• Display Problems running Ubuntu 12.04 in Windows VMware Player

  - by Alex Reynolds

  I am posting this again because I have changed to VMWare Player and I discovered something new. I am running Ubuntu 12.04 LTS (Guest) in VMWare Player 6.0.2 on Windows 7 64-bit Host. I have VMWare Tools installed properly. I am running MATE but the problem persists when I change (to and from) xfce, gnome, mate a-- and back again I had been using this for a couple of years without any graphics issues. After an Ubuntu update (typical) -- my video is corrupt and will not refresh correctly. My desktop icons are "mirrored" and when I open a terminal window (for instance) -- sometimes -- the window appears multiple times. Of course, only one is the real image. It seems to be a refresh problem. When I move an active window around the screen the "older" images "erase" and my icons (for instance) are in the correct location. For instance, I can move the terminal around a pretty corrupted window and the screen behind it is repainted correctly. NEW: Next, I got the idea to try and Remote Desktop in to the Ubuntu 12.04 LTS Guest OS from my Windows 7 64-bit Host. Once working, and connected via Win RDC -- using MATE as default in my /etc/xrdp/startws.sh -- my video is not corrupted and works fine (as in the past). Any ideas about what is going on ? or how to fix this ?

• How can I make KDE faster in Ubuntu 12.04. It's very slow

  - by Rizwan Rifan

  I installed the kubuntu-desktop package in Ubuntu 12.04 LTS, but the problem is KDE responses very slowly. If I click on an application's icon to run it, it appears after 10 seconds and sometimes does not appear at all. It hangs all the time. The cursor is almost impossible to follow because of the lag. I have read on the Internet that Unity uses more memory and CPU than KDE. But on my PC Unity runs smoothly and KDE does not. So what should I do to make KDE as fast, responsive and smooth as Unity? My specifications are as follows: RAM: 1.5 GB (DDR2) Processor: 3 GHz Dual Core Graphics Card: Intel HD graphics with 256 MB memory.

• How can I optimise ext4 for reliability?

  - by amin

  As ext4 was introduced as more reliable than ext3 with block journals, is there any chance to suppose it 100% reliable? What if enabling block journaling on it, which is disabled by default? As friend's guide to explain my case in more detail: I have an embedded linux device, after installation keyboard and monitor is detached and it works standalone. My duty is to make sure it has reliable file-system so with errors there is no way for manual correct faults on device. I can't force my customer to use a ups with each device to ensure no fault by power-failure. What more can ext4 offer me besides block journaling? Thanks in advance.

• Is there an official Ubuntu free technical support team?

  - by João Pinto

  I have found that there is an "Ubuntu Support Team" at https://launchpad.net/~ubuntu-helpteam but I am not sure it's official or active. Please note that I am not referring to bug fixing support, I am referring to the broader OS support, with people available to engage users needing support with a problem and drive it to a proper resolution. Is there an official team for this purpose with a clear scope and activity plan ?

• Speed up ssh login using public key down to 0.1sec

  - by BarsMonster

  Hi! I am using Putty to login to my local server, but it takes about 1.5 seconds to login (from the click on 'connect' to working command prompt, most of time is spend on "Authenticating with public key..."). I know many see even slower speeds, but I would like to have not more than 0.1 login time. I already set UseDNS=no and allowed only IPv4 in putty client and reduced key length from 4k down to 1k. Any other suggestions to speed it further?

• recover from sudo rm -rf command

  - by user106116

  By mistake, I ended up executing "rm -rf /" command from sudo on my laptop which erased many files before it stopped. Now when I restarted my system , it gives a GRUB rescue prompt. I am having dual boot with Ubuntu 12.04 and Windows 7 I request the help for following: How do I fix the currently installed Ubuntu without overwriting/erasing the left over files (from rm -rf command)? Is using Boot-Repair safe ? Is there a way to directly go to Windows 7?

• Numlock doesn't work after logging in

  - by Tobi

  I've a strange problem after upgrading to Ubuntu 11.10 The Numlock of my Apple Keyboard (white, wired) doesn't work anymore. Strange thing because it works with the guest account but not with my user account. I did change the lightdm.conf to get the numlock working for the login and it works, but nor in my user account. Even stranger, pushing zero effects a right click? I also tried different keyboard layouts, but it shows Numlock on (stuck on) but doesn't work. Any idea which config file stores information about this?

• Second Monitor stays black/in power save mode

  - by Rob

  I'm using two Monitors, a Belinea o.display 1 (Recognized as a Rogen Tech Distribution Inc 20" by Ubuntu, but working fine) on the DVI-Output (connected via DVI-to-VGA-adapter) as my primary Monitor and a Dell 19" (Recognized correctly) on the HDMI-output (via HDMI-to-DVI adapter) as secondary monitor. The graphics controller is a GeForce 9500 GS. I'm running a fully updated Ubuntu 13.04 with nouveau 1:1.0.7-0ubuntu1. The problem is that the second monitor (Dell) never seems to come out of standby during boot: the screen stays black and the status led on the monitor stays orange (it's green when it's on). It is correctly recognized an the size of the desktop is set accordingly, it just stays black. Changing any setting via xrandr/arandr/etc. does nothing. The on-screen-menu of the monitor reports it to be in power save mode. When using the proprietary NVIDIA-Drivers, the second monitor works just find. But these drivers cause a lot of other problems on my system, so i would really like to avoid them. On Ubuntu 12.10 i had found a workaround: When moving the relative position of the second monitor slightly down and the up again, it would turn on and function normally: xrandr --output DVI-I-1 --mode 1680x1050 --pos 1280x0 --rotate normal --output HDMI-1 --mode 1280x1024 --pos 0x88 --rotate normal sleep 2 xrandr --output DVI-I-1 --mode 1680x1050 --pos 1280x0 --rotate normal --output HDMI-1 --mode 1280x1024 --pos 0x0 --rotate normal This workaround stop working after the update to 13.04, and now i'm looking for a new solution. Has anyone experienced something similarity? xrandr output: Screen 0: minimum 320 x 200, current 2960 x 1050, maximum 8192 x 8192 DVI-I-1 connected 1680x1050+0+0 (normal left inverted right x axis y axis) 433mm x 270mm 1680x1050 60.0*+ 1280x1024 75.0 60.0 1280x960 60.0 1152x864 75.0 1024x768 75.1 72.0 70.1 60.0 832x624 74.6 800x600 72.2 75.0 60.3 56.2 640x480 72.8 75.0 66.7 60.0 720x400 70.1 HDMI-1 connected 1280x1024+1680+0 (normal left inverted right x axis y axis) 376mm x 301mm 1280x1024 60.0*+ 75.0 1152x864 75.0 1024x768 75.1 60.0 800x600 75.0 60.3 640x480 75.0 60.0 720x400 70.1 lshw -c video: *-display Beschreibung: VGA compatible controller Produkt: G96 [GeForce 9500 GS] Hersteller: NVIDIA Corporation Physische ID: 0 Bus-Informationen: pci@0000:01:00.0 Version: a1 Breite: 64 bits Takt: 33MHz Fähigkeiten: pm msi pciexpress vga_controller bus_master cap_list rom Konfiguration: driver=nouveau latency=0 Ressourcen: irq:16 memory:fa000000-faffffff memory:d0000000-dfffffff memory:f8000000-f9ffffff ioport:df00(Größe=128) memory:fb000000-fb07ffff Thanks for your help!

• Ubuntu 13.04/13.10 - low graphics mode/black screen after login

  - by Richard Stokes

  Since last week, my Ubuntu 13.04 installation started booting up in low graphics mode out of nowhere. I tried a number of solutions found on this site but to no avail. The other night, I decided to upgrade to 13.10 to see if the issue would be fixed in the process. Since then, the system starts fine, but when I login to my account, I'm just presented with a black screen. I switched to the terminal and did any necessary updates, but to no avail. I don't even know where to start debugging this issue, so I'd appreciate if someone could point me towards the first place to start looking?

• Auto completion (using the Tab key) on the new Ubuntu 11.10

  - by Shubhroe

  Earlier, when I used tab to auto-complete filenames (using the tab key) and if the filenames contained blank spaces or certain special characters, the name would be listed with backslashes '\' thrown in so that it could work with a preceding command like ls or rm. eg. Earlier if I had a file name called "The Four Seasons- Spring - Allegro.mp3" and this was the only file name starting with "The", when I typed "rm The" and Tab, it would complete itself to "rm The\ Four\ Seasons-\ Spring\ -\ Allegro.mp3" and I could subsequently press Enter and remove the file. However, lately what happens when I press Tab is the following: "rm The Four Seasons- Spring - Allegro.mp3" and if I now press Enter, it returns a bunch of errors because it thinks I want to remove a bunch of files (named The, Four, etc.). Does anyone else encounter the same problems and if yes, is there a good way to resolve this problem? Thanks!

• How do I create a LiveUSB that lets me install any Ubuntu version?

  - by Dariopnc

  What I'd like to do: have Ubuntu installed on a USB drive and from there install any ubuntu version on a hdd. This is kinda different from using usb-creator because I'd like to have a persistent ubuntu install on the USB drive and not upgrade it every 6 months. From there I'd like to be able to install the most recent ubuntu version. I think it's just a matter of configuring ubiquity, but don't know if this is the case and how exactly do this. EDIT: Let's clarify the persistent thing: suppose I have my USB with ubuntu precise on it suppose quantal is out in the wild suppose that I want to install quantal on the hdd of a computer suppose that I want/can use only the USB drive with precise on it I should erase/upgrade precise on the USB drive to quantal and then install it on the hard drive I don't want to touch my ubuntu install on the USB drive, I'd like to be able to install the newer ubuntu version (quantal) on a hdd from another one (precise) on a USB drive I'd better avoid upgrading the installation on the hdd Hope this helps

  - by Chris Good

  Possible Duplicate: How do I open Deja Dup as root? I am using Ubuntu 12.04 LTS. I'm trying to setup Deja Dup to backup the files for several users (/home) and /etc but as it runs as myself, there are many files it cannot read and therefore cannot backup. I want to try running Deja Dup as root as then it should be able to read and backup all files. I've seen some other info about how to set up a particular App to run as root, so I guess I should try that.

• Sharing samba-folder with root access

  - by Industrial

  Hi everyone, I have a staging server in my network running Ubuntu server 10.10, being my main development area. As I need to access the files in the Apache root from other computers in the network, I have setup samba with the following settings: [www] comment = Apache root www path = /var/www writable = yes force user = root force group = root On the host computer, running Ubuntu 10.10 desktop, I am trying to mount the drive with a bash file looking like below: #!/bin/bash sudo mount -t cifs //192.168.1.5/www /media/www/ -o username=myusername,password=mypassword,rw,iocharset=utf8,file_mode=0777,dir_mode=0777 What happens is that I get mount error(13): Permission denied Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) thrown in my face whilst trying to execute the mount. I've done exactly the same, with exactly the same smb.conf & mount-bash file on another computer in my network, but this just wont work. What am I doing wrong? I am running out of ideas.

• Is file permission secured when it transferred from Ubuntu to Windows?

  - by Gaurav_Java

  I am having 9GB text file which is encrypted . This file contains some confidential data . Which is on my system(Ubuntu) and my external HDD (ntfs) . This file get daily updated and then encrypted . But it has to be shared among 2-3 (Windows) person. I defined permission so that no other person can even read this file(chmod 660). It is too large file, so I can't upload it anywhere and it get updated daily basis. But this file travel on Windows OS and Ubuntu also. Even I am having copy of this on my personal computer. Recently it was deleted by some other user over Windows . I just want to know how can I set permission over that file so that it cannot be deleted from any other operating system. If someone delete this file, then I am having data old for couple of days, which is only on my system. I gone through this question it says there is nothing. And from this question I am not able to understand how can I protect it. Can I do anything for preventing this file from being deleted. Then how can I secure this files from getting deleted any suggestion or software or ideas. Maybe I sound silly or this is stupid question. Please don't close it, thanks for any suggestion or solution.

• How to fix missing menus in non ubuntu maverick apps

  - by piedro

  Hi! There's a bug with the menue of filezilla: When opening filezilla there is no menue list. Very inconvenient because you can't open the "settings"-dialog. There are several workarounds that I tried - none of them really work. change theme while filezilla is running, menue reapperars. Once you close and reopen it the menue is gone again. add "export UBUNTU_MENUPROXY=0" " to .bash.rc or just call it before starting filezilla. Doesn't have any effect for me - menue still missing. tried "sudo apt-get remove appmenu-gtk" cause it's obviously to do with unity but the funny thing is even this method has bo effect at all! How can I fix this? How to do the troubleshooting? thx fior reading, p.

• Menus intermittantly take two clicks

  - by heynnema

  Intermittently, when I left-click on the Applications/Places/System menus, the first click does nothing, and it takes a second click to drop the menu. I've also noticed that hiarchial menus sometimes don't show their expanded menus unless I move the mouse pointer away to another menu item, and then come back into the hiarchial menu. And lately, I've even noticed that in some applications, menus are acting the same way. Any ideas? Cheers, Al

  I am totally trackpoint fan, I use it all the time and have disablet my touchpad. Due to my study I work a lot with MATLAB, but MATLAB uses Java, and horizontal scroll does not be recognized by java as I already reat in many other threats(well it recognizes as right click :S ).

This really drives me crazy. HELP!

• Ubuntu 12.04 desktop, VNC viewer not refreshing screen

  - by user73279

  I've had this issues across multiple machines and multiple versions of Ubuntu desktop (all 10.04 or later). Usually it happens with an old laptop I've put Ubuntu on but now it's happening on my primary dev machine (a quad-core PC recently upgraded to Ubuntu 12.04 desktop). The problem is this - I can connect to the machine and login with the password, the initial screen looks fine but never refreshes. I can see the monitor for the machine across the room and can see the mouse move and the menus pop up but the image of the screen on the PC in front me running the VNC viewer never updates. So the mouse and keyboard commands are working. Ubuntu 12.04 Desktop Ultra VNC Viewer (also seen with RealVNC's free VNC viewer) Desktop Sharing Static IP on eth0; Dynamic ID on eth1 I think it is an Ubuntu config issue because this PC used to work just fine with 9.04, 10.04, and 11.10 (over the past couple of years). I've also had a couple of laptops that used to have this issue with older Ubuntu's but don't with 12.04. Additional info: The Win7 PC I'm trying to use to control the Ubuntu PC is connected via 2 DLink 8-port gigabit routers. The Ubuntu laptop I usually control via VNC is typically only connected to the network via wireless. The screen refresh is choppy but usable. I've repeated the issue on a Win7 laptop which was connected via ethernet and wireless.

• How to change partitioning - may involve conversion of a partition from primary to extended

  - by george_k

  I am having trouble thinking through how I can achieve my partitioning goals. Now my partitions are: sda1 (winA) (primary) sda2 (winB) (primary) sda3 (/ for ubuntu) (primary) What I want to migrate into is (obviously partition numbers need not be exactly like that) sda1 (winA) (primary) sda2 (winB) (primary) sda3 (/boot) (primary) sda4 - extended which will contain sda5 (/home) sda6 (/ for ubuntu) sda7 (swap) I know I may be asking too much, but what would a way to do it? One way I have thought is Create a new primary partition for /boot and split it from the root partition into the new one. It shouldn't be too hard. Then the disk will have 4 primary partitions. Somehow convert the root ubuntu partition from primary to extended. Split that last partition in 3 extended partitions (root, /home, swap) and split the contents there. I am obviously stuck on the 2nd part. Another way could be (maybe easier): Create an extended partition (or two) Split /home there Somehow move everything except /boot to the extended partition. This way /boot will stay on the primary partition that exists now, and will be shrunk as needed, and everything else will end up to the extended partitions. This may sound better, but I'm not too sure how to do the 3rd part. Some details: The disk is almost empty, so I have space to move things around in it, shrink the ubuntu partition etc. I don't want to touch the windows partitions in any way. Reinstallation is not an option. Also using a different partitioning scheme with fewer partitions is not an option (for example not having a separate /boot) Any ideas?
