Unity3D scene blank in ubuntu - unity3d

I am very new with unity3d. I download unity3d in format .deb file and install it. Is it because it missed configuration or something not support? Thank

I had a similar problem with Unity running on a Debian machine.
After spending half a day fighting it, the most simple solution worked:
I simply changed the layout, causing the scene to re-render, and changed it back.
Click on Window > Layout > 2 by 3
Than choose your favorite layout.

have you checked all your graphics drivers? this black screen can happen if it is not all updated, go to the terminal in Ubuntu and try this command - sudo apt-get install xserver-xorg-video-intel, Once you've done that click this link and try installing the new build of Unity if you haven't
http://beta.unity3d.com/download/f4fc8fd4067d/public_download.html
Hope this helps!

This is strange, I used unity3D on Ubuntu 14.04 and 16.04 and it worked fine, if I remember correctly not all versions are good (I mean unity versions and linux versions).
I've seen a similar problem on other apps that was solved by resizing the window (somehow that forced a redraw of the content that moving did not)

neovim onedark colortheme displaying wrong

I have recently downloaded neovim to start developing there, and I wanted a color theme the one dark from atom, but for some reason doesn't work properly, the whole screen comes blue, I searched in other places but I didn't see anyone with the same problem, I'm in macOS 12.5.1, I even tried to run the theme in a ubuntu machine, in a docker container and is the same problem, Has anyone had this same problem?
Here's a picture
screenshot of neovim
There's no solution I was using the default mac Terminal, it appears that the Terminal is stuck in the 1970's and doesn't process termguicolors, as a remedy.
I'm using alacritty know, and works fine know.

Netbeans 12.1 menu fonts too small, --fontsize no longer works in /etc/netbeans.conf for Ubuntu 20.04

Netbeans 12.1 no longer respects the --fontsize directive in the /etc/netbeans.conf config file.
The menu fonts are way too small on a large screen.
Yet setting Preferences->LXQt Settings->Font->Point size in the Ubuntu control menu, which is normally respected by most Unix app windows, does not carry through either.
And although Netbeans's
Tools->Options->Fonts & Colors->Profile: NetBeans->Syntax->All Languages->Default -> Font
setting changes the font for the code itself inside the editor, it doesn't change the IDE menus.
You would think, after all these years, that there would be a command inside the Options to change the menu font size, but it's still not there yet.
And now editing config to change the --fontsize startup option is no longer respected.
How best to change the size of all the system fonts in the Netbeans IDE display environment?
The best solution I've found so far is to change the Look & Feel.
Invoking aptitude install netbeans currently (Sept '20) gives version 10, which breaks with a jcraft/jsch error, also "could not successfully run the /usr/bin/g++ compiler" on my system even though g++ is perfectly fine and protections cleared, also "Build Host not connected", after C++ is installed from the 8.2 repository. Tastes like some kind of jdk error (I've got /usr/lib/jvm both 8 and 11 jdks installed, hard to believe it can't find them). But if the install doesn't work right out of the box, it's a bad sign. So I tried snap install netbeans --classic . This gets version 12.
Netbeans version 12 comes with the Metal Look & Feel configured by default. Changing this to the GTK+ look and feel, using Tools->Options->Appearance->Look and Feel->GTK+ with a restart, finally got the menus to the correct system size.
Unfortunately, the Help->About popup still does not respect this, having minuscule fonts. Perhaps there is a better way?
Although "Look and Feel" is an improvement, I would still like to see direct control of the IDE menu fonts. From the Options Fonts & Colors menu.
Running netbeans from commandline with an additional argument --fontsize 12 works for me. Open a console and go the bin directory of netbeans and use the command ./netbeans --fontsize 12. Change the font size to whatever suits you.
In Netbeans in Tools->Options->Appearance->Look and Feel, I could solve the problem.
But in my case, the selected option already was GTK+. Changing to Metal solved it.
Install Netbeans 13.
It should help

I use Raspberry Pi 3 on Raspbian and code-oss 1.32.0 ARM (by headmelted)
you've probably figured it out so far, but I'll answer in case anyone else visits this thread.
All you need to do is downgrade code-oss.

eclipse - swt - using windowbuilder in xfce env

I have some problems with eclipse indigo x64 Linux; The problem is using windowbuilder (the SWT); I tried using gwt or swing but they both cause either windowbuilder freeze or even eclipse crash...
The alike issue it seems I found related info in official eclipse indigo offline Help which says :
How can I prevent the preview window from flashing under Linux using Metacity
In order to create the graphics that you see in the design view,
WindowBuilder Pro creates an off screen window containing the various
widgets and they takes a screen snapshot of them. This works very well
under Windows, OSX and some versions of Linux. Recent versions of the
Metacity window manager (more recent than 2.1.4), however, have been
modified/"fixed" to disallow windows to be opened off screen. This
forces the preview window to appear on screen leading to an annoying
flashing effect any time you make a change. The solution is to disable
the Metacity "fully_onscreen" constraint by patching the Metacity
source code and rebuilding and installing the patched version into
your system.
Here are the steps to follow:
Download the Metacity source code from ftp://ftp.gnome.org/pub/gnome/sources/metacity/
Unpack the source code tarball into any temporary directory.
Chdir into this directory (with the unpacked code).
Find window.c file and open it with your favourite texteditor.
Find a line with "window->require_fully_onscreen = TRUE;"
Replace it with "window->require_fully_onscreen = FALSE;"
Save the changes and close the editor.
Open a terminal and chdir into the directory with the source code (nice if you have already done this)
Run "./configure".
Run "make all".
Make sure that steps 9 & 10 completed without errors.
Become root (or execute the next command via "sudo" depending on the Linux you are running)
Run "make install" (or "sudo make install").
Save your work and close any application you are working with.
End your session (or press Ctrl-Alt-Delete to restart the x-server) and log in again.
You are done!
well seems like I have the snapshot really but, as I can get it, the snapshot doesn't want to dispose or similar so I have either resize the whole eclipse or press F5 to refresh (which works not at once);
I am not sure how to fix the issue in case I have xfce+adwaita installed? I don't have metacity installed; Seems like xfce works with gtk instead of metacity (correct me if I am wrong);
So my question is... how to fix the "window flashing or freezing" if I have :
xfce4
adwaita-dark theme
linux arch x64ce
Thanks
Try to install install libswt-gtk-3-jni and libswt-gtk-3-java.

WindowBuilder Pro – Incorrect display of content pane and element frames in the design view

I need some help with following problem:
Problem:
In the design view frames that appear around selected Swing-elements are not displayed at their correct positions. Also the content pane is not located at its right position inside the window (JFrame). It seems no matter whether layout is used (e. a. BorderLayout, GroupLayout).
For example, the frame of a selected button is display many pixels above or beside the button. In this case, if you want to select a GUI component by clicking it with your courser you should not click on the graphical representation of that element but some pixels above or where ever the frame could be – you have to consider the offset of the shifting.
By nearly every refresh of the design view (F5) or if you shift some components in the content pane the offset of the wrong placed frames changes for some pixels – sometimes the frames are above, sometimes below or beside.
Are there other persons with this problem?
Are there persons that don‘t have these problems with WindowBuilder Pro with Ubuntu 12.04?
What could cause this error and how it might be solved?
System environment under which the error occurs:
One desktop PC / One laptop
Ubuntu 12.04 (with Unity) / Kubuntu 12.04 (with KDE)
Oracle Java 7
Eclipse 64 Bit:
Eclipse 4.3 Java EE / Eclipse 4.3 Standard / Eclipse 4.3 Modeling Tools
Installed under „/opt/eclipse“. The error occurs, no matter whether the folders belong to root or to normal user.
WindowBuilder Pro 1.6.0 (Eclipse plugin installed with eclipse software manager)
I also tried WindowBuilder Pro in Ubuntu 13.04 in VirtualBox. But as soon I am moving the mouse on the palette eclipse crashes.
Hints:
The error seems to occur only, if the content pane is not correctly positioned inside the window (JFrame). Sometimes the content pane is out of place by a few dozen pixels, sometimes it is as wide as the JFrame itself, sometimes it is little bigger than the window.
The error does not occur with Windwos 7 and with Xubuntu 13.04 under otherwise identical conditions (I did not tested Xubuntu 12.04). But the error occures with Ubuntu 12.04 and Kubuntu 12.04.
My workaround is to use WindowBuilder Pro with Xubuntu 13.04 installed in VirtualBox. Of course this can not be a permanent solution, because I want to continue to use Ubuntu 12.04 LTS.
I have read http://help.eclipse.org/indigo/index.jsp?topic=%2Forg.eclipse.wb.doc.user%2Fhtml%2Ffaq.html.
Here the same problem is described, but there are no answers: https://stackoverflow.com/questions/15818379/windowbuilder-eclipse-away-from-the-actual-component?rq=1
Here a possible workaround is descibed: https://bugs.eclipse.org/bugs/show_bug.cgi?id=417224
I have been using Eclipse on Ubuntu for a while. I used both Eclipse Juno and Kepler on Ubuntu 12.04, 12.10, 13.04, 13.10, and 14.04. This error was there on all of those. I am used to living with it. I did not do a through research on that though.
I'm also having some other minor problems. One for example: The toolbars do not update themselves correctly. The buttons on the toolbar are not rendered, and they show up when the mouse hovers on it.
I found out that Eclipse is no as stable on Linux as it is on Windows.
I hope they post fixes on these issues soon.
I am using Ubuntu 15.04 and running Eclipse mars, I thought i was the only one with this problem but it has become a major issue! We can't keep running to virtual machines! There is a reason we ran away from windows to linux!! I have tried following up on some peoples discussions about how they solved their issues but apparently they don't seem to work, they added these lines to the eclipse.ini file
-Dorg.eclipse.swt.internal.gtk.cairoGraphics=false
-Dorg.eclipse.swt.internal.gtk.useCairo=false
Some people claim it has worked for them but others including me didn't find it usefull! Try it, maybe it will work for you
