• How to grub-install ignore specific drive/partition

  - by gsedej

  Is it possible to use grub-install or update-grub to just search on specific disk/partition? (or ignore specific)? I installed Ubuntu 12.04 on my hard drive, but i wished to do some testing on it without harming current installation, so I "rsynced" root partition (the only) to the USB partition (ext4). I did fix /etc/fstab on USB partition. The problem is that when I do grub-install /dev/sdb (usb) GRUB seems to confuse when UUIDs. Whatever I chose in GRUB it always boot from disk. In grub in edit mode I see that in two "UUID" lines are not the same. If I retype UUID from "first" to second "line" it boots from USB (as I wish). Is there any other way than fixing /boot/grub/grub.cfg each time? EDIT: the GRUB generated good when I booted from USB and grub-install from there, but question is still if it's possible ignore drives

• Need to adjust touchpad edge scroll area

  - by MikeVB

  I have an Acer Aspire that I have dual booting XP and Ubuntu. On the Windows side, the driver allows you to set how close your finger has to be to the edge of the touchpad before it goes into scroll mode. In Ubuntu I don't have the option (at least in the GUI) to change the scroll area on the pad. Is there a conf file or other way to change this? I'm constantly getting into the scroll area during normal usage. I would like to leave it on without losing so much pad area to the scroll feature. Thanks a lot.

• How do I get to the maintenace shell?

  - by Narida

  I'm asking this because initially, my problem was this (power failure during installation, so I typed the following instructions in the maintenance shell: sudo mount -o remount,rw / sudo dpkg --configure a sudo mount -o remount,ro / sudo sync sudo reboot The first three lines worked, afterwards, my computer (a Dell Inspiron 530) got stalled for several hours, so I unplugged it. When I turned it on, the log in screen appeared, and after I try to write my password, it leads me back to the log screen. I must note that when I typed the first three lines during the maintenance shell mode, it said that the errors which were encountered during processing were: initscripts bluez gnome-bluetooth So, what do I have to do in order to get back to the maintenance shell so I can type code again? And, what code do I have to write in order to restore my computer? Thank you for your attention.

  - by Mixhael

  This started to happen immediately after I had rebooted the first time after doing a system upgrade to 12.04 from 11.10. It first starts with a dialogue that says "System program problem detected". Then when I try to hit 'report problem' not much happens. I am led through a dialogue that always ends up the problem cannot be solved. I am running a MacBook1,1 I am aware this is not a lot of information, however I'm not sure which information I need to publish and how should I obtain it to debug this problem. Here's a screenshot!

• Youtube showing horizontal lines when full screen in google chrome

  - by Blaze Tama

  First, im new in ubuntu so please bear with me. My google chrome shows strange behavior when playing youtube videos in full screen mode. There will be some horizontal white lines, which is exactly like when you playing the game without the vsync. I've checked firefox and the videos working perfectly in there. I also tried to play videos from my HDD using VLC player and its working fine. It seems the problem is in the google chrome alone. My version of ubuntu is 13.04, my laptop is asus n46vz and i use the latest release of google chrome. I've tried to ask google, but it seems he has no answer. Thanks for your time :D

• Gaming with ATI open-source drivers

  - by user7174

  I have recently bought humble bundle 2 ( http://www.humblebundle.com/ ). Is there a way to run Braid using ATI's open-source drivers? The game always crashes. When do get it to start in windowed mode once i go to the first level it will crash. I am using the lastest version of Braid (ST3C ignored) When I use the proprietary drivers Braid works flawlessly and World of Goo performance is increased. However there is terrible screen tearing with the ATI propritary drivers. So my question is: How do I play Braid if I want to use the proprietary drivers?

• Can't install ATI proprietary drivers in 12.10. Unity is Missing

  - by EApubs

  I have a laptop with ATI Radeon 6770M HD Hybrid graphics card. In Ubuntu 12.04, I installed the fglrx driver through "additional drivers" and it worked. (I can even switch GPUs). But in the new Ubuntu 12.10, after installing, Unity won't load. Only the mouse and the wallpaper. If I initialize the settings sudo aticonfig --initial then after rebooting it gives a warning saying I'm in low graphics mode! How to fix this? PS : Earlier i used software source to install the drivers. But when using the terminal, I got this warning : update-alternatives: warning: forcing reinstallation of alternative /usr/lib/fglrx/ld.so.conf because link group x86_64-linux-gnu_gl_conf is broken Update : Filed a bug report in launchpad : https://bugs.launchpad.net/fglrx/+bug/1068661

• 11.04 64 bit live install cd freezes immediately on boot

  - by wrchis

  I am trying to install 11.04 alpha to a free set of partitions to try it out but neither the regular graphic installer or the alternate installer work. The graphic one freezes when I try to boot the cd (or cd image on usb stick rather) with a distorted static picture of my regular desktop repeated four times. I have an nvidia 240 graphics card if that is any help in diagnosis. I think it is a matter of getting the cd image to use a low rez video mode but I have no idea how to force that. I have used both the iso's from the regular page and the daily page (for several days so far) and they all do the same thing. I have tried both the internal utility and unetbootin to set up the stick with the same results. The alternate installer seems to work up to the point of the software selection step and then throws a 'failed step' error part way through.

• Hibernation is still missing from menu in 13.10 after enabling via polkit. How to enable?

  - by LiveWireBT

  I know that since 12.04, we need to add a policykit rule to enable hibernation (see question How to enable hibernation? and the Official Documentation). I can successfully bring my laptop into hibernation mode with sudo pm-hibernate or sudo s2disk, so the rule is in place and works, but the hibernation entry is still missing in the menu. I can tell from looking through the source of the indicator-session package (but not understanding the whole code) that there is still a hibernation menu entry in the code and it should be displayed when the system is capable of hibernating. Please calm down if you're enraged by this. This is very unlikely to be a conspiracy, but rather a bug/regression on a deeper level, which can happen when you move code around or replace it. Question: What needs to be done in 13.10 to properly tell indicator-session that the system can hibernate? Possible duplicate: Hibernation still not available - No activity, because saucy was in development at that time, so out of scope for AskUbuntu. Related bug report: https://bugs.launchpad.net/ubuntu/+source/indicator-session/+bug/1232814

• Compiz window decorator randomly disappears

  - by adjfac

  I know people have posted this problem before such as http://askubuntu.com/users/authenticate/?s=9b515fe8-5da2-4bb9-ba01-dcea538b9b9c&dnoa.userSuppliedIdentifier=https%3A%2F%2Fwww.google.com%2Faccounts%2Fo8%2Fid&openid.mode=cancel&openid.ns=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0 but i am looking for a more permanent solution right now. It happens to me at least once a day and when that happens, I usually go to compiz, uncheck and check window decorator and it will bring it back. But it's sort annoying and just wonder if there is a permanent fix out yet? I am using gnome (not unity), on a bran-new thinkpad t520.

• HP dv2700 series, Wifi not working in Ubuntu 12.10, Wifi Button always disabled

  - by Chicoscience

  I have a HP dv2745se laptop. I always had Ubuntu with the Native Windows Vista and Wifi worked fine. Suddenly my Ubuntu wouldn't load anymore, I tried fixing it for a week and eventually I formatted its partition and just installed Ubuntu 12.10 This laptop has a Wifi switch that works fine in Vista disabling / enabling the wireless connection. HP Wireless Assistant in Windows say Wireless is on. However, whenever I log in Ubuntu the Wifi button is always orange (disabled) and Wireless never works. I had this problem once when I had Ubuntu 12.04 and I fixed it by verifying in Windows that the Wireless Assistant showed the Wireless LAN in "On" mode. However, the same does not work now. I've seen some possible solutions that involve updating the firmware with apt-get. There comes my 2nd problem, my network adapter card is not working and thus I have no internet at all. Any suggestions? Thanks!

• Opinion : les frameworks Web sont-ils une mauvaise idée ? Partagez-vous l'avis de ce développeur PHP ?

  Opinion : les framework web sont-ils synonymes du mal ? J'ai récemment remarqué que personne n'a pris de recul sur les frameworks dédiés au langage PHP. Ils sont utilisés partout, ils sont devenus critères numéro un dans les recrutements de projets, ils sont l'équivalent d'une mode, etc. Bref, le framework est devenu le crucifix du développeur web. Mais un framework, est-ce vraiment que du bien? Non. En rassemblant une certaine quantité d'information trouvée sur quelques débats à propos de ceux-ci, j'ai décidé d'exprimer mon opinion sur l'utilisation d'un framework. Je trouve qu'un framework peut s'avérer être au sens propre le synonyme du mal. Avons-nous des statistiques sur l'utilisation des framewor...

• How to configure screens in console or create screen configuration profiles?

  - by uncle Lem

  I have two monitors and integrated GPU (Intel® HD Graphics 4600). It works fine for work or movies, but if I launch games in fullscreen mode - I get artifacts, glitches and so on. Temporary disabling second monitor solve this problem, but then I have to enable it back, and set its properties manually (by default, additional screen attaches its left-top corner to main monitor's right-top corner, but I need it to be left-bottom and right-bottom corners). So I need some kind of automatization here. Best option - tool to create and swap between some kind of config profiles. Or, maybe, some console manipulations which I can put into script files would be fine too. (Ubuntu 13.04, if it matters)

• Minecraft: Slow performance OUT of the game

  - by blackn1ght

  I downloaded Minecraft yesterday to see what the fuss is about, brilliant game! When playing in Windowed mode, if I try and do anything else, i.e. use the computer, when the game is paused, the computer is incredibly slow, it takes a minute just to type a short message into empathy. Also, once I quit the game, the computer remains slow for about 5 minutes, until it magically frees up and becomes fast again. Could this be related to the 512mb RAM limitation of Java, and the machine is swapping? Even trying to submit this post is incredibly slow and frustrating, it's taking me a minute just to click in the 'Tag's box. Any ideas?

• upgrade from ubuntu 12.04 to 12.10 failed, now loads "grub rescue"

  - by Greg

  I attempted to upgrade from 12.04 to 12.10 last night. Installation seemed to go fine, and this morning I had a message like "restart now to complete installation". So I restart, get an initial "Loading Operating System ..." message, followed by "error: file not found. Then it kicks into "grub rescue" mode. Previously I have this running as a dual boot (window 7) and I just ran the upgrade to 12.10 via the update manager in ubuntu. Any ideas on what is going on here, or what the error means? I know my way around the command line, but this is above my pay grade. Thanks for any advice.
