Can't load SUSE

Hello, i have one big trouble here.
I’m trying to install SUSE 11.2 on my Dell inspiron 1501 after disk formating, but after the final installation phase(after auto configuration) my screen goes black and i can’t do anything… Same problem i had few days ago, when i managed to install it somehow, but then sometimes (one time out of three) i had the same problem during system startup, when loading bar filled to about a half and then screen turned off(power LED still were on, but HDD were off) and nothing happened, system didn’t loaded. On this laptop i also have Windows 7 installed.
My laptop’s specs:
AMD Turion 64 X2 Dual-Core Mobile Technology TL-56
ATI Radeon Xpress 1150 256MB HyperMemory graphics (integrated)
2 GB of RAM
120GB HDD

Its possible the default radeon or radeonhd graphic driver failed to configure properly.

What you could do as an iterim, is try the fbdev or vesa graphic driver.

Then later either update your radeon/radeonhd graphic drivers, or install the proprietary ATI graphic driver.

My apologies if I guess wrong but I suspect you may not be familiar with the openSUSE ways of doing this. So you could take a read of this practical theory guide here: openSUSE Graphic Card Practical Theory Guide for Users - openSUSE Forums

In particular pay close attention to post#1 and post#11.

For example, to try the vesa driver, you reboot your PC and at the very first boot selection menu, press “3” (no quotes) such that 3 will appear in the options line, separated by a space from anything else that might be in that line. Then boot normally. That should take you to a full screen text login. Login as your regular user with associated password. Then type “su” (no quotes) to get root permissions (enter root/admin password). Then type:

sax2 -r -m 0=vesa

and configure your graphics with the sax2 tool. If that works, exit sax2, and then reboot with (with root permissions):

shutdown -r now

and this time do not press “3” at the boot menu.

To halt the PC, you could instead type:

shutdown -h now

I dont have SUSE properly installed right now, i cant finish installation because of this issue so i cant try this i suppose…
Is there are any way to set these commands during SUSE installation? So i could install these drivers during SUSE installation?

I guess I misread your post.

I saw this:

… and from that, I assumed when you rebooted you obtain a boot selection menu (called grub) where you could select windows, openSUSE, or openSUSE fail safe. … If you don’t get that, then my advice is not applicable.

I managed to get it started now, so i guess now i need to install radeonhd drivers to get rid of this problem…

Congratulations.

Please again read post #1 and #11 from this guide to give you an idea about this:
openSUSE Graphic Card Practical Theory Guide for Users - openSUSE Forums

… it is possible the radeonhd driver that comes with openSUSE-11.2 as packaged may not be good enough, in which case you may need to follow the suggestion in post#11 to update the driver, before using the radeon or the radeonhd driver.

If that post#11 guidance is too general, please advise so we can try to help you further.

Good luck.
