hey... recently i have tried to install ubuntu 7.04 (2007) on my pc...but the thing is that the installation screen hangs (becomes black) as soon as i choose the option install from cd.
the cd is ok bcoz it got installed on my frnds pc....i have a 82845g graphic card..which went undetected on fedora 7 earlier but i heard that ubuntu has preinstalled drivers to support my graphic card and i will be able to see a good resolution after the installation process but m stuck with the black screen in the beginning...waited for 10 min but no use...its the same blank screen! plzz help me out as to wats the problem!!!

try doing an install without running live...

Installation from the Alternate Disk uses 64Mb of RAM. Installation from the Live CD takes 192Mb of RAM. Could the amount of RAM be a problem?

well i have 256+128 mb ram.
i think that should be enough!
will doing memory test help out??
what changes should i do to run the installation?? ppl please help m a newbee u c!

Describe your computer (ie make/model/mobo/hd controller/etc).
Can you boot a Live CD or is this problem only when installing?
You may have to specify some boot options, the most common ones being turning off acpi and apic.
As for running the memory test, sure run it, just to eliminate it as a cause of your problem.

If you get a blank screen during installation , the most likely cause could be that the x server cannot be started. This mostly happens when it has set up ramdisk and basic drivers.So this could be because your distro may not have the drivers for the card you have. Both fedora and ubuntu give you the option of usinga vesa mode instllation. Here the vga is configured for the basics. and you should be able to see the installation screen. If ACPI or APM were the causes, you should have seen the error message while booting and most distros automatically turn off ACPI if there is a problem. Give it a try and let us all know.
