Hi,
My laptop, an HP Envy 17, has been running NetBSD (among others) -current
since I've had it, almost seven years ago. It has an Intel 530 graphics, as
well as NVidia GeForce GTX 950m, the latter has never worked for me under
NetBSD, to get Xorg running, I usually run 'Xorg -configure' and get rid of
all the configured options - screen, device, monitor - relating to the
NVidia card.
Up until 10.99.2 as of 03/01/2023, all was fine, more or less; Xorg ran
using DRI2, everything was accelerated as expected, I didn't even have some
of the graphics glitches which appeared previously.
This morning I upgraded the instance to my yesterday's build - as of
07/01/2023. Now Xorg dumps core as follows:
-
Reading symbols from /usr/X11R7/bin/Xorg...
(No debugging symbols found in /usr/X11R7/bin/Xorg)
[New process 3404]
[New process 3397]
[New process 3229]
[New process 3555]
Core was generated by `Xorg'.
Program terminated with signal SIGABRT, Aborted.

startx results in (I guess the same):

The same build appears to be working fine on the build machine using
..
radeon0 at pci1 dev 0 function 0: ATI Technologies FirePro W5000 (rev.
0x00)
..
(again, decent DRI2 performance here).
I tried the kernel from the previous build - which was working OK - but
obviously it didn't work, as the problem appears to be in
/usr/X11R7/lib/modules/dri/i965_dri.so .
I examined the cvs changes between 03/01 and 07/01 and could not find
anything directly related to Intel graphics, with the possible exception
of:
