Okay. I'm pretty stuck on this one. If anybody can take a look at this and advise me I'd
really appreciate it.
What happened is I did an upgrade from Xubuntu 15.10 to Xubuntu 16.04LTS. It went as expected until I got to the 'reboot' point. I clicked on the reboot button and the computer started to reboot but then it didn't come back up the way it normally does. The screen had no input signal and did the power shut down thing. I thought the computer was off (it wasn't) so I hit the power button, which of course did nothing. I left the computer alone and in about a half hour the computer came on and was fully functional.
I noticed a warning icon (you can kind of see it in the attachment--it's a red ball with a white line thru it) in the toolbar and clicked on it. (see screenshot attached). I clicked on 'Start Package Manager' and it opened the Synaptic Package Manager but it gave no instructions, so I didn't know what to do.
The next morning I turned on the computer and there was a software update (saying 'distro info data') waiting, so I ran it. And whether it was before or after the update I don't know, but the warning icon in the toolbar was gone, so I thought the update might have fixed the problem, but it didn't.
When I start the computer now it starts like it's going to work normally but the screen stays blank and I get 'no input signal' on the monitor. But in a half hour or so the computer is on properly and it works fine.
I have Googled around (I have 'aptitude' installed.) and am tempted to try:
Code:
sudo apt-get update
or
Code:
sudo apt-get upgrade
or
Code:
sudo aptitude update
or
Code:
sudo aptitude safe-upgrade
but I'm just guessing. (And I don't want to screw things up as this is my main work computer.) Any ideas? Thanks.
