  • How can the maximum number of simultaneous users to log in to Ubuntu server be increased?

    - by nixnotwin
    I use ubuntu server 10.04 on a fairly good machine, with 2.40 duel-core processor and 2GB RAM. My users login with ssh or samba. I have setup LDAP with PAM to sync user accounts between unix and samba. When I allowed about 90 users to login over ssh at once the server refused login for many users. I am using dropbear as ssh server. Even samba logins failed for many users. I need to allow at least 100 users to login at once. Is there anyway to do this?

  • Eclipse colour scheme is terrible in Ubuntu

    - by cyberjar09
    I have modified my eclipse colour theme to my liking but just cant seem to develop in peace because I keep having to squint and stare at the screen for certain elements. The colour default scheme is simply pathetic! I have no idea what these elements are called and hence instead of attempting to describe them I have attached screenshots. How can I modify these elements to make them more humanly readable?

  • Cursor seems to freeze in the first attempt of typing - Unity 3D, 12.04

    - by Denis
    It happens in the first attempt of typing, no matter is after the startup, or 5 minutes later, or then after. The cursor (or maybe it's the system) seems to freeze, no matter the application I use, taking up 5 sec to appear what is typed. Subsequently, everything is normal, using another applications. @Anwar Shah suggested it could be a daemon waiting to run before the lauching of the first application. Turning off Zeitgest didn't help. It occurs only with Unity-3d. Tested with Unity-2d, everything is fine. Tried to change some Compiz settings, nothing worked, although not tested with every single parameter. Also I deactivated Ati proprietary driver, no effect. My system: AMD E350 1.6Gh, 2G-Ram, ATI graphics - Ubuntu 12.04, 64bits. Update 1: the cursor is blinking normally before I start typing. After the first character (which is not showed), seems to freeze, taking 5 seconds to get normal again. Very annoying, specially when you want to access login sites. Update 2: I tested on a different and old machine (Athlon 64 4800 x2, 4Gb ram, no problems - takes 2 seconds, acceptable. I think it could be related to my specific hardware (Samsung RV415), but not sure about it. Anyone experiencing something similar? Is that what I should expect, or can be fixed or improved? Thanks.

  • add packages to squid-deb-proxy cache

    - by zpletan
    To save bandwidth and data on my Internet plan, I have installed squid-deb-proxy on a desktop, and the client on it and a few other machines I've got. However, based on the post that put me onto this , it sounds like if I take my laptop to a different network and update it there, the downloaded updates will NOT be automatically copied back to the squid-deb-proxy server when I get back on my network. Assuming that this is correct (I will be testing later), is there a way I can stick these packages into the cache so I don't have to download them one more time for other machines in the network?

    - by Ali Unlu
    I have two operating system: ubuntu 10.10 and windows 7 ultimate. I trisected my HDD.One of these is for main Windows files,one of this for ubuntu system and the last drive which must be accessible on both of two system is for common files (musics, films, etc). This last partition is J: in Windows. Unfortunately when I was setting up ubuntu 10.10 while disk partition, I forgot mount my J drive as /windows and accidentally mounted it as swap . Then, I tried to do this visible in ubuntu.But I couldn't myself. Device : /dev/sda4 and whenever I try to do this I always get this error : Error mounting: mount exited with exit code 1: helper failed with: mount: according to mtab, none is already mounted on none mount failed

  • Installing drivers for an ATI 6950 in Ubuntu

    - by aj.esler
    Is there any way to get ubuntu to recognise an ATI 6950? I have tried installing the proprietary ATI drivers, but these do not seem to work properly. It seems to screw up the gnome desktop, and starts booting into terminal. I'm somewhat of a linux newbie, so not really sure whats going wrong. I don't want to game on ubuntu, I just want it to recognise my dual monitor setup rather than mirroring the monitors, so any driver that does this is fine by me. It seems like the open source ATI radeon drivers will not support the 6950/6970 for some time, at least until kernel 2.6.38 is released. The card is also flashed with the 6970 firmware, not sure if this is important. I am running a 64 bit version of ubuntu, I installed ubuntu server 10.10, then installed gnome-desktop.

  • Speaker notification icon

    - by Dreams
    Hi, I hope somebody can help with a minor but rather annoying problem: There is a speaker icon on my desktop and I can't remove it. It has not been there before. I noticed it after I played around with XBMC 10 and a Youtube plugin. The icon shows all the time no matter what application I launch e.g. Firefox, XBMC etc. it just shows on top of the application that I launch. I tried to take a screendump, but the icon is not present in the screendump? I'm running Ubuntu 10.10 (upgrade from 10.04). Hope somebody cant help. Regards Dreams

  • Why does sound stop working after a while?

    - by badp
    I don't know how to reproduce this problem, because I don't regularly play music or sound. All I know is that, sometimes, I'll load a video (from youtube or from a local file) and there will be no sound. Everything looks fine software wise: Rebooting always fixes. aplay, paplay and pals give no error message I'm not in the audio group, as advised The device exists and appears in use: $ lsof /dev/snd/by-path/pci-0000\:00\:1b.0 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME pulseaudi 17313 badp 23u CHR 116,10 0t0 7628 /dev/snd/by-path/../controlC0 pulseaudi 17313 badp 30u CHR 116,10 0t0 7628 /dev/snd/by-path/../controlC0 Restarting pulseaudio or alsa seems to do no good. What is wrong here?

  • Booting Ubuntu 13.10 form USB on server with no OS (Dell PowerEdge T110)

    - by user35581
    I have a Dell PowerEdge T110 (Xeon 1220v2) server with no OS. From my mac, I was able to save the Ubuntu 13.10 for server iso (x86) and used UNetbootin to save the iso to a USB stick (2GB). I was hoping to boot the server from USB, and all seemed to be going well, BIOS even detected my USB drive when I plugged it in, but for some reason I'm getting a "Missing operating system" error. I checked the USB drive and it appears that UNetbootin put the correct files on it form a cursory glance (although I'm not entirely sure what I should be looking for). Should I be able to boot a server with no OS from a UNetbootin created Ubuntu 13.10 USB? And if so, why might BIOS not find the right files? I had read that there is a USB Emulation setting in BIOS, but I haven't been able to find this in the menus. My understanding is that by default, this is set to on. I might try wiping the USB stick and running UNetbootin again. The USB is formatted to MS-DOS FAT16 (should it be formatted some other way?).

  • Ubuntu boots into tty1 after driver downgrade

    - by Zach
    Earlier today I downgraded the driver for my nvidia 240 GT from version 310 to version 304 using ubuntus "additional drivers" utility. After the install I rebooted but instead of opening unity and allowing me to login it booted into tty1 instead. After using the "startx" command I got the message, "nvidia: API mismatch: the nvidia kernel module has version 310.14, but this nvidia driver component has version 304.43." What can I do to solve this? Edit: Solved my own problem by purging all nvidia packaged and reinstalling my drivers.

    So I have solved this issue, but now I have another problem: An unresolvable problem occurred while calculating the upgrade.

  • Problems using custom keyboard layout / symbols file

    - by January
    I have a custom xkb symbols file which looks as follows: // modify the basic German layout to have polish characters default partial alphanumeric_keys xkb_symbols "basic" { include "de(basic)" name[Group1]="Germany - with polish characters"; key <AD03> { [ e, E, eogonek, Eogonek ] }; key <AD09> { [ o, O, oacute, Oacute ] }; key <AC01> { [ a, A, aogonek, Aogonek ] }; key <AC02> { [ s, S, sacute, Sacute ] }; key <AD06> { [ z, Z, zabovedot, Zabovedot ] }; key <AB02> { [ x, X, zacute, Zacute ] }; key <AB03> { [ c, C, cacute, Cacute ] }; key <AB06> { [ n, N, nacute, Nacute ] }; }; The name of the file is depl. I copy the file to /usr/share/X11/xkb/symbols and it works with setxkbmap depl. However, I also tried to add the respective menu entries in the "Text Entry" customization. I have modified the file /usr/share/X11/xkb/rules/evdev.xml and added the following section: <layout> <configItem> <name>depl</name> <shortDescription>depl</shortDescription> <description>German (with Polish characters)</description> <languageList> <iso639Id>ger</iso639Id> </languageList> </configItem> </layout> I have then reconfigured the xkb data with sudo dpkg-reconfigure xkb-data. It works in as much as that the new layout appears as a viable option in the Text Entry dialog, it can be added to the list of dialogs and is visible in the application indicator: However, it does not work, the new symbols are not loaded. No errors are reported in /var/log/Xorg.0.log.

  • Do you know some Information about train travel in China?

    - by user79989
    Me and my friend are planning to China travel next year.well train travel in China is an interesting experience, with the world's fastest train (guangzhou to wuhan), the word's highest train (in tibet) and the world's oldest working train (from Tonglio to Baotou in the north of China). Now travelling in China by train is not always easy.You can do a Hong Kong to Beijing Train trip, and buy those tickets online. But to be honest with you, most of that journey is pretty boring. The best part of it is going through northern Guangdong and Southern Hunan provinces.ChinaTour.com is a reliable China Travel Agency based in USA, which has specialized in inbound China travel for decades.

  • Gnome3 pointer barrier not working with dual monitors

    - by Nathan
    I have a dual monitor setup using Gnome3. Misc Info : In the past I used Fedora, there was a pointer barrier between my two monitors in the upper left corner so that I can hit the hot corner when moving from the right monitor to the left monitor. Problem : However, with my new Ubuntu installation, the barrier no longer exists and my mouse pointer glides straight to the next screen. This makes that hot corner nearly useless. I've looked around, messed with the values in /usr/share/gnome-shell/js/ui/layout.js, but I can't figure out how to make the pointer barrier work. may someone suggest hot to get the full utilization of hot cornet.

  • Best way to cache apt downloads on a LAN?

    - by Ken Simon
    I have multiple Ubuntu machines at home and a pretty slow internet connection, and sometimes multiple machines need to be updated at once (especially during new Ubuntu releases.) Is there a way where only one of my machines needs to download the packages, and the other machines can use the first machine to get the debs? Does it involve setting up my own local mirror? Or a proxy server? Or can it be made simpler?

  • Removing mdadm array and converting to regular disks while preserving data

    - by Jeffrey Kevin Pry
    I have a 6 disk (2TB each) mdadm RAID 5 volume created in Ubuntu 12.04 Server. However, I'm moving to a different solution and want to "unraid" my disks but keep the data. Only 50% is in use. From what I can surmise I basically have to do this recursively for each physical disk. Fail the disk Format the failed disk Move a portion of files to the new disk. Reshape the array Shrink the logical volume md0 This seems like a very time consuming process. Is there an easier way to do this (automatically perhaps) without buying new disks to temporarily hold the data? I am also aware that during this processing my RAID volume will be degraded and vulnerable the entire time. I am not too concerned about this and will be using battery backup and moving the most important files off first. Thank you for your help!

  • Where can I find a 12.10 DVD image?

    - by NMinker
    While I'm open to buying a DVD from the shop, I'd rather download a DVD image, but I can't find it on the Download page (only the CD images and the option to buying a DVD). I have slow internet where I live, I always relied on the Alternative CD. But now with it gone for 12.10, so I looked for alternatives (DVD Image). So where can I find a DVD image, or is the only way to get one is to buy a DVD from the shop?

  • Conky window jumps to the top

    - by Scott Severance
    Occasionally, my Conky window jumps to the top and covers all other windows. The only way to solve it is to kill and restart Conky. This happens at seemingly random times while using Compiz features. It seems especially common while using the scale plugin's window picker, but no plugin consistently causes this problem every time. I've seen several questions that appear related on the surface. However, all those questions are solved by ensuring that Conky starts after Compiz. In my case, my problems occur even if Conky starts after Compiz.

  • HP Envy Beats Edition can play CDs, but not DVDs

    - by Grayson
    After a fresh install, and various other tests (troubleshooting), I have concluded that my laptop (an HP Envy 14 - Beats Edtion) will not play DVDs, however it will play CDs. When I first got the laptop, up until recently it played DVDs perfectly, I doubt there is a hardware issue sees as it loads the DVDs and can view the files in them, but not play them, as well as read and work with CDs perfectly. Was there an update or something of the like that may have caused this? If so, is there a fix? I typically use this laptop 's HDMI out with my TV as a DVD player... so it would be very beneficial if there was a solution to this problem. There was a similar issue with the touchpad that there was a fix for... so I'm hoping that this is something similar

  • Strange sound issues with Ubuntu 11.10

    - by DNA
    I am having strange issues with sound and volume with Ubuntu 11.10 I've noticed very often, especially when I get my computer out of sleep, it lacks sound even though the volume slider is cranked all the way up. But when I plug my headphones in and then take them out, it seems to kick start my sound back! What gives? What daemon in /etc/int.d needs to be restared with the restart command to fix this? I have the following in my init.d folder /etc/init.d/alsa-restore and /etc/init.d/alsa-store Also, my start up ubuntu sound doesn't play either....

  • Keyboard Mouse Problem

    - by Zachary K
    I just installed Ubuntu on my laptop (Core 2 Duo Sony Vaio) and am having a problem with the external keyboard and mouse. When I first logged in the left mouse button does not work, this can be solved by unplugging the external keyboard/mouse's USB connector and then plugging it back in again. But Then randomly other problems happen. (Shift gets stuck, keys don't work etc) The keyboard and mouse are a generic brand wireless (A4 Tech) that I got for cheap. Both work OK under windows so this is a major pain.

  • Unity and games don't work on new Thinkpad T420

    - by Clay Smalley
    Here's my setup: Lenovo ThinkPad T420, brand new NVIDIA Graphics Card 4GB of Ram 128GB Solid State Drive Intel Core i5 Processor Given these specs, there's no reason games and Unity shouldn't be working. The strange thing is that both do work when I run from a live USB, but not when Ubuntu is installed to the hard drive. Is there something different with the 3D capabilities of running from the computer as opposed to running from the live USB? Edit: Some more information: When I log in for the first time when running from the hard drive, Ubuntu says "It seems that you do not have the hardware required to run Unity. Please choose Ubuntu Classic at the login screen and you will be using the traditional environment."
