I'm trying to reinstall an old laptop (Lenovo Thinkpad X60, wi=
th a Core 2 Duo
CPU) with a modern Gentoo Linux, but have run into a problem where every
program trying to use OpenGL segfaults immediately. This makes running e.g.=
KDE
5 a bit difficult. TWM works, though, so I can get X, just not OpenGL.
Here's what GDB thinks of glxgears, but every other program I've managed to
debug crashes in the same way:
(gdb) run
Starting program: /usr/bin/glxgears=20
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib64/libthread_db.so.1".
Running synchronized to the vertical refresh. The framerate should be
approximately the same as the monitor refresh rate.
Program received signal SIGSEGV, Segmentation fault.

(gdb) print fs
$1 =3D (const struct i915_fragment_shader *) 0x0
"fs" comes almost directly from the function argument:
static void calculate_vertex_layout(struct i915_context *i915)
{
const struct i915_fragment_shader *fs =3D i915->fs;
[...]
Then, in the for() loop, trying to dereference "fs" when it is a =
null pointer
is obviously a bad thing.
