standby and hibernation don't work

I please need some help in brigantia:

standby does work but wake up from standby does not. apparently, my screen just doesn't wake up. Because, after re-start, the hdd starts up, but the screen stays black. when I press ALT-CRTL-DEL, and ENTER, I can shut the computer down.

hibernation does not work at all. half way down hibernating, the computer crashes.

my system: thinkpad T40, 1.5GHz pentium M, 1Gb RAM.

Thank you, anatom

leny2010, thank you very much!

I have fixed the suspend issue on my system by
1. adding nomodeset to GRUB-CMDLINE-LINUX-DEFAULT in /etc/default/grub
2. and adding the rfkill block/unblock wifi commands to the NetworkManager-file in /usr/lib/pm-utils/sleep.d/

both as described by lembas in the linked thread.

I forgot to test hibernation mode, just a minute ...

pity! hibernation does not always work properly! sometimes it does, sometimes it does not.

are there quirks for hibernation?

many thanks for the link, again.

so on my machine, it was the 'nomodeset' value and the wifi that made the difference with suspending. nothing about the video card. as it seems to me.

what does 'nomodeset' do (to the kernel?) ?

was the category the right one? support request? or could I say it was a bug?

thanks, anatom

Great! In the end, I added an /etc/pm/config.d/quirkfile with ADD_PARAMETERS=--quirk-dpms-suspend (which is "my quirk"), as lembas described, and now even hibernation works! :-)

Many thanks for the support!

Thanks for your praise.

As to the category I was only going by the plain English meaning. This was likely not a bug in Trisquel, but you needed support to configure it to work well with your hardware.

Marking as fixed since it seems to be solved.

Glad to hear my findings were useful! I don't understand too much about kernel mode setting but here's something on the subject:
