• PCI hotplug doesn't seem to work

  - by user245454

  In virsh I detach a PCI bus from host and attach it to a VM. I don't see any errors in these steps. But I don't see the PCI device listed in the VM. virsh # nodedev-dettach pci_0000_01_00_0 Device pci_0000_01_00_0 dettached virsh # attach-device VM1 pci_add.xml Device attached successfully $ cat pci_add.xml <hostdev mode='subsystem' type='pci' managed='yes'> <source> <address domain='0x000' bus='0x01' slot='0x00' function='0x0'/> </source> </hostdev> Is PCI hot plug not supported? I am using Ubuntu 12.04.3(kernel 3.8.0-34). I can add the same PCI device through virsh edit VM1 and start the VM1. This way I am able to see the device.

• Velvet screen after grub selection

  - by Spleen

  After a fresh install of Ubuntu 11.10 64-bit, the boot seems to stop after selecting the ubuntu option (same with the rescue one) in the grub menu. At first I thought this was related to grub-efi, as I've had similar problems after a Ubuntu 11.04 update which replaced grub-efi with grub-pc and got me stuck on a "elf magic" grub console (https://bugs.launchpad.net/ubuntu/+source/apt/+bug/800910). While the 11.04 problem was resolved with a simple chroot and apt-get install from the live cd, that solution doesn't work this time. The drive with the bootloader is a sata3 ssd with 64 gb gpt (sdb1 20 mb efi boot partition fat16, sdb2 60 gb root ext4 and sdb3 4 gb swap) on a msi e350ia-e45 mainboard with a pair of 2 TB ext4 mbr drives for photos/music/movies. I've tried a few grub-install/update-grub with boot-directory sdb1 from chroot, but I cant seem to go anywhere. Even this guide: http://en.gentoo-wiki.com/wiki/Grub2#EFI (ofc I replaced grub2 with grub in the grub-install and efibootmgr commands) doesnt seem to get me anywhere. Any help or ideas are appeciated ;) edit: I guess its the combination of gpt/uefi that also seems to haunt f16 edit: same with 12.04 beta btw

• Custom wallpapers under "Appearance" are dissapearing [12.04]

  - by user73449

  When I add wallpapers via the little "+" under "Appearance Look" in the settings, I can select them and it works fine. But when I reopen the Appearance setting and want to change my wallpaper, the custom ones are gone. Why is this? Below is a screenshot of the empty custom wallpaper section. Unfortunately I don't know what this is called in English, so I have a hard time searching for my problem. http://i.stack.imgur.com/eyytG.png

• I can't autostart xfce4 power manger lubuntu 13.10

  - by user203766

  I just upgraded my 64 bit lubuntu to 13.10 on my netbook today. After the upgrade, I simply can't autostart the xfce4 power manager. I tried to add from the desktop session settings, I tried to copy the power manager.desktop file to ~/.config/autostart folder. Everything looks fine, than I logout, log back in, and the darn power manager, just won't start automatically. It only starts when I double click the icon, or if i start it from the terminal. Help me please

• Grub-Customizer made Windows 7 disappear from Gurb2

  - by user199055

  I am running dual-boot Ubuntu 12.04/Windows7. I wanted to change the boot order in Grub2 to have Windows on top of the list. I installed Grub-Customizer on Ubuntu 12.04 using the following terminal commands copied from another post: sudo add-apt-repository ppa:adabbas/1stppa sudo apt-get update sudo apt-get install grub-customizer After installing, I launched Grub-Customizer from Dash Home. Windows 7 does not appear in the list. I closed the program and was prompted to save the current settings. Upon rebooting, Windows did not appear in the Grub2 list. I went back into Grub-Customizer and clicked the "Revert" button but still no Windows 7. Does anyone know how I can fix this?

• Upstart Script: Detect Shift Key Down At Boot

  - by bambuntu

  I want to create a boot up potential which allows a different upstart/runlevel configurations to load based upon specific key downs at boot (or combos). How do I detect a key down event with an upstart script? I'm offering a bounty. The deal is you must provide a very simple piece of working code to do this. I will immediately check the code and verify that it works. I'm on 10.04 if that helps. Alternative methods to achieve the same result are acceptable, i.e., if grub could somehow show entries that would indicate a type of boot, where that boot would cp appropriate files to /etc/init. So, instead of a keydown solution, it would be a boot menu item solution and the way to get grub to copy upstart scripts to /etc/init. If possible.

• Library search paths

  - by David Clements

  This question originally started in an apparent problem in Cups calling various back-ends and using non-standard library search paths. If I want to change a library search path for a app running in a terminal I can use LD_LIBRARY_PATH, RPATH, etc., but if I want to change a library path for a Cups back end, I subsequently resolved the Cups issue, but I don't see any mechanism to change the search path whare an app is not running in terminal. For example Cups calls backendA and backendB to print on 2 printers, BackendA uses libxxx.1.15 and BackendB needs libxxx.1.05, is there any way to change the library search path for backendB (only) without recompiling backendB, (I may not have the source)? Any ideas?

• Unity elements sometimes appear while full screen in Virtualbox - how to stop it?

  - by frumbert

  Launcher is great, and it helps me finds stuff. I have the latest release of 12. But when I'm full screen in VirtualBox running another operating system and I hit some key combination I haven't yet figured out, Unity suddenly grabs keyboard focus. It might be alt-tab, it might be left-control x. I have physically pulled both the windows key and FN key off my laptop because they get in the way, so it's probably not the windows key. You don't know the focus has been stolen because the full screen app (VirtualBox) is still full screen and the Unity element is in the background. But you're busy typing into a Unity box, not your foreground application. This is particularly annoying. In my screenshot (taken from a camera, because the built in screen capture program can't capture a screenshot containing the launcher...) the windows VM is the foreground application, but the "Run Command" entry box has come up and is capturing the keyboard: I would like a foreground full screen app to stay that way. Is there a way that I can keep Unity but only have it activate its elements (e.g. pop out with its search box) if I physically click a button, not type some random key combination that foreground applications can get confused about? Otherwise I can do without the launcher or other elements, because doing my actual work is more involved than just launching programs.

• Mouse wheel on Dell Vostro V13

  - by Scaine

  I have a Dell Vostro V13, which Canonical claim is "Certified" for Ubuntu (http://www.ubuntu.com/certification/make/Dell/laptops). So it surprises me that the synaptics trackpad isn't recognised as such and defaults to psmouse emulation. This means no multitouch, no gestures, and more importantly, no mousewheel scrolling. Because it's not loading the synaptic driver, running gpointing-device-settings doesn't help. I've found this bug : https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/380126 which suggests a fix has been committed, but I can't see a way of getting this loaded on my Maverick build. I've tried backports and proposed repos in synaptic, but no joy. Any ideas?

  - by dellphi

  I use a dual boot with two hard disks and two OS is Ubuntu 10.04 and Windows 7. Windows 7 installed on the first disk, first partition. Grub is installed on a second hard disk MBR, and Ubuntu installed on an extended partition on a second hard drive. When I select Windows 7 on the Grub menu, the HDD lamp lights up briefly and then black screen on the monitor, with the status of the keyboard is still functioning. Until now (with the default boot from first HDD), I have to press F12 to get into the Grub to run Linux on a second HDD. output of fdisk -l grub.cfg. I want to retain Grub to remain on the second HDD, and Windows 7 could choose from the menu provided by Grub. But I do not get how, I hope anyone can help.

• ubuntu 11.10 on MacBookPro 7,1 can only see one cpu

  - by gozzilli

  On a MacBookPro 7,1 running ubuntu 11.10, System monitor only sees 1 core (instead of 2). cat /proc/cpuinfo | grep 'cpu cores' also gives: cpu cores : 1 I followed this guide and added acpi_apic_instance=2 to the line with GRUB_CMDLINE_LINUX_DEFAULT, but that doesn't seem to change the situation. What can I do? I'm using rEFIt, installed under MacOS, and running in dual boot with MacOS. After the rEFIT menu, I'm still presented with the GRUB menu (I'm assuming that's normal). I saw similar posts on this matter, but could not fix my problem with what they suggested. Any help appreciated. Thanks!

• How do I change the cursor and its size?

  - by Thomas Le Feuvre

  I have recently created an Ubuntu 12.04 partition on my Windows 7 laptop. When installing it, I switched to "high contrast" mode, which has rather large cursors (by large I mean about twice as large and thick as they should normally are). Now I have successfully installed the partition, the large cursors have stuck around even after exiting this high contrast mode, but only when I am hovering over stuff e.g. hovering over text inputs, links, and when resizing windows. All of these cursors are too large. They cursor is only normally sized when the computer should be displaying the normal mouse pointer. Does anyone know how I might go about fixing this?

• For some reason I can't get ATI FGLRX Drivers to support 3D acceleration on Ubuntu 12.04

  - by HungryMan

  I have an ATI 5650m and I've had 0 issues with 3D Acceleration in the past. I had to reinstall Ubuntu entirely, and now with the 12.6 drivers I get - One or more tools required for installation cannot be found on the system I can't seem to solve this issue. I installed the FGLRX drivers through the "alternate command line" guide on the Ubuntu Wiki including the instructions for getting 3D support. They seem to install but I get an error with vainfo libva: VA-API version 0.32.0 Xlib: extension "XFree86-DRI" missing on display ":0.0". libva: va_getDriverName() returns 0 libva: Trying to open /usr/lib/x86_64-linux-gnu/dri/fglrx_drv_video.so libva error: /usr/lib/x86_64-linux-gnu/dri/fglrx_drv_video.so init failed libva: va_openDriver() returns -1 vaInitialize failed with error code -1 (unknown libva error),exit I have tried help here: http://ubuntuforums.org/showthread.php?t=2014440 It's a bit frustrating as I can do basically nothing without 3D support. I can't use super + direction or super + w or even configure the Unity bar to be 32px. If anyone could help I'd appreciate that.

• My laptop shuts down when I remove the charger

  - by Hakim0

  Laptop shuts down when charger is removed. As well I get a message when booting up saying disk drive for /media/3936-3939 is not ready or not present. About a week ago I was trying to install a matlab iso file using mount commands etc... I tried mount, fuseiso, and UNETbootin. I have a feeling this may have something to do with message I'm getting from booting up. If anyone can point me in the right direction or help me out. Many thanks.

• Android device connects to my computer, but doesn't play audio over Bluetooth

  - by bi99l35

  I turn on Bluetooth on both my devices and open up Music on my Android. I select a song to play, press the menu button, and tap "Via Bluetooth": I tap on my computer in the "Bluetooth Device Picker": Then it says, under the name of my computer: Connected to media audio Now I should technically be able to play music through my computer, since it "Just Worked" in Kubuntu with Blueman. But nope, something must be up with PulseAudio, because I hear no sound from my computer (I'm running Xubuntu 12.04). The reason I say this is that the devices list in Blueman shows indication of data transfer and it says it's connected, but in the PulseAudio Volume Control has no indication of my Bluetooth device (or Blueman) playing audio.

• Avoid random disk names

  - by BarsMonster

  Hi! I have Ubuntu Server 10.04 1 system disk, and 5 disks in RAID-5 configuration. The problem is that names of these disks are changed from time to time, they are being randomly mixed from time to time (sda,b,c,d,e,f - so system disks might be sda, or sdc at different time for example).... is there any way to fix drive names, so that even if it's disconnected for example, no other drive can occupy this letter based on disk UUID or something?

• Delete U3 System from SanDisk Cruzer USB Drive [closed]

  Possible Duplicate: How do I get rid of “U3 System” on my USB drive? SanDisk Cruzer come with a "U3" malware built into them.

I'm aware of the windows program, but I don't have access to any, and in any event, I wouldn't want to insert the stick into a windows box because it automatically installs its malware to any windows box comes into contact with! A friend of mine realized you could delete the cdrom via sudo echo "1" > /sys/class/block/srXXX/device/delete But it will come back if you reboot.

• Why do I have Unity and GNOME Classic running at the same time?

  - by jerowin

  I've recently updated and found that Unity shows on the gnome-classic/fallback desktop. Is this a new feature (which I doubt to be), or a bug? If it is a bug, tell me how to disable Unity because it interferes with the lower panel (i.e. I bring out Trash instead of showing the desktop when I try pressing the "Show desktop" button when the panel is not in focus). I don't encounter this problem in gnome-classic (No effects). Don't judge me. I like pokemon!

  First of all, I've tried to install adobe air on ubuntu 13.10 64-bit without any success (yes, I've read the posts here, but none of them have helped (it's always some dependency that says "but it wont be installed"). Then I decided to try running it thru wine. Installed adobe air with no problems. Now the tricky part - how do I run it ? Adobe Air has only exes' to update itself, and the minerva has and .air extension. Ive tried even something like rundll32 Adobe Air.dll (with no success of course).

• ubuntu 12.10 Lenovo b570e, WiFi connected but not working

  - by koogee

  I'm running ubuntu 12.10 liveUSB on a lenovo b570e. It has an atheros wifi card that connects with my home network but I can't browse AT ALL. My network is multiple clients --> router --> isp modem --> Internet I can ping my router (192.168.0.1) but not my isp's modem(192.168.15.1). I have 3 other computers connected to the same router that are working fine (infact i'm posting from one) ping -c 3 google.com unknown host google.com ping -c 3 8.8.8.8 shows 100% packet loss I think its some networking issue. I tried directly connecting it to the router via ethernet cable but same issue. It gets an ip, shows LAN connected but can't browse. If I connect it directly to the isp modem via ethernet cable it starts working fine. Connection Information shows: Interface: 802.11 wifi (wlan0) driver: ath9k security: wpa/wpa2 speed: 150mb/s ip: 192.168.0.106 broadcast: 192.168.0.255 subnet:255.255.255.0 default route: 192.168.0.1 primary dns: 192.168.15.1 i have restarted the router and modem many times.

• PC noisy due to high load - why?

  - by Jinx

  I just installed an ubuntu on my pc(Dell Inspiration I560SR-358, with CPU E5700 3GHz, 4G memory, and NVIDIA GeForce G310). The pc becomes noisy before that it's quiet with a windows 7 on it. How come? How to set it to be quiet again in unbuntu 10.04. One of the two cpu usage is always 100%. I think that is the reason. //re-edit Everything gets ok after I restart the computer.But the fan is still running which makes it noisy, if i switch to windows 7, it becomes quiet again.
