i searched google and get some info that it relate to a tp_smapi module, and many newest laptops are not getting support by linux kernel.

Strange, my T440 doesn't seem to have any problems on my Gnome setup. Are you talking about DisplayPort or VGA?
Comment by goodman Leung (gbcbooks) - Saturday, 09 January 2016, 03:04 GMT
Yes, the vga port .
I restarted system when upgrade completed, it worked fine, but it crash and stuck since i activated the vga port to extent my screen to a display.

FYI the DisplayPort output works fine on the latest kernel so you could switch over to using that if you wanted. This sounds like it might be more of an upstream issue than a problem with packaging. I'd recommend you report the issue upstream to the Linux kernel developers.
