NOTE: another issue debian users should be aware of is the failure to reboot on sudo shutdown -r now. The fix is easy though: change GRUB_CMDLINE_LINUX in /etc/default/grub to read GRUB_CMDLINE_LINUX="reboot=pci"
--Start Here ---
The videocard (nvidia quadro something or other) my work Optiplex 990 came with only has a 'displayport', and the supplied adapter for it only has DVI-D (no analogue signal, so a VGA converter won't work). Since my 24" monitor doesn't have DVI, and I hate HDMI, and at the same time appreciate graphics acceleration (can't live without my wobbly windows in compiz), I had to generate an /etc/X11/xorg.conf which would allow me to use the motherboard graphics capabilities. Here's that xorg.conf (ripped out the video card, used smxi to generate an xorg-driver dependent xorg.conf):

15. ORTEP-3 for Windows (Winortep) under Wine
Note: for those who use Mac OS X and get sent here by google, you can also use wine to run ortep3v2. See here for instructions on how to install wine: http://wiki.winehq.org/MacOSX
The installation file can be downloaded from http://www.chem.gla.ac.uk/~louis/software/ortep3/. Install in the same fashion as you would with any other windows program under wine. I will assume that you have installed it in c:\ortep3v2
Request a license the usual way. Make a file called Ortep3-license in the c:\ortep3v2 directory (/home/you/.wine/drive_c/ortep3v2). Put the license information in it:
########################################################################
Program license for : Ortep3 for Windows
User name : XXXXXXXXXX
User email : XXXX@XXXXX.XXX
User affiliation : Department of Chemistry, XXXXX, XXXXX
Windows version : Windows XP
License number : XXXXXXXXXX
########################################################################
So far everything is the same as for a regular windows installation.
The one difference arrives when it comes to setting the ORTEP3DIR variable:
go to the linux shell, type regedit
Navigate to HKEY_CURRENT_USER/Environment
If you don't have the Environment directory, create a new key with that name, then create a string value which you call ORTEP3DIR. Double-click on the data field, and set it to c:\\ortep3v2
You should now be ready to go.

| Winortep can write pov-ray files -- and they are well-written, logical and very easy to read/modify |
 |
| WinOrtep is a full-featured program which can do just about anything. |

14. Evolution email and Google Calendar(s)
The process is already described here:
http://www.ubuntugeek.com/how-to-sync-google-and-evolution-calendars-in-ubuntu.html.
It's not much of a post, but it may be of help to someone who tried the Google option when setting up the calendar sync in Evolution and found it less than satisfactory.
Edit 16/12/2011:
Recently (last two days, version 3.0.3-3) been getting error messages in evolution when trying to connect to my google calendar. While using the method described above for a while I switched to using 'google' instead of 'caldav' as the calendar type at some point. Well, it doesn't work anymore.
Here's how to use google calendar in Evolution:
New -> Calendar
Type -- CalDav
URL: caldav://www.google.com/calendar/dav/myemail%40gmail.com/events/
Use SSL: yes
User name: myemail@gmail.com
User email: myemail@gmail.com
Then clock 'Browse server for calendar and select the
+ /calendar/dav/myemail%40gmail.com/
- myemail@gmail.com
Whether you want to copy content offline or use it as default calendar is a personal choice.
Edit: 16/12/2011 -- 2 hours later
Well, it's not working anymore. Same TLS handshake BS as before.
"Error loading calendar
Cannot open calendar: Unexpected HTTP status code 6 returned (Peer failed to perform TLS handshake)"
What I can't understand is why there is no good description of this problem on the web, given that Evolution is the default email and calendar client for gnome. I don't like thunderbird/icedove+sunbird/iceowl much, but things seem to work better in general there.
