The link in your second patch seems wrong. It's pointing to #32527, while this bug is #30527. commit 649293f6b634e6305b6737a841d6e9d0f0065d6c Author: Peter Hutterer <peter.hutterer@who-t.net> Date: Mon Oct 11 16:09:18 2010 +1000 xkb: always fill the symsPerKey array, regardless of client flags (#30527) |

Created attachment 39093 [details] test case illustrating broken xkb keygrabs This issue and resulting test case are from Havoc Pennington; I'm just forwarding on. Running the test case results in an error on recent libX11. First noticed in Ubuntu Lucid, which ships libx11-6 1.3.2. Today, I was able to test top of tree in git and it also results in the same error: Grabbing keysym 0xff50 keycode 0x6e using xkb Sending map changes to server X Error of failed request: BadValue (integer parameter out of range for operation) Major opcode of failed request: 144 (XKEYBOARD) Minor opcode of failed request: 9 (XkbSetMap) Value in failed request: 0x236e0001 Serial number of failed request: 19 Current serial number in output stream: 20 I tested this in an Ubuntu Hardy chroot, which ships 1.1.3, and it ran successfully: Grabbing keysym 0xff50 keycode 0x6e using xkb Sending map changes to server Bound key OK Xkb event received XkbMapNotify I thought that I could try and bisect this, but building the old version of libX11 was a little tricky, and I couldn't get it going. I was able to verify that it was broken in 1.2, but I couldn't build any of the 1.1.x series. So that should at least help you to narrow it down a little. Thanks.
