somewhat of a workaround:
Hold down left-shift on boot to enter GRUB
hit "e" to edit the kernel
remove "quiet splash" and replace with "nomodeset single"
control-x to boot
(http://bugs.launchpad.net/ubuntu/+so...2/+bugs/511130)
A system recovery screen appears, I selected "start ubuntu normally" (or whatever option is similar) which put me through to a shell login prompt. After logging in to the basic shell I typed:
Code:
$ sudo /etc/init.d/gdm start
Which, much to my surprise, launched the Lucid Lynx gui.
I'm using the standard drivers for my video card (I attempted, but failed to install ATI's catalyst control center.)
^^^^^^^^^^^^^^
Re: 10.04 LTS RC: Blank Screen at startup
For me, I seem to have found the workaround.
First, credit where credit is due:
http://ubuntuforums.org/showthread.php?p=9221567
So, to make this change (remember to ALWAYS preserve a backup of your files)
Code:
$ cd /etc/default
$ sudo gedit grub
The editor will come up
Locate this line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
Change it to:
GRUB_CMDLINE_LINUX_DEFAULT="radeon.modeset=0 quiet splash"
Save, reboot, and voila!
When Lucid is installed, it defaults to KMS - Kernel Mode Setting, which means the Kernel determines the graphics mode to launch in. It seems that ATI cards don't like this and cause the Blank Screen of Death(tm).
Further reading:
https://wiki.ubuntu.com/X/KernelModeSetting
Further note: I make no promises as to whether this change will work on "your" system.

Edit: Did you run

Lucid Lynx and NVIDIA video cards

I’ve installed nvidia-current. Now
lsmod | grep nvidia
shows me that the nvidia module is loaded, everything is ok, except that i can’t turn on the composite and all those visual effects, that worked fine in karmic.The problem solved, now i’m using native NVIDIA 195.36.24 driver. Here is what i’ve done:
http://lushchick.blogspot.com/2010/05/lucid-lynx-and-nvidia-video-cards.html
.........
This really sucks. Unfortunately even the latest driver available in Lucid’s “Hardware Drivers” menu doesn’t support my NVidia GT 240.
Worse yet, the Nouveau driver doesn’t work very well with my card, either, leaving strange artifacts on screen during startup and locking up the X Server every now and then.
If the nvidia drivers don’t allow you to have special effects, just try this :
blacklist nouveau
blacklist lbm-nouveau
..in the following file :
/etc/modprobe.d/blacklist.conf
.. then :
#update-initramfs -u .. in a terminal.
Download and install normally the nvidia proprietary drivers. Restart the X server … and everything should be OK!

On a terminal
(alt+ctrl+F1)login and type:
ps -ef
of
top
cat /etc/X11/xorg.conf
Try to ssh into it when it freezes, if you can. Many times I've had a hard X server lockup, but I can still login remotely and kill X.
To ssh into the machine, you need another machine on the same network (it can be any OS). Install openssh-server, and start it with
Code:
/etc/init.d/ssh start
Code:
ssh antonio@192.168.1.200
Try
Code:
sudo ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key
Code:
sudo /usr/sbin/sshd -t
------------
ssh's port is 22,
Try a
Code:
sudo apt-get --purge remove openssh-server
You could also try installing a telnet server, that might be easier to do, and we can still log in and look at the machine (or if we can't, then we probably can't with ssh either).
Code:
sudo aptitude install telnetd
You don't need telnetd on the remote machine, just "telnet" (the client). Telnet should also be available on a Windows machine, just start the command prompt and run "telnet".
Logging in:
Run telnet
Inside telnet: open 192.168.0.5 (or whatever your IP is)
You should get a login prompt, where you type your username and passwd.
------
An open port means that a) nothing is blocking the port and b) something is listening on that port. If you have no firewall, it should just work; mine started up telnetd automatically when I tried to log in (the "internet daemon" inetd listens on port 23 and starts telnetd). I have tried this from an XP machine.
Is anything else on your machine out of whack? Is all this trouble another manifestation (like the lock ups) of a deeper problem?
--------------------------------------
it sounds like you have enabled desktop effects (wobbly windows and the like) before you removed your video drivers. by doing that you have disabled hardware 3d acceleration which the desktop effects needs to run. instead the desktop effects are just showing a 'white screen'.
im not sure howto disable desktop effects from loading on login so id recommend that you run the command
sudo apt-get remove compiz beryl
after logging into recovery mode
(see: https://wiki.ubuntu.com/RecoveryMode to learn more about howto boot into recovery mode)
if you want the desktop effects back you will have to re-install you restricted video drivers and then install compiz or beryl from synaptic.
----------
got to a terminal and did a
sudo apt-get remove compiz beryl
but it reported a bunch of packages no longer needed that weren't removed automatically, mainly compiz libraries IIRC. Simply running the above command did not fix the system, but running
sudo apt-get autoremove
after removing compiz and beryl did fix it.

sudo dpkg-reconfigure xserver-xorg
and set the following options:
- Kernel framebuffer device NO (in your xorg.conf this option should appear as "false")
- 16 bit (instead of the default 24-bit selection)
Restart X and see if you have any improvement.

Black screen on 10.0
So after a lot of problems upgrading to 10.04, eventually a clean install. First in 8.04, 9.10 and now as said in 10.04 for the second time, problems with the screen. It starts, gets a bit grey, then I see the GNU without touching keys, I choose the one at the top, Get's black again, Then some orange shows very short and I can log in, but not in any interface. Just as root in terminal. That's as far as I get.
The machine:
PC1(wired)10.04; ASRock N68; Dual AMD 64 Athlon(tm) II X2 240; RAM: 2048 DDR2; ATA Disk WD320Gb; Atheros AR5001X + W'less Sitecom 300N ; VGA compatible controller C61 [Nvidia GeForce 7025 / nForce 630a]; screen Acer 19'' V193HQ 1280x720 max.
Tried this:
https://help.ubuntu.com/community/BinaryDriverHowto/Nvidia
Installed this one
http://www.webupd8.org/2010/06/how-to-install-nvidia-25635-display.html
Worked great for 2 weeks and is now gone with the wind. Nowhere to find. Strange.....
This hereunder is what's on it, I can imagine it will conflict, but what can I get rid of and what not. And how, I can only work from USB-Stick.

Section "Screen"
Identifier "Default Screen"
DefaultDepth 24
EndSection
Section "Module"
Load "glx"
EndSection
Section "Device"
Identifier "Default Device"
Driver "nvidia"
Option "NoLogo" "True"
EndSection
Last time I changed the xorg.conf with the failsafe file and it worked again, now it does not.
I now also edited the kernel, removing quite splash with " nomodeset" . Nothing!
Kernel is the newest as well, ends at .24
The story:
Two days ago, in the evening i just normal stopped, and in the morning it didn' t do anything anymore. The recovery mode even does not work. Everything I did last times, I did it all again and more, nothing works, The grub is the newest, 1Ubuntu7
There are a few weird things I find:
* The Nvidia seems to been gone. only the common-directory was there.
* The nvidia was gone and Nouveau is back! I did not and do not understand .....
Now using a Live USB, I can back into it, but:
* I have removed video Nouveau
* The Veza is off
* Current Nvidia installled
*But once I reboot everything is as it was earlier on. All changes DISiAPPEARED again.
Then I looked at the grub, which looks ok to me. I have the 1.98 1Ubuntu7
* The terminal does NOT operate from the USB stick yhe command: mount/dev/sda1/mnt sudo "not
* Similarly, then, sudo grub-install / dev / sda - root-directory = / mnt "says" unknown command "
What happens STARTING UP: : start, pause, image fade equally, without keys, I see then Grub here and can I get a kernel mode (the latest), and sometimes even heavy images, then flash an orange ubuntu color along and then stops the lot, flashing in root (in black) Evil, BUT so I can login. But not IN a nice interface. Any way. Ladies and gentlemen, thank you for the help Another important issue may be, someone suggested doing an update, to remove 2.6.32.21 kernel, which is no more also, Can that be the problem? Even through the live stick or through these kernel booted right? To be sure, the stick is made on Sept. 14.
