I found a pair of bugs (one in the intel driver, one in the X server) which can cause cursor disappearances. I just sent an intel driver patch to the intel-gfx list with the subject: [PATCH] load_cursor_argb is supposed to return a Bool, not void I've posted the X server patch once, and will respond to some review comments. Either is sufficient to get a cursor back, the intel driver one means you get a working hardware cursor again, rather than using a software cursor by mistake. =2D-=20 keith.packard@intel.com --=-=-= Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIVAwUBU0wqWdsiGmkAAAARAQgksw//STLtx9MaoAyKFelY1bfgnC4ZyAYeY4IF dnWcRttzqSay16NtyyP0fYEDr7GdV1OQqgWHmQcqAgmO5C0nY5HaFobG2n7r6+B9 zzdC7MYwgDheUiRb/5uZxm/L6joCdk/H1bvBBdWdNfGTvQ1DY5fmV58mobe72Yv6 TZfSujFQ0WKYWmBedsrs0JJPLyG5E7QQJY2PhZg6V4mgdocK+o1hgfrW/6MMjkpY VTNFr0bKOquZjHz8/wHofHluMm+QU4Ryyu1oyk0cbfhBCHcDcsCs/QMvSvmE9WbV Q7SfnvZr8ZYKJqyvYxbHpIYmW9XqtQ9lQKPWnMHxbnntq9kZThimUswNy5Cc+NwU VSquOTULGkcqPtueFJEyHN+WZReF/3Bqjgfeflh0gz/lm2IAAhEBPHzKqKb7xLyF 0xrcubQwcDI+W+aj5fo7HzwU+QL8cUnkPO3vX299jSH1bd2QeEPUtGpqZcVKff1b sNDMYFytJOK935deuIfCQ3t2MR28/G8KG41E2IH5m8ii/NrYEphQTaqZYXoQIr/B 1G0YprgsrWASI3k+NfpExgwQQFBDKDS9BX3+7LOfAKdkRzXsh74SAEAyOI6ymfqt nNHiBhuSZU3tCvFn3IdvVNJ3jU9NqrB7T3Ijoxvk0aPMW0Cdv9OwNlcM8NxEeun5 u4lkloR7tK0= =uirL -----END PGP SIGNATURE----- --=-=-=-- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
