• How to set up Google Chrome as default browser in Xubuntu

  - by mpm

  I use Xubuntu 12.04. I uninstalled Firefox and now use Google Chrome version 19.xxx. To solve this problem, I tried: galternatives the "default apps" under settings and sudo update-alternatives --config x-www-browser Neither of these worked. Does anybody have an alternative solution for this? -- Solution: I used the "sudo gedit /usr/share/applications/defaults.list" tip from ??? and searched for firefox in the whole document! Everytime I found "firefox" I replaced it with "google-chrome.desktop". I also used the "default apps" menu to change it to google-chrome. And now it works.. I hope it helps some other ;-)

• Xubuntu fails to stay awake when the machine is under load

  - by Alex

  I have the following problem with a fresh install of Xubuntu 12.04: I set up power management options so as to send the machine to sleep after it's been idle for a while. My intention was to have it finish some lengthy numbercrunching and then fall asleep late at night when nobody's present to shut it down. What actually happened, however, is that the machine goes to sleep whenever the desktop session has been idle for the specified amount of time, and it does not seem to care at all about CPU load, and I had to disable sleep altogether. Is there any way to fix this?

• Xubuntu and other Debian based distros slow

  - by William V

  I have a Compaq Presario SR1950NX desktop computer with the AMD64 3800+ processor and 1GB ram and it seems that Ubunutu, Xubuntu and Lubuntu are all laggy. Things seem to be slow such as clicking on menus and opening programs and the UI renders in peices. When using the browser the system slows down considerably. I ran the TOP command and I do notice that xorg hits 30 to 40 percent cpu when running the browsers. I have tried these distros on a spare P4 machine and it is even worse. As long as I don't have a several things open at one time I can manage to get around although sluggishly. I also notice that I can't get debian based distros to install in 64bit (crtc6 failure) only in 32bit. Can anyone tell me what is it that I might be doing wrong? I have an integrated Nvidia card and have tried several of the recommended drivers which sometimes result in no boot screen upon reboot. Thanks

• xubuntu 12.04 restarts after suspend - only from my account

  - by Yoav Aner

  After installing a clean xubuntu 12.04 I noticed that when I suspend, the computer suspends and turns itself off (you see the lights go off, and a click sound from the HD or fans), but then about 2 seconds later it turns itself back on again... The odd thing is that: It doesn't happen when booting from the liveCD I created another user account. When I log onto this account I can suspend fine. The computer stays off until I press the ON button When I remove my .config folder and it's clean - I can also suspend without problem on my account So it seems that something in my user config is causing this, but I can't work out what it might be. I tried diffing the two .config folders, and also all processes running with one account compared to the other (ps -ef |grep <username>), but couldn't find anything obvious that might be causing this...

• xubuntu keyboard application shortcuts not working

  - by Guanidene

  I am using the latest Xubuntu 13.04 with Xfce 4.10. I have issues while setting "Application Shortucts' from 'Settings Manager Keyboard Application Shortcuts'. Not all custom keyboards shortcuts, which I have added, work. Some do, some don't. Example the command 'xdotool key XF86AudioPause' works perfect from cmdline, but not when I assign this as a shortcut to some key, say 'F11'. Have tried to Google about this, but found nothing. Kindly help. If possible, kindly provide me a cmdline way to set a keyboard shortcut

• Xubuntu loading slow after the session/password select

  - by Bryan

  I recently installed Xubuntu on my computer. I love the distro. Everything was fast, and then the bootup slowed down. It started taking a couple minutes for my user selected wallpaper to show and the menu to appear, basically do anything on the comp. I do not recall doing anything other than changing the swappiness. It did not affect it initially. Would that be something to affect it or are there other ideas that might have caused this sudden change.

• Xubuntu - Apps Become Unresponsive Intermittently

  - by Levinaris

  Possibly Relevant Information: XUbuntu 12.04 LTS (precise) XFCE 4.8 AMD Graphics (Kernel driver in use: fglrx_pci, Kernel modules: fglrx, radeon) The primary symptom of this issue has been my active rdesktop session to stop responding while everything else appears to work normally. I have been killing rdesktop and re-launching it, with it freezing after a seemingly random time period. The fastest was within seconds. The longest was a couple hours, although it's usually within a few minutes. That being said, I have occasionally seen the terminal and web browsers also become unresponsive to keyboard input. They respond to clicks and will accept middle clicks (to paste text) without issue while remaining unresponsive to the keyboard input. I have been able to restore all functionality, including rdesktop, by switching workspaces and typing on the other workspace, then returning to the original workspace. What is being reset when I do this? What does this work-around/solution indicate may be the problem?

• Libreoffice theme integration not working (Xubuntu)

  - by Treepata

  I am running Xubuntu 11.10 and everything works nicely. I have selected a nice Xfce theme and everything looks beautiful, except Libreoffice. While other programmes (Gimp, Inkscape, Thunar etc.) integrate with the selected Appearance & Window Manager theme, Libreoffice looks like a Windows 98 programme. Does anyone know how to fix this? I have already tried this solution, without success: http://ubuntuforums.org/showthread.php?t=1584010&page=2 Thanks for your help!

• About Solaris 11 and UltraSPARC II/III/IV/IV+

  - by nospam(at)example.com (Joerg Moellenkamp)

  I know that I will get the usual amount of comments like "Oh, Jörg ? you can't be negative about Oracle" for this article. However as usual I want to explain the logic behind my reasoning. Yes ? I know that there is a lot of UltraSPARC III, IV and IV+ gear out there. But there are some very basic questions: Does your application you are currently running on this gear stops running just because you can't run Solaris 11 on it? What is the need to upgrade a system already in production to Solaris 11? I have the impression, that some people think that the systems get useless in the moment Oracle releases Solaris 11. I know that Sun sold UltraSPARC IV+ systems until 2009. The Sun SF490 introduced 2004 for example, that was a Sun SF480 with UltraSPARC IV and later with UltraSPARC IV+. And yes, Sun made some speedbumps. At that time the systems of the UltraSPARC III to IV+ generations were supported on Solaris 8, on Solaris 9 and on Solaris 10. However from my perspective we sold them to customers, which weren't able to migrate to Solaris 10 because they used applications not supported on Solaris 9 or who just didn't wanted to migrate to Solaris 10. Believe it or not ? I personally know two customers that migrated core systems to Solaris 10 in ? well 2008/9. This was especially true when the M3000 was announced in 2008 when it closed the darned single socket gap. It may be different at you site, however that's what I remember about that time when talking with customers. At first: Just because there is no Solaris 11 for UltraSPARC III, IV and IV+, it doesn't mean that Solaris 10 will go away anytime soon. I just want to point you to "Expect Lifetime Support - Hardware and Operating Systems". It states about Premier Support:Maintenance and software upgrades are included for Oracle operating systems and Oracle VM for a minimum of eight years from the general availability date.GA for Solaris 10 was in 2005. Plus 8 years ? 2013 ? at minimum. Then you can still opt for 3 years of "Extended Support" ? 2016 ? at minimum. 2016 your systems purchased in 2009 are 7 years old. Even on systems purchased at the very end of the lifetime of that system generation. That are the rules as written in the linked document. I said minimum The actual dates are even further in the future: Premier Support for Solaris 10 ends in 2015, Extended support ends 2018. Sustaining support ? indefinite. You will find this in the document "Oracle Lifetime Support Policy: Oracle Hardware and Operating Systems".So I don't understand when some people write, that Oracle is less protective about hardware investments than Sun. And for hardware it's the same as with Sun: Service 5 years after EOL as part of Premier Support. I would like to write about a different perspective as well: I have to be a little cautious here, because this is going in the roadmap area, so I will mention the public sources here: John Fowler told last year that we have to expect at at least 3x the single thread performance of T3 for T4. We have 8 cores in T4, as stated by Rick Hetherington. Let's assume for a moment that a T4 core will have the performance of a UltraSPARC core (just to simplify math and not to disclosing anything about the performance, all existing SPARC cores are considered equal). So given this pieces of information, you could consolidate 8 V215, 4 or 8 V245, 2 full blown V445,2 full blown 490, 2 full blown M3000 on a single T4 SPARC processor. The Fowler roadmap prezo talked about 4-socket systems with T4. So 32 V215, 16 to 8 V245, 8 fullblown V445, 8 full blown V490, 8 full blown M3000 in a system image. I think you get the idea. That said, most of the systems we are talking about have already amortized and perhaps it's just time to invest in new systems to yield other advantages like reduced space consumptions, like reduced power consumption, like some of the neat features sun4v gives you, and yes ? reduced number of processor licenses for Oracle and less money for Oracle HW/SW support. As much as I dislike it myself that my own UltraSPARC III and UltraSPARC II based systems won't run on Solaris 11 (and I have quite a few of them in my personal lab), I really think that the impact on production environments will be much less than most people think now. By the way: The reason for this move is a quite significant new feature. I will tell you that it was this feature, when it's out. I assume, telling just a word more could lead to much more time to blog.

• TDE Tablespace Encryption 11.2.0.1 Certified with EBS 12

  - by Steven Chan

  Oracle Advanced Security is an optional licenced Oracle 11g Database add-on.  Oracle Advanced Security Transparent Data Encryption (TDE) offers two different features:  column encryption and tablespace encryption.  11.2.0.1 TDE Column encryption was certified with E-Business Suite 12 as part of our overall 11.2.0.1 database certification.  As of today, 11.2.0.1 TDE Tablespace encryption is now certified with Oracle E-Business Suite Release 12. What is Transparent Data Encryption (TDE) ? Oracle Advanced Security Transparent Data Encryption (TDE) allows you to protect data at rest. TDE helps address privacy and PCI requirements by encrypting personally identifiable information (PII) such as Social Security numbers and credit card numbers. TDE is completely transparent to existing applications with no triggers, views or other application changes required. Data is transparently encrypted when written to disk and transparently decrypted after an application user has successfully authenticated and passed all authorization checks. Authorization checks include verifying the user has the necessary select and update privileges on the application table and checking Database Vault, Label Security and Virtual Private Database enforcement policies.

• Upgrade to 11.2.0.3 - OCM: ORA-12012 and ORA-29280

  - by Mike Dietrich

  OCM is the Oracle Configuration Manager, a tool to proactively monitor your Oracle environment to provide this information to Oracle Software Support. As OCM is installed by default in many databases but is some sort of independent from the database's version you won't expect any issues during or after a database upgrade But after the upgrade from Oracle 11.1.0.7 to Oracle 11.2.0.3 on Exadata X2-2 one of my customers found the following error in the alert.log every 24 hours: Errors in file /opt/oracle/diag/rdbms/db/trace/db_j001_26027.trc: ORA-12012: error on auto execute of job "ORACLE_OCM"."MGMT_CONFIG_JOB_2_1" ORA-29280: invalid directory path ORA-06512: at "ORACLE_OCM.MGMT_DB_LL_METRICS", line 2436 ORA-06512: at line 1 Why is that happening and how to solve that issue now? OCM is trying to write to a local directory which does not exist. Besides that the OCM version delivered with Oracle Database Patch Set 11.2.0.3 is older than the newest available OCM Collector 10.3.7 - the one which has that issue fixed. So you'll either drop OCM completely if you won't use it: SQL> drop user ORACLE_OCM cascade; or you'll disable the collector jobs: SQL> exec dbms_scheduler.disable('ORACLE_OCM.MGMT_CONFIG_JOB');SQL> exec dbms_scheduler.disable('ORACLE_OCM.MGMT_STATS_CONFIG_JOB'); or you'll have to reconfigure OCM - and please see MOS Note:1453959.1 for a detailed description how to do that - it's basically executing the script ORACLE_HOME/ccr/admin/scripts/installCCRSQL - but there maybe other things to consider especially in a RAC environment. - Mike

• Keyboard / keymap problems with Xubuntu 12.04 + NX nomachine

  - by bajafresh4life

  I'm running NX client on my Macbook Pro to connect to a Xubuntu 12.04 desktop at work. I have configured NX client to start up a console upon connection. I am able to connect to my remote linux machine and I get a simple xterm console. However, when I run xfce4-session, half my keys no longer work. For example, when I launch a terminal, I typing a, s, or d works, but if type w, e, r, or t, the cursor just blinks. If I ctrl-C out of xfce4-session, all the keys work fine in my xterm console. If I run xev, this is the output for when I hit a key that works: KeyRelease event, serial 34, synthetic NO, window 0x2e00001, root 0x373, subw 0x0, time 170160781, (-45,-21), root:(824,429), state 0x4, keycode 16 (keysym 0x63, c), same_screen YES, XLookupString gives 1 bytes: (03) "" XFilterEvent returns: False KeyRelease event, serial 34, synthetic NO, window 0x2e00001, root 0x373, subw 0x0, time 170160781, (-45,-21), root:(824,429), state 0x4, keycode 67 (keysym 0xffe3, Control_L), same_screen YES, XKeysymToKeycode returns keycode: 63 XLookupString gives 0 bytes: XFilterEvent returns: False but when I hit a key that doesn't work: FocusOut event, serial 34, synthetic NO, window 0x2e00001, mode NotifyGrab, detail NotifyAncestor FocusIn event, serial 34, synthetic NO, window 0x2e00001, mode NotifyUngrab, detail NotifyAncestor KeymapNotify event, serial 34, synthetic NO, window 0x0, keys: 2 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Any ideas on what I can do to troubleshoot this issue? Googling around offered a few suggestions (like playing with xmodmap) but nothing seemed to work. Also, one thing worth mentioning is that I do not have any keyboard issues when remoting into a different Ubuntu 10 box via NX.

• Not Happy With the Monochrome Visual Studio 11 Beta UI

  - by Ken Cox [MVP]

  I can’t wait for a third-party to come out with tools to return some colour to the flat, monochrome look of Visual Studio 11 (beta). What bugs me most are the icons. I feel like a newbie when I have to squint and analyze the shape of icons on the debugging toolbar just to get the one I want. (Fortunately, the meddlers didn’t mess with the keyboard commands so I’m not totally lost.) Not sure what usability studies told MS that bland is better. Maybe it is for most people, but not for me.  Gray, shades of gray and black. Ugh. And don’t get me started on the stupidity of using all-caps for window titles. Who approved that? I see that there’s a UserVoice poll on the topic (http://visualstudio.uservoice.com/forums/121579-visual-studio/suggestions/2623017-add-some-color-to-visual-studio-11-beta) but I doubt that anything will change Microsoft’s opinion in time for the release. Once a product gets to a stable beta, most non-crashing stuff gets pushed to the next version. I hope I’m proved wrong. Fortunately, Visual Studio is quite customizable. Unless ‘Bland’ is hard-coded, some registry tweaks and a collection of replacement icons should allow dissenters like me back to productivity. BTW, other than hating the UI, VS 11 beta is working quite well for me on a .NET 4 project.Note: Although my username for the ASP.NET domain includes the letters "[MVP]", I'm no longer an MVP. Apparently it's nearly impossible to change a username in the system. My apologies for the misleading identifier but I tried to have it changed without success.

• Oracle E-Business Suite Release 12.1 Certified on Solaris 11

  - by John Abraham

  Oracle Solaris 11 was announced last week, and I'm pleased to also announce that Oracle E-Business Suite Release 12.1 is now certified on Oracle Solaris on SPARC (64-bit). This new operating system release represents a culmination of years of hard work by our Solaris engineering group.  It has a number of new and advanced features including simplified deployment and lifecycle management tools, built-in certified virtualization technologies, support on the latest generation SPARC chips, and more. New installations of the E-Business Suite R12 on this platform will require version 12.1.1 or higher and the latest Rapid Install startCD version 12.1.1.13.  For existing 12.1 installations, we have also certified an "in place" OS upgrade or the use of cloning to a target Solaris 11 system. There are also specific requirements to upgrade technology components such as the Oracle Database and Fusion Middleware.  These requirements are noted in the links below. References Oracle E-Business Suite Installation and Upgrade Notes Release 12 (12.1.1) for Oracle Solaris on SPARC (64-bit) (My Oracle Support Document 761568.1) Oracle Database Installation Guide 11g Release 2 (11.2) for Oracle Solaris Interoperability Notes Oracle E-Business Suite Release 12 with Oracle Database 11g Release 2 (11.2.0) (My Oracle Support Document 1058763.1) Cloning Oracle Applications Release 12 with Rapid Clone (My Oracle Support Document 406982.1) Related Articles New Rapid Install StartCD (12.1.1.13) for Oracle E-Business Suite Release 12.1 Now Available Oracle E-Business Suite Release 12.1.3 Now Available

• Change power button to 'Ask' in Xubuntu 13.10

  - by Gully.Moy

  I have recently installed Xubuntu 13.10 on my Vaio vpcea making me a Linux beginner. The problem is that laptop's power button is right on the edge of the bezel making it far too easy to press accidentally, in my opinion a design fault by Sony. At present, when I press the power button it shuts down strait away and as you can imagine, when I'm accidentally pressing it all the time it gets very annoying! So I planned to change it to ask what I would like to do when I press it or at least ask if I'm sure. So I went through the xfce GUI options "Settings Manager" - "Power Manager" to the field "When power button is pressed", but it was already set to "Ask". So I did some digging and found a thread telling me to navigate to /etc/xdg/xfce4/xfconf/xfce-perchannel-xml/xfce4-power-manager.xml where it said to find power-button-action and check that value="3". It already did. So I looked some more and found this thread which focuses on acpi scripts. I tried solution 1 & 2 using sudoedit to change the files accordingly (I have made executable bash shell scripts already so I think I followed them correctly), but still no difference. I also found this thread which instructed me to edit /etc/systemd/logind.conf so that HandlePowerKey=ignore. Still no luck. I even tried my own approach to completely disable /etc/acpi/powerbtn.sh by renaming it powerbtn.sh.bak hoping for at least no response from the power button... and I have done many reboots in between... but still it shuts down! I have also read that some people have the file /etc/acpi/events/power_button, but I do not. So does anyone have any other ideas? What else could be executing the shutdown sequence Is there something I'm missing? I haven't undone any of these actions so every one of the above files is currently edited on my computer, with the exception that "Solution 2" automatically undone "Solution 1" above. Thanks guys.

• .NET Demon support for VS 11 dark theme

  - by Alex.Davies

  I'm pleased to announce that .NET Demon will be shipping simultaneously with Visual Studio 11, whenever it ends up being released. That means we're going to make sure that a version of .NET Demon is released very near to the Visual Studio 11 final release which supports the new version of VS fully. The interesting part of this support is going to be the new dark theme of VS, which I'm looking forward to using. I'm told dark colours reduce eye strain for developers. It's important that extensions like .NET Demon switch to a dark theme when the rest of the IDE changes, or the dark theme will look silly. Unfortunately, none of my favourite extensions look right in the dark theme yet, so even though I use Visual Studio 11 beta for my day-to-day development already, I can't use the dark theme. Luckily .NET Demon uses WPF throughout, and the team at Microsoft are helping us to use the WPF Style system to make it easy for me to implement the support without having to add colour attributes to all the controls manually. We should have dark theme support in .NET Demon in the next month or so.
