problems with video-intel driver

Hello,
    I finally tested the settings suggested by Keith and Raul:
1. problem with vbetool - there is really a bug in hibernate package.
Basically, although the vbetool was enabled, the state was not saved
before hibernating the laptop. After correction it works well.

2. frozen laptop after hitting the lid closing switch: it's true that
when keeping the VGA output alived, everything works well. However,
there is one feature that I don't understand:
    - I can only switch on VGA output when an external monitor is
connected. If not, then
             xrandr --output VGA --mode 1280x1024
      complaints about non-existing mode and the output is not activated.
As a result, the laptop still     freezes when closing the lid
   - if I connect the external monitor, activate it and then disconnect
it, xrandr --prop correctly reports only LVDS connected, but I still can
close the lid without freezing the laptop. Only when I switch VGA off
(xrandr --output VGA --off), then laptop freezes again after closing the
lid.
So my question is: can you suggest a workaround to prevent laptop from
freezing or maybe a newer driver release is supposed to solve this issue ?

Then I have another question: when connecting the external monitor
before starting X, the two monitors get auto-detected and I get the
picture on both screens. The mode 1280x1024 is set on VGA (corresponds
to its native resolution), LVDS is set to 1400x1050 as described in
xorg.conf. The problem is that the LVDS screen is somehow "restricted" -
e.g. the bottom toolbar displays a bit shifted from the real bottom. It
seems that effectively LVDS exploits only 1280x1024 area. The other
parts (i.e. outside of 1280x1024 area) of LVDS are also accessible, but
they are not displayed in the VGA.
If I start X without VGA connected and then issue "xrandr --output VGA
--mode 1280x1024", I got another case. The picture in LVDS is preserved
(bottom toolbar is really in the bottom), but it is not visible in VGA.
Basically, the part outside of 1280x1024 area in LVDS is not displayed
in VGA.
Surprisingly, in both cases the output of "xrandr --prop" is the same
(attached).

Is there a way to set up both screens to display the same picture but in
(truly) different resolutions?


Thanks a lot in advance for any hint,

best regards
                              Tomas
