Public bug reported:
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
