• Problem with Ubuntu and UEFI (Problem with any linux OS)

  - by K.T.Sumant

  I have purchased a new Sony Vaio laptop and it is said that the Windows in the recent laptops is installed in the UEFI mode. But all the Linux OS are installed in default in Legacy mode. When I reboot my laptop, Ubuntu is not being detected on boot. Only Windows is detected. To access Ubuntu, whenever I boot the system, I need to: (1) enter the boot menu, (2) change the mode to legacy, and (3) type a bit of scary commands in grub then Ubuntu successfully opens. This is a bit of problem for me. So I wanted to know the solution for this problem. So please kindly look over my problem as soon as possible.

• How can I maximally compress .gz files in Nautilus?

  - by Takkat

  When selecting Compress... from the right click context menu in Nautilus I am able to quickly compress files to .gz format. However by default Nautilus does not use maximum compression. Can I make Nautilus to use maximum compression like gzip -9? Using gconftool or gconf-editor to set the compression_level for File Roller to maximum seems right but infortunately has not the desired effect and will not lead to maximum compressed files. As this is the expected way of how to set compression levels a bug report has been filed upstream. Any ideas for a workaround are welcome.

• After update, audio won't play throw hdmi cable

  - by ckhenderson

  Yesterday (June 7th) I faithfully updated a bunch of stuff through update manager (though I'm not sure what since I never read what I updated any more because I'm a bad person). Afterward, I discovered that I could no longer play audio through my tv via HDMI. The sound settings menu seems to have completely changed and the shell script that I wrote a week ago (with much pain and effort as I had never before written a shell script) to toggle between my laptop speakers and the HDMI cable output no longer works. When I type in pactl set-card-profile 0 output:hdmi-surround in the command line I get Failure: No such entity Presumably this means something with Pulse Audio changed but, while I'm learning a lot about the inner workings of Ubuntu/Linux, I'm not an expert and would love some help. EDIT: So I noticed that pacmd set-card-profile 0 output:hdmi-stereo seems to get everything working. Still, shouldn't there be a way to do this through the GUI as well?

• XNA - Debugging/Testing Individual Sprites and Pixel Collision

  - by kwelch

  I ran through the first training on XNA where you make a shooter game. They did some thing that I would not do and I want to use their starting point to learn more things. I want to try better collision and adding a menu. I saw something online with the sonic physics where they have a frame by frame of sonic moving 1 pixel. See picture below. I am new to development, but I have been programming for years now. What would you guys suggest to try these different things out. How would I simulate a similar frame by frame testing as they do in the above picture? Thanks!

• How much localizations is too much for a game?

  - by Krom Stern

  We are making an RTS game and we intend to add localizations to all languages our players use. So far we have 16 locales and about 3-4 are being planned. Now some crazy ideas pop up from our community, players ask for "funny text" localizations. We have been already offered a pack that makes it for 1 of our languages. Now I was thinking where should we draw a line between official localizations which we include into the game and unofficial mods that players will have to install on their own? Obviously overcrowding locale selection menu with all sorts of funny locales (LOL-cat, redneck, welsh, medieval, simplified, etc.) for all the languages seems way too much. But is it really? What are the hidden pros and cons of having too much locales and how much is too much?

• Why do I get "No root file system is defined" when I try install in one partition?

  - by Emilio

  The thing is that I have 3 partitions on my computer. /dev/sda1 Type: ntfs (size 104MB; 35MB in use) [This is Windows Loader] /dev/sda2 Type: ntfs (size 144598MB; 64536MB in use) [Here I want to install UBUNTU] /dev/sda3 Type: ntfs (size 105353MB; 20227MB in use) [This my backup partition I don't wan't to delete anything from here, I have all my necessary information] So the problem is when I select "Device for boot loader installation" "/dev/sda2" Pops out: "No root file system is defined. Please correct this from the partitioning menu." How can I resolve this? :)

• 11.10 had sound, 12.04 doesnt. Acer Aspire One D257

  - by Jeff Welling

  I'm wondering if anyone else has had this same problem, because if so it might be worth while for me to file a bug, but it might also be chaos monkey so I wanted to check first. I have an Acer Aspire One D257 and the sound worked in 11.10 by default, but after doing a fresh install of 12.04 there is no sound. There used to be a speaker icon on the menu bar but now there isn't, and volume up and volume down hotkeys now do nothing, which leads me to believe it isn't detecting the sound card properly anymore. Googling for sound problems on an Acer Aspire One D257 on 12.04 isn't showing any helpful results, so I'm wondering if it's just me. Does anyone have an AAO D257 on 12.04 with the sound working, and if so did you have to do anything special to make it work?

• Closing lid does not suspend laptop

  - by fgysin

  I'm on a Lenovo T400 laptop. In the past I had suspend problems on every second version of Ubuntu (at least it feels like it), but in 11.04 it was working perfectly. Now, after the upgrade to 11.10 closing the laptop lid does no longer initialize suspension. When I choose 'Suspend' from the shutdown menu it works perfectly, so this does not seem to be an issue with suspend itself. The options in System Settings>Power are of course set to suspend in case of closing the lid (both for battery and AC poer). Note: I have no idea if this is of any importance, but I'm running the gnome-session-fallback stuff, as I just hate the Unity desgin.

• 12.04 - why does the network icon dissapear every time my machine is turned off

  - by Howard Walker

  After spending an hour or two working out how to find the network Icon, I find that when I reboot the machine, I have to go through the whole procedure again. 1. The network menu is not there - so first I have to find the terminal. This has no particular location that I can find but usually I have to type terminal in the dash. 2. Then I have to type nm-applet in terminal 3. The network manager icon then appears, but only works if the terminal window remains open. Shut down the terminal window and the network disappears. This is a pain - plus I have to type my password in every time, which is another waste of time, thought this has always been a problem. So can anyone tell me how to make the web automatically connect at startup without any intervention from me.

• Menus and text boxes look graphically corrupted in 12.10

  - by Stanton.Sculpture

  If I let my computer run long enough the screen gets glitchy or graphically corrupted only in certain areas i.e. in text related boxes, menus, menu bars, scroll bars, the system monitor window, etc. It becomes difficult to read what I am typing. Its been happening quite often and I can only fix it by restarting the computer, but its only a matter of time before it happens again. Don't know what else to do, its been a thorn in my side for quite some time now and I need a fix soon because its only gets more frequent until I'm rebooting my computer five times a day. I attached a picture of what happens to this bug report: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1083474 I know I can repeat this bug but I don't know how to catch it and document it. Any help would be greatly appreciated. Thank you

• Doesn't suspend when closing lid on a Dell Inspiron N5110

  - by AWE

  This is what advanced settings tell me: Shell Laptop lid close action on battery suspend Shell Laptop lid close action when on AC suspend I couldn't post a screenshot because "new users aren't allowed to post images. Earn more than 10 reputation to post images" The screen is on when I open the lid after closing for a few seconds. But not when I suspend from the session menu. Still the battery on my Dell inspiron N5110 is always empty when I get back to it after closing the lid. 'Why' is my question.

• Skype on 12.04 x64 does not start even after purging and reinstalling it

  - by Zevaka

  I am wondering if there's anyone here who managed to use Skype on 12.04. It used to work (ever since I first tried Ubuntu 10.04) flawlessly, but after upgrading to 12.04, it just doesn't start. If I start Skype from terminal, it just says Segmentation fault (core dumped). I tried to remove Skype and installed it from different locations: Skype website (did not install at all, "package error") From official Ubuntu repository (doesn't start at all, segmentation fault) From repository "deb http://archive.canonical.com/ $(lsb_release -sc) partner" (doesn't start at all, segmentation fault) Interesting thing: even if I remove / purge Skype from the system, it still shows up in Unity menu (of course doesn't start). Any help here?

• Aliasing resellers domain to primary domain

  - by Ashkan Mobayen Khiabani

  I have designed a website that accepts re-sellers and actually the concept of this website is having local re-sellers for each province (or should we say branches). I have designed this website in a way that anybody who has a domain, can point to our website (a record or cname). well most of the website content are the same, the only difference is that re-sellers website doesn't have some items on the main menu and may have some small descriptions of their own branch in some pages. I read that Google may ban websites with duplicate content (or which are significantly similar). I want to know will this be a problem for me? If yes, what else can I do? we have had considered asking our reseller to use iframe that loads our website but wanted that each reseller can have its own SEO and try harder but what I read about this duplicate thing worries me.

• Why does nothing work after I randomly changed some file permissions?

  - by Josh B

  Ok so last night i was trying to set permissions to some folders in my File System, since apparently im not an admin on my own computer. And now everything got messed up today and i don't know what to do.. I lost my internet, the icon is not showing in the taskbar anymore. I lost my sound, there is no sound devices listed when i go into the sound menu. I can not log into root anymore, it gives me "sudo: must be setuid root" I can not plug anything in anymore, it will not recognize flash drives or external hard drives. It gives me a Internal Error message everytime i log in It doesn't let me log into the Grub screen anymore on boot up. What did i do? I have a lot of files on here i wish to put on a flash drive but it won't recognize it.

• Font displays differently in Firefox vs. Chrome

  - by Goro

  It seems that my menu bar is displayed with a different font stretch in Firefox than it is in Chrome. See the following: Here is the CSS applied to this element: font-variant: small-caps; font-size:13px; letter-spacing: 0px; font-family: Arial; font-stretch: normal; text-decoration: none; As far as I can tell everything regarding that font is exactly the same, yet they still display differently (see pic). Any ideas? Thanks,

• How to change icons of specific file types on Ubuntu 11.10?

  - by Curious Apprentice

  I want to change file icons of some specific file types like- .html, .css etc. I have tried using "File Type Editor (assogiate)" which is not working. I have also tried using "Gnome Tweak Tool" using icon themes. But that also does not worked properly (Though I can change folder icons , dash menu icons but not file icons). Please suggest me a way so that I can change file icons properly. I have read some of the articles saying about some mime type changes. I could not get proper guide from any of those articles. If there is such a way then please write in detail. Many Many Thanks in Advance :)

• Partitions and cdrom are not mounted, and the bars are missing in Ubuntu 12.04

  - by nuit

  Provide my spec and sorry for my poor English first. MB: Gigabyte G31M-S2L (bios ver. F9) CPU: intel E5200 2G RAM HD1: WD 160G with 2 partitions (partition 1:60G, NTFS, win xp; partition 2:100G, NTFS) HD2: WD 320G with 2 partitions (partition 3:220G, NTFS; partition 4:100G, ext4, Ubuntu) Recently, I tried to install Ubuntu 12.04 Beta 2 on my desktop PC (on partition 4). At the beginning, everything looked great including the auto-mounting of partitions 1~3 and the unity (3D). However, after I deleted and re-allocated the partitions on HD2 and re-installed Ubuntu on partition 4, the partitions 1~3 are no longer auto-mounted when I logged in the desktop (and even the inserted cdrom would not be mounted either), and the launch bar and menu bar in unity (3D) are missing. The configurations during these two installations are all the same as default. Are there any possible reasons or solutions for this issue? Thank you in advance!

• Higher screen resolution in VirtualBox?

  - by pelms

  I've just installed Ubuntu 10.04 into VirtualBox on Windows 7. Unfortunately the only options showing for screen resolution are 640x480 and 800x600 and the monitor is showing as 'Unknown'. How would I go about upping the resolution to 1280x1024 (I'm on a 1600x1200 monitor)? Update I tried mounting the VirtualBox 'Guest Additions' ISO (from the VBox 'Devices' menu) and doing sudo sh ./VBoxLinuxAdditions-x86.run from the mounted drive, which gave 2 new listed resolutions after a reboot (1024x768 and the 16:9 version of that resolution). These worked when I selected them but disappeared when I switched back to another resolution. I tried rebooting and running VBoxLinuxAdditions-x86.run again but onlu the 2 low res options listed this time. I think I'm going to reinstall... Seems to be a VBox problem rather than an Ubuntu problem as after reinstalling 10.4 overwriting the original virtual partition, sudo sh ./VBoxLinuxAdditions-x86.run now has no affect at all.

• What to do when Ubuntu 13.10 64-bit does not boot?

  - by Anonymous John

  Ubuntu 13.10 will not boot, it won't even show the grub menu or Ubuntu booting. There is just a purple screen for 20 seconds then a black screen, then the screen says entering power save mode. here are my system specs:Intel DQ965GF Motherboard (OS independant), Intel core 2 64-bit, 12GB HHD (SATA), 200GB HHD (SATA, installed here), 250GB HHD (SATA, Encrypted with LUKS), 3GB DDR2 RAM (DIMM 0 A 1024MB,DIMM 1 A 524MB, DIMM 0 B 1024MB, DIMM 1 B 524MB),2 Rewritable DVD drives (one SATA and one IDE), small floppy drive and car reader, and AMD gallium 0.4. That's all I know from the top of my head, I have no OS to give me more info on the graphics card, but all Ubuntu OSs worked on my PC from 12.04-13.04 just fine. Does this mean will never be able to use Ubuntu 13.10? I think I am screwed.
