Framebuffer device no working on my thinkpad....
I am used to using fbterm under Linux console environment to display non-ANSII texts and using mplayer -vo fbdev2 to play videos.
Now I'm installing Ubuntu 12.04 on a new laptop computer but I find that the framebuffer just won't work at all...All programs using framebuffer to work are down,too...It is not a permission problem for I have already added myself to the Video group... And writing to /dev/fb0 or /dev/fb1 won't create any warning or error message printed out, but the screen won't make any response,either...
Does anyone know what's going on with this situation?
My laptop is a Lenovo ThinkPad E430（3254A71） with two graphic card : NVIDIA GeForce GT 610M＋Intel GMA HD 4000
Any further information can be provided.
I didn't know whether this is a software or hardware issue...so I posted it here..
