change screen resolutino with fbdev24 for consumer II?

Hi all,

I want to change the screen resolution with the framebuffer driver fbdev for a consummer II-based embedded system:

- Linux kernel 2.4

- video driver: STPC fbdev24, compiled into the kernel

- default resolution: 800X600, set by a line vga=788 in the lilo.conf file

After the system boots up, I want to be able to change the default screen resolution to any supported resolution by this driver, for instance, to 1024X768 or 600 X 480. However, when I did this with ''fbset -xres 1024 -yres 768'', I got a message from the driver, ''WARNING: Graphics mode not supported''.

Therefore, my question is:

How to change the screen resolution after the system boots up? Do I need to modify the driver code to achieve this? Any suggestions?

Thanks and best,

JP
