Hello,
I'm experiencing various problems while getting DRI work on my
Acer Travelmate 612TX. This laptopt is equipped with a i815 chipset
with shared memory + 11 mb on board. I'm running a linux-from-scratch
distribution. Initially I used XFree 4.2-release.
Hope, I'm writing to the right persons...
First, I installed linux-2.4.20-rc1 to have the latest DRM modules
installed (i810 1.2.0). Direct rendering was so enabled by the
Xserver on startup but glxinfo was telling me "direct rendering: No".
I then applied the patch that SHOULD solve the problem (instead
of putting a "Option XvMCSurfaces "1") but it didn't work.
So I tried to update to the latest XFree 4.2-cvs trunk (as suggested
by some mailing list). Nothing again.
At this point, using Option XvMCSurfaces to force dri enabling, i tried
to run glxgears: the result was a series of 4 gears stretched and
flickering on my screen.
Then, I download from www.xfree86.org/~alanh the latest i810 kernel module,
and finally DRI and GL rendering worked, BUT while exiting from the X
server I experienced a kernel module crash and my screen blanked.
I can't read (on the screen or into the log) the specific of the kernel
crash: I can only power down my laptop and cry :)
Just a moment before of the blank, anyway, I can clearly identify the
form of a kernel crash, with "Process: X".
Hope this will help you a little bit in the i810 driver development;
anyway, if you need more information or some tests on my system, just ask.
Bye
Alessio
