  • Unity poor performance after upgrading to 13.10

    - by Juzer Ali
    I upgraded recently from 13.04 to 13.10. I have Dell Inspiron 4GB RAM, Intel Core i3. Login takes a lot of time and all the graphics are very slow. Alt + Tab takes a lot of time (seconds). After reading some threads, I also removed Cinnamon desktop, but it didn't change anything. I had to ultimately fall back to Gnome Flashback (no effects). Gnome flashback works fine without any issues. Can anyone please help me get back to Unity, else I will have a very hard time running using Gnome.

  • Cisco Linksys AE2500 wireless adapter not working

    - by makuto
    I have a Cisco AE2500 I've used with my laptop to get internet. I had to install the drivers by following this forum: http://ubuntuforums.org/showthread.php?t=1805830 But now the blue light on the adapter doesn't turn on at all, but ndiswrapper reports it is connected. I have no connection to the internet on my laptop, and the adapter doesn't show it's blue light on any of the USB ports of my computer or on the 4 port hub I have. Is there some way I can reset something so that the blue light will show again? I'm using Ubuntu 11.10 on a Dell Latitude D505 laptop. EDIT: I deleted and reinstalled the same exact driver and everything worked again.

    - by trptplyr
    I wasn't allowed to update to the next release of Edubuntu recently. It gave me an error stating that I did not have enough space to run the update. How can I expand the size of the Edubuntu partition to allow me to update? I am new to Linux so I hope that I am giving you enough and correct information on my system. I am using an older Dell Inspiron 9400 laptop. My root.disk file is 16.3Gb and the system.disk file is 256Mb. I would appreciate someone to point me to documentation or give me instructions on how to do this. Thank you.

  • Horible lag on Xubuntu media center setup

    - by William
    I am setting up a media center running Xubuntu 11.10 as a media center. It is using the XFCE desktop enviroment. I have the NVIDIA drivers installed from the Additional Drivers program, and uninstalled all but the esennitial software. The computer is a Dell Dimension 3000. You can view detailed technical specifications here. The graphics card installed is a Geforce 8400 GS. I have installed all updates through Update Manager. What can I do to fix the horrible lag? It makes watching TV impossible.I have uploaded two videos of the lag, here and here. The second one does not have sound because the sound stops playing on some channels that lag a lot. The TV card is a Hauppage 950q USB, and the TV recording program is Kaffiene. Please help me with this, I am trying to do this to show how great Ubuntu is to the rest of the family.

  • 12.04 BCM4312 and aireplay-ng/airodump-ng

    - by Haxornator
    First off, I've read through all of the posts regarding BCM4312 on the forums but haven't been able to get any help. Basically I have a Dell Inspiron 1564 which I've installed 12.04 on and for the most part everything works fine but now that I'm trying to use more in depth utilities such as aireplay and airodump I'm coming across what I believe to be a driver problem thats not allowing compatibility for these programs. Does anyone out there have any suggestions how to resolve this? This is the error I receive: root@Haxornator:~/aircrack/aircrack-ng-1.1# airodump-ng eth2 ioctl(SIOCSIWMODE) failed: Invalid argument ARP linktype is set to 1 (Ethernet) - expected ARPHRD_IEEE80211, ARPHRD_IEEE80211_FULL or ARPHRD_IEEE80211_PRISM instead. Make sure RFMON is enabled: run 'airmon-ng start eth2 <#' Sysfs injection support was not found either.

  • Choppy/unresponsive keyboard and mouse pointer until suspend

    - by Stefan Thyberg
    I had a problem where my mouse and keyboard would be choppy. The mouse pointer would work at "1-2 fps" and the keyboard would keep missing letters as i was typing them. Since both are USB-Devices, i suspected a problem there immediately, so whenever i got this problem, i would suspend the computer and start it again, for the problem to be gone. The problem started appearing when I plugged the mouse and keyboard directly into the computer rather than the USB-Hub in the screen. I'm using a Logitech UltraX Flat and a Razer Lachesis, on a Dell Latitude E6510.

  • How can I upgrade to Lubuntu 14.04.1 withot a PAE kernel?

    - by Richard
    On my Dell Latitude D800 laptop, which has an old Pentium M without PAE support, I was able to successfully install Lubuntu 14.04 from the CD. When I try to upgrade, I get the error: PAE not enabled Your system uses a CPU that does not have PAE enabled. Ubuntu only supports non-PAE systems up to Ubuntu 12.04. To upgrade to a later version of Ubuntu, you must enable PAE (if this is possible) see: http://help.ubuntu.com/community/EnablingPAE I have seen the Communit Wiki page for PAE. The suggestion is to add forcepae to the command line options. When I do this, I get the same message. Moreover, dmesg does not indicate PAE was ever enabled. Is there anything else I can ry to get Lubuntu to upgrade correctly?

  • No lock screen when the right click menu is open

    - by Shivram
    I just found that the lock screen on my laptop does not show up when the right click menu is open. I discovered this when I pressed the right click button accidentally while closing the lid and the laptop went to sleep, but the lock screen never showed up when I opened the lid again. I am also not able to lock the system manually(with ctrl+alt+L) when the right click menu is open. Is this by design or is it a bug? I would assume that the screen should be locked automatically when the computer goes to sleep, but this doesn't seem to be the case. Anyone have any suggestions? My specs are: Dell Vostro 1500, Ubuntu 12.10

    - by Gorog Imre
    I have a Dell 5720 laptop with ubuntu 11.10. I can't connect to my Samsung LCD TV (over Marantz nr 1601 AV). Audio is ok but the pictures are displayed in two colours: green and lila ! Please send me a massage how can I fix this problem ! Thanks a lot. I am very confused because I do not do anything however it comes(seldom) to the right colouring but only for a while(5minutes) and returns to the green-lila picture again when I do something else for example surfing with firefox or starting other programs ! The settings : resolutions of laptopscreenplay and TV are the same and I did not change the colour profile as well . My laptop screen is HD+ truebright (1600x900) and my TV SAmsung 1280x720 I have no idea what to do my HDMI connection to make right with the colours! How can I fix this situation to gain a stable colouring ?

  • Uncontrolled Fan and Crash

    - by RobotbeatsHuman
    I don't have sensors to properly run lm-sensors. The computer will turn on but shortly there after all the fans in it will speed way up. It stays like this for a few minutes and then the computer shuts off. Tried resetting the BIO. Went to try installing a BIOs update but it wont stay on long enough for me to try that or to do a clean install. Could this be the motherboard dying? It's mainly the CPU fan that ends up going max. after a few minutes. I checked the PSU and It's a Dell Inspiron 580. If you need more system specs just le me know.

  • Samba network sharing NTFS drives and root permissions from local drives

    - by Bill
    I'm able to share my internal 2ndry NTFS drives (sdb1,2 and 3) on the network with Windows computers now but even though Samba read/write is enabled, Windows network computers can only open files "read-only" and can't save files to the samba shared drives/folders. I try to set permissions in Ubuntu via folder and/or file properties even logged in root via Nautilus but all the samba shared folders and files are set as owner = root, accessible and does not allow me to change them to read/write, it just resets to root, accessible, in other words, I can't change permissions. I'm running Ubuntu 11.04 Gnome on an old Dell Dimension 2400. Also, in order to for me to copy or move any files from the Ubuntu drive to the sdb1,2 or 3 drives, I have to gksu nautilus. This consequently prevents me from copying .ISO files to my "Multisys" thumb drive too.

  • Can't print, CUPS package corrupted and hangs on re-install

    - by Little Bobby Tables
    When I upgraded to Ubuntu 10.4 (Maverick), the upgrade process got stuck on the post-installation of the CUPS package. I had to kill processes and run several forced updates before I could finally get regular updated. Ever since I can't print - The printed file gets messed up and crashes the printer. I also can't re-install CUPS, as each time the installation hangs and I have to kill it before it completes. I tried to find a workaround for this problem, but in vain. Does anyone know how to bypass this? Or at least why can the post-installation hang, and how to re-install a problematic package? Some system specs and other hints: Dell D630 laptop running Ubuntu 10.4, Gnome desktop, standard LAN network, printing to an LPD server. Everything worked fine on 9.10. Also, the printed files themselves are not corrupted. The problem does not seem to be Evince-specific, but common to all printouts.

  • Wifi won't work without ethernet (Ubuntu 12.04)

    - by alok
    I have a strange problem. I am running Ubuntu 12.04 on a Dell Studio 1558 laptop. I'm usually unable to access Wifi (I have a BCM43224 wireless card with the STA proprietary driver installed.) So I have to unplug the ethernet cable from my Wifi router and stick it into my laptop's ethernet port to access the Internet. But when I stick the cable back into the Wifi router and try connecting to Wifi, Wifi inexplicably starts working. How can I get Wifi to work all the time without having to 'jumpstart' it with an ethernet connection?

  • GRUB- error: no such partition grub rescue and Error: No default or UI configuration directive found boot > on pendrive

    - by Ash
    I have dell inspiron, previously I installed Ubuntu 11.10 on my Windows 7 and made it dual boot. But since I want to upgrade my Ubuntu version and change the partition spacing, I deleted 11.10 partition directly and extended my hardrive space (Windows + Ubuntu) at that moment everything was fine. Then I prepared a 12.04 32bit USB and installed it . It was installed but isn't showing dual boot option like 11.10 and my machine directly boot into Windows 7. So instantly i again deleted my 12.04 partition . Now I login into Windows 7 but whenever I put USB ( with 12.04 ) to boot from it, I am facing error of "no such partition grub rescue" even though I try to put lower version(11.04) it showing another error "Error: No default or UI configuration directive found boot " I have reinstall Windows 7 and reformat all partition, still I am facing same error :(

  • manage 2 wireless device

    - by yi.tang.uni
    I erased Windows 7 and installed Ubuntu 12.04 on my Dell Latitude E4200. I an very happy with my choice but with little pity. I cannot use the wireless service in my university as the build-in device works unstable. I bought a USB wireless device, which solve the problem. However, the build-in device keep to sent me message about unable to connect, which waste laptop's cup & battery. The phsical bottom to turn off wireless affect both devices. So the question is: "How can I manually shut down wireless device?" There is another interest comes to my mind: "Does 2 wireless improve the overall internet usage if I run a high-internet-consuming program like BT ?" Thank for your time and energy.

  • Confused with X.ORG version number

    - by caligula
    There is my trouble: I'm trying to install ATI drivers on my Dell Vostro 3350 laptop. On the AMD's site I followed steps to determine which driver should I use. After selecting what hardware I use I got a link to download amd-driver-installer-12-3-x86.x86_64.run and below was a description of that driver that it was compatible with X.Org version from 6.7 to 7.6. And I do not know what version of X.Org my Ubuntu uses. Cause after googling I found that version is 7.6 in Ubuntu 11.10. But after typing: X -version I got the output: X.Org X Server 1.10.4 Release Date: 2011-08-19 X Protocol Version 11, Revision 0 So what is the exact version of X.Org in Ubuntu 11.10 and how should one reliably determine it? Can anyone construe? Thanks.

So I definitely want to get the full resolution the display can give me but dont want everything so small. help?? EDIT: Well yes higher resolution means more pixels. But it shouldnt mean fonts the size of of 7 in MS word, and webpages looking like their at 50%... http://i.imgur.com/Ds76nk8.jpg http://i.imgur.com/9fW8vEt.jpg Im not saying windows is better, but windows did not appear miniature at 1080.

  • Unable to login following permission changes in device manager (11.10 + Gnome)

    - by Symanuk
    (Running Gnome 3 on Ubuntu 11.10) Everything working well (at least a couple of months), until recently when I changed the permissions through the device manager on the sda1 /2/ 3 drives, thinking it would save all the switching I seem to have to do between users in order to see / use files I previously copied across from an external drive. Now when I boot up the Ubuntu splash screen loads indefinitely, and if I go in through the GRUB / recover option, i'm getting a load of negative permission messages back (regardless of using the fsck or remount options) Either way = unusable machine (Laptop Dell Inspiron n5050), and no way through to login. I'm looking for: (1) a way back in so any help greatfully received (answers need to be pretty basic as i'm a novice), and (2) if i'm to learn anything, a decent thread on setting permissions within Ubuntu / Gnome 3. I'm new to both Ubuntu & Linux, so please be gentle!! Cheers
