Just to re-enforce this, I have a colleague who is seeing this on his Radeon-based Lenovo T43 (m300). The display blanks and cannot be resurrected, even CTRL-ALT-BS does not help, but the system is alive. Oddly, I also have a Lenovo T43 based system and it has never shown this problem. It might be something in your xorg setup that is triggering it. If your system is a Radeon, you might try booting with no xorg.conf file. I have found that worked well for my system. Other possibilities include hw.acpi.reset_video=1 (sysctl.conf) and acpi_video_load="YES" (loader.conf). I would like to figure out why my system has no issues while others go off to never-never land. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
