Ubuntu 12.04 LTS 32bit does not detect 4Gb ram

I have recently installed 4Gb of ram for an existing 12.04 32bit Ubuntu.

MP4 files show up but won't stream to xbox 360

- by Greg

I set up a basic media server to stream to my 360 using uShare. Here are the instructions I used: http://linuxexpresso.wordpress.com/2011/01/02/howto-ubuntu-upnp-server-to-xbox-360/. I can stream avi files fine but I cannot stream mp4s. When I go to videos on the xbox, I can see all of the videos and folders but when I click play for an mp4 nothing happens. On my ubuntu desktop I can click on the mp4 file and it plays fine. And if I take that file, stick it on a thumb drive and plug it directly into the xbox the mp4 will play off the thumb drive. I'm lost for why it won't work through ushare. Any ideas?

Flash completely freeze computer

- by Yanick Rochon

Since this morning, and ever so frequently, Flash will completely freeze the computer as soon as something launches it. First, the web page will stop responding, then the entire browser, and after about 2 seconds, the mouse and keyboard will stop responding and the computer will escalate to 100% usage, and all that's left is to perform a hard reboot. I tried re-installing Flash, downgrade my kernel, nothing will do. I'm running Mint 13 64-bit (based on Ubuntu 12.04) with XFCE (not Xubuntu, I installed XFCE as separate package). It never freezes otherwise, so I know it's caused by Flash. How do I solve this issue? What could cause this?

Firefox 11: Adobe Flash not being recognized on certain websites

- by Feuerfotze

I have Adobe Flash Plugin v11.2r202 in Firefox 11.0, on Kubuntu 11.10 64-bit. Flash works flawless on Youtube. However, certain websites claim that I need a more recent version of Flash Player. That is, of course, a wrong assumption. Because I have the latest version installed. Also, I tried Firefox add-on "flash aid". It didn't help. For example, on this website: http://htwins.net/scale2/ It says "You need a more recent version of Adobe Flash Player." Whereas in Chromium or Opera, it works. What is the problem there?

Use Network-Manager to Connect to a wifi Access Point on the command-line

- by Stefano Palazzo

I'd like to connect to a wireless access point from the command-line. ideally, I'd only need the name of the AP. But the hardware-address would work as well. I know I can use nmcli to connect to a managed network connection, but in my case, the access point may not be configured for Network-Manager yet (See the difference between the output of nm-tool and nmcli con). Example output of nmcli: Auto pwln 3a3d62b1-bbdf-4f76-b4d2-c211fd5cfb03 802-11-wireless [...] Wired Network aa586921-accf-4932-98c4-c873c310f08e 802-3-ethernet [...] Cisco-UDP Uni 7f94847b-04dc-40b7-9955-5246fb77cc65 vpn [...] T-mobile (D1) 867f345a-cbbf-4bd4-b883-a5e5ae0932f0 gsm [...] Example output of nm-tool: State: connected - Device: eth1 [Auto pwln] ---------------------------------------------------- [...] Wireless Access Points (* = current AP) *pwln: Infra, [...], Freq 2472 MHz, Rate 54 Mb/s, Strength 80 WPA WPA2 WLAN: Infra, [...], Freq 2422 MHz, Rate 54 Mb/s, Strength 20 WPA WPA2 [...] How do I connect to an access point that may or may not be known to NM? Extra: Finding out if the connection needs a pass-phrase, and submitting it on the command-line as well would be great too (that is to say It'd be nice if network-manager wouldn't pop open any keyring dialogues or errors on the gui)

How to change eclipse font sizes

- by David M. Karr

I'm trying to reduce the font sizes used in Eclipse. I've read several notes talking about how to do this, but none of them have made a difference. Obviously, changing it in Eclipse preferences doesn't do it. The common answers about using "Appearance-Fonts" doesn't work, because there is no "Fonts" tab. I believe I saw one person say that the "Fonts" tab isn't supposed to be there anymore. The next suggestion is to install MyUnity and change the font settings there. That appeared to change the fonts used in other apps, like gnome-terminal and window headers, but it still has had no effect on Eclipse.

Ubuntu 10.10 Network Issues (wireless as well as wired)

- by user9054

down vote favorite Hi Friends, I have got this issue with Ubuntu 10.10 . I have been with ubuntu 8.04 and then decided to try out ubuntu 10.10 . I booted with a LiveCD and was able to configure the wireless network painlessly using the livecd . so happily i installed ubuntu 10.10 . As soon as ubuntu came up it detected the wireless network and i was able to assign a static IP to eth1 (i dont use DHCP option on my ADSL router) and enter a wap key and use pppoeconf to configure the dialer . The net was on and i was able to surf the net . all hunky dory so far . However on the next boot the fun started . It did not detect the wireless network . I could not see the network manager icon in the systray . I used ifconfig and saw that the entry for eth1 was missing .I used ifup eth1 and it said that eth1 was already up . Then i installed wifi-radar . Wifi-Radar detected the wireless network . I configured wifi-radar for the detected wireless network , set the wap driver as wext and used the manual IP settings . However on clicking connect wifi-radar started looking for a DHCP IP , needless to say it failed . For the love of god i cannot understand why wifi-radar is using DHCP when i have specified manual settings . Next i decided to use the wired network to surf the net looking for a solution . So i plugged in the network cable from my modem , it detected the plugged in connection , i configured eth0 , used pppoeconf and connected to the net . Then i foolishly decided to reboot my PC . And wonders of wonders , the same problem appeared . I cannot see eth0 in my ifconfig anymore . i used pon to start the dsl-provider connection and it said something about network error or something . Now my ifconfig shows only lo , both eth0 and eth1 have disappeared .Can anybody help me on this ? Is it a problem with ipv6 , if so how do you disable ipv6 on ubuntu 10.10 ? OR is this is a known issue with ubuntu 10.10 ? .PS : 1) i tried linux mint 10 and had the same issue . on rebooting wireless network was not getting detected . 2) i have made myself the administrator so that there is no issue of rights or anything. Any help is appreciated.

Ipod scrobbling to last.fm?

- by Crud Mucosa

The Amarok 1.4 series scrobbled the songs I played via ipod (and also had great ipod song transfer functionality). I've not been able to scrobble songs played via my ipod then synced to a media player since my upgrade to 11.10 (and the subsequent total loss of Amarok 1.4). I see various media players (clementine, banshee) have requests in for this feature but I'd like to believe that something, somewhere has ipod scrobbling in Ubuntu! Was the 1.4 series of Amarok the only thing that had it? Good music management is one of the main reasons I've used Linux (besides stability, clean interfaces, ease of development, etc). The lack of ipod scrobbling to last.fm makes me a very sad panda.

Firefox profile issue

- by vooda gopal

Is there any limit in the number of firefox profiles that can be created? My issue is I am currently doing selenium webdriver automation in linux for a device. There are 50 devices of same kind and framework will pickup a device depending on availability. I need to by pass unsigned ssl pages. I am using firefox 14. I have implemented following but it is not consistent. everytime a device is chosen adds cer of device to the cert file in firefox profile but I am getting sec_error_bad_signature very frequently. So I started recreating cert [delete and create if by opening firefox] file for every run. Now this is posing a problem if multiple devices are run at the same time. Hence I want to create separate firefox profile

Ubuntu 12.10 loud fan noise hp compaq 615

- by Levente Nagy

I am totally new to Linux, i installed it yesterday, since than i my fans are really loud, i did not have this problem on windows. I saw this post on this site How to control fan speed? But i am totally lost with it because im a new user to Ubuntu when i arrive to that page i see these lucid (utils): utilities to read temperature/voltage/fan sensors 1:3.1.2-2: all precise (utils): utilities to read temperature/voltage/fan sensors [universe] 1:3.3.1-2ubuntu1: all quantal (utils): utilities to read temperature/voltage/fan sensors [universe] 1:3.3.1-2ubuntu2: all raring (utils): utilities to read temperature/voltage/fan sensors [universe] 1:3.3.2-2ubuntu1: all saucy (utils): utilities to read temperature/voltage/fan sensors [universe] 1:3.3.3-1ubuntu1: all trusty (utils): utilities to read temperature/voltage/fan sensors [universe] 1:3.3.3-1ubuntu1: all So what is lucid? trusty? saucy? and other? i thought its some kind if a ubuntu type (sorry for beeing silly here) i checked my ubuntu version it just says Ubuntu 12.10 So which one i need to download? I saw there are terminal commands, im new to that too, will it cause some problem if i just copy and paste? PS: I saw my graphics card is undetected as well i have a ATI Mobility radeon HD 3200, could that cause the problem too?

Keyboard Bug or feature on Ubuntu on a MAC?

- by ProfeDiego

I have ubuntu 10.04 on my mac, and i have realized that when i pluged in an USB keyboard (PC) and turn on the numeric keypad if then i removed the keyboard, the keyboard on the mac (this sounds odd, not english spoken person sorry) is completely lost. Let me try to explain, when removing the USB keyboard with the numeric keypad activated, the built in mac keyboard is mapped like a numeric keyboard ONLY, j=1 k=2 l=3 u=4 ... and so on, and the others keys doesnt work, and the only way to restore normal behaviour is connecting the USB keyboard and turn off from there the numeric keypad, and then removing the usb. Is this behaviour ok? Is this a feature or a bug? Macbook 4.1 regards

Can I let maximized windows reach behind the gnome-panel?

- by Bruce Connor

My top gnome-panel is set to not expand and sits on the top-right of my screen. I just realized I wouldn't mind if maximized windows were able to get behind it (it wouldn't actually cover up anything). Is it possible to achieve that with the gnome-panel? Here's what it looks like now: Ideally, the window's titlebar would be behind the panel (partially obscured by it). I know that different dock softwares like AWN are able to do that, but I'm running a weak netbook, and I would rather do that with the gnome-panel.

How do I get my ART USB Dual Pre preamp to work?

- by Zach

I am using Audacity. I have an ART USB Dual Pre preamp. Ubuntu is not recognizing it whatsoever. I am able to record in Audacity, but it is using the mic that is built into my computer (which is a compaq Presario CQ50) instead of the one plugged into the preamp. How do I get Ubuntu to recognize the preamp that is plugged into my computer? Something tells me it has to do with the installation of the preamp software. It came with a installation CD, but when I go to "install", the nothing happens. I can view what is on the CD, but there is no installing of anything. Please help!

Problems with icons and shutting down Ubuntu 12.04

- by Anders

I recently upgraded from 11-10 to 12.04 as a dual boot (Windows 7) and am having problems with shutting down. I installed from a CD that I burned from the iso file, and to get it to boot from the CD, I needed to install the special help program from Windows that would then recognize the CD as the system booted.The installation gave me my own user account as well as a guest account. For the User account there is no "gear" icon (in the upper RH side) from which to access the shut down menu. Interestingly the icons for the Home folder, the Ubuntu One folder, and the System Settings folder are missing, although there are blank places shows these names if the mouse cursor is positioned over these areas. They will even launch with the press of a key - but no icons are visible. For the Guest account, all of these icons are visible and usable. The problem that occurs in shutting down is that I need to leave the User account, move to the Guest account (so that I can access the top right "gear" icon that has the shut down menu item) and press the shut down button. The problem here is that when the shut own menu appears and I press the confirmation that I wish to shut down the computer, the page blanks (as one might hope in the process of closing down), and then pops up with the log in menu, giving the option of logging in as a User or as a Guest. So the questions are: 1) how do you reinstate the far right top icon from which you can access the shut down drop down menu in the User account page. 2) how do you get the icons to display properly on the Left hand side (Home, Ubuntu One, System Settings, and Workspace Switcher) 3) how do you get the system to turn of when you press the shut down button! Boy oh boy! Thanks a bunch for any help!

Ubuntu Server Read-Only Filesystem Issue

- by Scott Deutsch

We are running a virtual machine server with multiple virtual machines with ubuntu server edition 12.04 and every so often (usually after updates via webmin it seems), the hard-drive turns into read-only filesystem. Only two of the virtual machines get affected by this problem (that I noticed so far). What could be causing this issue? What could we try to fix this problem? Has anyone else had this problem before? If so, what did you do to fix it? If I use Aptitude instead of webmin, it will not turn into into a read-only filesystem. Though this could be a coincidence. Could it be a webmin issue? Thanks. UPDATE 1 Looks like this is not an update/webmin issue at all. How I know this is because one of the virtual servers is a git server and it turned into a read-only filesystem out of the blue today. With this new info provided to you, what should I try? Thanks.

Boots up into Terminal

- by Jacob Larson

I am running a 64 bit version of Ubuntu 12.04.1, and I when I boot up, I am thrown (Rather violently. :P) a full-sized terminal, instead of my lovely GUI login screen.. So I looked around and tried the "startx" command, which works like a charm. Only problem is that now, I have no clue how to keep it from booting to the terminal every time, and boot up into the regular GUI with all my stuff. I did install some kernel updates the night before, though I restarted my computer twice after I had done so without a problem. Thanks for your time!

Is /home encryption useful on a server?

- by Dennis

I've got a question about the use of encryption: I set up a Ubuntu 12.04 server to use it as a router, file server for backups and webserver. Of course, it is probably not the best idea to put backups on the same system as a web server, but it is only for private usage and I don't want to spend too much money. So I thought it is not a bad idea to set up /home-encryption for the backup-user-account with which I do my backups. But in the same moment, another quesiton arises: Does it still makes sense? Via SSH, root login is disabled. And access to the /home-folder of that user is reduced to the user itself. So the only scenario to access the /home-folder is to connect keyboard/display to the server, login as root and change to /home. Or have I overseen a scenario? In case I am right, you can only access the /home-folder from "outside" as the backup-user. But than, encryption also doesn't make sense anymore. Am I right about that thoughts? Or do you still see a way to access the /home-folder of the backup user so that encryption still makes sense? Thanks for your help in advance!

Weird font hinting in Firefox 4

- by sexyprout

Hi everyone. I know this a recurrent topic but I just can't find a decent solution--although I found one for Chrome. Just take look at the following screenshots: Chrome 9 Firefox 4 See the slight difference? I can't identify the exact difference but I can tell fonts in Chrome look smoother. Here are my system preferences (prefer to show a screenshot as I don't know the exact translations in English): Anyone got a solution? Thanks. Update: from my point of view, it doesn't seem to actually be a hinting problem. I'd say Firefox uses subpixel rendering instead of grayscale rendering. (yet I can't find the setting in fontconfig) But this is a subjective opinion, can you confirm?
