I install the Ubuntu 12.04 on Fujitsu u2010, follow the Ubuntu wiki https://wiki.ubuntu.com/HardwareSupportComponentsVideoCardsPoulsbo#PSB-GFX_drivers
And there are two problems. One is that the screen refresh rate is Zero and I fail to set the screen refresh rate by xrandr command. So the screen look uncomfortable. Another problem is the screen rotation is not working with the psb_gfx driver. And how can I do? Thanks!
