Resume from suspend in Fedora 8 give blank screen

cdhgee · 11-10-2007, 11:30 AM

I've just installed Fedora 8 on my Dell Inspiron 1420n laptop, and I'm trying to get suspend (to memory) working. Hibernate already works fine, out of the box. Suspend works fine, but when attempting to resume, the display remains blank. The backlight usually flashes briefly, but goes off again, so I think it's powering on OK, but X never resumes. However, if I press Ctrl-Alt-Backspace, X restarts and I can log in again.

I've tried playing with the various quirks on the HAL quirks website, but none of them seem to help. Two quirks are enabled by the quirks config files for my machine:

Code:

lshal | grep quirk
  power_management.quirk.vbe_post = true  (bool)
  power_management.quirk.vbestate_restore = true  (bool)

Any suggestions?

Regards
David

I have exactly the same problem. I thought suspend2 (aka tuxonice) would solve the problem, but it was not the case. I checked hundreds of websites and forums about the topic, but could find no solution that works for me.

I'm having a similar problem on a desktop system. Actually, I'm not able to disable the sleep/hibernate modes. Using the screensaver menu, I've disabled the computer and display in the Power Management sub-screen, but it still goes to sleep! No quirks are enabled.
