  • Ubuntu on the Sony Vaio VPCY 21S1E

    - by tiax
    My girlfriend got a new Subnotebook for Christmas (Sony Vayo VPCY21S1E), which comes with an "Intel HD graphics" vga adaptor. When I try to boot the Ubuntu installer from USB, the screen goes blank after a short while, before I even see the Ubuntu logo. However, when I select "nomodeset" in the boot options, I can boot it to the CLI login prompt. When I start X, though, that only works in VESA mode (I've read Intel eventually got rid of Usermode Mode Setting and only offers KMS now, which I've disabled to get it to boot). What can I do to enable a) higher resolution than 1024x768 in VESA b) hardware acceleration for compiz, video playback, etc?

  • Ubuntu CD Boots to Black Screen

    - by Thomas
    I have a new Asus N76 Notebook and just downloaded the lastest ubuntu 12.10 desktop CD (x64). When I boot from the CD, I get to the selection asking to try or install Ubuntu (the text screen not the one with the Ubuntu logo). When I select one of these options, I get only a black screen. I have tried nomodeset, acpi=off but it does not change anything. I also tried booting a CD and an USB stick (same result). I have no idea what to try next. I have installed Ubuntu on several computers yet, never had this problem. Any suggestions? Thanks in advance. Thomas

  • Booting the liveCD/USB in efi mode fails on tablet xe700t1a

    - by F.L.
    My tablet is Samsung Series 7 Slate (xe700t1a-a02fr). It operates an intel sandy bridge architecture. The main issue about this tablet is that it ships with a windows 7 install in (U)EFI mode (GPT partition table, etc.), so I'd like to get an EFI dual boot with Ubuntu. But it seems I can't boot on the liveCD in EFI mode. It starts loading (up to initrd), but I then get a blank (black) screen. I've tried the nomodeset kernel option (as well as removing quiet and splash) with no luck. I have used the 12.04.1 desktop iso (I have read somewhere that it is the only one that can boot in EFI mode). What are the other leads I can follow ? thanks

  • Installing Ubuntu 14.04 on macbook pro EFI

    - by user279771
    Macbook pro: mavericks, 5.2, graphics: nvidia geforce 9600M I followed the guides from here: https://help.ubuntu.com/community/UEFIBooting#Detect_.28U.29EFI_firmware_processor_architecture and http://www.rodsbooks.com/ubuntu-efi/. What I have is the following: /dev/sda apple partitions /boot / (root) swap When installing ubuntu, I did not install the boot loader during installation but did so in a chroot environment after installing grub-efi. I installed grub to /dev/sda1 (efi) which created the grub64.efi file in efi/ubuntu. This allows the refined boot manager to bring up grub and select ubuntu however, the graphics does not work. Even after adding nomodeset and removing quiet/splash from the kernel parameters. Any ideas on what could be wrong? To be clear, if I remove quiet/splash, I can see all the text startup messages being printed out however, the display manager doesn't appear to start (the screen stays black). Oddly enough though, the ubuntu startup sound can be heard.

  • Ubuntu won't install from Live CD

    - by Erik Shank
    Complete noob here. I am trying to install Ubuntu 12.04 from a Live CD. I told the computer to boot from the CD (it does) & it reads the CD & then quits with the Ubuntu dots just freezing. I checked the disk & did the memory test, both OK. I also did the nomodeset in the start-up line. Hit escape when it froze but there were no msgs. Have also tried Ubuntu 12.10 & Dream Studio, same thing. Anyone have any ideas? Thanks! Erik The Pope

  • Can't boot into ubuntu, black screen after grub menu

    - by wim
    Ubuntu is not booting properly for me anymore. The grub menu comes up, and whether I choose a linux recovery mode or the normal one I get a black screen after a few seconds. There is a brief message about vga=791 being deprecated, but I am not able to read it fully because the black screen covers it up almost immediately. I have googled for hours for solutions, and most people seem able to solve similar problems by editing in grub and adding nomodeset into the line starting with linux /boot... but this solution is not working for me, I still don't get any GUI. Sometimes I am able to get the dmesg rolling past, I think it was when I removed quiet splash from that line, but still no GUI - the computer seems to be on and working because it responds to a ctrl-alt-del and reboots. I have tried with 3 different graphics cards (2 nVidia and 1 ATI) and swapping them doesn't seem to change the behaviour at all. What else can I try?

  • Display problem with fresh install of 12.04

    - by Dan
    Just intalled Ubuntu 12.04 from CD and install went with no problems. After rebooting, I get the initial purple screen and then a black screen with mouse pointer and a few stray pixels at the bottom left of screen. Occasionally during the boot process, the purple screen comes back momentarily but then back to the black screen with the mouse pointer. When I finally give up and press the power button, the purple screen returns with the Shut Down box visible as it is shutting down. Any ideas? I have tried adding nomodeset after quiet splash, but no change. Possibly not doing it correctly, since I am somewhat of a newbie to linux. Thanks! Dan

  • Black Screen on boot on a Lenovo IdeaPad Z575

    - by Davis
    So I tried to install Wubi. On boot, when I select Ubuntu it starts then I get a purple screen then black screen. My monitor is like completely off. So then I have to hold down my power button and shut it off. I boot it up then held shift and typed in "nomodeset" after the second to last line, but then when it boot it went into the command prompt thing and just stopped after "checking battery" or something. This is my first time installing any linux distro. I want to install it alongside windows and dual boot it with wubi because that is easy and simple. This is the laptop I have: http://www.newegg.com/Product/Product.aspx?Item=N82E16834246328

  • Graphics on boot split into three sections

    - by a sandwhich
    I just installed 13.04 onto a new laptop because of the ease of install with the uefi bios. When I boot the system though, the screen is split into three sections each about 640x200 at the top of the screen, with the active terminal mirrored across them. Although I can login, startx fails due to something about a file. I have tried booting with vga=711 and normal nomodeset with no success. Booting the live usb I originally installed from results in the same issue. The graphics driver in the xorg.conf.something from what I can make out is set to vesa, but it could be set to some other four character value that is similar to vesa, hard to tell. How can I fix this? One thing to note, the laptop has two dedicated GT 750m's, along with the intel 4000 built into the processor. This is what it looks like, the purple box is what the grub2 menu was in before boot.

  • System will not boot without USB thumb drive inserted

    - by agent154
    I've had this issue before when trying out Linux Mint, but I was unable to get any assistance. I was then lead to believe that it was a problem related to Mint, and not grub. I installed Ubuntu 12.04 tonight on a second partition alongside Windows 7. I installed from a USB stick, and everything went peachy until I rebooted without the stick in my tower. It now says: error: no such device: 20cec6ca-4024-4237-84c3-2dba3c851497 grub rescue > I've verified via ls -l /dev/disk/by-uuid that my drive where Ubuntu is installed matches the UUID that supposedly doesn't exist. The UUID of my thumb drive when inserted happens to be 06B3-9C68. There is no mention of my USB drive's UUID anywhere in /boot/grub/grub.cfg I've also tried to re-install GRUB after booting into my system, removing the stick, and running grub-install /dev/sda. It still happens, and I cannot boot without the USB drive inserted into the computer. And what really gets my goat is that the boot order of my system is CDROMHard DriveUSB. It's not even reaching the USB to try to boot from it, so why does it matter that it's not there? Edit: Also, I ran grub-config without the stick in followed by another grub-install. Still no go.

  • Blank screen after installing nvidia restricted driver

    - by LaMinifalda
    I have a new machine with a MSI N560GTX Ti Twin Frozr II/OC graphic card and MSI PH67A-C43 (B3) main board. If i install the current nvidia restricted driver and reboot the machine on Natty (64-bit), then i only get a black screen after reboot and my system does not respond. I can´t see the login screen. On nvidia web page i saw that the current driver is 270.41.06. Is that driver used as current driver? Btw, i am an ubuntu/linux beginner and therefore not very familiar with ubuntu. What can i do to solve the black screen problem? EDIT: Setting the nomodeset parameter does not solve the problem. After ubuntu start, first i see the ubuntu logo, then strange pixels and at the end the black screen. HELP! EDIT2: Thank you, but setting the "video=vesa:off gfxpayload=text" parameters do no solve the problem too. Same result as in last edit. HELP. I would like to see Unity. This is my grub: GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="video=vesa:off gfxpayload=text nomodeset quiet splash" GRUB_CMDLINE_LINUX=" vga=794" EDIT3: I dont know if it is important. If this edit is unnecessary and helpless I will delete it. There are some log files (Xorg.0.log - Xorg.4.log). I dont know how these log files relate to each other. Please, check the errors listed below.

  • Intel HD graphics on Ubuntu

    - by tiax
    My girlfriend got a new Subnotebook for Christmas (Sony Vayo VPCY21S1E), which comes with an "Intel HD graphics" vga adaptor. When I try to boot the Ubuntu installer from USB, the screen goes blank after a short while, before I even see the Ubuntu logo. However, when I select "nomodeset" in the boot options, I can boot it to the CLI login prompt. When I start X, though, that only works in VESA mode (I've read Intel eventually got rid of Usermode Mode Setting and only offers KMS now, which I've disabled to get it to boot). What can I do to enable a) higher resolution than 1024x768 in VESA b) hardware acceleration for compiz, video playback, etc?

  • Dual Monitor/Xinerama not working; cannot even detect on-board graphic card

    - by Steven H
    I have Kubuntu 12.04 and two identical VGA monitors. One I plugged via DVI-VGA adapter into the DVI port of my discrete AMD Radeon HD 6670, the other into the VGA port of my on-board graphic card (Radeon HD 6410D). After installing Kubuntu I got a black screen, so I booted with nomodeset and installed AMD's catalyst drivers but only the monitor plugged into the discrete graphic card worked. Using lspci I saw that the on-board graphics was not listed. Then I found in the BIOS settings the options "Surround View" and "Onboard Dual Link DVI" both disabled. After enabling both, the on-board graphics card shows up in lspci but in amdcccle, it only shows as [Uknown display]Uknown adapter. When I try to enable xinerama, I get a black screen after rebooting on both monitors. I tried several options and hints from the web but nothing worked so far. I also reinstalled the AMD drivers several times. What should I do?

  • Live CD boot/installation problem, blank screen - 12.04

    - by traubi
    I'm trying to install ubuntu-12.04-desktop-amd64 from my usb stick. When booting from usb I instantly get a blank screen (with a grey box at the left bottom) I checked the live system with my laptop.works well except it also starts of with a black screen and a grey box at the bottom. I figure the Problem is my geforce gtx 570 since older versions of Ubuntu where only able to boot with xforcevesa and nomodeset. Unfortunately I can't change the boot parameters. I tried the alternate version for a text based install, but it has the same problem. If I press Esc in the alternate I get a message box with two buttons but no text. I would be happy for any advice on this matter

  • Purple start screen - no splash screen

    - by Peter
    After installing Ubuntu 11.10 on a new computer everything worked fine for a few weeks and now suddenly when starting up Ubuntu I get a blank purple screen with no "ubuntu" splash and the 5 dots but the system does start up. What has happened to loose the ubuntu splash screen? Also, I've checked in the grub startup and it has "quiet splash" in the linux line. I have an ATI radeon 5450 graphics card which needed nomodeset to be added to the grub line when booting for the first time off the install CD but now this line has disappeared from the grub startup. Can anyone help. Thanks

  • How to Access Boot Options 12.04 Live USB

    - by Ryan Kampmeier
    I'm attempting to install 12.04 on my computer but booting from my USB drive results in a blank screen. This has happened since 10.04 and has always been fixed by putting nomodeset in the boot command, but now I can't access the boot options with F6 for some reason. How can I access the boot options? I booted into the live image on a different computer and it worked fine. I'm sure it's because of my Nvidia graphics. When I boot into the live image it shows a small gray box in the lower left corner of the screen and that's it. I can't edit the boot options or do anything else. Thanks in advance.

  • Ubuntu boots to black screen after failed upgrade from 12.04 to 12.10

    This happened when I tried to upgrade from 12.04 to 12.10. I don't know whether the upgrade process had completed downloading and installing packages or whether it was still in progress, but I got a message The application Compiz has closed unexpectedly. At that point, my mouse stopped working so I switched to tty1 by Ctrl+Alt+F1 and rebooted from there. I then found that I could not boot into Ubuntu any more. My screen stayed first purple then black. I went back to tty1 and it said I was running 12.10. I tried some suggestions in this thread on Ubuntuforums: Wubi blank purple screen than blank black screen and this one: How to set NOMODESET and other kernel boot options in grub2 but nothing seemed to work. I can boot Windows as normal. I am using Wubi on Windows7. My laptop is a Lenovo T410i with NVIDA NVS 3100m

  • Unable to install 12.10 on asus r500v

    - by bmdr38
    I have been unable to get beyond the grub boot screen of the live dvd/usb. The Try Ubuntu without installing, Install Ubuntu, etc menu shows, and I have tried adding/replacing nomodeset and no splash with neither helping. Even "Check disc for defects" does not display anything when selected. I am at a complete loss as to how to fix this one. I have had many successful installs in the past, but this is definitely a first for me. Just as FYI, Gfx card: Geforce GT 635M I realize this particular card has Optimus on it, however even the alternative boot/command line install fails to load. Any help would be appreciated. I realize there have been multiple threads on this, but none of the methods within them have solved this yet. Thanks

  • Installing Ubuntu Server 11.04

    - by Jackson Walters
    Trying to install Ubuntu Server 11.04 on an 64-bit AMD machine. The install goes fine until after "Loading additional components", then I get a blank purple screen with a responsive cursor at the bottom. I've looked everywhere and can't find anything (all the documentation seems to be on the desktop version). I have a wireless card installed if that makes a difference, don't why it would. This happens regardless of whether nomodeset is set. Here's what it looks like (as described): Specs: CPU - 64-bit AMD Sempron 140 @ 2.7Ghz RAM - 1Gb DDR3 1333 HDD - WD 500Gb 7200RPM SATA 3.0Gb/s Mobo - Foxconn M61PMP-K Wireless Card - Rosewill RNX-G300LX

  • Ubuntu 12.10 live-usb won't boot

    - by user109175
    I own an Aleutia "Tango" low power PC. It uses a Intel Atom CPU N2800 @1.86GHz processor. I know there are Linux issues with the "Cedar Trail" graphics on this hardware but I can happily run Ubuntu 12.04 using the VESA graphics driver. I wanted to try out Ubuntu 12.10 so I created a live USB under 12.04 but I am unable to get this to boot. It gets as far as the Grub screen but after that the monitor shuts down. I have tried the F6 "nomodeset" option but that doesn't make any difference. Does anyone have any knowledge of this problem? Thanks in advance.

  • Ubuntu 14.04 liveusb boot screen graphic errors

    - by user568109
    I am trying to install Ubuntu 14.04 on my Lenovo Y500 laptop. It came preinstalled with Windows 8. I want to install it in a separate partition with a USB drive. I have tried both Unetbootin and universal usb installer. But for some reason the screen after booting is crappy. The screen goes blank after selecting try ubuntu or install. If I try with nomodeset option the screen only displays on a small strip on the top. Which again is split into three. Each seem to be identical. It is not decent enough to begin installation. The graphic card in my laptop is Nvidia GT650M, if it helps. Maybe the problem is related to that. Can anyone help in fixing this error when installing Ubuntu.

  • Ubuntu 12.10 Help! Everything is incredibly slow

    - by Keith
    I installed 12.10 from usb onto this machine. Intel celeron 2.00 GHz 496MB RAM I had to modify GNU-Grub to read "nomodeset" or i could not see the GUI. I have an Nvidia graphics card. Takes about 2 minutes to boot. The icons on the left of desktop take about 1 min to slowly open their menu. Have a network connection but mozilla is 404 and i cannot update. Where can i find a blow by blow explanation for troubleshooting and repairing this problem?

  • How can I get a 1920x1080 resolution?

    - by Sam T.
    I a newbie Linux and have just installed Ubuntu in a dual boot with Windows 7. I love the interface of Ubuntu but unfortunately I can only get a 800x600 or 1024x728 resolution with black bars all around the screen. I have an nVidia GTX 570 graphics card and an Asus 1080p 23" monitor. What may be of note is that I had to use the nomodeset command on installation of the boot would get stuck at a line with "nouveau", which I understand is to do with the drivers. Additionally, when I type in xrandr to the terminal, it comes up with the error message "failed to get size of gamma for output default". I guess what I am looking for here is someone who could explain to me really simply the steps I have to take to get a full 1080p resolution, at which point I am sure i will become a great fan of the OS! Thanks in advance, Sam T.
