• How to maintain a SSD drive on Ubuntu ?

  - by Julien Nicoulaud

  I am running Ubuntu 10.04 on a Intel X25-M PostVille 160 Go SSD drive. How can I tell if there's something wrong ? What should/can I do to maintain its performance/health ? Should I use TRIM and how often ? This may look as a duplicate of this question, but I am more asking in term of good practices and learning how to use this new technology the right way...

• Ubuntu 10.04 boot splash screen and themes broken

  - by thezachperson31

  I recently upgraded to the release candidate of Ubuntu 10.04. Since then, two problems have occurred and persisted: the boot splash screen has reduced down to a black screen with random color blocks/text/gibberish at the top; and the themes are broken, as in the light themes have checkboxes in menus the same color as the background, and the dark themes don't correctly change the font colors in the top menu. Help? On a side note, is there a need to upgrade from 10.04 RC to LTS?

  Everytime I open Firefox and go to deviantART, the images usually look like this: Rarely they don't, and in Google Chrome they never show up that way. Is it a problem with Firefox or Ubuntu? I've updated my graphics drivers.

• Ubuntu 9.10 upgraded with Internet connection fail

  - by Neofizz

  I am pretty sure that the latest Ubuntu release does not support my wireless internet card. Everything was working fine in 9.04 and since upgrading my browser will load web pages. I can see and connect to my wep encrypted network. I can ping google.com and lose no packets. I am at the end of my tether, what else can I try? Is it possible to download a driver to re-enable my wireless?

• All tweak settings not saving after last 2 updates?

  - by mawburn

  I am running Ubuntu GNOME 14.04. After the last 2 updates, all settings in the Tweak menu are no saving. It will also not switch to the Gnome Dark theme at all. This includes all Startup Application changes as well as any changes to Extension settings. I'm not sure if I need to include any sort of log records or anything like that, so if you need any more information please ask. I've noticed the default fonts seem to be different. I don't remember that being part of the theme settings. It's almost like I'm running in Safe Mode.

• Why is Ubuntu unmounting my primary hard drive?

  - by Twisol

  I'm running Ubuntu 10.10 on my laptop (an Asus G73j), dual-booting Windows 7 if that matters. After using the computer for couple of hours or so, I get a popup complaining that a file was unmounted, then my GNOME desktop panels disappear. I can't save any unsaved work (the file browser shows "Filesystem" as totally empty), and other programs break in odd ways (like Chrome can't browse to any new pages, but keeps current ones going... at least I still have Pandora to listen to when this happens!). I've tried looking in the system logs to no avail; I'm assuming that it can't write any errors to the logs because, of course, the logs are on the primary hard drives. This started happening maybe a few days ago. Yesterday I upgraded from 10.4, but I believe it was happening before then. Any advice for figuring this out?

• Problems in creating click package for native application

  - by Swordfish90

  Hello everyone I've tried may times to package a native click application mainly following this tutorial: http://notyetthere.org/?p=316 The procedure works and I'm able to execute the binaries both on phones and desktops. The problems start when I install the click package. The application is launched but the game is not working (the "gamefield" is not loaded). The only error message that is given is that versions of localstorages are not compatible (that is impossbile, because it never changed). I suspect that the problem is related to apparmor but I have no proof of that. The source code of the application is available here: https://launchpad.net/ubuntu-netwalk Thank you in advance to everyone...

• Ubuntu 8.04 server is not retaining a static IP address

  - by James Pierce

  I recently setup a linux box running Ubuntu 8.04 (to match another server with 8.04). I need to insure that this box has a static IP address and I changed /etc/network/interfaces to set up the static IP address and when I run sudo /etc/init.d/networking restart it works fine for a while, but always reverts back to 10.0.1.24 after being idle for a while. I also tried stopping/removing the dhcp client, but that didn't help. sudo /etc/init.d/dhcp stop sudo apt-get remove dhcp3-client Here is my /etc/init.d/networking: # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet static address 10.0.1.4 netmask 255.255.255.0 broadcast 10.0.1.255 gateway 10.0.1.1 Any thoughts? Thanks.

• Double default gateway ubuntu server

  - by Elena

  Hi, I've just installed an Ubuntu server 9.10 on an EEEBox. This is my /etc/network/interfaces # The loopback network interface auto lo iface lo inet loopback auto wlan0 iface wlan0 inet static address 192.168.48.16 netmask 255.255.248.0 wireless-essid mynet auto eth0 iface eth0 inet static address xx.xx.xx.xx netmask 255.255.255.224 gateway xx.xx.yy.yy When I restart /etc/init.d/networking, I can access the eth0 ip address from the internet and I can ping the machines in my wifi network mynet. Everything works fine and I have one default gateway. But after some time if I check again the route I just find two default gateways: one is correct and is the previous one, but the other is the one of the wifi network. I have a quite low signal of mynet where my server is and sometimes the wifi just disconnect and then reconnect again. Then I think that this can be a problem and the dhcp of the wifi net, when reconnecting it also add a default gateway. Any idea on how to resolve this issue?

• Ubuntu - changing another users file permissions

  - by Cameron

  I have setup Ubuntu as a development web server - however I am experiencing problems with file permissions. I have 2 users, user1 and user2, and they both have been put into the group www-data. I have uploaded a new file with user1 so the file is owned by user1 and the www-data group. At present if user2 wants to modify the permissions on that file to say 777 - they cannot. Is there a way to allow any users within a group to be able to modifiy permissions etc.. on this file? I have tried changing umask to 002 and a few other combinations that were suggested without luck.

• No sound (USB speakers) in Ubuntu 9.04 Jaunty Jackalope

  - by Mike

  I just installed Ubuntu 9.04 and have been unable to get sound functioning. I have a set of USB speakers (not USB powered with a stereo plug... they are totally USB). I've tried plugging them directly into the tower as well as into the USB port on my Dell 2405FPW monitor. Both USB ports are functioning correctly (I tested by sticking a flash drive in there - they both read it), and the speakers are functioning correctly in Windows. If it's relevant, I have an SB Audigy 2 sound card that came with the computer, but is not being used. Any ideas? Thanks! EDIT: These are the speakers - Logitech S-150 USB Speakers

• Apache restart on Ubuntu - error “could not bind to address 0.0.0.0:80”

  - by william

  I'm a n00b - trying to get apache2 set up on Ubuntu 9.10 (Karmic Koala) on Rackspace Cloud. I have set up/configured OpenSSL and installed Apache, but Apache won't start. I assume its a misconfiguration in my /etc/apache2/sites-available/ssl or /etc/apache2/sites-available/default files) When I try to restart apache using the command: sudo /etc/init.d/apache2 restart I get the following error message: [error] (EAI 2)Name or service not known: Could not resolve host name *.80 -- ignoring! [error] (EAI 2)Name or service not known: Could not resolve host name *.80 -- ignoring! (98)Address already in use: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down Unable to open logs ...fail! For my /etc/apache2/sites-available/ssl I have used a virtual host of *:443. For my /etc/apache2/sites-available/default i have used a virtual host of *:80

• Machine freezes when configuring dual display on Ubuntu 9.10 (karmic)

  - by sa125

  Hi - I'm trying to configure dual displays on an Ubuntu 9.10 machine. When I connect the 2 screens (1 VGA input, the other DVI), I see them in a mirrored display. I opened up Display Settings and unchecked the 'mirror screens' box, and when I clicked apply, the machine froze and I had to force restart it. This happened repeatedly for about 6 times until I gave up. How do I set it up to boot up normally with dual display working? thanks. edit: I thought it might be related to the virtual screen size, so I tried to edit /etc/X11/xorg.conf to add: SubSection "Display" Virtual 2560 1024 EndSubSection But that didn't do much. Each screen works fine on it's own, and together with mirrored display.

• No External Network Access Through Ubuntu VPN

  - by trobrock

  I have setup pptpd as my VPN server on Ubuntu Server 9.04, I am able to connect to the VPN from the client and can access the server's local network, but I am unable to connect to the external network via the VPN. If I login to the server via SSH: $ ping google.com PING google.com (74.125.67.100) 56(84) bytes of data. 64 bytes from gw-in-f100.google.com (74.125.67.100): icmp_seq=1 ttl=49 time=65.9 ms 64 bytes from gw-in-f100.google.com (74.125.67.100): icmp_seq=2 ttl=49 time=63.2 ms 64 bytes from gw-in-f100.google.com (74.125.67.100): icmp_seq=3 ttl=49 time=63.9 ms 64 bytes from gw-in-f100.google.com (74.125.67.100): icmp_seq=4 ttl=49 time=66.0 ms If I connect to the VPN and ping locally: $ ping google.com ping: cannot resolve google.com: Unknown host I have a feeling it is some routing issue on the server but I am unsure.

• VirtualBox / Ubuntu 10.04 Server

  - by SevenCentral

  I created a virtual machine using VirtualBox 3.2 and Ubuntu Server 10.04 x64. Everything works fine. I logged in. I mounted the VBoxGuestAdditions.iso file. However, I can't for the life of me find where in the operating system this was done so I can get the additions installed. I've tried /media, /cdrom, /mnt, etc... I'm obviously new at this. Can someone help figure out how to install the guest additions and how to locate the mounted file? Thanks.

• set up pernament ramdisk in ubuntu to not using ram when is the ramdisk empty

  - by robo

  Hi I've got 8GB RAM on my laptop running Ubuntu 12.04. I added following record to /etc/fstab tmpfs /media/ramdisk tmpfs defaults,noatime,mode=1777 0 0 What exactly it means? I have tested that I can save 4GB to ram disk at most. Why exactly 4GB? Where did the computer get this number from? And what happens when I don't use that ram disk for a while and when the directory /media/ramdisk is empty? Does it mean that my system can use whole 8GB ram? And what happens when the system runs out of ram? Will the most rarely used things be moved to swap? And should I turn of swap if I think my system will never need it? Will turning off the swap make my computer faster? And can I even remove the swap partition? And will the hibernation work correctly then?

• Error burning DVD using Devede on Ubuntu 9.04

  - by tim-myers

  I'm trying to burn a DVD in DeVeDe under ubuntu -- on my computer it's already in DVD format (a VIDEO_TS folder) but when I try and drag it into DeVeDe it says "Some files weren't video files. None added." From looking at it, all the files look like they belong there, just from doing this a few times already and seeing all the files contained in a DVD. The file extensions in the folder are: VOB BUP IFO and the files are all named like VTS_02_1.VOB. I have tried excluding the IFO files when dragging them into DeVeDe but get the same error. Is the problem in the types of files in the DVD data or is the DVD corrupt?

• Sharing files from Ubuntu to Mac

  - by seengee

  Hi, Running Ubuntu 10.04 in one office and we want a couple of Mac's in another office to be able to connect to shares on this computer. Want a fairly simple solution to this if one exists. Started looking at setting up a VPN using PPTP but it seems quite complicated. Also seen mention of VNC but this seems more related to sharing desktops and all i want to do is share a directory. Could i just install open SSH and have the Mac users mount a share over SSH using public/private key encryption?
