Hi Bruno,
Thanks for your reply. I have recompiled the Linux kernel with
CONFIG_DRM_I915
enabled, with the updated kernel file my display is looking strange. i.e. I
have
vga=791
option in my boot configuration file and with this actual graphics screen is
displayed only
in quarter area of screen. Which is reapting twice, covering left and right
quarter of screen,
rest screen is black(i.e.bottom half of the screen).
How can I solve this problem? Please help me.
With the latest Kernel file with CONFIG_DRM_I915 enabled, how do I set
different
screen resolutions. Please let me know.
Thanks & Best Regards,
Sanjay

Hi,
You should look at KMS (Kernel Mode Setting) with i915 driver that you
find under DRI. (CONFIG_DRM_I915 + CONFIG_DRM_I915_KMS)
KMS can also be manually enabled/disabled with i915.modeset kernel
parameter when i915 is built-in.
VESA only knows a few standard predefined modes but not the wide
resolutions currently seen. It's based on some BIOS code and can only
set resolution at early system boot, does not support s2ram (S3) nor any
acceleration.
