• new installation won't sync directories with my account

  - by barrydrake

  I had a dual-boot arrangement on my desktop with 12.04 and 12.10 (testing). Last week, I managed to trash both and ended up re-installing both. After doing all the updates, I activated Ubuntu-one which worked just fine on the previous installations. On both 12.04 and 12.10, the Ubuntu-One window fails to show the folders for syncing and only syncs the Ubuntu-One folder. Adding a folder on my net book on which sync is working properly brings up a pop up on my desktop that tells me a new folder is available for syncing - but the Ubuntu window fails to show it. I have put a screenshot from my net book (working OK) and one from my desktop which shows the problem. Any suggestions please?

• Did You Know Facebook Has Built-In Shortcut Keys?

  - by The Geek

  I was spending some time browsing around Facebook today (translation: wasting time), when I noticed that they have some shortcut keys for navigating around the site using the keyboard, so I put together a list for everybody. Note: for each of these shortcut keys, if you’re using Firefox, you’ll need to use Shift+Alt instead of just Alt, and for Internet Explorer you’ll need to hit the Enter key after the shortcut to trigger it. If you’re using a Mac, you’ll need to use Ctrl+Opt instead of Alt Latest Features How-To Geek ETC How To Boot 10 Different Live CDs From 1 USB Flash Drive The 20 Best How-To Geek Linux Articles of 2010 The 50 Best How-To Geek Windows Articles of 2010 The 20 Best How-To Geek Explainer Topics for 2010 How to Disable Caps Lock Key in Windows 7 or Vista How to Use the Avira Rescue CD to Clean Your Infected PC 2011 International Space Station Calendar Available for Download (Free) Ultimate Elimination – Lego Black Ops [Video] BotSync Enables Secure FTP File Synchronization on Android Devices Enjoy Beautiful City Views with the Cityscape Theme for Windows 7 Luigi Installs Any OS on Google’s Cr-48 Notebook DIY iPad Stylus Offers Pen-Based Interaction on the Cheap

• Brightness fn key adjustment problems

  - by npCoder

  My brightness function key controls work after setting grub boot parameter to "acpi_osi=" but using them I cannot adjust the brightness higher than around 70% (there is empty bar left over and I can't adjust higher) unless I go to Brightness & Lock settings manually than I can use the slider to adjust it higher... I primarily use intel_backlight to adjust my backlight and I am running Linux kernel 3.14.1 on Ubuntu 14.04 LTS on an ASUS X550LA Laptop when I try: cd /sys/class/backlight/intel_backlight cat max_brightness 937 cat brightness 811 It seems that I can only adjust to a maximum of 811 using the fn brightness controls If I instead do cd /sys/class/backlight/acpi_video0 cat max_brightness 10 cat brightness 4 cat actual_brightness 10 With the FN keys actual_brightness is not equal to the value returned from brightness on acip_video0 (which is always 4) but on intel_backlight actual_brightness = brightness The adjustment problem seemingly arises because both intel_backlight and acpi_video0 are trying to adjust brightness

• Failure to start grub with Wubi

  - by Marco Ceppi

  My laptop battery ran down and died while using Ubuntu 10.04 with Wubi. Upon recharge (and restart) selecting Ubuntu from the Windows Boot menu brings me to the typical prompt which says (and I paraphrase): Trying hd(0,0) on Disk... After that the screen flickers to white (for a split second) then black. No grub menu comes up (as I would expect) no cursor, no grub sh prompt. Nothing. I've tried switching TTYs to no avail. As there are no logs, I can't trouble shoot anything. I've run a check disk from windows (on the NTFS partition the root.disk is stored) with no luck. What is causing this failure to load grub (and, by association Ubuntu) - How can I restore my setup and get Ubuntu via Wubi working?

• Setting up a GUI-based libvirt VM

  - by LibertasMens

  I am attempting to create a virtual machine using libvirt that will have a GNOME GUI and remote accessibility. I have successfully set up the VM to run, but I am unable to access it remotely.

• Theme changes after resuming from suspend

  - by mouche

  I'm using a Dell Inspiron 1520 and Ubuntu 10.10. I've read a lot of questions about graphics problems after resuming from suspend, but most of them are much more serious than mine. I can boot, login and use Ubuntu fine. The problem is that my theme for my top bar and bottom bar changes to gray and blocky (not rounded). Oddly enough, the theme for the title bars of my windows stay the same dark theme. Any ideas how I can fix this? It works fine if I logout and log back in.

• How can I fix intermittent iSight camera functionality on a Macbook Pro 5,2?

  - by Mmmm

  I have a Macbook Pro 5,2 laptop dual booting OSX and Ubuntu. The built-in iSight video camera works only sporadically. By that I mean that sometimes if I boot and try to use the camera it does not work (most of the time) but other times it does. I don't have good repeatable data regarding when it does vs. when it doesn't other than to say that it always seems to work right after I upgrade to a new Linux kernel with the Update Manager and reboot, but then eventually stops working again until I upgrade the kernel again. That is hard to test repeatably, so it's hard to know for sure that that is the case. This has happened consistently with every version of Ubuntu from 10.10 through 11.10. I can get around this by booting into the OS/X partition, since all of the hardware obviously works perfectly on that side of things, but it would be great if I could remain in Ubuntu and do the same thing. Thanks in advance for any inSights.

• GeForce8800 ultra

  - by Gunnar

  I have been running Ubuntu 10.04 with GeForce 8800 Ultra graphics card without any problems for many months until a few days ago, after some updates, everything stopped working. Can't use Stellarium (my favorite program) and everything (even the mousecusor) stops responding for a long time. Takes ages to load the desktop and everything is just "f..." B.t.w. I have a dual boot and WinXP is not having this problem with the 8800 card. So, elementary... What's going on between Ubuntu and Nvidia? Best regards Gunnar

• Broadcom bcm4311 rev2 Full disabled on battery

  - by Antonio BG

  Ok this is my problem... My problem begins while ago when I installed ubuntu 10.10. (is the same with 11.04,11.10...) My wireless card is disabled if the power cord is unplugged, and the only way to fix this is rebooting my pc WITH the power cord plugged and if I use lspci command, it doesn't show me the wireless card. is like if I've removed the wireless board from my laptop port. I've searched a lot of solutions for bcmw4311 issues, but none of them fix my problem because when apply one of the fixes, if I unplug the cord, my wireless card it just gone away... I have dual boot on my pc(w7,ubuntu), I've tried with full installation just to see if this is the problem, but not, is the same. On windows all work correctly with and without power cord.. so this is not a hardware problem, is more like a kernel problem. anyway I can use wireless with power cord plugged, but c'mon this is a laptop not a desktop pc XD haha any help is welcome

• Is the Lenovo Ideapad Z570 fully compatible with 12.04?

  - by umpirsky

  I'm looking for some notebook that will run on Ubuntu perfectly. I like LENOVO IdeaPad Z570, but I'm not sure how it will perform on Ubuntu. I heard people are complaining about wireless problems. Here is full configuraion: Processor Intel Core i5 2430M 2.4GHz - 3.0GHz Chipset Intel HM65 Express Memory 4GB DDR3 1333MHz Graphics NVIDIA GeForce GT 520M 1GB HDD 750GB SATA II Wireless 802.11b/g/n, Bluetooth 2.1 Network adapter Ethernet LAN 10/100Mbps Ports VGA, HDMI, 3x USB 2.0, eSATA Does anyone have experience with this model? Any problems noted? I heard there is a test suite, how can I install it? Maybe I can boot live CD and try it myself before buying it. But, unfortunately, sometimes something works on live CD, but not when you install it. I guess critical components here are graphics and wireless. Any feedback would be appreciated.

• Mouse cursor lag after lock screen, 64 bit 12.04

  - by Bill Jones

  Recently I have noticed that when I return to my computer after it has been "locked" for a while, the mouse pointer has significant lag. The cursor position appears to only update a few times a second. Moving the mouse results in the pointer "following" the movement in a jerky kind of way, and then continuing for some fraction of a second after I have stopped using the mouse. Replacing the mouse has no effect. (I have two differently branded and constructed usb optical mice). Plugging either mouse into a different usb port has no effect. Once the problem was resolved by "suspending" the system, and then re-starting it with the power switch, but this does not work every time. So far, the only fool-proof fix is to shut the system down and re-start it (re-boot). I have tried this suggested fix. It had no effect.

• Monitor Display issue

  - by dsiddens

  When booting I will have to boot maybe 3 or 4 times to get a screen that is not displayed diagonally or is not using the full screen width. Hardware specification: HP s7727c with AMD64 and NVIDIA chipsets and Insignia 22" monitor/TV. The Ubuntu version is 9.10 Karmic. I'd like to stay current with Ubuntu on this machine, but have gone down to 9.10 to get this described functioning. I tried higher versions and could not get past the "black screen" I think this issue is connected to the NVIDIA chipset/driver problem. I am a GUI user and I don't follow the other solutions posted which make use of the command line. I suppose if the command line solution could be given without making any assumptions of the receiving person's knowledge base, then even I and others like me, could implement it. Thank you for your time and assistance. Doug

• If I intend to use Hadoop is there a difference in 12.04 LTS 64 Desktop and Server?

  - by Charles Daringer

  Sorry for such a Newbie Question, but I'm looking at installing M3 edition of MapR the requirements are at this link: http://www.mapr.com/doc/display/MapR/Requirements+for+Installation And my question is this, is the Desktop Kernel 64 for 12.04 LTS adequate or the "same" as the Server version of the product? If I'm setting up a lab to attempt to install a home cluster environment should I start with the Server or Dual Boot that distribution? My assumption is that the two are the same. That I can add any additional software to the 64 as needed. Can anyone elaborate on this? Have I missed something obvious?

• How do I know if my firewall is on?

  - by paercebal

  I installed Firestarter, and configured my firewall. But I'm in doubt : On boot, I sometimes see a [FAIL] marker, and to the left, I guess it was something like "start firewall". I can't be sure because the message is seen for less than a second, so I wanted to know if there is a way, without starting the whole firestarter software, to know if the firewall is on and working, or not. Either a gadget, or better, some console instruction, the exact name of the firewall process/daemon, or bash script, will do. Edit: I already tested my computer with the "Shield's Up" http://www.grc.com feature, which marks my computer as "Stealth", but as I am behind a router, I'm not surprised. Still, apparently, my computer answers to pings... Strange...

• Various crashes in 12.04 after upgrade and fresh install

  - by stefan

  Ubuntu drives me crazy. Since I upgraded from 11.10 64-bit to 12.04 Ubuntu crashes regularly. One time the crash report tells me that Skype is the faulty app, another time it was Opera, and today the crash report tells me Xorg crashes. I read that it can be caused by a faulty upgrade so I made a clean new installation of 12.04 32-bit. But the error is the same. I had a look in the log files with a friend but we did not find a answer. This morning the crashes happened like this: Boot Auto-start Thunderbird Start VLC for radio Start Opera Working a while (30 minutes) Starting Skype 2 minutes later, the system freezes, the monitor turns black, a login screen appears and I enter my password. The desktop comes up again and the crash report pops up.

  - by user109162

  Iam a total newbie to Ubuntu . I installed Cinnamon through terminal . The problem is that when i boot up, if i don't enter the password before 1 or 2 minutes the password field will freeze and won't accept any text inputs.The problem was most likely caused by Cinnamon because i guess the problem started after i tried to install some Cinnamon extensions. Please answer in non-technical way as far as possible. I will never go back to Windows whatever be the outcome. Help me stay on to Ubuntu.

• Apt Configuration problem

  - by Paul

  I am trying to load v11.04 onto my HP desktop hard drive using a USB drive. I used the same USB drive to load the system on my Dell netbook and it loaded successfully. But trying to load on the desktop I get the error " Apt configuration problem. An attempt to configure apt to install additional packages from the CD failed" The installer then crashes. I have nothing in the CD drive. I can boot the system from the USB drive and it works fine. I have tried all options on the load with the same crash each time. I baffled as I successfully loaded my netbook with the same USB with no problems.

• After Upgrading to 12.04 the Kernel won't Initiate

  - by Jeff

  I had 11.10 and tried to upgrade recently, via the installer pop-up reminder. Afterwards it would not boot, citing an issue with the kernel. So I've setup a 12.04 installation USB, which appears to work fine. The problem is it doesn't provide an upgrade option, just format and install or install alongside the current broken kernel. I believe I should be able to still get the information from the broken OS after installing alongside, but if there is a way to fix this more directly that would be preferable.

• Ghosting Program for Ubuntu 12.10

  - by Sean Webber

  I am looking to figure out how to set up a mass backup system for a computer network (of about 25) and am looking for a ghosting program that makes an image of the entire system for backup/recovery purposes. While clonezilla would work.. you have to manually boot us the CD for it. I am looking for a program that runs INSIDE Ubuntu that sends a system image backup off to the network server at set times, then when needed could also be used to burn the clone back to the machine. Another words- automatically and the only time I have to do anything to it is when I need to burn a backup BACK to a 'crapped' machine. Any ideas?
