Ubuntu :: Degrade - Java Apps Freeze And Require Moving The Window Offscreen (below The Screen) To Redraw
Feb 11, 2011
Yes im refering to Windows Degrade and how over time windows just running will degrade and start causing errors. DLLs go missing and bizzare things. Ive seen wierd things happen on a windows machine that is dedicated to one function. Well to my point, recently I have been having many linux issues, not like normal or anything throughout the years I have experimented with linux though.
1)entering fullscreen on VMware crashes linux sometimes (no Ctrl+Alt or Ctrl+Alt+F2 ect)
2)using a different monitor haults the virtual machine while other monitors do not (I have 4)
3)Java apps freeze and require moving the window offscreen (below the screen) to redraw
4)general linux freezing
5)glitch with xinerama that repeatedly teleports mouse between two monitors causing the system to be unusable (no Ctrl+Alt+F2 or anything either)
At first I thought they were all related to VMware but they may not be. I run VMware everyday for my slingbox and light EXE-ing when wine isnt an option. So I may not be asking for fixes to all these problems but whats going on? Ive seen linux installs last years and believed linux to not degrade.

When I run it, the window shows up but Qt doesn't draw in the background. I end up with phantoms from windows behind it: URL...The window will draw the background correctly when I resize it -- MOST of the time. And sometimes there will be a noticeable delay between resizing and drawing in the window.Am I missing some libraries? Is this a bug? Maybe there's something else I can look up to find a solution?
I'm running sid, my window manager is fluxbox, and my video card is a GeForce FX Go5200 64M.I should note that this works perfectly well on another computer I have that's running sid as well.

I've compiled a basic Qt app as given in this tutorial: [URL]... When I run it, the window shows up but Qt doesn't draw in the background.

I find xcompmgr more than adequate for making a desktop look pretty modern, and I don't like the more extravagentCompiz gimmicks - but there is one thing that irritates when using xcompmgr which someone here might have worked round.
Rounded window borders don't draw and redraw properly when using the Terminal (gnome-terminal and the LXDE and Xfce ones) or system monitor and moving them from their default place. You get this little white botch at the corners. I'm not massively technical and I'm ambivalent about how much more I want to learn as I have plenty of creative outlets already, but I would like to solve this. Somehow xcompmgr is treating these programs as a different class? It's capable of drawing the window borders properly as it is just these two programs that get botched. Possibly this doesn't get noticed as maybe people usually use xcompmgr with openbox and LXDE and their square window borders. I did do a search but there was nothing matching what I saw.

I am running Ubuntu 9.10 on my desktop computer which runs a Core 2 Duo at 3.2ghz and I have 2 gig of RAM. I have installed all the latest Ubuntu updates.
In Firefox, I have about 70 bookmarks in the bookmarks toolbar. Obviously the bar can't show 70 so most of them are in the dropdown section of the bar on the right. When I add a new bookmark, Firefox adds it to the end of the dropdown. Sometimes I want them to be closer to the top so I scroll down, click and drag it up closer to the top. In Firefox under Windows this works fine. However in Firefox under Ubuntu, as soon as I start to drag it up Firefox turns gray and Ubuntu totally locks up. Everything in Ubuntu freezes. The main bar at the top stays color, only Firefox turns gray. I tried clicking around but it's frozen. I tried pressing Esc, ctrl-alt-delete, and a number of other keys but noting will unfreeze Ubuntu. I have to physically turn off my computer and reboot.

OpenSuse 11.2 (64 bit) KDE 4.3.5
Printing from KDE no longer works. Opening a simple text file in Kwrite and attempting to print the document causes kwrite to hang. While Googling on this problem I came across this thread. The case is very similar.
[URL]
Running kwrite from the command line does not provide any information to diagnose this behavior. Printing works from Firefox and OpenOffice. Printers produce test pages ok.
This behavior came about after the HP C6380 stopped scanning. During my investigations I was forced to reinstalled hplip. This may have broken something.

Sometimes when I type something to run apps on krunner (alt + f2) it gets freeze for about 10 seconds. I say sometimes but sure it happens most of times I use krunner.

I just installed a game, TripleA, that is supposed to run great on Ubuntu using JAVA. I extracted the game to the recommended folder.I have JRE already installed via Install and Remove Applications utility. Is there something else I should do? Installing JRE manually seemed a bit troublesome.Is it "safe", i.e. will the other apps that use java still work properly?

When I move a window from one workspace to another, the window position relative to the workspace does not stay the same. It ends up being lower by what appears to be the height of the top panel bar. It's as if the position is calculated by adding the panel bar height, without having first subtracted the panel bar height in the current workspace to make it consistent.

My computer freezes and I am trying to diagnose the issue. When.. Using Devede to convert avi to dvd. (almost always) Using Firefox on pages using macromedia flash or java apps. With multiple windows open using terminal. I am strongly leaning towards this being a HARDWARE issue.

I just moved from the netbook remix of Ubuntu to the normal version... I really didn't like the desktop layout of UNR. One feature I did like, though, was that every time a window was maximized, the title bar was integrated into part of the top panel... which saved a lot of space on this tiny little screen. Is there a nice way to get that feature on the normal version of Ubuntu?

when i move a window around on my desktop its splited up into two where the bottom half sluggishly follows the top half i.e. the top half of the window is leading as i move the window around the desktop rather than moving around smoothly(i.e. moving the say vlc around without the window splitting[moving it around as one]. this issue also persist in fire fox where when i scroll down a web page, the page is split in two where one half of the webpage overlaps the other dependant whether i scroll up or down.
my computers configuration is:
64bt UBUntu 10.04
MSI 870A FUZION......
AMD phenom II x6
ATI HD 4550(XFX)

I have a toplevel window that I want to place depending on another toplevel window. I use gtk_window_move(widget, x, y); At startup this function is called several times and y is changed ones from 412 to 413 and x is always 0(checked with gdb in netbeans). The window gets placed at x=10 and y=400 or so. If I do not use variables but pure ints for x and y it gets placed correctly even if its the same values. I suspect that my window manager notice this change of y and place the widget for me. Is this correct and how do I tell the WM not to do so?
This change of y is due to window size is just a local size and not the correct one as in X. Can i force uppdates from X to the local cache?

When I install Ubuntu 11.04 with Wubi, I get this freeze screen after I reboot and get past the Ubuntu splash screen: url
As you can see, it's a scrambled picture of my Windows desktop. This happens with every other version of Ubuntu also.
I'm running a 64-bit PC and I don't wanna waste another CD or use a USB to install, because I actually progress further in my efforts whenever I use Wubi.

I've Intellij Idea and Netbeans installed on my Ubuntu desktop. Both worked fine while I was on 10.10.After upgrading to 11.04 both of them became irresponsive to Ctrl+C/Ctrl+V/Ctrl+{Any alphabet letter} combinations. However these combinations work in non-Java apps (e.g. gedit).Besides that Ctrl+Alt+L (Lock screen) is not handled by the system, no matter what application is active.Disabling unity does not help. Starting in ubuntu classic w/o effects does not help either.

I noticed that while Compiz has every keyboard shortcut imaginable for moving windows between desktops, there's no shortcut for moving a window to a specific display when using dual monitors.
So far, I've found the best method is to use the command line automation tool: xdotool - [url]
Here's what I did:Test out the xdotool in a new terminal window using this command
Code:
This should move your terminal window 100 pixels in from the top left of the leftmost display.
Find out the top-left coordinates of your rightmost display by using the Nvidia X Server Settings tool in Main menu > Administration or via the terminal:
Code:
Go to X Server Display Configuration and click the rightmost Display in the layout section. Its position offset should be displayed in the position field. Make a note of these two numbers.
Create a script to move your window, either to the leftmost screen or the rightmost screen, using this code or similar:
Code:
Remember, the number at the end is an argument that denotes the display (1 for left, 2 for right). Assign a keyboard shortcut to your custom shortcut. Repeat for the right display. Now when you press the keyboard shortcut, the active window should be moved to either the left or right display!

If I have Dolphin up and running, I will activate a folder, hit Enter, and nothing happens unless my mouse is moving around the screen.I may have Chromium Browser or Firefox running with another app, and when I use Alt-Tab to switch tasks, the app selector window will not appear unless I'm moving the cursor. And once I have chosen the app to switch to, it will not actually make the switch unless the cursor is in motion across the screen.I am running Kubuntu 10.04, KDE 4.4.2

In (Gnome) Ubuntu there is a keyboard shortcut Ctrl+Alt+Shift+(Up|Down|Left|Right) that allows the user to quickly move a window from one workspace to another. I've been looking for a similar way to accomplish this in (KDE) Kubuntu. I know that you can right-click on a window in the Task Manager and use "To Desktop" to move a window, but I'm just curious if the same thing can be accomplished with the keyboard.

I'm using Arch Linux with kernel 3.0 and brcmsmac to manage my wireless card. My desktop environment is KDE 4.7 and I use networkmanager to handle network. Recently I've been affected by a weird problem wherein whenever I'm connected to a network Java apps such as jEdit take ~30 seconds longer to start but behave normal once started. What could it be due to and how can I fix it?EDIT:The problem occurs both with Oracle's JRE and OpenJDK, both versions 1.7. I'm behind a HTTP proxy, if that makes a difference.EDIT:I've discovered the cause of this problem. My /etc/hosts file had the wrong host name in it. After correcting this to my hostnameeverything is fine.

I've been running Ubuntu 10.10 very smoothly for a while now. Decided to upgrade to 11.04 - managed to corrupt the hard disk the first time by letting the laptop hibernate part of the way through but reinstalled from a live CD of 11.04 and it's now working except for this issue.
If I shut the screen on my laptop (or press the screen off button) either the screen won't come back on or it will but frozen (I can move the mouse but not click on anything etc.) In this state music continues to play (from spotify under wine) and if I press my hibernate shortcut (power button) the computer hibernates, only to wake into the same situation. I've got a Dell Latitude D520, upgraded to a bigger hard disk and more ram - the ubuntu partition has 50gb. Windows is working fine.
Edit: I noticed a sticky thread which includes something about a blank screen but I think this is a different issue?

1) What is the window effect called that adjusts all open windows into a viewable position while darkening the backgrounds?2) Is there a source or an already made list of packages ready so I can install it on a different operating system? I'm sticking with F14 as my main Desktop Os, however, would like to use this on a Live USB with Archbang Linux.

I have found a couple of posts complaining about this problem but none offering solutions. In a nutshell, I want to prevent ALL programs from creating new windows that steal the keyboard focus away from whatever window I was just using. The most common offender is Synaptic when running updates/installs. I will be typing an email, playing a game, whatever, and all of a sudden a new window will pop up, steal focus, and if I'm not paying enough attention, whatever I'm typing will interact with it and cancel something or say yes to something before I even realize it. Another really bad offender is Firefox with the dialogs to accept cookies or entering/leaving a secure website. I still want all of those dialog boxes to appear but I don't want them to automatically steal focus from my other applications. Another user suggested having them blink in the task bar and I like that well enough if it is possible.
Is there a way to lock the focus to the active program/window unless the end user switches it away (i.e. no stealing)?
One post said something about window rules but gave no details. A lot of posts talk about the mouse cursor position selecting the window option (which I do not want and would not fix this problem anyway). One post said it was fixed in Feisty (guess it came back...)
