Well, I don't know what is happen, but it seems to be resolved...not completely, look forward.
What I have done: I have started aptitude in GUI mode, not by command line and I have taken a look what was broken or something in standby. There was some library (from VLC media player) that aptitude told me that have to be deleted. I did it and the system start to upgrade for one hour.
After finish I watched on the aptitude log to see what it had done during the upgrading, but while clicking on the aptitude.log file the system take me out and one black screen with some rows appear to me.
What is happen I don't know.
Right now I am out of debian, but after restarting I have got one screen with many message that I am not able to understand.
At the end I find this message screen I can read:
Wellcome to emergency mode! After logging in, type "journalctl -xb" to view system log....
Well I have tryed to see, but I don't understand nothing!
During the the boot I have seen that there is one control on some device like this:
well, the question now is quite different from the initial 3D, but everything happened from what aptitude have done (maybe better from what I have permitted to aptitude to do
So I have some questions:
1) How can I see this system.log file to analyze it?
2) I don't know if the usb ports are recognized, but can I send the system.log file to one usb port, if recognized?
2) I have 2 OS (Debian & WinXp) in the same disk and Grub is the boot manager, if I wish reinstall another one system does grub will be overwritten?
Than you for your patience to read me.
