I recently installed Xubunut 11.04 on an old notebook laptop, and wanted to run a dual monitor setup using an external monitor. The laptop ships with Intel Graphics Media Accelerator 900, and I’m using this display controller:
kenneho@laptop:~$ lspci |grep Display
00:02.1 Display controller: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 04)
My external monitor is running with a 1280×1024 resolution, and are placed on the left hand side of the laptop.
