I just installed ubuntu 11 and the maximum resolution that it will let me set it at is 1024 x 768. My graphics are onboard, its the intel 82845g. Trying to increase the resolution and support the video more smoothly.

UPDATE:

user1@pc1:~$ xrandr | grep maximum
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 2048 x 2048
user1@pc1:~$ gtf 1280 1024 59.9

  # 1280x1024 @ 59.90 Hz (GTF) hsync: 63.49 kHz; pclk: 108.70 MHz

user1@pc1:~$ xrandr --newmode "1280x1024_59.90"  108.70  1280 1360 1496 1712  1024 1025 1028 1060  -HSync +Vsync

Use xrandr to make sure that the new mode can fit within the maximum framebuffer size

xrandr | grep maximum

Use gtf to create a mode line

gtf 1280 1024 59.9

(59.9 is the refresh rate) Add the new mode using xrandr

xrandr --newmode "1280x1024_59.90"  ............

replace the above dots (........) by what the gtf command gives you after the mode is created. It should be something like this: 106.29 1440 1520 1672 1904 900 901 904 932 -HSync +Vsync

Add this newly added mode to the desired output (VGA/LVDS etc - VGA in your case)

xrandr --addmode VGA 1280x1024_59.90

Choose the new mode

xrandr --output VGA --mode 1280x1024_59.90

See a similar question: Can't enable intel driver 82845g/gl (brookdaleg) chipset

Merely speaking, It also indicates that installing Lubuntu solves the issue.
