva 2009.1. In Mandriva, I was able to suspend/hibernate easily. But in Debian Sid, I cannot suspend (nor hibernate but that's another issue). When I click on K Menu > Leave > Suspend to Ram or the Sleep button from the Battery Monitor, the system goes to sleep (hdd spin down, screen blanks, etc) as expected. But when I hit the Power button to resume, I can't get X working. I can hear the hdd working, and the screen seems a little more bright but there is no KDE. I tried to switch virtual terminals (Ctrl+Alt+FX) but nothing happens. This bug report might be related to #561877, although the latter is about another Sony laptop model and, what is more, I have already tried the workaround described by Adriano (disable s3_bios, enable s3_mode) with no success. I also tried some other pm-suspend options.
I am also attaching pm-suspend.log. I had issued PM_DEBUG=true pm-suspend, system suspended but not resumed. I had to press and hold Power button to force a poweroff.
FYI, in case lshal might help... root@vaio:/home/dimitris# lshal | grep hardware system.hardware.primary_video.product = 38227 (0x9553) (int) system.hardware.primary_video.vendor = 4098 (0x1002) (int) system.hardware.product = 'VGN-NW21SF_T' (string) system.hardware.serial = '27505265-5003089' (string) system.hardware.uuid = 'E9678920-DA59-11DE-8980-0024BE848791' (string) system.hardware.vendor = 'Sony Corporation' (string) system.hardware.version = 'C6037FK7' (string) laptop_panel.brightness_in_hardware = true (bool) info.product = 'HDA Intel ALSA hardware specific Device' (string) info.product = 'HDA ATI HDMI ALSA hardware specific Device' (string)
Testing some scenarios. First, I used this one PM_DEBUG=true pm-suspend --quirk-dpms-suspend No success. Screen stayed blank after resume. Attached the /var/log/pm-suspend.log for this try.
Also tested this configurarion - again with no success (system hanged after resume with no screen activity): PM_DEBUG=true pm-suspend --quirk-vbestate-restore --quirk-vbemode-restore --quirk-vbe-post Attached the new pm-suspend.log.
