** Attachment added: "unknown.png" https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1733697/+attachment/5012461/+files/unknown.png -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1733697 Title: xserver-xorg-core-dbg does not provide proper debug symbols Status in xorg-server package in Ubuntu: New Bug description: NOTE: This is an issue with the package xserver-xorg-core-dbg but launchpad will not let me file against this. If I collect call-stacks with linux perf utility, then the Xorg process will not show symbols. Everything is listed as [Unknown] Installing the xserver-xorg-core-dbg package is supposed to fix this. But after installing this dbg package, the symbols are still missing. bram@ubuntu64:~$ dpkg --list | grep xserver-xorg-core ii xserver-xorg-core 2:1.18.4-0ubuntu0.7 amd64 Xorg X server - core server ii xserver-xorg-core-dbg 2:1.18.4-0ubuntu0.7 amd64 Xorg - the X.Org X server (debugging symbols) bram@ubuntu64:~$ lsb_release -rd Description: Ubuntu 16.04.3 LTS Release: 16.04 If I record samples with perf, and then view the report, I expect symbol information to show up in the report, provided the xserver- xorg-core-dbg package is installed. Instead, I only see [Unknown] listed for the Xorg process. My guess is the buildid got out of sync, perhaps? bram@ubuntu64:~$ dpkg -L xserver-xorg-core-dbg /. /usr /usr/share /usr/share/doc /usr/share/doc/xserver-xorg-core-dbg /usr/share/doc/xserver-xorg-core-dbg/copyright /usr/lib /usr/lib/debug /usr/lib/debug/.build-id /usr/lib/debug/.build-id/42 /usr/lib/debug/.build-id/42/c7783825afd79435e38d4a44c1f803af7e0ede.debug /usr/lib/debug/.build-id/29 /usr/lib/debug/.build-id/29/7688d51b03d7113a5417f6de68fbe57aa095a7.debug /usr/lib/debug/.build-id/95 /usr/lib/debug/.build-id/95/c6f885e4d38415e1c9c415faa49a4aaf94d3a6.debug /usr/lib/debug/.build-id/0a /usr/lib/debug/.build-id/0a/ec6f336b0afcecec52075749edd8606d0e2c0f.debug /usr/lib/debug/.build-id/ed /usr/lib/debug/.build-id/ed/58714e90f021e7bf8d3e4b9fea98afae3bf26a.debug /usr/lib/debug/.build-id/85 /usr/lib/debug/.build-id/85/94b58beafa25b0afdfe2103da79a237bc80966.debug /usr/lib/debug/.build-id/14 /usr/lib/debug/.build-id/14/d434922be2cce2eb808c66a20806ab5ca3eb68.debug /usr/lib/debug/.build-id/7e /usr/lib/debug/.build-id/7e/f04a35db84d7a294a77b6dcde195041f3bf08b.debug /usr/lib/debug/.build-id/2f /usr/lib/debug/.build-id/2f/e03d62a5fea1e02840854fd11fbcd69275bad9.debug /usr/lib/debug/.build-id/0c /usr/lib/debug/.build-id/0c/c569fa64444ffd714bf6198563a614dbcb9e48.debug /usr/lib/debug/.build-id/ef /usr/lib/debug/.build-id/ef/6b2e5f223b9b54b4f55396b15157f58272f07d.debug /usr/lib/debug/.build-id/d7 /usr/lib/debug/.build-id/d7/87b1937d2c69184d5ccd2fcfef44d3b46872e7.debug /usr/lib/debug/.build-id/62 /usr/lib/debug/.build-id/62/787451bec8c154742e8f8c0ce3350031d20596.debug /usr/lib/debug/.build-id/15 /usr/lib/debug/.build-id/15/1fe43fa88efb1d0baaf0ca815baa6f8d079bfb.debug /usr/lib/debug/.build-id/49 /usr/lib/debug/.build-id/49/166fe55c61663f303afb050b65052676f745a1.debug /usr/share/doc/xserver-xorg-core-dbg/changelog.Debian.gz ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: xserver-xorg-core-dbg 2:1.18.4-0ubuntu0.7 ProcVersionSignature: Ubuntu 4.4.0-98.121-generic 4.4.90 Uname: Linux 4.4.0-98-generic x86_64 NonfreeKernelModules: vtsspp sep4_1 socperf2_0 pax nvidia_uvm nvidia_drm nvidia_modeset nvidia .proc.driver.nvidia.gpus.0000.01.00.0: Error: [Errno 21] Is a directory: '/proc/driver/nvidia/gpus/0000:01:00.0' .proc.driver.nvidia.registry: Binary: "" .proc.driver.nvidia.version: NVRM version: NVIDIA UNIX x86_64 Kernel Module 384.90 Tue Sep 19 19:17:35 PDT 2017 GCC version: gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.5) .proc.driver.nvidia.warnings.fbdev: Your system is not currently configured to drive a VGA console on the primary VGA device.
