Customizing your login on Purdue CS computers (WIP)
=============================================
---
date: "2014-04-21"

Most CS students at Purdue spend a lot of time on the lab boxes, but
don't know a lot about them. This document tries to fix that.
The lab boxes all run Gentoo.
## About GDM
They run `gdm` (Gnome Display Manager) 2.20.11 for the login screen.
This is an old version, and has a couple behaviors that are slightly
different than new versions, but here are the important bits:
System configuration:
- `/usr/share/gdm/defaults.conf` (lower precidence)
- `/etc/X11/gdm/custom.conf` (higher precidence)
User configuration:
- `~/.dmrc` (more recent versions use `~/.desktop`, but Purdue boxes
aren't running more recent versions)
## Purdue's GDM
Now, `custom.conf` sets
BaseXsession=/usr/local/share/xsessions/Xsession
SessionDesktopDir=/usr/local/share/xsessions/
This is important, because there are *multiple* locations that look
like these files; I take it that they were used at sometime in the
past. Don't get tricked into thinking that it looks at
`/etc/X11/gdm/Xsession` (which exists, and is where it would look by
default).
Values for `~/.dmrc:Session`:
- `custom`: Executes `~/.xsession`
- `default`: Executes ~/.Xrc.cs
- `fvwm2`: ???
- `gnome`: ...
- `kde`: Displays a message saing KDE is no longer available
- `failsafe`: Runs a single xterm window (NOPE)
