Dear Dr Kulzer, thanks for the hints.
I did the following:
apt-get install hibernate
that installed also vbetool
I tried to read the manuals, but I did not understand properly what I'm suppose to do.
But at least, I finally understand the difference between "suspend" and "hibernate".
When I tried to "suspend" the computer (pressing Fn-moon), it failed but I had a pop-up addressing me to
http://people.freedesktop.org/~hughsient/quirk/There I find many useful information, but stil I'm not able to suspend the computer correctly.
I modified "i810" in "intel" in the xorg.conf file, as requested by ./quirk-checker.sh and, as far as I can understand, I must use the quirk "--quirk-s3-bios" to the pm-suspend command.
If i write pm-suspend--quirk-s3-bios, everything seems to work fine, but I do not know where to write this option permanently.
Here (/
http://www.thinkwiki.org/wiki/Problem_with_display_remaining_black_after_resume) it is suggested to write
DISPLAY_QUIRK_S3_BIOS=\"true\" into /etc/pm/config.d/config for FC7.
I did it, but seems not to work with debian.
Moreover, in the manual for pm-suspend I read
FILES
/etc/pm/config.d
The files in this directory are evaluated in C sort order. These
files can be provided by individual packages outside of pm-utils.
If a global configuration variable is set, the value set to will be
appended to the previous value. If any other variable is set, it
will be ignored. The syntax is simply: VAR_NAME = value. See the
CONFIGURATION VARIABLES section for valid variables defined by
pm-utils. External packages can define others, see their respective
documentation for more information.
and the CONFIGURATION VARIABLES section below in the manual seem not to report
DISPLAY_QUIRK_S3_BIOS=\"true\" as a valid variable.
I think that there are some files where I have to write some options, but I'm unclear where they are and in which order they are read/executed
Any hint as to where to learn such things?
Moreover, coming back to hibernate, in the hibernate manual I see that I should compile the kernel in order to let "hibernate" work. Is that true ?
From dmesg I have not any tuxonice non suspend2 item
I went to the
http://www.tuxonice.net/ but there there are not yet the directions on how to recompile the kernel.
Thanks again
Ottorino
The configuration files are in /etc/hibernate/. Install the "hibernate"
and "vbetool" packages and read the documentation.
