DRM/DRI in STABLE

[Charles P. Schaum]

Hi,

Just had a question about DRI/DRM using the Intel i915 module on an
845G. Using fullscreen modes that have a resolution different from the
display at startup can cause the xserver to halt and restart. This
actually happened more under 6.1 STABLE than 6.2-PRE.

After building world I can usually go for about a day or so without this
behavior appearing. Then it will occur and, after the first occurrance,
it will generally have that behavior until a subsequent rebuilding of
world.

I usually avoid this by modifying games so that they either run in a
window or use the default resolution, so there's an easy workaround. I
was just curious if I were doing something dumb or if that's just life
right now.

See below:


I had been getting messages under 6.1-STABLE like:


Sep 21 05:09:07 elbereth kernel: Warning: pid 3307 used static ldt
allocation.
Sep 21 05:09:07 elbereth kernel: See the i386_set_ldt man page for more
info
Sep 21 05:11:52 elbereth kernel: error: [drm:pid3311:drm_close] *ERROR*
can't find authenticator...

But after rebuilding world/kernel to 6.2-PRE (STABLE) these have largely
disappeared - and I still am using the same apps. About the only thing I
see currently are some errors generated when recording a CD via GNOME
(atapicam) which have no effect on my getting a good CD and therefore
which I ignore.


Today's messages were:

The X log really did not indicate anything unusual, save that the server
crashed:
