    black screen on wake up for acer 5535

    Hello Ubuntu community.
    I have an acer aspire 5535. when it goes into suspension and after i try to wake up , it doesn't seem to show signs of life ( black screen)..
    I did a search and found many other cases similar to mine, but none of the solutions / workarounds are compatible with my problem
    (I tried to kill the xserver, change the screen mode with FN + F4, type the user password and press enter ..but nothing... the problem is that as soon as i press a button to wake up, it seems to read the harddisk for 2 seconds and then it doesn't responds to anything except forced poweroff, pressing power button for 3 secs)

    Re: black screen on wake up for acer 5535

    I've been having the same problem for a while. That also happens on another Ubuntu-based distro. I read extensively the forum, looking for clues of what might have been happening, but I haven't found anything.

    Some people suggested alternative methods such as 'hibernate' and 'uswsusp', none of them worked. Some changes on grub didn't do a thing either.
    All I get after waking up is a blank screen, I can't toggle function keys like Caps Lock and if I press Fn + F4 it just gives a loud beep and doesn't do a thing.

    I'd be happy to help with logs, but I think enough logs have been spread around the forum. Something I heard might work was updating the kernel to 2.6.36, but I'm not confident I can do such thing without ****ing up a few times first.

    Oh, and I use the same laptop. Acer Aspire 5535. I guess specifically it's 5535-50, since it's the model without Bluetooth. It probably makes no difference, though.

    Re: black screen on wake up for acer 5535

    Hey, I'm back on ubuntu 10.04 I still have this problem with suspend/hibernate on this acer I was wondering if it is possible to port something from fedora and openSuse to make this suspend/hibernate work ?

    As this guy says that something works, something does not :
    Code:
    http://forums.opensuse.org/english/get-technical-help-here/laptop/457171-acer-aspire-5535-standby-issues.html
    standby works on fedora 14 but hibernation does not and hibernation works on opensuse but standby does not

    I regret to bump an old post guys, but i still have this problem with acer 5535 laptop...but now i really need the suspension feature because i'm using it for the university

    i've noticed there was also a bug report:
    https://bugs.launchpad.net/ubuntu/+s...ux/+bug/948573

    but it expired for inactivity..

    so, is it possible that the only way to get ubuntu suspension/ibernation is to change the laptop itself?

    isn't there a fix/workaround solution?
