    Red face Blank screen and cannot switch to text console

    Hi all.
    I have problem.

    I installed Ubuntu 8.04 hardy heron from alternate cd. Everything was ok.
    But after first reboot after installation it stopped on blank screen.

    Step-by-step:
    1. power on;
    2. grub, selecting "Ubuntu 8.04, kernel 2.6.24-16-generic";
    3. system is starting, ubuntu logo with loading progress bar;
    4. when progress bar is about 99% complete, screen blink;
    5. for about 2-3 seconds blinking "_";
    6. black blank screen;

    7. cannot switch to text console with ctrl+alt+f1
    7a. i guess i have switched to text console because even i'm not seeing anything i log in like blind and when i press ctrl+alt+del, after some time ubuntu shutting down progress bar appears and it's going to 0%

    I'm using ubuntu since 5.04 and i have the same problem on 7.10 but i haven't solved it and i was still using 7.04 :/

    My hardware:
    Toshiba satellite 1800-554 laptop:
    -celeron 1 ghz;
    -2x 256 sdram;
    -vga compatible controller: Trident Microsystems CyberBlade/i1 (rev 5d)
    -lcd 14.1

    Thanks.

    it seem that your X window failed to startup. I think you can try to use resuce mode in installation CD to enter system for changing X disaplay adapter to vesa? (in /etc/X11/xorg.conf)

    I'm not sure of which part of xorg.conf you are talking about. This is my xorg.conf:

    Code:
    Section "InputDevice"
    	Identifier	"Generic Keyboard"
    	Driver		"kbd"
    	Option		"XkbRules"	"xorg"
    	Option		"XkbModel"	"pc105"
    	Option		"XkbLayout"	"pl"
    	Option		"XkbOptions"	"lv3:ralt_switch"
    EndSection
    
    Section "InputDevice"
    	Identifier	"Configured Mouse"
    	Driver		"mouse"
    	Option		"CorePointer"
    EndSection
    
    Section "InputDevice"
    	Identifier	"Synaptics Touchpad"
    	Driver		"synaptics"
    	Option		"SendCoreEvents"	"true"
    	Option		"Device"		"/dev/psaux"
    	Option		"Protocol"		"auto-dev"
    	Option		"HorizEdgeScroll"	"0"
    EndSection
    
    Section "Device"
    	Identifier	"Configured Video Device"
    EndSection
    
    Section "Monitor"
    	Identifier	"Configured Monitor"
    EndSection
    
    Section "Screen"
    	Identifier	"Default Screen"
    	Monitor		"Configured Monitor"
    	Device		"Configured Video Device"
    EndSection
    
    Section "ServerLayout"
    	Identifier	"Default Layout"
    	Screen		"Default Screen"
    	InputDevice	"Synaptics Touchpad"
    EndSection

    Re: Blank screen and cannot switch to text console

    Hi,

    I manage to access the console chosing "safe mode" in the boot menu.

    Then I log as root and edit xorg.conf using vim.

    At end of "Section Screen" I included:
    SubSection "Display"
    Modes "1024x768" "800x600"
    EndSubSection.

    Good luck!

    Thanks but it doesn't help me.

    Now my xorg.conf looks like:

    Code:
    Section "InputDevice"
    	Identifier	"Generic Keyboard"
    	Driver		"kbd"
    	Option		"XkbRules"	"xorg"
    	Option		"XkbModel"	"pc105"
    	Option		"XkbLayout"	"pl"
    	Option		"XkbOptions"	"lv3:ralt_switch"
    EndSection
    
    Section "InputDevice"
    	Identifier	"Configured Mouse"
    	Driver		"mouse"
    	Option		"CorePointer"
    EndSection
    
    Section "InputDevice"
    	Identifier	"Synaptics Touchpad"
    	Driver		"synaptics"
    	Option		"SendCoreEvents"	"true"
    	Option		"Device"		"/dev/psaux"
    	Option		"Protocol"		"auto-dev"
    	Option		"HorizEdgeScroll"	"0"
    EndSection
    
    Section "Device"
    	Identifier	"Configured Video Device"
    EndSection
    
    Section "Monitor"
    	Identifier	"Configured Monitor"
    EndSection
    
    Section "Screen"
    	Identifier	"Default Screen"
    	Monitor		"Configured Monitor"
    	Device		"Configured Video Device"
    	SubSection	"Display"
    		Modes	"1024x768" "800x600"
    	EndSubSection
    EndSection
    
    Section "ServerLayout"
    	Identifier	"Default Layout"
    	Screen		"Default Screen"
    	InputDevice	"Synaptics Touchpad"
    EndSection

    I have the exact same problem. Only this problem occurs at the boot of the live cd. So i cant even install (k)ubuntu.
    Is there for this problem a solution yet?
