[SOLVED] how to invert colors in all windows

Hi. I've recently switched from lubuntu. In lubuntu I could invert the colors in all windows with customize look and feel configuration, but this does not happen in arch. Some applications don't invert their colors.
Could someone be so kind and explain me how to invert the color in all windows.

Are you using KDE, johnx? It sounds like you're using LXDE.
In KDE, I don't think you can do it automatically for all windows without writing code. But you can do it on demand for individual windows or the desktop as a whole by enabling the Invert effect in Desktop Settings > Desktop effects > All effects. Then to invert a window, you use Ctrl+Meta-U. For the whole desktop, it's Ctrl-Meta-I. I use this all the time when working in Eclipse.
Why not just use a different theme with the colors you want?

Invert colors of single window in i3

Hello!
I am using i3 WM (awesome WM! ) and wanted to invert colors. In this forum I found that I can achieve it thusly:
xcalib -invert -alter
And it works great - skype (oh, how I wish i could replace that buggy and annoying thing with something lightweight and FLOSS) and other random windows are now nice and dark but as I already have the standard gray on black terminal and a dark colorscheme for gvim they both are now too bright. Therefore I could really use a way to invert colors only for specific windows and leave the rest of my system, that is already configured dark, alone. Similarly to the Mod4+N feature in Compiz.
Some applications offer the option to invert colors for their windows but not all and it would be nice to have a quick universal means for doing it.
Can you please point me to a possible solution?
Thank you and sorry for my broken English!

Compositing would be required in order to negate the colors of individual windows. As xcompmgr does not support doing this, I think your only option would be compiz.
However, there is a program that I found a while ago called xcalib (in the AUR) that allows you to negate the colors of your entire display with this command:
xcalib -i -a
There may be a way to do this with the standard X tools, but I'm not aware of it.

How to get names of all Windows in a Form Application at runtime

Dear All,
I want to get the name of all windows in a form module programatically at run time. How to get it?
Any help or comments will be highly appreciated.
Thanks in Advance.

Hi Francois Degrelle,
First of all thanks for the response.
What if I have no items on a content canvas? In my application, I am using content canvas to hold the Image banner and help text of the current form, having no items at all. I am also using tab canvases to hold all items of form. The tabs are displayed on the content canvas at run time. So the tab canvases acts like frames (In my case).
Now if I am looping through items, it gives me the list of all of the tab canvases. Whereas the tab canvas always has no window assigned, as it is displayed on content canvas which has that Window which I need. Thus I am unable to get the names of windows in my case through the above stated procedure.
Another option could be if I can get the name of the content canvas upon which the given tab canvas is displayed?
Any way to do this or some other way to achieve the use case?
Any help will be highly appreciated.
Thanks in advance

How can I automatically "retract" all windows from my Thunderbolt display back to my MacBook Air when I disconnect the display, esp if the Thunderbolt is the desktop with the white menu bar?

I am in and out of my office with my MacBook Air. I would like to set it up so when I plug in my Thunderbolt display in the office, the Thunderbolt display has my desktop, menu bar and the open windows. If I set the Thunderbolt display to mirror by MacBook Air it adjusts to the lower resolution of the MacBook Air, which is a waste of a cool monitor. I can set it up as an extended desktop and drag the white menu bar to the Thunderbolt display so it displays my desktop but if I then disconnect my MacBook Air, the menu bar is absent and all the windows that were seen on that display are absent, as if it I was still attached to the larger display. The only way around this is to go to Thunderbolt display preferences, drag the white menu bar back to the smaller display and manually drag all windows to the smaller display before disconnecting. Doing this multiple times per day is a real pain. Is there a way to set my MacBook Air to recognize when it is attached to the Thunderbolt display and automatically my desktop and all open windows to it and then do the same process in reverse when I unhook it?

It's definitely not supposed to work like that...when you plug the display in, it should just turn on and adjust your displays. It works like that on my MBP. Kind of a silly question, but do you have the MagSafe from the display plugged in your MBAir too? Thats a requirement. Beyond that, it should "just work."
Not sure if there is some setting to enable...i haven't seen it. Call to support?

[SOLVED] How to install themes in awesome window manager?

Hello world!
I am trying to customize my awesome (literally and figuratively) system, and I keep breaking my rc.lua (luckily I keep backups). The theme I'm trying to install is Darklooks. Following the directions in This Article: http://solitudo.net/software/awesome/themes/
I cloned the themes repository and copied Darklooks to my ~/.config/awesome/themes folder, then following the advice of the arch wiki, I changed a line in my rc.lua from
beautiful.init("/usr/share/awesome/themes/default/theme.lua")
to
beautiful.init(awful.util.getdir("config") .. "/themes/Darklooks/theme.lua")
Unfortunately, when I restart awesome, I get a ton of errors, to where I'm having trouble picking out any of them to read, but everything that is normally colored is black, like it's missing a color value.
Any thoughts, hints, suggestions, or solutions would be much appreciated.
On another note: This is somewhat related, but I'm not really sure if this belongs in another thread, so If I need to edit this out and start a new thread, please tell me:
What exactly will the theme change? I know it will change the panel colors and such, but will it also change icons or do I install other icons separately? Also, If I were to add an icon theme, would that affect the indicators I have on the panel? For example, I have wicd-gtk and a battery monitor (I think it's batterymon?) that start with awesome and display on the panel, but the icons for those on the panel are pretty ugly. Is that something that would be changed by adding an icon pack, or is how they appear determined by the application itself?
Once again, I appreciate any and all solutions, opinions, etc.

Chances are that the theme you want to use has not been updated to work with the latest version of awesome.
Remember ever version change in awesome comes with code changes that require you to re-edit/write your rc.lua, I would see if you can find an email address for the author & contact him/her directly to see if it is compatible.

How do I guarantee that all windows in Safari start merged rather than spawning a new window? I know how to "merge windows" but want the default to be tabs inside Safari. Please help. Thx ... EZ.

[SOLVED]How to get colorful output when pipe yaourt's STDIO to less?

Hello, second post to NC.
My question is how to get a piped(e.g. pipe yaourt's STDOUT to less) program's colorful output on screen without such option like '--color=always'.
Before post this, I've configured less's default behaviour in "~/.zshrc" with following
less() {
env LESS=R less "$@"
And When I run:
$ dmesg --color=always | less
Everything works fine(I get good, colorful output), but when I run this:
$ yaourt -Qe --date | less
Seems that I can only get grey output on terminal emulator (without 'less' I get colorful output).
Does anyone has idea about getting yaourt's colorful output with 'less' ?
Last edited by izmntuk (2014-06-08 00:15:15)

Thanks for reply and after serveral mintues googling & getting some help from IRC:
It seems that there're some utilities that do not provide such a option like 'color=always', what we need to do is trick these utilities into thinking their's STDIO is to a tty, not a pipe.
1. stdoutisatty way (aur/stdoutisatty-git is needed) from [0]:
$ stdoutisatty yaourt -Qe --date | less
2. socat way (extra/socat is needed, sometimes doesn't work fine) from [1]:
$ socat EXEC:"yaourt -Qe --date",pty STDIO | less
3. script way (sometimes doesn't work fine) from [2]:
$ script -fqc 'yaourt -Qe --date' | less
4. unbuffer way (extra/expect is needed) from [3]:
$ unbuffer yaourt -Qe --date | less
5. zpty way (extra/zsh is needed) slightly modified from [4]:
zmodload zsh/zpty
autoload colors && colors
pty() {
local VERSION=0.2
if [[ -t 0 && $# -ne 0 && ${1} != '--help' ]];then
zpty pty-${UID} ${1+"$@"}
## when piping function pty to a pager, it may be a good idea to disable ^C *in this function*. assume that you're going to run this command: pty ls -alRi --color | less
## and now you enter a pager, and you press the End key by accident, and the pager seems stuck, and to get unstuck you pressed ^C, then the entire function interrupted. so to avoid the interrupt:
if [[ ! -t 1 ]];then
setopt local_traps
trap '' INT
zpty -r pty-${UID}
else
zpty -r pty-${UID}
fi
zpty -d pty-${UID}

[solved] How to remove color from yaourt output?

Hi everyone,
I am having a problem with removing color output from yaourt.
In order to get a list of installed packages in kdemod-core, I execute the following:
yaourt -Qs ^kdemod | grep kdemod-core | awk '{print $1}' > kdefiles.txt
Some time ago colored output was usually lost when piping commands. For some reason it is not removed anymore so that I get the following file content:
[1;35mkdemod-core/[0m[0m[1mkdemod-kde-common
[...] and so on
Of course pacman doesn't understand this anymore:
pacman -S `cat kdefiles.txt`
Btw. The same options (-Qs ) with pacman search only locally installed packages.
Any ideas?
Thanks,
David

pacman -Ss searches on-line.
Thanks, but then I don't have the packages that are installed. It is of course much faster and without color but doesn't solve my problem.
Then only thing I could find so far was a statement, that piping through less for example removes color for security reasons. That doesn't seem to be true any more.
There is a col command which outputs plain text but there are still characters left.

[SOLVED]how to connect remotely to a windows machine

hello all,
I've tried both rdesktop and tsclient but both of them will log out the computer im trying to remotely control and thats not exactly want. You know just like dellconnect does with its clients and lets them see what the fuck is happening. Both rdesktop and tsclient will only leave the client computer all logged out without any clue to whats happening. Is there any other software that can achieve this kind of behavior?

An applescript to change the background color for all finder windows

I'll start off by telling you what I am trying to achieve, then show you what I've tried.
I have a macbook with several HDD's attached. what I want is for each of those hdd to have a specific finder window background color. so no matter where I am in that hdd the background color will always be the same. so for instance if I set the background color of hdd 2 to blue then as long as I see a blue background I know that I'm within hdd 2.
I've tried setting up an applescript to do this but can only get it to change the open finder window, and none of the subfolders have their backgrounds changed.
here is what I have so far:
tell application "Finder"
tell the icon view options of the front Finder window
set the background color to {52942, 54484, 31097}
end tell
end tell
so how do I get this to apply to all subfolders without opening each one and running the script.
thanks in advance for any and all help with this

According to this article:
http://docs.info.apple.com/article.html?path=AppleScript/2.1/en/as2039.html
it seems that the various options can only be set while the window is open and in icon view.
Rather than manually opening the window of every single folder on the hard drive, it should be possible to write a script to open every folder in sequence, make sure it is in icon view, change its background, then close its window. I have never been any good at the "actions within actions" procedure needed for folders within folders, so maybe someone else with the necessary knowledge and experience might be able to assist in this regard. Such a script would probably take a few minutes to complete while it ran through "every folder of every folder", but it sure would be quicker to have the process automated than to do it by hand - computers are really good at repetitive tasks (as long as the instructions are accurate, of course!).
On the other hand, you might like to try the following:
open a few windows in icon view, choose Show View Options in the View menu (I'm in System 10.4), click the radio button All Windows, click the Color radio button under Background, then choose your color. It might achieve what you are trying to do.

Windows Vista 64 bit and HP 2840 Color LaserJet All-In-One - Workaround

Although HP has not provided a workable solution for a use of a HP 2840 Color LaserJet All-In-One with Windows Vista 64 bit, I did manage to get it to work. The solution is a bit convoluted and may not work for all users but here’s how I did it. I'm running Vista Ultimate 64 bit. Not sure how other Vista versions may behave.
I tried many different solutions that did not work. Attempting to install many different versions of the HP 2840 software in different compatibility modes ended up rendering my other HP 4385 All-In-One inoperative. I deleted every piece of HP software and hardware from my system and reinstalling the HP 4385 software. Still couldn’t get my 4385 working again. I finally ended up restoring my system to restore point prior to attempting to install the HP 2840. All this to say that if you’ve made several attempts to get it working you may need to back up and punt with a restore.
Make sure your HP 2840 is NOT connected.
Press the “Scan” button on the 2840 (The control panel on the 2840 should say ‘Waiting on PC”).
Plug the HP 2840 in via a USB cable. A “New hardware” message should pop up on the PC.
Minimize this window. DO NOT MAKE ANY ATTEMPT TO INSTALL DRIVERS. Just ignore this message for the moment.
In Windows, go to CONTROL PANEL/SCANNERS AND CAMERAS. Hopefully you’ll see a “HP 2840 LaserJet Scanner”. If not, the rest will probably not work.
Now hit the "Windows Start" button. Select "Programs" or "All Programs" (depending on your setup configuration). Open "Windows Fax Scan". It should connect to the 2840 Scanner. Experiment with the scanner and select flatbed and feeder input to make sure it functions properly. Once satisfied that the scanner is working properly you can configure the printer.
On the “New Hardware Detected” window that you minimized in step 4, select “Do Not Ask Me Again For This Hardware”.
Connect the 2840 to your network via a CAT cable.
On your PC press the "Windows Start" button and select “Settings and Printers”.
Select “Add a Printer”.
Select “Add a Network Printer”.
Windows will scan your network searching for printers. It should find your 2840.
Select “Next” (It is not necessary to let the search complete once your 2840 has been identified).
From the dropdown list, select ‘HP” and “HP Universal Printing PCL 6". It was the last one in the list for me.
Print a test page
You should now have a HP 2840 network printer and a local 2840 scanner.
O course the drawback is that you can only scan to the PC where the 2840 scanner is attached via the USB cable. You can print from any PC on your network by following steps 9 through 15 on each network PC.
Another little tidbit I ran into; selecting any other driver besides the “HP Universal Printing PCL 6" driver cause my Microsoft Office 2007 to crash any time I selected the "Save As" option. I found some links on the Internet that indicate this is a known problem. It may not affect you but you might want to play it safe.
Hope this helps someone.

Uninstall the HP software using the uninistaller in the HP folder.
Restart your PC.
Get the latest software for your printer from the "Support & Drivers" link at the top of this page.
Say thanks by clicking "Kudos" "thumbs up" in the post that helped you.

How do I change the default window color?

Having white screens is too bright for my eyes!! I always change the default window color in Windows (hiss hiss) to a light shade of gray and that setting carries thru to all windows (i.e. Word, Excel, notepad....). Is it possible to do a similar thing with Tiger? I see that I can choose between a couple of "schemes" from a "Desktop and Dashboard Settings" area (or similar - i don't have my mac here now so can't look to see the proper name) but I see no way to alter colors within those schemes. If you can tell me how to change the default color for my windows I will be awfully happy. thanks.

Personally, I wouldn't trust it, and I don't hesitate to try these things most of the time even though they sometimes cause problems. But I've used Unsanity products before and they all require installing a preference pane called APE; Application Enhancement module, and that thing caused me lots of problems for my system, lots of crashes and flakiness. I won't use it again.
But I'm sure there are lots of people using it happily, but if you don't feel confident in dealing with system problems stay away from anything that adds a system preference pane or goes up in the top menu bar at the top (Apple icons excepted) or has to start up with the system.
