Ubuntu 10.04 Freezes sometimes when I boot up!

[TheNerdAL]

I have been posting some threads about this but they don't help much.

So I boot up my computer and sometimes it freezes with a white underscore on a black screen and my Caps Lock and Scroll Lock blink.

Sometimes it doesn't freeze but just the underscore starts blinking. What could be the problem?

Thanks.

This is why I went back to Ubuntu 9.10, can anyone fix this?

Will this help?

...Other graphics card users may get a black screen with flashing cursor and then a very short duration plymouth.

One fix for this is to create this file.

gksu gedit /etc/initramfs-tools/conf.d/splash

and add this option FRAMEBUFFER=y, save the file.
Then

sudo update-initramfs -u

Plymouth now has a hard dependency on mountall thus trying to remove Plymouth would remove half the OS. The advice is, if you don't want a graphical boot then uninstall any plymouth themes.

If the problem is a slow boot, and you have no floppy drive, disable the floppy in the bios. This has been reported as a fix to this. https://bugs.launchpad.net/ubuntu/+s...ks/+bug/551712

If the problem is plymouth not displaying, and a black screen from grub to gdm, this could be due to graphics drivers needing to be loaded quicker. This is bugged.

I have the same problem on my dell E521 with an ATI graphical card. I noted that the freeze happened when switching to polymouth.

Can't help with a solution I'm afraid but the slowly blinking LEDs indicate a kernel panic. You may try raising elephants to at least reboot cleanly. Other than that, sounds like an issue with hardware, most likely video as other posters suggested.
