• Printer share keeps asking for password and I can't authenticate from any machine. Why?

  - by tenshimsm

  Ubuntu 12.04 printer share keeps asking for password and I can't authenticate from any machine. Why?? We've installed it in two machine (to act as printer servers) and we get the same problem. It doesn't matter what we do, change or install. We can't figure out why the printer share asks for password even using all of the users that are registered in the server. What is wrong with Precise? I want it to work without a password, but it is not even working WITH one! I gave up! The samba version that comes with Precise is insufferable! I tried various settings that didn't work. I should've used Mint from the beginning. [Edit] My printers config. Remembering that samba is 3.6.3 in ubuntu 12.04 load printers = yes [printers] comment = All Printers browseable = yes path = /var/spool/samba printable = yes guest ok = yes readonly = yes create mask = 0700 [print$] comment = Printer Drivers path = /var/lib/samba/printers browseable = yes readonly = yes guest ok = yes

• How do I get a Belkin F5D8053 wireless adapter working?

  - by disassembler

  I've tried getting my Belkin N Wireless adapter to work on Ubuntu many times with no luck at all. Each time I seem to arrive at a dead end. After some thorough searching of UbuntuForums and WifiDocs I've gathered some information and narrowed the problem down to an issue with the rtl819xU driver. Here's some info that may help: $ sudo lshw -C network *-network DISABLED description: Wireless interface physical id: 1 bus info: usb@1:2 logical name: wlan0 serial: 00:22:75:38:52:ac capabilities: ethernet physical wireless configuration: broadcast=yes driver=rtl819xU multicast=yes wireless=802.11b/g/n $ sudo lsmod Module Size Used by vesafb 13449 1 snd_ice1724 106559 2 snd_ice17xx_ak4xxx 13163 1 snd_ice1724 snd_ac97_codec 105614 1 snd_ice1724 ac97_bus 12642 1 snd_ac97_codec snd_ak4xxx_adda 18436 2 snd_ice1724,snd_ice17xx_ak4xxx snd_ak4114 14326 1 snd_ice1724 snd_pt2258 12986 1 snd_ice1724 snd_i2c 13831 2 snd_ice1724,snd_pt2258 snd_ak4113 14307 1 snd_ice1724 snd_pcm 80244 4 snd_ice1724,snd_ac97_codec,snd_ak4114,snd_ak4113 fglrx 2434640 121 snd_seq_midi 13132 0 snd_rawmidi 25269 2 snd_ice1724,snd_seq_midi binfmt_misc 13213 1 snd_seq_midi_event 14475 1 snd_seq_midi snd_seq 51291 2 snd_seq_midi,snd_seq_midi_event ppdev 12849 0 snd_timer 28659 2 snd_pcm,snd_seq snd_seq_device 14110 3 snd_seq_midi,snd_rawmidi,snd_seq dcdbas 14054 0 r8192u_usb 297246 0 snd 55295 16 snd_ice1724,snd_ac97_codec,snd_ak4xxx_adda,snd_ak4114,snd_pt2258,snd_i2c,snd_ak4113,snd_pcm,snd_rawmidi,snd_seq,snd_timer,snd_seq_device soundcore 12600 1 snd parport_pc 32111 1 snd_page_alloc 14073 1 snd_pcm shpchp 32345 0 lp 13349 0 parport 36746 3 ppdev,parport_pc,lp usbhid 41704 0 hid 77084 1 usbhid e100 40108 0 floppy 60032 0 $ sudo iwconfig wlan0 802.11b/g/n Mode:Managed Access Point: Not-Associated Bit Rate:1 Mb/s Retry min limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality=0/100 Signal level=0 dBm Noise level=0 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 I'd like to know if 1) Is the driver is properly installed and recognized by Ubuntu? 2) What can I do to load the drivers properly and make use of the adapter?

  I have a davicom dm9601 USB ethernet card. When I plug in the device, it is detected and drivers are loaded, but I can't connect to internet using it. It works perfectly on XP, other laptop but not working on Ubuntu 11.10 How can I install the driver for this? I have tried many things But nothing is working.

• How do I fix the HDMI/DVI display output with Intel HD 4000 Graphics in 12.04?

  - by YumYumYum

  I have an Alienware Dell PC with Intel HD 4000 Graphics (Ivy Bridge) as verified by the output of lspci | grep VGA posted below. 00:02.0 VGA compatible controller: Intel Corporation Ivy Bridge Graphics Controller (rev 09) The PC only has HDMI and DVI display outputs and using the HDMI output I am only being offered abnormal resolutions. As you can see below it does not even list HDMI1 or DVI1 but just only a fallback. $ export DISPLAY=:0.0 && xrandr xrandr: Failed to get size of gamma for output default Screen 0: minimum 640 x 480, current 1360 x 768, maximum 1360 x 768 default connected 1360x768+0+0 0mm x 0mm 1360x768 0.0* 1024x768 0.0 800x600 0.0 640x480 0.0 How can I fix this? Does it just need to be configured differently or will I need to use a newer kernel (as Intel Graphics drivers are included in the kernel)?

• external display in Ubuntu 13.04

  - by thuc2009

  I have had a look on series of similar topics but I could not find a right answer. Currently, I bought laptop Dell latitude E6530 and installed Ubuntu 13.04 (64 bit) alongside with Windows 7 (I could not get rid of it because of some special programs for work). Ubuntu worked well, however, it did not detect the external displays (Dell 23" and Dell 19") no matter I plugged them before or after booting. Edited: I connected my laptop to those external displays through a laptop dock. I went to Settings- Display, the displays were there, but when I enabled them, Ubuntu logged off automatically. No external display was detected. In addition, the laptop screen sometimes was detected as Dell 23" I got an advice from similar topic that nvidia driver should be updated to version 313 or 319. I upgraded driver and the unity launcher disappeared, main display resolution turned to 640*480 and none of external displays was detected. I tried to use additional drivers, but when I turned it on, it told me that there was no driver to be used. Could some one tell me what should I do ? Edited : options vmwgfx enable_fbdev=1

• Ubuntu sound volume is 40% lower than in Windows

  - by ncomx

  I have 2x 2.1 speakers connected to the computer where I have Ubuntu 12.04 installed. On the software side I've set all the volume controls to 100% with the alsamixer program. The speakers have their own volume control, maintaining those at the same level, and switching between Ubuntu and Windows (XP and 7), on windows the output volume is at least 40% higher, even when having the windows volume control at 50% (without touching the speakers volume control) it's still much higher than the sound on Ubuntu. Why can this be happening? Are there some alternative sound drivers (other than the default ones) I could test to see if it makes a difference? some info about the card: root:$ cat /proc/asound/cards 0 [PCH ]: HDA-Intel - HDA Intel PCH HDA Intel PCH at 0xfbff4000 irq 55 1 [Generic ]: HDA-Intel - HD-Audio Generic HD-Audio Generic at 0xfbcfc000 irq 56 root:$ lspci | grep -i audio 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 04) 02:00.1 Audio device: Advanced Micro Devices [AMD] nee ATI Cayman/Antilles HDMI Audio [Radeon HD 6900 Series] I think the one i am using is the Intel one, the other seems to be from the vga card which is an ati radeon 6950. Running gstreamer-properties and switching between alsa, oss, ossv4 and pulseaudio doesn't seem to make any difference.

• Ubuntu 12.04 - default Radeon driver does not work at all

  - by mumble

  I've recently upgraded to 12.04 LTS and I have an ATI Radeon HD5670. I've heard that the open source 'Radeon' driver is used by default. However, it wasn't showing anything for me. What I did was I added the 'nomodeset' option to boot up and install fglrx. But it didn't work well for me as it introduced a lot of problems (freezes/glitches). So I removed/purged fglrx and am planning to use the open source drivers instead. So my question is this: Why is my default Radeon driver not working? Is anyone having a similar issue? I've also tried using the ubuntu-x-swat driver by running the ff commands: sudo add-apt-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update But the result was the same as the Radeon driver. Nothing shows up on system boot. Any ideas? Thanks in advance! Update Running lspci -nn | grep VGA gives me the following: 02:00.0 VGA compatible controller [0300]: Advanced Micro Devices [AMD] nee ATI Redwood [Radeon HD 5670] [1002:68d8]

• Dual monitors with one above the other?

  - by Felix

  I'm using Gnome 3 and proprietary Nvidia drivers. I have tried to set in nvidia-settings my external monitor to be "above" my main one (it's a laptop). However, when I try to drag a window up from the main display to the external one, it gets stuck and can't move past a certain point. Trying to maximize it changes its decoration so it looks maximized (i.e. no borders, etc), but its size or position doesn't change. Now, if I set my external monitor to be "to the left" of the main one, it works, which is why I'm suspecting this is a Gnome issue, not an Nvidia one. Anyone know how to fix this? Update: some versions: Gnome: 3.2.2.1 Nvidia: 280.13 Update 2: I can see that Gnome 3.4 is out, and among the release notes is better external monitor support. However, they only mention a small fix that is unrelated to my problem. Can anyone with Gnome 3.4 and access to an external monitor please test this out and tell me if it works? I don't want to go through the hassle of upgrading my Ubuntu installation unless I know for certain it's going to fix the problem.

• Internet Timeouts with TP-Link TL-WN821N v2 wireless usb stick

  - by user1622959

  A short time after accessing the internet, the browser/download times out. Before the timeout, the internet works OK briefly; afterwards, the wireless is still connected with a strong signal, but every internet access results in a timeout. When I leave the PC for a while, the internet is back just to timeout again as soon as I start using it. The same happens when I reconnect to the router. Also, when I surf the internet, it takes a couple of minutes until the timeout, but when I download something, it times out in a matter of seconds. The wireless adapter works just fine in Windows and internet via ethernet cable works just fine in Ubuntu. Does anyone have the same problem or knows a solution. I use Ubuntu 12.10 x64. The problem occurs since I installed ubuntu (which was a few days ago). Here some stuff that might be usefull: serus@serus-Ubuntu-PC:~$ lsusb Bus 002 Device 002: ID 0cf3:1002 Atheros Communications, Inc.

• Extension GLX missing...on a desktop PC

  - by Bart van Heukelom

  I just installed Ubuntu 12.10 on a new PC with an Nvidia GTX 560 graphics card, but after installing the Nvidia proprietary drivers (either -current or -current-updates), Unity won't start. When trying to start it manually I get the message "extension GLX missing". I've searched around and found results like this question which point out it's a problem with Nvidia Optimus laptops. However, I don't have this problem on a laptop, but on a desktop PC. lshw output for the graphics card: *-display description: VGA compatible controller product: GF114 [GeForce GTX 560 SE] vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller bus_master cap_list rom configuration: driver=nouveau latency=0 resources: irq:16 memory:f4000000-f5ffffff memory:e0000000-e7ffffff memory:e8000000-ebffffff ioport:e000(size=128) memory:f6000000-f607ffff and CPU: *-cpu description: CPU product: Intel(R) Core(TM) i5-3570K CPU @ 3.40GHz vendor: Intel Corp. physical id: 40 bus info: cpu@0 version: Intel(R) Core(TM) i5-3570K CPU @ 3.40GHz slot: SOCKET 0 size: 1600MHz capacity: 3800MHz width: 64 bits clock: 100MHz capabilities: x86-64 fpu fpu_exception wp vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx rdtscp constant_tsc arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc aperfmperf pni pclmulqdq dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm pcid sse4_1 sse4_2 popcnt tsc_deadline_timer aes xsave avx f16c rdrand lahf_lm ida arat epb xsaveopt pln pts dtherm tpr_shadow vnmi flexpriority ept vpid fsgsbase smep erms cpufreq configuration: cores=4 enabledcores=4 threads=4

• How to help FGLRX detect a device

  - by user113416

  I have HD 4850 card, Ubuntu 12.10 and installed legacy drivers using makson96 ppa. The issue is, that FGLRX can not detect my device and loads vesa bios. I had the same problem on ubuntu 11.10, 12.04 versions. I want to manually help fglrx find a matching device to load as it shoudld do. It is interesting, why does fglrx search for a device in a PCI:0@1:0:1 Bus? in xorg.cof different bus is indicated: Section "Device" Identifier "aticonfig-Device[0]-0" Driver "fglrx" BusID "PCI:1:0:0" EndSection fglrxinfo display: :0.0 screen: 0 OpenGL vendor string: Advanced Micro Devices, Inc.

• Windows Physical Direct Memory Mapping

  - by chrisjleaf

  I'm a bit disappointed there is almost no discussion of this no matter where I look so I guess I'll have to ask. I'm writing a cross platform memory bench marking application which requires direct physical address mapping rather than virtual addressing. EDIT The solution would look something like the Linux/Unix system calls: int fd = open("/dev/mem", O_RDONLY); mmap(NULL, len, PROT_READ, MAP_SHARED, fd, PHYSICAL_ADDRESS_OFFSET); which will require the kernel to either give you a virtual page mapping to the desired physical address or return that it failed. This does require supervisor privileges but that is ok. I have seen a lot of information about shared memory and memory mapped files but all of these reside on disc and are thus not really useful when I'm trying to make a system dependent read. It is very similar to writing an IO driver although I do no need write permissions to the physical address. This site gives an example of how to do it on a driver level using the Windows Driver Kit: NT Insider: Sharing Memory between drivers and applications This solution would probably require Visual Studio which currently I do not have access to. (I have downloaded the WDK api but it complained about my use of GCC for Windows). I'm traditionally a Linux programmer so I'm hoping there might be something really simple I'm missing. Thanks in advance if you know something I don't!

• What is the disadvantage of using abstract class as a database connectivity in zend framework 2 instead of service locator

  - by arslaan ejaz

  If I use database by creating adapter with drivers, initialize it in some abstract class and extend that abstract class to required model. Then use simple query statement. Like this: namespace My-Model\Model\DB; abstract class MysqliDB { protected $adapter; public function __construct(){ $this->adapter = new \Zend\Db\Adapter\Adapter(array( 'driver' => 'Mysqli', 'database' => 'my-database', 'username' => 'root', 'password' => '' )); } } And use abstract class of database like this in my models: class States extends DB\MysqliDB{ public function __construct(){ parent::__construct(); } protected $states = array(); public function select_all_states(){ $data = $this->adapter->query('select * from states'); foreach ($data->execute() as $row){ $this->states[] = $row; } return $this->states; } } I am new to zend framework, before i have experience of working in YII and Codeigniter. I like the object oriented in zend so i want to use it like this. And don't want to use it through service locater something like this: public function getServiceConfig(){ return array( 'factories' => array( 'addserver-mysqli' => new Model\MyAdapterFactory('addserver-mysqli'), 'loginDB' => function ($sm){ $adapter = $sm->get('addserver-mysqli'); return new LoginDB($adapter); } ) ); } In module. Am i Ok with this approach?

I want Ubuntu because of the Software center so I can install things I want until I am familiar with the command line.. I've worked on Computers since I was 12 I remember some of the DOS commands but I guess these are a little different... anyway any ideas? Ive also tried both drivers for the NVIDA card and that didn't help either... its not the card since it did this with both the NVIDA card and the SIS onboard... it also does this on live mode with the USB so I don't think its the HardDrive... I'm running out of options of hardware to try... I know this version of Linux works cuz Ive booted it on other machines and it ran great... what is with this Compaq? here is a vid of exactly what its doing... let me know if you need anything else I am right by the comptuer tonight so ask anything... http://youtu.be/-P-XNo81098

• How can I get my monitor's maximum resolution without the proprietary AMD graphic driver installed?

  - by Venki

  I am using Ubuntu 14.04. I have an AMD Radeon 5570 HD graphic card. Actually, the default open source REDWOOD drivers aren't allowing me to choose my monitor's maximum screen resolution(which is 1366 x 768). I just have two resolutions displayed which are 1024x768 and 800x600 . If I give the command : xrandr -s 1366x768 then the output is: Size 1366x768 not found in available modes So just for the sake of getting 1366x768 resolution I am forced to install the proprietary graphic driver that AMD gives me from its site. But if I install it(which itself is quite a problem-prone process), I undergo a lot of 'inconvenience'. Sometimes after an OS update, the driver crashes unity. Then I will have to uninstall that driver from a tty and google around for a solution. Also I encounter screen tearing problems occasionally. In addition I also cant see my login screen(See this question which states this particular problem). The main problem is AMD does not update its driver as quick as Ubuntu updates its OS. This is quite irritating. So, I want the maximum resolution(and performance) that my graphics card and monitor can give me without installing the 'problematic' proprietary graphic card driver that AMD gives. Is this possible? Suggestions please. Thanks in advance.

• Broadcom BCM4313 takes ages to connect

  - by Drazgo

  I'm having issues with my broadcom BCM4313 wireless adapter. Everything works just fine when connected (with additional drivers & Connman), but it takes about 5 minutes to connect to my network when i just started my computer! When resuming from hibernation it goes very quick though, so just when I boot my pc it's taking forever... This is what I found in the dmesg output: [ 16.778057] eth1: Broadcom BCM4727 802.11 Hybrid Wireless Controller 5.60.48.36 [ 16.808768] type=1400 audit(1295859939.727:2): apparmor="STATUS" operation="profile_load" name="/sbin/dhclient3" pid=833 comm="apparmor_parser" [ 16.808815] type=1400 audit(1295859939.727:3): apparmor="STATUS" operation="profile_replace" name="/sbin/dhclient3" pid=799 comm="apparmor_parser" [ 16.808825] type=1400 audit(1295859939.727:4): apparmor="STATUS" operation="profile_replace" name="/sbin/dhclient3" pid=826 comm="apparmor_parser" [ 16.809367] type=1400 audit(1295859939.727:5): apparmor="STATUS" operation="profile_load" name="/usr/lib/NetworkManager/nm-dhcp-client.action" pid=833 comm="apparmor_parser" [ 16.809415] type=1400 audit(1295859939.727:6): apparmor="STATUS" operation="profile_replace" name="/usr/lib/NetworkManager/nm-dhcp-client.action" pid=799 comm="apparmor_parser" [ 16.809435] type=1400 audit(1295859939.727:7): apparmor="STATUS" operation="profile_replace" name="/usr/lib/NetworkManager/nm-dhcp-client.action" pid=826 comm="apparmor_parser" [ 16.809705] type=1400 audit(1295859939.727:8): apparmor="STATUS" operation="profile_load" name="/usr/lib/connman/scripts/dhclient-script" pid=833 comm="apparmor_parser" [ 16.809755] type=1400 audit(1295859939.727:9): apparmor="STATUS" operation="profile_replace" name="/usr/lib/connman/scripts/dhclient-script" pid=799 comm="apparmor_parser" [ 16.809769] type=1400 audit(1295859939.727:10): apparmor="STATUS" operation="profile_replace" name="/usr/lib/connman/scripts/dhclient-script" pid=826 comm="apparmor_parser" [ 16.844083] alloc irq_desc for 22 on node -1 [ 16.844087] alloc kstat_irqs on node -1 Any ideas how come?

• I can't enable extra effects in Ubuntu 10.10. Please help?

  - by jasoncruz98

  I installed Ubuntu 10.10 alongside Ubuntu 11.10 to use an older version of Compiz. On Ubuntu 11.10, Compiz was enabled by default and I didn't need to use any graphics driver to enjoy the effects. All I had to do was install CompizConfig Settings Manager and enable those extra effects. That was Compiz 0.9.6. Now, after installing Ubuntu 10.10, when I first logged in, the graphics were slow. When I dragged a window from one end of the screen to the other, the whole screen would blur up and pixelate and it would be very laggy. I tried going to System Preference Appearance and selecting Extra effects on the Visual effects tab, but all I got was "Desktop effects could not be enabled". I don't know whether I should install the Additional drivers (proprietary) because my Internet is slow and it would take a long time. Furthermore, in Ubuntu 11.10, after I installed the proprietary graphics driver, I immediately went into fallback mode and wasn't even offered an option to set my desktop session to Ubuntu 3D. I didn't need the driver to run Compiz in Ubuntu 11.10, it just ran so smoothly. But in Ubuntu 10.10, everything is so laggy. Should I install the ATI/AMD Proprietary FGLRX Graphics Driver for Ubuntu 10.10 to enable extra effects? Or is there something else wrong with my system?

• Are Windows partitions gone?

  - by Gigili

  I had Windows 7 on my laptop (factory setting), because of some performance issues, I decided to use recovery options to restore it to its factory condition but I don't know what has happened or what I have done that the whole operating system was gone after playing around with recovery options from the boot menu. I couldn't find Windows, so I installed Ubuntu 11.04 on my laptop. Last time I had Ubuntu on it, it was not really compatible with laptop's configuration and I had a bit of problems trying to do normal tasks I used to do on Windows. Now I want to make sure that Windows and its drivers are gone so that I can try to install a newer version of Ubuntu or Windows. I tried the command sudo fdisk -l And the result shown was: myaccount@myaccount-VPCS116FG:~$ sudo fdisk -l [sudo] password for myaccount: Disk /dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00025b5f Device Boot Start End Blocks Id System /dev/sda1 * 1 38409 308515840 83 Linux /dev/sda2 38409 38914 4052993 5 Extended /dev/sda5 38409 38914 4052992 82 Linux swap / Solaris Disk /dev/dm-0: 4150 MB, 4150263808 bytes 255 heads, 63 sectors/track, 504 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xa668cfe8 Disk /dev/dm-0 doesn't contain a valid partition table Is it gone?

• How to disable a touchpad on an Acer Travelmate 6492?

  - by un pobrecito hablador

  I think it's broken because it starts working in the same way when i install their drivers in windows. It's an acer travelmate 6492. I want to disable it because i think that is broken, however i'm going to write what happens and if someone knows what could be wrong if it's not physically broken, can tell me how to solve it. Well, the main problem is that is scrolling all down every time so i can't do almost anything. I've tried to remove xserver-xorg-input-synaptics but it got worse and it was every time pressing enter or something like that so it was very annoying. Then when i could repair it, i tried with gpointing-device-settings and gsynaptics, but it continued doing the same even with i disabled it from there. The only thing that seems to have a positive effect is to use x(whatever) option instead of gnome when login in and disabling it with xinput. However, it only lasted some minutes before it started working and i had to disable it again. Any idea about how can i disable or fix it? Thanks in advance.

• Only one user can connect to Ubuntu samba server

  I setup a samba server on 12.04 LTS, and it works great for one user but not the others. I am trying to map a network drive from a windows 7 laptop.

• Problems when rendering code on Nvidia GPU

  - by 2am

  I am following OpenGL GLSL cookbook 4.0, I have rendered a tesselated quad, as you see in the screenshot below, and i am moving Y coordinate of every vertex using a time based sin function as given in the code in the book. This program, as you see on the text in the image, runs perfectly on built in Intel HD graphics of my processor, but i have Nvidia GT 555m graphics in my laptop, (which by the way has switchable graphics) when I run the program on the graphic card, the OpenGL shader compilation fails. It fails on following instruction.. pos.y = sin.waveAmp * sin(u); giving error Error C1105 : Cannot call a non-function I know this error is coming on the sin(u) function which you see in the instruction. I am not able to understand why? When i removed sin(u) from the code, the program ran fine on Nvidia card. Its running with sin(u) fine on Intel HD 3000 graphics. Also, if you notice the program is almost unusable with intel HD 3000 graphics, I am getting only 9FPS, which is not enough. Its too much load for intel HD 3000. So, sin(X) function is not defined in the OpenGL specification given by Nvidia drivers or something else??

• Error: kernel headers not found. (But they are in place)

  - by Guandalino

  I'm trying to install the Guest Additions in VirtualBox 4.04. Host OS is Ubuntu desktop 11.04 64bit, guest OS is Ubuntu server 11.10 64bit. $ sudo ./VBoxLinuxAdditions.run After some output this line is printed: The headers for the current running kernel were not found. But the headers are installed, at least accordingly to dpkg: $ dpkg --get-selections | grep linux-headers linux-headers-3.0.0-12 install linux-headers-3.0.0-12-server install linux-headers-server install The running kernel is: $ uname -a Linux foobar 3.0.0-12-server #20-Ubuntu SMP Fri Oct 7 16:36:30 UTC 2011 x86_64 x86_64 X86_64 GNU/Linux How do I fix things so that Guest Additions installer is able to find kernel headers? Update: added full output. The headers for the current running kernel were not found. If the module compilation fails then this could be the reason. Building the main Guest Additions module ...done. Building the shared folder support module ...fail! (Look at /var/log/vboxadd-install.log to find out what went wrong) Installing the Window System drivers ...fails! (Could not find the X.Org or XFree86 Window System). I don't care for fail #2, because that's a server and I don't need X server. But I need shared folder support. Some further detail: $ tail /val/log/vboxadd-install.log .......... cc1: some warnings being treated as errors make[2]: *** [/tmp/vbox.0/vfsmod.o] Error 1 make[1]: *** [_module_/tmp/vbox.0] Error 2 make: *** [vboxsf] Error 2

• How to ensure nvidia_current module loads during boot

  - by Aras

  I am running Ubuntu 12.10 on an Asus G75V laptop with nvidia gforce GTX 660M. I first run 12.04 on this machine and was able to install nvidia_current drivers from swat ppa: sudo apt-add-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get install nvidia-current This worked in 12.04 and after rebooting the machine my graphics where working properly. After upgrade to 12.10 however, the machine boots into a low resolution desktop which I can not really interact with. I suspect this is due to the driver not being loaded properly. To fix this, I have to switch to ctrl+alt+F1 session and manually load the nvidia_current module and restart the desktop manager: sudo modprobe nvidia_current sudo service lightdm restart Now everything works fine again. However, I would like not to have to do this every time I reboot the machine. I also dont want to hack an script to do this on load. Basically, if things are setup currectly, the nvidia_current driver which is installed should load. How can I make sure nvidia_current driver module loads properly when system starts?
