    Re: After suspending and waking up, the screen flickers

    Thanks editrix,

    I hope I get a solution too. I'm just starting to get my head around Ubuntu (and like it) and don't fancy the hassle of changing OS right away, I'll hang on for the meantime to see if anyone else can come up with anything... I need my suspend!!! At the moment I am shutting down after each time I check my email...

    Many thanks anyway.

    Can no one offer ideas on this, please...

    (please see my previous posts)

    If no one can help this time then I'll just give up and live with it... Or change my OS!
    Thank you.

    Don't bother switching to Mint for this. I'm on Isadora and having the same problem for the first time ever. Had the previous to iterations of Mint/Ubuntu on the same laptop with no such problems.

    Re: After suspending and waking up, the screen flickers

    I ran into this problem on 12.04.2 when using 'rtcwake' through cron to put the file server to sleep when nobody is around or everyone is sleeping and having it automatically wake up right before people get home from work or early in the morning on weekends. Whenever the computer wakes up from suspend, the screen randomly flickers, generally more when scrolling.

    The 'sleep.sh' command doesn't seem to have this problem. Taking these 5 lines from sleep.sh and adding them to my script right before I call 'rtcwake' seems to solve the problem.

    Code:
    . /etc/default/acpi-support
    . /usr/share/acpi-support/power-funcs
    . /usr/share/acpi-support/device-funcs
    . /usr/share/acpi-support/policy-funcs
    
    DeviceConfig;
    I haven't tried to reverse engineer what those 5 lines do yet, but the solution seems to lie in there. Each of those files it's executing seem to contain various functions that get called through the "DeviceConfig" function, and so one of those functions must do something to the display to cause this problem not to show up.
