I switched it to Ubuntu around a year back when I first started using Ubuntu. At the time, I was using a regular CRT monitor and when I installed Ubuntu it set the resolution to 800x600. After some tinkering I managed to get it to 1024x768 (unfortunately I now forget how I managed that). However, a few months later I had to relocate my office, and in the course of shifting the CRT VGA monitor, it met its end. As a replacement I bought an Acer 15 inches x153W LCD monitor.
> The trouble is that now Ubuntu does not allow me to change or set the resolution any higher than the 1024x768. I know the monitor is capable of handling 1280x1024, but I have been unable to figure out how to get it to perform at this level. In the mean time, I also upgraded to Ubuntu 9.10 - everything on the system works fantastically well except for the inability to reset the monitor resolution to my liking.
Does you system have a separate graphics card attached or is the
monitor connected to the onboard (intel) card? If you're using an
Nvidia or ATI card, you may need to install more drivers.

The other possibility is that Ubuntu may be using VESA (generic)
drivers for your make of card, causing it to max out at 1024x768. Can
you please post the outputs of running the following commands in the

$ glxinfo | grep "direct rendering"


$ lspci -nn | grep VGA
