I have upgraded my Laptop from Ubuntu 11.04 to 11.10, but cannot now use my Lexmark X2650 printer/scanner. I tried reinstalling the Lexmark driver for "2600 series" models for deb systems.
When installing it all goes OK until it asks my to connect the USB cable, the Laptop freezes the install program and goes into some "Auto Install Printer" routine but cannot complete because it doesn't have the driver!!
The Lexmark install routine cannot complete because it hasn't seen the printer cable connection though the "Auto Install" one sees it, identifying the model and offering a Test Print which fails if the connection is made but this fails as the driver isn't present!
Can anyone help as this printer works OK (I have a dual boot legacy Windows Vista on the same laptop that can print OK) and it was working in Ubuntu 11.04 and it's predecessors since 9.10?

Did you try to uninstall the printer first ?(You should find the procedure on your manifacturer's page)

That is the problem, I assumed it would stay installed when I upgraded like the other settings, it didn't and no printer was shown as installed so I downloaded the zipped file from Lexmark again (in case there had been an update from the original) and tried to install it fresh. The process went as expected until I was asked to connect the printer USB lead and the apparent "Auto Install Printer" took the insertion over, locking out the running installer software. The "Installing Lexmark X2600 series printer" flag appeared but the Lexmark software stalled unable to complete. The Printer icon on the "printers" display identified it correctly but investigating the properties (there being a red exclamation mark over the icon) it shows a "cups-insecure-filter" problem and something about "Policies ,Not published see sever settings" that I can't understand.
I have no way of sorting this out and need some guidance please.

Sorry, I didn't understand you tried a FRESH install ...
and obvoiusly you installed everything as super user, not just the normal one ...

Yes that is right I did do a complete re-install and recovered my working data/files from my backup, attempting to install the printer as a new printer having downloaded a new copy of the zipped package from Lexmark for the printer. This was after an attempt to reinstall just the printer that was no longer working following the on-line upgrade to Ubuntu 11.10 from 11.04, I downloaded the ISO for 11.10 32bit from the Ubuntu downloads site and created a new "installer USB stick" on my Desktop (that is running the 64bit version).
I have not been able to use the printer with the Laptop using Ubuntu but it works normally with Windows Vista so I know there isn't any connection problem from the Laptop to the printer, it must be in the Ubuntu software.

Mmm ... are you saying you installed a 32bit upgrade on top of a 64bit operating system ?
Or maybe you are missing some 32bit libraries that make your printer work

Have you tried this ?

No my desktop computer is 64 bit, the laptop I'm using is a 32 bit installation. The problem seems to be the detection of the insertion of the USB cable from the printer is detected by the operating system and overrides (basically hijacks) the insertion and locks out the installer software that is watching for the insertion and causing it to stall. I have been in contact with someone else with the same problem. This didn't cause a problem with the previous version of Ubuntu 11.04 and it's predecessors, running the same driver install software worked then.

Sorry, but I can't think of anything else.

Hope someone else can help !!!
