• Problem with dual monitor

  - by Gernot

  I have a laptop with a nvidia optimus graka. I'm also useing a 23" external monitor. It never really worked... . After installation (it was a clean installation) the 23" monitor worked as it should, but the LCD from the laptop wasn't at the right resolution. And every time i tried to change this the PC crashed. Today i had a litle bit of time so i decided to solve this problem. I've tried a few things ( e.g. I've installed bumblebee with the nvidia driver and tested it. It's working...) but nothing solved my problem. Instead of getting any closer to the solution, it's gotten even more strange now... . Now, the display setting isn't recognizing a 2nd monitor at all. But I get on the 23" monitor (which is not shown in the display setting) a screen with the same resolution as the one on the laptop. The display settings looks so: Any help would be wonderful.

• Now that Apple's intending to deprecate Java on OS X, what language should I focus on?

  - by Smalltown2000

  After getting shot down on SO, I'll try this here: I'm sure you'll all know of Apple's recent announcement to deprecate Java on OS X (such as discussed here). I've recently come back to programming in the last year or so since I originally learnt on ye olde BASIC many years ago. I have a Mac at home and a PC at work and whilst I have got Windows and Ubuntu installed on my Mac as VMs, I chose to focus my "relearning" on VB first (as it was closest to BASIC) and then rapidly moved to Java as it was cross platform (with minimal effort) and so it was easiest to work on code from both OSes. So my question, if the winds of change on Mac are blowing away from Java and in this post-Sun era, what would be the best language to focus my new efforts on? Please note, this isn't a general "which language is better?" thread and or an opportunity for the associated flame-war. There's plenty of those and it's not the point. I realise that in the long term one shouldn't be allegiant to an individual language so, taking this as an excuse, the question is specifically which is going to be the most quick to be productive on given the background whilst bearing in mind minimum portability rewrites (aspiration rather then requirement) and with a long term value of usage. To that I see the main options as: C# - Closest in "style" to Java but M$ dependent (unless you consider Mono of course) C++ - Hugely complex but if even slightly conquered, then a win? Is it worth the climb up the learning curve? VB.Net - Already have background so easiest to go back to but who uses VB for .Net these days? Surely if using a CLI language I should use C#... Python - Cross-platform but what about UI for the end-user? EDIT: As a usage priority, I envision desktop application programming. Though the ability to branch in the future is always desirable. I guess graphics are the next direction once basics are in place.

• Problem installing qtbase

  - by teucer

  I am getting the following error when installing "qtbase" package for R: [ 68%] Building CXX object smoke/qt/CMakeFiles/smokeqt.dir/x_1.cpp.o /home/mroot/qtbase/kdebindings-build/smoke/qt/x_1.cpp: In static member function ‘static void __smokeqt::x_QAbstractPrintDialog::x_8(Smoke::StackItem*)’: /home/mroot/qtbase/kdebindings-build/smoke/qt/x_1.cpp:4893: error: cannot allocate an object of abstract type ‘__smokeqt::x_QAbstractPrintDialog’ /home/mroot/qtbase/kdebindings-build/smoke/qt/x_1.cpp:4834: note: because the following virtual functions are pure within ‘__smokeqt::x_QAbstractPrintDialog’: /usr/include/qt4/QtGui/qabstractprintdialog.h:89: note: virtual int QAbstractPrintDialog::exec() /home/mroot/qtbase/kdebindings-build/smoke/qt/x_1.cpp: In constructor ‘__smokeqt::x_QAbstractPrintDialog::x_QAbstractPrintDialog()’: /home/mroot/qtbase/kdebindings-build/smoke/qt/x_1.cpp:4896: error: no matching function for call to ‘QAbstractPrintDialog::QAbstractPrintDialog()’ /usr/include/qt4/QtGui/qabstractprintdialog.h:116: note: candidates are: QAbstractPrintDialog::QAbstractPrintDialog(const QAbstractPrintDialog&) /usr/include/qt4/QtGui/qabstractprintdialog.h:113: note: QAbstractPrintDialog::QAbstractPrintDialog(QAbstractPrintDialogPrivate&, QPrinter*, QWidget*) /usr/include/qt4/QtGui/qabstractprintdialog.h:86: note: QAbstractPrintDialog::QAbstractPrintDialog(QPrinter*, QWidget*) make[3]: *** [smoke/qt/CMakeFiles/smokeqt.dir/x_1.cpp.o] Error 1 make[3]: Leaving directory `/home/mroot/qtbase/kdebindings-build' make[2]: *** [smoke/qt/CMakeFiles/smokeqt.dir/all] Error 2 make[2]: Leaving directory `/home/mroot/qtbase/kdebindings-build' make[1]: *** [all] Error 2 make[1]: Leaving directory `/home/mroot/qtbase/kdebindings-build' make: *** [all] Error 2 ERROR: compilation failed for package ‘qtbase’ * removing ‘/home/mroot/R/i686-pc-linux-gnu-library/2.12/qtbase’ Any ideas?

• Ubuntu 11.10 very slow compared to Windows

  - by Patrick

  I'm new to Ubuntu/linux. Since my PC is very old and not very fast with Windows 7, I decided to give Ubuntu a try, so I downloaded and installed Ubuntu 11.10 today. When I first started it, I had bad 800x600 resolution and it was very slow and annoying. So I installed a driver for my graphic card and now everything looks very nice (1280x1024).But I think it's still far slower than Windows 7. I tried to run in Ubuntu like a few people suggested on the forum but if I log in I get a black screen saying something like "this video mode cannot be displayed". I get that same screen when booting Ubuntu btw, but after about 15 seconds it disappears and just starts Ubuntu. I also installed other drivers for my graphic card but everything stayed the same. I noticed that i.e. when I open Firefox or system settings it takes about 5 seconds till it opens (while Windows 7 takes under 1 second to start i.e. Chrome) and when I do this my CPU usage gets to 100% for a short time. Computer specs: Memory: 2GB RAM Processor: Intel Pentium 4 2.8GHz Graphics Card: Nvidia GeForce 6800 400MHz. I read on various forums that 11.04 works flawless on many PCs, where 11.10 is very slow. Should I install 11.04 or could anybody help me with this problem?

• Acer aspire v3 771G ubuntu 13.04

  - by Jos

  Gooday, i have this acer and i have alot of boot problems (i suspect windows 8) and now i want to try ubuntu but when i use an usb to "try" ubuntu after the boot i get a black screen. now ive read some of the forums and i found something about NOMODESET i have not tried this as i dont know what this does exactly. now i have found this wiki entry https://wiki.ubuntu.com/Bumblebee , i am by far no programmer and always reading all those commands have always kept me of linux because im scared i will !@#$ things up. is there anyway i can go to NOMODESET in the ubuntu "trial" and can i also include the bumblebee futures (coding?) and in how many ways wil this affect my laptops perfomance? reading the bumblebee entry its seems to be something about nvidia optimus and i dont reallt care much for the power saving, but will it affect any performance? im not a heavy pc gamer but i like tho do some gaming and streaming and such also on a rather big TV in wich this laptop already has it flaws in some games not running properly on 65" if this doesn't work or u advise me not to do this what else can i do to fix windows 8 or either some other linux version? i thankyou in advance

• need a different backup solution

  - by DigitalJedi

  I just built a new media/backup server using Ubuntu 12.04 64bit. I installed a hard drive to be used only for music, pictures, and videos and formatted it fat32 so my 1 and only Windows PC could map those folders as netshares. My laptop, also running Ubuntu 12.04, is what I am using the most so new media is first downloaded on my laptop. I've already got the music, videos, and pictures folders from my server mounting as shares on my laptop on boot thanks to some fstab edits and sshfs. Now I'm wanting either an app or script that could backup any new files I add to my local media folders to the mounted folders on my server. I've been Googling all day and found a few apps like rsync but they seem to have issues with ext4 to vfat backups. I thought maybe a script would be best but I'm new to scripting in Linux and don't want to mess anything up. Basically I am looking for something that will backup only newly added files to the server. I figure I could schedule it once a week. There are some stipulations. For example, my local music folder has over 700 folders for each artist/band then sub folders inside those for albums. I want something smart enough to only copy newly added content so I'm guessing the modified date would probably be a good condition if I were scripting. I'm rambling. Any suggestions would be GREATLY appreciated. I'm not finding anything to suit my needs. I'm almost to the point of just learning bas scripting so I can write something but then it will be a couple weeks or so before I have a possible solution and I'd like something in place sooner.

• Lighter in CPU/Memory Usage: Lubuntu or Xubuntu

  - by Luis Alvarado

  I am looking for an Ubuntu version that consumes less Memory and CPU. I have read both Lubuntu and Xubuntu (The homepages, wikipedia, phoronix and other sites comparing both). But from experience, which one uses less memory and is less CPU intensive. I need to install them in very old hardware and want to persuade the owner of the hardware of the benefits of Ubuntu. in this case I want to install 11.10 or 12.04 when it comes out. How are each behaving in those versions? The 2 PCs I will be installing either Xubuntu or Lubuntu are: Granpa PC: CPU - Pentium 2 450Mhz RAM - 64MB DIMM Video - 16MB Used for - Documents and Internet. No listening to music, no looking at videos. Just using it for document writing. The other old meat: CPU - Pentium 3 550Mhz RAM - 128MB DIMM Video - 16MB Used for - Documents and Internet also but they want.. or maybe they are wishing for it to use it to see movies and listen to music. This one has internet. The other one does not.

• How do I get my Intel HD graphics to work alongside my HD7850, as my second(HDMI out) monitor?

  - by AlexTes

  Title says it all. Further info: Motherboard: http://www.asrock.com/mb/Intel/Z77%20Pro3/ Processor: http://ark.intel.com/products/65520/Intel-Core-i5-3570K-Processor-%286M-Cache-up-to-3_80-GHz%29 So currently my main screen is running on my HD7850. Got drivers from the amd website. I have looked through dozens of questions here. I'm about to try booting Ubuntu from a stick and seeing if the xorg-edgers drivers might help. When booting, all action goes down on the very screen I'm trying to get to work.*EDIT never mind this. Seems to be special boot magic. As the screen only displays whiteline errors once the gui of ubuntu has kicked in and everything graphic is happening through my graphics card again. Connected through HDMI(motherboard)-DVI. So unless having multiple displays is a huge deal the solution hopefully isn't that complicated. I just feel I'm missing something simple. If this really is complicated, I should probably just hook up the display to my graphics card. My CPU is usually the one chilling out though so I'd like to try to get that to work. Also just because I don't want to buy an extra cable and this set up makes me feel warm and fuzzy inside. Tell me what to try or look up, I'll be most appreciative. Thank you! **UPDATE The x-swat ppa installed some intel stuff. Booting with one monitor plugged into the motherboard gives nothing. Doing it with the pc already on gives the purple "Ubuntu" with 5 dots boot/shutdown screen.

• Cannot find GRUB - Ubuntu/Windows 8 dual-boot

  - by ubeatlenine

  Hello Ubuntu community, I find myself in an interesting situation. I have a Dell Inspiron 531 with Windows Vista. Recently my brother decided it would be a good idea to overwrite Vista with the Windows 8 consumer preview. Since we have had this PC for a very long time, we have long since lost the Vista CD, and according to the Windows 8 preview website you cannot recover your previous OS without it. I thought this would be a good opportunity to try out Ubuntu (since we obviously cannot keep the preview as an OS), but it appears that Ubuntu 11.10 Desktop is not compatible with Win8. Ubuntu doesn't run from the LiveUSB I made, instead it freezes on the loading screen and then disintegrates into black and white stripes. I blamed this failure on Ubuntu not being compatible with win8 yet and tried to install Ubuntu from the USB on a partition made from the remaining space on my hard drive - about 100GB. However the installer crashed while loading modules and told me I didn't have enough disk space. Since then, I have not been able to load either Ubuntu or Windows, BIOS is shifted over to the left of my screen, and I always get the same message: error: unknown filesystem grub rescue> typing "ls" at the prompt gives me the following: (hd0) (hd0,msdos7) (hd0,msdos6) (hd0,msdos5) (hd0,msdos2) (hd0,msdos1) does this mean I have multiple partitions running windows on my computer? Is it possible to recover Vista without the disk? Are all of my problems stemming from Ubuntu not being compatible with Win8 preview? (I realize the majority of my questions are about Windows, but seeing as the prompt I get is for grub I thought I would ask here first.) Any insight anyone has on this predicament would be greatly appreciated.

• Attempting to install ubuntu 11.10

  - by Orin

  I installed version 9 sometime ago and since have forgotten the process for partitioning, or the layout is different. I have 5 partitions but only have windows xp installed on the pc in question with that being the one of those 5 partitions which is ntfs 34444 mb its - a 40gig hard-drive. My first question is... is there a way to get a screen shot of the partitioner when I am running the demo session straight from disc... these 5 partitions are fragmenting the other 4ish gig needed to install.. I get an error message which says go back and make sure 1 partition has at least 2.5 gig or so. But I have no idea what I am supposed to set these remaining 4 partitions to in order to proceed.. I have read up on install guides and understand that one must be "/" root and another as swap... but to no avail thus far have the correct combo. A few screen shots will no doubt help you guys answer as I'm baffled as to what specific details to give as each one has various settings on inspection, and I don't really feel like writing it all down manually then posting specs for each one

• Just installed Ubuntu 12.04. When booting, all I get is a black screen with cursor

  - by user66378

  Installation appears to go fine. After rebooting, I get my motherboard loading screens, but when it comes time for Ubuntu to boot, I just get a black screen with a blinking white underscore in the top-left - same as I got when waiting for the install CD to load, except it lasts forever. The only keypress it seems to recognize is ctrl+alt+del, which reboots. Letters don't register, function keys w/ or w/o modifiers do nothing. I've installed Ubuntu 12.04 twice and got the same error. The first time, I installed it as the only OS, and had it take up the whole disk. The second time, I installed Windows 7 first, then Ubuntu by specifying custom partitions. After this install, it would boot straight to Windows without showing grub. I used EasyBCD to add the Ubuntu installation to grub, and this got grub to show, and let me select it, but it led back to the same error described up top. I've had Linux Mint 11 and 12 installed on this PC, but was unable to get previous versions of Ubuntu to install (always had errors while installing, not after). Hardware: Intel Core i7-2600K Sandy Bridge 3.4GHz (3.8GHz Turbo Boost) LGA 1155 ASUS SABERTOOTH P67 (REV 3.0) LGA 1155 Intel P67 SATA 6Gb/s USB 3.0 ATX Intel Motherboard EVGA 01G-P3-1371-TR GeForce GTX 460 (Fermi) CORSAIR Vengeance 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Western Digital RE4 WD5003ABYX 500GB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive

• Configuring network to set wlan0 as primary

  - by Sheed

  I recently had to rebuild my pc and decided to go for ubuntu 14.04. I think the mistake I made was I started from a 12.04 install disk instead of the 12.10 disk I'd used previously and when given the option set my primary connection as ethernet (because the wireless option didn't work). After upgrading to 14.04 etc, I managed to get the wireless working, or more using steps like ifconfig -a and the likes I managed to prove that the wireless card etc. is all installed and working. However every time I boot without a hard wired connection plugged in I get the message "waiting for network configuration". I can then once it's booted without a network get my wirless working using sudo ifconfig wlan0 up iwlist wlan0 scan This seems to kick the wireless module into life and it appears in the GUI and I can then select a network, however all the options like edit network and disconnect etc are all greyed out. What I would like of course is if the WLAN0 was just set as my primary default network so I've been looking for a solution to this and it would seem that I need to adjust the old /etc/network/interfaces file but when I try to do so using the sudo vi /etc/network/interfaces command I, well I simply have no idea what I'm doing. Other than that typing :q! gets me out of there before I do to much damage! As far as I can tell (by navigating to the file in the GUI) the output of my /etc/network/interfaces is as follows: (obviously not including the " in each line that's just to break the heading rule of the #) "# This file describes the network interfaces available on your system "# and how to activate them. For more information, see interfaces(5). "# The loopback network interface auto lo iface lo inet loopback "# The primary network interface auto eth0 iface eth0 inet dhcp If this is the case then this clearly doesn't contain what it should do but I don't how to fix it. Nor do I even know if I'm on the right track. Any help would be appreciated thanks :)

• Random greyed unresponsive screen on netbook

  - by user643722

  I love my Asus Eee PC 1000 Ubuntu 12.04 netbook, but I have a little problem. As I use it, the screen will randomly turn grey and become unresponsive. I can then only wait, until perhaps 10-60 secs. later, when I can interact again. Only the bar at the top of my screen retains its colour throughout. I thought it might be Firefox, as I have a lot of tabs open. I installed Chromium, used it instead, and the problem remained. A while back I upgraded from 1 to 2 Gb RAM. So, I thought recently, maybe I should increase the swap-space. I have 738Mb of 7.2Gb free on root; and 2Gb of 28Gb free on my home drive. I bought a 32 Gb SD Card and assigned 4Gb to swap space. cat /proc/swaps reports that the partition is being used. Alas the problem remains. Does anyone know what's wrong with my machine? The SD Card has changed my machine somewhat, but the greying still happens. I ran free -m shortly after another episode, and received: total used free shared buffers cached Mem: 2004 1731 272 0 370 769 -/+ buffers/cache: 591 1412 Swap: 4073 0 4073 Update: Using 'top', I can see that compiz uses about 43% of the CPU (#1 position) when the greying occurs. After the greying, compiz drops back down to its usual 8% of CPU.

• Extended display - nightmare

  - by user206343

  I have been struggling for quite a while, and I hope one of you can shed some lights on my issue. I am using Xubuntu 13.10 (Ubuntu 12.04LTS behaves the same way, higher version wouldn't install, LinuxMint didn't install, Fedora didn't install). I am trying to set extend display for two dell monitors 1900x1200. It works great when in mirror mode, but I just cannot extend the display. Either one monitor goes to sleep and the other is unresponsive, or both work but are unusable. This is a link to the picture of my monitors in mirror mode This is link showing what happens after I try to extend the desktop I get the same results if I use aRandr or the built in configuration utility. I have an ATI Radeon X300 card. I cannot use proprietary Catalyst drivers (I would have to use the legacy ones, which would force me into using much older version of the OS). Extension is possible with Windows. I am hoping someone can come up with tweaks that would allow me to run an extended desktop. I truly love Xubuntu (and Ubuntu, unfortunately, Unity is a bit too heavy for my old PC, and I have to run in 2D mode, so 12.04 is as high as I can go). I have tried everything I could find online, but nothing worked thus far. I believe some configuration or something I am missing might work. Please, if you have any idea, do not hesitate. Thanks guys.

• How to Boot or "enter" into ubnutu 11.04 (Natty Narwhall) on PS3 after installing it?

  - by Xdm

  After failing to install ubuntu 11.04 Desktop version (burned on a dvd, because iso's file size was 726 Mb), in tried the alternate version (about 686 Mb) which i burned into a CD. During the installation process, i manually partitioned the hard drive using ext3. After the installation, the CD ejects itself and i hit "continue". In the k boot prompt i hit "enter" on my the keyboard. I see i welcome message in a dark background (a kind of full screen terminal/console called CLI i think) and was asked to enter my user name and password. After that, instead of booting into the beautiful desktop of Ubuntu, i saw this: ubuntu@my_name$ It was like a line of command i think, where you can use "sudo" commands. It is called a non-graphic mode i think. My my REAL problem is to enter Ubuntu 11.04 with the chocolate-colored background and the African music drum. I tried many commands to boot into the graphic mode of the system such as Ctr+Alt+F7 but nothing happened. In this case, i just saw numbers showing available blocks. I DON'T UNDERSTAND. I also tried startx and sudo startx without result. I DO bought a PS3 BOTH for gaming and for Ubuntu because i can't afford buying a PC. Please help me with my trouble dear Ubuntu 11.04 users. I am counting on you. All the best Xdm

• "drm:[drm_crtc_helper_set_config] *ERROR* failed to set mode on [CRTC6]" during install

  - by Warez J. Coxtrong

  I have a desktop PC which I built a while back. It has an Athlon XP 2500+, 2.5GB RAM, and an Nvidia (PNY Verto) Geforce 6200. I removed the CD drive to add another hard drive so I install from a USB flash drive. When I try to install 12.04 it seems to work just fine. The GUI boots up and wifi even connects to my router. I go through the language screen, the partition screen, the keyboard screen, the location screen, and the import my Windows settings screen just fine. But as soon as I'm done with all that the next screen goes black and displays this message: drm:[drm_crtc_helper_set_config] *ERROR* failed to set mode on [CRTC6] Since the GUI starts just fine earlier during the install, I know I shouldn't be having any display problems, but I am. How do I get Ubuntu to install properly? I have four IDE hard drives, all Western Digital: a 250GB, a 160GB, a 40GB occupied by Windows XP, and a 120GB that I'm trying to use for Ubuntu. 3GB of the 120GB drive are formatted for swap. I have checked the MD5sum of install image file and it all matches up. d791352694374f1c478779f7f4447a3f ubuntu-12.04-desktop-i386.iso

• Upgraded from 11.10 to 12.04 now no network access

  - by MadeTheLeap

  A few weeks ago I decided I should enter the Linux world and read that Ubuntu is the most widely used release. I installed version 11.10 and it worked perfectly. Just this past week I decided I would do the upgrade to 12.04. The upgrade process itself worked fine. However, when I logged in I no longer had a network connection. I am running an AMD-based PC with a D-LINK DFE-530TXS network card and as I said, it worked fine in 11.10. I have scoured the Internet and come across a thousand slightly varying solutions, but they are too convoluted for someone new to Linux. Not because I can't follow the steps, but because most of the tools/utilities that are referenced (e.g. to compile, install, etc.) are not available when I use the stated steps in the solutions. So....should I re-install 11.10 or is there hope in getting this version to use the NIC that I know works. I have the latest driver from d-link for my NIC but I have no idea how to 'install' it for Ubuntu 12.04 to use. I know you will require additional information, but I wasn't sure what you would need. Thanks in advance.

• Weird internet connection issue on Ubuntu 14.04

  - by user287876

  I have an old Gateway PC with Windows 7 installed alongside the original (XP, I think?). A while ago my friend walked me through and helped me install Ubuntu 14.04 alongside the others because my Win7 was having issues with the display driver (it would unexpectedly crash while trying to watch videos on YouTube or other places). And I can't update it because the original computer settings are for XP or something, not Win7. :( We recently switched from AT&T U-Verse to Comcast. I would have stayed with Ethernet, but somehow the adapter I have wouldn't connect to Comcast's thing during their installation. So I was given a wireless USB adapter. It worked fine, up until the last few days. It's not a problem on Win7 (using it right now). Connection's strong, things load. On Ubuntu though, it SAYS it connects even before I login to my account, but when I login and bring up Firefox, it will load the homepage, and maybe one or two other pages I venture to before suddenly just... endlessly trying to load the page. I would normally go in and manually select 'disconnect' from the connections options menu to refresh/restart it like I've done a few times already. But lately, it won't respond, and then a little while later an error message comes up saying the request timed out/failed. Restarting my computer doesn't help it. The other weird thing is that I've noticed the signal (when it's actually working properly before the last few days) is comparitively weaker than when I'm on Win7. But my location doesn't change. It's the same computer, same connection.

• Is it normal for GRUB to take some time (15+s) after I choose what to boot?

  - by zarnaik

  I had been planning to change the background of my bootloader for a while, and finally got to it. Now the black screen I get for quite some time was made clear. It is still GRUB, because the background image stays, while all of the text is gone. Then it just simply shows the Lubuntu loading screen for, usually, not more than 3 seconds. I run Lubuntu 12.10. My question is, is this normal behaviour or is something going wrong, causing GRUB to take longer? Here are the contents of my grub file located at /etc/default/ : # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT=0 #GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX="" GRUB_BACKGROUND="/usr/share/lubuntu/wallpapers/1210-Windmill_by_Ferran_Reyes.png" # Uncomment to enable BadRAM filtering, modify to suit your needs # This works with Linux (no patch required) and with any kernel that obtains # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef" # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE=640x480 # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID=true # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1" If you need any other information please tell me and I'll do my best to provide it. :)

• I bought a new battery and Ubuntu 12.10 isn't recognizing it

  - by user134403

  I inherited my mom's old laptop and installed Ubuntu over top of Vista, so now it is purely Ubuntu. Her old battery only lasted about 10 minutes, so it had to be plugged in all the time, which I didn't like. So I bought a battery, and inserted it in when it came. The laptop doesn't see it at at all- no battery icon whatsoever. I can pull it out and put the old battery in and it recognizes it. The new battery comes with a program (a .exe) to update the bios to accommodate the new battery... But don't have Windows anymore and Wine gives me an error when I try to run it, so I am at a loss of ideas. I thought of running a virtual machine of Windows to install it, or run a Windows To Go drive(a new feature of Windows 8), but I don't think those are good ideas as they may not work or permanently ruin something. I am not an extremely experienced user of Ubuntu/Linux, so I don't where to go from here. I'm running Ubuntu 12.10 on a Sony Vaio VGN-NR, if that helps. Also note that I just installed Ubuntu the other day and have nothing important on the pc yet, so I am not afraid to reinstall Ubuntu if it may help. Thanks!

• Very slow wireless connection (unrelated to power management) using Netgear N150 WNA1100 in 12.04

  - by vgaldikas

  I am using a Netgear N150 WNA1100 USB Adapter. The network driver is: ath9k_htc. When I use Ubuntu 12.04 my wireless connection is much slower than when I use the WNA1100 with my Windows 7 installation on the same machine. I have been researching this and the most common reason for this seems to be related to power management. However for me this is off by default. I had entered a bunch of different commands and, at one stage, I got it to work at full power. But then I rebooted the machine and it went back to slow again. After entering the different commands I was afraid that I may have messed something up, so I performed a fresh install of Ubuntu. I still have the same problem. My wireless connection is still much slower when using Ubuntu than when using Windows 7. I am not sure what other info could help... EDIT: Ok, I have made live usb from the iso file I used to install Ubuntu on this pc, and ran it on my laptop. Still the same problem. However la[top works grand on cable. I suppose this means that my wireless adapter or network driver can be eliminated as root of the problem.. So maybe to do with router itself? I use ZyXEL P-660HW-D1
