• ATI (fglrx) Dual monitor / laptop hot-plugging

  - by Brendan Piater

  I feel like I've gone back 5 years on my desktop today. I'll try not dump to much frustration here... I been running 12.04 since alpha with the ATI open source drivers and the gnome 3 desktop. I been generally very happy with them with only small issues along the way. Now of course it does not support 3D acceleration 100%, so games like my newly purchased Amnesia from the Humble bundle would not play. OK, no worries, the ATI driver is in the repos so let me have a go I thought. With all this testing that's been done with multi-monitor support, what could go wrong...? How I use my computer: It's laptop, with a HD 3670 card in it. I spend about 50% of the time working directly on the laptop (at home) and about 50% of the time working with an additional display connected (at work), multi desktop environment. What happening now: installed drivers things seemed to working, save some small other bugs (not critical) this morning I take my machine and plug the additional monitor into it, and nothing happens... ok fine. open "displays" try configure dual display, won't work open ati config "thing" (cause it is a thing, a crap thing) and set-up monitors there reboot it says (oh ffs, really.... ok) reboot, login and wow, I got a gnome 2 desktop (presume gnome 3 fall back) and no multi-monitor...great. (screenshot: http://ubuntuone.com/5tFe3QNFsTSIGvUSVLsyL7 ) after getting into a situation where I had to Ctrl + Alt + Del to get out of a frozen display, I eventually manage to set-up a single display desktop on the "main" monitor ok.. time to go home... unplug monitor... nothing happens.. oh boy here we go... try displays again, nothing, just hangs the display.. great. crash all the apps and reboot... So it's been a trying day... What I really hope is that someone else has figured out how to avoid this PAIN. Please help with a solution that: allows me run fglrx (so I can run the games I want) allows me to hot-plug a monitor to my laptop and remove it again allows me to change the display so include the hot-plugged monitor (preferable automatically like it did with the open drivers) Next best if that's not possible: switch between laptop only display and monitor only display easily (i.e. not having to reboot/logout/suspened etc) Really appreciate the time of anyone that has a solution. Thanks in advance. Regards Brendan PS: I guess I should file a bug about this too, so some direction as to the best place to file this would be appreciated too.

• Configuring the SOA Human Task Hostname by Antonis Antoniou

  - by JuergenKress

  When a human task is opened in BPM Workspace, it will try by default to connect to either localhost or the server's alias. So if you try to access the BPM Workspace remotely (from a computer other than where Oracle SOA is running) you will get an http error (unable to connect). You can fix this issue at run-time using the Enterprise Manager (EM). Login to EM and from the farm navigator select your composite by expanding the "SOA", "soa-infra" and your partition node.

• Efficient inline templates and C++

  - by Darryl Gove

  I've talked before about calling inline templates from C++, I've also talked about calling inline templates efficiently. This time I want to talk about efficiently calling inline templates from C++. The obvious starting point is that I need to declare the inline templates as being extern "C": extern "C" { int mytemplate(int); } This enables us to call it, but the call may not be very efficient because the compiler will treat it as a function call, and may produce suboptimal code based on that premise. So we need to add the no_side_effect pragma: extern "C" { int mytemplate(int); #pragma no_side_effect(mytemplate) } However, this may still not produce optimal code. We've discussed how the no_side_effect pragma cannot be combined with exceptions, well we know that the code cannot produce exceptions, but the compiler doesn't know that. If we tell the compiler that information it may be able to produce even better code. We can do this by adding the "throw()" keyword to the template declaration: extern "C" { int mytemplate(int) throw(); #pragma no_side_effect(mytemplate) } The following is an example of how these changes might improve performance. We can take our previous example code and migrate it to C++, adding the use of a try...catch construct: #include <iostream extern "C" { int lzd(int); #pragma no_side_effect(lzd) } int a; int c=0; class myclass { int routine(); }; int myclass::routine() { try { for(a=0; a<1000; a++) { c=lzd(c); } } catch(...) { std::cout << "Something happened" << std::endl; } return 0; } Compiling this produces a slightly suboptimal code sequence in the hot loop: $ CC -O -xtarget=T4 -S t.cpp t.il ... /* 0x0014 23 */ lzd %o0,%o0 /* 0x0018 21 */ add %l6,1,%l6 /* 0x001c */ cmp %l6,1000 /* 0x0020 */ bl,pt %icc,.L77000033 /* 0x0024 23 */ st %o0,[%l7] There's a store in the delay slot of the branch, so we're repeatedly storing data back to memory. If we change the function declaration to include "throw()", we get better code: $ CC -O -xtarget=T4 -S t.cpp t.il ... /* 0x0014 21 */ add %i1,1,%i1 /* 0x0018 23 */ lzd %o0,%o0 /* 0x001c 21 */ cmp %i1,999 /* 0x0020 */ ble,pt %icc,.L77000019 /* 0x0024 */ nop The store has gone, but the code is still suboptimal - there's a nop in the delay slot rather than useful work. However, it's good enough for this example. The point I'm making is that the compiler produces the better code with both the "throw()" and the no side effect pragma.

• Audio Stutters at gdm

  - by Allan

  Ok I have a problem every 2 times out of 3 I login (I cant be specific it fairly random) I get a Stuttering GDM warning (not the login sound just the Bell sound to wake you up) the only way to stop it is to login I have a Fujitsu Siemens Amilo 1718 with a 2gig of memory (only hardware mod) using 10.10 Maverick and I have disabled KMS as my system was freezing as per the release notes. The only time this has happened before on the same machine was when I gave Kubuntu a try when 10.04 came out then it happened at the login screen and at random times while listening to music in any program. By the way audio is fine as is almost everything else once I have logged in. I would like an answer to this as I am an advocate of Ubuntu and its kind of embarrassing when the first thing that happens is *bing*. as requested Daniel alsa-info Pulse verbose log Not sure how useful the pulse log will be as I cant replicate the bug with a terminal open but I wouldnt be asking the question if I knew the answer so..... Edit 24/12/2010 ......been living on cocktail sausages and pickled onions for five days now made a make shift splint with cocktail sticks..... oops so updated the alsa drivers but I still get the same message in the dmesg No response from codec, disabling MSI: last cmd=0x10a90000 googleing it brings up a forum post from some other distro with a green logo the only common denominator seems to be graphics ie ATI Radeon XPRESS 200M which is why I have had to turn of kms as the chip is so old that small mice try to eat the "kernel" ;) funnily enough following the bug link at the end of the post, I found a comment about "Ubuntu Black Magic" so mabey I am coming at this from the wrong angle...... Bad Joo Joo any one. I will try the second part of Daniels Fix and Update with the result. The final Edit: (Plays air guitar) In the end neither of these solved the problem as such However I have given Roland a tick for reminding me of the solution and I gave Daniel the Bounty for the effort in trying to solve the problem. The answer for future readers was the enable the correct HD Audio Model I found the answer back when using Karmic Koala 9.10 in this forum post Amilo Li1718 Skype - Can't get it working... the model is options snd-hda-intel model=3stack position_fix=1 enable=yes which can be added to the end of alsa-base.conf thanks all for helping and hope anyone with a similar problem will find the answer here.

• Need help to install Ubuntu on Win7 Alienware M17xR3, installing not working

  - by Rodrigo

  Please I need help to install linux on my computer to start analyzing Next Generation Sequencing (molecular genetics) for my work. I've tried to install from all different ways and forms and it gave me different errors. First I will describe my system: Alienware M17x R3 Raid Drive 596GB (2x 298 GB) Windows7 primary partition C: The hardrive is divided in 3 primary partitions (can't do 4 don't know why) 1st: Fat16 no name capacity 40mbs almost not used (has files like command.com, dellbio.bin, dellrmk.bin and oobedone.flg) I dont know what this is for but is blocked and non system (Status:none). 2nd: Recovery NTFS 9GB (Status:system) and it seems to have boot files. 3rd: CD: Windos OS (status:boot). And I have 2 Logical drivers F: data for backup and games :D (300gb) G: For trying to install the Linux (Already tried with Fat32, Ext2, ext3 and ext4) Installing with Wubi on F: and G: Instalation looks good on windows ask to restart dos mode appears: try (HD0,0) non-ms:skip try (HD0,1) NTFS5: No Wibildr try (HD0,2) NTFS5: Error: "Prefix" is not set. Installing with Wubi on C: Installation looks good on windows ask to restart dos mode apears: Mount denied becouse NTFS volume is already exclusive opened, the volume may be already mounted or another software may use it which could be identified for example by the help of the 'FUSER' command Mount devdm-4 Could not find installation files /ubuntu/install custom-installation Run 'Chkdsk /r' on windows and restart...blablablalba... that should correct. done this didn't work. Tried installing with USB drive and after burning a CD with the Iso file download from the official website: I've tried the option to install along windows with a G: drive in FAT32, EXT2,3 and 4, I've tried to leave unallocated data, without the driver G at all... appears this everytime: http://i.stack.imgur.com/eo2Ie.png pres ok it ask me to: Not possible to install the boot loader at the location: specify new location: I've tried to select all the drivers non is accepted If I ask to continue without installing the boot loader he ask me to install later by myself which I'm trying to figure it out but I'm not really good to understand how ppl get to the programming part like a DOS to write down couse I'm a newb and I've dont work on dos or linux before... I've read that the boot loader has to be installed on the primary partition, but I'm not sure what I can delete from those 2 partitions that would let me get 1 extra... and it seems that the one that windows use is protected to write down so the software is not touching it... Please if someone have any idea to help me out... I've got a course tomorrow of how to use the software to analyze the data and I wanted to take my computer with me, so I've passed the last 3 days trying to search different ways to solve. My question is also post on the bugs.launchpad.net link here: lounchpad.net bug #882695

• Deleted windows partition, now I can't get into Ubuntu

  - by Alejandro

  Back story: I installed ubuntu with wubi. I had windows on one NTFS partition, then I made a new NTFS partition in which I put wubi in and where My ubuntu OS was born. Eventually I moved /home into another partition and made a swap partition, but I digress. I deleted My original NTFS partition where windows is not thinking it would not matter but now I can't get into ubuntu. And the weird thing is that when I boot my computer I still see the option to boot into both windows and ubuntu. When I try to boot into windows, It tries to fix stuff and never succeds. When I try to boot into ubuntu, it shows me "cannot find GRLDR in all devices. Press CTRL+ALT+DELETE to restart". so, what do you guys think? I just want ubuntu running again, with all my stuff in /home there and all my system preferences how I like them.

• How do I reset my Ubuntu 12.10 password?

  - by Salvador Yniguez

  So my sister gave me this old laptop that has Ubuntu 12.10. The problem is that she has a username administrator password, but she forgot it. I've tried using GRUB and launching recovery mode and using the root shell prompt. And I type the "passwd username" command, and it tells me to type the new UNIX password, but when I try to type a new password it's like my keyboard doesn't even work. It types nothing. What's the problem? Why does my keyboard not type anything when I try to reset the UNIX password? It always works perfectly fine. I'm grateful for any help, thank you.

• Ubuntu boots up maintenance shell?

  - by Andrew

  Any time I try to start up my computer it goes to a screen titled GNU GRUB version 1.99-12ubuntu5 I can then choose from 5 different options. If I try to just boot Ubuntu, with Linux 3.0.0-20-generic it then goes to a screen saying: mountall: /lib/x86_64-linux-gnu/libc.so.6: version 'GLIBC_2.14' not found (required by /lib/libply.so.2) General error mounting filesystems. A maintenance shell will now be started. CONTROL-D will terminate this shell and reboot the system. root@Brown126:~# Control-D just brings me back to the first screen. And nothing works in recovery mode. How can I fix this?

• How to fix 'grub error file not found' when installing 12.04?

  - by Tomasz Grabowski

  i'm trying to install Ubuntu. I don't know if it is important, but i'm trying to install it on external HDD. In the end i have external bootable HDD which only displays: error: file not found grub recovery> From the beginning: I've downloaded ubuntu-12.04-desktop-i386.iso I've used LiLi USB Creator (LinuxLive) to create bootable pendrive from that image I've bootet from it, it works I've clicked "Try ubuntu", it works too. I've used GParted to look over drivers (disks) My primary embedded disk is seen as /dev/sda My attached external disk as /dev/sdb My PenDrive as /dev/sdc I've created partitions on /dev/sdb Fist partition for system (over 200GiB) Second was there already (it's xsf, and i don't want to touch it :P) Third is extended partition, with 1 locital partiton (10GiB) for swap I've started installation i've choose "somethin else" in ... i belive secound screeb then is selected /dev/sdb as boot disk for first partiton of /dev/sdb i set i want ext3 file system, i've check "formattin" checkbox, and mount path set to "/" firs logical partiton set as swap partition After installation finished, i restarted my computer. When i boot from my primary disc it's work ok, my previous operating system - vista - works ok. When i set my BIOS to boot from my external disc, i only get that message: error: file not found grub recovery> I've try to reinstall it, but didn't help... In desperation, i've try to read a bit about that "grub recovery" command-line and experiment a bit... I'm not sure if this has had any point, or if it give you some information (notice, that i don't know what i'm doing :P ) when i've type command: insmod (hd1,1)/boot/grub/linux.mod i've get message: unknown filesystem the same with: insmod (hd1,msdos1)/boot/grub/linux.mod the same with: insmod ext3 but i get no message after command: insmod ext2 ... notice that i really don't know what this command exactly do, but than i thought that maybe if i reinstall ubuntu with ext2 filesystem, it will work. I've done that, but symptoms are the same. I've go back to that Live version of ubuntu, filesystem and basics directories seems to be present on /dev/sdb1 ... i'm completely unfamiliar with GRUB. I'm also don't know which wersion of GRUB it is, i hope there is only one version on ubuntu-12.04-desktop-i386.iso Any help? Thax

• Google Chrome Won't Open

  - by Mike Strand

  When I try to open Google Chrome from the launcher, nothing seems to happen. (this is a new phenomenon, it used to work). I'm on Ubuntu 13.04. When I try to open via the terminal with either $ google-chrome $ google-chrome --incognito I get, ":FATAL:zygote_host_impl_linux.cc(138)] The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I'm aborting now. You need to make sure that /opt/google/chrome/chrome-sandbox is owned by root and has mode 4755." Any help would be appreciated.

• Referencing a picture in another DLL in Silverlight and Windows Phone 7

  - by Laurent Bugnion

  This one has burned me a few times, so here is how it works for future reference: Usually, when I add an Image control into a Silverlight application, and the picture it shows is local (as opposed to loaded from the web), I set the picture’s Build Action to Content, and the Copy to Output Directory to Copy if Newer. What the compiler does then is to copy the picture to the bin\Debug folder, and then to pack it into the XAP file. In XAML, the syntax to refer to this local picture is: <Image Source="/Images/mypicture.jpg" Width="100" Height="100" /> And in C#: return new BitmapImage(new Uri( "/Images/mypicture.jpg", UriKind.Relative)); One of the features of Silverlight is to allow referencing content (pictures, resource dictionaries, sound files, movies etc…) located in a DLL directly. This is very handy because just by using the right syntax in the URI, you can do this in XAML directly, for example with: <Image Source="/MyApplication;component/Images/mypicture.jpg" Width="100" Height="100" /> In C#, this becomes: return new BitmapImage(new Uri( "/MyApplication;component/Images/mypicture.jpg", UriKind.Relative)); Side note: This kind of URI is called a pack URI and they have been around since the early days of WPF. There is a good tutorial about pack URIs on MSDN. Even though it refers to WPF, it also applies to Silverlight Side note 2: With the Build Action set to Content, you can rename the XAP file to ZIP, extract all the files, change the picture (but keep the same name), rezip the whole thing and rename again to XAP. This is not possible if the picture is embedded in an assembly! So what’s the catch? Well the catch is that this does not work if you set the Build Action to Content. It’s actually pretty simple to explain: The pack URI above tells the Silverlight runtime to look within an assembly named MyOtherAssembly for a file named MyPicture.jpg in the Images folder. If the file is included as Content, however, it is not in the assembly. Silverlight does not find it, and silently returns nothing. The image is not displayed. And the fix? The fix, for class libraries, is to set the Build Action to Resource. With this, the picture will gets packed into the DLL itself. Of course, this will increase the size of the DLL, and any change to the picture will require recompiling the class library, which is not ideal. But in the cases where you want to distribute pictures (icons etc) together with a plug-in assembly, well, this is a good way to have everything in the same place Happy coding, Laurent   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

• Using env variables with RewriteRule and ErrorDocument

  - by misterte

  Hi, I'm having problems with the following while config. my Apache server to Rewrite some urls. SetEnv PATH_TO_DIR /directory RewriteRule ^%{PATH_TO_DIR}/([a-zA-Z0-9_\-]+)/([a-zA-Z0-9_\-\.]+)/?$ /index.php?dir=$1&file=$2 ErrorDocument 404 %{PATH_TO_DIR}/index.php?dir=null&file=error This conf. used to work perfectly fine until I used SetEnv PATH... etc. I need to use this because there are lots of rules, not just those. Can anyone point out my mistake? Apache returns %{PATH_TO_DIR}/index.php?dir=null&file=error when I try anything (www.site.com/foo/bar for instance). Apache returns the ErrorDocument if i just try to fetch the index. I know it's not a problem with the rewrite rules because they work when I remove the PATH_TO_DIR variable and just hard code it. Thanks! A.

It has wiped windows from my hard drive already, so I cant go back to the horrible 7 starter edition that came with this netbook.

No idea if I will be able to download an older version and try again from here or what to do... Any help would be great.

• Can't copy from hfs+ external

  - by Janine

  I've spent days and days trying to figure this out, but still can't. I think I've read every article on this and tried all there is to try, and I still can't copy any file from my mac-formatted hfs+ external drive. Sorry if there's still an article I've missed.. I have disabled journaling and tried all the hfsprogs commands I could find, but still whenever I click on a folder on the external and try to copy it to my home directory, I get this: "The folder xxx cannot be handled because you don't have permission to read its content." I then found an article about inoring this by copying files through the Terminal. When trying to run the sudo cp -r command in the Terminal with my external drive path, I always get 'no such file or directory'.. Does anyone have another suggestion for me? Thanks in advance!

• Ubuntu 14.04LTS - runtime video card configuration through Radeon driver

  - by RJVB

  How does one configure Radeon video cards when using the open source Radeon driver - power profile, vsync, etc? Why I try the widely documented solution (against overheating) that worked for me under LMDE (confirmed with kernels up to 3.12.6), I get the following error: $ sudo cat /sys/class/drm/card0/device/power_profile default $ sudo sh -c "echo mid > /sys/class/drm/card0/device/power_profile" sh: echo: I/O error Exit 1 And when I try suggestions from Arch's ATI wiki my modifications are simply ignored: $ sudo cat /sys/class/drm/card0/device/power_dpm_force_performance_level auto $ sudo sh -c "echo high> /sys/class/drm/card0/device/power_dpm_force_performance_level" $ sudo cat /sys/class/drm/card0/device/power_dpm_force_performance_level auto Is this something Ubuntu specific, or something introduced with the 3.13 version of the Radeon driver? I'm encountering this on 2 laptops, one with a Radeon HD6290 (integrated GPU), the other with a discrete RV710 card. The RV710 needs a specific power setting to prevent overheating under LMDE, fortunately it doesn't seem to overheat with the Ubuntu default setting.

• Design for future changes or solve the problem at hand.

  - by Naveen

  While writing the code or during design do you try to generalize the problem at the first instance itself or try to solve that very specific problem. I am asking this because, trying to generalize the problem tends to complicate the things (which may not be necessary) and on the otherhand it will be very difficult to extend the specific solution if there is a change in the requirement. I guess the solution is to find the middle path which is easier said than done. How do you tackle this type of problem ? If you start generalizing it at what point of time you know that this much of generalization is sufficient ?

• Linux Distributive With Global Menu and UbuntuOne For Netbook

  - by Draco Ater

  I like very much global menu in previous versions of Ubuntu. But Unity is too slow for my Eee PC. So now I am looking for some alternative Desktop Environments or Distributions where there is global menu available. But at the same time there should be UbuntuOne service working too, as I use it pretty often. Could you, please, suggest what should I try out? I also use keyboard shortcuts very much and so I guess they should be configurable, and try not to use touchpad at all. So big icons like in gnome-shell and Unity are not a good option.

• What does intermittent "Input/output error" suggest?

  - by dan

  Lately my Ubuntu 12 system has started acting very strange. Sometimes the computer freezes and then unfreezes 2 minutes later, and other times when I try a basic command like less I get the error bash: /usr/bin/less: Input/output error. But this is intermittent too. Any suggestions? Also if I try sudo reboot and enter my password, I get sudo: unable to open /var/lib/sudo/plato/7: Read-only file system Before I used to be able to do sudo reboot fine. If I tail /var/log/syslog I do see these curious lines: .... ata1: softreset failed (device not ready) .... ata1: hard resettting link .... ata1: link is slow to respond, please be patient (ready=0) What can I do to fix this?

• Uploading or attaching files that located on a shared drive doesn't work?

  - by Alex

  I have this odd, quite minor, but annoying issue that I am quite perplexed about. Whenever I try to upload a file via my browser(let's say attach a file to an email in GMail), I click 'Browse' button and it opens standard file selection dialog, that doesn't show network drives. Further more if I try to drag a file from a network drive into GMail, it doesn't work either, it just doesn't let me do that. This issue has been around for quite sometime now, and I am just curious if this is something on my side or if it's a bug or a misconfiguration of some sort. FWIW, I am currently running 10.10, network drive is a samba share on NAS. This happens in FF and Chrome and this is only happens with Samba mounts. As a matter of fact, NFS volumes that are located on the same network operate perfectly fine.

• What would you do if your client required you not to use object-oriented programming?

  - by gunbuster363

  Would you try to persuade your client that using object-oriented programming is much cleaner? Or would you try to follow what he required and give him crappy code? Now I am writing a program to simulate the activity of ants in a grid. The ant can move around, pick up things and drop things. The problem is while the action of the ants and the positions of each ant can be tracked by class attributes easily (and we can easily create many instances of such ants) my client said that since he has a background in functional programming he would like the simulation to be made using functional programming.

• How do I mount my External HDD with filesystem type errors?

  - by Snuggie

  I am a relatively new Ubuntu user and I am having some difficulty mounting my external 2TB HDD. When I first installed Linux my external HDD was working just fine, however, it has stopped working and I have a lot of important files on there that I need. Before my HDD would automatically mount and no worries. Now, however, it doesn't automatically mount and when I try to manually mount it I keep running into filesystem type errors that I can't seem to get past. Below are images that depict my step by step process of how I am trying to mount my HDD along with the errors I am receiving. If anybody has any idea what I am doing wrong or how to correct the issue I would greatly appreciate it. Step 1) Ensure the computer recognizes my external HDD. pj@PJ:~$ dmesg ...
