patch for suspend/resume problems in laptop asus Z53F

[Manuel Carrasco]

Binary package hint: 915resolution

The problem occurs when :
1- I start my laptop in 1280x800 graphical mode (using 915resolution).
2- I suspend/hibernate from graphical mode (using gdm buttons)
3- After the resume process, the graphical screen is wrong.

This problem does not occurs when i follow these steps:
1.- I start the laptop in graphical mode
2.- I switch to tty1 in text mode (ctrl-alt F1)
3.- I login and run: sudo "/usr/sbin/pmi action sleep"
4.- I resume my laptop.
5.- I switch to graphical mode in tty7 (ctrl-alt F7).

So I've written two scripts that solve the problem:
1.- suspend script: /etc/acpi/suspend.d/06-915-resolution-chvt.sh
#!/bin/sh
if [ -x /usr/sbin/915resolution -a -x /usr/bin/chvt -a -x /bin/fgconsole ]; then
    . /etc/default/915resolution
    if [ "$MODE" = auto ] || [ -n "$MODE" -a -n "$XRESO" -a -n "$YRESO" ]; then
        C=`/bin/fgconsole`
        if [ -n "$C" -a "$C" != 1 ]; then
                /usr/bin/chvt 1
                echo "$C" > /var/tmp/915-resolution-previous-vt
        fi
    fi
fi
2.- resume sctript: /etc/acpi/resume.d/97-915-resolution-chvt.sh
#!/bin/sh
if [ -x /usr/sbin/915resolution -a -x /usr/bin/chvt -a -f /var/tmp/915-resolution-previous-vt ]; then
    . /etc/default/915resolution
    if [ "$MODE" = auto ] || [ -n "$MODE" -a -n "$XRESO" -a -n "$YRESO" ]; then
        C=`cat /var/tmp/915-resolution-previous-vt`
        [ -n "$C" ] && /usr/bin/chvt $C
    fi
    rm -f /var/tmp/915-resolution-previous-vt
fi

Could you please recheck it with latest Ubuntu Gutsy Gibbon 7.10 or the Live CD? 915 resolution has become obsolete in Gutsy since the new Intel driver is used.

Intel driver in gutsy works fine.

Thank you
