A Problem With GIMP

Using kubuntu 16.04.

When trying to use GIMP, there are little text windows that
appear to identify what various symbols, and some drop down
menu items are. Unfortunately, the text, and the background
colors are so close, if not identical, that they can't be
read.

Oh, and before I forget, the kpatience solitare game will
download various card designs, but won't let you use them.

Installation Problem

On Kubuntu 16.04

Not one of the following will insatall without all the rest, but
all of them interfere with all the rest. No install, no configure,
dependency problems, can't find an un-named directory, etc.

nginx
nginx-core
nginx-full
nginx-light
nginx-extras

What gives?

Bill

xrandr question

Running Kubuntu 16.04 here.

I'm told that if you want xrandr to do a particular resolution
on boot up, you have to put the command in a file named,
".xprofile". That's nice as far as it goes, but where do I put
the file? Does it need any special treatment like:

chmod a+rwx ~/.xprofile

or whatever?

Bill

Synaptic Problem

Synaptic is giving me the same error message that apt-get is,
I.e., "W: No sandbox user '_apt' on the system, can not drop
privileges". Unfortunately, synaptic is treating it as a fatal
error, and the download dies at that point. It also has the
same, "tiny text", problem as firefox.

Anyone know how to fix these?

Bill

More 16.04 problems

While working on getting the system rebuilt, it was hemorhaging
email for about a day and a half/two days before I got it fixed,
so I lost a bunch of it. If I haven't replied to anything in the
last, couuple. that's why.

Got the teensy text problem _mostly_ fixed but not completely.
Most notably with firefox, which is a whole number of problems
all by itself. The basic version that comes, "in the box", couldn't
find it's, ".o/.o.so", files with both hands, and so, wouldn't
launch. I finally did an, "apt-get install reinstall firefox", and
got a working version of the latest firefox.

Install Problems

Ok, I'm sitting here with a brand new 16.04.2 install,
done the upgrades, and while it's a bit of a
disapointment in some ways, it does just fine in
others. Par for the course, I guess.

One of the problems is that firefox can't find its,
".o/.o.so", files with both hands.

Screen Res problem in 16.04

Ok, I'm checking out the try it and see portion of a
16.04 install DVD. When I get to the screen resolution
portion of os the System Settings, the choice of
available resolutions is completely unsatisfactory.
There are _only_ two, 720X400, and 1920X1080. I have
to use a _LARGE_ magnifying glass just to see these
numbers, and clicking on either doesn't change the
resolution, at all.

How do I get this to work, and with the entire
spectrum of resolutions to pick, and choose from,
so I can get something decent to work with?

Bill

Docs?

Are there any "HowTos"/manuals/tutorials/ebooks/etc specifically
for dealing with 16.04? Also, What about new/old Plasma issues?

Thanks in advance.

KDE Menuing Kaput

Howdy;

Did an OS re-install, (12.04), to get my sound back, and
both it, and the new kernel seem to be working ok. There
is, however, a new problem.

I installed the full KDE, educational, games, libreoffice,
the works, along with a bunch of other stuff. These
usually add a bunch of entries to the launcher menus, but
this time, virtually nothing has been added.

Is there any way to kick the, "menu adder", into proper
operation?

Bill

Sounds like a problem

Running 12.04 on an amd64 machine. I just got the latest
kernel, (3.2.0-98), and my sound disapeared. Not even the
boot up music is there anymore. Anyone know whats going on?

Bill

Session Bus Gone AWOL

Using 12.04.5.

I've had problems getting DBus working for a long time.
I think I've finally found _a_ reason why, though there
may be more than one, but here's where it just starts
getting wierd.

Merry Christmas

Merry Christmas, one and all, and a happy New Year!!!

Okular Question

Okular seems to be working fine from the desktop, but
I'm seeing some odd error messages, when used from the
terminal/shell. Here's what happens:

okular RolliesDadsMethod.pdf
okular(19719)/kdeui (kdelibs) KXMLGUIClient::~KXMLGUIClient:
0x9915d0
deleted without having been removed from the factory first.
This will leak standalone popupmenus and could lead to crashes.

Anyone know what's going on here?

Bill

Other platform support

Are there any versions of kde that will work on other
platforms, such as the, "Raspberry Pi", or the, "Beaglebone",
etc.?

Bill

Video Question

Ok, so how come I can watch and listen to some videos with
Firefox, download it, (with downloadhelper), and then watch
it, but there's no sound?

Bill

Apt-get Problem

When I try to use apt-get to update, I get dumped out with the
following error msgs. I have no idea why this is happening.
I seem to recall seeing a cure for this a while back. I think
it was a dpkg option, but I'm not finding it in the man file.
Anyone recall this, or was it another command?

Download Question

Howdy;

Since I upgraded to a 64 bit system, I've noted stuff for
both 64 bit, and amd64, and on some sites they are treated
as if they are identical, and indeed, they seem to compile
and work ok. Then there are things like gdebi that say
that amd64 is the wrong architecture, and exit.

Anybody know what the story is here?

Bill

apt-get problem

For some reason apt-get seems to think I want what I allready
have. It's giving the following error msg(s). Not only that,
but it's the 32 bit version, and I'm running a 64 bit system
now. Anybody know how I can clear this out?

Downloader Question

Howdy;

Apt-get is nice as far as it goes, but the choices
are somewhat limited compared to muon, and synaptic,
etc. Is there some way to tell muon/synaptic, et al
that you want the _source_ for a particular program
in their listing?

Bill

Upgrade Question

I'm finding 14.04 to be less and less satisfactory as I go
along. It's as if someone did a study on everything I do,
and how I do it, and then surgically removed them from the
distro.

So, my question is this: Can I upgrade to 14.04, but dump
the latest garbage and keep/re-install kde 4.8.5?

Bill

Neat Trick

If you use a file manager very much, here's a neat
trick you might find handy. Just run the following
bash snippet.

cd /home/$USER/Desktop ; Name=$(cat /etc/hostname) ; ln -s / $Name ; cd -

Now look in your Desktop window, (on your Desktop, natch).

Happy clicking.

14.04 Questions

Just got my machine back from the shop, with a
hardware upgrade, and now with 14.04 installed,
and I've got a slew of questions. I'll try and
limit them to a few at a time.

1st, what happened to the little cubes down in
the panel, the ones you click on to go to
different desktops?

2nd, What happened to being able to go to
different screen resolutions with ctrl alt plus
or minus?

Neither feature is in evidence.

Bill

Upgrade Question

Howdy;

Well, it looks like my long awaited hardware upgrade will
soon be happening, and thus an upgrade to 14.04, as well.
The question I have now, though, is this: The old box was
32 bit, and the new stuffings will be 64 bit. Is there a
way to tell the upgrade mechanism to switch to 64 bit, or
will I need to go to an install disk? No big deal either
way, but I'd rather not waste my time if the disk is
required.

Thanks in advance.

Bill

Upgrade Insanity

Howdy Folks;

Some of you may recall a while back, I had problems with
getting 14.04 installed on my machine, and that the
problem was basically an aging machine not being able to
deal with a new OS. It'll be a while yet, before I can
afford the computer upgrade, but it'll get here eventually.
I would long since have upgraded if I could, and really
don't need to have my elbow jostled.

In the mean-time, I've had to put up with moderately
annoying, continual reminders that, "There's a new OS,
click here to upgrade now!", etc.

The Slave Master Cometh.....

Howdy;

There's a program I use, and intend to keep on using. Somehow or
other, apt-get has decided that it was, "automatically installed",
is, "no longer needed", and that I should use, "apt-get autoremove",
to make it go away. How can I get this, "artificially _un_intelligent
slave master", to behave?

Bill

Apport Question

Howdy;

Anybody know what protocol/mechanism apport uses to send
it's messages? I have to manually enter user/passwd for
smtpauth, which doesn't work for apport. I want to see
if I can do a netcat wrapper or something of that sort.

Thanks in advance.

Linux tricks

I've come across a compendium, a treasure chest, a
veritable cornucopia, of Linux tricks and tips, and
so, I just have to dump it into your laps.....:-)

Package Listing

Howdy;

I'm not sure which prog might be best for this, (apt, apt-get, etc.),
or even if it can be done, but is there a command that will return a
complete listing of all the programs that have been downloaded, since
installation day one?

Bill

Kernel Compile Utils

Howdy;

Does anyone know where to find kernel compiling utils like config,
menuconfig, etc.? One used to find them in the source directories,
but *buntu doesn't seem to do that.

Bill

Util Question

Is there a util that will change the text and background
colors in a pdf file to something more readable? Plain
old black on white by preference.
