Thanks for this hint, this spread some light on the problem, there seems to be a lots of fixes for this, i found this too : http://lists.freedesktop.org/archives/dri-devel/2013-October/047941.html Maybe Lenovo may fix this in the BIOS (reporting ?) or intel may fix the driver, not very easy to know :-) But for now I can live with my solution, as I use suspend/resume on a daily basis (i hate rebooting my workspace) :-) /BL ------------------------------------------------------------------------------ _______________________________________________ ibm-acpi-devel mailing list ibm-acpi-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/ibm-acpi-devel
