Debugging Chromium on Linux

browser.md

Use the following to get runtime logs:

browser() {
    chromium-browser --ozone-platform=wayland --enable-features=UseOzonePlatform,VaapiVideoDecoder --allow-sandbox-debugging --enable-logging=stderr --v=1 "$@"
}

After enabling coredumps (see instructions here), test chromium dumps cores to /var/coredumps:

WARNING: This will kill all running Chromium processes. Potentially sensitive information will be in the coredumps. Delete them after encrypting and sending them to your systems engineer.

pid=$(pgrep chromium)
kill -SIGQUIT $pid
ls -la /var/coredumps

enable_core_dumps.md

Add the following to /etc/security/limits.conf:

* soft core unlimited
* hard core unlimited

Add this to /etc/sysctl.conf:

kernel.core_pattern=/var/coredumps/core.%e.%p.%h.%t
fs.suid_dumpable=1

Apply changes:

sudo sysctl -p

Append this to ~/.bashrc.local:

ulimit -c unlimited

Create a directory for the coredumps and give write permission for all:

sudo mkdir -p /var/coredumps && sudo chmod a+w /var/coredumps
