I successfully installed Guake on CentOS using the guide found here:
http://ww.centos.org/modules/newbb/viewtopic.php?viewmode=threaded&order=ASC&topic_id=33556&forum=56&move=next&topic_time=1317663060
I've added as the last item on my startup applications list to ensure that everything loads including drivers and other daemons before Guake starts. The only problem I'm having is that Guake window can't make its background transparent.
It there anything I can do to fix the transparency problem?
This should go to superuser.com, not StackOverflow.com but I'll answer anyway: Righ click on the open guake window, select preferences, then select the Appearance tab,and at the bottom in Effects there is a slide control which lets you select the transparency level.
Any admin out there can move this question any minute, and some more overzealous user can down voted. By replying I can be down voted :-)

I work in an environment where we have to have a security classification banner displayed at the top of each monitor on our Gnome Desktops. Currently, I am using a Perl/Tk window to display the classification of the system. However, that window cannot be moved because of the way it is built (no decorations) and occasionally overlays open windows making it difficult for users to manage those windows.
I would like to be able to do something different, but I'm not sure where to start. Three ideas I have are this:
An icon or something in the Top Bar showing the classification
A banner, like the Top Bar, that sits above the Top Bar
A window, like I already have, but relocatable
I figure the first option would be easiest, but since the Top Bar isn't shown on every monitor, that may not be the best option. I don't even know if the second option is even possible. The third option would require me to use something other than Perl/Tk but that's the only language I'm fluent in at the moment.
So I'm looking for suggestions or examples or Gnome extensions I can use to solve this problem.
Thanks.
There is a classification-banner python utility at https://github.com/fcaviggia/classification-banner. It's no longer maintained, but we've been using it without change for a few years now. It's OK. One problem is that it doesn't "shrink" the desktop screen, so application windows can overlap it; it's set to Always On Top, but it would be nicer if it actually couldn't be overlaid at all.
A simple solution, of sorts, would be to change the desktop background image. This can have issues if you're displaying on multiple resolutions (I don't know if Gnome supports SVG for such purposes) and of course it can be obscured by windows covering it.
Older versions of Gnome let you create multiple bars that worked perfectly, but that disappeared - along with many other customizations - in Gnome 3.
I am using VC++ MFC and have the following toolbars in my software.
While working with different screens and software is minimized, if we disconnect the other screen, the toolbars get messed up after restoring the application.
Also that issue occurs, sometimes, when using single screen and change screen resolution or laptop lid is closed and re-open it, most of the cases when application is minimized at time we change anything.
We are not executing any code as such to draw the toolbars every time. While software is starting up, we read the toolbar positions from registry and create toolbars, and while closing application, we read the toolbar current position and save it back to registry.
Please suggest what should I do to fix this..
Thanks...
From the details what i can say is, while you were working on screen of one size the application considering the toolbar co-ordinates in relation to that screen. But when screen changes the old co-ordinates are no more valid as new screen may have different size and that's what causing the issue.
I have on Linux/KDE a installed version of eclipse Mars.2. But there are strong problems with colors. So there is no different between a activated toolbar button and a inactive toolbar button. At example the "Link with editor" button of the "Project Explorer" view has exactly the same background color if the button is selected or not:
Another thing is that I cannot see if a checkbox or radio button is selected or not. It seems that the foreground color for the check/radio box selections is also identical to the background color. So there is in many configuration views no way to find out what's currently selected and wath's not. In the next screenshot at least one of the "Open mode" radio button must be selected (I assume it's "Double click" button):
Note also that the colors are only in eclipse wrong. In other (native) KDE applications I don't have these effects (at example the foreground of check boxes/radio buttons are black - like I have it expected). Also play around with the color settings in KDE "Application Appearance" has no effects ...
How can I change the colors of these stuff?
There is an Eclipse plugin that helps you import downloaded themes from the online marketplace (themes are free).
This is where you can find it: http://eclipsecolorthemes.org/
You may choose whatever eclipse theme fits your needs!
Good luch!
Ok. Found the solution for my problem on following site:
http://www.jroller.com/andyl/entry/mars_on_linux
Mars is the first eclipse version which uses GTK3 (instead of GTK2 like eclipse versions before 4.5). And on the side above Andrey Loskutov wrotes that may be also the GTK theme (widget style) can be also the problem. The Widget style "oxygen-gtk" should be extremly buggy! After changing the widget style (to now "Adwaida") the problems are gone :-)
You can change the Widget style in KDE by opening in the KDE settings: "Application Appearance" and "GTK+ Appearance".
I've been having this problem with the Matlab GUI (linux) that has been annoying me for over a year but I still haven't found a solution.
Basically, the autofix hints are not displayed. When I move the mouse cursor over a potential warning/suggestion, a gray-background pop-up appears but the text inside is missing. The same happens when I hover over those little warning bars on the right hand side of the editor. Does anyone have any clue what might be causing this?

This happens only on my linux machine (Ubuntu 14.04 LTS, NVidia GeForce with nvidia driver).
Thanks!
For those interested, this issue appears to be related to the Unity Desktop. Mathworks does not provide a fix but suggests using a different XServer instead. Here is the answer I received from support:
This issue is known to occur due to a windowing system used with
"linux" on which MATLAB has not been tested. It has been observed that
if you are using "Unity desktop" in "linux", then the tooltips are
displayed as blanks.
To work around this issue, you may try switching off "Unity desktop".
You can refer to the following links for more information on this
issue:
http://www.mathworks.com/matlabcentral/answers/116987-empty-tooltips-in-code-analyzer
matlab code analyzer produces empty tooltips
Indeed, I tried lubuntu and XUbuntu (Xfce) and the tooltips in Matlab were working in both cases. I find Unity very handy because I got used to it, so for now, I will probably simply not use this Matlab feature. Hopefully this will be fixed eventually.
It's an old post but some people may be still looking for a solution or a hack. Well, I also had this issue on R2015a when using two monitors and hiding Ubuntu 14.04 sidebar seems to do the trick. This link explains how to do it: http://www.howtogeek.com/198218/how-to-easily-hide-the-unity-launcher-in-ubuntu-14.04/. Hope it helps!
This is accomplished, in the article, by:-
1) Select “System Settings” from the drop-down menu.
2) The “System Settings” dialog box displays. In the “Personal”
section, click “Appearance.”
3) On the “Appearance” screen, click the “Behavior” tab.
4) On the right side of the “Behavior” tab, there’s an ON/OFF switch.
Click the switch so it reads ON.
5) The ON/OFF switch also turns orange. Additional options for how to
show the hidden Unity Launcher become available in the “Auto-hide the
Launcher” section of the “Behavior” tab. Under “Reveal location,”
select whether you want to move the mouse to any location on the “Left
side” or just to the “Top left corner” of the screen to reveal the
Unity Launcher. Use the “Reveal sensitivity” slider to change the
sensitivity of the reveal location.
6) Once you have chosen your settings, close the “Settings” dialog box
by clicking the “X” button in the upper-left corner of the dialog box.
This happens to me in Ubuntu 15.10 using xfce, with two monitors connected to an Nvidia GeForce 8600 GT, one of which is rotated to portrait orientation. The "workaround", from the page Anton linked, is to resize my matlab desktop such that the red underlined text or red scrollbar annotation is in the bottom third of my left monitor. Unbelievable.
My preferred workaround is to use Python+Scipy+Matplotlib instead of Matlab.
By mistake, the option on "custom sizing options" was set at 500% in the section "change the size of all items".
The result is all elements on the screen are huge, and whereas I am able to reach the display section and through tab I am able to navigate some options on the left panel, I am unable to reach the change the size of all items section.
I have tried several things to revert it to 100%, but all have failed so far:
Restart on safe mode. Displaying it on a different monitor and proyector using both hdmi and vga. Uninstalling the graphics driver didnt help. Using the "zoom" only has option to zoom in. Changing the screen orientation to vertical in hopes of accessing more options allowed me to see the left panel but not more. Using ctrl + mouse doesnt change the size inside the Display section. The computer doesnt have a restoration point to go back to, and I cant uninstall the applications because it isnt my laptop.
I have been searching for the correct command to execute but the closest I have found is "Display Properties control desk.cpl" and it is not the command I need. By the way, the computer is a lenovo using windows 8.1 in spanish. I have tried in other computers, for example a dell in windows 8 and the percetage is limited to 200%, so I cant test it correctly.
If somebody has a solution or any suggestion please share.
