    Re: Fail to resume from sleep

    I have an HP Pavilion dv6353us and I had the same problem for a while but I found a workaround with KDE. I enabled power management (can't remember how to do it and I'm writing this post on Windows XP atm) and set the monitor sleeping times how I wanted. Ever since, i never had that black screen problem. Hope this helps.

    Thanks for your reply, Merdril.

    I don't understand what you mean by "enabled power management" -- this should always be running on a laptop anyway. I can certainly already set monitor sleep times etc. on my laptop, but it makes no difference to the broken DPMS control in Hardy.

    I have the same problem, and I solve it by just entering my password then enter, I figure I just can't see the field.

    Try it out, it works for my on my dell laptop.

    Re: Fail to resume from sleep

    Hi everyone,
    I also had a "fail to resume" problem, although mine has probably a different cause from yours, but I managed to get resume to work by using
    Code:
    sudo /etc/acpi/sleep.sh force
    to get the laptop to sleep. By doing so, it does resume fine, although I still get the high pitch noise.
    Let me know if it helps.

    Re: Fail to resume from sleep

    I seem to have been able to fix this problem by executing

    Code:
    sudo dpkg-reconfigure -phigh xserver-xorg
    The replacement /etc/X11/xorg.conf is very much shorter than the previous version which the dpkg reconfigure replaced: in particular, it contains no information about available screen modes. Yet, it seems to work. I assume something in my older xorg.conf was breaking the DPMS resume.

    Re: Fail to resume from sleep

    I was able to "fix" this issue by downgrading my video card driver. I have an nVidia GO 6150 and it was running on the restricted driver that Hardy Heron automatically found. To downgrade the driver, I installed the envy-ng package, ran the EnvyNG application (in Applications -> System Tools -> EnvyNG), and selected to install the NVIDIA driver version 96.43.05. This also fixed another (possibly related) issue where I could only see a blank screen instead of a tty terminal when I hit any of ctrl+alt+F1 through ctrl+alt+F6. However, I am still experiencing frequent system-wide video freezes, but they may be related instead to compiz-fusion.

    I should note that I had none of these problems in Gutsy.
