Based on the information below, do you think I will experience the same stability issues witih openSUSE as with Ubuntu? (I know I’ll probably just have to install openSUSE and find out for myself).
Here’s my problem, copied from my unanswered thread on ubuntuforums.org.
I have two problems with Ubuntu 8.04, which may be unrelated to each other. I’m running an emachine t5234 with an AMD Athlon 64x2 4200+ processor and 2 gigs of RAM.
Printing ties up a lot of the CPU and sometimes freezes the system to the extent that CTRL+ALT+BACKSPACE and REISUB won’t free it up. I have turned off Advanced Desktop Affects and this is still happening.
I don’t have the syslog from a random shutdown in front of me, but I have looked at it in the past and there were no error messages of any sort from those times. Temperature is between 90 and 115 degrees. Temperature-related auto shutdown isn’t even enable in the BIOS. I have replaced the power supply.
I tried replacing powernowd with cpudyn last night for the heck of it. Don’t know if this will do any good at all.
Oh no… in my opinion, ubuntu is a garbage. I was forced to use it for 3 months here on work, and yesterday finally got my hands untied to install openSUSE.
At home, all two of my putters runs suse and no problem whatsoever.
That is a really offensive thing to say. In a world where Linux is just struggling to get a foothold, the last thing the community needs is infighting and bashing amongst distros. Most importantly, I highly doubt that Ubuntu customizations have anything to do with the posters problem at all. Keep in mind, neither Ubuntu nor Suse projects write print drivers. Thus, assuming one distribution or another will make a difference here is probably unrealistic.
MTod, you don’t provide enough info here to help you debug. It looks to me that you are trying to print over an HP Jet direct port. If so, that works flawlessly in Hardy as long as you use the “hplip” package. Please provide:
printer make and model
Method of printing (usb, jetdirect, networked cups, etc)
From the look of your log file, it seems you are having a driver issue. Here is what I would suggest trying:
System/Administration/Priting
Delete any printers installed
sudo apt-get install hplip (This is the hp driver module that works very well with your printer series.
During installation of HPLIP, it may prompt you to install your device. If not, then System/Preferences/HPLIP Toolbox, then Device/Setup New Device.
Follow the above instructions works for 99% of hp printers connected directly to the computer or via JetDirect (the network connectivity for some HP printers). In fact, my mom runs a HP 960 on Hardy with HPLIP.
If that does not work, then I need to see your kernel ring buffer (my mistake on the command, it is:
> sudo dmesg | tail -n 100
If the above does not work for some reason, then I would guess the issue is a misidentification of your serial port type. I don’t recall off the top of my head, but I think your printer requires either ECP or EPP parallel port. IF you have configured as one type in the bios, but not the other, it will not work. Hence, check your parallel port setup and try the other value. Some Bioses have support for both EPP and ECP at once.
If that STILL does not fix your problem, then it is is time to post your issue to Launchpad, not the user forum. A quick search found a few similar issues:
Wow…I should have checked this first, but your printer model is not supported with hplip using a parallel port at all. However, it is supported via USB.
If HP itself does not have a Linux driver for your printer over a parallel port, then that explains why you have had such a tough time. Come to think of it, my mom uses a USB cable on her printer.
My guess is that ubuntu found the closest PPD file out there that emulates you printer. However, there is just not that much effor put into PPDs when HP provides such fantastic support of the Linux community. For example, HPLIP provides full functionality for status of ink levels, error codes, etc. (Yes, I worked for HP for 10 years and participated in OSS).
Hey, on the plus side, this also proves that this is not a distribution issue. While I love OpenSuse, it would not resolve this issue.
Please try the USB cable and let us know how that goes.
Cool. Thank you very much. God knows where the USB cable is. I will try to track one down at Best Buy.
Since you solved one problem, would you like to hazard a guess as to my mystery shutdowns? Like I said, I don’t have any logs available from those times the machine shut down, but there were no obvious “error,” “unable to,” or “device not found” messages. And the machine is running fairly cool.
If those figures are in degrees Fahrenheit, ignore this post.
If the temperatures are in Celsius, your CPU seems to be running very hot, which happens if the heatsink isn’t fitted properly or the CPu fan has stopped. I would expect stability problems under high CPU load in such situations.
I seem to have a similar problem with printer adressing in
SUSE 11.0:
parport0 polls for /dev/lp0 but doen’t manage, I suppose:
System reports: ppdev0: claim the port first.
What happened before I got up to this point:
/dev/lp0 could be reached directly.
But only until I asked the system to find all hardware.
A printer was not found.
After that, /dev/lp0 could not be reached directly anymore.
I startet the system again and added the printer manually.
After that, the printer was adressed via cups
A pdf-page was sent to the printer, which was blinking.
But no page was printed.
Instead the system reported the above mentioned:
ppdev0: claim the port first.
All necessary options in the BIOS EC. and E… are given.
The hardware is working properly on SUSE 9.3
So sorry that I offended some people here. As I said my opinion, it doesn’t necessarely mean that things are like this.
There are so many distros to choose.
For me, ubuntu does not work, I do not like it, and I really think what I said.
Just repeating again, it’s my own personal opinion and I am entitled to it.
It’s like a taste: someone likes brocolis, someone wants to throw up…

Here in my system, ubuntu is a little better than opensuse. But I like
Opensuse too. In my opinion the better Linux for beginner user
