[gentoo-user] Running xsane

[gentoo-user] Running xsane

[CJoeB]

Hi everyone,

I have purchased an HP C4795 Photosmart All-in-One printer, scanner and
copier.  I have gotten the printer to work fine after installing the
unstable version of hplip.  The copy mechanism works also.  However, I
am having trouble with the scanner.  I again have installed unstable
versions (i.e. ~x86) versions of sane-backends and xsane).  If I run
xsane as root, the scanner is recognized.  However, if I run xsane as a
normal user, the device is not recognized.  I can't seem to figure out
what to change to rectify this - I've tried changing the owner and group
on the xsane executable, but this didn't work.  The permissions for the
xsane executable seem fine.  I have added myself to the "scanner" group,
but this doesn't seem to have any affect.  Also, despite the fact that
the device can be set up wirelessly, I have not done this - I have the
unit connected to my computer via USB cable.

Any of you gurus have any ideas?

Regards,

Colleen

Hi Colleen,

I also have one of those All-In-One printers.
To get it to work, I added the "saned" user to the following groups:
- lp
- usb
- scanner

I'm not sure, but I think "usb" is sufficient for the scanner, but with these, 
it works on my system.

Your scanner's dev node has can only be read by root, the easiest way to
fix this is with a udev rule, as the node name changes each time you
connect the scanner. This rule works for me, I'm in the canner group,
just change the product and manufacturer strings to match

SYSFS{product}=="CanoScan", SYSFS{manufacturer}=="Canon", GROUP:="scanner", MODE:="0660"

He was wrong, understandably. He should not have included all white men 
in that set. Outside USA we have no illusions of saving time by 
adjusting our clocks.

When it comes to politicians, I'm not quite that sure. Over here
in Germany, there're lots of them who still believe in that
insane idea of messing up the clocks would bring anything but
useless hassle. I really wonder if there's some hidden lobby
which benefits from this crap or it's really just stupidity ;-O

Well daylight savings do make sense. The idea isn't as much to gain hours  
in a day, we have 24 hours in a day. The idea is for the body to follow  
the rhythm of the day. Noon is when the sun is at its highest. Depending  
on how the sun is positioned in comparison to the earth. So it makes sense  
with daylight savings, although it does mean that I go to school when it's  
dark and come home after dark.

no, for the exact reasons you wrote, daylight saving make no sense. With 
daylight savings the sun is not the highest at noon. And changing time puts a 
lot of stress on the body.

For health reasons it should be scrapped. For energy saving reasons even more 
so.

But it means you spend more of your waking hours in daylight (unless
you're a postman or milkman), which has both health and environmental
benefits. That leaves the question of the problems caused by the twice
yearly changeover, which can easily be eliminated by running an hour
ahead all year round, something that was tried in the UK some 40 years
ago and abandoned.

Of course, the whole thing of the tagline came about because of the name,
you are not saving daylight at all. In the UK, it's called Summer Time,
probably because that means we can tell when it's summer by checking the
clock settings :)

not really. If I have to get up at 4am in the morning to reach my job at 7 the 
difference at morning is negligible. And in the evening? Since I am home early, 
no difference at all.

And environmental benefits? Are you kidding? There are no energy savings with 
day light savings. More lights are used in the morning. More energy used for 
heaters. If daylight saving would reduce energy usage, it would have been 
banned decades ago.

It is called summertime in Germany too. I am living in more rural Germany - 
and the cows are not very happy about it. Neither are the farmers.

Just picking the last post.  This is what I hate about DST.  My old VCR 
was doing fine until they changed the schedule here.  Since I can't 
re-program my VCR with the new schedule, I had to disable DST thingy and 
do it manually.

I would rather see this stupid thing gone.  It doesn't make the grass 
grow any greener plus it makes people have to run around and reset all 
the clocks and crap, not just once a year but twice a year.

The only good thing, it helps some people remember to replace the 
battery in the smoke detector.  Of course, one could come up with a 
better way of doing that too.  Most of them beep for weeks when it gets 
low, which is ironic since the beeping runs the battery down.  o_O

In our house, that's the job of my grandpa (former fire inspector).
Of course he gets reminded by his speaking watches (yes, plural!) ;-o

Then you fit into the postman and milkman exception :)

I'm in the opposite category, I'm a late riser so it suits me.

The move away from "standard" working hours has made this less relevant,
but still the majority see more of the daylight if the clocks are shifted
forward.

Modern "green" building make better use of natural light, so there are
benefits to having as much of the working day in daylight as possible.
But once again this is less relevant ion these days of flexible working.

What with their greenhouse gas emissions and insistence on their farmers
working at unearthly hours, those cows have a lot to answer for. When are
they going to start considering the environment?

The huge amounts of methane they emit, although it turns out we blamed
the wrong end of the cow for that.

Let's be fair about it.  Here in the US, we don't have the
illusion of saving _time_.  We have the illusion of saving
_energy_.

And just think of all of the geeks it employs everytime
somebody in DC thinks it's a good idea to futz with the
settings.  I personally know of somebody who spent a couple
weeks developing, testing, committing, and pushing out a patch
for a commercial Unix whose name I won't mention.

No, you miss the point. The name implies saving daylight, not time. Show 
me anyone who can do that. (And I won't ask why Saving has to be 
plural.)

More examples: what is the one thing that shock-absorbers don't do? What 
does a condenser (on a carburettor) condense? What heat-transfer 
mechanism does a car radiator use? (Hint: if it uses radiation, why does 
it need a fan?)

This is now way off-topic. It is fun though.

Never heard of a condenser on a carbuetor.

Google doesn't seem to know about it either.  Are you referring
to the condenser (capacitor) that's located along with the
points in the distributor assembly?

Or is it something that goes by a different name here in the US?

And "convection" ovens use a fan to circulate hot air instead
of the mechanism used by conventional ovens.  What mechanism do
conventional, "non-convection" ovens use?  You guessed it: convection.

Riddle me this as well: what good does Daylight Savings do in, e.g.,
Scandinavian region countries, which have fair sized slabs of their
landmasses on the North side of the Arctic Circle?

I mean does somebody actually think that seeing Aurora Borealis in the
dark is a proper ersatz light source over sunlight? It's dark 24 hours
a day on the worst days, with only scanty lighting on the days before
and after those. One can turn the clocks upside down or replace the
hands with a 10 000 rpm fan, and it won't squeeze any more sunlight
into the sky due to basic physics.
