Finally, I got the Ubuntu graphics properly work on my Lenovo X201i. It took quite a while and the problem was the graphics card. It would give me blank screen at start-up during the installation, so I gave the kernel the “i915.modeset=0” option according to the advice found after some searching high and low. It worked.

The problem is that it doe snot really quite work… First, the graphics mode is weird, it does not use the accelerator, it seems, so you can’t have the bells and whistles of the interface. That I could live with. The other problem was more serious, the screen would not come back from blank when going to the sleep mode (close the lid).

That second problem was sort of fixed with the option “SAVE_VIDEO_PCI_STATE=true” given to the ACPI (/etc/default/acpi-support). Unfortunately, this never worked reliably and sometimes the computer would freeze on suspend or on resume. Finally, that got me fed up.… -->
