Just installed Eclipse Mars on Lubuntu 14.
While scrolling up and down in the console or editor - I get a kind of black rectangle covering some text, or the test is kind of twisted visually (lines become non-straight).
Anyone know how to fix this?
Haven't had this in previous versions of Eclipse on the same comp.
Exactly the same thing happened to me installing Eclipse Mars on Lubuntu 14 Toshiba Satellite notebook. I was really looking forward to the day of the Eclipse annual release of Mars and I was disappointed to be so disappointed with 5 minutes on installing.
Anyway, I can confirm that setting environment variable SWT_GTK3=0 by way of export does circumvent the problem. If you open a terminal and type "export SWT_GTK3=0" in the shell, you will also need to start Eclipse via the command line while remaining in the same shell. If you start Eclipse via a desktop launch icon, Eclipse will not see the SWT_GTK3 environment variable and the problem will persist. This is because environment variables in Linux are per-process and an application launched from the desktop is running in a different process to a shell process in a terminal.
So that Eclipse always sees the correct SWT_GTK3 environment variable after starting your machine, best you export SWT_GTK3=0 globally. To do this on Lubuntu, follow these steps:
Open a terminal window
Open the file /etc/profile for editing as sudo (e.g. sudo gedit /etc/profile)
Add the line
export SWT_GTK3=0
at the end of the file.
Save file, quit editor and reboot your machine.
Launch Eclipse Mars and hopefully your scrolling problem is fixed.
This worked for me but, as always, YMMV.
btw. You can check the SWT-GTK3 environment variable was exported after rebooting by opening a terminal window and typing the 'env' command. You should see
SWT_GTK3=0 in the list of environment variables and values that are displayed.
It seems like a new bug:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=469027
It happens also under Kubuntu. Anyway the workaround, at least for me, is to export the following environment variable:
SWT_GTK3=0
I solved my problem in Ubuntu 15.04 with Eclipse Mars by adding the following code in the start of data in the Exec option in eclipse.desktop (/home/.local/share/applications):
Exec=env UBUNTU_MENUPROXY=0 SWT_GTK3=0 /usr/lib/jvm/...
In that way you leave intact your OS preferences and act only on Eclipse starting script.

Hi I'm running Linux Mint 19 and I have just installed vscode using the snapd package manager. I've not used vscode on linux before as my usual editor is emacs. However, on a fresh new install of vscode, the integrated terminal does not work, there is just a non blinking cursor in the top left of the screen, but no prompt and no keyboard strokes are registering. This appears to be a common problem as there are a lot of posts about it if googled, but they are all for Windows versions and none of the solutions that I'm able to try do anything. I've tried to open a new terminal window, but the same thing happens I just get two terminal windows that I now cannot use. I've also tried checking the box that says Code-runner: Run In Terminal, but that does nothing either. What can I do to get this to work please, I looks to me like it is just not connected to either a bash or Zsh(which I normally use). Any help on this would be appreciated.
Instead of starting vscode with its default shell script (usually located on /usr/share/code/bin/code), the integrated terminal only works for me when starting it directly from the compiled binary (typically found on /usr/share/code/code, which is the same as the launcher created by the installer:
/usr/share/code/code --no-sandbox --unity-launch %F
While I searched for a solution in the past I've also noticed that lots of folks solved similar problems just by adding --disable-gpu flag, so might be worth checking out as well.
After upgrading ubuntu to 16.04 eclipse is extremely problematic, almost unusable.
Problems are:
Menu is loading, but not fully functional;
Sub-menies are non-functional;
Deleting project causes hanging and endless progress bar showing;
Updating, installing new software, ... non-functional;
After opening preferences menu on the right stays the same regardless
of which option is selected in preferences sub-menu;
Cannot connect to the update sites;
and so on ...
In terminal is clearly displayed info about bug for pixman_region32:
*** BUG ***
In pixman_region32_init_rect: Invalid rectangle passed
Set a breakpoint on '_pixman_log_error' to debug
What is the solution (beside the fact that bug is reported)?
According to changes in Ubuntu 16.04 and installation manual from eclipse - (I am suggesting this document for reading, at least I got an idea from there), known problems and solutions from earlier versions Ubuntu and eclipse, I am realized that there is the main problem with passing the env again, but slightly different than solutions from previous versions.
Solution is changing Exec in eclipse.desktop file from existing pattern to new one as follows:
From:
Exec=path/to/eclipse/eclipse
To:
Exec=env SWT_GTK3=0 path/to/eclipse/eclipse
eclipse.desktop file have to look like this one:
[Desktop Entry]
Version=4.3.0
Name=Eclipse
Comment=Java/Android/C++/Python IDE
Exec=env SWT_GTK3=0 /opt/dev/tools/eclipse/eclipse
Icon=/opt/dev/tools/eclipse/icon.xpm
Terminal=false
Type=Application
Categories=Utility;Application
Note that there is displayed my path to eclipse.desktop file, but I am left it in order to avoid misunderstandings for format of lines in launcher file. You have to adapt those two lines according to your current needs.
Also note that eclipse.desktop file is usually located there:
/usr/share/applications/
or there:
~/.local/share/applications/
In any case, it can be easily located by running this command:
locate .desktop |grep eclipse
I recently decided to start trying Android app development, so I downloaded the Java SE Development Kit 8 (x86) for Windows (I got Windows 8 64bit, but my guide recommends getting the 32bit one), the Android SDK, and the Eclipse IDE for Java Developers (x86).
However, my Eclipse won't launch when I double click eclipse.exe! Instead, I get the following error message:
I tried adding Java to my Path variable in my Environment variables as suggested in some of the solutions I looked up, but it still doesn't launch properly.
Anyone know what else I can try? Also, if possible, please do not use super-technical vocabulary as I'm new to these kinds of stuff and will not understand you...thank you haha :D
I had the same issue and was trying to install different versions of JDK: 1.6, 1.7, 1.8.
It didn't help much.
The problem was resolved when I changed PATH variable by removing
C:\ProgramData\Oracle\Java\javapath;
In command prompt I also ran following commands:
set JAVA_HOME=C:\Program Files\Java\jdk1.8.0_25
set PATH=C:\Program Files\Java\jdk1.8.0_25\bin;%PATH%
But I think the most important was to remove C:\ProgramData\Oracle\Java\javapath; from the PATH.
I know exactly how to solve your problem. Go to search and put in environment, a prompt will come up and ask you to "Edit environmental variables for your account" click that and a window will pop up. There will be the current paths which are running on the top (you should have your JDK version running, mine is 1.8) and on the bottom part there will be paths to choose from. Select (on the bottom part) the java path and delete it, then click okay. This should work.
If it didn't work, You may also add a new path to the java bin folder which worked for me.
Here is an alternative:
As described here, make sure that you have the -vm option set in your eclipse.ini file.
It must be an absolute path and on 2 separate lines:
-vm
<Absolute Path>\javaw.exe
Save your .ini and relaunch Eclipse
One line answer, remove 'C:\ProgramData\Oracle\Java\javapath;' from your path variable. It will start to work.
Most errors with starting eclipse happen due to multiple JRE or JDK version which makes the installer go nuts.
Solution: Go to Control Panel -> Uninstall Programs
If you're running 64-bit java, then uninstall all Java without the 64bit indicator. If 32-bit, then uninstall all that have 64-bit
It works like magic!
What worked for me was having installed adoptopenjdk11 using Chocolatey package manager:
choco install adoptopenjdk11
I'm having a problem with eclipse galileo on ubuntu 64-bit system. when ever i open it the splash scree turns gray but keeps loading and then when eclipse opens it shows the secure storage password request and hangs. I dont know what could be wrong, it used to work fine before, if you have or had the same problem please tell me what to do
I have had this happen on Galileo (3.5) and Helios (3.6).
If you delete .eclipse you will lose all software installed through the Help | Install New Software menu option.
It is enough to delete the file ~/.eclipse/org.eclipse.equinox.security/secure_storage
Try clean $HOME$/.eclipse directory.
Its better to just rename at first.
See what happens
This happens to me whenever I shutdown eclipse with the history tab open.
While not the best solution, to solve it I start eclipse with sudo. I let it finish loading, then select a different tab than history. I Shutdown eclipse, then I recursively change the owner of the files in .metadata back to my main user.
In case you need the command: (in my case I run this from /home/wally/workspace)
sudo chown -R wally:wally .metadata
As far as I can tell, there's some race condition going on.
(also, it's likely that you won't use exactly "wally:wally" but "your username:your group)
Try this:
export GDK_NATIVE_WINDOWS=true
then run eclipse from command line from the same terminal window.
I would suggest removing openjdk from synaptic and install sun java. Once you do that , use "sudo update-java-alternatives --set java-6-sun" to use sun-java as the default JRE.
Eclipse used to work really slow for me, and this method worked. Maybe it helps you too.
I just got this MSI wind netbook and tried to run eclipse on it. I installed JDK6 on the netbook already. Whenever I open eclipse there is nothing show up on the screen except a "warning sound" that alerts. What is the problem here?
ps.I just started learning java.
Most likely the Eclipse starter program can't find where you installed Java. Since Eclipse is a Java program, it needs a JRE installed (comes with the JDK typically) to run. Assuming you're running Windows on your MSI Wind, check to make sure the java executable is on your path in your computer environment settings (windows key + printscreen button, or windows key + pause button are the shortcuts to open the computer properties dialog if I remember correctly. Then go to advanced).
You can test if java is on the path by opening a cmd.exe shell window and typing 'java'. If it says it cannot find java, then you need to fix the path.
See this link for additional troubleshooting details: http://www.eclipsezone.com/eclipse/forums/t99010.html
You could try reinstalling the JDK. Perhaps having it on a different disk than the default (D: versus C:) is causing some trouble? It certainly isn't a problem with the hardware, I'm running Eclipse on Windows on an MSI Wind.
Use "Add/Remove programs" in the control panel to remove the java versions you have installed.
Then visit "java.com" and use it to install Java, and verify that it is working. You do not need more than that to use Eclipse.
