[[!meta title="Tips for debugging"]]
Append debug on the boot command line, in order to access a default instance
of the dwm window manager.
Once X is booted, press shift+alt+enter together to make dwm (the window manager) launch a terminal emulator.
Alternatively, you can press ctrl+alt+F2 to switch out of X to tty2 and log in there as webc with no password. This also works if X didn't start.
This only works when debug is on the commandline.

chrome=debug
Use the log= [[API]] and grab an account with Papertrail for a nice Web interface
Hold Alt or Shift keys on the install boot to get boot: prompt
This will not work if noescape is being used beforehand.
You may need to remove /etc/dpkg/dpkg.cfg.d/exclude-files to get your headers, before installing build-essential et al.
As the root super-user sudo -i, utilise the p tool to paste you logs into.
- Implented in https://github.com/Webconverger/webc/blob/master/root/.bashrc
- Example:
grep upgrade.sh /var/log/daemon.log | p
Basically all we need is the Xorg file which we can get via support.
Booting Webconverger by default will forcefully fast forward to https://github.com/Webconverger/webc/commits/master
You probably don't want this behaviour if you are testing a change, so append noupgrade.
# cat /proc/net/netstat | p
Useful for calculating rough sizes of upgrades.
Putting at the top of your script
exec >/tmp/${0}$$.log 2>&1
set -x
Creates a complete log file in /tmp
Boot with debug in cmdline and as root sudo -i.
apt-get update && apt-get install scrot suckless-tools
Using dwm's default dmenu shortcut, [Alt]+p and choosing scrot and append the
filename, like /tmp/test-rendering.png
From there you can use http://imgur.com/ to upload the PNG file and get the URL to paste into a bug report.
You can edit things and restart X by running pkill X as root.
Assuming you have a configuration like so http://dabase.com/blog/Sharing_an_Internet_connection_in_Archlinux/
Setup Virtualbox with the Bridged Adaptor eth0.
To disable access to the configuration server:
iptables -I FORWARD 1 -d config.webconverger.com -j REJECT
To clear the above rule:
iptables -F FORWARD
By typing
support as
root, you will send your /var/log contents to our support
service, which is for customers.
Boot without "vga=771 quiet splash"
Then... you're not going to like this. Try all of these kernel cmdline options:
memtest noapic noapm nodma nomce nolapic nomodeset nosmp nosplash vga=normal
Refer to the [[wireshark]] guide.
systemd.confirm_spawn=1
I host a test.js on my local httpd and configure Firefox on Archlinux like so.
Use cups-pdf and a stanza like:
printer=Printer,http://printer:631/printers/Virtual_PDF_Printer,drv:///sample.drv/generpcl.ppd
Please watch the How printing is tested on Webconverger with a Virtual PDF printer video for a walkthrough.
