ubuntu 8.04 installation problem: blank screen.

[Li Yu]

I tried to install ubuntu 8.04 amd64 by grub4dos and casper means, but this try failed.

The GNOME in Live CD can startup without any problem, but LCD screen will be turned blank suddenly after running some periods(this time interval vary from some seconds to two or three minutes). I ever used google to search some sites, someone said it is possible to due to splash, but there is no any splash kernel parameter in grub configuation.

When the screen is blank, the leds on PS/2 keyboard show that the system still did not hangup *sometime* (I can switch them), but the led of my optical USB mouse is be turned off. And in this time, I can not switch virtual terminal too. Also, I can not reboot by press Ctrl-Alt-Del, so I must press that Big-Red-Button to reset *_*

I tried below some means:

1. add kernel parameter noapic, noapictimer, pci=noacpi.
2. replace digital cable with old VGA cable.
3. change some BIOS setups.
4. Ubuntu 8.04 am64 server can install (by CDROM) on my PC successfully.

My PC configuration is:

1. SOYO A-780+ (AMD 780G chipset)
2. AMD Athlon 64x2 5000+ (blackbox), no overclocking.
3. No other display adapter.

Thanks .

Well, I installed 8.04 sucessfully by alternate CD, and installed the latest ATI closed source driver later. But the blank screen still will occurr. So I think this likely is not due to driver, huh?

If I used recovery mode entering system, then run "telinit 5" to startup X window, all is ok. my pc can run about one hours without any problem in this way, at least.

I just tried to remove both "quiet" and "splash", sadly, the blank screen still exists......

and In fact, I remember that I also ignored these parameters in kernel boot parameter line in grub menu.lst.

My meaning is I have been ignored both parameters in casper installation.
