Ubuntu Multimedia :: Java Runtime Environment Flickers Black
Jan 2, 2011
Just did a fresh install of 8.04 on wifes laptop (Inspiron 1521) as it has been a nightmare getting things to work with it's hardware and 8.04 seems to have the least issues. Did the first section of the Comprehensive Multimedia and Video Howto stickied at the top of this forum, then dled minecraft to test things out. Heres the terminal readout
I have installed IE6 [URL] On IE6 Adobe Flash Player, Adobe Shockwave Player 8.0 & Real Player 10.5 are working fine. When I tried to embed J2SE-Runtime Environment-1.5_17 by clicking 'Windows 98 & Windows ME Online'
---> 'open' ---> 'Modify' ---> 'Installation Completed' ---> 'Finish', i hoped that
everything will be fine. However, after closing the browser and restarting it I found that jre has not been installed on IE6. Incidentally the same thing occurred on debian-4.0r0-i386-netinstall.iso OS.
I am trying to install the Matlab 7.5 compiled runtime for 64-bit Linux (MCRInstaller.75.glnxa64.bin) and keep getting a "No Java Runtime Environment(JRE) was found on this system." error message.
I understand the JRE is bundled with MCRInstaller and will self-compile/install. However, I don't have admin access, could this be the source of the problem? If so, how could I fix it (not sure how to direct it to install locally without going into the source code)?
I got around this error before, but stupid me didn't write down what I did and I forgot.
I tried a lot but I can' t enable java in firefox. I' ve installed java jre 1.6.20, I created symbolic shorcut to .mozilla/plugins directory but it doesn' t work. By the way /plugins directory wasn' esixt and i created it in .mozilla dir. I use opensuse 11.2 and firefox 3.6.3.
Some files are generating in my Documents folder named hs_err_pid4214.log ........ different logs files are generated. I put the contents of one of them: Code: A fatal error has been detected by the Java Runtime Environment: SIGSEGV (0xb) at pc=0x00007f1714b33e30, pid=4214, tid=139736470193920 JRE version: 6.0_24-b07 Java VM: Java HotSpot(TM) 64-Bit Server VM (19.1-b02 mixed mode linux-amd64 compressed oops) Problematic frame: C [libsvllx.so+0x82e30] _ZN26SvNumberFormatsSupplierObj18SetNumberFormatterEP17SvNumberFormatter+0x0 # If you would like to submit a bug report, please visit: [URL]. The crash happened outside the Java Virtual Machine in native code. See problematic frame for where to report the bug.
My firefox can't auto install java runtime evnviroment. I have try manual download at http://java.com/en/download/linux_manual.jsp?locale=en&host=java.com (Linux x64), and I have set up it follow intruction. But it is not effect.

Running programs in X (WindowMaker) as another user.
Until recently (Debian Stretch) I was able to run graphical programs in X as a second user, like so:
- log into X as user1 - run "xhost+" - run "su - user2" - run any graphical program (gthumb, konquerer, ...) as user2
Now when I try to run a program as user2, I get
Code: Select all user2@localhost:~$ gthumb error: XDG_RUNTIME_DIR not set in the environment. Segmentation fault
XDG_RUNTIME_DIR for user1 points to /run/user/1000 which I believe gets created by pam_systemd when logging into X. However, doing "su - user2" does not create /run/user/1001. Why not? And how do I get on-the-fly user switching working again?
Related to this, /run/user/1001 not being created on user switch has always caused me some grief b/c audio would not work for user2. But I could work around that by piping pulse through a socket. But now graphics are also broken and that I can't seem to work around.
I'm having touble with a java web application. It's online learning through SEEK's skillport website and it uses JRE runtime environment to display the content. I have java installed for Ubuntu as per java.com's website instructions, and I can launch my web application, however it only displays the left half of the screen. The other half is just not there. I'm running Ubuntu 10.10, all updates applied. I've also tried installing OpenJDK Runtime Environment (IcedTea6 1.9.2) but the same sypmtoms occur. Skillport's support centre only supports Suse Linux so they couldn't help me. I'm wondering if Java is the problem or maybe a browser issue? I've tried in Firefox as well as Google Chrome for linux - same result. Currently I'm having to boot into Windows so I can do my study. Everything else works fine in Ubuntu.
I recently gave the boot to Windows and installed Fedora 10. Under Windows, I was using VirtualBox for all of my virtualized computing needs. I had set up a virtual network with two virtual machines - one running Windows Server 2K3 and the other running Windows 2000 Pro. I could run both VMs at the same time and still use the host OS. Now I am trying a similar setup under Fedora, I am using VirtualBox to run Server 2K3 and Windows XP. The problem I encounter is that when I run one VM, one of my CPU cores rockets to 100% usage and the other hovers around 40% - 60% usage. Is there a way to enhance performance so I can run both VMs at the same time? Third, what would be the effects of me installing the Xen runtime environment package or the Xen emulator for KVM?

Yet when I go to a site like keepvid.com and enter a valid URL I get: Error: Please click here to download Java. If you already have Java, please restart your browser and try again. It appears you do not have Java installed or it is disabled on your system. You can get Java here. If you are still having difficulty with Java, check here for installing Java, or here for detailed instructions on enabling Java in your browser.
I downloaded Java into my home folder instead of downloading it in my usr folder because it wouldn't let me(even when I was root user). It is present in my home folder with its own directory, but I am unsure how to use it. I downloaded Java to try to play Minecraft, but when I open then .jar file with the directory nothing happens. The actual directory contains the following
folders:bin,javaws,lib,man,plugin,copyright,licens e,a read me file, thirdpartylicensereadme, and a welcome.html file. I don't like running Minecraft with OpenJDK because it lags tremendously and it won't close, and I heard the "real Java" runs it much better.Did I download it incorrectly, if so can you tell me how?
AMD 64-bit quad core Scientific Linux 6.0 Firefox 3.6 Firefox is complaining that I need a java plugin. Apparently, it has to be installed manually. I managed to download jre-6u25-linux-x64.bin and saved it on my desktop. Then a ran jre-6u25-linux-x64.bin and it created a directory on my desktop called jre-6.0_25. Within the directory there the following subdirectories: bin, javaws, lib, man, and plugin.
I'm trying to install Open Rocket : [URL]. I don't think I have java installed. I went to software center and tried to install "OpenJDK Java 6 runtime" and it says package dependencies cannot be resolved. I tried doing sudo apt-get install through terminal and it was dependent on a long list of things:
I have tried to install and enable java, follow the instructions of this link:[URL] when I try to enable de java, for firefox, I can't linked de java with the browser, because I can't find de folder "plugins" on the path --> /lib/usr/lib/firefox).
I just installed Ubuntu10.10 (i had 9.10 before that). I am trying to run VisualVM (which was already installed) and i get the following error "You are running VisualVM using Java Runtime Envoronment (JRE). Please use Java Development Kit (JDK) to run VisualVM"
I have Sun JDK installed. How do I instruvt VisualVM to use the JDK?
I'm new to the linux world and its been quit sometime since i've done any programming. However, I'm writing a program which simply calculates the load average of a process. In doing this I need to use the uptime command for linux in a java program. I've done a little bit of searching on the net and it mentions this is possiable by using java runtime command. Unfortunatly though I have yet to find a working example of this. I've tried just simply reading the /proc/uptime file but I have no clue how to format the 2 numbers in seconds to make it the same as if you just typed in uptime in the linux command prompt.
I am working on other's pc. I got a problem. I put the export sentence in the user's ~/.bashrc and root's ~/.bashrc. So when I type java -version either in user account or root account in the terminal, it works correctly. But when I type sudo java -version, the error appears, it cannot find the java. I am really confused. Is sudo different from directly using root account? How to set java environment when I type sudo in user account?
I am a total beginner to ubuntu. I have installed ubuntu 10.04 desktop edition with a CD on my laptop as only OS. So far (three weeks) ubuntu has convinced me. However, my screen starts flickering regularly after a while (even when the computer is idle) and the only solution so far has been to suspend/shut down. The flickering makes the computer unusable and doesn't stop if not shut down/suspended. Beside this issue the graphic seems to work fine.
My Computer is an ASUS F3J, the video card is a ATI Radeon X1700. 01:00.0 VGA compatible controller: ATI Technologies Inc M66-P [Mobility Radeon X1700] this is the xorg0.log:
Code: X.Org X Server 1.7.6 Release Date: 2010-03-17 X Protocol Version 11, Revision 0 Build Operating System: Linux 2.6.24-27-server i686 Ubuntu
I recently switched to a setup in my living room where a CPU is hooked to a big Toshiba 1080p TV through an HDMI cable. We had to buy a new video card to make it work - a nvidia GeForce 210 with an HDMI out.The problem has been that when I fullscreen a browser on the TV (Chrome OR Firefox), the TV will suddenly lose its signal, flicker, then come back again. If I try and watch a ..... video, it starts to happen more and more quickly.It doesn't do this at all when I watch a movie on VLC. My guess is that it's a driver issue with the new video card - we never actually installed anything to update the drivers, just plugged it in and it started up.
My last setup (years ago) ran fluxbox so because it was familiar I installed it as a secondary to xfce right off the bat. I download a lot of different stuff because I like to try out all the apps I can find but somewhere I broke something. I can still run fluxbox fine, but nither the Xubuntu nor Xfce sessions will run now. Last thing I remember changing was pulse audio(removed it for an experiment I was trying with jack audio), not sure if it is connected but when I try to login to xfce the screen goes black, flickers a few times then it brings me back to the login screen.
I tried failsafe but everytime I do my monitor gives me a "frequency out of range" error. I tried purging and reinstalling xubuntu desktop and xfce settings but I am thinking its my xorg config. My laptop is a Toshiba satellite M305D-s4830 with ATI Radeon 3100 mobile graphics card and I am running Xubuntu 10.10. Unfortunately I also broke the screen, so right now I am stuck with an external monitor till I get a new one.
I just upgraded to Ubuntu Maverick v 10.10 and loving it. However, I have encountered a problem with playing any type of video whether it be Xvid, AVI, h264, MKV or AAC. I have tried many players from smplayer, mplayer, kmplayer, vlc, etc. but I am still having the problems. I have read some posts on here and I've disabled compiz, tried the X11 tweak and updated my Nvidia drivers. I don't know if I am missing some type of codec or restricted plugin because I have ample space and resources are readily available while playing the video.
I'm using the Ubuntu 10.04 LTS Desktop 64-bit distribution. Hardware is the Dell Vostro 1015; laptop with Intel (g)45 express chipset with Intel x4500MHD graphics accelerator. Celeron 900 2.2ghz single core, 1GB RAM.
The issue is I have smooth scrolling enabled in Firefox. And whenever I scroll the page, it's very choppy/laggish/not smooth at all. When I go on ..... to watch a video, any slight scrolling will cause it to flicker like crazy. The effect reminds me of when I run Windows without installing drivers for the video card.
Now I wanted to make sure it wasn't a hardware issue, so I installed Windows7 and did the exact same thing. Everything runs smoothly, I can smooth scroll no problem, and video playbacks without any flickers whatsoever. It is a lower end laptop, which is basically for the occasional ..... and web browsing.
I will try the 32 bit edition in the meantime to see if it helps. I was under the impression that 32bit limits your maximum ram to just under 4GB. (I planned to upgrade the laptop a bit)
