Here, closing displays shall happen in the same order as they were opened, -OR- shall not be closed at all! Otherwise some driver related bug appears and brings down the JVM with an SIGSEGV. You may test this, ie just reverse the destroy order below. See also native test: jogl/test/native/displayMultiple02.c (attached) 1067 1 sgothel 2011-08-31 15:39:23 +0200 Since we cannot fix the driver .. this is a workaround avoiding SIGSEGV. We don't close the X11 Display connection if driver vendor is ATI via 'X11Util.markDisplayUncloseable(true)'. This is currently exercised in X11GLXDrawableFactory shared resource initialization. FIXME: To allow this workaround to function w/o JOGL usage, this detection and setting shall happen in X11Util itself, if we could query the driver vendor w/o GLX. 265 2011-08-31 15:28:22 +0200 2011-08-31 15:28:22 +0200 Multiple X11 Display Connection Test displayMultiple02.c text/x-csrc 3339 sgothel LyoqCiAqIGNvbXBpbGUgd2l0aDogZ2NjIC1vIGRpc3BsYXlNdWx0aXBsZTAyIGRpc3BsYXlNdWx0 aXBsZTAyLmMgLWxYMTEgLWxHTAogKi8KCiNpbmNsdWRlIDxzdGRpby5oPgojaW5jbHVkZSA8WDEx L1guaD4KI2luY2x1ZGUgPFgxMS9YbGliLmg+CiNpbmNsdWRlIDxYMTEvWHV0aWwuaD4KI2luY2x1 ZGUgPEdML2dseC5oPgojaW5jbHVkZSA8R0wvZ2wuaD4KCnN0YXRpYyB2b2lkIHRlc3RPcmRlcihp bnQgcmV2ZXJzZURlc3Ryb3lPcmRlciwgY29uc3QgY2hhciAqIG1zZyk7CgppbnQgbWFpbihpbnQg bmFyZ3MsIGNoYXIgKip2YXJncykgewogICAgdGVzdE9yZGVyKDAsICJOb3JtYWwgb3JkZXIiKTsK ICAgIHRlc3RPcmRlcigxLCAiUmV2ZXJzZSBvcmRlciIpOwogICAgcmV0dXJuIDA7Cn0KCnN0YXRp YyB2b2lkIGNyZWF0ZUdMV2luKERpc3BsYXkgKmRweSwgaW50IHdpZHRoLCBpbnQgaGVpZ2h0LCBX aW5kb3cgKnJXaW4sIEdMWENvbnRleHQgKnJDdHgpOwpzdGF0aWMgdm9pZCB1c2VHTChEaXNwbGF5 ICpkcHksIFdpbmRvdyB3aW4sIEdMWENvbnRleHQgY3R4LCBpbnQgd2lkdGgsIGludCBoZWlnaHQp OwoKdm9pZCB0ZXN0T3JkZXIoaW50IHJldmVyc2VEZXN0cm95T3JkZXIsIGNvbnN0IGNoYXIgKiBt c2cpIHsKICAgIGludCBtYWpvciwgbWlub3I7CiAgICBEaXNwbGF5ICpkaXNwMTsKICAgIFdpbmRv dyB3aW4xOwogICAgR0xYQ29udGV4dCBjdHgxOwoKICAgIERpc3BsYXkgKmRpc3AyOwogICAgV2lu ZG93IHdpbjI7CiAgICBHTFhDb250ZXh0IGN0eDI7CgogICAgZnByaW50ZihzdGRlcnIsICIlczog Q3JlYXRlICMxXG4iLCBtc2cpOwogICAgZGlzcDEgPSBYT3BlbkRpc3BsYXkoTlVMTCk7CiAgICBj cmVhdGVHTFdpbihkaXNwMSwgMjAwLCAyMDAsICZ3aW4xLCAmY3R4MSk7CiAgICB1c2VHTChkaXNw MSwgd2luMSwgY3R4MSwgMjAwLCAyMDApOwoKICAgIGZwcmludGYoc3RkZXJyLCAiJXM6IENyZWF0 ZSAjMlxuIiwgbXNnKTsKICAgIGRpc3AyID0gWE9wZW5EaXNwbGF5KE5VTEwpOwogICAgY3JlYXRl R0xXaW4oZGlzcDIsIDMwMCwgMzAwLCAmd2luMiwgJmN0eDIpOwogICAgdXNlR0woZGlzcDIsIHdp bjIsIGN0eDIsIDMwMCwgMzAwKTsKCiAgICBpZihyZXZlcnNlRGVzdHJveU9yZGVyKSB7CiAgICAg ICAgZnByaW50ZihzdGRlcnIsICIlczogRGVzdHJveSAjMlxuIiwgbXNnKTsKICAgICAgICBnbFhN YWtlQ3VycmVudChkaXNwMiwgMCwgMCk7CiAgICAgICAgZ2xYRGVzdHJveUNvbnRleHQoZGlzcDIs IGN0eDIpOwogICAgICAgIFhDbG9zZURpc3BsYXkoZGlzcDIpOwoKICAgICAgICBmcHJpbnRmKHN0 ZGVyciwgIiVzOiBEZXN0cm95ICMxXG4iLCBtc2cpOwogICAgICAgIGdsWE1ha2VDdXJyZW50KGRp c3AxLCAwLCAwKTsKICAgICAgICBnbFhEZXN0cm95Q29udGV4dChkaXNwMSwgY3R4MSk7CiAgICAg ICAgWENsb3NlRGlzcGxheShkaXNwMSk7CiAgICB9IGVsc2UgewogICAgICAgIGZwcmludGYoc3Rk ZXJyLCAiJXM6IERlc3Ryb3kgIzFcbiIsIG1zZyk7CiAgICAgICAgZ2xYTWFrZUN1cnJlbnQoZGlz cDEsIDAsIDApOwogICAgICAgIGdsWERlc3Ryb3lDb250ZXh0KGRpc3AxLCBjdHgxKTsKICAgICAg ICBYQ2xvc2VEaXNwbGF5KGRpc3AxKTsKCiAgICAgICAgZnByaW50ZihzdGRlcnIsICIlczogRGVz dHJveSAjMlxuIiwgbXNnKTsKICAgICAgICBnbFhNYWtlQ3VycmVudChkaXNwMiwgMCwgMCk7CiAg ICAgICAgZ2xYRGVzdHJveUNvbnRleHQoZGlzcDIsIGN0eDIpOwogICAgICAgIFhDbG9zZURpc3Bs YXkoZGlzcDIpOwoKICAgIH0KCiAgICBmcHJpbnRmKHN0ZGVyciwgIiVzOiBTdWNjZXNzIC0gbm8g YnVnXG4iLCBtc2cpOwp9CgovKiBhdHRyaWJ1dGVzIGZvciBhIGRvdWJsZSBidWZmZXJlZCB2aXN1 YWwgaW4gUkdCQSBmb3JtYXQgd2l0aCBhdCBsZWFzdAogKiA0IGJpdHMgcGVyIGNvbG9yIGFuZCBh IDE2IGJpdCBkZXB0aCBidWZmZXIgKi8Kc3RhdGljIGludCBhdHRyTGlzdERibFtdID0geyBHTFhf UkdCQSwgR0xYX0RPVUJMRUJVRkZFUiwgCiAgICBHTFhfUkVEX1NJWkUsIDQsIAogICAgR0xYX0dS RUVOX1NJWkUsIDQsIAogICAgR0xYX0JMVUVfU0laRSwgNCwgCiAgICBHTFhfREVQVEhfU0laRSwg MTYsCiAgICBOb25lIH07Cgp2b2lkIGNyZWF0ZUdMV2luKERpc3BsYXkgKmRweSwgaW50IHdpZHRo LCBpbnQgaGVpZ2h0LCBXaW5kb3cgKnJXaW4sIEdMWENvbnRleHQgKnJDdHgpCnsKICAgIGludCBz Y3JlZW4gPSBEZWZhdWx0U2NyZWVuKGRweSk7CiAgICBYVmlzdWFsSW5mbyAqdmkgPSBnbFhDaG9v c2VWaXN1YWwoZHB5LCBzY3JlZW4sIGF0dHJMaXN0RGJsKTsKICAgIENvbG9ybWFwIGNtYXA7CiAg ICBYU2V0V2luZG93QXR0cmlidXRlcyBhdHRyOwoKICAgIC8qIGNyZWF0ZSBhIEdMWCBjb250ZXh0 ICovCiAgICAqckN0eCA9IGdsWENyZWF0ZUNvbnRleHQoZHB5LCB2aSwgMCwgR0xfVFJVRSk7CiAg ICAvKiBjcmVhdGUgYSBjb2xvciBtYXAgKi8KICAgIGNtYXAgPSBYQ3JlYXRlQ29sb3JtYXAoZHB5 LCBSb290V2luZG93KGRweSwgdmktPnNjcmVlbiksIHZpLT52aXN1YWwsIEFsbG9jTm9uZSk7CiAg ICBhdHRyLmNvbG9ybWFwID0gY21hcDsKICAgIGF0dHIuYm9yZGVyX3BpeGVsID0gMDsKCiAgICAv KiBjcmVhdGUgYSB3aW5kb3cgaW4gd2luZG93IG1vZGUqLwogICAgYXR0ci5ldmVudF9tYXNrID0g RXhwb3N1cmVNYXNrIHwgS2V5UHJlc3NNYXNrIHwgQnV0dG9uUHJlc3NNYXNrIHwKICAgICAgICBT dHJ1Y3R1cmVOb3RpZnlNYXNrOwogICAgKnJXaW4gPSBYQ3JlYXRlV2luZG93KGRweSwgUm9vdFdp bmRvdyhkcHksIHZpLT5zY3JlZW4pLAogICAgICAgIDAsIDAsIHdpZHRoLCBoZWlnaHQsIDAsIHZp LT5kZXB0aCwgSW5wdXRPdXRwdXQsIHZpLT52aXN1YWwsCiAgICAgICAgQ1dCb3JkZXJQaXhlbCB8 IENXQ29sb3JtYXAgfCBDV0V2ZW50TWFzaywgJmF0dHIpOwoKICAgIFhNYXBSYWlzZWQoZHB5LCAq cldpbik7Cn0KCnZvaWQgdXNlR0woRGlzcGxheSAqZHB5LCBXaW5kb3cgd2luLCBHTFhDb250ZXh0 IGN0eCwgaW50IHdpZHRoLCBpbnQgaGVpZ2h0KQp7CiAgICBnbFhNYWtlQ3VycmVudChkcHksIHdp biwgY3R4KTsKICAgIGdsU2hhZGVNb2RlbChHTF9TTU9PVEgpOwogICAgZ2xDbGVhckNvbG9yKDAu MGYsIDAuMGYsIDAuMGYsIDAuMGYpOwogICAgZ2xDbGVhckRlcHRoKDEuMGYpOwogICAgZ2xWaWV3 cG9ydCgwLCAwLCB3aWR0aCwgaGVpZ2h0KTsKICAgIGdsQ2xlYXIoR0xfQ09MT1JfQlVGRkVSX0JJ VCB8IEdMX0RFUFRIX0JVRkZFUl9CSVQpOwogICAgZ2xYU3dhcEJ1ZmZlcnMoZHB5LCB3aW4pOwog ICAgZ2xYTWFrZUN1cnJlbnQoZHB5LCAwLCAwKTsKfQoK
