Initially I realize this isn't going to have all the information needed so one of the first things that would be good is getting advice on how to obtain the relevant debug logs or... how to actually find my terminal now.
I was previously using 12.10 fairly happily, I had some kind of repository update error which initially resulted in being unable to update anything due to (I think i remember this right) some corrupt or missing packages. After a bit of fiddling this all seemed to go away with the exception of a red
do not entersign which then hung around in my top right hand unity bar for a while. So I trundled on and happily ignored it all for about a month.
However yesterday, I went to update and something went pretty wrong. To my eye Unity seemed to crash, the launch bar disappeared, the top bar disappeared, Ctrl+Alt+T stopped working. I could bring up a new browser window using the F keys, and later discovered I could take it out of graphical mode to access some form of terminal.
This even went through to the logon screen which held a similar kind of look, but now with incorrect fonts, inconsistent transparencies and apparently highlightable text. Very odd.
I figured I'd uninstalled unity somehow, went out of graphical mode,
sudo apt-get install unity (which did in fact appear to be missing). Reinstalled it successfully but then... still won't.
My plan B was to upgrade to 13.04 (i figured this might paste over the cracks I seemed to be working so hard to develop). I managed this, rebooted but the problem persisted.
Launcher has returned now although the dash search seems unable to find the majority of installed programs. Ctrl+Alt+T is still absent (which is the most scary for me as my entire working knowledge of Linux centers around cunningly Googled terminal commands). Gnome appears to be the default choice for browser and top bar.
basically everything looks like this:
can anyone tell me
- How I might have managed this (would be nice not to do this again).
- what therefore caused it
- How to repair it
I'd prefer not to have to reinstall my system as there's files poorly organized everywhere and I'm not sure what I might be nuking.
Also all of the above reoccurs consistently no matter how many times I go about restarting...
A beautiful mess.
