Can't see screen after updating to CUPS Jessie

Can't see screen after updating to CUPS Jessie

Hi Guys! Happy New Year!
I was happily using my amazing Point Linux 2.3.1 (Wheezy) and I needed to add a the HP LaserJet P1100w at the office to try it out.
Well, it appears the python-cups needed to be updated to use this printer. Soooooo, I went into Synaptics and did the update.
However, the latest python-cups needed the latest CUPS which meant using the version in Jessie so I updated Synaptic to use the Debian Jessie sources.
Anyhow, after about 300 MB of updates, I restarted and all I can see is a dark screen with 3 little tiny squares. LOL!

I can get to the command prompt but I don't know what to do.
I'm so annoyed for adding the Jessie sources just so I can get the latest CUPS for that stupid laser printer. :%)
Can ANYONE suggest how I can get back home?? :unknown:
I really want my desktop back. What do I need to do at the GRUB menu (2nd option) where I can log in as root in the text screen??
Oh well, I have learnt my lesson.

If I have to reinstall, no biggie. What's the simplest method? I already have my hard drive partitioned as: /home, /boot, /, and something else, I forget! Oh, it's the /swap partition!

Thanks guys!!

Point Linux rocks!!

hi. experimenting is good way to learn.

there are at least to solutions. the first and trivial one is to reinstall whole the system. the second one - downgrading. I do not know if it works in your case but you can tray to define new pinning (at the moment there is one file (/etc/apt/preferences.d/50pointlinux) for defining repository order preferences. there is the present pinning (in my case, I have neither testing nor backports repositories)
Code: Select all
Package: *
Pin: release n=wheezy
Pin-Priority: 900

Package: *
Pin: release n=taya
Pin-Priority: 990


I understand your screen is black so you can use terminal. try another console with ctrl+alt+f1 key. you have both stable and testing repositories (at least). the main goal is to go back to stable. firstly be a root (use sudo su, sudo -s or sudo -i commands). you can use nano to (create and) edit preference file
Code: Select all
nano /etc/apt/preferences.d/50pointlinux

and
Code: Select all
Package: *
Pin: release n=wheezy
Pin-Priority: 900

Package: *
Pin: release n=taya
Pin-Priority: 990
 
Package: *
Pin: release a=testing
Pin-Priority: 50

ctrl+o, enter, ctrl+x. you have new pinning. taya has the highest priority, testing - the lowest. next
Code: Select all
apt-get update && apt-get upgrade

to just see the changes you can use option -s at the end.

reboot or shutdown -h now end the process.

hope it helps. cheers,
ride my bike,
