The notebook now supports image inclusion via html: this is better as the formatting is simple(r) and the functionality is built in.

nvidia ubuntu 3D acceleration broken
Turned computer on. Previously working. Now not. Reason unknown. Login screen is in chunko-vision. Fluxbox looks terrible. Logging out and returning to the login screen restores normal resolution (WHY?!). Logging into 3D Unity looks ok but I think is sluggish.
Now I have to spend some of the little free time I have dicking around trying to get this working again.
I had the nvidia closed source driver working ok.
So, some commands and results:

*snip* I eventually uninstalled everything and used bumblebee only (in case it helps you solve my problem or for people having a hard time installing their nvidia drivers).*snip*
Hmmm. Following something from that page:
me@me:~$ nvidia-detector
none
Odd. The page did not show a resolution and mentioned use of bumblebee. I don't thing I used it: apt-get doesn't know it. My video was working fine a few days ago......
So I looked in /var/log/:
me@me~: ls -lha /var/log/Xorg*
This showed a new file and an old one (from a couple of weeks ago, when things were ok). Differences:

So lshw appears to detect the card but shows its clock to be at 33MHz? Odd.

*snip* I eventually uninstalled everything and used bumblebee only (in case it helps you solve my problem or for people having a hard time installing their nvidia drivers).*snip*
Hmmm. Following something from that page:
me@me:~$ nvidia-detector
none
Odd. The page did not show a resolution and mentioned use of bumblebee. I don't thing I used it: apt-get doesn't know it. My video was working fine a few days ago......
So I looked in /var/log/:
me@me~: ls -lha /var/log/Xorg*
This showed a new file and an old one (from a couple of weeks ago, when things were ok). Differences:

So it looks like the nvidia driver is not being loaded. Later,

More confirmation of a driver problem. Later the broken one (the current one) showed,

while the old, working log had no mention of nouveau.
OK. I'm going to uninstall my video drivers as best I can and start this again..... Nervous. Back to unity and I'll turn off the video drivers.

I removed it via the settings menu. A reset and now resolution looks normal but /var/log/Xorg.0.log shows the same nvidiacomplaints as above. Why is it even being looked for now? It seems that video driversare not well managed in ubuntu. :( me@me:~$ sudo nvidia-xconfig
WARNING: Unable to locate/open X configuration file.
New X configuration file written to '/etc/X11/xorg.conf' That's new. Before I removed the driver, there was a different complaint. I checked the linux headers, they seem fine.Restart again now the new xorg.conf has been written. Oh good. Back to low resolution. :( Checking the xorg log file, there is still no nvidia driver. OK. Re-enable via system settings gui. =============================== Four hours later =========================== Attempts to install Ubuntu 13 have failed. The USB installer is fine. On reboot, system locks during release of initfs. I tried different drive portsand many different bios settings. Going back to 12. :( What a waste of a day. ms@ms:~$ jockey-text --list | grep nvidia

amazing!
Copy files over as,
scp file root@192.168.1.80:/mnt/base-us/documents/
To update to include the new documents hold the power switch for a few seconds. The screen goes blank. Slide the switch again and the documents should be present.
