• Windows Randomly Stop Accepting Input from Bluetooth Keyboard

  - by dragonmantank

  I've got a laptop running Ubuntu 11.10 with the most recent updates and an Apple Wireless Keyboard that syncs via bluetooth. The Ubuntu box is also a Synergy server, using QuickSynergy to run Synergy. I'm using xmodmap to swap the option and command keys, but nothing else. Throughout the day, windows that are long running will just stop accepting input. For example, I leave gnome-terminal up and running almost 24 hours a day. If it sits for a while, it just stops accepting input. It doesn't matter if I'm ssh'd into another machine or sitting on a local tty session, it just stops accepting input. If I open a new tab or window, those work fine. The 'broken' tabs stay broken. I'm also running Turpial (a Twitter client) which will do that same thing. I tend to use the arrow keys to navigate, and it just stops accepting input. Closing it and reopening it causes it to work fine. I don't seem to have the problem in Chrome, but I tend to open up new tabs when I go somewhere instead of using existing tabs. I've updated all the packages, rebooted, and the only thing that seems to cure it is if I type on the built-in keyboard, the window will start to accept text from the bluetooth keyboard (until it stops again). I don't think the keyboard is disassociating from the laptop because it can happen while I'm using the keyboard, it seems more linked with windows that I sit for a long time. As an example, I'm typing in Chrome with the bluetooth keyboard but I have a terminal window that won't accept input.

• Hybrid Graphics Functional won't work with my Asus UL30V anymore

  - by futuress

  The problem is that I am no longer able to boot in compatibility mode for just turning on my Nvidia graphics to install the driver. Because no login screen will appear if Ubuntu is loading. In Ubuntu 11.10 I was able to activate nvidia graphics only' option this way: 1) Change BIOS to 'compatibility mode' which will turn off the Intel card. 2) Install the Nvidia proprietary driver using Ubuntu's driver finder (Additional Drivers) and then reboot. I was not interested using only the Intel graphics, for the sake of battery life. Now I have both cards running and they drain my battery life dramatically. And the main problem of this configuration no OpenGL is available, so I can't play any games any more. At this point, I have a pre-solution. I uninstalled the nvidia drivers and installed bumblebee. Now the Intel card is recognized. I would prefer to run just the nvidia card as in Ubuntu 11.10 but for now this is better than nothing. Does anybody else have the same problem?

• Ubuntu 12.10: Installing proprietary Nvidia driver causes freeze at boot

  - by Greg

  Ok, so I just installed Ubuntu on my laptop, and I immediately encountered an issue: the HDMI audio output won't work. Yes, I know about the sound settings thing where you have to select the HDMI option, but even when it's selected I get no sound out of the TV I'm hooking it up to. This is a dealbreaker for me, because my laptop speakers are terrible, it's one of the big reasons I use my TV monitor. So I decided to work on solving the problem by upgrading my Nvidia drivers. I switched to one of the propriety drivers offered in that software updating utility that comes with the OS, the one option that said (tested). Viola, sound over the HDMI is now working. Unfortunately, this now brings me to my next problem: when I reboot Ubuntu with this or any other proprietary driver installed, it freezes when it tries to load my desktop. As in I can see my wallpaper, but no icons or options of any kind. The system is totally frozen, and gives me one of those "we've experienced an error, do you want to report it messages." So there's my bind. I need HDMI audio out, that's a total dealbreaker for me, but installing the drivers that give me that capability crash the system. Does anyone have any idea what's causing this

• Ubuntu 12.04 installation on GPT + RAID going into grub rescue

  - by Proy

  I have two 2TB disks. I am installing Ubuntu 12.04 using the alternate version of the server cd. On the partitioning page I have done my partitioning as follows /dev/sda1 - 32 MB - bios_grub /dev/sda2 - 50 GB -raid device /dev/sda3 - 8 GB -raid device /dev/sda4 - Balance full GB - raid device /dev/sdb1 - 32 MB - bios_grub /dev/sdb2 - 50 GB -raid device /dev/sdb3 - 8 GB -raid device /dev/sdb4 - Balance full GB - raid device After this I have setup raid devices /dev/md0 for /(/dev/sda2 + /dev/sdb2) for / ext4 /dev/md1 for swap( /dev/sda3 + /dev/sdb3)for swap /dev/md2 for /home(/dev/sda4 + /dev/sdb4)for /home ext4 The installation finishes it shows that it is installing grub to /dev/sda and /dev/sdb. But once the system reboots it falls into grub rescue mode. on doing ls I can not see the md devices only hd once. I also tried booting into rescue mode with the install cd and doing grub-install /dev/sda and /dev/sdb. What am I doing wrong ? Why is grub2 not detecting the raid revices ? UPDATE: I just did the same steps with Ubuntu 10.04 and it worked perfectly fine. I wiped out the RAID and partitions and everything and did it from scratch. I think the issue is with Ubuntu 12.04 and the way it partitions 2 TB disks

• Intel 5100 AGN disconnects and then disables my Verizon FiOS Actiontec router

  - by Anthony

  I am a new user (my first trial) of Ubuntu and booted up my Windows Vista laptop up with the Ubuntu CD. I was able to connect wirelessly to my router and stay connected for about a minute. After that it would disconnect and my router would be disabled: none of my other wireless devices would see the signal any longer, as if it disappeared. I would have to cycle the router's power toggle off/on to get it to come back on and put out a signal again. This happened repeatedly. I experienced no other problems trying the software (i.e., accessed my files w/o issue). I did not attempt to connect with an Ethernet cable. Here are the specs on my system: laptop is HP Pavilion dv5 Notebook PC system type is 64-bit operating system CPU is Intel Core 2 Duo P8600 2.4GHz ram is 4 GB network card is Intel WiFi Link 5100 AGN I read elsewhere in this forum that 64-bit systems may not be compatible with Ubuntu. Can anyone help me with this? I'd really like to be able to use this op system.

• Problem with APTonCD application

  I created a iso image using aptoncd & burned it to a dvd. Now when i tried to restore, the program does not detect the dvd in the drive.

• dual monitors and unity - ati radeon cards

  - by michiel

  I have a vaio laptop with an ATI Radeon video card and an external screen. I used to run dual monitors on Ubuntu 10.10 fine, but recently decided to upgrade to 11.10 via 11.04 I don't think it's the video card or the fglrx driver. It seems to be unity. When I start up, the laptop screen is normal and the external screen is all white, although I can move my mouse over it. However, the cursor becomes the big X that used to be cursor of the first versions of Xwindows. I can right click on it, and it brings up the context menu for the desktop. And then, all of a sudden, it shows my desktop background. I can continue to move my mouse over the external screen, and now the cursor is normal (little white arrow). But I can't do anything any longer (not even the context menu as before), and trying to drag a window to it (which always worked on 10.10) doesn't work. I actually really like unity. It gives me the most our of my desktop, and uses all space available, which is great. But how can I get my second screen back? I tried unity 2D, but the result is the same. Edit: I think I stumbled on this bug: https://bugs.launchpad.net/ubuntu/+source/nvidia-settings/+bug/882143

• Chromebook C720 - issue suspending and booting

  - by user72727

  I recently bought an Acer C720 chromebook (Celeron, 2GB RAM, 16GB SSD) with the intention of loading Linux and using it as a cheap development laptop while on my holiday. The installation sort of went ok but initially the trackpad didn't work so I ran a script that mostly fixed that. My current issues are: Booting: it still goes to the chrome "unknown os" white screen - I have to press ctrl L - then escape then 1 then wait for 30 secs while it seems to be searching for something. Then Ubunto loads up fine. Any idea how to fix this? Suspend: if I close the lid of the laptop then it doesn't seem to suspend properly. At least when I open the lid the screen appears to be on but the screen is blank with a cursor. Nothing responds on the keyboard and I have to hold the power down to restart it. The suspend from the top menu has the same issue. Moving windows: I don't have a mouse click button so how do I move windows around the screen? Launcher bar: I've set mine to auto hide (which it does) but what exactly do you have to do to get it back? I just repeatedly jab the mouse at the side of the screen and eventually it pops up. I don't mind starting all over again but obviously a quick fix is preferred ;) Mike Ubunto 14.04.1 LTS Kernel 3.13.0-32-generic PS Sorry for so many questions.

• Installing Ubuntu on Asus G75VW (UEFI)

  - by user101653

  You all are my last hope... help! I bought an Asus G75VW from Best Buy. It has the new UEFI BIOS instead of the old style BIOS (1980's) and has Windows 8 preinstalled. I cannot get the G75VW to install Ubuntu 12.10 in EFI mode. I did get Ubuntu to load if I changed the BIOS to CSM and the computer sees and installs Ubuntu in "legacy mode". I attempted boot repair, and Ubuntu will load after 1 minute but as legacy BIOS only. If I changed the BIOS to UEFI "Binary is whitelisted" is displayed and I get a purple screen. My goal... keep my preinstalled Windows 8 on internal drive bay 1 and install Ubuntu 12.10 on internal drive bay 2... and somehow make a choice on which to choose. I am at a loss. I am a software programmer, but I am very bad at understanding BIOS and partitioning. Any ideas? Has anyone done what I want to do. This is a full second day on my "issue"! If I cannot get Ubuntu installed, I'm returning the laptop. And "wait" until these obstacles of UEFI/EFI and properly handled to allow people to load EFI based Ubuntu without a hitch. Thanks, Dave

• Creating floppy drive special devices under Quantal

  - by JCCyC

  First, I'd like for the various special devices for different floppy capacities (like /dev/fd0u720 etc.) to be available. I tried to adapt some udev rules I found online. I tried this, which I saved as /etc/udev/rules.d/70-persistent-floppy.rules: # change floppy device ownership and permissions # default permissions are 640, which prevents group users from having write access # first fix primary devices (/dev/fd0, /dev/fd1, etc.) # also change group ownership from disk to floppy SUBSYSTEM=="block", KERNEL=="fd[0-9]*", GROUP="floppy", MODE="0660" # next recreate secondary devices (/dev/fd0u720, /dev/fd0u1440, etc.) SUBSYSTEM=="block", KERNEL=="fd[0-9]*", ACTION=="add", RUN+="create_floppy_devices -c -t $attr{cmos} -m %M -M 0660 -G floppy $root/%k" But to no avail. It seems the create_floppy_devices script isn't provided with 12.10. How do I obtain it? Second: I'm using MATE, and whenever I log in I get a message box saying it tried to mount the drive but failed. How do I disable this? Third (which is probably related to the second): Whenever there's a disk in the drive, the motor won't stop spinning. If I do a mdir of it, after it returns, the motor stops, and then starts again. I suspect there's some process in MATE doing this. UPDATE: For CentOS 6 (who does have a create_floppy_devices program) the following rules file worked. Saved as /etc/udev/rules.d/98-floppy.rules: # change floppy device ownership and permissions # default permissions are 640, which prevents group users from having write access # first fix primary devices (/dev/fd0, /dev/fd1, etc.) # also change group ownership from disk to floppy KERNEL=="fd[0-9]*", GROUP="floppy", MODE="0660" # next recreate secondary devices (/dev/fd0u720, /dev/fd0u1440, etc.) # drive A: is type 4 (1.44MB) - add other lines for other drives KERNEL=="fd0*", ACTION=="add", RUN+="/lib/udev/create_floppy_devices -c -t 4 -m %M -M 0660 -G floppy $root/%k"

• Resolution stuck in 640x480 in grub, 11.04 and 12.04

  - by user89797

  I have three operating systems on my machine, Windows 7x64, Ubuntu 11.10 and 12.04 both x64 as well. All three were running at full resolution for my monitor, as well as in the Grub 1.99 boot screen. After booting into Windows, I rebooted my machine and found my Grub resolution was suddenly 640x480. Booting into both versions of Ubuntu, I find myself stuck at that resolution as well. I made no driver changes recently, and hadn't even booted into the 11.10 build in a month or more. I've gone through both proprietary Nvidia driver options for my card (GeForce 9800GT) as well as the open source drivers in 12.04 to no avail. I can't figure out what could have caused this change in both versions of Ubuntu and Grub simultaneously. Windows 7 is unaffected so I think that safely rules out hardware failure. EDIT Ok, so I couldn't boot an graphical live disks, I tried ubuntu 12.04 i386 and x64 as well as 12.10 beta x64 and all of them would flash the initial logo, go to a blank screen with a flashing cursor in the upper left and then my display would die. I managed to boot 12.04 server and get into recovery. I reinstalled grub and went into recovery mode for my 12.04 build. If I boot in safe graphics mode I can get 1280x768, but as soon as I reboot it's broken again. I've tried reinstalling the nvidia drivers and that leaves me with a system stuck at max 640x480. None of these changes have had any impact on the 11.10 build, which is still stuck at 640x480 Given that I can push a somewhat higher resolution in 12.04, and full resolution in windows 7 I'm pretty convinced it's not an issue of my monitor failing. It must be something to do with the graphics drivers. I can't figure out what could be the issue though. I'm especially perplexed that I can't boot any live images

• Pasting from vim in terminal to Google Docs (Firefox + Vimperator) - need to understand

  - by LIttle Ancient Forest Kami

  I had some trouble with copy-pasting text from vim in terminal to Google Docs (aka Drive) document (hereafter GDd) in FF browser (with Vimperator). Note: I have a file opened in Vim 7.2 in terminal :version displays both +clipboard and +xterm-clipboard I'm on Ubuntu 10.04 LTS, so I don't think that's Unity-related I want to use Vim, not GVim, nor gedit... I'm avid fan of mouseless navigation, so solution with mouse was not what I wanted. I have the solution, but I need understanding. What I tried and where it gets me: Yanking whole file text via: ggvGy allows me to: paste it via mouse middle button, NOT with Ctrl+v or Shift+Insert here, in text area for entering question text in gedit but NOT in GDd where I want it pasted, even if I switch Vimperator to pass-through mode with Insert does NOT show in XClip after xclip -o From gedit, I can copy-paste the text into GDd (Vimperator's pass-through mode not required). :%! !xclip -i (or :first, last) reports whole file (all lines, to be precise) as filtered, though shell returns 1 `xclip -o' returns nothing (is empty) or returns previously copied value with 2. no surprise, but I can't paste at all not only to GDd but also to gedit or here setting clipboard (:set clipboard=unnamed) to unnamed doesn't help using "+y or "*y on whole file text actually does the trick So, the question (it's actually three, say "split" and I will): why middle mouse button pastes different things than Ctrl+v and how to know what will be pasted with each? why just yanking (without registers) works with mouse but not with keyboard / XClip? why didn't unnamed register help? After setting, it should make unnamed and * registers same?

• Webserver on a rotating server with NAT IP or changing IPs

  - by hpsoftware

  i would have to elaborate my questions so please have patience Explaining the logic. if you are familiar with logmein then it installs a client software on your computer then it kinda keeps tracks where you computer is as long as it's connected to internet. So you can always access your computer no matter where it is whatever it's IP is you just go to logmein.com and then you can just access it. Now what i am asking 1. Let's assume i have a website hosted on my laptop let's call it webserver. so then i move around i have a new IP sometime even on a hotel network is it possible to do something like what logmein does so i can keep moving around my Webserver to new IP but it has some local client or something which keeps updating my IP or something i am sure i would need a gateway server somewhere which is connected to my domain name via DNS so somebody accessing my website www.mywebsite.com goes to my main server then gets routed to my laptop which could be anywhere but my gateway server is able to communicate to my webserver I will keep updating the case description based on comments to make more sense. please have patience with me.

• Battery is drained too quickly

  - by LucaB

  I'm getting really low battery life under ubuntu, not even close to windows. I tried powertop, and I saw that my laptop is consuming in idle nearly 20 watts (a bit more). I tried to install laptop-mode-tools, change "good" into "bad" in powertop, but nothing changes. I see that I have the the HD audio output device which is running at 100% every time. Could this be the problem? This is a report from powertop.

• Windows 7 and Ubuntu Boot/Corruption Problems

  - by Kiraisuki

  I searched around, but I couldn't find the answer to why Windows 7 Ultimate 64x and Ubuntu 12.04 LTS 64x could'nt live together happily on my Asus G1s-X1 laptop. I had Windows 7 Ultimate 64x installed on the laptop when I bought it (bought it used, it comes with Vista new) and I wanted to try out Ubuntu and see what all the hype about the free OS was. I installed Ubuntu on an external 80GB iomega HDD with Windows 7 on my main drive. They both work fine for about 2-3 weeks, until Ubuntu suddenly is unable to boot. A few days after Ubuntu fails, Windows corrupts majorly (winload.exe, ntkrnlpa.exe, and various others corrupt randomly) and Windows Recovery Environment is completely useless. Booting to a live USB with Ubuntu and trying to reinstall it fails, and trying to wipe the main drive and install it there fails as well (something about my graphics card.) I managed to get Windows 7 Ultimate 64x back up and running (after many disk formats) but now I am left with a broken (and invisible) Ubuntu installation on the external drive. Is there any way to get the broken and non-bootable Ubuntu installation off the HDD without damaging or erasing the many files and programs installed and stored on the 80GB drive?

• 11.10 liveCD black screen

  - by Shaun Killingbeck

  Attempting to install/try ubuntu 11.10 on my new laptop, using a liveCD (and tried USB). I get the purple screen (with the man/keyboard at the bottom) and after that the screen flashes bright white before going black. Ubuntu continues to load in the background, with login sound etc but the screen is off. I have tried as many different solutions as I could find including: using nomodestep, xforcevesa, i915.modeset=0 in boot options (seperately): varying consequences, but either I end up at a blinking cursor with no prompt, a command line (startx fails: no screen found), or the original blank screen again Tried booting from VirtualBox - it crashes at the same place the screen would go blank when using a CD/USB tried 11.04: I don't have this problem BUT when trying to install, I get a ubi-partman error 141 (possibly down to the three partitions that came on my laptop... not sure why HP needed there own separate partition for HP Tools...) Model: HP Pavillion DV6 6B08SA Processor: AMD Quad-Core A6-3410MX APU with Radeon HD 6545G2 Dual Graphics (1.6 GHZ 4 MB L2 cache ) Chipset: AMD RS880M Any help would be greatly appreciated. I just want to be able to partition the drive and install Ubuntu. I'm assuming the issue is graphics card related, although I have no confirmation of that. I have caught a glimpse of some output to do with pulseaudio and [fail], but I can't imagine why that would cause a screen problem and the sound definitely works anyway.

• Ubuntu won't suspend anymore, but it did upon install.

  - by Bruce Connor

  I fresh installed Ubuntu 10.10 back when it came out, and my laptop was suspending fine. All of a sudden, I can't get my laptop to suspend anymore. It's an HP Pavilion dv2-1110, but I don't think it's a hardware issue, here's why: It suspended fine upon first install. I haven't installed any new kernels since then, but I have installed tons of packages, so it's probably a package. The suspend and hibernate options disappeared from the shutdown menu. If I press my keyboard's suspend button (or if I close the lid) I get the following message: If I try the command pmi action suspend, I get the error message: Error org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.Hal was not provided by any .service files. If I try the command echo -n mem > sudo /sys/power/state I get absolutely no output and no visible effect. What might be causing this behavior? I thought a list of installed packages might be useful, but it's huge and I don't know how to post it here in collapse/expand mode or something. EDIT:Just in case someone asks, none of the installed packages are kdm or anything like that (which would justify the lack of options in gnome's shutdown menu).

• Precise: Evolution laggy due to IMAP -profile or due to some odd Sync -issue?

  - by Izzy

  I'm fighting with Evolution. Basically it's working fine -- but it is very slow to react in certain situations. There is apparently some problem with syncing and IMAP. Helper questios Could be that changing away from Bonobo has to do with slowing-down? There might be some trouble with the new engine and "asynchronous actions". What to do about it? I want to get the previous "working mood" back. How can I speed this thing up? Different scenarios when sending a mail, the composer window hangs there inactive for a couple of seconds, everything grayed out. Though there is a green check mark saying it's sent, I'm not sure a) why it's still blocking everything and b) whether I could simply close it without "breaking"/"losing" anything. In earlier versions, the composer window was closing pretty fast, and one could see the message being stored into the local "outbox" until it was sent, and one could immediately continue with the next task. I prefer that behaviour over the current. switching between modules. Coming from mail and switching to the address book takes a couple of seconds. Same for switching to the calendar. I read about different "possible causes" and tried a few things: I only have 3 local address books, so no networking should be involved here. To make sure, I switched to offline mode and then tried to access the address book. No noticeable difference. I use 3 Google Calendars. Switching to offline mode made a minor difference, but so minor that it also could be "imagination" since one might have expected this in this case according to some reports, disabling the tasks should help. Well, it didn't in my case, as I don't use them regularly (just two local items stored here)

• Why does Ubuntu 13.10 not detect my Win7 partition?

  I'm trying to install Ubuntu 13.10 alongside Windows 7 on my DELL INSPIRON 14z 5423 laptop and I'm new to all of this. I'm using the Ubuntu 13.10 64-bit ISO burned onto a CD. The first time I tried to install it, Ubuntu said it did not detect any other OS, which meant I only had 4 options: Erase disk and install Ubuntu (I don't want to do this) Encrypt new Ubuntu. Use LVM. Something else. If I choose the Something else option, it brings me to the partition menu and says that I have 1 disk with free space of (500Gb), but that's not true because I have Windows 7. I restarted the laptop several times and booted the CD again and I got exactly the same as I did previously. How do fix this problem and install Ubuntu alongside Windows 7? After executing "sudo fdisk -l" command in terminal ubuntu@ubuntu:~$ sudo fdisk -l WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.

• CUDA & MSI GT60 with Optimus enabled GTX670M?

  - by user1076693

  I have a MSI GT60 Laptop with an Optimus enabled GTX 670M GPU, and I have been trying to get CUDA going in Ubuntu 12.04 environment. I realize that Optimus is not supported in Linux, but I have read the following post suggesting that CUDA works for hybrid GPUs. How can I get nVidia CUDA or OpenCL working on a laptop with nVidia discrete card/Intel Integrated Graphics? I installed the NVIDIA driver via sudo add-apt-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get install nvidia-current The resulting driver version is 302.17, and supposedly GTX 670M is supported since 295.59. I also downloaded CUDA 4.2 from the NVIDIA site, and compiled it against nvidia-current libraries. Unfortunately, when I run deviceQuery in the CUDA SDK, I get the following output cudaGetDeviceCount returned 38 -> no CUDA-capable device is detected Checking /proc/driver/nvidia/gpus/0/information gives the following Model: GeForce GTX 670M IRQ: 16 GPU UUID: GPU-????????-????-????-????-???????????? Video BIOS: ??.??.??.??.?? Bus Type: PCI-E DMA Size: 32 bits DMA Mask: 0xffffffffff Bus Location: 0000:01.00.0 Here is the output of "lspci | grep VGA" 00:02.0 VGA compatible controller: Intel Corporation Ivy Bridge Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation Device 1213 (rev ff) So... what am I doing wrong? Thanks!

• Dell M4600 with nVidia Quadro 2000M hangs on boot when external monitor is connected

  - by vladeta

  I have a problem with my fresh installed Ubuntu 12.04 LTS on my Dell M4600: nVidia quadro 2000M i7-2860 16GB ram 128GB SSD Dell/Samsung 750GB HDD IPS RGB laptop display When it is connected via DP++ to the external Dell U2311H monitor, it hangs on boot or when wakening from suspend. If I detach the DP cable it boots normally. I have tried all combinations that I have found, as adding to grub: "no splash", "boot=pci", "acpi=off", etc... I have also changed in nVidia X settings that external monitor is the primary one and also tried to delete monitor.xml file. There is no change it hangs each time after grub. It starts to load daemons then both screens are blank and then completely hangs with beep sound. What I discovered is if I detach the cable and wait for about 2 sec after grub starts booting and then physically connect DP cable while the Ubuntu is still booting everything works normally and I have a picture on my external screen while the laptop screen is off, just as I wanted. Do you maybe know how to solve this issue? Thank You.

• What Does Installing Ubuntu "Alongside" Windows Entail?

  - by Soft Skeleton

  I recently posted a question about an error I was receiving trying to access Ubuntu from the boot menu. I am using Windows 7 and Ubuntu 12.x (I THINK because I haven't accessed it in over a year due to being unable to run an important program for one of my classes on Ubuntu). On another laptop, I partitioned the hard drive and installed Windows and Ubuntu on the partitions. On this laptop, I simply installed Ubuntu from Windows, picking the option "alongside Windows", and didn't partition my hard drive manually. I was under the impression "alongside" entailed that Ubuntu would partition my hard drive, and that if I were to return my Windows partition to factory settings it would not affect the Ubuntu partition. However, given my current problem, I am wondering if I was mistaken in this assumption? When installing Ubuntu from Windows, selecting "alongside" Windows as the option from the Ubuntu installer, does that simply install Ubuntu within the Windows partition and thus returning it to factory settings would wipe out anything I had on the Ubuntu OS as well? Ubuntu is still in the boot menu as an option, but when I try to access it it says the drive is "corrupt" and wubi is mentioned in the error. I additionally tried to download a program ran from Windows to investigate partitions and there were no sign of my Ubuntu partition viewable from Windows. Is it possible Windows just can't see it? Any insight, corrections or answers is appreciated.

• Colored Vertical Lines upon boot and nomodeset DOES NOT fix it

  - by user2851032

  I have installed Lubuntu 13.04 on a Dell Inspiron 1501 laptop, rebooted the machine and encountered this problem. I edited the GRUB configuration to remove "quite splash" and enter "nomodeset", updated grub, and everything was fine. I could reboot the machine without any trouble. However, if I unplug the machine, wait a few seconds, and plug it back in, the problem with the colored lines comes back and nomodeset no longer helps to solve the problem. I tried using radeon.modeset=0 instead of nomodeset and that also works on multiple reboots until I unplug the machine and plug it back in. I was finally able to get around the problem by entering "radeon.exapixmaps=0" instead of radeon.modeset=0. I suppose I kind of made up that boot option using some information from an Arch Wiki page. This would work throughout reboots and even if I unplugged the laptop. It was working fine for quite a while. A few weeks later, I had some unrelated issues with the Java iced-tea plugin, and since 13.10 had just come out, I thought I would try upgrading. So upgrading didn't fix the problem with Java, and after unplugging the machine and trying to use it later, I was back to this problem with the black screen and colored vertical lines. I am completely out of ideas on what to try. It took me a week to figure out how to get it working the first time, but the solution I had isn't working anymore.

• Restart and/or graphics problem in Ubuntu 12.04

  - by kara

  I having been using 12.04 for a couple of months now, with v. little problems. The other day I restarted my computer, and though I think it rebooted, the screen would be black. I could not even get a visual from a live cd. Finally, I was able to get it to load, but the resolution has been completely off. The computer thinks I have a laptop screen, when I actually have a ViewSonic VP2330wb, and it detects only two resolutions. And still, I have a problem with rebooting. If the screen locks after I leave it for a while, I can't get a visual back, and then when I force a shutdown, it takes 3 times for me to get a grub screen. Then I have to boot in recovery mode, and then finally in normal mode, but the screen is still always off. This is my video card: description: VGA compatible controller product: 2nd Generation Core Processor Family Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 09 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list configuration: latency=0 resources: memory:fe000000-fe3fffff memory:d0000000-dfffffff ioport:f000(size=64) I am a new ubuntu user, and am at my wits end. Any help would be greatly appreciated.
