When I tried to un-install HAL using Yast2, it gave me a list of conflicts as long as my arm. I tried using the installation disk's repair facility to un-install HAL but all it does is checks the base packages to see if anything is missing.

Below is a sample of the conflicts from Yast2 when I attempted to un-install HAL.

By the way, I installed Smart and it is easier to use but it also wants to un-install scores of programs along with HAL.
Is there a way to un-install HAL without un-installing many other related packages?

Thanks for your time and patience,
Roy

The hal package is basic for the system operation, so you need to either --force it if using the rpm command, or update it in YaST (update will reinstall it without breaking dependencies).

I Threw In The Towel

Hello auxsvr, ngjunkie0011, and RHAPOLLO,

Thank you all for your help. You all are an asset to the Linux community.

But I threw in the towel and re-formated the openSUSE partition and performed a clean install and this time around I will not install that hpoj printer driver just to be on the safe side. I'll take your advise and use the hplip driver instead. The reason I used the hpoj driver in the first place is because I was having a hard time getting the scanner portion of my multi-function device to work.

But I now have openSUSE about the way it was before I had trouble with it. I didn't lose much data except for a few emails and a few bookmarks. Plus now I can access all of my USB devices without trouble.

Keep up the good work,
Roy

What is the device you have the problem with?

Hello,

I was having problems getting the hplip driver to detect the scanner of my HP G55 multi-function device connected to the parallel port.

But according to the paragraph below, the hplip driver does not support scanning using this multi-function device if it is connected to the parallel port.

Code:











"The previous HP scanner driver "hpoj" for HP all-in-one devices is still available. This driver requires the "ptal" service; see SDB:Set up a HP OfficeJet ("all-in-one" device). The ptal and hplip services are mutually exclusive, as ptal occupies the device for itself, thereby preventing hplip from accessing the device. On the other hand, HPLIP does not yet support devices connected to the parallel port. Accordingly, if you have an HP all-in-one device which cannot be connected to the USB port, the scanner driver hpoj with the ptal services must be used for all HP all-in-one devices. Despite this limitation, it is better to make HPLIP available to a wide user base at this stage (0.x version), instead of waiting until support for non-USB devices is implemented.

No wonder I was having a hard time getting it to work.

Roy

In that case, the only option is to install the hpoj driver or use the USB interface of the device. The hpoj driver is going to need some tweaking to function properly, if possible at all, so I don't know whether it's worth the time.

I didn't mean to discourage you from making the hpoj driver work, what do you intend to do?

This Time No Problems

Hello auxsvr,

I have been tweaking my other Linux distributions since I last posted on the hpoj printer/scanner driver in this thread. I decided to give it a rest.

So I decided to boot back into openSUSE and I installed the same hpoj driver that I had when my external USB hard drives stopped working. But this time, the USB hard drives were not effected. I can still access the drives with no problem. Plus, now I have printing and scanning capabilities with this hpoj driver.

So now I don't have a clue as to what caused my external USB hard drives to stop working. As I posted earlier in this thread, I performed a clean install to fix them.

You asked me earlier if I would consider using the USB port on my HP multi-function device and use the hplip driver instead. I would love to use the USB port but I suspect the USB port on my device does not work. I lost all printing and scanning capabilities in each one of my Linux distributions, including Windows XP. That is why I had to switch to the parallel port. I really can't tell it is that much slower either.

But thank you for your willingness to help in the event that I might encounter more problems with installing the hpoj printer/scanner driver.

All the best,
Roy
