I am unable to change the display resolution or detect my monitor

Asked by Bob on 2010-01-09

I was able to run UBUNTU from the CD with no problems. This is the first time I ma using an installed version of LINUX. I have used LINUX from bootable disks a few times.

After installing I am unable to detect my monitor or set the display resolution higher than 800 x 600.
 The only option I can access in visual effects is none.

When I try to detect my monitor nothing happens.
My monitor is a large aging Philips CRT monitor.

I tried to use "Extra" to detect drivers.
I received the following error message "Desktop effects could not be enabled"

I am hoping to use LINUX to do photo editing and screen resolution is CRITICAL.

Hello, I chaged my CPU with 9.04, upgrade to 9.10 and later Installed 10.10 Ubuntu version, all that looking for the best monitor resolution, the same problem plenty of people are reporting how to change if no other option is detected by installed versions
