Ubuntu :: Java Application Opens Without Window Content

Oct 6, 2010

I"m running 10.04 on a netbook. I switched my Java look and feel to Nimbus and now my java application opens with most of the buttons and window content missing. The main menu is there, but otherwise the main form is mostly blank. If I restart the application (not my computer) 2-3 times, the problem is resolved until the next time I have to launch the java app. I did not see this issue before changing the look & feel setting for Java. But the GTK l&F doesn't work for other reasons, so I was forced to make a change.

I'm running compiz and I know the blank windows in Java apps was a common problem a while back. I'm not sure if what I'm seeing is related to that old problem or is something different.

Programming :: Grabbing Window Content Requires Drawable

Apr 9, 2010

I'd like to write a C/C++ program, that would grab content of window (in form of pixmap), which belongs to another application and do something with it. However, I ran into problems already at the beginning. In all toolkits I have searched through, I only found one function that claims to do what I want, namely XGetImage from Xlib. However, among other parameters like Display, coordinates, etc., it requires a Drawable. How do I specify a Drawable, that would correspond to the window I want to grab content of? Is there any easier way to achieve this?

Programming :: Name Of Formula N Things Out Of Collection Of M Things

Jul 22, 2011

I'm working through some problems in a beginners programming book. The author mentions a formula for calculating the number of ways of picking out n things from a collection of m of them:

Code:
/ m m!
| | = -----------
n / n! (m-n)!
But he does not give a name for the formula. Does anyone happen to know what it is called? I need to do some related research.

Software :: Opera Window Not Updating Without Compositing (kde) / How To Work From There

Jul 13, 2011

Under gentoo after the last update, the opera window doesn't update after a few seconds of showing itself. I have to move the cursor over an icon or anything that changes appearance to make it update. This is very frustrating when in the middle of typing a URL, the window stops updating and I'm typing "blind". While playing flash/HTML5 movies this is also quite frustrating

This is under gentoo,KDE 4.6.5, mesa 7.10.3, opera 10.50. I disable compositing because performance is dreadful (Intel graphics) on my external screen, which I use most of the time. For now I've worked around the issue by changing the compositing backend from OpenGL to XRender (where the performance is acceptable), but I'd like to disable compositing altogether.

My theory involves the XDamage extension, but I have no idea about how to work from there.

Ubuntu Installation :: Updating Fails - Downloading Files Window Pops Up But It Is Blank

Nov 22, 2010

Just during the last three days, when running Update Manager, clicking Check, downloading all available updates, then Clicking Install Updates, the Downloading Files window pops up but it is blank. and it stays blank. The little rotating icon indicates something's going on but, NO. Nothing has happened, even after a couple of hours. Trying to close Downloading Files brings up a window to Force Quit. Then trying to close Update Manager has no effect. to shorten the story, finally a window pops up saying that the "AT SPI Registry" is not responding. I'm sure trying the same thing will not yield different results. I'm running 10.04.

Ubuntu :: Can't Boot Into 9.10 / Troubleshoot It?

Apr 8, 2010

I was trying to get rid of some sound issues, in the process I removed Pulseaudio, then I found a post with a couple of packages from a ppa that were made for using Alsa without pulseaudio. I can't find the link now as I'm on a different pc, but 1 package was named Gnome applet, another Gnome media (I think) and I can't recall the third. It really did nothing so I removed them and reinstalled the Pulseaudio packages to atleast get some sound back. I got right back where I started until I rebooted.

Now it gets to the splash screen, flickers a couple times and I get a giant generic login screen If I log into that, I go back to the splash screen and the same login all over again. I tried to repair packages with the recovery mode but it didn't do any good. I also tried renaming xorg.conf just for the hell of it so a new one would be made but that really didn't do anything either.

Ubuntu :: Very Slow Response - How To Troubleshoot?

Jan 11, 2010

My Kubuntu installation (9.10) boots up normally and seems to run fine, other than it is very slow to respond to inputs or change screens/ applications etc. It can take 5-10 seconds to respond to simple requests like changing from firefox to dolphin by clicking in the taskbar. It is dual boot with XP, which also seems sluggish, but is bearable.

The computer is barely useable in Kubuntu because of the slow response. I had 9.04 installed before, same problem. I tried searching for drivers for the on board video, thinking that might be it, but came up empty.

Ubuntu :: Troubleshoot Corrupt Ext4 Filesystem?

Apr 16, 2010

am having issues with a corrupted ext4 filesystem. My machine has run flawlessly for weeks, then all of a sudden I am getting messages that I can't access various directories, and on reboot fsck dumps to a command line. So far I have been able to fix the problem by manually running fsck. However, this is the second time that I have run into this problem; the previous time I ended up throwing out my hard drive and doing a clean install.I am running a clean install of Karmic Koala, software RAID, 4 Gb RAM, two 500 Gb Western Digital SATA drives, with an Intel E7200 2.53 Ghz dual core processor.Among other applications, I run VMware 7.0 for the occasional task for which I need a Windows program.

Ubuntu :: Net No Longer Connects Within VM (W7 Host) / Troubleshoot This?

Sep 18, 2010

I've been running an Ubuntu VM (10.04 LTS) on my Win7 (Home Premium 64bit) desktop successfully for several months now using VMPlayer (v3.1.1). My problem began when I booted up the VM today - my wife decided to reboot the PC without gracefully closing down my applications when Windows told her that she needed to reboot to complete security updates.

When I booted up the VM, the Ubuntu desktop went right back to the exact same state that it was in before the host reboot - the same programs were open, I didn't need to log in, etc. However... I now have no networking. The network icon (NetworkManager Applet 0. shows the red exclamation point. If I click on Auto eth0, it attempts to connect for a bit, and then says "offline".

My VMware Player settings for this VM are configured for bridged networking, and the "network adapter" icon shows online. If I go into the VMWare Player settings and change the networking to NAT, and then click on Auto eth0 again, the networking comes online. However, I don't want NAT - I want this Ubuntu client exposed to my network with it's own IP address.

At this point, I'm really not sure if the problem is within Ubuntu or within VMWare Player, or something on my Win7 host. I have zero skill at troubleshooting within Ubuntu - still fairly new to the linux scene. My Windows firewall is turned off. DHCP is enabled on my network, and the router is available.

Any ideas on how I might further troubleshoot this problem?

Ubuntu :: Troubleshoot No Internet Connection On New Installation

May 21, 2011

I have just installed ubuntu 10.10 on an Acer Aspire 3610 notebook. 2 GB RAM. This notebook had Internet access previously via Windows XP (now erased). Here is the partitioned drive. Two ext4 partitions for ubuntu "/" and "/home". Two ntfs partitions possibly for Windows. I have booted up the fresh installation of ubuntu 10.10. I had some glitch where I saw "Operating system not found' on booting from HDD and I wondered if this was due to failing drive.

But I've run a full test using Disk Utility and it shows as healthy. This message has gone away (I don't know why) and I can boot into ubuntu. The problem I'm trying to solve is simply no internet connection. Here are some outputs from commands ..

Fedora :: Cannot Login - How To Troubleshoot

Aug 9, 2009

I recently installed F11 only to find my soundcard wasn't supported (Asus Xonar Essence STX). I read around a bit and saw that kernel 2.6.30 supported it, so I upped the kernel to 2.6.34

So I configured/compiled my kernel, restarted and it showed up fine in the boot loader. Only problem I have is when I go to login through the login prompt, it acts like it is going to login only to get kicked back out to the login prompt again. I tried to login through the terminal view.... everything checks out there.

I am fairly new to linux in general so I have no idea how to troubleshoot this. I tried finding an error in it but I couldn't find anything.

Ubuntu :: Lucid - Random System Lockups - How To Troubleshoot?

May 14, 2010

Since upgrading to lucid, I have been experiencing regular system lockups. About once a day, my X desktop will disappear and I'll see a TTY with a few old console messages and at that point everything is completely frozen and I must hard reboot.

I have checked out various logs in /var/log and found nothing at all that indicates the system knew anything bad was happening. What is the correct approach to try to narrow this down?
