Solaris 10 graphic problem :Tombé en marche

Well, you know that's the french expression to say you didn't do anything and it started working...
Yes, it worked...FYI, the parameters I used are :
Xsun :
Video Device : Intel I810/815 (4Mb)
Video Driver : I810
Resolution : 1024x768 - 256 colors at 75Hz
Screen size : 17-inch

I did two things which I don't know if that saved me :
I installed xf86-4.4.0-video.pkg.bz2 (SUNWxf86r and SUNWxf86u), I found on the web.
And electrically stopped the PC.
Rebooted, BINGO : gave me I810 choice.

Now, I feel better. :-)
