Travelmate is a series of laptops made by Acer?.
On a standard setup of Ubuntu Dapper? on a Travelmate 230, the display will only come up at 640x480, using the i810 video driver. To fix this, go into the BIOS on boot, go to the Advanced section, and set the memory allocated to the video (called UMA) from 1Mb to 8Mb. Then when you next start it up, X will be running at 1024x768.
