Hi Mathieu, what's your video card? $ lspci | grep -i vga will do it.
0:41 mathieu@kubrick ~ % lspci | grep -i vga 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
Also: 1. do you have installed acpi,
no
laptop-mode-tools
no.
or pm-utils?
yes, required bu upower, required by gdm Do you think i need to install them ? (it worked well without them until gnome 3.6)
2. what does happen if you suspend your system using the pm-suspend tool?
it wake up correctly (without locking screen)
A $ man pm-suspend will give you useful data about the quirks flags you can use.
my problem is not to suspend the laptop, only wake up when have been suspending by gnome cause idling. -- Mathieu R. http://400iso.net/
