Hello.
I don't have a patch, as I can't still make it run on VMWare.
But tests on other graphic card can be good.
I have attached the file.
There is no Cairo code, no page_flip and
I have also added drmModeDirtyFB, as Jakob from vmware suggested to make it
work under vmwgfx.
Regards.

Hello.
I have a question about libdrm/libkms and test/modetest/modetest.c.
I am now working with vmwgfx + VMWare 7.0, where vmwgfx had correctly
initialized framebuffer and also now using fbcon.
Now I want to test it woth modetest.c
This program is only for intel so i recoded it to use libkms functions.
Could you send the changes to make modetest.c use libkms as a patch?
It's a good idea.
cheers,
Kristian
