    10.04 LTS RC: Blank Screen at startup

    Hey, all. I've been using Ubuntu off and on since 6.10, but I am definitely a noob when it comes to troubleshooting this kind of stuff. All of my previous installs went flawlessly, so I guess I've been lucky so far. I finally decided that I would bite the bullet, and remove Windows altogether. No more dual-boot with XP or 7 for me.

    I've been attempting to install the 10.04 RC all weekend, and it's been pretty frustrating. I decided I would start with my aging laptop, a HP Pavilion ze8500 that I custom-ordered way back in 2003. A few specs I know off the top of my head:

    P4 (2.30 GHz)
    512MB RAM
    40GB SATA HDD

    I burned the ISO to CD-R and started the install. When I boot from the CD, I get a purple screen which is blank other than two symbols at the very bottom. IIRC, one looked like a ruler or something, and the other looked sort of like a star in a circle? I think they were separated by an equal sign.

    I have no idea what that meant, but I knew enough to hit F6 and that got the install menu to appear onscreen. The only way I could get through the installer without losing video was to use 'nomodeset'

    I installed over top of Windows 7 RC with the default partition table settings and after the install finished, I got the dialog box telling me that a restart is necessary. I hit Continue, the CD tray ejected, and my laptop restarted.

    So, assuming that the installation was a success, I see the BIOS screen, and then that goes blank, and where I would expect to see a boot screen or a Grub dialog, I see nothing at all.

    After the first install attempt, I would hear a drum sound after the screen went blank.

    I tried hitting 'Esc', along with 'Ctrl+Alt+F1', 'Ctrl + Alt + F2' or whatever else I could think of, and nothing seems to work.

    I updated my BIOS, remembering that I forgot to do that, and then I reinstalled Ubuntu. Again, no display when Ubuntu boots. And now, I hear no drum sound at all.

    I am certain I was using an ATI video driver with Windows, but other than that, I don't know any specs on the display off the top of my head.

    Am I doing something wrong, or does anyone have any suggestions? I'd really love to get this working so I can finally ditch Windows for good on my other two computers.

    Re: 10.04 LTS RC: Blank Screen at startup

    I'm having the same problem.

    My desktop, I just installed 10.04 RC x64 on it. I was using a USB stick to install from. I downloaded the 10.04 RC and put it on the USB stick with UNetBootin, rebooted and told the system to boot from the USB stick. It started to boot, and ended up in a blank screen.

    I thought maybe it was an issue with the image so I decided to download 9.10 x64 and then upgrade to 10.04 RC x64. I installed 9.10 x64, and everything went perfect. Booted in for the first time and beyond not having the resolution set properly it seemed to be working fine. I started the upgrade process and once completed I rebooted the system. I get a black screen and just as the OP mentioned I can hear the welcome jingle, but the screen stays black and goes into power saving mode. Like there is no signal coming from it.

    System specs:

    Intel Q9450 @ 2.66Ghz
    Asus Rampage Extreme
    4GB G-Skill DDR3 2000
    ATI Radeon 5870
    Creative X-Fi

    Any help would be appreciated. I'm interested in switching to Ubuntu as my primary OS, but if this can't be resolved then I will have to stay with Windows 7.

    Re: 10.04 LTS RC: Blank Screen at startup

    Same issue here no video after the ubuntu logo and dots, system below:

    Ubuntu 10.04 RC 32-Bit
    Intel i7 920
    6GB Ram
    Gigabyte GA-X58A-UD7 Motherboard
    ATI HD 5970 2GB

    It made it to the desktop because I was able to click the menu and see the disk access because it was in LIVE mode and I shut it down blind using keystrokes.

    It sucked when I booted back into windows, both my ethernet ports were dead, no power it seemed, reboots didn't help, had to shut down and and unplug my power supply for a minute and boot back up.

    Re: 10.04 LTS RC: Blank Screen at startup

    From searching around it seems it is a problem with ATI cards.

    However, that being said, I am writing this on a laptop with an ATI Xpress200M graphics chip in it and the 10.04 32-bit RC install went flawlessly.

    Maybe something for the dev's to look into before the release in a few days. Newer ATI cards seem to be having problems after fresh install and after upgrades to 10.04.

    I finally figured it out, I switched the connector on the video card that my monitor was attached to, since getting the card I have had my monitor attached to the DVI connector farthest from the motherboard or better yet the one next to the screw on the bracket. I moved it to the other DVI connector booted up like that and I get video and no blank screen anymore.

    I always wondered which one was the primary port because my card was not marked, I have a Sapphire HD 5970.

    Good Luck!!!!!!

    I tried switching connectors. Plugged into first DVI port and rebooted, no luck. Second DVI port, rebooted, no luck. HDMI port (using HDMI to DVI cable), rebooted no luck. DisplayPort (using DP to HDMI adapter), rebooted and no luck.

    I have re-installed Windows 7 and will stick with that till a newer version comes out.

    Re: 10.04 LTS RC: Blank Screen at startup

    Well, I did a dual boot setup on my primary desktop PC last night and it works flawlessly. Perhaps that is because my desktop has an nVidia rather than an ATI...

    I spent all last night messing around with Lucid on my desktop (sleep is overrated.) I love it and I will definitely be installing over Windows 7 with the final release in a few days.

    I'll stick with Karmic on my laptop until the ATI issue is resolved.

    Exactly same issue here - installed no problem on my Nvidia containing laptop. Using a HDMI connection for the visuals.

    My specs are in my signature. Must be an ATI problem. Hopefully they will sort it for the full release later this week!!!
    Laptop : Acer Aspire 5920G Intel Core 2 Duo T7300, 4GB DDR2, NVidia GeForce 8600GT, 500GB HDD
    Desktop : Intel Core i7 930 overclocked to 4GHz, 6GB DDR3, ATI Radeon HD 5870 Vapor-X, 2TB + 2TB + 300GB HDD & 60GB SDD

    Same issue here

    HP Pavilion SLimline s7727c

    with
    VGA compatible controller: nVidia Corporation C51 [GeForce 6150 LE] (rev a2)


    Just a blank screen. I tried various video modes, no luck

    Update:
    I booted from the cd, pressed F6 and then selected the Nomodeset option. The install proceeded without any problems. However I am back with a blank screen with a monitor message that the video mode cannot be displayed. This is true even if I select the recovery option at boot. Now I am stuck.

    Any Ideas??
