2010/11/2 CJoeB colleen.bea...@gmail.com: Hi, Before someone asks Haven't you posted this before?, I'll respond, Sort of, but not really! Anyway, I've reread all the previous posts. Mostly, they were related to the printer portion of the device. The printer works fine. The current problem is related to the scanner. My previous post was about not being able to use xsane as a normal user, it would only work as root. Since posting that, I've done upgrades to my system and for months, the scanner won't work at all - not as a normal user nor as root. I've tried reinstalling sane-backends and xsane using an unstable version, but that didn't help the situation. I've checked the kernel configuration and that looks fine. When installing sane-backends, after the normal USE=, there is a statement SANE-BACKENDS= ... where a number of devices are listed, but none in the 4700 series. I have no idea what is going on here. I don't scan much, but tonight when I desperately needed to scan I couldn't despite my best efforts. BTW, I AM in the scanner group, so that is not the issue. Whenever, I try to run xsane as a normal user or root, I get the message No device found. Help would be appreciated. The sane project has a pretty good search engine [1] where you can find the needed driver.

[gentoo-user] CFLAGS
Hello all, Possible noob question. I have installed a 64 bit gentoo on my intel Pentium D machine. Now I am reading through /usr/share/portage/config/make.conf.example My CFLAGS on that machine is the default currently: CFLAGS=-O2 -pipe But according to http://www.gentoo.org/doc/en/gentoo-amd64-faq.xml#cflags I can make it: -O2 -march=core2 -pipe Is this entirely necessary? Will it cause a big improvement? If I do change, how do I recompile everything? (like --newuse for USE changes?) Thank you, Coert Waagmeester

I can convert it to CVS manually simply enough. I found git has a cvsimport command, but it complained that cvs didn't recognize the server command, and some hints I saw of requiring cvs 2 made me pause ... all I can see is cvs 1.12. Vague fuzzy old memories make me think there was a cvs 2, but I see nothing in gentoo for it. I am not excited at git expecting a cvs server; I'll be danged if I'm going to muck around with that just to convert a few files when git has direct access to the ,v files themselves.

[gentoo-user] Search for a file that is not installed in the system?

installed in the system?
For example:

$ eix -I zziplib

from files archived in a single zip file

I would like equery return the same output when zziplib is not installed.
Is it possible?

Well, this is not something you install but you can use this site to
look for files that some unknown package provides.
http://www.portagefilelist.de/index.php/Special:PFLQuery2
Just type in the name and see what package it shows providing that file.
If you can, install app-portage/pfl and you can help build the list of
files as well. I run mine every few weeks or when I install something new.
Hope that helps.

With a meta-distribution, that's not quite possible to do in a definitive way. With a binarydistribution like Fedora or Ubuntu, you know what files are going to be installed by any given package, since the files are already there inside the package file. With a distro like Gentoo, the files aren't there -- only the instructions for building them are present, and you don't really know exactly what files are going to get installed until after you've built the package from the source code. If you can find a system that already has the package installed with all of the USE flags enable, then you can look at that system and be pretty confident that the same files would be installed on your system should you install that program with the same USE flags. So if you install all packages with all USE flags set, you can then search that system to find out who owns a particular file. Somebody's already posted a link to a site that attempts to do something like that, but there's always the possibility that your USE flags will cause a slightly different set of files to be installed (IOW you may already have the package installed, but you don't have the required USE flag). -- Grant Edwards grant.b.edwardsYow!

How did this happen? The man in charge three managers ago thought this was a cool way to configure critical servers. Because One filesystem mounted at / was option #1 on the disk page of the SLES install wizard. Thanks, I'm relieved to know that I'm not cut from managerial cloth :) I'm assuming that SUSE releases security patches from time to time. How do you keep all those machines up to date if you can't take them offline? Maintenance time slots. A reboot after installing a new kernel takes less than 5 minutes and nothing else really requires a reboot, so this passes the Change Management process easily. Other updates are usually a service restart which can be done on the fly. So never take offline doesn't actually mean *never*, it means outside agreed service levels Fixing / means take the machine offline for X hours where $X is some large number depending on how big / is and how fast tar runs. And the Change Manager asks his usual horrible questions: What's the risk? What's the impact? Is this customer facing? Does this problem reduce quality of service to customers? Don't you have Nagios to manage exactly this kind of thing? His answer to my answers is usually something like You're kidding me right? This is another one of Alan's pranks, right? -- alan dot mckinnon at gmail dot com

Hi,
The current problem is related to the scanner. My previous post was
about not being able to use xsane as a normal user, it would only work
as root. Since posting that, I've done upgrades to my system and for
months, the scanner won't work at all - not as a normal user nor as root.
The sane project has a pretty good search engine [1] where you can
find the needed driver.
Hint: Try hpaio :) PS: Your internet search engine of choice is your friend.

Thanks for the link. I got the scanner working and BTW, I did do a
google search, but the search parameters I used only returned stuff from
my previous posts.
The reason for the Att'n Neil Bothwick in the subject line is because
Neil responded months ago when I had the scanner working the first time,
but could only run xsane as root, not as a normal user. Neil responded
suggesting that I write a udev rule and gave me an example:
SYSFS{product}==CanoScan, SYSFS{manufacturer}==Canon,
GROUP:=scanner, MODE:=0660
I used this to write a udev rule after reading some documentation. Of
course I changed the product and manufacturer in the above line to what
is applicable to my HP C4795. After rebooting, I was able to run xsane
as a normal user. However, when I run it from the command line, a bunch
of messages appear and I'm not sure if there is a problem or if I didn't
write the rule correctly.
This is the message that repeats itself in the terminal window:
(xsane:10566): Gtk-WARNING **: GtkSpinButton: setting an adjustment with
non-zero page size is deprecated
Do I need to be concerned about this?
Regards,
Colleen
