Now i can change resolution by passing "omapfb.mode=dvi:1024x768MR-24@60" to kernel, but i want to change resolution when system is running.

How can i do ?

    Did you try to change resolution  using fbset utility?

    fbset -fb /dev/fb0 -xres num1 -yres num2

    will change xres to num1 and yres to num2 depending on the numbers you give

    hi Srilatha,

       thanks for you advice.

       when I just change timing by "echo "39272,800/40/80/128,600/1/23/4" > /sys/devices/platform/omapdss/display0/timings" in X windows, the screen become muss, so I set framebuffer by "fbset -fb /dev/fb0 -xres 800 -yres 600" as you suggestted, but It's not full screen.

       I think I should use the tool which X desktop offered to change resolution, such as "xfce4-display-settings".

       maybe  i should change the title to "how can i change resolution in X windows without reboot system".
