• Chrome window controls in xubuntu 12.04

  - by Norbert

  I'm a long time ubuntu 10.04 LTS user, very used to having window controls on top left borders. New computer with new video card requires newer kernel. Unity doesn't suit and much googling turned up recommendations for xubuntu. Installed 12.04 and first aggravation is window controls at upper right a la Windows. No problem ... Settings Manager - Windows Manager - rearrange button layout Fixes everything until ... I abandoned firefox long ago because of memory leak issues and general fat. I fetch a current version of chrome (19.0.1084.52) and install. Once adblock is added and it's the default browser, everything's great. Except ... Alone among all applications, chrome will not honour the window manager's preferred button layout. Buttons are at upper right no matter what I try. Uninstall and then reinstall: nope. Trawl through /home/user/.config/google-chrome/* looking for a likely setting: nope. Search the web: nothing useful. How do I get chrome's window decoration in sync? Thanks very much for any and all help.

• Dark screen when wake / Unable to control screen brightness

  - by John

  Running Ubuntu 11.04 on Lenovo ThinkPad with an Nvida graphics card. The unit goes to sleep when the lid is shut. (The unit goes to suspend mode (not to disk/hibernate), AC gets turned off, running on battery) Upon lid-open sometimes the screen is almost too dark to read. I'm really not sure of the exact cause, (very low batt??). The only fix is a reboot. The screen brightness buttons have never worked in Ubuntu. I have messed w/ the power management preferences. No change. At one point I messed w/ the gnome settings. No change. I have tried a few cmds: echo 9>/sys/class/backlight/acpi_video0/brightness setpci -s 00:02.0 F4.B=10 xgamma -gamma .75 None of these help. Most have zero effect. I think it is and acpi thing, but that is just a guess. I'm out of idea's, and looking for suggestions. Thanks

• Cannot see boot options after editing grub background

  - by cipricus

  After solving this problem I managed to get myself into truble again out of nothing by trying to change the display of the dual boot option page in Boot Customizer. I have changed the background, the fonts size (I have increased them) and font style (I have chosen UnDotum). But Boot Customizer gave me an error (I mean a message that the application was closed unexpectedly or smth). I have restarted BootCustomizer and the settings were there. When I rebooted, instead of the normal boot options list, just the background image that I had selected and nothing else. I used Boot Repair to repair grub, it says it did it successfully, but I still get the background image when I try to boot. Any ideas? (Could it be the matter that I chose UnDotum font style? That was installed in Lubuntu - but how could it be accessible in displaying boot options?) The contents of etc/default/grub are: # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX="" # Uncomment to enable BadRAM filtering, modify to suit your needs # This works with Linux (no patch required) and with any kernel that obtains # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef" # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE=640x480 # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID=true # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1" I have tried to modify etc/default/grub: GRUB_HIDDEN_TIMEOUT=0 to 10 GRUB_HIDDEN_TIMEOUT_QUIET=true to false and GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to "" but it doesn't help Also, using Shift doesn't make the list visible.

• Why is wireless slow with Atheros AR9285?

• Nvidia dual monitor configuration gets lost every time I reboot

  - by sunwukung

  I've recently updated (well, borked then completely reinstalled) to 12.04. I'm running a dual monitor setup, with a Dell U2410 / Dell 2007WFP combination on an HP Elite Book 8560W. The graphics card is an NVIDIA GF108 [Quadro 1000M]. My problem is as follows. I can get the dual monitor setup working fine, but every time I reboot, my machine appears to lose the settings (specifically, the U2410 is disabled, the mouse pointer is locked in the launcher). I have to restate the settings after every launch. I've tried running nvidia-settings as sudo, I've save the changes to my xorg.conf file (see below) but nothing seems to be sticking. Has anyone had similair issues, or know of a fix? Conf file follows: # nvidia-settings: X configuration file generated by nvidia-settings # nvidia-settings: version 295.33 (buildd@allspice) Fri Mar 30 15:25:24 UTC 2012 Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" 0 0 InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" Option "Xinerama" "0" EndSection Section "Files" EndSection Section "InputDevice" # generated from default Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" # generated from default Identifier "Keyboard0" Driver "kbd" EndSection Section "Monitor" # HorizSync source: edid, VertRefresh source: edid Identifier "Monitor0" VendorName "Unknown" ModelName "DELL 2007WFP" HorizSync 30.0 - 83.0 VertRefresh 56.0 - 76.0 Option "DPMS" EndSection Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "Quadro 1000M" EndSection Section "Screen" Identifier "Screen0" Device "Device0" Monitor "Monitor0" DefaultDepth 24 Option "TwinView" "1" Option "TwinViewXineramaInfoOrder" "DFP-1" Option "metamodes" "CRT: 1680x1050 +1920+0, DFP-1: 1920x1200 +0+0; CRT: nvidia-auto-select +0+0, DFP-1: NULL" SubSection "Display" Depth 24 EndSubSection EndSection The error message I'm getting is this: none of the selected modes were compatible with the possible modes: Trying modes for CRTC 642: CRTC 642: trying mode 3600x1080@50hz with output at 1280 x 1024@0Hz (pass 0) CRTC 642: trying mode 3600x1080@50hz with output at 1280 x 1024@0Hz (pass 0) CRTC 642: trying mode 3600x1080@50hz with output at 1280 x 1024@0Hz (pass 0) CRTC 642: trying mode 3600x1080@50hz with output at 1280 x 1024@0Hz (pass 1) CRTC 642: trying mode 3600x1080@50hz with output at 1280 x 1024@0Hz (pass 1) CRTC 642: trying mode 3600x1080@50hz with output at 1280 x 1024@0Hz (pass 1)

• Skype sounds sizzle/distorted/bad

  - by Filubuntu

  I have the same problem as described in the questions skype notification sounds sizzled and bad sound on login to skype. But it is not only the login, notification, but also when talking to somebody. I tried the solution to remove/re-install skype and most of the solutions in this questions, e.g. checking mixer, sound settings and installing alsa-hda-dkms (incl. system restart). After installing skype (and even after upgrade to skype 4.0) in Ubuntu 12.04 (AMD 64) there was no sound at all. I followed the first step of the SoundTroubleshootingProcedure and at least there is now sound: sudo add-apt-repository ppa:ubuntu-audio-dev/ppa; sudo apt-get update;sudo apt-get dist-upgrade; sudo apt-get install linux-sound-base alsa-base alsa-utils gdm ubuntu-desktop linux-image-`uname -r` libasound2; sudo apt-get -y --reinstall install linux-sound-base alsa-base alsa-utils gdm ubuntu-desktop linux-image-`uname -r` libasound2; killall pulseaudio; rm -r ~/.pulse*; sudo usermod -aG `cat /etc/group | grep -e '^pulse:' -e '^audio:' -e '^pulse-access:' -e '^pulse-rt:' -e '^video:' | awk -F: '{print $1}' | tr '\n' ',' | sed 's:,$::g'` `whoami` The jittering sound would sometimes disappear, e.g. on the Echo-Testcall after replaying the recorded part. And I noticed that if I let music play in the rhythmbox and then start skype, the sound is fine. So I have a weak solution, but I would be glad it would work without this detour. As requested: My sound card is a an "AMD High Definition Audio Device" called Advanced Micro Devices (AMD) Hudson Azalia controller (rev01), subsystem Lenovo Device 21ea (according to sysinfo) on a Lenovo Thinkpad Edge 525.

• Microsoft Tag Tagged Me

  - by Brian Schroer

  I got EXTREMELY lucky last week and won an HP Mini 311 notebook from a Microsoft Tag Twitter contest. I did my required tweet to enter last Tuesday, and one hour later received notification that I had won the weekly drawing. Apparently you can tweet up to 500 times (I pity the followers of those who do that), so it was really lucky that I won, and I sympathize with those who had been really trying. If you would like to try your luck, there are seven weekly prizes left, and you can find out about the contest here: http://tag.microsoft.com/ttcontest.aspx For a free PC, I thought it was the least I could do to find out what Microsoft Tag is. I was vaguely aware of those pastel-y triangle-y square things that look like someone put one of Don Johnson’s Miami Vice outfits through a shredder, and knew that the company I work for (one of the world’s largest consumer products companies) was looking into putting them on our products, packaging and advertising, but didn’t know much more about the technology. I thought they were just an improvement over bar codes, and would be used in retail store scanners, but I was mistaken. These tags are meant to be scanned by consumers using their mobile phones, to get instant access to information, websites, reviews, etc. Scanning a tag can open a web page, import a contact card, or dial a phone number, play a video… Tag reader software can be installed on Windows Mobile, iPhone, Symbian, Blackberry, Android, J2ME, and other phones (and I suspect that it will be available for Windows Phone 7 also :). There are built-in tracking, metrics and analysis tools, to help companies using Tag make decisions about their marketing expenditures. (And they don’t have to look Miami Vice-y – They can be customized to reflect the personality of the person or a brand.) Looks like interesting stuff. You can find out more at http://tag.microsoft.com.

• Raid Shows Up as Multiple Drives - Can't Mount

  - by manyxcxi

  I have a single hard drive that the OS is installed on and I have Sil raid card installed with two matching 500GB hdds set up in Raid 0 and formatted- they're completely empty. For whatever reason they are showing up as /dev/sdb and /dev/sdc and not as a single hard drive. I used fdisk to format both raid drives as Linux raid auto (fd) but I cannot mount either device and dmraid doesn't seem to want to work, what step am I missing?

• Galaxy Note II MTP on Ubuntu 12.04

  - by Anass Ahmed

  I bought a branding new Galaxy Note II and I tried to mount its storage to my ubuntu laptop. As you know, Android 4.0+ uses MTP by default. Android 4.1 doesn't support USB Mass Storage anymore!

• 12.04, nvidia-settings makes one of my dual monitors grey and useless, disables network

  - by Kerrick

  I'm running Ubuntu 12.04 64-bit, Precise Pangolin, with a PNY GTS 250 1GB video card and a monitor plugged into each of the DVI ports. I'm using the proprietary drivers (post-release updates). If I set anything to do with Separate X Screens up in nvidia-settings (and write it to xorg.conf and reboot), my second monitor has a grey background, no menu bar, no ability to have a window on it, the second monitor doesn't get picked up in a screneshot, and if I move my mouse cursor to it it's an ugly black X. Plus, my network is unable to connect to anything. If I subsequently delete /etc/X11/xorg.conf and reboot, everything goes back to working, albeit with a single monitor activated. If I set anything to do with TwinView up in nvidia-settings, my second monitor starts working, but it isn't seen as a second monitor by Ubuntu, so I can't apply color calibration to it separately. Plus, my mouse gets "caught" between the monitors every time I try to move my cursor between the two. What gives? If it helps, this is the xorg.conf that nvidia-settings generates for Separate X Screens.

• What is the role of traditional issue tracker when Scrum / Kanban board is used?

  - by Borek

  From a very high level view, to me it seems there are generally 2 types of Project Management tools: Traditional issue trackers like Fogbugz, JIRA, BugZilla, Trac, Redmine etc. Virtual card boards / agile project management tools like Pivotal Tracker, GreenHopper, AgileZen, Trello etc. Sure, they overlap in one way or another, e.g. Pivotal Tracker tasks can be imported to JIRA, GreenHopper itself is implemented on top of JIRA issue base etc. but I think one can still see the difference in orientation between those two types of tools. Traditional issue tracker seems to be used even in companies otherwise doing agile project management. My question is, why do they do that? I also feel that we should use an issue tracker in my company but when I'm thinking about it, I'm not actually sure why should we need it. For example, Trello development seems to be managed by using Trello itself (see this virtual wall) even though they have access to Fogbugz, one of the best issue trackers around. So maybe we don't need traditional issue tracker when we'll be doing 100% of our work in an agile manner using one of the agile PM tools?

• Can't connect to or see my wifi ssid

  - by ant

  Today I installed ubuntu 12.04 on my laptop. I am unable to see my home SSID or even connect to it. I've tried to connect as a hidden SSID but I always get prompted for authorization although my key is correct. I'm in in Europe but my laptop is from US. I'm not sure if that is relevant. I've read around this site and saw something that has to do with setting the channel above 11. I'm not sure I did that correctly I did this : How to use Wi-Fi channels above 11? Did't help. I'm able to connect with cable but not via wifi either windows or linux. Other devices in my home can connect without any issues, even the kindle.

• AMD FX CPU drivers/patch

  - by Mubeen Shahid

  I am using Ubuntu since 2009 on notebooks with Intel CPUs. However now, that I am using AMD's FX 6300, I am interested in knowing if there exists anything from Ubuntu (specifically any kernel enhancements/drivers/patches) for AMD's FX "family 15h" Piledrivers. Reason: I would like to have a kernel which uses the hardware to its full capacity, be able to use the latest instruction sets, for max. performance. I did some tests, started with compiling stable 3.9.7 on my 12.04 LTS box, and during compilation I choose processor vendor AMD (unchecked Intel/VIA/etc.), and when I started Ubuntu with this compiled kernel, in the section "System Settings - Additional Drivers" I found that, in addition to graphic card's drivers, there were AMD family 15h drivers also. However, I would prefer something in this regard tested/signed by Ubuntu developers. P.S: 1- the kernel that I have compiled has some issues with Nvidia graphics drivers, so I deleted kernel 3.9.7 and installed signed 3.8.xx from Ubuntu repositories. 2- incase if somebody is planning to advise me to install "AMD64", I am not talking about AMD64 (which is in fact for 64-bit platform).

• Unity Greeter login screen cuts off login options

  - by ammianus

  I have a pretty newly installed Ubuntu 12.04, using Unity. My external monitor is 1920x1080 max resolution. In the Unity desktop itself everything looks great. I have an NVidia graphics card. When I start my computer and get to the Unity greeter login screen the display is oddly formatted and the resolution seems off. It looks like a zoomed view on the larger 1920x1080 screen. As such it crops the login options off to the left hand side of the screen. So I can only just see the edge of the password box for the user I want to log in with. I can log in with one account by default by blindly typing the password, but I am unable to switch to other accounts. Is there anything I can do to fix the log in screen display so that I can see the normal login options? Note: I first noticed it when I changed my desktop background and the next time I logged in I saw the issue.

• Ubuntu 12.04 does not suspend with proprietary driver for Radeon 6800

  - by Mike

  I'm running Ubuntu 12.04 x86_64 (though these issues have existed in previous releases too) and have a Radeon 6800 graphics card. I've run into issues with the open-source driver (the system would randomly hang when shutting down) so I switched to the proprietary driver (I compiled it myself using these instructions), but I am having new problems now. The main issue is that when I go into sleep mode, about 50-75% of the time, the screen goes black but the monitor does not actually shut off, and I can hear that the fans/hard drive are not suspending either. I can't get the computer to wake up (Ctrl+Alt+F1,2,3,etc. does not work), and I always end up force shutting down with the power button. I'd really appreciate help! Here is some information that might be helpful: $ fglrxinfo display: :0 screen: 0 OpenGL vendor string: Advanced Micro Devices, Inc. OpenGL renderer string: AMD Radeon HD 6800 Series OpenGL version string: 4.2.11631 Compatibility Profile Context $ dmesg | grep fglrx [...] [ 6.718606] [fglrx] module loaded - fglrx 8.96.4 [Apr 5 2012] with 1 minors [...]

• Intel graphic chipset and NVIDIA Geforce GTX560

  - by antoine

  I have an NVIDIA Geforce GTX560 with two video projectors and I would like to use the onboard Intel Graphic Chipset to plug an additional monitor. I saw the question : How can I use both Intel onboard and Nvidia graphics at the same time? but the answer is so short that I was not convinced. My motherboard (GIGABYTE GA-H61M-D2P-B3 (rev. 1.0)) equipped with Intel H61 Chipset allow shared memory between onboard and PCIe cards. And Windows 7 allow me to use the three outputs thanks to Intel's driver. I'm able to use the onboard graphic card but without graphical interface for now. I think i need intel driver for that. But I would like to know if I can setup my displays in xorg.conf with something like : Section "Device" Identifier "Device0" Driver "intel" EndSection Section "Device" Identifier "Device1" Driver "nvidia" EndSection Section "Device" Identifier "Device2" Driver "nvidia" EndSection Does anyone have successfully setup something like that ? Or should I burn my head experimenting it by myself ? Or is there any good reasons to discouraged me to try ? Thanks for your help. Antoine PS : i'm using Ubuntu 10.10 for now, but I could switch to another version. PS2 : i also read this : Use 3 monitors w/built-in intel adapter + two old nvidia PCI cards on 10.10? which doesn't tell me more about the possibilities to use Intel Graphic and Nvidia at the same time EDIT : according to that : Can not get Dual Monitors to work on Different GPUs, I should be able to run two Xserver one on Intel the other on Nvidia. I will try and post the result here.

• Blank screen after GRUB (64 bit) - cannot install Ubuntu

  - by peGGi

  My laptop's specs: Lenovo IdeaPad Z570 Intel Core i5-2410M @ 2.3Ghz 6 Gb RAM DDR3 640 Gb ATAPI Hard-disk Drive @ 5,200 RPM NVIDIA GeForce G520M with Optimus switching technology Broadcom 802.11n Network Adapter REALTEK soundcard Windows 7 Home Premium 64-bit I downloaded Ubuntu Studio 11.04 and burned the iso image onto two different DVDs, using two different programs (one DVD is RW, the other is just R). I verified the hash MD5sum thing. I get as far as GRUB with the 4 options (install, advanced install, disk verification, system rescue) but no matter which one I select, I get a blank screen and nothing happens. The DVD drive spins down after about 30 seconds. Also just before the GRUB screen I get a message saying Error: "Prefix" is not set. I'm not sure if that's relevant. I have tried all the options using both DVDs. Same thing happens. I have changed the graphics setting in BIOS to UMA or Optimus, but still happens either way. I've tried booting with the wireless switch turned off, same thing happens. I downloaded 'vanilla' Ubuntu 64-bit and burned onto a CD, and the same thing happens. I have downloaded Ubuntu 32-bit and I am able to boot from the live CD (interestingly the wireless card won't work, but that's maybe another issue). I have searched extensively through these forums and other sites but I can't see anything that will help me. Is there something I'm missing? I'd really appreciate help on this. The laptop is less than 2 weeks old. I was so looking forward to getting Ubuntu Studio up and running. I've gone about as far as my technical abilities will allow.

• MPlayer does not work

• Reverse WiFi to Broadcast connection coming from a USB device

  - by Daniel Clem

  I am using the app called Clockworkmod Tether. It connects using a script ( command line " gksu ./run.sh " ) on the computer. All my programs connect to the internet perfectly, minitube, midori, transmission torrents. But the network manager does not show any connection, wired or wireless. So this may cause issues? What I want to do is take this connection, and be able to share it some way, any way, by wireless. This Acer Timeline "Aspire 5810TZ" does have an Ethernet, so wired out to a router might be an option. But I would prefer to simply reverse the Wireless card to broadcast out to about 2 or 3 devices. Is this possible? Yes I have taken a look at the other questions already posted here, but the answers are 1 year old or older, and not clear at all. I am moderately comfortable (4.5 out of 10 ) on the command line. But pretty much need line by line directions for what commands are needed and what order, ect. Edit I have already tried the method of "Left click network manager, Create New Wireless Network" It is created fine, and I am able to connect to it with a tablet, but am un-able to get an outside connection with it. Using the "Shared to other computers" option because DHCP doesn't seem to work, and WEP Passphrase Security. I get an IP address on the connected device. But as I said, won't bring up any outside webpages or the like. So perhaps this is the wrong approach?

• SQL SERVER – Caption the Cartoon Contest – Last 2 Days

  - by pinaldave

  Developer’s life is very interesting, we often want to start my day early at a job so we can go home early. However, the day never comes as the life of the developer is always about working late hours. If the developer goes to the office early – there are good chances that his co-workers will come late. Additionally, I am confident that there will be always something urgent for developers or DBA to solve right at the time they are ready to go home. This is the life of the developers!  Here is the interesting story of a DBA who was about to go to the home. He had to take his girlfriend to a movie and dinner in 30 minutes. However, his manager asks him to fix the performance related issues with their production server. In normal case, he had only two choices a) Job or b) Girlfriend. Well, our super hero DBA decided to use efficient tools and improve the performance of the production server in merely 30 minutes. When he was done, his manager was absolutely surprised by his efficiency and accuracy of the work. He asked him following question - Here is the contest – you need to guess what was the answer of our Super Hero DBA. If you guess the answer correct you may win Star Wars R2-D2 Inflatable Remote Controlled device. Additionally, if you Download DB Optimizer before Dec 8, 2012 – you will be eligible for USD 25 Amazon Gift Card (there are total 10 such awards).

• Mouse doesn't work & internet connection not made in Ubuntu 12.04 LTS

  - by David Skare

  Yesterday, Nov 15, 2012, I booted into my Ubuntu 12.04 LTS system. It has resided on a Crucial 128 GB SSD with about 90% free space since early summer. I also have Windows 7 loaded on another Crucial 256 GB SSD. Ubuntu has set up a dual boot system for me even though each OS has its own SSD. I have been using this setup without problems since summer. Yesterday, when the boot process finished, my Microsoft Comfort Mouse 3000 did not work and there was a message that Ubuntu was not connected to the internet. So w/o the mouse I was forced to turn the machine off manually. About 4 days ago Ubuntu worked fine and booting into Win 7 also works fine. I have a backup machine with the same style mouse on it so I swapped the mouse onto this system. Same results. But both mice work when booting into Win 7. Today I removed both SSDs and installed my Ubuntu 12.04 HD which has not been used since I moved Ubuntu to the SSD from it. Same results. Between the last time I used Ubuntu 12.04 on the SSD and when I tried to use it again I made no changes to my machine, either hardware or software. My machines specs are: AMD FX-6100, MSI 990FXA-GD65 AM3+ format with latest BIOS (Ver 19.9), Corsair Vengeance 1866 MHz memory - 16 GB (4GB X 4 sticks), MSI N580GTX video card (nVidia 306.97 drivers), Sony Bravia 32" HD TV as a monitor, Pioneer BluRay DVD-RW, DSL connection to internet thru a router (10 mps), Crucial 128 GB SSD (90% free space), Microsoft Comfort Mouse 3000 I try to maintain current BIOS and drivers for all devices. I mostly use my Ubuntu system for programming in GCC and OpenCOBOL, surfing the internet and e-mailing. No games are installed. I'm stumped! If anyone has experienced this same problem I'd appreciate knowing how you solved it. TIA, Dave

• Radeon 9200 Driver?

  - by usuhh86

  I've been using Linux for a while, but haven't really done more than installed programs. I have Ubuntu 12.04 with an ATI Radeon 9200 graphics card. Ubuntu didn't recognize it during the install. All I want is a driver. Preferably the proprietary driver, but I'll settle for an open-source one if I need to. I went to the AMD support website, and whenever I click on the download link for "ATI Proprietary Linux x86 Display Driver 8.28.8" I get redirected to the main AMD website. I tried this on Firefox, Chrome, even booted up my netbook and tried it on IE9. Does anybody have a download link? And if not, a link to download an open-source alternative? Any help will be greatly appreciated. I'm pretty much still a newbie at this. OpenGL vendor string: Tungsten Graphics, Inc.

• nvidia-settings makes one of my dual monitors grey and useless, disables network

  - by Kerrick

  I'm running Ubuntu 12.04 64-bit, Precise Pangolin, with a PNY GTS 250 1GB video card and a monitor plugged into each of the DVI ports. I'm using the proprietary drivers (post-release updates). If I set anything to do with Separate X Screens up in nvidia-settings (and write it to xorg.conf and reboot), my second monitor has a grey background, no menu bar, no ability to have a window on it, the second monitor doesn't get picked up in a screneshot, and if I move my mouse cursor to it it's an ugly black X. Plus, my network is unable to connect to anything. If I subsequently delete /etc/X11/xorg.conf and reboot, everything goes back to working, albeit with a single monitor activated. If I set anything to do with TwinView up in nvidia-settings, my second monitor starts working, but it isn't seen as a second monitor by Ubuntu, so I can't apply color calibration to it separately. Plus, my mouse gets "caught" between the monitors every time I try to move my cursor between the two. What gives? If it helps, this is the xorg.conf that nvidia-settings generates for Separate X Screens.

  - by Mario

  Can't google out the solution through some time so I'm asking here. I have installed Linux Ubuntu 12.04 LTS in virtual box hosted by Windows 7 64bit Simple my 3D stopped working after some kernel headers update<<< few months ago. Just like that. I don't member which version was it. In meantime there was 2 or 3 new releases of VirtualBox which I have installed. Every time I am updating VirtualBox Guest Additions to the newest version. My 3D in Ubuntu still doesn't work. root@pjadmin-VirtualBox:~# /usr/lib/nux/unity_support_test -p OpenGL vendor string: VMware, Inc.

• Using Solaris zfs + iscsi targets with Oracle VM

  - by wim.coekaerts

  I was playing with my Oracle VM setup and needed some shared storage that was block based. I did not have a storage array available but I did have a solaris box, that I use for Oracle VDI, available. I set up a few iscsi targets on this solaris server and exported them to my 2 Oracle VM servers. Here's how I did this : (1) On the solaris side : # zpool list NAME SIZE USED AVAIL CAP HEALTH ALTROOT rpool 544G 129G 415G 23% ONLINE - I just have a simple zpool, called rpool, on this box. It has plenty of space available for my needs. So I will use rpool and I will create 5 50gb vols : zfs create -V 50G rpool/ovm1 zfs create -V 50G rpool/ovm2 zfs create -V 50G rpool/ovm3 zfs create -V 50G rpool/ovm4 zfs create -V 50G rpool/ovm5 I want to use these volumes for iscsi so I have to enable them as shared iscsi devices : zfs set shareiscsi=on rpool/ovm1 zfs set shareiscsi=on rpool/ovm2 zfs set shareiscsi=on rpool/ovm3 zfs set shareiscsi=on rpool/ovm4 zfs set shareiscsi=on rpool/ovm5 The command iscsitadm list target should list these devices so make sure they show up. # iscsitadm list target Target: rpool/ovm1 iSCSI Name: iqn.1986-03.com.sun:02:896c766c-0943-4da5-d47e-9575b5a0be36 Connections: 2 Target: rpool/ovm2 iSCSI Name: iqn.1986-03.com.sun:02:a3116b46-73e0-e8c2-e80c-9a4f71aff069 Connections: 2 Target: rpool/ovm3 iSCSI Name: iqn.1986-03.com.sun:02:a838c400-2730-c0d6-f2c2-ee186a0261c1 Connections: 2 Target: rpool/ovm4 iSCSI Name: iqn.1986-03.com.sun:02:2e046afb-d66d-4f3f-c5de-8115e0ddd931 Connections: 2 Target: rpool/ovm5 iSCSI Name: iqn.1986-03.com.sun:02:66109fbe-81ac-ef05-f85e-ab8c1f34cb43 Connections: 2 At this point I want to make sure that I have some access control on these devices. To make it easier, I will create an alias for my 2 servers and use the alias for the ACL. get the iqn from the 2 servers on my 2 ovm servers (wcoekaer-srv1, wcoekaer-srv2) get the content of /etc/iscsi/initiatorname.iscsi (for each server) InitiatorName=iqn.1986-03.com.sun:01:2a7526f0ffff On the solaris side create the aliases : iscsitadm create initiator -n iqn.1986-03.com.sun:01:2a7526f0ffff wcoekaer-srv1 iscsitadm create initiator -n iqn.1986-03.com.sun:01:e31b08110f1 wcoekaer-srv5 Add the ACL to the targets : iscsitadm modify target -l wcoekaer-srv1 rpool/ovm1 iscsitadm modify target -l wcoekaer-srv1 rpool/ovm2 iscsitadm modify target -l wcoekaer-srv1 rpool/ovm3 iscsitadm modify target -l wcoekaer-srv1 rpool/ovm4 iscsitadm modify target -l wcoekaer-srv1 rpool/ovm5 iscsitadm modify target -l wcoekaer-srv5 rpool/ovm1 iscsitadm modify target -l wcoekaer-srv5 rpool/ovm2 iscsitadm modify target -l wcoekaer-srv5 rpool/ovm3 iscsitadm modify target -l wcoekaer-srv5 rpool/ovm4 iscsitadm modify target -l wcoekaer-srv5 rpool/ovm5 (2) the Oracle VM side On each server just do 2 simple things : # iscsiadm -m discovery -t sendtargets -p ca-vdi1 where ca-vdi1 is my solaris server name # service iscsi restart When I do cat /proc/partitions on my servers I will see the devices show up # cat /proc/partitions major minor #blocks name 8 0 160836480 sda 8 1 104391 sda1 8 2 3148740 sda2 8 3 1052257 sda3 253 0 6377804 dm-0 253 1 6377804 dm-1 253 2 6377804 dm-2 8 16 52428800 sdb 8 32 52428800 sdc 8 48 52428800 sdd 8 80 52428800 sdf 8 64 52428800 sde These 5 new devices sd[b..f] are shared storage for Oracle VM and can be used to pass through to the VM's as phy: devices or put ocfs2 on it and use as shared filesystem storage for dom0 repositories. I am setting up an 11gR2 rac template (the cool stuff Saar did) so I am using my devices to create a 2 node RAC cluster with phy: devices.
