Everything works great except th= at there is a problem with the display when resuming after suspend. I was = wondering if someone could offer some advice on whether it would be possib= le to get this working, and if I could help by providing any relevant info= rmation. The hardware on this machine is pretty new, but it would be great= to get it working :-) I started discussing this a while back on the freeb= sd-mobile mailing list, but couldn't find a workable solution. The origina= l discussion is here http://lists.freebsd.org/pipermail/freebsd-mobile/201= 0-May/011990.html .=0A=0AThe current situation is that the machine will su= =EF=BB=BFspend using acpiconf -s 3 and it will also resume. The problem is= that the LCD display does not resume correctly after suspend - instead it= just stays black. I've been randomly tweaking various things, and get sli= ghtly different results. Sometimes the display stays black in the sense th= e display is still completely switched off. Othertimes, I think the displa= y switches on, but nothing is displayed, so that the display is on but sho= wing nothing except a black background. However, I can still type blind an= d e.g. shutdown/restart the machine.=0A=0A It may help to know that suspen= d/resume works perfectly under the latest Ubuntu 10.04, without any specia= l configuration. I've also updated this machine to the latest BIOS from Le= novo. I've made available a file containing the output or contents of /boo= t/loader.conf, /etc/rc.conf, dmesg, devinfo -vr, acpidump -td, and sysctl = -a. This file can be downloaded from https://files.me.com/geoffrey.ferrari= /oqv857 . I hope somebody will be able to help! At this stage, I'd be very= grateful for any suggestions either on how to fix the problem myself, or = on how to provide the right information to this list to help others to fix= it. Right now, it's only suspend/resume that's keeping me from using Free= BSD as my work OS on a daily basis.=0A=0AIncidentally, does anyone know if= 9-CURRENT would support my Thinkpad better than 8.1?=0A=0AThanks,=0A=0AGe= off=0A=0A=
